I just tried it. On first start up (when the 13MB pypy executable has to be loaded into memory), it's slightly slower. About 0.5 to 1.0 seconds, I'd guess. My highly scientific benchmarks (time python -c "pass") give no noticeable differenc

the JIT compiler is itself automatically generated Indeed it is. Compiling took 9000s on a 2GHz Dual Core Athlon with 2GB RAM. Don't even try to compile it on a machine with 1GB RAM, your system will start trashing heavily and finish some

Disclaimer: I'm from the EU and I'm only going to finish my studies in Switzerland. Everything I say is only a guess. To my best knowledge, you need about 14.000€ for a year as a student, but this seems to depend on your location. But sin

Thanks, OpenSSL actually uses 0x10001 by default for e . I'll use it instead of GPG from now on to generate keys.

Thanks for answering my curious questions so far. =) Since I messed up formatting earlier, my first question about generating keys with this particular exponent was hidden: Do you know how to generate such a key pair using gpg (or another t

DO: Use a 2048-bit RSA key, a public exponent of 65537, SHA256, and MGF1-SHA256. How can I set the public exponent when generating a key? man gpg wasn't helpful. And why this particular number? I can see that it's 2^16+1, but I don't unde

Since I've only the slides, I have a question about the following point: > DON’T: Put FreeBSD-8.0-RELEASE-amd64-disc1.iso and CHECKSUM.SHA256 onto the same FTP server and think that you’ve done something useful. I take it the FTP got co

I've done some first steps in J and it's really mind blowing. It's hard to get into it and you have to learn a lot before you can read programs. (Since I had too little practice, I can't read it.) But the underlying concepts are not too dif

I like Richard P. Gabriel's writing, his words influenced and inspired me. His review is well written and the theme of "computer language evolution stalled after 1980" resonated with me. I have an idea of MOP now, but I'm still too limited

For me, there are three main reasons: * Customizability. It's very easy to build a system just the way I want it. * Rolling release. There are no releases every six months, but when a new version of a software is released, I get it

I spend some time on their page today and another fascinating subject are active essays: http://www.vpri.org/pdf/tr2009002_active_essays.pdf Basically, it's about adding runable and editable code directly into documents, one could say li

I agree. Sometimes, I deliberately set myself the task to be able to explain something when attending a lecture - I make different notes and I believe I understand things better. (pkrumins is probably on the right path.) Interesting enough,

It appears the author used Python while working for the film industry, see for instance the previous post in the blog: http://artificialcode.blogspot.com/2010/04/my-midlife-python...

I was there some 10 years ago and I didn't get quite the same treatment. ;-) It was very interesting to see nonetheless. btw: Should somebody feel like visiting Dresden until August, shoot me a message, I might be able to give you a tour.

I read 15 Bytes from /dev/urandom, use base64 on it and cut of the last two padding characters. That's 2^120 possibilities - just guessing a valid id will require a lot of luck and a collision is very unlikely.

I usually use Google. This will cover blog posts or forum postings, too, which surprisingly often feature announcements of good libraries without any presence on sf.net or similar.

I've been researching data compression the past days, because I wanted to write an article about an interesting algorithm (Compression algorithms are fascinating, unfortunately my studies didn't touch the subject). I don't know if I'll writ

I had to laugh about the comment and then I read your user name. ;-) Good luck, I hope you have a good experience and learn a lot.

Actually they might just use cider ( http://www.transgaming.com/business/cider/ ), which is afaik similar to wine. Half Life 2 and other source engine games seem to run just fine on wine, getting Gold and Platinum ratings ( http://appdb.win

The BeagleBoard ( http://beagleboard.org/ ) may count as desktop. It's a tiny board with a 600 MHz Omap3 with 256MB RAM and the ability to play HD-Video. Power consumption is less than 3 Watt. I own one and it's fun to play with, although t

Yeah, I know this, it's horrible. My problem is with speaking French, Spanish and Italian. Only one of the languages is fine, but once there are two or more, I start mixing words together really badly. I think it's because those languages a

I actually agree, it's very confusing. I'm European and I would write 07.01.2010. On topic: I, too, am Arduino shopping. First I though about getting a Spartan FPGA development board, but I honestly don't think I'll have the time to learn e

Monitors have a much higher resolution these days. When a few years back, 1024x768 on 17″ (75dpi) was the norm, nowadays 1680x1050 on 22″ (90dpi) or 1920x1200 on 24″ (~94dpi) are mainstream. (I'm even at 125dpi with 1280x800 on 12.1″) No wo
