I took the month off work and traveled around Japan, Chile, and Argentina.

During my travels, I managed to do quite a bit of work on The Silver Searcher: https://github.com/ggreer/the_silver_searcher . It's a clone of ack[1], but written in C instead of Perl. I've done a decent amount of profiling[2] to find slow parts and improve the speed. For literal searches it uses a version of Boyer-Moore-Horspool strstr[3]. For regex searches it uses the new JIT compiler in PCRE[4].

Depending on the search, it can be 3-5x faster than ack. And thanks to some contributors this past month, it's now in homebrew and Gentoo portage.

Well, back to the grind tomorrow.

Add ability to replace and I'm your fan. :) Until then I'm using my own http://github.com/piranha/goreplace (built in March a year ago :)).
