The original GeoCities website has been destroyed: http://www.geocities.com/hirak_99/goodies/finddups.html So here is a copy of the zip file: finddups There are a number of alternatives in this question and on alternative.to, but I'm not sure if they meet my needs yet.  Since this still ... http://www.endolith.com/wordpress/2010/01/15/find-duplicates/ Some signal-analysis-related Python scripts: Several different methods of estimating the frequency of a waveform Peak detection for spectra Measure total harmonic distortion plus noise of a sine wave (THD+N) Apply an A-weighting filter to audio files I'm sort of intending to combine them all into one eventually. http://www.endolith.com/wordpress/2009/12/13/audio-analysis-in-python/ Signal generator 1.0.2 Outputs sine, pink noise, and white noise Volume and frequency sliders Controls are hard to grab at the edges Volume control is independent from the phone's volume control Doesn't go below 100 Hz Sine waves are distorted and badly aliased at high frequencies.  THD+N measurements: 100 Hz 0.149% 1 kHz: 0.08% 10 kHz: 7.1% 20 kHz: 20.15% Spectrum ... http://www.endolith.com/wordpress/2009/11/24/android-audio-applications/ Wikipedia describes independent component analysis as "a computational method for separating a multivariate signal into additive subcomponents supposing the mutual statistical independence of the non-Gaussian source signals". (Clearly, this was written as part of their campaign to make technical articles accessible.) In normal people words, ICA is a form of ... http://www.endolith.com/wordpress/2009/11/22/a-simple-fastica-example/ In wide views, it should show whole-Earth (or whole-Mars, etc) images like the Blue Marble instead of a patchwork of smaller images. There should be a "fovea" at the poles to avoid the problem of hundreds of converging strips when zoomed into the poles.  This happens for both the planets and ... http://www.endolith.com/wordpress/2009/10/31/two-improvements-to-google-earth/ Here's the same Ubuntu Forums experience polls charts as in Ubuntu release quality, but I'll keep this one up-to-date with each release: These charts lump together upgrades and clean installs, since the ratios are similar for both, and it shows more clearly the overall trend. Feisty (1,387) 47% 23% 30% Gutsy (5,479) 22% 44% 34% Hardy (4,296) 23% 46% 31% Intrepid (1,962) 21% 35% 44% Jaunty (2,025) 30% 37% 33% Karmic (4.063) 31% 33% 36% The ... http://www.endolith.com/wordpress/2009/06/24/ubuntu-isnt-getting-any-better/ Similar to the Intrepid fresh install notes, I kept notes while installing Jaunty from the CD on my Dell Inspiron 8600, trying to see it the way a complete newcomer would. Again, the language selection screen is ugly. Again, you have to reboot after checking the CD for errors. Currently it says "Press ... http://www.endolith.com/wordpress/2009/06/22/jaunty-fresh-install-notes/ I recently got a new hard drive, and installed Ubuntu on it from scratch.  I decided to put myself in the mindset of a newcomer and see how the experience compares now that I've been using it for two years. My unorganized notes: Language selection screen after booting from CD ... http://www.endolith.com/wordpress/2009/02/17/ubuntu-newcomer-experience/ This is a test post to see if I can publish Ubiquity commands with WordPress. Here are some real Ubiquity commands I used the More tag so that the link rel tag only triggers Ubiquity when you view the post itself, not when viewing an aggregate of several posts. Or would ... http://www.endolith.com/wordpress/2009/01/19/some-ubiquity-commands/ When I first installed Ubuntu in 2006, all my hardware worked out of the box.  It needed a few tweaks to run correctly, but it was much easier to get running than other distros I had tried.  I was very pleasantly surprised, and Linux became my primary desktop for the ... http://www.endolith.com/wordpress/2008/11/19/ubuntu-release-quality/
