sox in Ubuntu

When installing sox, make sure to also install libsox-fmt-all which has the alsa/oss drivers to read from /dev/dsp and has the nice codecs like ogg.

Firefox Crashing

The current version of firefox is always crashing. I'm back to Opera to see if it's more stable.

Hardware Hacker

The Washington Post published a piece on clubs which allow people to play with electronic hardware. While they profiled HacDC in the greater Washington, DC area, a worldwide list of places can be found at http://hackerspaces.org.

I'm working on my own LED light bulb which would fit into a candelabra base and direct light all over without the opaque white ballast base present on compact fluorescents.

I've done some basic electronics work with my ham radio antennas which I whipped together before my sidekick antenna came.

Padlock Random Number Generator and PMM vs PHE and AES

They aren't that much faster. The random number generator is about 30% faster than reading from /dev/urandom. With the montgomery multiplier less than a 2x speed up, most of padlock seems to be not as impressive as the AES speed up.

SHA1 is the 10x speed. SHA256 is about 20x faster than openssl. So along with AES, these parts definately help.
