Well, it's the opposite perception here.

"I've rarely seen - and its possible that this is selection bias - companies start with the other NoSQL options."

It seems like everyone starts with Mongo, because everyone starts with Mongo.

This means that you don't have the deluge of posts from people moving from other databases,

a) there are much fewer of them
b) they chose them for solid technical reasons (not just because everyone does this)

So as for your perception that other NOSQL databases are "probably" more complicated, you should know that complexity is an objective measure. I think that mongo is definitely a lot more objectively complex than couchdb, and from what I have read around the subject, many of the other NoSQL databases.

What Mongo could well be is 'easier', which is relative. It seems like it's more familiar to certain programmers, which is kind of echoed by the fact that there's an incredibly popular object relational mapper (mongoose), that is being used with what is supposedly a non-relational database.

I use those terms in a very specific sense btw, which I documented here - http://daemon.co.za/2014/03/simple-and-easy-vocabulary-to-de...

Tips for a young dreamer and developer [Help]
Hello, I've just turned 18 years old and since my 08 years I program (Visual Basic, Python, C, C + +, Ruby, D, Javascript and others) and in these 10 years I have learned a lot!

Currently I am dedicated to making startups and projects, and I have great interest in furthering me in math (currently reading "Discrete Mathematics with Applications") and artificial intelligence.

My big problem is:

- What language study the background to artificial intelligence? (Clojure, Lisp, Haskell, Scala, Python?)

- Which books to be read based on artificial intelligence and then continue in other subdivisions?

Thanks to everyone, and unfortunately I did not know whom to seek to take these doubts. Today I live in Brazil, and is very difficult to find people who can help me with this, most young people are in parties or playing games ):
Siphoned out of what? No one is making you give HFTs money or buy from them.
Sorry, my mistake. I guess I just assume everything is a webapp these days.
So should we get rid of trading pits as well? Thats another form of colocation.
And why wouldn't this work today? Imagine getting an awesome piece of kit like your PS3/4 and being able to code on it, run anyone's code on it. Hack it to your heart's content. I reckon that would (a) rock. (b) foster an amazing community. The things that made the Amiga rock could make any specialist piece of hardware rock, what's prevents it is that companies like Sony and Microsoft are anal control freaks.
That was an oversimplification done for the audience's benefit. If the video were a math class, he would have said "without loss of generality, assume that the market is going up."
"Real estate is cheap[er]."
Trouble? It's a single REST request to get a couch database continued indexed in elasticsearch in almost 'real-time'.

It just subscribes to the _changes feed and updates the index, in the same way couch replication works.
It is not uncommon for manufacturers of 'systems' to hedge their bets by becoming suppliers of components to competitors. Examples abound in the cell phone industry: Samsung makes Apple's A series chips and possibly, other components.

It is not a certainty that Tesla's battery manufacturing facilities can lower the price of batteries to achieve the < $30k per-car price point. I'd imagine a single factory that also sells to other car makers will solve the existing problem with scale. Currently, making/procuring 10k batteries a year is probably a big factor in making them so costly. It is almost universally true that manufacturing in larger numbers will bring down the price (probably not in a linear way, rather logarithmically).
We usually just add "[video]" when a video autoplays, even when there's an accompanying text article as well.

Do I detect an annoyance with autoplaying videos with accompanying audio in your suggestion? If so, I share it.
> It would be a problem if someone else could create a droplet and recover your data, not when you can do it.

This. Sometimes it really is better if it's not truly gone forever - in other words, you still have the option of recovery. I'm speaking from the experience of someone who has accidentally lost important, irreplaceable data that had yet to be backed up.

Especially after reading this:

There was also an incident where a third party provisioning service which integrates with our cloud as well as others was compromised and all of the servers for those customers were destroyed
I'm not sure I criticize a service for not destroying my data by default when there is an easy way that I actually can destroy my data.
It doesn't since most HFTs (and many other systemic traders) are valuation neutral and trade in both directions.

