A man goes to his doctor and tells him, “I’ve had the song ‘What’s New Pussycat’ stuck in my head for weeks, and it’s driving me crazy.” The doctor says, “Well, I think you may have Tom Jones disease.

Moving to Dreamhost

Thought I’d move from Rimu Hosting to Dreamhost. The VPS we’re on is just too slow and anything that brings the load down is good. I can’t move the secure sites as Dreamhost doesn’t provide any type of SSL, even a self signed cert from the wrong address, without switching to a static IP and handing over $50 US a year.

Comparing integers

Notes for next time: You can check if the unsigned integer ‘a’ is greater than ‘b’ by adding the ones complement of ‘b’ to ‘a’ and testing carry. A twos complement subtraction doesn’t work as a > 0 is always false.

Test after move

All relocated and imported. Now does posting work?

Engines for metaphilter++

Django looks quite decent. Python (not PHP – good), built in basic admin, built in basic user accounts, and the template system is directly applicable to metaphilter. I’ll give it a try using sqlite 3.

Automatic PC fan control

Ratchet & Clank

Woo. All done. Reasonable length, very linear, and a bit…easy. Solution to the big bad: empty 200 blaster rounds for stage 1. Re-stock using the PDA. Empty 200 rounds for stage 2.

Wireless temperature cluster

For measuring the vertical temperature gradient cheaply at different stations across about a heactare of land. A heactare is 10000 m^2 or about 100×100 metres. You could use a set of 1-wire temperature sensors in a local cluster.
