Yes, I did. An open hardware building system called the hexayurt.

I started in 2002, and went through years of working with shelter charities, the US military and various other groups to get the technology into the field. There are experimental units in Haiti and Sri Lanka right now!

On the way I learned a hell of a lot about how the entire mess works, and why humanitarian innovation is so slow. There's a couple of talks on the hexayurt web site which might give you useful context: "Ending Poverty with Open Hardware" and "Enabling Humanitarian Innovation."

Please feel free to drop me a line if you have specific questions, and do check out Google Image Search on hexayurts to get an idea of where they're being used most right now!

We'd love to have anyone passionate about changing the world of education apply to Khan Academy.

I understand your point.

However, it might be that as cloud services become a critical for businesses and individuals will not be going for "free" solutions. Reminds of "Starbucks dilema": wanna a cup of coffee for 50c and have diarrhea or Starbucks coffee for $4? And how hard could be to make a good coffee?
It seems to me that the cons far outweigh the pros here, cons being: increased costs, trapezoidal issues when throwing to a wall (requires machine vision to map wall and adjust dynamically), durability issues, input issues (impede image to adjust OR interact with device, which will shake the image), lighting requirements. Plus, exactly how often does the situation arise where something needs to be shown and there isn't a suitable screen around? We have laptops, iPads, and often the smartphone's screen suffices.

Apple are wizards though, and if they can do the impossible here then it will be a huge score for their hardware/software advantage.

I doubt you'll be able to do much better with another scalable storage system (that's freely available).
Those critical of BART's action will say that stifling communication for any reason is unacceptable and that even if most of the riders would have agreed, they weren't consulted. Some may also say that you can't let the sheeple vote on such matters because they'll vote wrong.
No -- but I will -- thx! I've tried nice, ionice, cpulimit and cstream.
This was much needed.
I've been using the iOS 5 betas and I can tell you I use Reading List and Instapaper completely differently. Instapaper has always been long form reading, stored for later (and potentially offline). Reading List, I use to quickly transfer a site I'm currently reading from my desktop to my iPad or iPhone, incidentally replacing an app I wrote to do exactly that. I guess it's time to take Panic's Audion advice and retire that app ("When you double click the competition in the morning, that's a pretty good sign that it's time to hang up your hat!", http://panic.com/extras/audionstory/)

Just to quickly follow up: the answer that the system accepts as correct is roughly the answer I get when I compute the answer to the question "if I pick an item at random from the list of 250 items, what is the probability that that item appears to be a special and actually is not a special"?

I say "roughly" because they're almost the same order of magnitude, but still off by a few insignificant digits.

I wonder whether that has something to do with either of these assumptions I made:

[3] No two items have the same code.

[4] Five DISTINCT randomly chosen items are "specials" (it is not possible for today's specials to be the first item on the list five times).
I agree with you completely. However, in a Democratic government the decision to limit the freedom of your citizens shouldn't be made based on how easy it is for you to do but whether or not it is the right thing to do.
This is great for motivation during a heads-down sprint.

What I'm looking for is slightly different: a place to show off when done and get/give feedback.
The word "epic" can be used to describe tone, not only length.
I'm the same type if I sleep in a bed - but a nap in a slightly uncomfortable position that keeps me from falling into a deep sleep does wonders. This results me in taking naps on the living room floor and feeling great and the girlfriend yelling at me about it, and taking naps in bed with her and waking up really tired and me yelling at her about it :P
Tubalr.com - On the fly youtube playlist, no registering required. Input wanted
I'm pleased to announce you can now create playlists on the fly without registering or logging into an account. It's simple, once you click the link to create a playlist on the homepage, just start searching tubalr and adding videos. Copy the URL and share it with your friends. Playlists are completely public for now, so anyone who gets the URL to your playlist can add songs as they please. In the future, I'll probably add a feature to have playlists with passwords, but for now I don't think it's that big of a problem.

I'm looking for some serious feedback. I tried to hit as many use cases as I could... but I'm sure I missed something and bugs are creeping around. I just wanted to get the feature out there in the wild.

