if our universe is, say, a balloon that's expanding... what's outside of the balloon? there has to be space (no pin intended) for it to expand in, right?
Otherwise,is our universe creating space as it expands?

Every major house lives in a different climate and has its own regional culture.

Before that, the claimant Renly Baratheon was assassinated by his brother Stannis Baratheon. Stannis then tried to attack the capital city Kings Landing but failed and lost most of his army, and runs to the far north in order to stop an invasion of the continent by a race of mythical ice-men.\n\nIt remains to be seen:\n\n1.

", "Every action you do that involves credit (take out a loan, open a credit card, get a credit card bill, make a payment, miss a payment) is reported to one or more of the three credit ratings companies (yes, they're private companies). They then apply their secret algorithms to all that data and come up with a number between 300 and 850 that approximates how likely you are to pay off your debts. If you've nearly maxed out all your credit cards, are behind on your mortgage payments, and don't have a history of paying off debts on time (not that you've necessarily missed payments before- it's also bad not to have any credit history), you'll have a lower score.\n\nWhen you request more credit, whether it be another credit card or a new mortgage, the creditor looks up your credit score and determines how much money they're willing to loan you and what interest rate they'll charge based on your score. People with higher scores are lower risk of defaulting, so they'll offer a lower rate and larger loans." ] }

Investment banks create securities. [oversimplified]\n\nFirst off, most banks are commercial banks (aka retail banks). In general they take deposits from individuals and make loans, as well as offering services like credit cards. \n\nInvestment banking works more with the markets directly relating to financial securities (stocks, bonds, derivatives, etc) and financial advisory services. But investment banks do not take deposits. \n\nWant to have your company go public and be listed on a stock exchange? The can determine a listing price and distribution. Need to issue $10B in bonds, they can partner with other firms to create the terms and get them sold. Want to merge with another company? They help with due diligence and the terms and the funding (loans, stock conversions, etc.).\n\nTraditionally (at least since the 1933 Glass–Steagall legislation) these were separate institutions. Many banks collapsed (for instance) when they used deposits to speculate on the markets. These functions are still separate but can be housed in one corporation. And most investment banks chose or were pressured to become commercial banks (at least from a regulatory perspective) after the crisis of 2008.", "The most ELI5 interpretation of them is that investment banking has one job, and that job is to help their clients find money for their business. They find investors. They help companies merge etc.\n\nBy definition, **Investment banking** is a special segment of **banking** operation that helps individuals or organisations raise capital and provide financial consultancy services to them.\n\n [_URL_2_](_URL_2_) \n\n & #x200B;\n\nInvestment banking sells services. They can help you whether you want to buy something, or sell something. They aren't the buyers or sellers themselves, they are advisors. All investment banking activity is classed as either \"sell side\" or \"buy side\". The \"sell side\" involves trading securities for cash or for other securities (e.g. facilitating transactions, market-making), or the promotion of securities (e.g. underwriting, research, etc.). The \"buy side\" involves the provision of advice to institutions that buy investment services. Private equity funds, mutual funds, life insurance companies, unit trusts, and hedge funds are the most common types of buy-side entities. taken from [_URL_0_](_URL_1_) \n\n**DO NOT CONFUSE INVESTMENT BANKING AND INVESTMENT TRADING.** They have touching points but they are not the same. Investment banking will help you get your company on the open market so you can sell your stocks (1st hand). Investment trading will buy your stocks, sell them forward (2nd hand), and also deals with many more financial instruments (option trading, bonds, FOREX etc.)\n\nP.S. if you wish to lose all knowledge of investment trading and descend into madness, go to r/wallstreetbets and leave your sanity at the door.", "Investment banks are companies that work with investments - for example, they help companies to issue stock and bonds, advise on buying other companies or assets, create derivatives based on the value of underlying assets or indices, trade financial instruments, create structured products like securitized mortgages or loans, all that fun stuff. They also don’t traditionally take deposits - you aren’t supposed to be able to open a chequing account with an investment bank. They work purely in the world of capital markets, mergers and acquisitions and sometimes wealth management.\n\nInvestment bankers basically are people who work for investment banks or investment banking arms of full-service banks. The career is typified by very long hours and high pay.", "Let's say you own a bakery. You need money to expand. So you go to a normal bank and get a loan.\n\nNow let's say you own 10,000 bakeries and you need money to expand each one. You could go to a regular bank and get a loan, but you might not like the terms or they might not be able to lend you all that money. So instead, you go to an investment bank. The investment bank finds a bunch of investors who want to lend you money, and helps you issue bonds to those investors (a bond is essentially a promise to pay someone back for a loan they made you). Or, the investment bank helps you raise the money by finding investors who want to buy part of your business, and helps you navigate the various requirements for you to issue stock to them in exchange for the money.\n\nInvestment banks also offer advisory services, like helping you analyze whether to purchase that other chain of bakeries who is your main competition.", "Think real estate agents. Every time you want to buy or sell a house, you get an agent that does the heavy lifting for you and takes a percentage cut. \n\nIB does the same when a firm needs to buy, sell or IPO. The process to do these require a lot of specialized knowledge on the area and market conditions and firms are better off outsourcing these fairly difficult and niche tasks (like buying or selling a house, only really happens a couple times in the life of a firm) to experts who who do this day in and out. Just like making a bad real estate investments, a bad M & A (mergers and acquisition) or a bad IPO could be ruinious to the firm in the short - medium run, so firms are willing to pay the massive fees that these IB firms command. [2-3% of $1B raised is a lot of money]. \n\nI think the real estate agent analogy holds for a lot of these. Some clarifications: \n\n1. Yes, IBD does only mergers, acquisitions, and IPOs. For other related activities like raising debt capital, there are other related teams in the capital markets division of the banks. IB sits under capital markets as well.\n\n2. Why is it so lucrative? Surface reason, money. 2-3% of $1B being earned by a team of ~10 IB is a lot of revenue per employee for the bank. They get bonuses accordingly. Also, the work you do is incredibly impact. You can be working on the biggest deal in the industry that year and advising on where $1B+ of capital is going to be deployed!\n\n3. Is it a lot of work? Yes. These deals are usually massive and have a lot of work that needs to be done before. It is also extremely time sensitive. So during crunch time its not uncommon to put in ~100 office/week at the office. \n\n4. Usually called the sell side of the deal because it is usually the seller who bears the 2-3% fee that bankers charge (just like real estate agents again!)", "There are two things you're asking here OP:\n\n1. What an *Investment Bank* is\n2. What *Investment Banking* is\n\nFor number one, there's basically two sides to an investment bank: the side that deals with doing deals, giving advice and raising capital (the **Investment Banking Division**) and the side that deals with making markets for investors, brokering ideas to large investors, creating new securities and publishing research (the **Sales and Trading** or **Markets** division).\n\nFor the second question, you can liken the investment banking division to a couple of things: 1.**account managers**, 2. **realtors for businesses** and 3. **mortgage and home equity brokers for businesses**.\n\n1. As **account managers**, bankers working in an **industry group** will be the first point of contact for a company within a specific industry. They'll be the ones who own the relationship, provide ongoing strategic advice, oversee/represent the companies during any transactions (i.e. company sale or capital raise) and if there is no dedicated realtor team (M & A team) to execute the sale they will do it themselves.\n\n2. As **realtors for businesses**, bankers represent clients looking to sell their business or looking to buy a business. In the first case, they'll figure out how much that business is worth and try to connect the seller to appropriate buyers. In the second case, they'll help screen for potential businesses to buy and will organise the whole process of buying said business.\n\n3. As **mortgage and home equity brokers for businesses**, bankers help raise money through a mortgage (i.e. debt, most oftentimes a bond) or by forgoing some piece of the \"home\" for money (i.e. equity, selling pieces of the company). The difference is that the banks also initially administer/co-administer the mortgage (purchase the bonds by themselves or as part of a syndicate) or buy the entire piece of the house (purchase all of the new stock being issued) usually all of this at a discount, this is referred to as **underwriting**. They will usually find investors to pre-agree to buy the debt or equity from them before buying it themselves so they don't take on too much risk - because it was at a discount they make a decent profit on selling it on. \n\nNow, the above differs a tonne:\n\n- The \"IBD\" (Investment Banking Division) could just represent the first two types of banker (the \"account manager\" and \"realtor for businesses\") and there could be a separate \"Capital Markets\" division that handles the third type (\"mortgage or home equity broker for businesses\"). \n\n- An investment bank could also be \"independent\" and not have a \"Sales and Trading\"/\"Markets\" side; these firms are usually referred to as \"independent advisors\" because they can't underwrite any debt or equity since they don't have the money (balance sheet) to do it.\n\n- There are also other teams that fall under investment banking that I didn't get into for the sake of the ELI5 including: Public Finance, Leveraged Finance, Corporate Broking, Ratings Advisory, Risk Management Solutions and a bunch of other niche teams.\n\nHope that's helpful." ] }

This way he could claim it to be as scientific as he wanted, while still allowing himself to present it as mystical when it served his intent.\n\nThe more generous side of me accepts the \"company line\" on the meaning behind the name (after all, what do I care what the name means, it doesnt change whether I do, or do not think it's all true). That company line is that the word is based on the latin scio, meaning \"knowledge\" and the greek logos, which is the root for the suffix \"-ology\", meaning \"the study of\". So the name literally means \"the study of knowledge\". Since the religion makes claims about increasing one's knowledge about self, the universe, and one's relationship with the universe I think its actually a fairly clever name. \n\nWhat they actually DO, and what their name means are entirely different things, and just because their name is clever does not mean their ideas are.

Every chili or sauce has different components with different amounts of capsaicin in different parts of the plant, therefore it is often difficult to measure the exact \"spice-level\". It is still more usefully and accurate than the old procedure. \nThere are a lot of crazy methods for classifying hotness, for example the ***Dremann Hotness Scale*** where the chili are measured in their spiciness in relation to the salsa they are in. \n\n\nHope this helps and I apologise for any grammatical or orthographical errors, English isn't my first language.\n\nEdit: Some formatting", "Originally, the Scoville Scale was a human-driven test. The dried peppers were powderized and diluted in sugar water, and a panel of 5 humans tasted the dilutions until a majority of them detected spiciness. If that dilution was, say, 1/1000th of the original solution, then the scoville rating was 1000 * 100 = 100,000 Scoville Units.\n\nBut this scale had flaws: Between labs, you could easily get a 50% difference in ratings. So a new unit was developed: Scientists established a standard curve for spiciness, and then looked at what chemicals were in each level of spiciness using a tool called High Performance Liquid Chromatography. They made a new scale based on **American Spice Trade Association Pungency Units.** But because Scoville was already publicly known, they came up with a conversion between ASTA Pungency Units and Scoville: 1 ASTA Pungency Unit = 16 Scoville Units.\n\n**TL DR** Originally, Scoville ratings were done with an elaborate taste test. Today, Scoville ratings are calculated by a lab test based on chemical composition of the peppers.", "Since people are answering HPLC, and HPLC is absolutely not something a layman encounters often, I'll take a stab at simplifying it. \n\nHigh-performance liquid chromatography is a way to 1) separate all the different chemicals in a mixture and 2) learn how much of each chemical there is in that mixture. Since peppers are spicy because of a specific chemical, capsaicin, they can look for that chemical in an HPLC experiment. The way it works is that as each different chemical goes through the machine, it interacts with the makeup of the machine differently. So, some chemicals will go through faster, and some slower. Since they know how fast capsaicin flows through, they can identify it and measure how much there is. So, they mash up a pepper, run the juice through the machine, look for capsaicin, and there's your Scoville test!\n\nHopefully that helps!" ] }

why are diamonds still so valuable?
It's pretty common knowledge that the diamond market is controlled by the companies who own the mines, and we can make diamonds artificially in labs. Why haven't we collectively decided not to pay so much for them anymore?

