Chatham MA beach panorama – using Hugin

Cape Cod beach panorama

Cape Cod beach panorama

only my second attempt at using Hugin. Done holding the camera so didn’t get enough overlap. Horizon didn’t come out straight.  Also learned that moving people and waves are going to throw it off (yeah, obvious…)

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

intro article

but it makes it painful to figure out why something doesn’t start as there’s no way I’ve found to debug – i.e. it run the start/stop, etc in their own process and messages seem to get sent to /dev/null…an echo “hello” 1>&2 doesn’t end up in the logs.   Someday I’ll understand why…

Linux GPL terminal program with logging and other features

So far this seems like the best terminal program for Linux:

(there’s a couple of things that show up in google for Terminator)

Though for Windows I still like Secure  CRT:
