Apparently, the Cray T90 in the 32-processor configuration had 360GBps of shared memory bandwidth - this is still many times above a shared memory configuration that you can get on the desktop today. Of course, supercomputers have largely

How exactly was the USSR "imaginary"? And how was it invented by "govt"? Do you mean the US government? Please try to formulate your thoughts more clearly, and please study history more carefully before proposing sweeping theories.

This was a piece of reporting that simply never took off. The reporter was not able to get the subject of the story to open up, and the whole article contains nothing that was not found in the endless discussions on the forum that he refere

It's not my favorite magazine, but I've read long New Yorker human interest pieces, and they've always had more, well, interest than this. The problem is that when you see a long piece in a respected magazine on a subject that you are int

I am a runner also (finished one marathon with a time that is nothing to write home about), and was looking forward to an interesting story. I read this whole article with a growing feeling of incredulity, not about the cheating that it des

Your information is completely ridiculous, and doesn't become less so because it has appeared in some books. It has been debunked not by some random guy on the internet, but by the Albert Einstein Archives at Hebrew University, to which he

Yes, you are wrong. Einstein did very well in elementary school, and was accepted to a competitive gymnasium at age 9. He also did very well at the gymnasium, although he didn't like the rigid structure. He left school at 15 and applied to

Please don't spread legends. Einstein excelled in school, and his grades were fine (his only weak subject was French, which he apparently had little interest in). See http://www.albert-einstein.org/article_handicap.html .

I think that the reluctance to pay for anything online is what explains prices like $0.99 - the developers are trying to pitch their apps as "almost free" or "just about free" - sneaking in under that impedance. The whole point of that pric

I am not sure what you mean by compressed sensing - if you're only interested information such as "child-sized object moving rapidly across field of view", then you can get away with smaller sensors, but here, CS is also talking about faces

A couple of notes about the limits of things that have already been reached today: A pixel in a camera sensor has to be a couple of wavelengths in size. This is basically the size that we can make them now. There are also diffraction limits

I really recommend reading the thread at http://coris.noaa.gov/exchanges/coralfuture/coral_future.pdf - this is a discussion by working scientists, and although it's from 2001, the predictions of the demise of coral reefs were already ver

Don't know where to start. First, you are seriously naive or uninformed if you think that Putin is not corrupt on a gigantic, unheard-of scale. Take a look at the so-called Putin's palace on the Black Sea, http://www.youtube.com/watch?v=Ac

Yeah, absolutely. Revolutions have worked out so well before, especially in Russia. What Russia needs right now is some serious destruction and civil war, followed by a few decades of rule by hard men who know that their Cause comes before

I think all this does is illustrate how ridiculous US export controls are, and how hypocritical the West's stance vis-a-vis China is. First, the idiocy of the export controls: maybe they made some sense when the US was a sole source for cer

The town itself doesn't seem like much of a bribe, since the funding was provided as a loan to Angola, and is being repaid from oil revenues. Also, the vast majority of the workers were Chinese, although it's pretty usual in such cases to n

Wow, that seems like a pretty random response to the BBC saying a town right next to the capital is "perched on an isolated spot 18 miles away from the capital". And by the way, what you said is not true. Please investigate the concept of s

This link has some interesting satellite photos, and some discussion in Portuguese. http://negociosangola.blogspot.com/2011/04/nova-cidade-do-ki... I wonder why they picked such an isolated spot 30 km from the capital. Angola has one of t

They sure are disconnected; you've made clouds of dots instead of continuous shapes. Ponder the fact that a dumbbell shape is easier for a human to process and recognize than two disconnected dots. On the other hand, if you're on some kind

Now you're aiming for the laurels of hieroglyphic writing, which has kind of lost almost every battle it fought with alphabets and syllabaries for the last couple of thousand years. It's not even convincing that this will be a good hierogly

Please explain the advantages of this over reading Braille dots (which lots of sighted people can do already), and please explain the lack of reports by sighted people saying "hey, I noticed that reading in Braille is faster and easier than

by yaakov34 15y ago
That makes about no sense (except as really deadpan satire), the strength of the human visual system is in "chunking" shapes, and making letters into clouds of disconnected dots is about the last thing you want to do to it, if you don't hav

I agree that it's perfectly legitimate to discuss the runtime needed for Dart, and point out that it's a disadvantage that it is needed at all, or to criticize the runtime, or whatever. What shocks me is that people who are supposed to be t

by yaakov34 15y ago
This is called "a runtime". A bunch of things that have to be loaded on the target machine for use by a compiled program. Just about every compiler works this way, whether the output is machine code or JavaScript. It is possible to not emit

I quite honestly had to read this over a couple of times to make sure this is not some kind of a parody. I don't understand why people are complimenting this. Let me count the ways: 1) Asking a client to produce a quantitative "job spec" li

I am not suggesting a bag of tokens. I think I would like some segmentation (e.g. a banking token that I wouldn't necessarily carry with me everywhere). But that's a personal preference - the more tokens, the more security and reliability.
207.
by yaakov34 15y ago
The token would either have to work with a single-sign-on authority that would authenticate you to other parties (like OpenID, but hopefully easier to use), or it would contain multiple "authentication slots" for the parties that issue cred

I don't disagree with that, but I am making a different point. Password systems, by their nature, require lots and lots of actions from users: making up passwords, resetting them when expired, making a keyfile and keeping it safe and backed

Not precisely. Sure, with a session open on your computer and the token inserted, anyone controlling the computer controls the session. But once you close the laptop or take out the key, the access is gone (this is how it works with the mos

And if their laptop (or smartphone - there are even worse security breaches possible with them) is rooted and keylogged, then both of these things will happen simultaneously. And they won't find out right away, either. EDIT: the other probl