They always keep supply available well under the demand, which helps dictate a higher price", "Its is common knowledge on this site were many people post it over and over and over. \nIt is pretty easy to think that something is now know to everybody because you have read it here several times. \nThe truth is: Many people still think they are rare, they are sold for a high price and people still pay them because they think thats how its supposed to be.", "The tradition of buying diamond rings for proposals is some of the best marketing an industry can have. As long as the companies who make diamonds can keep associating their product with love, they'll always be able to sell them at a higher price. Love is something that is universally, uh, loved, and love makes people do stupid things.", "Alright, I'm finally annoyed enough at seeing \"fuck diamonds\" posts to say something about it. So without further ado....\n\nThe early 20th century was a different time with different morals. Premarital sex was far more taboo than it is today, and women did not work as much as men did, the expectation being that they find a husband to support them. Also, it was very important to most potential husbands that the woman be a virgin before their marriage. Keep these things in mind.\n\nNow, even though premarital sex was frowned upon, men still wanted sex without necessarily committing to a lifelong relationship. This lead to some men leading women on with a promise of marriage, using her for sex, and then leaving her when he got bored. This was very bad for the woman because now that she was no longer a virgin, she would have a much harder time finding a husband, and by extension, financial security. This was a serious enough issue that breaching a promise to marry was actually a crime in many jurisdictions and the man could be forced to pay damages for the woman's emotional distress and decreased earning potential. \n\nKnowing all this, De Beers sensed a marketing opportunity. They told women that if a man wanted to propose marriage, he should prove that he wasn't doing so for underhanded reasons, and the best way to do that would be to make a significant financial commitment to the woman he wanted to marry, upfront. And it just so happened that De Beers had the perfect way to make that committment: buying a beautiful, diamond engagement ring! (Because handing someone a stack of cash isn't terribly romantic). Now, men were essentially paying a deposit when proposing marriage, one that the woman had no obligation to refund if he didn't hold up his end of the bargain,~~and that she could convert to money (by selling it) to have some means of supporting herself after a broken engagement and loss of reputation~~. After further review, I don't think resale value factored into this as De Beers worked very hard to make resold diamonds worthless, by cutting off jewelers who accepted second-hand diamonds.\n\nWhy is it still around today? People have largely forgotten the origins of the tradition and just see it as something you're supposed to do. Societal change is slow and this is something that will probably die out or change as time goes on and the wealth/power imbalance between men and women gets smaller and smaller.", "They're actually less controlled than most think, as a bunch of competing producers have popped up and broken the monopoly very recently (the big one is run by this nutty Israeli guy). At the end of the day, though, diamonds still require a lot of resource and labor to obtain and process.", "I don't have an answer to the question but I do have a fun fact about diamond engagement rings.\n\nThere is a common misconception that diamond engagement rings are an ancient tradition. Sure, there is a rich history of rings being exchanged during marriage ceremonies, and there have also been a variety of circumstances where royals and other elite gave diamond jewelry for an engagement. But, it wasn’t until the De Beers diamond cartel decided to funnel millions into marketing and advertising campaigns that the diamond ring became deeply embedded into the culture.\n\n**[Here's a quick video about the scam.](_URL_0_)**\n", "Most people here haven't addressed the question, they've just reiterated the problem--why do people think diamonds are rare and valuable, still? And most people just say that it's because of marketing, basically. But *why* is the marketing still effective? Don't people know better than that now? So my answer is that it's at least partly due to the fact that people don't buy diamonds for themselves. The consumer and the purchaser are different. So while a person might have a certain standard if buying for oneself, they will defer that standard to the person they're buying it for. Women, having it bought for them, have their eyes on tradition, prestige, and bragging rights for diamonds. If they were to not have a diamond engagement ring and say that it was their choice, people might think it's sour grapes, because their man was too cheap to buy a diamond for them and they were just lying when they said they didn't want one. The man might think yeah, I've heard these are worthless, but my woman wants it, and so I'd better get it for her or I won't hear the end of it. So basically, it's this particular dynamic between the person buying the diamond and the person the diamond is being bought for, that leads to the diamond economic bubble--the continuing high valuation of diamonds despite it being built on lies.\n\nThere's also the fact that people have long valued diamonds, so deciding they're not valuable at all would be tantamount to saying that something one has a lot of is worthless. That is, it would be offensive to other people to say that diamonds are worthless, so people don't want to say it or admit to it. People want to continue to believe that what they have is valuable. Kind of like how,have you ever encountered someone who has fallen for that internet scam where someone writes from Nigeria claiming to be the widow of someone important, and they want your help in transferring some money, and if you help you'll receive some huge amount of money in return? People who've fallen for that, and lost huge sums of money paying \"fees\" for the money transfer, become really committed to believing that it's a legitimate request. It's too painful to think they've been scammed and that they've lost all their money.", "Because people are stupid and believe what they want to believe.\n\nthat's really all it is.\n\nDo you know why words with english and german roots are considered obscene?\n\nDo you know why parents STILL hit their kids?\n\nDo you know why school classrooms are set up they way they are?\n\nDo you know why Brits drive on the wrong side of the road?\n\nBecause we've always done it that way. We're way past trying to impress our French overlords with our language, we're way past sending our 9 year olds to backbreaking labor, we're way past groups of clerks working in a room that looks like a classroom with their boss facing them instead of a teacher and we're way past London cab drivers hitting British pedestrians with their whips on when on the right side of the road.

Hopefully this makes sense. Kind of embarrassed that I have gone 21 years without being clear on this.

Over the course of approximately every month, the sun and the moon have a race around the earth and the sun is always slightly faster than the moon. At the start of the race, both of them are at the same point and the moon is not visible at all because all of the sunlight on the moon is on the side we can't see from earth. Over the next few days of the race, as the sun creates a small lead, some of its light can be seen as a sliver on the moon but only at a point during the day when that sliver of reflected sunlight isn't completely dominated by sunlight in the sky: just after sunset. As the sun increases its lead over the moon over the next several days, the portion of the moon that is visible increases and the \"distance\" between them in the sky increases so it becomes easier to see the moon during daylight hours. The sun's lead continues to increase, until a point at which we see a full moon and the sun and moon appear to be at exact opposite ends of the sky, ie - moonrise occuring just as the sun sets. This is the halfway point of the race. During the next half of the race the reverse starts to happen, where at first we see all of the moon all night and then it sets just before sunrise, then we see slightly less of the moon for most of the night and then for a little bit after sunrise, then we see the moon for the later parts of the night and for longer during the day but with it becoming less and less visible as the sun appears to catch up to it over the course of several days. This pattern continues until the point where only a sliver of the moon is visible only just before sunrise and then eventually the race ends and they are both at the starting line again and the moon is no longer visible." ] }

why are software companies shifting to subscription packages rather than outright purchases?
Companies like Adobe and Celtx and more and offering only subscription packages and no options for single purchases. What if I want to pay once to just own the current version that does everything I need?

They allowed it because many of the Pirates were learning graphic artists, so it basically built their customer base. \n\nThe change to a subscription model is a pretty brilliant way to enforce purchase, but make the software cheaper, and in turn make more money than they were before. ", "I cant believe that nobody has mentioned piracy yet, many people could pirate a 100+ dollar program, never update it so they dont lose the software and keep it free for life. You cant pirate a subscription, Adobe products are some of the most highly pirated and a subscription keeps them from losing revenue to pirates.", "All the other answers here are right, but I don't see a lot about the ops portion of this. If you've ever worked on the backend of a software, being cloud based makes maintenance significantly easier. You don't have to deal with versioning, maintaining support and bug fixes for old versions, etc. You're also only maintaining one code base and you can easily push out updates to your software and monitor your usage. ", "If the requires continuous updates and upgrades it is more cost effective for them to charge as subscription fee for their work. It is also easier on the customer to buy a piece of software once and pay a low subscription fee than it is to buy a completely new set of software when the next edition comes out. ", "Same reason Streaming is promoted over legal file downloading. They are basically switching from selling a product to rent seeking.", "I work in software development. This strategy is called \"Software as a Service\" and is becoming the new norm. There are rumors Microsoft is moving towards this model with Office too.\n\nThere are two major reasons for this strategy. The first has already been mentioned - piracy. \n\nThe second reason is more complicated: the development lifecycle. \n\nA) It is too lengthy for the current consumer and less profitable (at least in the short-term, arguably in the long-term depending on the success of the product).\n\nA good example of the development lifecycle being too long is to look into Early Access games on steam. On average, even a small quality game takes 3 years, but that length of time receives a lot of negative feedback to the developers. Users don't really *understand* what goes into software development and therefore don't have the patience to wait.\n\nB) But on top of that - the world is a lot more competitive. The earlier you get your product out, the more likely your product is to dominate the market. (Or at least this is the perception of management.)\n\nC) Users are finicky and expect a lot more out of their products now. For better or worse, they expect their feedback incorporated into the software.\n\nD) Probably one of the most major factors - Success of an old-time software development lifecycle is unknown until the product is released. And by then, major changes are too late. You see this a lot in video games for console, and it puts some smaller companies out of business. The service model completely prevents/bypasses this. The developers can respond to feedback to improve user experience and lower the risk.\n\nThere is the negative side too though that isn't really acknowledged because it's bad publicity. This is the 'customer is always right' model, and in software development this is often far from true. It also demands quicker development, which means bigger teams and faster fixes, that are often detrimental to the product.\n\nRegardless, it is becoming the new norm, and will likely remain that way for some time.\n\nThe biggest risk against it though is exactly what you've mentioned: another bill to pay. Long-term are users going to be willing to add so many bills for luxuries? Netflix, spotify, youtube has a subscription model now, office, photoshop, etc? This shit is going to add up.", "Because money. If you buy a package and then don't upgrade for years, they lose out on revenue. Subscription keeps the money coming from as long as you use the program", "A couple of reasons. Firstly, the company can determine how much income they'll have at any given time because it's constant (individual sales are usually inconsistent and mostly random).\n\nSecondly, more money. If they make you rely on something that you have to pay for monthly, they've got you. They'd rather have $10/month off you rather than a single $100, especially for something you're going to keep for a long time.", "Long story short, many things are switching to subscription because it's easy to make the customer think he's getting more out of it, while generating much more profit for the company. Simple psychological behavior, like the sunk cost fallacy, means that many customers keep paying the (otherwise smaller) monthly fees, end up paying many times the cost of the one-time package, but the company does not have to spend more effort or resources on it, just reroute it differently.", "Along with the other reasons listed, a subscription model offers a lower barrier of entry in terms of price. With the Adobe Suite, before now pirating it was the only real option for non-professionals, now its actually feasible for a student to pay for it.", "My theory is this:\n\nSoftware utility hasn't really improved much in the past 10 years. Really, what can the average user do with Office 2016 that they can't do with Office 2007? Or a lot of other programs, IMO.\n\nSo there really is no compelling reason for people to \"upgrade\" any longer. In order for software providers to continue to make money, they have to come up with a different method of charging for their products. If you bought Office 2007 eight years ago for $499 (about $5 per month, if you paid full price), and only use it for simple office tasks, such as letter writing, spreadsheets, etc., it will work for you for another 8 years. Why spend another $500 for features you don't need?\n\nBut the subscription model requires you to pay and pay again, as long as you are using the product. So the software companies have a reliable stream of income forever.", "Lot of reasons and most important ones are\n\n* Software companies want every user to have the up-to-date version of their software, which translates to easier patches, better security etc.\n\n* To enforce up-to-date the software company you can't make them buy their newest version every time. The only viable option is give the updates free or charge them by subscription packages.\n\n* The book keeping for companies that buy packages is easy because they don't have to worry about long term assets ( because when you buy the software and use for 3 years, then you have to handle the books differently ).\n\n\nSimply it is the best way to sell and deliver software.", "A lot of responses say 'money' but if you break it down, companies that upgrade regularly [may actually end up spending less](_URL_2_). Adobe, for example, have priced Creative Cloud in such a way that three years subscription is approximately equivalent to the old CS6 Design Standard (although you actually get a lot more with Creative Cloud so it's arguably a much *better* deal). The operating costs for Creative Cloud are substantially higher as well (as Adobe have to provide an always-on cloud service) which has led to a[ *decline* in profits](_URL_1_) since releasing Creative Cloud.\n\nThe old way of developing was that you worked on a product, adding features and ironing out the bugs until it was 'ready'. At this point you wrote it to a disk, printed the manuals, stuck it in a box marked *Version 2.3* and shipped it to a store to be sold. Then when your customers found some problems you would work on solving them, go through the whole process again and in addition supply your loyal customers with a disk marked *Version 2.31*. This way of developing is, as I'm sure you can imagine, very outdated in a world of downloadable installers, endless software updates, etc. But it's still the primary model for development for a lot of our most used software. \n\nA subscription model allows developers to adopt more of a *[rolling release](_URL_0_)* approach to development, which should allow for more innovation through faster iteration. That's why the big players like Microsoft and Adobe *say* they are moving to subscription models; we will just have to wait and see whether it delivers the goods as promised." ] }

