Facebook founder loses $3B in 48 hours
Web App similar to the iPhone App Snapchat 
I've hacked together an app that does something similar to the popular iphone app Snapchat. It shows an image temporarily, after that, it is gone forever. I'm using RoR, Javascript, Ajax, HTML, CSS.

I'm still stuck on how to block screenshots. I think using key events I can block it on a mac but not sure how to block it on a windows computer.

Any feedback would be great :)
Or maybe they are glad to leave marketing behind and focus strictly on their core competency. But in any case, yes an entrepreneur might not do well within a larger team, but that's a judgement call for the acquirer to make. Certainly seems like no more risk than a great interviewee becoming dead weight on payroll.
The educational establishment won't "buy in" it Khan, just like the traditional encyclopedia establishment didn't "buy in" to Wikipedia. But change will happen regardless because the users of education, the parents and students, will ask themselves the same question that the users of encyclopedias asked themselves: "Why are we continuing to pay for the same old product when a much better product is available for free?"
That's the beauty of how we are going about this. If our campaign succeeds, there will be at least 9,999 like-minded individuals with you on day one!

Besides the main contenders, gmail, yahoo, et al. The thin-client email app ecosystem seems even worse than the thick-client app ecosystem. AFAICT.
Rogue state. Imagine if China had done this to a US company.
That isn't the work I'm talking about. I'm talking about assignments and exercises. The things you're suppose to be doing in college.
I find an empty stomach, similar to alcohol, allows it to work to full effect.
Why every office should have a nap room.
A few years ago I traded being permanently sleep deprived and drinking tons of coffee (which I love) for always sleeping 8 hours per night. My productivity has been very consistent and stronger than ever since. No more boom and bust cycles.
I gave up caffeine a few years ago. I get far fewer headaches, and I've noticed while soldering my hand is now rock solid, no trembling.

For me at least caffeine wasn't giving me any kind of boost, just fighting off the withdrawal symptoms.

I think that's a problem for most people, they think coffee is giving them a boost, but really it's just that they feel relatively better because without it they are suffering withdrawal symptoms.
Senior linux system administrators are in very short supply. Companies have given up training people for that kind of work, schools don't teach it, and most of my sysadmin friends migrated to management or dev over the past few years. I've been looking around for a new gig in San Francisco (not south bay) the past month and sometimes it feels like I'm the only candidate and there's all these companies that can't find people.

It's nice feeling wanted but I won't do the work of five guys by myself and be the only one on call for years at a stretch, something will have to change soon. I wish Google would adopt that Lee Iacocca philosophy of training people specifically to spread their way of doing things across the industry, at least there'd be competent mid-levels around then, but they just churn those people on 1 year contracts like everyone else.
One thing that a lot of these kinds of articles don't mention is that tolerance effects in drugs tend to be at least somewhat dosage dependent, and there is some evidence that this is the case with caffeine[1]. Look at amphetamines, for example; at large doses they have a large tolerance effect and are highly addictive. At small doses the tolerance effect is smaller, and they are non-addictive, yet still therapeutic against disorders like ADHD.

It's reasonable, therefore, to suppose that there should be a "sweet spot" for caffeine use, where the tolerance you build is small, but the effects are still significant.

It's also worth mentioning that "tolerance" is not an all or nothing thing. With nicotine and amphetamines, there is a tolerance effect, but some of the effects of those drugs actually become stronger with regular use (and this is believed to play a role in the formation of addictions to those substances)[2]. So while tolerance and withdrawal are real problems, it is a myth that addicts merely return to the baseline in all respects when exposed to the drug they're addicted to.

In any case, if you are bothered by caffeine side effects, you might want to get some theanine. It's cheap, relatively flavorless, and when used in a 2:1 ratio with caffeine, it's been shown to reduce the side effects of caffeine[3], while adding some other cognitive benefits besides what you get from caffeine alone[3][4].

Correction: you think if you do it won't cost those responsible dearly. My bet is you don't fuck with the Internet.
It seems to be that America is slowly becoming less free; considering factors such as Obama's domestic assassination program, federal wiretapping and more. As an American, I still acknowledge we live in among the freer societies of the world. I still can't help but wonder why the government is increasingly imposing the way it is, history has always shown that repression of almost any form backfires in the long run.
What happened to the clean branding that the current splash/Kickstarter campaign page have? The textures here are really distracting, even in 400x300.

