A friend shared this story (from a different link posted by Mashable) on Facebook, and I asked then how we really know how well the students are picking up what knowledge of what topic through this means. I see, going back to that link (the same text appears in your link),

"In an interview after his talk, Negroponte said that while the early results are promising, reaching conclusions about whether children could learn to read this way would require more time. 'If it gets funded, it would need to continue for another a year and a half to two years to come to a conclusion that the scientific community would accept,' Negroponte said. 'We’d have to start with a new village and make a clean start.'"

I also noted in the Facebook discussion thread that National Public Radio in the United States recently broadcast a report about One Laptop Per Child in remote villages in Peru, where ensuring access to the Internet or even electricity was a difficult problem for the schoolchildren attempting to use the laptops. I think further research is needed before we can be really sure that dropping off the laptops next to groups of children in the Third World will genuinely result in learning gains for the children in the usual school subjects.

AFTER EDIT: An astute top-level comment below asks,

Nobody's actually there, so who knows what's going on?

And, indeed, I should have mentioned that to properly evaluate this project, you would not only need people in-country, seeing the children face to face, but you would have to make sure that the evaluators are familiar with the local language, as foreigners who visit another country without knowing the local language often miss many important details in their interactions with local people.

1. The clips are short because the user who clipped them decided to make them that short. We would love to see your favorite clips (and they can be longer than a few seconds)

2. We are debating putting pauses between the clips, it really depends what kind of video it is. The video title is viewable upon hover - perhaps we should put it at the top of the page?

3. Any designers that you know well?

4. Thanks! we would love to see you make a best of list as well!
Exciting times to be living in. The head honcho of materials has competitors! And no matter which materials win, we all win, as the boundaries of electronics as we know them are pushed to their extremes.

Silicon is a bitch. The equivalent doping density of silicon is something like the area of the United States, with 25 trees in it. Spread out, over the whole thing. That's what you target, and that's what we get because humans are awesome. But now we get something different. We get new materials that exhibit properties that we haven't seen before.

The nanotubes absorb IR. Awesome... transparent screens that make power (only at 1% efficiency, but it will get better). Still, there is a limit to how much power you can get if you're only able to absorb IR. So let's make it better, let's take Graphene (or nanotubes, although I'm not sure if they do it as well) and make the bandgap adjustable. It's like the "smart glass" (putting a voltage across a material 'scares' it into interacting with light differently) [1]. Now imagine we can do that with Graphene, but instead of just diffusing light, we can control when we absorb it. Put this on top of your tablet screen, when you're using the device, it is in IR mode, absorbing all the photons you can't see. When you shut it off, it starts absorbing all the visible photons, charging up your device. Put this material in your cars, keep the heat out of them in the summer while you charge your EV. On top of your house (although a plexiglas roof would be kind of scary).

The moment that we start being able to purchase the 'carbon train' is a great one. Technology is kind of a mixed feeling for me, it's so cool that we can talk to anyone, do anything (in imaginary land), but there isn't much environmental good that comes from it. Now you can use computers to do climate research or whatever, but we go out and grab the rarest materials to throw into our new fancy screens. Then we throw them away (eventually) when a newer, cooler one comes out. We are locking up all our of materials in electronic sarcophaguses that may never be separated again (at least until we get fusion and heat is free). I don't care how 'green' your laptop is, the amount of energy that went into making those teeny chips is absolutely ridiculous and I'm sure the 'energy footprint' of laptops is near the top of things we purchase. Carbon will change that though. It's plentiful. It's fast, it's new, it's sexy. It's different. We may need a little sprinkling of something special to make it really do what we want (hopefully not), but it's better in almost every way. It's going to blow our minds what the computers of tomorrow are capable of. Not because we know what's going to happen, but because the path we're headed down is going to be very, very rocky. It's time for a good electronic disruption.

Presumably if you're designing products that could cause that much damage if they malfunction, you can buy insurance against any resulting problems. Limited liability is a public subsidy for big business--it reduces the cost of inherently risky business activity by shifting those costs to the injured public rather than to the business owners. It's really arguable whether such incentives are needed and whether liability insurance wouldn't be a more appropriate measure.

Hi everyone. I've been successfully selling my document templates for the last two years. This is the first one that I think might be of real interest to the HN crowd. The original version came about because I was the founder of a startup and was bringing on an acquaintance as CTO whom I didn't fully know. And frankly, we didn't fully trust each other, so we wanted to find a way to protect our interests if things didn't go exactly as planned.

The result was this agreement, which although titled Memorandum of Understanding (aka Letter of Intent) forms a legally-binding contract upon execution. It helps to prevent co-founders from "screwing each other" over by stating exactly what will happen prior to the legal formation of the new venture. In fact, that saved me a lot of grief. My prospective new partner and CTO did not work out. She quit right before we incorporated and opted to take a payout as a contractor. This was stipulated clearly in the agreement, so we were able to wrap things up cleanly without bitterness and maintaining protection for my valuable IP.