People like money, nay, need money to survive.\n\nIn the case of a full fledged game, they can require a staff of five to fifty people to get a product to market in a reasonable timespan. If you're planning to get it out within the year, you could easily be expecting production budgets in the multiple millions to pay for staff and hardware.\n\nPredominantly, kickstarters are made to birth studios, not just a single game. As a result, the kickstarter is usually funding more than the first game.", "Expensive workers using expensive tools.\n\nSuppose you have five workers earning $20/hour? That's over $5,000 for every week of development! \n\nSuppose you have some really passionate developers willing to work poverty wages? Paying two people $5/hour for two years is still $20,000.\n\nThis is before we even cover other costs. Hardware and tools may cost over $3,000 per employee, and there are taxes and legal fees. Don't forget that Kickstarter takes a cut, and that many projects lose a huge chunk of funding, maybe as high as 30-50%, to backer rewards.\n\nAnd *marketing*. Do you really think it's reasonable to spend forty grand making a game, and market it without spending a dime? Looking at major publishers, marketing is sometimes just as much of a cash drop as the development, itself.\n\nIf anything, the question isn't why their budgets are so high, but why they are so low.", "To add on to what has already been posted, game engines require years to design or they require lots of money to license. While there are engines that have licenses for as low as $99 to $1,500 the big league ones like Unreal can cost well over $1,000,000 to license.", "Indie developers can build games somewhat cheaply by keeping the scope low and doing the work in their spare time. However for games that are intended to compete with big titles the economics change quite a bit.\n\nSay I want to build a game that has a 3D character that can perform certain kinds of attacks and special moves and I need it to look at good as the latest games on the market. *For the purposes of the below you can assume a typical developer at this level costs $2500-$3500 per week.*\n\n1. First the initial concept needs to be created for the character by a professional game designer. This is just the basic *idea* of the character and what he/she will do. This process can easily take several weeks.\n\n2. Next we have a 2D concept artist draw the character. This is a multi-stage process where we start with *thumbnail* sketches to find the basic look we want and then iterate on or more designs, getting more detailed as we go. Feedback from designers and any investors cause more iteration until we get a final full color concept that usually has callouts to show specific things like what materials the clothing is made of. This process will take weeks and possible more than a month of concept artist time. It also required small chunks of designer, animator, and 3D artist feedback time.\n\n3. Now we need to create a 3D model and texture. It can take 2 months to fully model and texture a next-gen character. If we outsource this to China a typical character can cost $5000, if we do it in-house it can cost more than twice that. Additionally we need to setup the character material (what is shiny on the texture and what is dull, how does light affect it?) and this takes about a week of a technical artist's time.\n\n4. Now we have a character but he doesn't move. So the next thing we do is called *rigging*. This is where we create virtual skeleton inside the model, where virtual bones are *skinned* to the polygons of the model so they move when we animate the skeleton. This process is an art in itself and can be take over a week to complete. It takes even longer if the character has cloth or special features like wings or tentacles.\n\n5. Now the animators take over. For a leading character we may need to animate over a hundred different moves. Even a simple walk cycle needs several animations to handle transitions, turning, reactions, etc. We may have 2 or 3 animators on one character for a few weeks so the cost really adds up. Motion capture doesn't save much time either because of the cleanup time and initial cost and setup.\n\n6. Now we have our character and it can move around but it need special effects. Blood, dust, smoke, magic, etc. This can vary depending on the game but can be anywhere from a few days to a few weeks.\n\n7. We can't forget audio either. In AAA games each character may have its own unique footsteps sounds. Every surface the character touches may have a unique sound attached to it for dirt, metal, wood, etc. All the abilities have sound effects and then you have voice. Voice recording at this level requires hiring professional actors, even if all you are doing are grunts and effort sounds. (Trust me, there are people who are professional at grunting and the difference is quite noticeable). Sounds effects for one character can take a couple weeks not including voice. Voice can more than double that and that is assuming we're not recording for a long cut-scene.\n\n8. After all that, none of it is going to work until we have a programmer write the code to determine how it behaves, how it moves, when it attacks, etc. This process happens at the same time as the above steps but often requires *months* of multiple programmers working with one or more designers.\n\nOverall, if you include all the design and production managing this process it can cost $100k-$250k *for a single character*.\n\nThe above is just the directly relevant people and just for making a single character in the game. It doesn't include the enormous task of building next-gen quality levels, designing and coding the game rules, building an AI system, creating all the user interface and HUD art, creating cinematic cut-scenes, composing music, camera design, employing an army of game testers to find every bug, *fixing* every bug, producers managing the process, and bizdev people managing the marketing and investors. We also need to pay overhead which covers employee benefits like medical insurance, free food and drinks, office space, etc. \n\nSo something like FTL can be made at tremendously lower cost because it could be potentially made a by just few people working for themselves and doing all the coding and artwork, but something like Star Citizen will need millions.\n\n**Source: I am the owner of a AAA game development studio**", "Most really successful Kickstarter funding goals are usually not just met, but they're exceeded. [Hover: Revolt of the Gamers](_URL_0_) set a goal of around $38,000 and surpassed $100,000.\n\nGames like this set goals after they're been funded indicating what kind of time of money they'll need to add in most things.\n\nMost independent game developers have the hardware and software they need to make video games. Some have to pay for a license from a game engine, but that's all baked into the Kickstarter price.\n\nFor the most part Kickstarter money goes to the salary and wage of the developer or developers. Developers are expected to make between $50,000-$75,000 a year. That might be peanuts in money, but it's what they need to really survive while making video games. They're going to be putting in 12-14 hours a day into making that game so they're going to need money to order take out a lot of long nights.\n\nThe fact is if the opportunity is not there to make a lot of money off of their baby.... why would they ever want to do it?\n\nFor the record Hover isn't a game where they're making crazy money off of. Split between the three developers they're getting $30k to finish up the game in hopes of getting a lot more when it releases. Considering small indie games don't generally get a lot of sales.... that could really be all they get out of it after Steam/XBLA/PSN takes their ridiculous cuts.", "I may be able to help a little bit on this one.\n\nThere are many costs when making a game and it takes a long time. The high costs of developing a game starts at day 1 with hardware. Lets say you have a team of 10 people to make a small game, that is 10 computers you will need. They will also have to be high end computers for modelling and rendering etc. \n\nNext is the software costs for the team, 3ds max has a licence to use for a small office which would fit in with a small team, you also need a game engine where prices vary but lets say they want to make a unity game, that will cost them 1500 or 75/month. There are cheaper alternatives though which they could use. \n\nYou also have to take into account payment for employees which is VERY expensive for 3d modelers and sound people, you will also need coders, artists, writers and more. Lets say a 50k average payment a year for all of them to save time. If the game takes a year to make which is fairly decent time for a good game it adds up soon. \n\nAdvertising can be done fairly cheaply now with youtube/reddit and other social media websites however it can become expensive if you want to reach a large audience, this I am not so good at as I haven't looked into it as much but large AAA games spend MILLIONS on advertising alone\n\nCost of computers - 1000 each / 10 000 for all \nModelling software - 3675 this is for 3ds max which is arguably the best on the market. \nGame engine - 1500 OR 75/month for unity. \nEmployees - 50k a year for everyone\n\n\nThere are a few things I have left out like renting a office and other stuff like that but you get the general idea.\n\n", "programming, 3d modelling, animating and texturing take a lot of time. You gotta hire people or you wont be done in 5 years.", "I can't explain it myself, but I do remember Skullgirls had an Indiegogo campaign for a single DLC character where they broke down exactly where the $150,000 would be going.\n\n_URL_0_", "Indie game developer here. Most development cost for games is LIVING EXPENSES. While there's always an argument to be made for having a second job to cover living expenses, usually people doing a kickstarter are doing it so they can work FULL TIME on their game.\n\n2 people x 2 years dev time x 30k/yr [pretty low baseline for living expenses] = 120k total.\n\nMost people doing a kickstarter for less than that are covering the rest of the expenses in other ways.", "Ex Industry Professional Here\n\nI am not even going to go into the Lawyers, the Marketing and the rest of the nonsense that could come up (building costs etc).\nWhen I worked in a small studio there were 60 of us Employed from Writers, Artists, Riggers, 3D Modelers, Animators, Programmers, Art Directors. etc etc etc\nIt takes all of these people to make a game (50-100 people on average are employed in a small studio). They will cost you (the owner) between 30 and 70k a year. These people have worked for years to learn their skill. One person can not do multiple jobs (well they can but most will be piss poor at it, or there is just no time to do so anyways)\n\n\nThe Process? Man I don't have all night but.... it starts with a lot of arguing and then writing a proposal and then throwing money at the problem by hiring workers (who are hopefully good at what the do) \n\n\nThe Art Director tells concept artists what to draw and works as the liaison between the technical side and the artistic side.\nThen the 3d modeler models the final design,\nthe Rigger adds \"3d bones\"\nThe texture artists strips the model then paints the model\nthe animator then takes those bones and makes them move.\n\nOn the other side, the writers write (a lot) and make many many iterations. \nThey then write the game, they write what will be said in game as well\n\nThen on the other side the programmers will work in a very costly game engine and in a nut shell take all those assets and make it work together.\n\nThen you hire guys to test it, and test it and test it and test it.\n\nThen pay a lot of $$$ to get it off the ground.\n\n\nHope this helps", "Former MMO developer here.\n\n1) Hardware costs.\n\n2) Software license costs.\n\n3) Employee Salary (most of which demand a hefty price for their very highly skilled labor).\n\n4) Terrible executive oversight: This is perhaps the single largest contributor to video game development costs for multiple reasons.\n\nA) Poor Planning: Most executives I've worked with are neither particularly intelligent, skilled, nor well educated. Most of them have been \"socially promoted\" through the ranks, and their increased power promotes what I call, \"the Executives Disease.\" One of its primary components is impatience. Another is a lack of knowing what you want but only knowing what you don't like. Because of this, most projects have nearly zero direction and just a vague set of, \"Let's make this thing that is awesome.\" This is a terrible way to go about creating anything.\n\nFor instance, I worked on a game that was originally intended for 8 to 16 year-old boys and girls. No one that worked on that project (until I got moved onto it 3 years after development began) had any experience with child development. That demographic does **not** exist. The average 16 year-old girl might as well be an alien compared to the average 8 year-old boy. By the way, in the United States at least, that average 8 year-old boy is who is functionally illiterate.\n\n3 years after development started they completely changed how the combat mechanic of the game worked... for the 4th time! And these aren't minor changes. These are changes that completely monopolize the time of the most skilled coders on the team for months or years at a time.\n\nAnd this often leads to the next issue...\n\nB) Feature Creep: This is a common term in development. Feature creep is when a developer has already been giving a list of objectives to accomplish to create a specific thing, and then hours, days, weeks, or months later, a new, major, feature is added into the demands. Again, this can bloat development time immensely.\n\nC) Dropped Projects: I can't tell you the number of projects or features that get planned, have significant development time invested in them, and then are dropped with little or no warning.\n\nAt one point I was tasked with creating a training program for developers to learn Flash. I spent 3 months making this program. However, about 2 months into it, the executives laid off about 50% of our work force, and reassigned about another 25% to a new project.\n\nWe got a \"new\" producer in who lasted about a month, and then he was reassigned. By the time the next producer came in and finally had time to meet with me, he was like, \"What the fuck have you been doing?\" When I told him that I'd made this training program he was like, \"Yeah, we're not going to do that.\"\n\n3 months of work. Gone.\n\nAnd this wasn't the worst of it. I'd seen YEARS of other peoples' work just completely destroyed because of poor planning and poor oversight.\n\nTL;DR: It's expensive to make games, but the worst part is that the people financing and overseeing the projects have no idea what they're doing and answer to investors that know even less of what they're doing.\n\nThe best games and the best game companies are the ones with the fewest executives and/or management and with the largest number of \"skilled contributors.\"", "Kickstarter-er here who ran a campaign that raised 18k but then went on to raise another 600k from investors...\n\nIt was myself + 2 full time developers working 24/7 for two straight years and we burned through the $600k. This is considered an ultra slow burn rate as we really stretched our budgets out and cut corners wherever we could. \n\nImagine that a really great iOS developer costs 120k on the cheap. Now imagine that x2.\n\nYou have a lot of overhead costs that people don't think about. \n\nOffice space? 2k a month\n\nOh ya you're a corporation now, means that you have to supply medical coverage for your employees. Oh your one developer has a wife and kid? That's another 23 grand a year in medical care. \n\nLegal fees, just to incorporate and deal out your shares internally is 5 grand. That was considered cheap.\n\nThere's a lot of realities to building a game. \n\np.s. heres our old game: _URL_0_", "I am professional game developer and I also own a few websites on the topic; Let me see if I can explain as my skills are more back end server development for large scale MMO's, but I am lucky enough to have a wife who does things on the art/client side so I know that as well.\n\nIts an expensive and skill intensive process, skills that most people do not WANT to learn. Its also math intense at times, meaning that its hard and most people would rather not try.\n\nThink about all the things you have in a video game. Lets just focus on this aspect alone, just building the game.\n\nYou have sound:\n\n* Environmental Ambient Sound Effects\n* Environmental Music\n* Game Credits Music\n* Game Intro Music\n* NPC Voice Dialog\n* PC Voice Dialog\n* Non-Player-Character Specific Ambient Sound Effects for every NPC and creature/thing.\n* Player Character Specific Ambient Sound Effects\n* Player Character Specific Voice Dialog for every voice type a player could select.\n* NPC Sound Effects (Interacting with them, bumping them, etc)\n\n.. and that not the full list of sound work you need in most games.\n\nYou have the Graphics used by the Graphics Engine:\n\n* Models - A dragon is an entire model (or possibly a mesh) with multiple textures possible. Somebody has to sit down and mold it using tools like ZBRUSH. And if it is set to allow jointed moment - like your skeleton - it will take a lot more work to build. That can be very expensive.\n* Meshes - Multiple Models working together.\n* Textures - You see that tree log block in minecraft? It uses multiple textures, one for each side that looks different.\n* Banners - Images placed facing the user at all times. Sometimes generated automatically by the graphics engine, or \"hung\" in the air at fixed points either manually - takes a lot of work -or using tools to make trees and plants look realistic. The tools that do this are EXPENSIVE because they have a corner on the market and they do not need to compete with many other tools due to how specialized they can be.\n\n.. and thats all work that needs to be done separate from your graphics engine (the motor of your game that shows you things), but your graphics engine must support it first!\n\nSo somebody - usually multiple people - have to sit down and either make a new graphics engine, or learn and use another one that was built already. These are available, but they are also expensive and also come with legal restrictions. For example it snot uncommon for the prebuilt ones to have rules that say if you the gamer wants to hand the game developer $10 for making a game you enjoy, that they the game developer has to give the people who built the game engine a part of that. I have seen it be as high as 50% - so if you give them a$1 they have to hand over $0.50 - years ago, but the numbers are dropping more and more now as the technology becomes available to more developers. Still, most indy developers build their own rather than use a pre-built engine for exactly this reason.\n\nSo what about input and controls? Adding joystick/controller support is better these days but its still a pain if you are doing it all yourself. As a result that is extra development time and money that needs to be spent.\n\nWhat about multiplier? Well in this case the game just got BIG because now you have to re-engineer the entire system to support thousands of people at once. Any MMO that has at least 200k-300k subscribers is considered a success these days, but the top ones have millions of people at once. This brings a lot of technical issues and that means more work, more people, and more cost. Not to mention, the server infrastructure, the sheer number of computers they need to host these systems, costs a lot of money.\n\nAnd if you want a game that updates? The Content Delivery networks cost a lot of money to host your files, but first you ahve to pay a developer to give you a loader/updater that will use them. So you need them active even before you have a game.