Trac and googlebot, a crafty trick!
I noticed that google was going crazy indexing trac for doctrine. Today it downloaded over 90000 pages, transfering 3 gig of data! It was causing quite a bit of load on the server (not huge amounts, but enough to show in my graphs!)
Eventaully , I came up with a nice little trick for reducing the number of hits google will make against a trac install. Google have extended robots.txt to allow some slightly improved pattern matching. Here's my snippet, if you don't understand it, please don't use it.
User-Agent: Googlebot Disallow: /*?rev*
resizing a ext3 disk image
Took me a while to figure this out, so thought I'd put it here for others. This is useful for Xen setups, where you use a file for the disk image. AFAIK, you can only grow an image, not shrink it.
# dd if=/dev/zero bs=1M count=1024 >> disk.img # e2fsck -f disk.img # resize2fs disk.img # e2fsck -f disk.img
This makes the disk image bigger, checks the image, resizes the file system, and then checks it again
Finally, Namespaces in PHP?
Check out this blog post. Looks promising, PHP might finally get name spaces, and somehow, they have managed to use the '::' separator! Great news, but I'm not going to believe it till I see it released, even though it's been checked into SVN already
