I'm not sure that mach and pH are units per say. pH for example is on a nonlinear scale and mach itself is unitless. Maybe that's totally irrelevant. I guess its fruitless to try and apply logic to language and better to just acce

So much good science going on here. Original experimental setup to turn a stochastic process into a repeatable one. Proper application of computational methods to study experimental results. Albeit I think I can see some problems with the A

It really makes no sense, every other unit follows the number but with money it goes before. The temperature outside is F10, that package weights lbs14, the football is at psi1.8.

Updating the seed is extra pointless operations but if your PRNG is 'good' it shouldn't cause major numerical problems. Besides the author is only sampling the PRNG 1 million times, this is hardly enough to stumble upon any p

We've known about silicene and germanene for a while, the question of their stability free standing is still open. But because their application primarily lay in electronics the goal is to grow a silicene or germanene in place, on top

The last author too, excellent! What kind of IO bandwidth can you currently get from DNA? Does reading from it damage the DNA? What kind of hurdles need to be overcome to bring this to market and are they hurdles we can overcome in the near

Haha that paper was published today! Are you the author? This is pretty interesting. I'd love to read the paper but it looks like I can't download the article yet since its not finished uploading to the site.

Doesn't DNA have a halflife of like 13 years or something? Wonder what the error rate is on 700TB of DNA just sitting there for a year. I guess you could engineer a system with multiple redundancies and checksums, with that kind of den

"miles ahead of Windows for research" For example, only 2 of the currently fastest 500 super computers run Windows and 1 of them is owned by Microsoft. All of the others run Linux or Unix. "Since when are 25-year-old command-

I use linux for research for several reasons. The most important reason is that I own several high performance computing resources that need to run code with as little interference from the OS as possible. Furthermore I need these machines

Yes, I do exactly the same thing! The first 20 problems in particular are excellent for learning a new language. It covers basic math, list operations, file IO, string parsing; in other words all the basics in learning a new language. Plus

We can talk about music, politics (civilly), travel, technology, relationships, family, friends, books, TV... but since we can't talk about sports that is somehow a problem? If you're interested in sports go for it, if you're

Great question! Since they're emanated in jets, the GRBs travel in a conical shape that spreads out as it travels. Check out page 19 of this paper, it has a histogram of the jet opening angle; http://arxiv.org/pdf&#x2F
104.
by acadien 12y ago
It's just statistics. You look at how often we see GRBs, how long they last (on average), how intense they are (on average) then do a big time integral and figure out the odds of a big one hitting earth over such and such a period of t

I wonder if this is meant to replace the ARES project which seems to have gone nowhere. http://marsairplane.larc.nasa.gov/ I'm not familiar with the details of either project or why a drone might be advantageous over a

You could probably just drop moves that are below a certain threshold after every k games.

Yes, its because no other piece can take a king but a king can take all other pieces. The case for taking a king is actually quite rare!

Hm maybe it depends on your income level? I have friends in Shanghai that live on a fraction of what I live on in the US, we're in comparable income levels but no where near wealthy.

by acadien 12y ago
Anyone else shocked that China only has 1.6m relative to the world? Maybe this is because it doesn't take into account relative cost of living and cost of goods. I imagine a million USD goes a lot further in Shanghai than in SF.

Because check mate is a very small subset of possible moves at the end game, I'm guessing the vast majority of games will end(?) with 2 kings moving around randomly for all of time. This assumes most games will make it past the hump of

Do you have a repo with your source or an example? In my experience conjugate gradient, powell's method or any other linear optimization is essentially useless with >100 variables or so. Optimizing anything with thousands of variabl

by acadien 12y ago
It depends on the problem you're working on and the number of variables you need to optimize. If you only have <20 variables on a nice smooth surface then yeah a shotgun approach is probably going to work, then again pretty much an

I'm trapped using 2.7! On this machine it looks like I'm running 2.7.8. Files are roughly 1GB each. They're on a relatively slow file system, just a single HD on this machine... no raid, no ssd.

When you do your timing tests make sure to do it on different files to make sure you aren't taking advantage of caching your system may be doing. That may explain some of your timing discrepancies. And when I say blazingly fast I me

by acadien 12y ago
I've done timing tests and it is typically on par with tail & wc. The bulk of the time is wasted reading your file into ram, the time it takes to count the lines is essentially 0. Edit: Of course I misspoke, yes tail is much faste

by acadien 12y ago
Yes another super useful trick you can use with this scope trick is to get the length of a file (or its last line) just do: for i,v in enumerate(open(f)): pass now 'i' is the number of lines in your file and 'v' is t

It feels like they're just reclassifying heuristics as AI and then saying AI is everywhere. Also there is not a single solid example of what the author refers to as soft-AI. The author says things like "... developing highly compl