\n\nSo we have covered sound, graphics, input, and multiplier and update. What about local save games? Well that's work on its own because if you want to be cross platform and allow yourself to be able to debug issues, you need to have a way to make things secure for players but open to the developers. This usually means creation of internal tools to unpack and tweak save files to do things, and that is more work.\n\nSo now you have graphics, sound, save game, multiplier, and input taken care of. Did we miss anything? Well yes we did.\n\nIn addition to paying for our developers, sound engineers, artists, we also need to do QA (testing) and Planning (Program Managers) as well as the normal people who do accounting and HR or the janitors that keep the place clean. Oh and if you want office space, that going to cost you as well. What you want internet and power in the office building?Taht costs you as well. Oh you want source control so people can work and save their work without worrying about the other guy deleting their file by mistake? That is going to cost you.\n\nAnd these people are all expensive. They have skills companies NEED, and these same companies are willing to spend a lot of money to get them. This means that when a kickstarter is happening, the Indy dev company is competing head to head with the gaming giants of the world for the same people. Often, its in the best interest of the gaming giants to pay their people VERY WELL simple yo keep them out of the free market so they don't go create a game or game franchise that would compete with their own business. So kickstarters are in a very real sense a danger to companies like EA because if they can get funded well then the best people are taken from the armies of the big old game developers and given to the armies of the new, young developers with ideas. And if they do not get funded, well no lose for the game developer as they always have work and companies willing to pay them.\n\nThat is what makes funding indy developers worth it, in my humble opinion.\n\nOh and now that you have your team of 30 or so people for a bare bones minimal MMO project, you have to fund marketing as well. Then hosting, the cost of that will spike after release and then smooth out, but you need to make sure you get new people playing and paying to do so in some way, so it goes up (and so does your costs!). You need a buffer for that or that sudden spike in users can KILL a game as costs increase and the money they pay is up to a month away.\n\nSo you have paid for the development, the marketing, the infrastructure, that is it right? Nope.\n\nYou now have players and that means you are in the \"Gamma Testing\" Phase of Software development; the users will find bugs your QA team never dreamed of, and abuse them ruthlessly to have an advantage over everybody else.. or even just so they can sell the stuff to people for real world money. Yes, RMT (real Money Trading) in games is ilegal and its banned every game due to that, but ti still happens because the bad guys like the money more than they like playing by the rules. So now you have to pay Customer Service Reps to deal with the accounts that are abusive, and Game Moderators (GM's) to protect the game by acting as roving cops looking for bots to kill. Oh wait, not all the accounts running bots are the spammers, they may be accounts broken into that are owned by your good players.. so the tools you need to handle this are intense and expensive.\n\nOh and lets not forget that devs now have to spend time and money fixing these bugs.\n\nOk so we have covered development, keeping the lights on, server farms, marketing, support, abuse, defects. Anything else? Yup. Legal.\n\nLegal is a huge thing because now you have to defend yourself form other big bad companies that simply do not want you to exist. The sheer fact you exist at all makes them angry because that means a customer you have could be playing their game, giving them the money, instead. So you need to hire expensive lawyers to not only cover your ass from the start, but stay around to cover your butt from things as they happen. That spammer that is spamming the local area chat? Yea he is run by a rival game company and just wants to fingerprint your user demographics for competatie analysys to figure out if you are big enough to defend yourself rom a lawsuit he files for no reason at all other than to drain your resources. Or mayb its the irate cusotmer that was stupid and used \"password123!\" as their password, so now the entire republic of korean gold spammers is ruthlessly abusing the account and has already cleared it of anything valuable before changing the password and sending it off to market their spam before it gets killed. Now the customer is pissed thier now empty account is banned and has sued YOU when its not you fault they shared their account in clear violation of your terms of use... but its still going to cost you money to defend yourself.\n\n\nOk so we have covered development, keeping the lights on, server farms, marketing, support, abuse, defects, and legal. Anything else? Yup. There is always something else.\n\n\n\n\n\n\n\n\n", "Oooh lots of stuff! I'm a small \"indie\" dev. Here's what I use. \n\nUnity - there's a free version and then there's the highly recommended \"Pro\" version. That'll set you back for around $1500 for a permanent license. \n\n3DS Max - For modelling. Pretty essential. This shit will cost you around $4000+. Oft.\n\nPhotoshop - Absolutely essential. Another $500.\n\nPremiere - For those promos you know? Another $500-ish. \n\nFL Studio - To make sexy ass music. That's around $100. It's the plugins that will fuck your wallet though.\n\nPlatform licenses - Oh dear. Around $100 for an Apple publishing license per year. $25 for a Google Play license. Around $75 for a Steam Greenlight license I think? Console publishing costs considerably more... I won't be touching that for a while. \n\nThen there's the other stuff.\n\nMarketing - For AAA publishers? They have millions to splash out on TV spots, billboards, online banners. For Indie devs? Ehh... word of mouth, obnoxious video postings on forums, conventions etc. It's hard to get off the ground. I made the mistake of not advertising my Kickstarter and it failed miserably. Even with the small goal. Don't make that mistake!\n\nLabour - That's right. You have to pay the lovely people who are working on your game. The rates vary depending on position/company etc. And it's common for developers to pay for outsourcing. No point in hiring an animator/actor/whatever for the whole development process when they might not be utilised the entire time right? \n\nUpkeep - Doesn't matter if you're working in a small or large office space. You've got to pay them bills.\n\nIt's fucking insane. ", "The game business model is one of a long period of high fixed costs, preceded by a huge spurt of revenue and minimal costs thereafter. \n\nThe fixed cost period can last 1-3 years and typical costs include employees (in-house and outsourced), software kits and subscriptions, hardware, supplies, rent on office space, license/registration fees, legal fees, and the list goes on. And then there are advertising/marketing costs, which are usually substantial relative to the rest of the budget. The biggest cost is probably labor. \n\nA lot of indie developers have cleverly offer \"alpha\" and \"beta\" stage pre-releases as a way to generate cash flow to fund the fixed cost stage of development. \n\nWhen the game finally is released, most revenues will occur within the first few months, so there is this huge spurt, and then there will be a geometrically declining sales curve from there. There is a huge amount of \"execution risk\" around the time of release. Any bad bit of press can fuck things up. Someone releasing a similar game at the same time can fuck things up. Poor execution on the marketing/advertising can fuck things up. Or if your game just isn't well received by gamers, it can fall through as well. \n\nGames are a volatile business. Nintendo is notable for carrying a HUGE amount of cash on their balance sheet. They could totally screw up a whole console cycle, make no money, and still have enough in the bank to survive until the next console cycle. That is a sign of just how tough the business can be in terms of that execution risk. ", "This sums it up quite well: \"Eidos president Ian Livingstone said one developer spent two years programming Batman's cape, using over 700 animations and sound effects to make it move realistically\"", "I'm a software developer. I make around $60/hr, and I'm around the middle of the pay bracket for what I do. If you want _real_ talent, you tend to pay more. If you don't care if you've got empowered script kiddies, you tend to pay less.\n\nGame development often takes a small team of developers - people specialized in physics software, interaction design and implementation, gameplay, logical design patterns, and an architect. Call it five skilled people at a minimum for an A class game.\n\nIt also takes designers - most at least as well-paid as I am. Sounds, graphics, characters, etc. Call it another five humans.\n\nIf the game is capped at 1000 hours of work (about 6 months), that's at least $600,000 to develop a game - not counting what you pay for bean counters and marketing.\n\nNow, you _can_ make a game with one person and a few weeks - it might actually be fun, too - but if you want end-to-end quality, top-notch graphics, deep storyline, etc - you're getting into the area of $1e5-7, depending on who's willing to work for what, how long it takes, and how ambitious the game is.", "Because everyone that works on the project is going to be paid full-time money. Money that is used to live one's life for up to, or at least 1 full year. Tis a lot of money for even just one person.", "It's expensive to keep a person alive who has a very high skill set. If you're an indie game developer such as myself you have to make sure you can eat and live. Since you can either spend a small amount of time making a simple game that could go unnoticed or you could make a bigger one and run the risk of running out of money. \n\nKickstarters ask for a lot of money since it will go toward living expense for the developers to work on a game full time and for the tools needed. If you're on a Wii U (I have a dev license for this but not the other consoles) you need to pay for the dev hardware which costs a few thousand dollars. \n\nSo it either costs money or time which both are a premium.", "As a dev who is about to post up a kickstarter, here's how we determined the amount we're going to ask for:\n\n1) living expenses for the team for long enough to start selling the game\n\n2) External contractor bills\n\n2a) sound studio\n\n2b) voice acting\n\n2c) character modeler\n\n(there would be a 2d for the writer, but we've already paid him in full out of pocket)\n\n3) software! It's really easy to get up over $5,000 per person for basic programs and tools. \n\n4) Advertising. We try to get the most out of small amounts of money by going to conventions, but it's still several thousand dollars per con to get a table and present for a couple days.\n\n5) hardware. We're mostly using our personal computers for development, but we're having to buy Oculus dev kits, a mac (so we can release on macs & iphones), laptops to present on, a mic for recording quick stuff we don't want to send to the contractors, etc. We also have to rent dev kits for consoles and handhelds.", "Devpacks are expensive and stupid project managers are even more expensive.", "Here's an great example I read a while back giving an idea of how complicated rather simple things in game design can become.\nSource: [Liz England](_URL_0_)\n\nThe Door Problem\n\nI like to describe my job in terms of “The Door Problem”.\n\nPremise: You are making a game.\n\nAre there doors in your game?\nCan the player open them?\nCan the player open every door in the game?\nOr are some doors for decoration?\nHow does the player know the difference?\nAre doors you can open green and ones you can’t red? Is there trash piled up in front of doors you can’t use? Did you just remove the doorknobs and call it a day?\nCan doors be locked and unlocked?\nWhat tells a player a door is locked and will open, as opposed to a door that they will never open?\nDoes a player know how to unlock a door? Do they need a key? To hack a console? To solve a puzzle? To wait until a story moment passes?\nAre there doors that can open but the player can never enter them?\nWhere do enemies come from? Do they run in from doors? Do those doors lock afterwards?\nHow does the player open a door? Do they just walk up to it and it slides open? Does it swing open? Does the player have to press a button to open it?\nDo doors lock behind the player?\nWhat happens if there are two players? Does it only lock after both players pass through the door?\nWhat if the level is REALLY BIG and can’t all exist at the same time? If one player stays behind, the floor might disappear from under them. What do you do?\nDo you stop one player from progressing any further until both are together in the same room?\nDo you teleport the player that stayed behind?\nWhat size is a door?\nDoes it have to be big enough for a player to get through?\nWhat about co-op players? What if player 1 is standing in the doorway – does that block player 2?\nWhat about allies following you? How many of them need to get through the door without getting stuck?\nWhat about enemies? Do mini-bosses that are larger than a person also need to fit through the door?\nIt’s a pretty classic design problem. SOMEONE has to solve The Door Problem, and that someone is a designer.\n\nThe Other Door Problems\n\nTo help people understand the role breakdowns at a big company, I sometimes go into how other people deal with doors.\n\n* Creative Director: “Yes, we definitely need doors in this game.”\n* Project Manager: “I’ll put time on the schedule for people to make doors.”\n* Designer: “I wrote a doc explaining what we need doors to do.”\n* Concept Artist: “I made some gorgeous paintings of doors.”\n* Art Director: “This third painting is exactly the style of doors we need.”\n* Environment Artist: “I took this painting of a door and made it into an object in the game.”\n* Animator: “I made the door open and close.”\n* Sound Designer: “I made the sounds the door creates when it opens and closes.”\n* Audio Engineer: “The sound of the door opening and closing will change based on where the player is and what d irection they are facing.”\n* Composer: “I created a theme song for the door.”\n* FX Artist: “I added some cool sparks to the door when it opens.”\n* Writer: “When the door opens, the player will say, ‘Hey look! The door opened!’ “\n* Lighter: “There is a bright red light over the door when it’s locked, and a green one when it’s opened.”\n* Legal: “The environment artist put a Starbucks logo on the door. You need to remove that if you don’t want to be sued.”\n* Character Artist: “I don’t really care about this door until it can start wearing hats.”\n* Gameplay Programmer: “This door asset now opens and closes based on proximity to the player. It can also be locked and unlocked through script.”\n* AI Programmer: “Enemies and allies now know if a door is there and whether they can go through it.”\n* Network Programmer: “Do all the players need to see the door open at the same time?”\n* Release Engineer: “You need to get your doors in by 3pm if you want them on the disk.”\n* Core Engine Programmer: “I have optimized the code to allow up to 1024 doors in the game.”\n* Tools Programmer: “I made it even easier for you to place doors.”\n* Level Designer: “I put the door in my level and locked it. After an event, I unlocked it.”\n* UI Designer: “There’s now an objective marker on the door, and it has its own icon on the map.”\n* Combat Designer: “Enemies will spawn behind doors, and lay cover fire as their allies enter the room. Unless the player is looking inside the door in which case they will spawn behind a different door.”\n* Systems Designer: “A level 4 player earns 148xp for opening this door at the cost of 3 gold.”\n* Monetization Designer: “We could charge the player $.99 to open the door now, or wait 24 hours for it to open automatically.”\n* QA Tester: “I walked to the door. I ran to the door. I jumped at the door. I stood in the doorway until it closed. I saved and reloaded and walked to the door. I died and reloaded then walked to the door. I threw grenades at the door.”\n* UX / Usability Researcher: “I found some people on Craigslist to go through the door so we could see what problems crop up.”\n* Localization: “Door. Puerta. Porta. Porte. Tür. Dør. Deur. Drzwi. Drws. 문”\n* Producer: “Do we need to give everyone those doors or can we save them for a pre-order bonus?”\n* Publisher: “Those doors are really going to help this game stand out during the fall line-up.”\n* CEO: “I want you all to know how much I appreciate the time and effort put into making those doors.”\n* PR: “To all our fans, you’re going to go crazy over our next reveal #gamedev #doors #nextgen #retweet”\n* Community Manager: “I let the fans know that their concerns about doors will be addressed in the upcoming patch.”\n* Customer Support: “A player contacted us, confused about doors. I gave them detailed instructions on how to use them.”\n* Player: “I totally didn’t even notice a door there.”\n\nOne of the reasons I like this example is because it’s so mundane. There’s an impression that game design is flashy and cool and about crazy ideas and fun all the time. But when I start off with, “Let me tell you about doors…” it cuts straight to the everyday practical considerations.\n", "Manpower is expensive, video games take manpower.\n\nLet's say one of your people $50,000 a year on average. Just five of them cost you $250,000 for the year. That's without any overhead for rent, software licenses (which certainly aren't cheap), their computers, dev kits, ect. 5 people is a super small indie team.", "I'm currently in the process of starting up a small indie games company in Australia, there are a lot of costs and skills that go into making a game, from the people who write the software we use, to contractors that we have to hire to fill the gaps. \n\nTo give some idea of what we are spending on our first game below is a list that is by no means comprehensive.\n\nWe need 3 copies of unity for our programmers, which is about $1,500 each.\n \nThe art program we we're taught in costs around $6,000 for one year per artist so we have had to go with less desirable options. \n\nWe don't have anyone who knows sound in the team so we are hiring a musician and will probably have to hire a sound engineer as well. \n\nPaying a marketing firm will cost us about $3,000 per month.\n\nLuckily we are all studying in a specialized business course that helps companies like ours get off the ground and included in the fees are things like internet and office space, as well as the chance to go to some conventions and get our game out there, but that course costs about $20,000 each. \n\nIn Australia we all get some money while we study which is what we are living off for now but next year we will be on our own and to make ends meet we will need a minimum of $12,000 per person, plus the costs of office space if we don't want to be working out of a garage (which may well happen).\n\nThe dynamic of video game development has changed drastically in the past few decades, where before a team could get a publisher to cover the cost of development once they had a cool demo to show, nowadays publishers wont touch a game until it is almost finished and put some of their marketing power behind it for a large percentage of the money that the games make.\n\nBut with all that in mind we are all together taking a shot at the career that we want, making games that express what we want. So even if I end up dirt poor in a gutter somewhere at least I'll have tried." ] }

