I’ve been eyeing LightTPD for a while now, and figured this would be worth a shot. As it turned out, it only took an hour or so and a bit of monkeying with rewrite rules to get everything built and working.

The hardest part for me was rewriting the rewrite rules appropriately so I could maintain my pretty URL’s.

I thought I’d share in case anyone else is having problems.  I’ve added liberal comments to help understand things better:

Any questions, let me know!

To use:

1. Save to /usr/local/bin/backup_bzr.py
2. chmod u+x /usr/local/bin/backup_bzr.py
3. Edit /etc/rsnapshot.conf and add:
   1. backup_script   /usr/local/bin/backup_bzr.py . [root dir of your bzr dirs]  localhost/bzr

Update: Just realized that maybe this isn’t as useful as I thought.   Seeing as how bzr is self-contained, you could probably just rsync the entire directory and get away with it that way.  D’oh.  So used to old-style VCS that need a separate backup process than ‘cp’. I’ll leave this code here in case anyone else finds it useful.

Follow this link for a working example.

Note that I haven’t tested this on anything except Firefox 3.1 on Linux. Any reports on success/failures on other OS/platforms would be appreciated.

-e-

UPDATE:

Some issues are found on non Firefox/Linux browsers (as to be expected. ).  I’ll post a table here that I’ll update as I fix these issues.  Any one with suggestions, fixes, it would be appreciated.

Over the past few weeks several studios have closed either partially or completely. I’ve been lucky to keep my employment, but a great many friends of mine have not been quite so fortunate.

I’m not sure the best way I can help these fine folks, but the only thing I can think of is to list them here, with links to their LinkedIn profiles. If I missed you, or if you prefer to remain off this list, please let me know.

Recruiters, please help these fine folk.

Updated: Added Justin Reynen, Gavin Wilson, Phil Meilleur, Justin Heyes-Jones, Cameron MacKinnon, Daryl Smith. Remind me if I forgot anyone.

(Feb 1st): Updated: added Mirna Cruz, Mark Lawson and Zeynep. Couldn’t find Jesse Daniel on LinkedIn; someone throw me a link for him and I’ll put it up.

(Feb 2nd): Got Jesse Daniel on the list. Any more?

(Feb 2nd, later that day): Added Ed Tam. Man, it gets more depressing the more I add to this list.

I’m keeping a list of nearby conferences to Vancouver/Seattle here.  Check it out, and leave any comments you have on this post.

Hopefully someone else finds this useful.  If not, it’s useful for me!

In reading up on the subject, I understood probably the best way to go about it is to do a base line full backup, and then a set of differentials. I ended up writing a neat little system in strictly bash and base UNIX tools, and it was actually getting pretty useful until I spotted rsnapshot.

Man, that’s one neat little package, and it’s super simple, easy and straight forward to set up.

In the end, I only had to write one ‘custom’ script, which was to backup my svn repositories, and it was off to the races.

If anyone’s interested in the source to my bash-based engine, let me know. It definitely taught me a lot about bash scripting!

That said, through various Internet caches, I’ve begun to recover my old posts, ordered by the ones it seems people are requesting most.

Let me know if you got here and couldn’t find what you’re looking for!
