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 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: 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…

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: 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)


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? –  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:

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:

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
