Energy usage at night is far smaller than during the day, so much so that we have an excess at night because of all the plants with constant output. You can tell just by looking at how the power companies charge industrial customers. On a residential scale, they bill you per hour. On an industrial scale there are contracts negotiated and a big component of that is what time of day the power is used. Ski resorts run thousands of HP in water pumps and air compressors to make snow, and they do it at night mostly because they all have power contracts with lower prices at night.

Efficiently moving power from one place to another is the big problem - the 'smart grid' is forever over the horizon - but storage only becomes a big problem after we have switched a massive amount of our energy production to solar and we're a long way off from that. Until then we just need to build a better system to move power from constant output plants to areas served by transient power sources.

It has been done a /lot/ - http://www.google.com/search?q=%22instapaper+for+video%22

If anyone of the founders of these startups are reading this, I have an honest question - why? Is it because there really isn't oen dominant instapaper for video the way there is an instapaper for text? Is it you were unaware of the competition? Is it boredom? I'd really like to know what drives you to create it.
What kind of JS projects do you have? CS is certainly overkill for form validation but if you have 50+ JS files that all need to talk to each other, CS can help make things cleaner and succinct.
Throwing information (even imperfect information) away is stupid.

A falsifier to this proposition using the original question:

If I took thousands of people who self-identified as wearing white sneakers, and thousands who self-identified as wearing black sneakers and I looked at the occurrence of gout in those populations: what would I see?

Obviously one expects a stronger correlation with race based on the fact that members of a racial group are assumed to breed among themselves more frequently and concentrate relevant genetic factors -- if that's what we're looking for. But I suppose that's the point I'm trying to make: let's be clear what we're looking for.

Similarly for cultural factors like diet. But then again, why not cut straight to the dietary data?

In this case, you only get to rule out the genetic markers that are prevalent in both groups once you've established that they are indeed prevalent in both groups. And even then you're running a risk of false correlations for specific individuals because you started with a categorization freighted with a lot of non-scientific baggage.
I think you are missing the point in your shallow analysis
As I mentioned in another comment, if battery technology is super cheap then it benefits all power generation, even coal, because it would marginalize the fluctuating operating costs. Nuclear would actually be perfect because current nuclear reactors are kind of like diesel engines, they thrive when operating at a steady, ongoing power so we could fill up batteries all day and night.
Ha, your comment made me wonder momentarily if the essay was a work of post-modern art, subversively advertising the benefits of CoffeeScript through an implausible flourish of logorrhoea. If so: Well done, sir.

>> Then there was the time I wanted to hire my first full time employee. I was apprehensive to do it because I only had enough money to pay him for 2 months, unless I got another client fast.
>> “Worry about that in 2 months,” Dad said.
> Speaking from the perspective of that employee, fuck you.

Yep I agree that does sound a bit irresponsible, though realistically I doubt most employers have more than a few months salaries stashed away in their bank accounts to pay employees.

Better advice from his father would have been to wait till he at least got another client first, then he could justify getting another hire - if just to work on the new client project.
How I wish the Times would actually put in some technical details! If their aim is the transparent diffusion of news, they shouldn't shy away from technicals that maybe most people don't know. In fact, perhaps it's time more people found out about public-key cryptography, and who "third party" verifiers actually are. Put some due diligence back in the hands of the public.
Ask HN: How do you stay motivated when creating content in a vacuum?
I've started tinkering on a few web apps of my own in my free time. Currently I'm working on a bookmarking site a la Delicious or Pinboard. At first, working on features for myself was fun, but now I'm finding myself unmotivated with no active users. I have no delusions of grandeur; I never expected to get tons of users to sign up, but I hoped for few to impress and keep me going.

Whether it's about having no users for your app, no followers on twitter, or no readers of your blog, it's hard to stay motivated when you're creating content in a vacuum. How do you get past this?
The near-universal stance has been that monopolies are a natural byproduct of the free market, and not a "problem".

In my experience, this is quite a mischaracterization. The position isn't that monopolies are 'natural' and 'not a problem'. On the contrary, monopolies are seen as being extremely harmful, but also as products of government intervention and barriers to entry, not the market.
One of my favorite bosses was general counsel for a state government agency. She once told me that "no contract can ensure performance of someone of poor character."