how does the theory of evolution explain the development of adaptations, the intermediate stages of which are unlikely to be advantageous to the organism (e.g., winged flight)?
For some adaptations, like winged flight, it seems like the end "product" (wings/body type capable of flight) is beneficial to the organism but the millions of generations it would have taken to get to that end product would have been disadvantageous. Put another way, would only partially developed wings provide any evolutionary advantage, such that the trait continued to develop? Alternatively, if the wings were instead the result of a sudden, spontaneous mutation, how would the animal have known how to use them effectively? Either scenario seems unlikely, but I assume there is a well accepted answer to the question.

But \"slightly better\" is a term that contains a universe of possibilities.\n\nFor example, feathers evolved (probably) as a way for an animal to radiate heat. They became better and better heat radiators and coincidentally also became something that could help an animal glide through the air (or fall more slowly). At some point the \"wing\" qualities of feathers became more important than the \"radiate heat\" qualities, but without that first rationale feathers wouldn't have evolved.\n\nAlmost every biological system follows this pattern. The changing system produces a variety of subtlety and incrementally better changes to the base system, and at some point a new potential capability becomes possible and then evolution can act on that potential too. Evolution doesn't work by targeting an end state, it just works by selecting a slightly better version of whatever systems are currently available and sometimes those changes produce surprising new capabilities.", "The likely intermediate step was useful either for gliding (such as a flying squirrel), or as an extended jump (like a domestic chicken). Both of those are useful for quick bursts when fleeing from a predator. From there longer, more controlled, and powered flight are all beneficial improvements, but as pointed out there are examples of living creatures today that survive with pseudo-flight.", "The trait continued to develop because it was still advantageous, even though it was not as good as the current wing. It was advantageous all the way, that's why the trait survived.\n\nHaving wings that can help you fly 10 kilometers is worse than having winds that can help you fly 100 kilometers, but it is still an advantage. And if you go back in time even more, you might be able to fly only 1 kilometer, which is worse, but still better than not being able to fly.\n\nAnd if we go back even more, that animal might only have had some skin between its legs [like this](_URL_0_). It wouldn't be able to exactly *fly*, but it could still glide for quite a distance if it jumps from a tall tree.\n\nGoing back even more, those flaps would have been smaller.

For example, many polls undersample young people, so giving more weight to the young people who did respond (considering their proportion of the population) corrects this bias.\n\nThis is one reason that it is very important to check a poll's methodology before considering the results. A poll that is poorly conducted is worthless. Since it is political polling season, it is worth noting that even the best of polls are bad indicators of how people will vote--people say one thing, but when they are in the voting booth it is often quite something else. Hence why so many in the Republican field are hoping for a primary win despite polling low.", "A scientific poll will get a lot of demographic information to ensure that the poll is accurate.

At what level of quality?\n\nJust outside my neighborhood there is a row of restaurants. I learned a few years back that they offer very different wages. One of them, the low-end chain, offers minimum wage for most workers. One offers about $1.50 over minimum wage. Another -- more of a premium sit-down restaurant than fast food -- offers about $4 over minimum wage for cooks but requires a few years of work experience.\n\nWages and jobs are not all the same. \n\nUsually it works with supply and demand, and with turnover. If you are looking at jobs that are filled in bulk requiring zero skill, anything from a call center front lines to the person stocking shelves at a big box store, anybody can do those jobs, and there is an enormous list of people *with no skills* or people *wanting a menial but easy job* willing to accept those jobs for low wage.\n\nWhen a company requires a little more experience the market is different. Re-heating meat patties in a line is unskilled labor and is increasingly being replaced by machines, the wage is as low as the market or law allows. The moment it becomes cheaper to bring in a robot rather than pay an unskilled worker, [robot burger cooks like these will be installed.](_URL_0_) This is already happening in cities where labor is more expensive. A short-order cook who can turn out everything, grilled top sirloin to salads and soups to pizzas and sandwiches, requires more skill and experience, and thus can generally negotiate a higher wage. But even those will be replaced with robots [when they can do the job more reliably and cheaply.](_URL_1_)\n\n" ] }

It goes in the bank and looks like a lot, so you pay the rent, utilities, put food and alcohol in the fridge, maybe go out a bit. By the end of the 3rd week, there is not much left in the bank. \n\nThat's ok, payday is in a week, all things are cool, just tighten the belt a little. THEN, your car breaks down, and you need it to get to work. So what do you do, max the credit card out (remember the interest/overdraft) , hit the oldies for a loan? Which they give you provided it is paid back as soon as you get paid. \n\nAnyway, the 1st comes around again, you pay the money back, but, now are a little short for this month, because you don't have the same amount of income to meet expenses that you had last month. \n\nEdit1: And so the cycle continues, until either your income improves or you go broke.\n\nHope this was reasonably understandable.\n\nEdit2: Also end of financial year can provide a totally different scenario.\n\n\n\n\n\n" ] }

planetary orbits within our solar system...
So I was thinking about every planet's orbit in our solar system. They're all elliptical, because they are conic sections, because of differential calculus. So sayeth Sir Isaac Newton, as evidenced by Neil Degrasse Tyson in his now famous "We've got a badass here" pose. In every diagram I've seen, the planets are always aligned on one axis, let's call it the x-axis. Is that their alignment in real life? I always imagined space was more chaotic and that planets would orbit the sun wherever, within the 360* possible (or more, depending on how 3D we'll take this model), some on a y-axis, and some on a slope of the x/y axis. Is the model wrong and just showing things for simplicity, and the planets really are orbiting all over (like the lines drawn around an atom) or did the planets really align nearly perfectly. Either way: what is the current theory for why this happened? Admittedly, if the planetary orbits are actually all over, random chance is a pretty good explanation.

