building git on sunfire

wgetthe latest git tarball -

potential git-diff speed up by skipping is-binary check
While working on gsoc 2011, I identified the is-binary check as a potential slowdown in my personal notes. (Yes, it's done for every file.) I tried to disable it with a command-line switch to git-diff, but that was ugly and hack-ish.
Recently I was looking at diff codepath again ...

symmetry, non-negative distributions
I was researching
buffer_is_binary()in git the other day in the hopes of speeding up the diff codepath, and stumbled on to this thread that digressed into statistics, a module I'm taking right now. Interesting read. -

potential dangers of building python extensions in mingw
Recently, I ran into some difficultly getting lxml to compile and work. It was crashing mysteriously on the seemingly-innocuous
fread(). After many days of debugging, I stumbled upon the cause:Each copy of the CRT library has a separate and distinct state. As such, CRT objects such as file handles ...

thoughts on Bitbucket's launch of support for Git
D-Day: Tuesday, October 4th, +0800. I remember sleepily reading Bitbucket's announcement email; for added effect, my friend excitedly alerted me to the announcement too.
I saw it as a major, game-changing move, but I found it strange that most of my feeds were quiet on this, save for this ...

dumping all files in a git repo
Had to do a code submission for a module of mine.
Actually, we're supposed to use hg. I'll talk about my hack-y git->hg workflow (instead of through hg-git) when I get the time.

transferring binary data with base64 and paste bins
Nowadays we're pampered with many data transfer methods - from the physical (flash drives), to the "cloud" (Dropbox).

subtree merge
I was compiling my gsoc code submission the other day. It was done as a git repo (available here), mostly collections of patches, but I also had some gists lying around. Their individual revisions were probably not that interesting, but just adding them as history-less blobs would was also undesirable ...
