Doxygen Graphviz DOT problem in Ubuntu 10.4 Lucid
The graphviz version graphviz 2.20.2-8 from Ubuntu’s repository seems to have some bug in DOT that causes it to hang.
The latest from http://www.graphviz.org/Download_linux_ubuntu.php is 2.26.3. However there’s maybe a funny in the dependencies as I needed the base and the lib packages graphviz_2.26.3-1_i386.deb & libgraphviz4_2.26.3-1_i386.deb as otherwise tryign to run DOT without the lib package you get:
dot: error while loading shared libraries: libgvc.so.5: cannot open shared object file: No such file or directory
Makefile debugging article
Makefiles are pure evil. The concept was nice but working with them is awful. I have wasted more hours/days/weeks chasing down makefile problems because the #@$#*$ idjiots that came up with the idea must have assumed nobody would use more than one makefile and build nothing more complicated than ‘hello world’. I put this right up their with Microsoft’s Windows Registry as one of the top 10 dumbest implementations of a good idea ever.
Now I feel better…

Debugging Makefiles By John Graham Cumming, February 05, 2007
Educational materials site
Good place to look for a range of primary/secondary lessons (not just science):
From which I found a link to here:
http://phet.colorado.edu/ which has various simulation programs available (java mostly)
Video Tools list
Things for analyzing/processing video files (excludes editing unless it happens to do that too)
Players
VLC – everything player/streamer
SMPlayer – player, IMHO better than VLC if it’s just playback needed (which is weird since they’re both based on ffmpeg, etc)
MPEG tools
(mostly free ones, get Elecard StreamEye for any real work).
Tsviatko Jongov’s tools page (multiple useful utilities that he developed)
Mediainfo Just like the name says, Media info…
tsMuxeR (was tsMuxRGUI) – split combine media
StaxRip – another muxer/converter
AVIDemux – more of an editor but can do a lot of useful conversions too
meGUI – an encoder front end
MKVToolNix – Matroska tools
Cypheros – assortment of TS related tools – purchased TSDoctor (was cheap) to have some sort of error checker, but it doesn’t do much in terms of displaying ‘decoded’ h264 fields, etc.
VirtualDub no explanation needed?
w6rz.net – test clips raw and mpeg2
Stuff looked at but really don’t use
TSReaderLite – freebie version to look at mpeg2 TS (need full version to be useful for h264)
MPEG TS Stream analyzer – shareware – have not tried it
Maybe someday this will be something: http://code.google.com/p/ts-mpeg2-analyzer/
Not quite software
Nice DSP/FFT interactive site
Aimed at the basics, but what a huge improvement over illustrations in a text book.
Gullibility and the audio biz…
I’m always forgetting links to the true weirdos of the audio biz, luckily someone else maintains a great list:
http://www.ilikejam.org/blog/audio/audiophile.html
And an excellent collection of “no BS” commentary on speaker wires but also illustrates how the audio industry has fallen into a death spiral of promoting woo-woo instead of actual value. And then we’re all shocked that people think MP3 at 64 kbits/sec sounds good…

Another analysis – wish there was a bit more info on the ABX tests

Yet another good set of links to materials on the silliness that pervades the consumer (high-end) audio business:
online EE book
Looks like a lot of effort is going in to these to create a comprehesive book http://www.ibiblio.org/kuphaldt/electricCircuits/index.htm
Good page for old (mostly) tube audio
lots of old books too. http://www.pmillett.com/index.html
Series excerpt Bob Pease (edited) book an analog
More stuff for my reading list