That does not make any sense. Yes, arguments should matter by their own merit, but why would we bother with a list of arguments curated by somebody that is inherently a fraud?

With the same logic you can spent a full life carefully dismissing idiotic arguments on Youtube.

Who has time for that? So his comment is very relevant. The submission itself is tainted, and goes on the "maybe ill look at that, if i live forever" pile, together with racial arguments, conspiracy theories and the political spin city puke.
"Most of the best guides don't know how or can't market themselves, especially online. Most potential travelers don't know where to start to find them or don't trust themselves to find the right one.

Thanks! That's exactly our goal -- you've pretty much captured the problem we're trying to solve.
Google might have also bought some of the code.
No sweat, thanks for the gist, I'll add it the repo. I'm impressed, actually, if it brings the runtime under a second, because only a couple languages managed that.

The act of finding the correct strictness hints seems a bit like black magic.
Aha, I didn't understand at all before your edit (no offense :P), and I think you have a good point, but it is actually on the "pro" side for approaches like Winer's: the hypothetical "Twitter-like ecosystem" is targeting now, just like Twitter (less the realtime-related problems, sadly), but is set up to continue targeting "now" once nobody uses Twitter, even during the transition period!
This job is done by a Chinese "agency".
Traditional schools are built on an industrial batch model where the goal is to get a certain percentage of the class to basic competency. So students are grouped in classes, taught for a semester, graded, and then moved on.

The Khan and homeschool model, in contrast is the mastery model. Students are individually taught at their own pace. They are not graded and pushed on. Instead they keep learning a topic until they know it. In traditional classroom education, the learning is variable while the time to learn is constant. Khan makes the learning constant and varies the time. Some students will learn faster than others, but all students learn to a high standard.

Khan is not just delivering a better classroom. He is offering a wholly different model of education.
Last night Twitter unveiled their Olympics site.

Thanks for the feedback. The app is nowhere near finished, but we just wanted to post initial screenshots of a live app built on our API.
Good to know I got the point! :P Can I ask about your thoughts on StatusNet?
This has nothing to do with coffee and much more to do with regular sleep.

Neither of which are mutually exclusive.
Just seems like a confusing mess to me, with controls on each video and sync'ed controls on the side. If you can't hide the individual video controls, I'd merge the two videos into a single video stream before embedding it. That's how bad I find the UI. Have you sat any people down in front of this thing and watched what they clicked? First thing I did was hide that huge sidebar covering the video, then I messed with the individual controls and figured out that is not good, then finally brought the sidebar back...
One wonders what prevents the government from simply providing notice to Megaupload's counsel, which does after have power of attorney and is thus presumably empowered to take notice as well. I haven't studied the ins and outs of criminal procedure though.
I just downloaded the PayDragon app, and the "Discover" feature is one of the more intriguing aspects. I regularly look for interesting, convenient food, and aside from walk-bys, it's not all that easy to find in my neighborhood.

EDIT: In Manhattan, however, PayDragon only has one restaurant in the "Discover" category right now—it's Murray's Cheese, which might be delightful, but it's also somewhat far and not especially appealing.
Don't extrapolate too far. Wait for the Judges ruling first.

It's the job of the prosecutor to claim anything and everything (as long as it's the truth) and let the judge sort it out.

I keep switching between tea and coffee. I like tea more at the moment (green, white, black, pu-erh, sometimes herbal).

There just seems to be a wider variety of teas that I can switch between. I don't do it for alertness or withdrawal symptoms as much as I do it for the taste. Coffee to me, while tasting good, more or less seems similar (short of changes in roasting levels).
Given that this case required the cooperation of Hong-Kong police, they are now sort of entitled to.

Derby is absolutely amazing, but when I tried to build something with it 6+ months ago, I was stymied by the complete lack of authentication features. The majority of apps (and games) require the ability to show one user X+Y and another user Y+Z, and it seems like a ludicrous oversight.

