Here are other miscellaneous things I've done that don't fit into other categories...
I oc'd a Haswell from 3.4 to 4.4 Ghz, a 30% speed increase. I also cut through some unclear thinking on Overclock.net to write a sensible man's guide to overclocking.
I've mostly done small edits on Wikipedia, but a few are notable.
Notes to myself about how to work certain MediaWiki things. If it helps someone else, that's fine. Donate money to me if you like.