This is good for British politics as a whole as it will result in more left-right debate, as opposed to fighting over the same ground and every party being much the same, as has been the standard in modern times. Having parties that oppose each other ideologically can only be good for politics as it offers the voters a clear and distinctive choice, other than policies only differing slightly. I feel that it will make politics more engaging and will interest would be voters, so good for British politics.\n\nHowever on the flip-side of that I don't think it necessarily a good thing for Labour. As mentioned previously Corbyn is very left wing, think Sanders and just keep going left, and while being exciting he doesn't offer Labour the stability they need after such a heavy loss. He is strong in his conviction and has been saying the same things for many years, but he is very easy to attack, from a Tory point of view. For perspective his predecessor was nicknamed Red Ed, for his supposedly left wing views. Now Milliband was far from being left wing, but he was still perceived that way, and was attacked for. So just imagine what opposition could to do someone with actually left wing credentials. I think when it comes down to it he is just to left and too divisive a figure to win an election. In fact the last time Labour went this left was 1983, and their manifesto that years was nicknamed 'The longest suicide note in history', by a Labour MP, and I feel that unless he tones down his ideology this is the way, Labour are heading.\n\nTL:DR: Good for politics, more right-left debate, bad for Labour, too left and to polarising to win election ", "Its compleatly unpredictable, most press sources seem to believe that he is unelectable but they don't really know that.

When you start nit picking the line between science and engineering can become blurry, but generally scientists seek to increase knowledge for the sake of knowledge whereas engineers take knowledge and use it to do things. For most branches of the hard sciences, there is a corresponding branch of engineering. Electrical engineers understand electromagnetics to design power systems, motors, computers, etc. mechanical engineers understand materials science, classical physics, fluids, etc to design pretty much everything. A very clean example of the line is a chemist versus a chemical engineer. (Very generally) A chemist works in a small lab trying to figure out how to synthesize some new molecule or how to do it better; a chemical engineer designs a system to take that process and scale it up to industrial production quantities.\n\nThe jobs of engineers vary greatly too. Engineers oversee the entire process of a product’s lifecycle from conceptual design to disposal. Some engineers design the thing, some oversee manufacturing, some oversee operation of complex machinery/systems, some do research and development. Pretty much everything man made thing you have ever seen or touched was designed by an engineer and manufactured under the supervision of an engineer." ] }

Once the firing pin strikes the primer and ignites the powder, the bullet leaves the brass casing and enters the [\"lands and grooves\"](_URL_2_) which are the start of the actual barrel.\n\nOnce the bullet is in the lands and grooves, it starts twisting thanks to [\"rifling\"](_URL_3_) in the barrel that causes the bullet to twist. This keeps the bullet stable in the air.\n\nBut back to the brass casing. Once the bullet leaves the brass and is in the barrel, a couple of different things can happen. The main idea is that the [\"extractor\"](_URL_1_) is grabbing on to the rim of the casing (see [this picture](_URL_5_)). Once the bolt carrier/bolt is charged back, it pulls the casing with it thanks to the rim of the casing. Once the bolt is all the way back, the brass casing will now fly out of the breech, because the extractor is only gripping on to one side of the casing. Imagine pulling a book off the edge of the table by grabbing it on the edge that is hanging off the table. The book is going to fly out towards the edge that you pulled. Same concept for a casing leaving the breech.\n\nBut what causes the bolt to fly back once the gun is fired? Either 1) inertia or 2) gas blow-back. Some guns simply use the force of the casing/round flying back (think of Newton's laws of motion) to bring back the bolt, and some guns (such as the AK-47 and AR-15 platforms use the gas that is leaving the barrel to push back in a tube and move the bolt. See [this animation](_URL_4_).\n\nHope that helps!\n\nEdit: some words", "I'd like to add that brass is a popular material for cartridge casings in part because of its lubricity; that is, it has a slight inherent slipperiness, particularly relative to the steel of the chamber.", "This question has been answered already but there is a third mode of ejection I'll mention.\n\nIt isn't common for obvious reasons, but some small pistols use *the jetfire principle* which is akin to a blowback system. But there *is no extractor.* Nothing hooks the cartridge out of the chamber. But brass expands when it is fired, this is called *fire-forming* and the change in dimension is enough to loosen it. The backward pressure of the detonating cartridge is enough to eject the brass when the slide travels to the rear.\n\nBut this is relying on the bullets to do it, and sometimes it can fail. I have a Beretta 21A, similar to the [Beretta Jetfire](_URL_0_) which uses this sytem. I actually really like it, and it does work, but it can fail.", "When you're shooting a revolver the casing never enters the barrel, it stays within the cylinder. To extract the cartridge you have to push the extractor rod into the cylinder which forces the shell out. The shells are kinda stuck, you have to apply some force to get them out. They won't all just fall out if you invert the cylinder the way they do in videogames. " ] }

why didn't the federal government give bailout money to home owners instead of the banks?
Why didn't the federal government give bailout money directly to homeowners in pre foreclosure, with stipulation that money must be used towards their mortgage? Wouldn't this have ultimately achieved the same result (bank getting the bailout money) without so many people being foreclosed on?

If they bailed out the people instead, chances are the people would have the tendency to just see it as free money and not do anything useful with it. \n\nNow, if they gave money to stop their foreclosure instead, it would have probably cost a lot of money. The bail out most likely just covered the banks' losses. But to keep the houses, it would have cost a lot more.", "The realistic answer to this is that the sum of money used in bank bail outs was less than all the money needed to deal with the foreclosures.\n\nNow obviously you would argue \"well why didn't they just save as many foreclosures as they could with that money, the banks get it in the end\". \n\nTo which the answer is simply its overt complexity and the fact it would cost more money to give out that much money, track that money, make sure people actually spent it on foreclosures, etc. Not only this by the time the banks got it there would be fees and such of there own further reducing this sum of money. \n\nThen there is the more direct concern that keeping major lending/financial institutions up and going helped keep other businesses not directly related up and going. If lenders are functional a business temporarily in the red can get a loan and recover, as can others. The direct \"bail out\" also allowed the banks to have more capital to directly lend in these situations aswell. \n\nHypothetically in a perfect world what you said could be done, but we arn't in a perfect world the very fact the foreclosures and recession happened more than proves this. Instead of a very complex and much more expensive route that saved some homeowners, they opted for the direct approach that best kept society going which was also much cheaper. ", "The government can regulate how the banks use the bailout money; they cannot regulate how individuals would use the funds. A lot of Americans would not use the money for its intended purpose which would essentially compound the problem.", "Serious answer: Because the banker bailout mastermind Henry Paulson was CEO of international bank Goldman Sachs, immediately before being appointed Treasury Secretary. Goldman Sachs received $10B in the bailout. Paulson was worth $700M at the time. Homeowners not being able to pay a mortgage were not and are not in his sphere of influence.", "The government did \"bail out\" homeowners, but not by handing them money (which would be impossible to account for). \n\nUnder a government program, I was able to refinance my mortgage despite being moderately underwater. My monthly payments went down 25%. My interest rate is among the lowest in US history, which was also due to government action. Around the same time, there were huge government incentives for first time home buyers. ", "Imagine your allowance was a million dollars. That's pretty nice, right? Eventually you hire other people to do your chores and you just keep the rest.\n\nAfter some time passes you find that you have more money than you can spend for the rest of your life. In fact, you have more money than all your friends can spend in their lives too. \n\nThis would be great for a few decades but eventually you may wonder \"What's next?\" Well, some other folks thought that too. They came up with a way to turn their money in to power and influence. \n\nThey accomplished this by becoming a bank. They convinced politicians to make their bank the official unofficial bank of the United States. They're allowed to create and destroy US currency any time they would like to give loans to people.\n\nOf course, some people were wise to their ways. They did what they could to avoid borrowing money and going in to debt. The bank didn't like that very much at all. \n\nOver time, the rottenness of this bank creeped in to other banks. This central bank gobbled them up, replacing those banks with copies of itself that looked like the old bank. This led to an entire country of people - who were one time the wealthiest, most prosperous nation in the entire world, becoming slaves to the central bank. If you needed to borrow money, it came from one bank. If you needed a savings account, the rates come from one bank. \n\nThese people weren't slaves like you are taught about in school. This form of slavery is much sneakier. You see, the banks don't care about your religion or skin color. They don't care what you do for a living, they don't care who you marry or where you make your home. So long as you forfeit to them a portion of your wages.\n\nThey accomplished their evil goal through their government partnership. Through government, the bank is able to move from one part of the market to the next. It pumps up the market with huge lines of credit, people borrow money they cannot afford to repay, soon that entire section of the economy is relying on the flow of money to continue operating their businesses.\n\nAnd then the bank stops the money flow. The bubble pops. Businesses stop working. People lose their jobs. No one repay the bank.\n\nThe federal government derives most of its power from the military and from the banking system. Without the ability to print money on a whim the US government would have to raise taxes (Printing money is effectively taxation but it is sneakier). \n\nWhen the government paid the banks it was securing it's ability to do whatever it wants with the money. \n\nTax payers - > Pay taxes to government\n\nTax payers - > Owe money to banks\n\nTax Payers cannot pay.\n\nGovernment gives tax payer money to the banks.\n\nBanks say \"Hah, even though this is the tax payers money we aren't forgiving tax payer debts\"\n\nGovernment says \"As long as we can keep printing!\"\n\n**TLDR: Federal Reserve**", "This is a two parter: \n1. A big part of the reason for the bailout was to unfreeze credit markets. Banks weren't lending because they needed the cash to replace losses from nearly worthless assets backed by junk mortgages. Businesses need access to credit to function so the banks got money with the idea that they'd actually lend it out. That was an immediate problem which needed to be addressed somehow or we would have had a cascade of failing businesses. \n2. You might be asking, \"Then why didn't the government offer to make mortgage payments which would go to the banks eventually anyway and kill two birds with one stone?\" Most of the mortgages weren't held by the banks. They serviced the loans which means they handled the administrative activities but most of those mortgage backed securities were actually owned by institutional investors (pension funds, some exchange traded funds, etc.). \n\nNow for commentary: \nAnother plan was for tax payers to buy out failing banks so we'd get some equity out of the deal and get our money back when we sold it back off at something like an IPO but somebody yelled \"SOCALISM!\" so we couldn't do that. Iceland did and they didn't burst into flames or anything. \n\nPart of the reason this all got so out of hand was that banks gave mortgages to people they knew couldn't afford them because they were taking fees origination fees and selling the actual notes off to someone else. They didn't have that much skin in the game until it became obvious that these were increasingly worthless and they couldn't sell them anymore. When the scam was running well they convinced crooked ratings agencies to give inflated grades to their junk securities made of bad mortgage bundles and used those grades to buy insurance backed by pretty much nothing (AIG).", "Because banks own both political parties, and it's always easier for politicians to protect the status-quo than to come up with an innovative, just, solution that might rock the boat.", "It was a loan. And its all paid back with interest, for the record.\n\n", "Like they did in Iceland and they did very well. Also arrested the bankers. So in my opinion the bankers had many good friends in politics!\nAnd isn't it funny that the money transferred offshore is pretty much the same amount the taxpayer paid to save the banks? And why did the managers, who allowed this shit got boni, but the homeowners the boot? \nAnd after being bailed out the banks start crying \"get out of my business government\" what's wrong with this picture?\nHonestly America was founded as protest against the (British) government, but now? No sound against government control and suppression (patriot act) not a peep against the banks robbing everybody and getting tax funding to do so. The forefathers would turn in their graves, if they know!", "The crash wasn't directly caused by people foreclosing, it was caused by the banks crashing AFTER so many mortgages were foreclosed leaving them with a bunch of properties which became toxic when the real estate bubble burst.", "The government did help out homeowners as well. When the government took control for Fannie Mae and Freddie Mac they introduced the Home Affordable Refinance Program (HARP). This allowed home owners that had a mortgage that was backed by Fannie and Freddie to refinance their mortgage to a significantly lower interest rate no matter their equity position in their home. Most of these refinances were done without even having an appraisal done. I will also point out that this program allowed people that had damaged or not perfect credit to get a lower rate that they would not normally qualify for. \n\nThe government also helped VA and FHA home owners, since those are government backed loans as well, with what is called a VA or FHA streamline refinance. These programs allowed people to refinance as well without have to do an appraisal as well as not having to credit qualify. That means that the banks didn't even pull their credit and offered them a lower interest rate. \n\nAside from these programs the government has been buying bonds and mortgage backed securities to keep the interest rate down for the public to be able to refinance of purchase affordable housing during the recession. \n\nTl;dr: HARP program and VA & FHA government refinance program helped the general public refinance to lower rates.