I agree. If you truly want to pay homage, perhaps wording like "inspired by Buffer" would work a little better.

What if I copyright something?

The text I am typing right now is under copyright by default, if I write something particularly brilliant here, can I expect to owe a good deal of taxes?

If not, why not? Both are intellectual "property", and both clearly can have very real value. Why should unpublished books be any less taxable than un-implemented patents?

Off the top of my head, Canadian startups HootSuite(Vancouver) and Freshbooks(Toronto) are doing very well. Rypple was also Canadian, but was recently bought by SalesForce.
I liked Ulam's Adventures of a Mathematician.

William Poundstone's Prisoner's Dilemma is only partly a biography of von Neumann, still a good book. Gian-Carlo Rota's Indiscrete Thoughts is a mash of bits and pieces, largely about mathematical culture and personalities. I thought it was an interesting read.

What I would really like would be a serious tome on Claude Shannon, he plays a bit part in many, many books, but nobody seem to have written specifically about him and his work.
I don't see how Boost algorithms provide the aliasing guarantees you need to avoid invalidating iterators. It's a very difficult problem. Even if you use a library to pipe instances of your custom string class to cout and you trust that library, the method or function that sends your custom string class to cout could perform arbitrary mutations, which would invalidate the iterator.

For example:

#include <algorithm>
#include <iostream>
#include <iterator>
#include <vector>

class mystring {
public:
std::string m_s;
mystring(const std::string &s) : m_s(s) {}
};

std::vector<mystring> v;

void operator<<(std::ostream &out, const mystring &ms) {
v.clear();
out << ms.m_s;
}

int main() {
v.push_back(mystring(std::string("Hello")));
v.push_back(mystring(std::string("world")));
std::copy(v.begin(), v.end(), std::ostream_iterator<mystring>(std::cout, "\n"));
return 0;
}
OK side note: Anyone else use Adblock to remove that ugly fixed #getSocial div with the Twitter, Facebook, etc buttons? I do this all of the time to websites, wonder if others do too.

Likewise, and I expect it's due to the novelty of polite, reasoned discourse.
>>The thought of "middlebrow dismissals" came to mind when I saw the ensuing discussion. Now I don't think I fully understand what is meant by the term

It's a spin-off from the term "highbrow", which means "intellectually stimulating". http://en.wiktionary.org/wiki/highbrow

A middlebrow dismissal means you are giving it only a half-thought before dismissing it, as opposed to critically thinking about it from multiple angles and offering an opinion that can result in a highbrow conversation.
"Btrfs (B-tree file system, variously pronounced "Butter F S", "Butterfuss", "Better F S",[1] or "B-tree F S"[2]) is a GPL-licensed copy-on-write file system for Linux. Development began at Oracle Corporation in 2007. It is still in heavy development and marked as unstable. Especially when the filesystem becomes full, no-space conditions arise which might make it challenging to delete files" http://en.wikipedia.org/wiki/Btrfs

You are very brave. I don't dare to store my backups on a filesystem still marked unstable.
Prior art: Windows 1.0.

Microsoft even once gave a demo of how fast QuickBASIC compiled code was by writing a program that split the screen into quarters and showed different real-time data displays into each quarter. You could call that prior art, even if it weren't for Windows 1.
You can either use a timestamp (that is included in the HMAC calculation to ensure it isn't changed) to allow a replay-window (this is what AWS does) or you can utilize a NONCE value retrieved from the server before hand and recorded as "played" once it is used so no other requests can ever be sent using that nonce.

Except you did when you called them tax evaders.
For anyone that kept seeing "HMAC" and thought "What in the hell..." I wrote an article (stream of thought in story format) describing how you might try and secure an API call, how AWS does it and eventually how 2-legged OAuth can be utilized to do it:

http://www.thebuzzmedia.com/designing-a-secure-rest-api-with...

NOTE: This is written from the perspective of "My god, what does this all mean?"

NOTE #2: You can do away with almost ALL of this complexity if you just force everyone onto SSL connections, but then you have to be ok with the increased latency introduced connection-(re)negotiation; just depends on what your API needs to do.

NOTE #3: I think the title of this article is misleading... there is no security on an untrusted client using HMAC -- if your client knows your secret AND they are untrusted, then you have problems.

I wasn't clear from the article how the JS library running client side is adding the secret to the digest before sending the request to the server to verify and process.