Whenever I'm offered a contract, I boil it down like this: "Do I believe they'll hold up their end of the bargain?" If the answer is no, I do not sign the contract.

I had a Galaxy S 1 and the lag was horrible. HORRIBLE! I resorted to rooting and using a custom firmware (Darky's ROM, which was like getting a new phone). With my S2, the lag is no where to be seen. I've had it for almost 2 months now, and I love it! Everything just works, and as a result I haven't even considered rooting it.

Samsung has historically had great hardware products, and crappy software products. But at least with the SGS 2 they seem to have gotten it right. Time will tell if they are more responsive about Android releases, but to be honest I'm not that worried because it works so well out of the box.

I am trying to suggest that academics are deliberately trying to game the system. Only observing that if it were a simulation a rational agent would follow that specific strategy. Luckily, most people are not perfect rational agents and so science progresses faster. Sorry my comment came across that way.

The reason you won't see a bytecode VM replace Javascript is because bytecode is either interpreted (slow) or JIT-compiled (complicated but faster). If you go for speed and JIT-compile bytecode, why not just compile your source and dispense with bytecodes altogether (as V8 has done)? This gives other runtime implementers the freedom to choose whether to create an interpreter, compiler, or some other execution mechanism, and the programmers the freedom to code at a high-level.

Bytecode, as distinct from object code, is on the way out. Consider Javascript a portable high-level object code and move on. If you want other languages, compile them to Javascript. Semantic affinity between source language and execution environment (e.g. is "0" false, as mentioned elsewhere) is an issue you'll need to address regardless of whether you're using bytecode.

Also, don't underestimate the power 'view source' had in making Javascript perhaps one of the most widely-adopted programming languages in the world.
I wouldn't worry too much about that. IMHO Flash is already a moribund technology. 3D acceleration won't change that.

The real competitor here are native mobile applications.

Also, I have to wonder about the security implications of WebCL (not the C not a G), like malicious sites using idle GPUs for password cracking. That sort of thing.
“And what if the waste produced by such a reactor was radioactive for a mere few hundred years rather than tens of thousands?It may sound too good to be true…”

A few hundred years is a helluvalot. It may all in all be better than fossil, but definitively not too good to be true.
That's an excellent point. Every power source would be boosted by better/cheaper batteries, even coal, nuclear, and hydro. In fact it could actually hurt solar/wind because with lots of batteries you could rely on a much smaller total generating capacity equal to just a little over average power usage (since peak loads could come from batteries). So there'd be less demand for new capacity of any sort to be built. It would also improve the safety of fission power since it would likely be easier to provide extended electricity to the cooling system in case grid power goes down.
Why's that? I don't see them being any less trustworthy than say Yahoo, Google or Microsoft.
Yup.
It's not just based on bid though. They calculate your positioning based on your quality score as well.

This isn't anything that new. Pretty standard fare if you've got an account with a decent budget that wants to push out other competitors.
If you can code, you can use things like Titanium to port your web work into native applications.

This article is a bit late. Anyone who has been keeping up with the Diginotar etc stuff knows that:

1, Diginotar is dead in the water now (they've been effectively killed off by browser vendors)

2. The exact problem here is very well known. That is, the problems with the SSL system having trusted authorities, and the number of companies trusted to issue certificates. (any trusted company can issue a cert for any domain it chooses)

3. This problem has already happened before with other certificate vendors, the only difference here is that Diginotar is a small enough fish that browser vendors are reacting (see, for example: http://www.theregister.co.uk/2008/12/29/ca_mozzilla_cert_sna... in 2008) Oh, and that Diginotar was silent on the breach.

And I like his boasting...sounds to me like a misquote or a script kiddie.
Yeah, he has really good descriptions of the various algorithms, with examples.
I really don't understand this obsession with shoving everything into the browser. In native applications 3d graphics are great for games and certain scientific applications but camera control issues etc make them too awkward and confusing for almost anything else.

The UI demands of games seem to me to be strongly at odds with the UI needs of just about every other kind of app. I wish all this effort was directed instead at making HTML5 less painful for laying out information in an elegant and straightforward way. CSS still leaves a lot to be desired in this respect.