The biggest reason: We were in a liquidity crisis, where banks need cash to meet obligations, or they are at risk of failing. Giving that money to homeowners to pay the banks through their mortgage would get the money into the system very, very slowly; mortgages are small slices of payments over 30 years. \n\nThe banks were ready to fail in weeks, not years, and a failing bank would have a cascading effect on the financial system.

People were starting to purchase homes they couldn't realistically afford. In return, the mortgage payments people owed on their homes were over half their salary. The recommendation is 1/3 of their salary. \n\n**What went wrong?**\n\nMortgage companies were stupid enough to allow people to purchase these homes. For example, at the time the recession happened I was approved to buy a home for $300,000 when my salary was only $30,000/yr. Really bad idea. Eventually, it caught up to the mortgage companies and they had more debt than income. \n\n**Then what?**\n\nAIG amongst many other large companies started declaring bankruptcy. Some took government loans and went through a restructure, taking advantage of bankruptcy protection laws.\n\nLaws were placed to have more strict regulations, accounting practices, and loaning practices. \n\n**The bailout - the answer to your question**\n\nThe idea behind giving people money, not just home owners, was to jumpstart the economy. People would spend this money on electronics, food, or anything to help prevent businesses shutting down.\n\nGiving money to people who were already foreclosing on a home would've only helped them for that one payment. Then what? They're in the same situation. \n\nThe plan, however, somewhat backfired, but not entirely.

You can see this from amount of verification that is required now for purchase/refinance a mortgage.\n\n * There is no way to accurately measure how much money is needed NOW, over next few years and over all as home owners will overtime come out and make requests for bailout.\n\n * There is no way to qualify a borrower; can you bailout a guy who's 50 LTV on a $100k mortgage, or 110 LTV on a 110k mortgage, or 95 LTV on a $1,000,000 mortgage? What about credit scores, other assets, etc. etc. \n\n * There is no current system in place to qualify a borrower for bailout; a system needs to be developed, tested, implemented, etc. This makes it possible for lots of risk.\n\nThere are other points to consider but you get the point. It takes a lot of housekeeping to qualify borrowers.\n\nOn the other hand, if you bailout banks following happen:\n\n * Banks already have a system in place to qualify/screen borrowers income, assets, mortgage, that can be re-deployed to qualify if a borrower requires bailout.\n\n * Banks report net income on expenses (loss) and profit. If everyones paying bills on time, expenses are lower, profits are higher. If more and more borrowers need bailout, banks will report higher losses and lesser profit. Thereby you can easily calculate how much money is required for bailout. I say easily because the bailout is in hundreds of billions of dollars over millions of borrowers. \n\n * Ultimately banks are setup for peoples benefits. Why throw out people from their homes leaving lower house values when you can keep people in their homes, let them have a roof and also maintain the asset owned by banks. Banks will overtime get through the number of bailouts in a semi-manageable manner.\n", "look at all these people taking loans that they cannot afford, setting themselves up for financial ruin if the slightest thing goes wrong. let's give them money, they sure seem to know how to handle it. ", "Looks like a lot of people don't know jack about the financial system in this thread. \n\nGiving bailout money was not free money- it came with the stipulation of either part government ownership of the organization I do believe or it was essentially a loan that had to be paid back. Over half of the loans paid out have been paid back( 384B dollars out of 609B). Thanks to gaining equity in some companies the government made over 200 billion dollars in dividends in those companies. All in all the government has actually profited 12 billion dollars from the bailout. \n\nThat is something they could have never done giving money to homeowners. Additionally the money to banks was necessary because our entire capitalistic economy thrives at the present time through a delicate, intricate, and powerful shadow banking system in which assets and security are traded in enormous amounts not only to create profit but to create liquidity and leverage in the system such that everyone these days can get a loan.\n\n If they didn't bailout a lot of these mortgage-backed security holding banks, the markets would have essentially froze as credit lines were stopped due to risk factors being too high. This would cause a domino effect through the markets that would essentially create a new great depression. Paying mortgage holders instead sounds good but the system would still have collapsed as 1) The size of the mortgage market would have made the bailout of 600 billion dollars a drop in the bucket. Outstanding mortgages in America in 2008 were over 10 trillion dollars in value and in the same year over 9% of mortgages in the U.S. were delinquent and failing. So right there over 900 billion dollars needed to fill that gap. At the banking level, money gets multiplied thanks to things like fractional reserve banking and the fact money can be moved rapidly and easily through different assets where it is needed using the shadow-banking intermediaries so the 600b the government dolled out had a stronger net effect than paying out the 600b of the 900b+ mortgages that were default. 2) paying out the mortgages was a much more complex issue with a lot more record keeping and needed the government to directly pay the mortgage holders because people have a habit of spending money poorly when it arrives in a lump sum(see: tax returns). \n\nWe are not Iceland or a smaller country, and pinning which executives in an organization knowingly took advantages in the credit loopholes we have in the U.S. is nigh impossible. We don't convict men who we can't find guilty in this country so charging the bankers with this probably would not have stuck. I wouldn't have minded seeing the VPs and CEOs of some of the most guilty banks put on trial and possibly convicted for their organizations doings though. But that would have only increased the instability of the country and we have a system literally thousands of times more complex and bigger than Icelands, meaning it's not so simple as throwing a few bankers in jail. I do think they should have been restricted in gifting themselves bonuses and whatnot but obviously the gov't wasn't interested in pissing off too many folks on Wall St. and the relative money involved was nothing compared to the size of the whole ordeal. \n\nThere's a lot more to it and this isn't exactly right but it should be in the ballpark. Bottom line is people criticizing this event who haven't bothered to study its details aren't much different than creationists who criticize evolution. You never have put the time in to understand and you see it in a way most folks in finance do not yet they are the ones who understand it, at least better than the layman. \n\nTLDR: the Bailout has actually been paid back with profit, something paying out the the populace could never achieve. On top of that there was more mortgage debt by over 33% than was paid out to the banks so you can't go and just randomly pay off 66% of mortgage defaults and leave the others to deal with their misfortune. ", "Home owners would have spent it on cars, drugs & women. ", "OP, there are going to be a lot of explanations informed by what the masters of spin in DC and in Wall Street put out for the rest of us to squabble over.\n\nIf you want an actual explanation, read Neil Barofsky's \"Bailout.\" He was the Special Inspector General for TARP (one of the bailout programs), and actually a reasonably unbiased outsider. The book is actually a great read: Barofsky develops it like a narrative, with a storyline, character development, etc.\n\nI hope you get to this comment!", "I don't know. \n\nBut to give an example of another nation bailing out its citizens: Back in 99', Japan gave its qualifying citizens an equivalent to $200 (20x$10 notes) in what was the equivalent to gift cards to spend in stimulating the local economy. \nThe gift cards were regional, so you couldn't use it outside your local area, and no change was given so it couldn't be converted to cash, and it encouraged spending more than the $200 amount. \n\nMy mom bought it off me (she didn't qualify) $ for $ so she could use it for groceries, and I put it away in my savings account. I was 15 at the time. ", "Because the people that make those decisions have a much closer and more intimate connection with people on the banking end than people on the middle-class-homeowner end.", "Some have had a go at answering this question but I don't think anyone has hit the nail on the head. I shall give it a shot\n\nIn actual fact the government did think about doing this, bailing out the home-owners instead of the banks. However, there are number of problems that they ran into that made it impractical at best.\n\n1. **Complexity.** Who gets the bailout, do people who took NINJA (No Income No Job or Asssets) get help? Do people who took out a mortgage for a second home get a mortgage? People who lost their job indirectly because of the crisis and fell behind on their mortgage do they get hope? Was there fraud sure, but a lot of people from bank CEO's, to loan originators, to the people who got mortgages and then foreclosed on made a lot of stupid decisions. The government would have to decide who deserved to be bailed out and who didn't (a decision that is potentially politically explosive) and how much help they would get.\n\n1. **Time.** This was a fast moving crisis, there was no time to put together the type of legislation and then agency action that a mortgage bailout program would have necessitated. Remember how long it took to get the stimulus money out the door, and that was fast by government standards.\n\n1. **The crisis was way bigger than mortgages**. It may have started there but by the peak of the crisis the global economy was at risk. Credit is the oil that lubricates the modern global economy, almost every corporation or company has debt. From a small business with a credit card or small credit line, to the biggest companies like Apple or Microsoft who have tonnes of cash. Most companies do not hold that much cash on hand, it doesn't make sense, why hold cash when you can put it in short term treasuries where it will earn more than the rate of inflation. Consequently most companies take out a short term loan to meet payroll, buy new stock etc they pay it back within days or weeks but it is very handy. At the height of the crisis these credit lines froze, CEO's of blue chip companies like GE were calling the treasury secretary saying they wouldn't be able to meet payroll. Companies big and small around the world were facing the same problem, solvent good companies would have to lay off people or close because of credit freeze brought on by a Mortgage crisis. Something had to be done.\n\nTL:DR - Bailing out homeowners is too complex, would have taken too much time and **The crisis wasn't just a mortgage crisis, its most dangerous aspect was the credit crunch, which put the global economy at risk, would not have been solved by bailing out home-owners**. ", "There are several reasons why they did this.\n\nFirst of all, it's important to understand *why* the government bailed out the banks, and how they did it as well. The TARP program guaranteed large loans to several investment banks (like Goldman or Merril Lynch) and savings & loan banks (like Bank of America). They didnt' do this out of the goodness of their heart, and they didn't do it because they thought those companies were run by \"good guys\". No, they did it because the US and World economy depends on banks. They provide liquidity, and they are an essential part of the engine that drives economic growth: CREDIT. If they hadn't bailed those guys out, then the 5 largest investment banks in the country would have gone to zero. The stock market could've ceased to exist. All that money you've got in your 401-K? Bye bye. And if they hadn't bailed out the savings & loan banks? Well, let me just quote Michael Lewis on that. He put it best in **The Big Short**:\n\n > *When banking stops, credit stops, and when credit stops, trade stops, and when trade stops - well, the city of Chicago only had eight days of chlorine on hand for its water supply. Hospitals ran out of medicine. The entire modern world was premised on the ability to buy now and pay later.*\n\nSo we didn't bail these companies out because we liked them. In fact we didn't like them one bit. They'd stupidly taken **massive, terrifying risks** and abrogated their responsibilities as market makers. Their recklessness gave birth to the phrase *Too Big to Fail*. But at a certain point, that's bygones. Damage done. If they go under, we all go under with them.\n\n_____________________\n\nNow, why didn't we just pay off all the homes? Well keep in mind that when a bank (or the holder of a mortgage-backed bond) forecloses on a house, they don't lose 100% of their investment. They lose about half. After all, the house **is still there**, doing what it's supposed to do, which is to serve as collateral for the loan. They still lose 50 cents on the dollar, due to a variety of reasons (the time the homeowner is making no payments, the cost of the damages as they trash the place on the way out, the cost of selling the house, the loss taken by a motivated seller.) So if you want to bail out the homeowner instead you're immediately talking about **double** the cost.\n\nAlso, the government didn't just **hand** the banks money. I mean, they *kinda* did, but not, strictly speaking. They extended a loan, interest free. Now, when you're talking about *that much money*, an interest free loan is pretty goddamn valuable. You take a loan of, say, 10 billion dollars over one year, interest free, and you put it into US T-Bills, getting, say 1%, and you're still talking about $100 million in risk-free profit. And that's what those investment banks did, really. They just took their interest-free money, put it into safe bonds, and pocketed the interest to pay off their bad investments.\n\nIt's also important to realize that while the these investment banks did take a huge bath on these bad loans, they were only exposed to a tiny fraction of the **total** bad mortgage bonds out there.