Here is a quick playlist I threw together with some RHCP videos: http://tubalr.com/playlist/AVTOUMTT
I'm doing a project that I think will help globally albeit it's a hobby project (as long I finish it, haha). The thing about my project is that it's not about altruistic desire to help people, it's about building towards something grander for me, a home in space.

The YC and other entrepreneurs ALWAYS help people. If they didn't, their business folds. Because simply: it's not useful to people. eg They created an app to put moustaches on every picture; you may think it's not helping people but it'll give a smile to families who see the wedding pictures with moustaches everywhere. So, help to people is quite subjective.

On the other hand, it sounds like you're doing a 'numbers of helping many people for as little work possible'. This is incredibly hard. For example, if you give water to communities but you also have to deal with culture that creates inefficiency issues. eg Corruption, malice, war and population issues. Yes, you could be exacerbating the problem by making their lives easier but in long term worst as so many people are reliant on you giving water. Don't always assume that helping many people at once will be the best solution.

I hope you seek something that's very helpful and is long term solution for them. Even if it's only helping one person. If that person lives to wealthy world life expectancy, that's better than many suffering at once because that person can pass on knowledge, etc.

If you want to get some ideas, listening to problems is usually helpful, then brainstorm with it. eg over a million children are trafficked; maybe create cheap GPS transmitters for children so parents in home countries can track their children's 'work opportunities' and report discrepancies. Bonus: There's an awful lot of lazy people or people with not enough time that talk about ideas but never execute them. Since you want to execute something, you have a lot of research and brainstorm material done for you!

Last tip: Try to release your project! It's time wasted if you let it be in obscurity. If you don't want to do it any more, release it anyway. eg free code repositories, free blog post with project notes and research, etc. People like me who want to do something similar to you will be able to make use of it.
I can understand your confusion if you were expecting an article which discussed the fundamentals of RESTful interfaces and how it pertains to server client relationships. The intention of the article wasn't as much to introduce the concept of representational state transfer as much as it was, 'how can one use a RESTful API', hence the title, "Using RESTful APIs". I can appreciate that the introduction lacked adequate explanation of REST, itself -- and it's more than reasonable to expect an article on RESTful APIs to cover, well, RESTful APIs.

That said, I am thankful for your constructive criticisms and will revise my post so that its content is more satisfactory.

Pak, thank you for the w3 resource. As it says in the reference, it does seem that 256 was the limit for prior implementations; however, it seems my understanding was indeed based on outdated material. In response to your other criticism, which example is never shown so I may add it?

If you have suggestions on topics I should include or other resources I should review before making changes, suggestions would be appreciated.

Cheers

Does anyone know if Heroku has spread their services across HA zones?

I don't know for a fact, but the multiple Heroku sites of mine that went down concurrently with this problem would indicate 'no.'
I'm almost frustrated to see this. I just learned to use urllib2, and found that it took a great deal of effort to get any reasonable behavior. I wish I had known about this before. It really looks great and I will try to use it in any future work.
What was the thread you read? I don't think I recalled it.
From the title I thought this would be some kind of mechanical-Turk webserver.
The text is very difficult to read.
You know, I'll be the first to admit that Friedman doesn't hesitate to ignore any solid evidence and a look instead for the closest funny/shiny/trendy anecdote, story or buzzword. Gosh, even Malcolm Gladwell does better "research" than Friedman!

But presenting as counter-evidence a publication behind a pay wall is not much better, either.

Can you provide us more details than a simple hyper-link to an abstract that doesn't relate to your point?
Wow I was just about to start going through the pain of using urllib2 for the millionth time right before I read this.
"I'll show a second example which does pass data along with the URL" ... never happens.

Also, when replying to people directly, try to thread your reply onto theirs or that person might never see it.
I think people want a sense of purpose in their life, and being part of something grander than themselves. That's different than happiness. It's more like inner peace
I recall that fair use laws in some countries explicitly mention issue of using copyrighted content in news stories / for public information.

Unfortunately quick googling didn't find anything useful, and the wikipedia article is surprisingly worthless:

While many other countries recognize similar exceptions to copyright, only the United States and Israel fully recognize the concept of fair use.

Seriously?
Life existed before many things we now consider basic human rights. Safe food, safe vehicles (vehicles at all), etc.

