Gather Bryan's been reconfiguring the demo instance to run against the larger CMTS (now scanning 2500 modems), so I don't know if there was any change in processing load between the limited and unlimited queries. Going to leave the changes in-place because it seems very likely that they will have a positive effect and no ...

Well, the memory leak (whatever it is) is down to about 50MB/day. That's still not going to work in a production environment, but it's slow enough that the demo can run for about 11 days (well, make it 10, it needs some ram available for actually interacting with users). It's also slow enough that the ...

I haven't had a chance to test this theory yet, but it makes so much sense...

When doing get bulk requests (which are done once for each modem on all non-intensive scans in Cinemon), the default behaviour for an agent is to encode 255 records for each requested field. That is, if you are requesting ...

Been working in Windows all day (good old reliable Windows ;) ). I'd forgotten how much more worn-in my working environment is here, everything set up for two-key access, everything defaulting to opening in the right directory, every tool winnowed from the pack over years of Darwinian selection, every device "just working", without few if ...

Did rather a lot of cleanup of the code today. Finished a number of "polish" elements (e.g. links upward in the hierarchy, retaining hierarchy names and comments through upload/download cycles, that kind of thing). Confirmed that email alerts do work when the email account is set up.

Last task of the day was sitting down ...

Even updated the viewer to allow for picture-in-picture (though I don't have cable-tv-cables or audio-cables to make that work yet). Linux may be stable and fast, but Windows still has it beat on driver support.

Anyway, back to work; going to be a long day I'm guessing. There's no food in the house (didn't get ...

Well, I spent about 1.5 hours working on getting the new TV card working (about 1/2 hour longer than I'd intended). Unfortunately, to do that I needed to recompile my kernel (gods what a stupid system that is, honestly), and something wound up upsetting the magic that let the tablet work. Have spent almost 4 ...

Found a small leak. Basically I keep a table to all streets with (num,apt) indexing lists of modems at that location (normally only a single modem). The code to do that, however, was assuming that it was starting from scratch (i.e. at system load time), whereas these days the locations are re-loaded every 20 minutes ...

You'll need an SVG browser for this one, but I figure it's about time everyone had one anyway :) .

Bleep. There was a dip at 6 hours, but after 20 minutes or so it started climbing again, so we have an unusable product (demo is still fine, it's been running for 17 hours now).

Worse, though, there was a group that went offline, but I got no email. Of course, I forgot to give ...