Did you watch the news clip? And the Department of Energy (not mentioned) was huge in getting Tesla to where it is today.
GPL3 certainly does.

Linux itself is fine with the GPL. Thats an OS only.

The problem is usually the Linux dist. Their solution to the packages problem is to include the kitchen sink.

Licensing is along the lines of "what's that". Ergo you use FreeBSD (or one of the others) when you need to have something to satisfy lawyers.

It's all tracked.

Companies can modify some minor bit for their "secret sauce" and bundle it up inside the vacuum cleaner. Not the hacker version.

Since the internet of the future is the "internet of things" that's kinda important.

Why? A patent lacks full disclosure if it doesn't have enough information for a person skilled in the art to reproduce the invention; it must be enabling. Patents are not about specific implementations of an idea, they are about the idea itself. IMO, patents are much more accessable when they are written in plain language than in a specific source language because the ideas may be understood at the higher level that the patent protects and allows for implementation in any language.

Do you think that pharma companies should have to provide working versions of their drugs along with their applications? They usually do not have a fully working implementation at the time of application, and won't have anything they can prove works for many years after the necessary regulatory testing is finished. The same for huge mining equipment, it might take years to actually manufacture something that works, but the invention exists once it has been invented, not produced. Why should software be any different? We've grown used to a world where many people freely share their software, but that is their choice, not a moral obligation, just like any field of science.

Lastly, one thing that really irks me about the software patents debate is the constant dissing of patents because the idea is obvious. Of course it's obvious once you know the solution, but that's ex post facto analysis. Invention comes from discovering the solution, not from the complexity of the solution itself. I personally feel that things like the slide to unlock patent are more deserving of an innovation patent than a full patent, so there are definitely cases where things have gone wrong. But I do not believe the majority of cases fall into this category.
Literally how do you compare the debatable liquidity value to the debatable cost to those who didn't pay the toll? Why are those who didn't pay the toll more deserving and necessarily more benefitting to the economy? If there is increased liquidity aren't the non-HFTs starting at a lower price than they would've, even if part of their order is more expensive? I'm asking honestly, I don't know either way.
I think the moral of the story is that if you are so concerned about IMMEDIATELY deleting your data and a 48 hour period where you can recover it is unacceptable, you should definitely run your own servers.

I did read the theory of OS by Silberschatz, Galvin et. al. I needed something that had more real-world orientation with source code references.

I think the most interesting thing about Tesla is it's applicability to SpaceX. If the goal of Tesla is to provide a better energy source (where "better" is defined as capacity and environmentally friendly) and SpaceX's primary constraint is the energy source, then long-term they'll be the same company.

You're right of course that the reason money has low transaction cost is because it is widely accepted. But that's kind of tautological; if it wasn't widely accepted it wouldn't be money by definition.

In my mind the low transaction cost is a feature in that you can make snap decisions (or in many cases not make them at all) without having to explain yourself.

What I mean is that if I had to itemize every gallon of water, every kilowatt-hour (or watt-hour) of electricity, every cubic foot of natural gas, every byte I upload or download, etc etc etc to come up with their "true" values I wouldn't have enough hours in the day to do 10% of what I normally do.

So I guess my question is this: at what level of granularity is this being proposed? And if it's anything less than "full granularity" why? What I mean is why should utilities be any less valued than phone apps? I need that first gallon of water WAY more than I need Angry Birds, so it seems to me like that needs to be accounted for. But that would be exhausting. I can't see a way for me to take this proposal really seriously AND not simultaneously want to hang myself.

I think it's an interesting idea to be sure, and it's fun to think about. But I really hope I don't have to tell everyone how much I like water or electricity or whatever.
sound advice but may not fit if the OP was being driven by something other than making money. Also, some people have been doing the side project route for long enough to feel it is not working and they need to devote more time.

i applaud the OP for pushing themselves but also agree that a well paying job is an option they may consider. Better yet, just variate between them. Spend a couple years trying to find collaborators and push projects, then a couple moving slow and steady on the side.

