Here's a little experiment that I did last night after Kyle's Git talk—I put this blog under Git control.

I have been maintaining the content of this blog in Subversion since March 2005, 1292 days ago (and in CVS before that). When I moved this blog from my Fedora Core 6 box to my Debian box 64 days ago, I don't have enough disk space on the partition to hold the 1.9G Subversion workspace. So I simply used the 916M export from Subversion.

One of the questions I asked yesterday was the disk space usage of Git. And Kyle assured me that its much less than Subversion. So I gave Git a try:

[weiqi@gao] # feta install git-core
Blah Blah Blah
[weiqi@gao] # df -h /var
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/gao--2006-var
                      2.9G  2.0G  732M  74% /var
[weiqi@gao] # git --version
git version 1.4.4.4
[weiqi@gao] # git init-db
defaulting to local storage area
[weiqi@gao] # echo *.bak > .gitignore
[weiqi@gao] # git add .
Blah Blah Blah
Blah Blah Blah
...
[weiqi@gao] # df -h /var
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/gao--2006-var
                      2.9G  2.2G  550M  80% /var
[weiqi@gao] # git commit
Committing initial tree 9c31562f7a84c42ebab872d245a49b637b1e0395
[weiqi@gao] # df -h /var
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/gao--2006-var
                      2.9G  2.2G  546M  81% /var
[weiqi@gao] # du -sh .git
187M    .git

So everything fits in there nicely. What would have been a 1.9G Subversion working directory now fits into a 1.2G space. (This is a bit of an unfair comparison because I did not convert my Subversion repository to Git, so I don't have much history in Git, yet.) And yes, Git is blazingly fast.

I'll just have to push it to another box from time to time.

And here's how the repo looks in gitk, a Tk GUI that Kyle demoed yesterday:
