Last month, my work got a new H.323 video conferencing unit, and today we had our first real test: a lecture given at SFU that was streamed to us. For the most part, it went really well; there were no big screw-ups and everything went as planned. During the second half of the conference, though, the audio was intermittently choppy. I'm not certain, but I think that a local user's Internet radio stream may have caused the problems.
If that's the case and it would surprise me, since I'd assumed we had a pretty damned fast connection to the Internet then I'll need to start adding traffic shaping to our firewall. Working on the firewall is something I've been putting off for a while, since it's a bit obscurelovely pf firewall, littered through with quick rules. But there's a good tool for pf unit testing I've been meaning to try out since I heard about it at LISA. Probably won't be as big a help with the traffic shaping stuff, but at least I'll be reasonably sure I'm not screwing anything else up.
And now I'm wondering just how hard it would be to come up with (handwave) something that would combine automatic form generation, web-based testing code and summary code. We have these multiple conferences that need registration pages; while some of the information is the same (name, email address) some is different (one conference has a banquet, another wants to know if you're going to be attending all three days). Putting all this in a database and using something like Formitable to generate the form seems perfect.
Since I'm already using Perl's WWW::Mechanize and Test::More to test the pages, it'd be nice to have it look at the stuff used to generate the form and use that to test the page. (That's not the clearest way I could put that, but if I don't write this down now I'll never write it down.) And if I could add something that'd automatically generate summary pages for conference organizers, it'd be even better; stuff like email and address is always easy, but being aware of special questions would be nice too. (Though maybe not necessaryhow hard is it to generate summary pages?)
Trouble is, this is a lot of deep thinking that I've never really had to do before. I suspect this sort of thing is a good programmer's bread and butter, but I've never been a programmer (good or otherwise). The more I think about this, the more I can't decide whether this is really hard, possible but too much effort to be worth it, or already done by something I haven't come across yet.
The little things I can handle, though.
looks like it's happening because of a mixup between rand(3) and
random(3). In Linux, both have a maximum of RAND_MAX, but in
Solaris the latter has a maximum of 2^31. This wreaks havoc with the
let's-shuffle-the-playlist routine in XMMS, and we end up with a
crash. Once I figure out how to program in C, it shouldn't be too
hard to get it fixed.
