Memory issues: Firefox 3.0.2 and Mandriva 2008.1

I've still got Mandriva 2008.1 installed on europa, the aging 32-bit Athlon XP system, and I'm running Firefox 3.0.2 I had downloaded from Mozilla and installed (untarred) into my home directory. Up to this point I've not had any memory issues, but today I happened to look up at the system monitor running in my upper panel and saw that a good chunk of the 2GB of system memory was consumed along with 1GB of swap. So I opened system monitor, then exited Firefox and watched memory consumption. Sure enough nearly all swap was recovered as was nearly 1.75GB of system memory.

Normally my Mandriva box stays up all the time along with a single instance of Firefox with multiple tabs, and I don't usually have any problems. Firefox this time had 21 tabs open, which is not a lot for me.

The image to the right shows memory usage right before I exited Firefox. I let the system sit 'idle' for a few moments before I restarted Firefox again. You can see the corresponding network activity on the lower right, with a very modest increase in system memory consumption. Then it settles down. I have no real idea what caused it, but it would seem that there are still a few corner cases with regards to memory leaks within Firefox 3. I wonder if the developers have killed a few more memory leaks for 3.1 without introducing any new ones. I guess we'll see.

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…

vm networking problem fixed

Over the weekend I upgraded to Windows 8.1, then discovered that networking for the virtual machines wouldn't work. Then I tried something incredibly simple and fixed the problem.

Checking the system I noticed that three VMware Windows services weren't running; VMnetDHCP, VMUSBArbService, and VMwareNatService. VMware Player allows you to install, remove, or fix an existing installation. I chose to try fixing the installation, and that fixed the problem. The services were re-installed/restarted, and the virtual machines had networking again.

Once network connectivity was established there was exactly one updated file for Ubuntu 13.10, a data file. This underscores how solid and finished the release was this time. Every other version of every other Linux installation I've ever dealt with has always been succeeded by boatloads of updates after the initial installation. But not this time.

Everything is working properly on my notebook. All's right with the world.

sony's pivotal mirrorless move

I'm a died-in-the-wool technologist, even when it comes to photography. I have always been fascinated with the technology that goes into manufacturing any camera, from the lenses (optics) through the mechanical construction, the electronics involved, and especially the chemistry of the film and the sophistication of the digital sensor. It's amazing that the camera can do all it's asked of it, regardless of manufacturer.

Of all the types of cameras that I've really taken an interest in, contemporary mirrorless (again, regardless of manufacturer) are the most interesting because of the challenging problems the scientists and engineers have had to solve in order to build a compact but highly functional camera. In particular I've followed the sensor advances over the years and watched image quality climb (especially with μ4:3rds) to exceed film and rival one another such that there's very little difference any more as you move from the smaller sensors such as 4:3r…
