Calculus gets a bad rap for being difficult, but if you're learning on your own, you can just focus on the ideas and not on the arduous computation (which something like maxima can do for you). The core ideas of calculus can probably be learned in a week. Review all the trig on Khan Academy, then try watching some calculus lectures, focusing on the big ideas, not memorizing rules for computing derivatives or integrals.

BTW, you probably don't need much calculus to learn most of the linear algebra you need; those requirements are mostly there for mathematical maturity, plus then being able to assign more interesting exercises.

Public transportation sucks at a fundamental level. It's a graph with an extremely limited number of nodes on a completely fixed schedule. That's clearly inferior to free travel from any point to any point.

Given equal travel time I'd pick an autonomous car over train or bus 100% of the time. I'd pick a self driven car 100% of the time when not inebriated. For the most part faster travel time in a train or bus isn't a sign of their superiority but a sign of failure in proper infrastructure for cars. =I've been throughout Europe. Including two weeks in Vienna. I still think public transportation sucks and asking for more is asking for a faster horse.

In the United States I'd argue there isn't a single city with good public transportation. Not one. Some folks will list NYC as a good example. I don't consider a city with the single worst commute time in the entire country as a positive example. [1]

Now if only I would remember to wear my Fitbit.

I keep forgetting I've put it to charge and never put it on.
I will give this a thought and see how I can plan my upcoming weeks. I have considered about canceling my every-day growth hacks to focus more on larger "hacks", and also finding users and helping them getting started. Let's see what happens :)

Thank you for your advice!
I think multi-threaded (and thus off main thread) image decoding landed on Aurora 22, and I assume made it into that release.
Studying at a university where all this and more is part of the first year education of computer scientists, I - probably foolishly - assumed basic linear algebra was common knowledge in the community. Now my interest is piqued: Which educational path / career path did you take ending up in IT and (more specifically) how much mathematical education did it include?

What is your educational background and which route
Nowhere Man (TV) was more scary, by far.

http://www.imdb.com/title/tt0112104/

Sure, X-Files had boogie men, big baddies, conspiracies. In Nowhere Man the evil was ubiquitous, bureaucratic, banal, and terrifying.
Definitely not photoshopped. I see these deer everyday. In fact, there are quite a few more now.
I live close enough to my workplace and the basic necessities that I could walk to them if I so choose. Most people who own cars now live so far away from these things that they can no longer live without their four-wheeler. That doesn't seem all that free to me.
I know what you mean. Many of the hacks' results may collide. I wonder what a possible solution to that problem could be?
Based on this paper, I'm not sure I'd want to rely on something like BLE for payments: http://0b4af6cdc2f0c5998459-c0245c5c937c5dedcca3f1764ecc9b2f...
In that hypothetical scenario, the police would be responding to an attack (staged or otherwise). Later, the immediate security measures put in place in response to the attack simply wouldn't be wound down over time, maybe because of additional attacks against notable weak points of the existing security measures. Also, cell phone and Internet service would be shut down (ostensibly to prevent attackers from triggering remote detonators, which obviously could never have timers or dead man's switches), thus preventing the on-duty emergency security police from getting news from an outside source.

It's an interesting hypothetical scenario which exploits the good intentions of the police and military to do evil.
Sure but you're calculating the ideal case for you and worst-case for the truck. Not everyone buys a gigantic 4x4 crew cab pickup. There are plenty of regular bed length, single cab RWD pickups on the road and they don't cost $60k to buy.

The Ford F150 base model goes for $25k or so.

http://www.ford.com/trucks/f150/pricing/

A base model Yaris goes for $14k.

http://www.toyota.com/yaris/#!/Welcome

And that's presuming you're buying new! There are a great many used pickups for sale and the parts tend to change less frequently because pickup design parameters change much more slowly than car design parameters do. Because the design changes more slowly parts tend to be around longer and cheaper. And because the design of a pickup is driven by the need to have a 4x6-8ft long bed they tend to have roomy engine compartments in order to keep the proportions "correct"

By your own admission if you did at least one project per month requiring the use of a truck you would be spending the same amount of money. Perhaps that's money well spent to you, but you're not everyone.

