Just to torment me, the Windows install goes flawlessly (Clickety-click, installation trick...)

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 ...

Bleep, that's not what was supposed to happen (What should have been a trivial install of common hardware winds up screwing up core functionality...)

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 ...

Well, that's at least one leak fixed (Now just need to run for 4 or 5 hours to test it)

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 ...

Dratted local minima (Rumours of the leak's demise are unfortunately exaggerated)

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 ...

Ding dong the leak is dead (The wicked leak, the wicked leak... though it's evil sister the database error is still threatening Dorothy...)

Well, it takes approximately 6 hours, but it does eventually reach a steady state for memory consumption. While waiting for it to stabilize I implemented the device-hierarchy. Unfortunately, I'm now seeing hard-hangs every once in a while on my machine (looks like yet another database-driven problem, as it's occurring just after the hierarchy import completes ...

2-hour test-debug cycles are annoying (Not enough time to do anything significant, not enough to work on another project, but way too much to just sit waiting...)

Been working on the memory-leak problem. Problem is, the system is supposed to "leak" memory for ~ 2 hours as it scans each modem and records it's values. I think I may have solved it 2 hours ago, but I really won't know for another hour or more (even then, the rate of the leak ...

Ah, the wonders of recursive searching (Search-within-a-search just drops in my lap...)

As mentioned last night, today's first order of business was to get seach working. At the moment this is limited to searching for modems. One of the key requirements, however (again, none of this actually laid out in the original spec, we just decided on Friday) is that search be such that you can optionally ...

Continue reading

That's it for tonight (Didn't get the search functions working yet...)

There are 3 user stories I'd like to get done for the demo; modem search, data graphs and at least one of the synthetic hierarchy types (devices). I'm about 1/2 done the search story now. The database-access bug on cmon is still keeping it from completing the requirements (i.e. running the full demo), but the ...

Need to find a way to distract myself (There's not a lot to fire the imagination at the moment...)

I'm considering purchasing an ATI TV Wonder to be able to use MythTV on this machine (we pay ~$50/month for cable TV and watch maybe 3 shows a week at the moment (yes, yes, I should be listening to lectures or something, but I'm out of philosophy lectures, and the music is *really* getting repetitive ...