Looking now, I see a vague reference to server-side logic (in the context of recommending against it!), but nothing about auth specifically. Has anything changed or improved on this front, or are there any plans to do so?

The importance and effectiveness of caffeine has a lot to do with your job and lifestyle. If you are a mostly sedentary computer worker, the lack of blood circulation from sitting all day is going to make you super tired and slow your brain down. If you're a more active person, either from daily exercise, standing up at work, or a more physically strenuous job you're going to have more maintained energy levels as your body consumes and uses food and pumps blood harder.

Caffeine in either of these situations is going to enable your body to squeeze out more energy but for the person with more active blood flow and metabolism it's probably going to be overkill and they'll be able to get through the day without constant yawning. On the other hand, if you sit for 8 hours you're going to feel almost extreme tiredness towards the end of the day especially if you over consume for lunch.

I guess what I'm saying is that if you want to have a good energetic, drug free day, you should be taking steps to eat well and keep your blood flow up.

Also, when considering the effects of drugs on your body, all anecdotal evidence, like this comment, should really be regarded with extreme scrutiny if not disregarded all together. A good place to begin learning about caffeine would be here: https://en.wikipedia.org/wiki/Caffeine#Health_effects
Thanks for sharing. Note Apple increased the size limit for OTA app installs earlier this year from 20MB to 50MB (the article was written in July 2011).

There's also a lot of interesting data coming up mildly positive on Caffeine health benefits in the literature.

http://www.ncbi.nlm.nih.gov/pubmed?term=caffeine%20cancer
http://www.ncbi.nlm.nih.gov/pubmed/21907331
http://www.ncbi.nlm.nih.gov/pubmed/19581722

Moderate caffeine intake is on track to be firmly in the green for most people. However, not everyone metabolizes and reacts to it identically, so the author of the article in question may be one of those people who does not get a lot of benefits.

But there is this funny idea floating around that caffeine is carcinogenic and long-term use may cause cognitive impairment, and there is very little evidence for that.
Thanks for clearing that up. Indeed the GPL forbids further restrictions on the rights it provides. Which makes it incompatible with app store distribution.

I though I saw something in the App Store rules as well. I double checked and they mention the GPL and basically say that you should respect FLOSS licenses such as the GPL and avoid those licenses that would have an effect on Apple's code.
Unfortunately this has been true for a while. For example, having drug-trafficking charges against you dropped doesn't automatically release all impounded property. There is some right to due process, but its precise extent is unclear: there has to be some kind of hearing at some point, basically, in which the seizure can be challenged. But it's actually possible for the government to seize the assets permanently after such a hearing, without a conviction.

nReduce is remarkable. I've participated every week for the last seven weeks, out of curiosity mostly. Several things have surprised me:

* The sheer number of teams who joined up (300+ worldwide and 100+ in SF): There are a lot of people who are eager to participate in a startup incubator.

* The motivation, ability, and intelligence of the people I've met: These are the smartest and hardest-working people I've encountered in years.

* The power of self-inflicted group pressure to drive productivity: I consider myself highly self-motivated and productive but I stepped up my game knowing my peers were reviewing my performance via the nReduce weekly video check-in tool.

nReduce is a work-in-progress and I think we all realize Joe Mellin and Josh Schwartzman are making it up as they go along. I heard someone grumble that they didn't get pizza and beer at every weekly meeting. They missed the big picture. nReduce is a social experiment that is taking flight because there's a need and desire for startup aspirants to join together for mutual aid. It styles itself an incubator, it's a big meetup, it's an online social network. I see it as something more, though, as a unique form of social organization for smart people who are helping each other create businesses that deliver value.
Have you fixed it? I have the same problem and I'm still looking for a solution.

I believe that auth is in Derby, although it has just yet to be documented formally...
Surprised that there are no comments here in favor of his premise: I for one am getting sick of constantly hearing about the next "social local mobile app that helps you rate the experiences of friend's of friend's cousins" getting funded.

I know I am not the only one: the Founder's Fund's tagline goes something like "We asked for flying cars, we got 140 characters."