There's no "right" answer here, only a spectrum of options that are better or worse depending on your personal preferences and the kinds of activities you undertake.
That or if someone invests heavily enough into building a coherent linux desktop.

There are a lot of great things about linux and some of the desktops are quite good (gnome 3.4+, kde) but they just aren't quite there with the small glitches and annoyances that come up just often enough to be off putting for end users.

I think linux or another free OS needs a huge backing to make it mainstream and we may see that with android (or something in a similar vein) in the future but for now the desktop is left Apple and Microsoft

I have a very close family member who went missing and eventually was found homeless. In the course of the investigation we found that several people exploited and took advantage of him for personal gain.

If you study the issue (like we did) you will find that this is a common and recurring problem, as homeless people are mentally vulnerable and open to narcissistic individuals.

Nothing against helping others -- I myself volunteered for social-change tech ngos for several years. My problem is in exploiting a vulnerable person for personal gain, which this guy is obviously doing.
If it is true that a large proportion of bitcoins belong to s a small number of people it has some pretty extreme consequences. It puts the effective monetary policy of bitcoin in the hands of random individuals. If they want the value to go down they can sell more, if they want it to go up they can sell less. Controlling that amount of the market makes them a defacto mint. That is a worrying scenario. It also is a complete opposite of the decentralization that bitcoin is supposed to represent.
You Can't Talk Housing Costs Without Talking About Zoning
I now blog at http://ta.gd/mypost no ads no nothing, it really just a feed for all things tech, also original post. About 3 years ago I had a news blog called alternative news daily which I sold for about 7 times revenue. My best day ever I took down 800 and change in a day.

It was during the bp oil spill ordeal, I heard Lindsey Williams on a talk radio show talking about all the toxic chemicals and gas the spill would produce, and how the worker were getting sick from it.

up until then I had never heard of anything like this in main stream news, so I wrote a lengthy article on it. A few days later guess what... The story was a hot item in main stream news! Not only did alternativenewsdaily.com have the top position in search, the distribution channels I submitted the story too made up the rest of the serps. Traffic poured in by the thousands and my ads were catching clicks like crazy. Later on the momentum wore off and I was drowned out by NYTimes, huffpost, and others, but that short time I was on top was freaking awesome.

I still have decent ranking blogs that I will try to post breaking news on as soon as I hear about it to try to get a jump on mainstream outlets, I monitor drudgereport for that, but I doubt I'll ever get anywhere close to that day traffic surge.

I believe that the number of politicians being extorted by various secret services based on such information to act/vote in a particular way (in the US and abroad) to be much higher. In particular, many politicians in the EU seem to be aligned with US policies (those unpopular in the EU) a bit too much. They've probably got a lot to hide..
that's true. i'm assuming when you actually ask someone: "100 bucks or coding lessons" the guy is going to be curious and ask a lot of questions.

Thank you! Almost forgot that we shouldn't spend time teaching willing people in rough situations useful things because it's narcissistic and patronizing.

I appreciate your reminder that the correct approach is to keep a safe distance and loudly bemoan the problem as "a complex issue".
You can package the Phonegap App with Phonegap Build, a service running in the cloud for exactly this plattform-problem.
You raise very good points, and I think about those kinds of things often.

Do I think hunting is the ultimate answer? No.

Will I hunt for the rest of my life? No.

Right now, I'm learning a lot and my awareness and perspective continues to grow and change almost daily. When I stop learning, I'll likely stop hunting.
OK, but to be fair, this seems to be slimy behavior on the part of Elsevier, not Academia.edu. Why should academics give up self-publishing rights just to go through peer review and get published?
Not difficult on an absolute scale, but definitely more difficult than getting your keys, going out into the driveway and driving off.

So it depends on how frequently you use a truck as an input into the cost of owning vs cost of renting equation. At once per year it absolutely makes sense to rent. At once per day it absolutely makes sense to own. Many use cases fall in between.
Is there another way to easily send him 70¢ while supporting his work and making him feel it has value other then buying that app that I'm unaware of? I'm not sure how much action constitutes "real" to you however pressing the buy button seemed to be a real action in my book.

