YAPC and alert on Win32

Another whoo-hoo! YAPC::Europe was great! Fantastic lectures, great folks, and Octoberfest was a madhouse. My paper and lecture notes are online here.

I've been driven mad - well, more like peeved - by the lack of the alarm() function in Win32, so I ripped off some code and built this to do something similar.

Finally wrote everything about our hashing system

Woo hoo! Got one monkey off my back, finally.

I wrote a 12 page paper about how our distributed hash harvester actually works. It's not on the web yet, because it needs to go through a review process, but I hope it will be soon.

It's not the most spectacular use of Perl. Having the same piece of code running on 6 PCs doing loosely parallel hashing, monitored by a master cron job and a couple database tables isn't rocket science - rockets are someone else's job.

Using sexeger was the best improvement we've made so far. It halved the time we were spending in our slowest section of code, and lowered our overall run time by 1/3.

I plan on going to YAPC::Europe::2002 and I submitted an abstract; hopefully I can give a presentation, but if not I'll certainly want to pick up as much input as possible. There's so much more I should be doing with benchmarking, hashing and ODBC modules.

More later, and hopefully a URL for the paper in the NSRL website.

hacked DosGlob.pm for space in filename

[ #4300 ]
I noticed that when I used
@List = <$config{'root'}>
to get a list of filenames from a root directory, then acted on that list, filenames with spaces were handled badly.

So I hacked /lib/File/DosGlob.pm around line 155 to be:
@pat = Text::ParseWords::parse_line('\t+',0,$pat);
instead of s+ . And it seems to work well.

I gotta add some stuff

[ #254 ]

Sometime soon I'll genericize that file upload script and put it in here...