I never cease to be amazed at how honest and forthright everyone in the (top tier) of the startup industry is, vs. the entertainment, government contracting, small business, etc. space. To say nothing of finance or politics.

That silicon valley and tech is taking over the world might be a result of this, but in any case, it's better for humanity.
Why isn't there an enterprising law firm going through the credits of all the Star Wars (and similar-vintage films with ongoing commercial potential), contacting every person on the list, and telling all the retired ones "There is a pot o' money with your name on it if you sign these papers which let us sue them for residuals on your behalf."?

I have to imagine that the legal strategy required there is a for loop with half-dozen templated documents: "Settle with $CLIENT regarding the residuals from the production of $FILM or in discovery we will subpoena all of $FILM's books and hand them to the forensic accounting department of $BIG_FIVE who will describe in vivid detail how they are an utter fiction, resulting in $DISTRICT_JUDGE issuing a judgement in excess of $GUESS against $YOUR_COMPANY."
I thought they made that switch somewhere around 1996-2000 when Steve Forbes ran for U.S. president (and I still read the paper edition fairly regularly). I haven't read it since, though they do have at least one good blogger these days (who I subscribe to via their personal site's RSS feed, which they've redirected to their Forbes RSS feed; I still don't visit the site).
Before you go to sleep write down on a post it note ONE thing you want to get done and put it on your monitor. Tomorrow first thing work on that ONE thing and get it done. After a while add one more additional thing to have TWO things to get done tomorrow. And finally once you've mastered completing two things a day, add another for a max of THREE things. Good luck!
The problem is, on his profile info, the "Project Manager of our Company" is clickable and when you click it, it goes to our FB fanpage. It means, everyone can write any company name, and select it if there is a fanpage of this company. And noone controls it if it is true or not. There is even no accepting question for FanPage owners if he fake is or not.

When someone have a clickable info with logo it looks very professional and true.

Skype was Private Equity, not normal VC/founder/team terms.

very rarely do founders fuck their employees over, relative to how employees are treated in most places. Founders vs. VCs or Founders vs. PE is more common, but founders at a late-stage company should be a lot more educated and resourced.

It's mainly at the idea to startup to series A stage where people are fairly universally honorable, at least among the top people.
When I heard that Dropbox had raised a very large round, my first thought was that Apple or MSFT was trying to buy them up, since both are trying to kick-start their cloud storage offerings.

IMHO, its too bad, since I would of really loved to have seen Dropbox more tightly integrated into iOS. (iCloud will be and it might be my replacement for Dropbox). Though for sharing, I don't think iCloud will have those features for a while.
Uh, no.

Prices did go down 30%, but it took ten years, not one. http://gigaom.com/cleantech/solar-costs-dropped-30-over-last...

This is my problem with solar energy. It's getting better. It isn't price-competitive with coal yet. There are already lots of niche applications. But people can't maintain a healthy skepticism about it because it's such a feel-good technology.

To wit, the US government loaned $535 million to Solyndra at about the same time LBNL released that report. Now they're broke and the FBI raided their offices a few days ago. Where else could a company borrow half a billion dollars without ever showing a profit?

In comparison, the entire projected cost for the solar updraft tower that the Southern California Public Power Authority is building is under $30 million.

ETA - No replies yet, but plenty of downvotes. I hope to be corrected if I'm wrong, of course. I tried to find credible sources for what I've said here. I can't source my claim that solar power is an issue where people pay more attention to feelings than facts. You can't prove something like that. But people are downvoting, and they aren't answering...

Here's another really old Tetris sample for pygame I wrote half a decade ago (174 non-blank lines):

http://web.archive.org/web/20060208230531/http://www.cryptop...

Looking at it now, the code has some warts. It was written on an airplane ride and I just noticed I mistakingly left out S and Z tetrominoes. Oops! It's also interesting to compare the difference in block representations with my C program; I definitely think my C representation (offsets rather than masks) is cleaner. With the Python mask representation, I use a nested list transpose to take care of rotations: list(reversed(zip(*shape))). While that's a neat APL-style idiom, Python isn't really giving me any leverage over C. For example, for clearing rows in Python I use list slice lvalues. Those are useful, but here C gets the job done just as conveniently with memmove and bzero.

Anyway, it could be a lot better, but it's still simpler than most of the tutorial-style game samples littering the net.
