I think it's been changed. There also were no underlines beneath the links before.
The article focuses on "missing pixels" which doesn't have much to do with the original Candes paper. The usual setup for compressed sensing is that you're sampling the entire image one coefficient at a time in some "incoherent" basis (ie, noiselets). Thus, every little spot of Obama's acne may very well be reconstructed-- though more generally you're right, if the image is too sharp then something gets lost.
I'm assuming it's more along the lines of 'no personal debt'. Many single founders, as they typically have trouble finding funding, find themselves taking on personal debt to fund the business.

I'm not sure we are immunized against ghettos. Ghettoization has led to violence/ethnic cleansing out on the west coast (Mexicans ethnically cleansing Blacks). In my neck of the woods, there is an Arab ghetto in South Paterson and an Indian ghetto in Edison.

Regarding 2, it's not so much about liberalness/open mindedness as it is about the fact that in the US, you choose your own destiny. Regarding the south, as far as I know they don't tend to try to prevent their daughters from getting educated/working in order to keep them under thumb (for example). I suspect (1) is more an issue for them than (2).

But then again (assuming you aren't from the US), do you really want racist American southerners coming to your country?
So many euphemisms...

One of my least favorite parts of working at a large company is being referred to as a "resource". Library books are resources. I AM A HUMAN BEING!
You're not exactly making assumptions about the level of detail. You're making assumptions about the compressibility and entropy of the data. A circle requires the same amount of data to represent whether its radius is R or 2R[1]. L1-minimization tries to find the smallest number of circles regardless of size, whereas traditional compression methods look for the largest circles regardless of number. It attempts to minimize the entropy of the result image (roughly), and all real pictures that aren't literally static have low entropy.

A saw a presentation on this technique in college. Some of the details I saw escaped me, but one thing I remember is that the L1 decompression is optimal when it is "orthogonal" to the compression that it is reversing. Fourier-based compression schemes (including JPEG and MPEG, and even MP3) are "orthogonal" in the correct sense because they select based on size, preserving large structures better. Random sampling is "orthogonal" to basically all compression schemes, and tends to select more information from large structures as well.

With a high-res bazilion-dollar space telescope, you're not going to throw away 80% of the pixels and reconstruct an approximation. Rather, you'll take all of the recorded pixels, and then reconstruct even more impressive astronomer porn at five times the resolution!

[1] Well, close enough. If you store the circle as the (x,y) of the center and an integer radius R, then 2R takes 1 more bit. Storing R as floating-point means no difference. I don't know about other representations. Anyways, the point is, the image size of the feature is not strongly coupled to data size of the feature.
I'd say it was indirectly because of that. Economies of scale have made growing food far easier and cheaper, which allowed humans to spend time on other things, like discovering penicillin. We could probably go back to buying food directly from the people who grew/raised it without sacrificing much of our current quality of life, but the money we'd spend on that would've been spent on advancements in other areas of life. At this point, such a shift would probably be a net positive in terms of improving health in the near term.
This is definitely true to a certain degree, which was one of the points of the linked article. But it's still lamentable that some solo-founder startups that could benefit from funding will fail to raise money because of irrational investor bias.
Same here. I can only recommend to learn you a functional programming language for greater good. I love every minute I spend writing Haskell code, be it a simple console application or something more complex. It's really fun, interesting and educational, and I'm only at the beginning :)

And a lifetime of observations tell me that men in general are greater risk takers and more competitive. I cannot prove my thesis with 100% rigor, but it's the best explanation of the facts that I've got.

It's kind of embarrassing to me that whenever these issues come up on forums like this, people immediately start getting into amateur evolutionary psychology.

There's never going to be perfect data on either side that proves any of this. We'll never know for sure how much of the male/female divide is genetic or environmental. Neither sociology nor psychology is a Popperian science. So all we can do is combine knowledge of what science might apply, personal observations, stories from others, personal experimentation, readings from histories, etc, and make a judgement. In a word, we use Phronesis - http://en.wikipedia.org/wiki/Phronesis
How The Photonic Fence Works
When you (as NBC) have payed $800 million to get coverage, I imagine you can gut and rewire/install anything you like in the facilities, and even give your employees jackets that say IOC on them.
IANASE[1], but this seems a lot less secure than letting them keep track of your credentials. It seems like an open invitation for man-in-the-middle and phishing attacks. Training your users to (thoughtlessly) enter their credentials over and over seems like a really bad idea.

