At Work With Linux: Ubuntu 11.10 and a Problem Explained, Somewhat


You're looking at the Software Center, working again. I complained about its not working and spewing out an error message. I blamed it on Ubuntu, and I was probably wrong to do that. It turns out it's not a problem with Ubuntu but in this particular case the environment in which it's run.

My instanced of Ubuntu 11.10 is running as a VMware virtual machine. This particular screenshot of Software Center running is after cold starting the instance. You can either shut down a VM or you can just put it to sleep, then restart the VM where you left off. And that's the key to the malfunction.

I was hoping that another upgrade might have restored Software Center. To complete the installation I restarted Ubuntu and after the reboot found Software Center was indeed working again. I put the VM to sleep, then came back to it later in the day and discovered that Software Center was back to it's original failure mode. And then the lightbulb came on.

I shut down the VM, then restarted it. Software Center worked. I did that a number of consecutive times, and Software Center started correctly each and every time. But every time I put the VM to sleep and then restarted it from sleep mode, Software Center always failed to launch.

At this point I don't know if I'll file a bug report or not. My way of running Ubuntu 11.10 is, shall we say, non-standard. But I'm curious if Ubuntu would illustrate the same behavior if it was installed on a tablet and went through the same style of sleep mode. On wake-up, would Software Center fail on in the same way, for the same reason? I supposed I could dig deeper for a full explanation and a solution, but right now the quirk is logged along with a simple solution: reboot after using Software Center in a VMware VM. It's not what I would call a show stopper, and I've got bigger problems and little time.

Now, on to other things...

  1. Thanks for this explanation! Having the exact same issue running Ubuntu 11.10 with VmwareFusion on the Mac.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

first night for the gingersnaps

The first night has passed and the two have managed to survive, in spite of what their tiny hearts might have thought when first arriving. Greebo, the larger of the two, has been in hiding the entire time so far. Ponder has spent the time zipping in and out of hiding spots, checking things out, and learning just how comfortable pillows are for resting your head.

During the night I felt the tiny body of Ponder hitting the bed as he leaped up on the side, and then climbed to the top to run around on top of me. At least once he play-attacked my fingers. He might be small but his claws are still quite sharp.

When I got up in the morning the bowl of cat kitten food was fairly well depleted. It's been refilled and fresh water put in the big dish on the floor. I'm assuming that both Greebo and Ponder are feeding and drinking. I have seen Greebo under the furniture peeking out at me when I went looking for him. I'm leaving him alone while he continues to adjust.

So far the guys h…

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…
