Ubiquiti devices all the way [1] [2]. They're the hacker's choice! Before I discovered Ubiquiti, the Linksys WRT54Gx series was my goto. The problem with them is that, as a given WRT54Gx line matures, they usually shave down the s

But Flanker's full-message parser is still 8x faster than email.parser's full-message parser, according to their benchmark. It's pretty unlikely that many well-used and years old OSS language libraries have orders of magnitu

This is great guys. It's surprising that you're able to get an 8x-20x speedup over email.parser with another pure python parser. (What does this say about email.parser, eh?) Did you consider using a C extension and tools like lex

ImageMagick can do this too: convert -filter Sinc -resize 200% input.png output.png However, as pointed out by other commenters, sinc by itself isn't the greatest support function for enlargement due to the ringing artifacts [0]

Another way to derive a closed form for the Fibonacci sequence: put the recurrence relation in vector form and solve by finding the eigenvalues. (Which, beautifully, turn out to be the golden ratio and its rational conjugate.) http:/&

Totally agree, although the author's use of vlc definitely qualifies as a clever hack. I want more hackers to realize how insanely easy it is to programmatically generate video with ffmpeg. Just write a program that dumps raw RGB frame

Has anyone else noticed that Gogo shows higher prices to mobile phones? That seriously pisses me off. The fact that none of my mobile browsers can change the user agent string pisses me off even more.