But that's illegal. :(
For the opening ceremonies, I watched both the CTV coverage (first) and then later in the evening the NBC coverage. I was pretty shocked at the differences -- the NBC coverage was terrible: Horrible camera angles, bad panning and zooming, almost no close-ups on single performers and way too much on group performances, terrible lighting, the audio cut out twice during a major performance -- you name it, it was poorly done. Watching it on NBC, you'd think the entire opening ceremonies was 2-bit production. I was actually surprised that there simply wasn't one set of cameras for everyone involved.
Yes, online recipe ratings are broken, which is why I don't pay attention to them. Of course, I'm a fairly good cook, so I know how to look at a recipe and tell whether it makes sense or not. Often, I'll end up with 60% of one recipe, 15% of another, 10% of a third, and 15% my own experience to pull together a recipe for a dish I want to try to make.

If you're looking for something on how to make a dish (like I did recently for baguettes) and find several recipes to choose from, I find a few things make it easy to choose from:

1. Real, individual ingredients are better than composite ingredients (that is, flour, baking soda, oil, etc. rather than Bisquick™).
2. Simpler recipes are usually better than complex recipes, especially if you've never made the dish before. There are exceptions, of course. (I'm certain that the King Arthur baguette recipe that I found would be better than the one that I tried, but it requires making a sourdough starter some fourteen hours in advance. I will try it some day.)
3. Well-written descriptions suggest better recipes. This is a bit like code comments, though—there is such a thing as too much description.
4. Recipes that depend on exact timing of multiple pots and pans are probably not a good idea to experiment with if you're not already good at making similar dishes.

That said, I'd pay attention to recipe ratings if there were only two yes/no questions: I made this; I'd make it again. Report the resulting value as a simple ratio of (repeat)/(made once). Seriously, I don't make recipes more than once if I wasn't enthusiastic about the results or weren't convinced that I could make it better by changing the ingredients or cooking instructions better. I don't know anyone who does. Star ratings are a waste of time.
But not immoral. (IMO.)

In this particular case especially it's hard to object to a torrent. It sounds like he buys TV, and there are just some gaps in the coverage offered, and he'd only be using torrents to help fill in the gaps. What harm does that do?
Do you rank better for pages you do compete on head-to-head?
This article is a dup of: http://news.ycombinator.com/item?id=1124782 and I repost my comment from there:

The paper linked to is a low quality imitation of the current literature. Among its flaws it has the common fallacy that if a problem has a large number of states than inspecting all the states is always hard.
I strongly recommend instead some of the interesting actual work on Nash Equilibria and Correlated Equilibria:
"Nash equilibria: Complexity, symmetries, and approximation" Contantinos Daskalakis, Computer Science Review (2009) vol. 3 (2) pp. 87-100
"Computing Correlated Equilibria in Multi-Player Games" Christos H Papadimitriou, (2009).
> all the same stuff as most other languages, but then there's this whole other layer of knowledge (mostly mathematical problem-domain knowledge) you have to add on before you can actually claim to "know" Haskell.

That's just computer science -- a bunch of CS stuff is easier to express in Haskell, so we do, but it might need some background.

> here's how to do in Haskell the stuff you already know how to do in Ruby

Try a different tutorial. Maybe: Real World Haskell?
The events shown on NBC are so heavily edited, overproduced and filled with backstory glurge, it is like watching a made-for-tv movie about the olympics instead of the olympics themselves. Bah.

well yes. I mean, my company would probably also benefit from investment; it is a rather capital intensive industry, after all. In my case, though, I think there is at least as much irrational bias on my end as on the investor end.
I believe the only other time I'd been to killerstartups.com was for a bio of Gliffy, another online diagramming tool. Having used both of these, and another 1/2 dozen other competitors, the web based diagramming tools just feel not to offer any serious competition to either Omnigraffle or Visio.
I thought about this a while back too, but convinced myself not to do it because I didn't think people would admit to using it. And if not, then it couldn't even spread by word of mouth.