And the 30% to Apple/Google is their share of building an ecosystem where a homeless guy with a laptop and some knowledge can produce a sellable product to help improve his life. They worked for that 30%.

It's not just that. Most of what makes Doom a good game has to do with the levels design, the secrets, the good balance of weapons vs enemies, and so on. Doom is still a very good game to play nowadays, much more than the boring and horrible Doom 3 for example (or even Rage for that matter).

You can convince yourself of the importance of level design by comparing the Doom mods vs the original game. Same mechanics, but the level design isn't as good and it changes everything.
I would say laws( the ones we usually define in physics ) are consequence of physics and don't really exist.
Such things were popular more than 15 years ago, when websites had to conserve bandwidth (for many users with slow links) and JavaScript wasn't considered as dangerous as it is now (so people didn't use NoScript much and didn't frown upon JS-only websites like I do).
Looking for Real Problems/Examples to Help Learn JS
I'm trying to help a friend learn js. He's working on codeacademy and also on khan academy but he feels like he's being rushed.

What hes looking for is some problems(/koans?) to help him really develop each concept he's learning-- whether its variables, arrays, etc.

There HAS to be a list of problems out there somewhere to help develop ones skills within each area of study. Have any of you come across one/made one?

Any recommendations? Thx
It is a serious issue, but I don't think the guy's goal was to reduce it to a game, but to do something well-intentioned.

In a lot of ways, what he's doing, on a small scale, is similar to the street newspaper concept that has gained significant popularity in cities worldwide. (Disclosure: I do some volunteer layout for such a newspaper.) The guy has a way to build income for himself now, and has learned skills which could someday be useful. But most importantly, he didn't have a creative idea foisted onto him. He came up with it on his own. It might not make him a ton of money, but there is the potential it'll make him a few dollars he didn't have before.

That part about coming up with the idea on his own is huge—way huger than you think. That is something that will help Leo build confidence in his own talents. It's exactly why street newspapers are largely written by the homeless, rather than merely sold by them.

I'm not saying that this is going to solve anything, and as we've learned from similar stories (golden-voiced Ted Williams, made-over veteran James Wolf), these situations often turn dark and raise huge ethical questions the second the person relapses in any way. So maybe it's not good that our energy is focused on two guys, one of whom may find himself unprepared for the pressures of unexpected fame.

But I think that there's something to be said about the fact that McConlogue is thinking about how to scale the concept. If he turns this idea into a nonprofit driven by donations, who knows what could happen next?

I don't think anyone expects what happened here to solve the problem. But there's some room to expand and build this idea. What if, like street newspapers, this concept grows into a way to build apps for the homeless, apps that work on easily-obtainable prepaid phones that help the homeless obtain easy access to public resources often hidden away by paperwork or location, or apps that make it easier to receive assistance from a bystander? Maybe you could even create a task-based micropayment app that allows people in such situations to raise money for themselves by performing small tasks like taking photos or reporting on their surroundings—say, a Mechanical Turk for mobile. Perhaps it could use a gameplay style similar to Waze or Foursquare? I'm spitballing here, but you see what I'm shooting for.

Maybe it's wrong that we're focusing our energy on a single tree when there's clearly a forest that needs to be dealt with first. But you know what? I'd rather that someone at least try to plant a seed rather than immediately dismiss the idea out of hand.

I don't see where the OS's RNG functions are being deprived of such entropy as the hardware RNG provides; it looks more like the hw RNG is being used as one of many inputs to the OS RNG instead of as a completely trusted substitute for the OS RNG.
How to Get Mark Cuban's Money
we found that several people exploited and took advantage of him for personal gain.

which this guy is obviously doing.

You're not projecting your own personal experience into this story at all, are you? The only way for you to draw this conclusion is to have spoken directly with Patrick McConlogue, and for him to confirm to you that his motives were to exploit this guy.