We already have "equity crowd funding." It's called an IPO.
Mock wars: Yes! We did the same, to the point where we had diplomats and assasins, and it spread across through class-time as well. It even started my entrepreneruial spirit: I packaged up and sold "ammo" (rubber bands set up for maximum power and a small "gun" to shoot them from, tagged with a colour for your team) haha. Of course, that was very much a no-no (you'll get hit in the eye and go blind!) but it was amazingly fun and I'm pretty sure helped us understand tactics far better by applying them in the real world ;)
I hope it is close to zero. Proprietary bullshit is bullshit.
Tesla has always said their goal is to accelerate the adoption of electric vehicles. I suspect they will try to sell other car companies the drivetrains and rights to the super chargers.

While Buddhists are undoubtedly correct that suffering is caused by reality not meeting our expectations, their solution is problematic. Many times our expectations re-shape reality so that they are met and we are happy. If we stop having expectations and accept reality just as it is we miss out on all those opportunities.
I don't understand hacker news' dislike of politics... do most programmers not find it exciting?
The charging network also has a lot of risks associated with it. There are 192 other countries in this world all of whom will be looking to charging standards as opposed to relying on a single American company. This means that some time in the near future Tesla will have to go back and retrofit their cars/stations to meet this standard.

Apple's walled garden strategy works because the devices are cheap and relatively throw away. Cars are not.
Yeah, look I agree with the general sentiment of letting kids take risk and learn responsibility, but my two small kids (who do skateboarding, BMX racing, surfing, rugby and a lot of general "rumbling") are NOT allowed to ride without helmets and I wear one too. I survived not having one as a kid (nobody did then), but I wear one too now, and seriously the upside/downside equation here is a no-brainer.

Other than that - let 'em at it!

I think a big issue is that Oakland is way bigger than people think, especially geographically - it covers more land than SF - and there's a lot of diversity. Some regions are really bad. Some regions are ritzy. There's plenty of everything between. But the news doesn't differentiate well between the different parts of Oakland, so when you hear over and over that there was crime in Oakland and you're sufficiently unfamiliar with it that your model has it as an undifferentiated blob, and you think that blob is smaller than it is, of course you think anything about Oakland is scary.
Not to nitpick, but the phrase "intellectual property" was nowhere in use before the 1940s. Modern use of the term is highly tendentious.

No, they're not. You may like to believe this, but it's not a fact. Many inventions are quite mundane, but doesn't mean they weren't inventive (ie, non-obvious) at the time. And the other thing that most people seem to forget is that examiners must be able to show that the invention is obvious to be able to object to it, there must be proof that a person skilled in the art _world_ do X. you might counter that by saying the applicant must say why it is inventive, but that's something that is impossible to do (except in circumstances where the common general knowledge in the art has been that X is impossible, and then you show that you have done X).

Simple things should not be ineligble for patents, and what you are proposing is excluding from patent protection anything that is simple. Also if you're looking at a patent that is in a field that you're skilled in and you can't understand it "ok, it's right in front of my eyes, but what is this magic?" then the patent hasn't fully disclosed the invention and it shouldn't have been granted (or you're just not skilled enough, many patents require vast amounts of knowledge to be able to understand and the "person skilled in the art" may be a team of people).

If it's obvious in hindsight, it's still obvious.

The trade is: we give you a monopoly on the thing, you give us (the public) written step-by-step instructions on how to create that thing.

If instructions aren't necessary to create it — i.e. I can figure it out from just seeing it — then the deal is broken, and isn't serving public good any more.

They're getting their monopoly, what did we get? Zilch.

This is the problem with patent protection in our industry. We can recreate things pretty easily. In say, biotech, it's much harder to figure out.