But it looks like that's not the case.

I was following the 2002 World Cup fairly closely and watched on Univision for a different (but related) reason: they actually broadcast the games when they happened. 4 in the morning? No problem. There was no question of knowing the results before the broadcast, which was already eight years ago a typical problem for those of us with decent internet connectivity.

You're missing some basics. For example, I can find out easily what version of Apache/OpenSSH etc you are running (Apache/2.2.11 (Ubuntu) mod_ssl/2.2.11 OpenSSL/0.9.8g mod_wsgi/2.3 Python/2.6.2, OpenSSH 5.1p1). Please turn off the banners that advertise these things. Also, don't run your SSH server off of your Apache box. And use public keys instead of passwords.

You can consult this hardening guide written by the NSA for Red Hat: http://www.nsa.gov/ia/_files/os/redhat/rhel5-guide-i731.pdf. Even though you're using Ubuntu, the same general principles apply. Follow that guide to the letter and you will be secure enough until you can afford to higher professional pen testers.

Note that the NSA guide doesn't cover web application security, so you'll need to take other steps to ensure that part of your business is secure.
On the other hand, if I were to have brain surgery in 2030 I probably wouldn't want the world's best surgeon from 2010 to time travel and do it.

I agree with your broader point, but your specific example is unfortunate. Surgery, and brain surgery in particular, has a lot more in common with the 19th century than the 21st. A disturbingly large amount of brain surgery is still accomplished via drill and very tiny ice cream scoops. I'd be surprised if that changes very much even in 20 years.
Yeah, this has led to the odd situation in AI that reducing to SAT is how you show a problem is easy--- there's a whole cottage industry of people speeding up algorithms by reducing them to SAT, and it's often seen as a promising result for your computational tractability if you can do so.

(And the biggest problems, when they arise, are usually actually in the reduction itself---it takes too damn long to write out the SAT problem. Once you've got the SAT problem written out, solving it is rarely an issue.)

Mahalo is not particularly interesting, not particularly evil, he doesn't really do anything, and yet - we keep talking about him and putting his shit on the front page of hacker news.

I said that the inference to reproduction strategies was hypothetical, not the numbers.

As you say, there simply isn't any good evidence available for any position in this domain. For this reason, I don't see the point in making these highly speculative connections between reproduction strategies and startup gender balance. It only serves to cloud the issue by offering a pseuoscientific defense of the status quo (and by going off on a hell of a tangent).

The whole thing is a complete distraction from considering the issue in a practical way. If we actually got significant numbers of women in these positions, we could find out whether or not they were inherently unsuited to them.
The iPad Will Rule the World
This is pretty much what happens.

There's an IOC subsidiary called Olympic Broadcasting Services (OBS), which has crews/cameras/directors at every session of every event. If you're watching an event happen (as opposed to an interview), there's a 99% chance it's coming from an OBS camera. If the shot is coming from a site-specific camera - like the track-side camera at speedskating or the overhead curling shots - it is coming from an OBS camera. OBS cameras are the only ones allowed to go into the field of play; all other cameras have to stay on specified media risers outside the competition area.

When you watch an event on CTV, you're actually watching the OBS feed (with OBS graphics) overlaid with a CTV-supplied commentary track - the only sound OBS supplies is the ambient environmental ones, and it doesn't cut to any interviews or anything. Those of you who watched the Beijing Olympics on the CBC website may recall that there were eight or nine feeds available, but only one of which had CBC commentary. The commentary-free ones (which also didn't have commercial breaks or explanations) were the raw OBS feeds, without any additional CBC editing/directing.

When a broadcaster pays for exclusive national rights to the Olympics, one of the main things they're paying for is exclusive access to the OBS feeds. As for why they don't sell that feed to multiple networks? I assume they've worked the math and determined that they'll make more money by selling it exclusively, as opposed to cooperatively.