Yes there is value in Facebook and Youtube etc., but he makes a good point that most of these companies got the formula just a bit more right than many other competitors with similar ideas. It is often just as easy for them to get the next iteration wrong and lose the consumer. Instagram was the perfect example.

There isn't anything necessarily wrong with this, I take a somewhat agnostic view of it all, if you can make money doing it it is obviously valuable to someone. And perhaps it's easier. But the companies who are doing something more concrete and valuable should be getting more attention in my opinion, and the investors should be focusing on them more.
The idea is the computer will wait in line, not the person.

i.e. you still have to wait for the food to be ready, you just don't have to do it in person.
http://en.wikipedia.org/wiki/Health_effects_of_coffee

From that we learn that coffe is linked to increased levels of smoking and lack of exercise -- AND:

A May 2012 study by the New England Journal of Medicine found that, during the course of their study, coffee drinkers "who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study."

That combination seems to imply that coffee in itself is healthy.

Besides, we Scandinavians drink the most coffee on the planet and we are are are are healthy as He He He Hell, but a bit twitchy. It is a totally false rumor that we die if our blood turn red.

Edit: I should add that no chemical is good for everyone, not even caffeine.
Coffee has as much variety as tea. Any good roaster can show you the difference between, say, a Kenyan and a Costa Rican. There's also more variety in coffee preparation with varying results. Tea steeping is a lot more 1-dimensional.

But what Tea has in quantity is L-theanine, which has additional stimulative effects on top of caffeine. A lot of people prefer it to coffee for stimulative effects because of this added kick.

To summarize: a company is genetically either an innovating "Breakthrough"(Intel, Texas Instruments, Google) or a sexy and shallow "Best-Of-Show" (Zynga, Facebook, YouTube).

As others have pointed out, false dichotomy is false on several levels.

1) Even Breakthrough companies go through cycles of stagnation and innovation, especially in the tech industry. Best-Of-Show Apple in the 90s compared to Breakthrough Apple in the 21st century. Breakthrough HP in the middle of the 20th century versus Best-of-Show HP today. The list goes on and on.

2) Best-Of-Show companies often are innovating within their own domain. Facebook today is simply in a different ballpark than 2003 Myspace with sharing, groups, pages, etc.

3) Best-Of-Show companies can cause massive disruption in adjacent verticles. Try finding a news station (online or offline) that will not reference discussions on Facebook/Twitter.

The author repeatedly claims he is not making "a moral judgment", but that is exactly what he is doing. His opinion is that innovation in hardware/algorithms is more important than innovation in social/games. I am not sure why he is afraid of speaking directly, but hiding arguments in false dichotomies isn't helping anyone.
You mentioned that the LGPL library may be further distributed. Can others further distribute the object files and the build scripts also though?
Facebook's Bigger Mistake Would Be Obsessing About Wall Street
Right, except that the problem is the client drops and you have to jump through a ton of hoops to get back to the service, which terminates the connection as soon as you drop. Its not really an issue of 'lag' as it is 'not recovering'
There are some good and bad reasons for this. For example, the deregulation of electric utilities in California in 1996 was an epic failure. Part of that was due to the design of the deregulation scheme, but a lot of is was attributed to the perverse incentives of the free market.

Do you trust Twitter? Do you believe that they will have the same motivations that you do, as an organization? I believe that is the fundamental question you should be asking.

I'm not really sure it matters where the users are. Ideally in a well designed system/protocol, it shouldn't matter. Email solved that problem 30 years ago.

> Ultimately, these companies wouldn't invest in training if there wasn't a return on that investment.

Possibly, but its hard to see a ROI in this situation considering they are paying for training and giving the kids a full-time job, possibly with benefits. That's a couple thousand a person in training + 44,000 salary + a couple thousand in benefits and possibly a union membership. I don't see how there is cost offset over converting engineers who have a base knowledge. Not only that, where are they going to go if they lose their job?

We're also talking about high school students here. They've had stuff taken care of for them all their life (baring extenuating circumstances). Not exactly the most responsible bunch I would guess.
America was never as free as you thought it was, there was just no way to thoroughly challenge this undeclared freedom (and there definitely was no way to publicly do so as well).