So during the next protest they ban cars, including emergency vehicles? People got around just fine before cars.

I don't think you quite understand, we aren't talking about people not being able to all their friends, we're talking about 911.
That's curious. I initially tried a solution like this and got a result that differed from the expected result by a small amount. I discarded this solution and looked for others when rajatsuri said the first part of q2 assumes that the customer has already picked items that appear to be available.

Edit: By turning the 2 assumptions you mentioned on or off, I am only able to produce answers that are slightly too large or slightly too small. I wonder what the correct question is...
When you say "these sorts of issues", it sounds like you're talking about injustice everywhere. You want to fix injustices-- food for the hungry-- instead of "adding happiness"-- better food photos for people with smartphones.

In which case, I FEEL YOU. I'm infinitely more interested in SwipeGood than I am in Zynga. But everyone makes their own choices. Some people just aren't that concerned with injustice. Some people may have the same goals you do, and try a different path; nonprofits/NGOs always have good intentions, but not always good results (have you ever tried fundraising? it's not any easier than just making money.) And finally, it's a heck of a lot harder to fix injustices than add happiness. It's harder to scale, too. Much easier to build that photo sharing startup and be happy. :)

You should figure out what exactly you want to do. Injustice is too broad. Pick something and start there. You can try to pick something where you think you'll have "the greatest impact", but it's a) impossible to predict, and b) it's better long-term if it's something you're passionate about and won't burn out on.

Khan Academy, Kiva, DonorsChoose, and Samasource are nonprofits that are popular/well-known in the tech/startup world. Do any of those interest you? What about them interests you?

Where are you located? If you're in the Bay Area, there's a lot of people working in/on nonprofits/foundations, social enterprises, and other innovative social change efforts. But there are so many problems to solve; figure out what motivates you first. (There's also a lot of crap, just like in tech, and it's probably harder to tell the difference because everyone is just "trying to do good" and there are no easy success metrics like revenue or profitability.)

Good luck! I hope you find something that's meaningful for you and makes an impact on those less fortunate than you.
2005 Zuckerberg also lied point-blank when he claimed that nothing like The Facebook existed at Harvard (1:32 in the video). He knew about it, was a member and heavy user during the period in which he coded his version (http://www.thinkpress.com/authoritas/timeline.pdf). He repeated this false claim in his talk at Stanford's ETL lecture series and I find it absolutely infuriating.

It's also relevant that Mark appears so non-chalant about the whole endeavor in the video. That's more or less how he came off when I spoke to him a month before the site launched, except he was more coy, refusing to divulge what he was actually working on. It didn't sound like a business seeking venture capital financing whatever it was, and so I had no reason to think I should get involved. Nor did I suspect that he was actually willing to torpedo our relationship by copying my work feature for feature, seeking funding without mentioning it, and simultaneously asking for advice. Nor did I suspect anything about the fact that he was searching my Facebook for "winklevoss."

And yes, I've moved on, but each time these lies are uncovered fresh, no one else takes him to task for them.
A good friend of mine has a startup called SmallAct whose goal is to provide software that lets non-profits better engage with their donors through social media. It is a nice cross between the types of projects traditionally attacked by your typical silicon valley startup (they're based in DC however,) but instead of using that type of technology to support rampant consumerism or sharing cat pictures it's instead focused upon indirectly helping the global problems you mention.

> There aren't any colossal Go codebases yet, but so far things are looking promising.

Not really. Go keeps all the old errors everybody should know are errors (nullable pointers, shared mutable state, raw types, ...) and then proceeds to add new ones, and packages all of that in a less regular syntax just in case there was any chance to get a good language out of the previous clusterfuck.
The Ruby example actually involves generating the getter and setter at runtime via attr_accessor.

In contrast to Python, in Ruby all instance member variables are private.

Two tips:

• You can bend around obstacles in a number of ways, including parabolas, 1/x, and exponential equations, but one way I saw someone else using involved combining terms of this format: “a•((x-k)+abs(x-k))” (I’m using • because HN is swallowing asterisks). k is the x-value at which your equation curves, and a is the slope afterwards. Each term like this adds another point at which your equation can change direction. It works because abs() is math’s equivalent to the “if-else” – with enough convolutions, you can make equations conditional on almost anything. However, I think with this technique, you have to change parts of previous terms to account for the new term – I haven’t figured out how yet.