Two people can have wildly different internal motives that produce similar-looking behaviors. Careful with your snap judgments.
The other aspect is that they actually want to discourage them from carrying so much stuff. They have many problems with back pain and the such. And like the other guy said, they want Missionaries "to look professional, and backpacks are not professional".
Thank you for that description, now I understand it at least on a basic conceptual level.

Humans can certainly replicate TMs. It's uncertain whether a TM can replicate a human. If the Universe is a simulation running on a TM, then humans are replicable and therefore Hard AI is possible on a Von Neumann architecture, which would be an exciting discovery.

Patent applications filed before the end of 2000 were not published. You can in effect file a continuation as many times as you like, and rewrite the patent substantially as you do. This leads to a tactic called submarine-ing, where you keep filing continuations on a patent that is repeatedly rejected for being overly broad. Then once a concrete target appears on the horizon, you narrow the patent to cover it before prior art, etc is well established.

It's no longer possible to do this with patent applications filed after the end of 2000 due to reform. The period the patent is in force no longer shifts forward with the continuations. But previous applications were grandfathered in.

Hi, EFF employee who worked on our acceptance of Bitcoin here.

The linked article simplifies the history somewhat. In fact, we attempted to give away all of our BTC to the Bitcoin Faucet because of legal uncertainty surrounding Bitcoin.

When we decided to start accepting Bitcoin donations again, the developer who runs the Faucet offered to return the remaining value to us. Because of increases in the price of bitcoins in the interim, EFF was able to sell the BTC that came back to us from the Faucet for about $95,000.

https://www.eff.org/deeplinks/2013/05/thank-you-bitcoin-comm...

By my calculations (using contemporary market depth data), that's coincidentally just about the same amount of U.S. currency that EFF would have realized if we'd sold all of those bitcoins at the time that we donated them to the Faucet. I'm glad that that value was eventually able to be used for EFF's purposes as the donors originally intended.

Since deciding to accept Bitcoin again, EFF has used a payment processor to sell all bitcoins as soon as they're donated, so we never possess them and never make individual decisions about when to sell or hold them. (That's what will happen if you donate in BTC today.)
"But it seems like not the useful insight given a state the clearly has asymetrically greater power than the populace?"

Is your assumption true? That is, leaving aside the fact that the police are ostensibly part of the populace, how would some police and a single APC pacify even a couple of blocks of citizens without the cooperation of those citizens?

Personally, and I realize that this is opinion, I do not believe your assumption is true, and as such is a pretty good example of why the ideas you are critiquing are useful- it is difficult to see the larger system of power described by the ability or inability to motivate people.
Because, before the internet was widespread and used for distribution, the only way to get your research out was to be published in journals. Part of this deal involves handing over the rights to your paper to the publishers. This is pretty standard procedure: JK Rowling isn't going to be going giving rights to penguin books for the Harry potter books while she has a contract whereby Bloomberg publish the books currently, it's a similar idea.
Additionaly, the measure of an academics success is based on his (or her) citations, and if your citations are from "website of some guy", nobody is going to take you seriously. It's a vicious circle, and the whole system needs reforming, however the thing is, conferences such as SIGGRAPH, FOCS, INFOCOM etc etc all play an important role, that they offer peer reviewing, and you can guarantee quality (if something is published in SIGGRAPH, then you can normally rely on it). Until there are viable alternatives, which are accepted and can ensure that the quality of the articles appearing is of a high enough quality, this isn't going to change.
Uruguay legalises production and sale of cannabis
From your perspective, what should McConlogue do or have done differently? He's obviously going to benefit from the exposure but I don't see any evidence that he's throwing Leo under the bus in the process.

It seems like a mutual gain to me, compared to a do-nothing approach. If the news story were "Leo goes back to square one after software engineer ditches him after getting publicity" then it would be a different story, but for now, the cynicism feels pregnant but premature.
This actually makes a lot of sense to me (someone from an urban area). I never understood why all these towns in the middle of nowhere USA would offer such generous subsidies but this line of reasoning perfectly justifies it. I suspect the cost to decommission or "right-size" these sorts of facilities would probably cost... on the order of hundreds of millions of dollars.
