This is a brief list of technical obstacles that I've had to overcome with various hardware and software packages.

• Printing from MacOS 10.4.x to a CUPS Server v1.2.x
• Fix for compiling X.org Server with --enable-debug

Here is a place where I post some of my more creative and useful UNIX one-liners.

ls -1 ${dirname}|> | sed 's/\-[0-9.]\+tar.*$//'

This will only work if your filenames fit the following format: ${MODULENAME}-${VERSION}.tar${SUFFIX}. Furthermore, the version must be dot-delimited and the ${SUFFIX} can be any length (or empty). Luckily, this is the most common package naming format in use for open source software distributions.

awk '/-/ { print "\x22" $1 "\x22;"; }; /^[^\-]+$/ { print $1 ";" ; };'

I like GraphViz. Since Graphviz uses a number of common characters for it's formatting language, you cannot use these as bareword names in your graphviz code. You must enclose the offending names in quotation marks. The above code will process the long list of words that you wish to ”graphvizify” and make them parseable by the graphviz software (such as dot).