• Add k•sin(99•x) to your equation to give yourself a “beam” k high.

I'm tempted to write a program that can create an equation of piecewise line segments to fire. The inputs would be a list of x-values of the segment boundaries and angles for each segment. I probably won’t get around to it, but someone else, feel free to.

Awesome stuff. How many hours I've wasted futzing around with urllib2 and creating my own Request handlers and all that other nonsense. This lends itself nicely to working with 3rd party APIs (Facebook, Twitter) in particular.
I've been struggling with a similar question to the author lately. For me, what it boils down to is this: I have to spend 8 hours a day working on something. It seems like better value to be working on something beneficial to humanity than something meaningless, or even detrimental.

I would answer the question of "should you?" with a resounding yes.

I've been finding it difficult to match up my skills as a software engineer to a project with meaning as a lot of them are in the hardware or humanitarian aid realm.

Your point of doing "what's fun" or "what you like" is also an important factor and almost goes without saying. The ideal job for all of us is doing something we like that pays the bills and has a tangible benefit to humanity (not a made up one).
how does this compare with webob (http://docs.webob.org/en/latest/index.html)?
I think it's something like: (Total Points / Posts) / Days since registered.

Don't worry about karma anyway. There are some people who will downvote you even if you're completely right. Don't delete it if it's really contributing to the thread. Some people disagree with reality.
>stifling communication for any reason is unacceptable

Do you really mean that? Do you for example condemn the U.S. army convoys in Iraq for travelling with cell-phone jamming equipment after they learned that insurgents were using cell phones to detonate roadside bombs?
Smalltalk definitely belongs on the list, it's the only one that takes "object-oriented" to its logical conclusion (dispatch can replace control structures). I'd suggest omitting Elisp and ObjC—they're both lackluster imitations of better languages that will do far more for the way you think, unless you happen to be developing for their captive platform (Emacs and iOS, respectively).
I suggest you go read that FBI report. It warns of homebuyers and mortgage brokers committing fraud against loan issuers.

Clicking on the vid links doesnt work. I can enter a name - but cant click on anything (Chrome) -- EDIT: Nevermind - it was just delayed response. It works now...

I like the idea. You should promote it on Reddit. The idea of throwing together a quick ad-hoc playlist is a needed one - This just appears to need some work. (Get a designer)
Have been using this for a little while now. Totally awesome.

The simple example on the home page should have one more line of code that shows that you use r.content to get to the content that came back from the request. That would seem to be the most common use case.
I've been toying with the idea of an organization along the lines of Engineers without Borders ("Hackers without Borders"?) or something to that effect where developers lend their talents to causes all over the world. Not saying that an iPhone app can solve everything, but I'm sure there's quite a few ways where simple apps here or there could make a big difference.

Does anyone know of something like this out in the wild already? Seems like an obvious idea.

I'm not going to comment on the subject matter of this article, rather I think it's worth pointing out that we need more articles like this, investigating corrupt, shadowy organizations that are ripping off innocent people.

In fact, it would be nice if our journalists looked into some American corporations the way the Economist investigated Queensway.

Kudos to the Economist for doing reporting the way it should be done. Let's hope they continue pursuing this. This is journalism the way it should be done.
I'm not cyclical - or cynical (?) - about the experiences of those who have done something impressive or who have something interesting to say...

Years of attempting actual self-improvement do make one weary of hearing people praising themselves for doing stuff that isn't very profound or impressive. Sad to say, the experience of actually improving yourself by doing something difficult involves regular meetings with the realization that you aren't as smart as you thought you were, or as organized, or as persuasive, etc.

Constant struggling against your own carelessness, partial understanding of your field and the limits of your intelligence doesn't usually lead to this kind of half-smart undergraduate self-congratulation. Those who aren't struggling are either going to be rampaging, obvious successes, or are comfortable and smug exactly because they're not doing anything all that hard.

The original guy was resolving some problems in a team of devs at Accenture, not putting a man on the moon or sequencing the human genome for the first time or building Facebook or whatever.
