I recently came across a couple of tools that may be helpful to someone and I have created a repository for some of my stuff:
Maatkit has a lot of cool utilities that allow you greater control of MySQL. I recently found it very useful for restoring an extremely large MySQL dump by using the mk-parallel-restore. For information about its feature, either visit the website or you can check out this Linux Magazine article.
HTMLDOC allows you create PDF documents of html pages. You can convert pages one page at a time, or as a book. So you could use wget to download the pages of a website recursively, including the graphics and then pdf'ify it into one book with references... pretty useful.
Some of my stuff
Since I'm not sure how much longer I will have my academic website, I am starting to move some of the code that's been hosted there to another location. I have also added a few things that are not listed on the old code page or elsewhere on my academic site, such as a DC3 Image Assember script that worked with the last DC3 challenge (haven't looked at the current one) and a Virus Total hash checker that takes a list of hashes and posts them to Virus Total to build an html report. This last one needs some modification however, since if one is checking lots of files Virus Total starts to report errors... Hopefully I'll have some time to create a new version in the future...