I'm still behind just scrapping patents altogether though. It's adding process for process' sake. The same feeling you get when you have big section of unnecessary code, and ripping it out has a no effect on the result — patents feel like that chunk of code, before you rip it out. They seem like another area where people have created work for themselves effectively doing or creating nothing. If we got rid of them, not a lot would change, but millions of people would instantly have less weight on their brain.
The IRS now treats bitcoin as a property asset, very much the same way they treat stocks, and not all stocks are prone to speculation. So this is expected news for those who hold bitcoin as an investment.

The major impact of this decision will be on consumer adoption. Now, every time I want to make a transaction, I need to keep track of my taxes. I know that some wallet services are already developing ways to keep track of this automatically, but that's just an extra headache for the average consumer. This in essence will force consumers to think of bitcoin more as an investment, rather than a "currency" they can spend, and that will impede adoption.

I know nobody here likes to hear it, and I feel like a lot here in SV are tuning this out, but bitcoin is really, really struggling to find a relevant use case with consumers. Regular consumers have absolutely no reason to use bitcoin. The "1-click" payment and 1% price discount are not appealing enough to the average Joe who already gets 1-2% cash back, airline miles, and consumer protection on his credit card (and 1-click checkouts on many e-commerce platforms). And more regulation isn't helping the "crypto-anarchist" decentralization angle either. Add price volatility to that and it kills the consumer use case.

But... micro-payments? Consumers have always hated them. http://www.openp2p.com/pub/a/p2p/2000/12/19/micropayments.ht... (Shirky, 2000)

But... international transactions? Hard to beat the fees at https://transferwise.com.

Bitcoin is great, FOR MERCHANTS. But consumer adoption is going to determine whether or not it succeeds on a grander scale. Unfortunately, Bitcoin does not solve a problem for consumers. Especially with tap-tap mobile payments around the corner.

When it comes to money, consumers want to be insured and cuddled and protected and not run the risk (however small) of being criminally liable for transactions and have someone to speak with if they make an erroneous transaction or have their card stolen. And they can already do all that, which makes it tremendously difficult to compel them to change the habits they've had for in forever to adopt a system that does not provide them with significant advantages.

I've been in bitcoin since 2011 and used to be a big believer, but I don't see bitcoin gaining traction with consumers, in part because of the huge regulatory risk. Any significant threat to the banks' business will be met with harmful regulatory control (friendly reminder: Wall Street banks fund the largest political lobbies in Washington). It could be destined to eternally remain an investment instrument (like gold) or find very targeted applications (like machine-to-machine payments). The underlying blockchain technology could be of more use (if adopted by the banking system, for example) but that is still far in the future.
I don't disagree that encapsulation has a place, but it's not the universal right answer. Sometimes it makes sense to use inheritance, and sometimes it makes sense to use encapsulation.

The article was arguing that inheritance is wrong, and using a (broken) biological metaphor to back up that argument. In fact, it's pretty easy to argue that the coding example was broken in the same way -- you could resolve the stated dilemma (using a transaction history instead of a current balance) by creating a new subclass at some level of the original hierarchy. And if you can't do that, you possibly had a broken design from the start, or you really did need to re-work all of your original code to adopt to the new implementation (or both).

Mixins don't make your code magically adaptable to re-implementation. They force you to encapsulate more stuff, but you could just as easily design an inheritance hierarchy with the same properties (i.e. make subclasses all work with private data via protected methods), or you could adopt a hybrid approach -- for example, one could imagine making the class hierarchy in this post using a Strategy pattern to implement the actual tracking of balances.

Usually, when people have an axe to grind with inheritance (or encapsulation), it's because they've run into the problem that code design is subjective and imperfect. Programmers don't like that much, and it's more fun to blame the tools.
2 thoughts:

1) Try being more specific - http://lesswrong.com/lw/bc3/sotw_be_specific/. Perhaps you've been failing because you've been building things people don't really want? If so, being more specific will help.

2) Perhaps it isn't worth "slaving away" on startups. I believe that the 80/20 rule is very powerful, and is applicable to startups: a small amount of the work leads to a majority of the success. Maybe you could live a less stressful life, and still work on startups.