For those AWS folks out there, that is what your AWS secret is used for -- your request, e.g.:
/ec2/launch?cust=bdillon&size=xl&quant=2&sig=akjDjlasdmnDASkljasd

to sign the entire request, so when AWS receives the request, the first thing it does is attempt to re-create the exact same signature using the secret it has on file for "bdillon" (or whatever customer-identifying info was sent)

This requires both the caller and server to know the secret and I am not clear on how filepicker is solving this from this article... very broad strokes, no specific impl details from what I saw.
In 5 minutes I created a zap that creates a text file in my skydrive when a github issue is created. That is absolutely amazing - this is a killer product.
you should start from giving some numbers i.e. you want it to work for 10mil documents, how ofter they will be updated etc.

if it's less than 1mil and they are not updated frequently, you should go for postgres and have some fun with SQL,

more data and increased concurrency means problems also in postgres, a lot of optimizing, materializing views and other fun problems to solve.

Good question. Why not, indeed? If you're stating that a property has a cash value, such as by selling it or suing for that amount in real damages, then why shouldn't you have to pay taxes to the government that protects your right to copy it?

Ideas aren't a naturally limited resource. It takes government intervention to declare that an idea is owned by one specific party. It seems only fair that the beneficiary of that intervention should be expected to support the government that makes it possible.

By the way, I have no problem whatsoever with property rights. Although I think software patents are BS, if the government says they exist, then they exist. I just don't think it's fair that these non-practicing entities are paying their fair share to support the system that's netting them a paycheck. Why would I have to pay taxes on a rent house that I lease out, but they don't have to pay taxes on a patent that they lease out?
Another step to reduce friction and increase productivity. Very nice.
Zapier is great, I use them to integrate DropBox with HipChat, and it was no trouble at all to set up. And that's what I'm looking for in a product, solves a problem, no trouble to set up. One of the founders was also happy to chat with me about the DropBox integration, which is nice - sign of good customer service to come.

I also integrate GitHub with HipChat, but don't need Zapier for that. Anyone else do any integrations with HipChat they find useful?
My fault. I completely misread your comment.
Does anyone else think it's a crime that Google, Apple, etc. avoid paying corporate taxes and they should be stopped?

These companies benefit greatly from public services like public transport, electricity, police, fire, roads, etc. but then use loopholes to avoid paying taxes for them.

At the end of the day, this just results in billions of dollars higher private profits and crumbling infrastructure and social services for America.

The only possible long-term outcome is collapse.

I presume you're familiar with conjecture, such that "if these hypothetical conditions were really true, then this would be a consequence".

If patents were appropriately labelled as taxable property, then they would be tax evaders (unless they chose to value that property at $0.00).
Ask HN: What SaaS customer service tool(s) does your startup use?
I am selecting a customer service workflow tool to help manage inbound customer communications. A small group of employees will be logged into this tool to receive questions via email, social media posts, and (probably) live chat from prospective and existing customers. The goal is to help maintain a record of all communications, ensure no messages "fall through the cracks", and help us measure our responsiveness, efficiency, and productivity as a service organization. The tool we select should ideally also help us generate and manage a knowledge base / FAQ site.

The candidates I have identified so far:

Desk.com (formerly Assist.ly) - $49/user/month
ZenDesk - $20 - $49/user/month
UserVoice - $15 - $35/user/month
FreshDesk - $9 - $25/user/month

Does anyone have experience using these? Your suggestions and feedback are appreciated.
I know for myself at least, upgrading to newer hardware is mostly a big distraction from work or whatever it is I probably should be spending time on. That said, I had a mini9 for a few weeks and typing on that tiny keyboard was pretty painful, so props to Joey for sticking with it.

If Joey is reading this... It sounds like you are living in a remote place. It'd be cool to see a more detailed blog post with pictures. Also as someone who has lived with a flaky dialup connection for a long time recently, I can highly recommend mosh. Setup irssi+bitlbee on a server running under tmux. Then connect with mosh and attach to tmux. This way you get reliable chat and irssi should set the important flag for the window, giving you notifications of new messages too. You can also configure irssi to mark you as away when you disconnect.

This is a point which often worries me, I decided to skip higher education to travel and began programming (professionally for a company) when I had just turned 19, now, 7 months in I'm starting to see that my friends who went to college and university are actually light years behind me when it comes to achievements so far.

It's a bummer that I'll probably never work for the Facebooks or Googles of the world, but there are always jobs going in tech and once you have experience, your education is pretty much irrelevant.

Your education shows your first employer that you are dedicated and know your stuff, when you go to your second job, it is your performance in job one which will instead be validated.

You're right, this is the real drag but is the only way to achieve this as neither facebook nor twitter offer a way to generate apps programmatically (understandably).

That's a reasonable alternative and something that one could get used to. After all, Vim and Emacs people have been rebinding Caps Lock to Esc/Ctrl for a long time. One possible downside is the extra strain that this would put on the pinky.

An alternative that I've been wondering about is key sequences (M x) for WM actions and key chords (M-x) for all other things. This seems possible to do in xmonad (last point in this blog post [1])
