Command-line

• tsvutils for tab-separated file manipulation. Includes converters to/from xlsx, csv, mysql.

• Other commandline utilties: pskill logtime

R, the love-it-and-hate-it statistical and visualization programming environment

• util.R which tries to solve a few of R's annoyances
• example for embedding C++ in R
• .Rprofile
• My favorite two R websites are Quick-R and RSeek.
• My new favorite R packages are Hadley Wickham's ggplot2 and plyr.

• util.py contains utility functions for python
• counter.py does iterator monitoring like pv
• sane_re.py has some tweaks to python's regex API
• ansi.py helps print colorized text to the console
• lsv.py lists variables in interactive python. reddit discussion
• autolog.py is a set of decorators that log function calls in a colorized outline format.
• cgiutil.py containing, among other things, an options parser in the declarative, type-inferenced style of trollop.
• analogous wsgi querystring options parser.
• .pythonrc

Ruby

• mycgi.rb, an extension to ruby's cgi library
• .irbrc

Scala

• Scala Syntax Cheat Sheet

Matlab