But thank GOD the banks were saved. They should have been allowed to fail and the mortgages they had no business giving out should have been absolved. Or better yet, take all that wonderful stimulus money and apply it to my mortgage to help bring me back out from underwater so I can refinance. Get me back to discretionary income levels and I'll spend it on the economy. (IMO) No, instead we just propped back up a bad business model: a housing correction is bound to happen again.", "This thread is just hundreds of people give hundreds of alternative, conflicting answers to OP's question.\n\nCant we just admit that most of us, if not **all of us**, do not know what the hell we are talking about beyond what we're repeating from media and people claiming to be experts? \n\nEconomics may as well be magic. ", "I was not underwater. I worked hard, saved and paid 50% down on my mortgage. ($100,000). Then I was badly injured and couldn't work for 4 years. I have been unable to get hired at a full time job ever since (I am currently 18 months behind on Payments). A judge ordered the insurance settlement from the accident be split between three victims instead of each victim getting a separate settlement. The settlement share wasn't enough to stop foreclosure on my home. I applied for mortgage help through two different government plans. I didn't qualify for either one. The mortgage bailouts were only for the so called \"sub prime\" victims and victims of what was termed mortgage fraud where payments were allegedly mismanaged or misdirected by certain banks. There was no help for those of us who did everything right and got behind through no fault of our own. I sued to gain time but it is only a delaying tactic. I will be homeless in 3 months. I will lose everything I worked so hard for and still no job. ", "The bailout was done to stop a bank run on the major banks. \n\nThe story is, the banks were deregulated in the 90s from having to keep provisions for the loans being made, this allowed for cheaper loans without increasing the inflation rate. This built up into an asset bubble which fed back into the valuation of the banks, this caused exuberant optimism in house prices, leading to lowering of lending standards.\n\nWhen the bubble burst, the balance sheets readjusted, we realised the banks no longer held enough money to stop a bank run. Failstop solution was to bail the banks to stop creditors calling on the bank and collapsing the system.\n\nEven if the mortgages were purchased by the government, the bank run would have still collapsed the system." ] }

how are certain behaviors ingrained in an animal at birth, and it just knows how to do something?
Even we do similar things at birth despite not knowing how to do it. For example, we instinctively reach towards our mother's nipple for food. How is that transferred from a grown animal that has figured that out into its offspring?

If you renamed the photo they would be unable to tell. There's also the exif data which is what your device adds to photos such as when and sometimes where it was taken, whether it was modified, etc. It's not terribly difficult", "There are multiple tools. Reverse searching allows you to find where the photo has been. EXIF data in images allows you to see photo metadata (information about the photo like what camera took the photo). There can also be some social engineering like gathering information you find. It's kind of like putting a puzzle together. \n\nIf I were to find a picture of anon's Facebook profile, I could put it in Google's reverse image search engine and it could link me to anon's Steam account (for example, if he used the same photo) and he could have info of where he lived or other things like that.\n\nDoxing isn't *too* hard.", "Doxing isn't too hard.\n\nIt requires you to have just a general clue or vague information about that person, and then just to know how to search and filter out the noise. \n\nUsually it happens that someone recognises a familiar reference point, around which you are able to work. While it is possible for one person to dox, it is really much easier to let a group of people / hivemind work it out. \n\nThe other thing is that people leave a large unique footprint on the Internet, even if they try to avoid it. By unknowingly releasing such info (even by others, not just that person) it is possible to work it out like a jigsaw puzzle and find out things about them. \n\nPractice makes perfect, and friends make it easier. ", "Because people are completely clueless about:\n\n1) how much data they are willingly giving to web services that they can make public\n\n2) how much those companies track them\n\nAll they need to do is get that data from those companies. Many people say \"I don't have anything to hide\" - until something like that actually happens to them, and *then* they realize just *how much* they care about privacy.", "I've seen a couple of varieties, but the basic skill is the same. Find something connecting the photo to another account. \n\nFirst, you look for \"Metadata\". Metadata is extra stuff other than the primary information in a file. For instance, if a file's primary info is a photo, metadata will be \"EXIF\" data, which typically has things like make/model of camera, date and time photo was taken, etc. \n\nMost cell phones, when you take a picture, will add the GPS coordinates to the photo as well. You take a photo with your phone from home with that enabled? Boom, I can now figure out where you live in minutes. \n\nFortunately, due to a lot of publicity about this, many phones have this option disabled by default now. Still, doesn't hurt to check. \n\nStill, other data buried there might be useful. My camera, for instance, adds a bunch of photo related stuff - make, model, date, time, lens used, shutter speed, ISO, flash settings... but it also adds some copyright stuff. When I first set the camera up, it asked me for a name. That name is tagged onto every image shot under a \"Copyright\" field. In theory that's supposed to make it easier for me to track if people are stealing my images. But since I used my username - sgtkashim - pulling that out of one of my photos and googling it would lead you back to my profile. I usually strip all metadata before I publish a photo. \n\nAlong with metadata, the filename is sometimes useful. If you save a photo *from* facebook, the filename is based on your profile number. A file that hasn't been renamed makes it a cinch to get back to the original profile. \n\nSecond, reverse image search. You can use a service like tineye or similar to see if an image is posted *anywhere else on the internet*. Let's imagine you post an image on your OKCupid profile. You like the picture, so you put it on Facebook too. Reverse image search will find those links. Your facebook profile is usually a gold-mine for find out more about you. \n\nThird, you can look at the photo itself. One of the best I've seen, someone posted a photo of themselves. Behind them, on the table, was an envelope. The photo had enough resolution to zoom in and pull a name address off the envelope. Tada. \n\nFourth, username re-use. Many people use the same username on many many websites. I made the mistake of giving mine to Facebook, for instance. This created a link between the user on the internet, and my real identity. In many cases, simply googling someone's username is enough to find all kinds of things about them. From there you can follow a trail of email addresses and usernames back. \n\n\nActual PERSEC on the net is a hugely difficult thing to do right. \n\n\nThen the question becomes - what do they do with it?\n\nOnce someone has a real-world name, they can make your life very difficult. Studying your facebook profile and available public records stuff, they can often find enough detail to guess your security questions. That gives them access to your email accounts, maybe amazon and netflix. Amazon and Netflix give them enough detail to get some credit card info - even if it's just the last 4 digits - which is enough to call Apple and get your iCloud password reset. Once they iCloud password is reset, they can remote wipe your i-devices. That's not a hyperbole, either - that one actually happened. Their real goal was to steal his twitter feed - he was a journalist for Wired with a pretty good twitter following - and put up some very racist posts in a very public place. They wiped his computer and phone to make sure he wouldn't catch on until it was too late to do anything about it. [Details here](_URL_0_). \n\nMaybe they dig up news articles about you, or find past criminal records, or... who knows. Anyway, point is - we give out *WAAAAAAYYYYY* more data than we realize, and it absolutely can be used to hurt us. " ] }

why does my cat randomly turn vicious, even while purring?

{ "a_id": [ "c7xnjfd", "c7xnl4x", "c7xociy", "c7xs7ew" ], "score": [ 4, 21, 3, 3 ], "text": [ "Cats can be overstimulated by petting. Some cats are more sensitive to this than others. \n\n_URL_0_", "The truth is that no one *really* understands *why* cats purr. Cats mostly purr when they're happy, but sometimes when they're sad or angry or in a lot of pain, they purr then too, and we don't really understand why. Mommy cats who are having kittens sometimes purr when they are having the kittens, which presumably hurts a reasonable amount. So just because your cat is purring, it doesn't always mean it's because its happy and then suddenly angry at you.\n\nWe also have to remember that cats act differently with each other than they do with people, but sometimes cat behavior comes into their interactions with people too. When cats get together in \"feral\" (that means they have no owners) groups, sometimes they communicate with each other by licking each other. When they're licking, sometimes they bite each other to get knots in each other's hair out, and it's considered kind of a \"love nip\" - they do it because they're being friendly, not because they're mad at you, although biting you to tell you he loves you does seem kind of silly. We also have to realize that kitties play with each other by play fighting, and that often includes scratches and bites - your kitty may simply be trying to play with you! Also, as Mrs_Cake says, sometimes you can pet your kitty too much and they get tired of it. Sometimes they just want to sit quietly in your lap without being patted or rubbed.\n\nUltimately, cats are small versions of vicious hunters we keep as pets in our homes, and sometimes we can't fully explain animal behavior. If your cat is purring in your lap when you're petting it and suddenly scratches you, he could have a lot of different reasons for doing so. Play biting is normal and can be a sign of affection. Serious scratches might mean that kitty didn't like the way you were petting him and has no other way to tell you so other than scratching you and running away. Light scratches might mean that kitty thinks you're trying to play with him.\n\nBut if kitty always comes back at the end of the day, you can rest assured he still loves you. ", "You could also potentially be hitting a sensitive or sore area of the cat while petting them. \n\nFor example, my two cats are both fixed, and if you rub their stomach area (even 6 years later) the wrong way, they will nip in warning. If you keep pushing, they'll scratch and run away. But they love having their stomach rubbed, just in the right way.\n\nPay close attention to a cat while touching them. If their tail starts flickering over the place or they're squirming, those are warning signs. It's very easy to pick up on them once you know what you're looking for, but a lot of the time these signs are misinterpreted. \n\nThis could also happen as the cat ages and gets arthritis or if the cat has ever had an injury. Watch for the triggers and if you see it's a consistent area, have that area checked by a vet.\n\nTypically sensitive areas in my experience are the stomach and tail, and sometimes the top of their head.", "What are you doing when the cat turns vicious? Where is the cat?" ] }

why and how do people develop commitment issues?
explainlikeimfive
https://www.reddit.com/r/explainlikeimfive/comments/6b519m/eli5_why_and_how_do_people_develop_commitment/
{ "a_id": [ "dhjt6ir" ], "score": [ 5 ], "text": [ "There are several fundamental development stages, from in utero (while still in the womb!) to late infancy and early childhood that are critical for attachment style development. If any one of those stages is interrupted, or the mother or primary caregiver is inadequate in their response to the infant, this will lead to dependency issues (commitment or over commitment, we would call it \"being clingy\") later on in life, compounded by any failure of later development stages. For example, an under-responsive mother or primary caregiver at birth, during the mirroring stage, will lead the child to have abandonment issues. Put more in 5 year old terms: If mom doesn't come when you cry, doesn't give you loving attention, ignores you, that can \"mess a kid up\". Overbearing or overly responsive primary caregivers can cause retreat as well, but the behavior of the child can be intercepted or interrupted at many stages. For example, if during the separation stage of development, the primary caregiver doesn't let the child individuate, or push themselves to be independent (\"No! I do it!\"), they can develop commitment issues, feel suffocated.\n\nAlthough commitment issues can, of course, develop from adult faulty relationships, or appear to, it can theoretically be traced back to that.\n\nThe attachment style we generally attribute to someone having \"commitment issues\" is called \"Avoidant\" in attachment theory. Relationships will feel suffocating to them if, for instance, the primary caregiver was more interested in getting attention FROM the child than giving it TO the child. There's a lot of variables, OP, but basically commitment issues come from 1) poor infancy and childhood development stages involving connection and independence and/or 2) adult traumatic relationship experience.\n\nNot a professional just know a lot about this." ] }