> I don't understand how people keep failing to understand monads. Maybe it's the line noise operator `>>=' ?

For me at least, the mathematics line-noise is a bigger issue, and it made more sense once I ignored it. As a programming construct, monads seem quite understandable to me, even clever. But many of the explanations, especially earlier ones, started out with a type-theoretic explanation with links to category theory...

In particular, I was under the misimpression for years, because of it being presented that way, that monads were essentially of interest only for people who were hung up on type-checking: that they were a solution to how to make the type-checking go through on a certain class of problems, by lifting an underlying type into the Monadic type and getting it back out again. As someone who mainly uses dynamically typed languages, this didn't seem of interest, since in Lisp, I don't care if the type-checking goes through or not. It was probably years later that I figured out they had some non-type-related programming benefit.
Reading through these commends, it seems like us people in Malaysia have it better than you guys in the US. I've been a bit disappointed with all the attention paid to Ice Skating/Dancing etc. but for the most part, they've (ESPN) shown a good mix of the events going on in Vancouver.
A lot of people are expressing concern about having to give you their Gmail password. Have you considered implementing an offline scanner for desktop clients that would then upload the contact and frequency information to your severs through SSL? You could then overlay your services in Thunderbird's/Outlook's/Mail's desktop interfaces.

That kind of kills the convenience of the service, but personally I would accept that for increased security.
Before making such a drastic change, perhaps you can test your concept (increasing viewer-ship by decreasing the alloted time to view a show) by implementing a TV/Cable model.
Have a Regular time period that you air a new show (perhaps for 3 days).
Then put the video into "Reruns".
If you go to Mixergy.com, you will only have the Last 3 new shows + 3 random re-runs. This will bring old videos to the forefront again and will limit your supply which might increase the demand as people would be worried that they would not see a show until it happened to come back into re-runs. Also, would have people coming back to look what is being re-run that day in the hopes of finding an old classic. Then you can have the All Paid Access that give you access to full archives. However non-paid users can still get lucky and see their favorites in re-runs, however would be motivated to watch new shows before they go away.

You really think that unbiased data for an issue as complex and multi-layered as this is possible? There is never going to be a paper that proves once and for all that the best people to hire are white american males.

So don't talk about "we need the data" for situations where it is clear that there will never be any data. In such cases, just do what you feel is the right thing: if you feel your business will only do well with a particular type of person, stick with that type of person.

Personally, I found the argument as constructed convincing - intellectual diversity is neccessary. And a homogenous crowd is not likely to be intellectually diverse.

I have been cursing at NBC for their screwed up coverage for a week. It is really really bad.

Did you know for example that they have a channel called Universal sports that is owned by NBC and that is an over the air and cable channel that broadcasts nothing but sports. You would think that would be the perfect place to broadcast the olympic games. You know what they broadcast? They broadcast winter sports, but not the olympics. Instead, they have replays of winter sports events that happened months ago. So for example, while the men's downhill was happening and it was not being broadcast live by any NBC channel, that universal sports channel was showing an old replay of another men's downhill that was not an olympic event (it was part of the world cup circuit and happened several months ago). While the US women hockey team was playing without being broadcast anywhere, the universal sports channel was broadcasting a fricking documentary about the US women's hockey team.

I mean it is as if they intentionally want to piss me off.

Oh and dont get me started on primetime. First of all they take up half an hour of prime time coverage with a show that is about the olympics but does not feature any olympic sports. Instead it is a freaking infomercial about Vancouver and british columbia, and various random products, restaurants, that may have a minor connection to the olympics. So NBC is broadcasting infomercials in prime time that is how far they have fallen.

The actual sports coverage is so badly presented that you always know who is going to win the race before hand. That is because the idiot commentators are not commenting live, they know what happened and they just keep talking about the people that they know are going to win. And they usually put in a human interest story about the athlete that is about to win. So why watch the race?

Here is a piece of advice to nbc execs -- the main reason I watch sports at all is because sports are NOT predictable.

So yes, in general it is not surprising at all that these are the same TV execs that thought up the entire Leno Connan fiasco.
