I didn't get as much done as I wanted tonight, but my inbox is a little smaller, and I got a lot of the initial work done to the suggestion area.

Dormando's going to run the suggestion area.... I'd have given him FTP access to it already, but the FTP daemon isn't setup to notify another process to transfer the stuff to the other servers. Maybe NFS would be a good idea. On the other hand, I kinda like having the servers separated with different passwords, no trust between them, and separate copies of the files.... but maybe it's not worth it. I'm not sure. Thoughts? I was just going to have the FTP server make note in the database what files have been changed, and the other machines can poll that every minute and rsync what's changed... but then I'd need to add some trust between the servers, so what's the point of not using NFS? Hmm.

Other things....

Somebody needs to take over the text messaging stuff, because I don't have time to maintain it. Whitaker?

ASL thinks the memory is bad on lj-stan, so I'm going to go in tomorrow and run a memory test program they recommended on it. Hopefully it is bad and they ship us some more memory or something.... I want to get that machine up soon.

My friend said he wrote a patch awhile back for mod_backhand that fixed the multiple cookie bug, but couldn't release it due to his IP agreement. Now that he's out, though, he was free to reimplement it and release it, but he couldn't remember what he did or something. So no progress there. He may still figure it out, but I'm not hopeful.

Directory is still down, because the directory code indirectly crashes MySQL, because MySQL's table handler crashes when a table gets too large or too small too quickly. I can't make a repeatable test case, though. I suppose I could turn it back on, but then the site is god-awful slow while MySQL restarts after a crash, and if it restarts during a high traffic part of the day, then we're fucked for quite some time because all of MySQL's cache is invalidated, queries take forever, queries pile up, and then everybody starts hitting "reload" to make things load, piling up more slow queries for the already backlogged server to deal with.

Bad hardware, buggy mod_backhand, buggy database.... see a pattern here? This isn't fun. These aren't my damn problems, but I have to deal with them. Grrrrrrrrrrr.

I'm going to bed. Maybe I'll care more after I get some sleep.
