Nano-review of Ubuntu 7.10 alpha 5

Downloaded, burned, and booted into Ubuntu 7.10 alpha 5 just to kick the virtual tires. Impressed over all with the quality of this alpha release, and I can see (and appreciate) where Canonical is going with Ubuntu. Looks like lots of work under the hood, with subtle but very important changes to the desktop. Tools are also beginning to show maturity. I am truly glad that there is now an Appearance Preferences application that combines Theme, Background, Fonts, Interface, and Desktop Effects all in one spot. After using it for five minutes all I can say is why did it take so long? It might seem insignificant but it sure helps to quickly tweak and tune the look of the desktop.

The screen shot above shows both promise and a problem. First, the promise. Europa, the system on which this live CD is running, has an aging ATI 9700 Pro video card. The free version of the ATI video driver as delivered was able to enable graphical effects previously associated with Compiz and Beryl. In fact the idea of Compiz or Beryl is noticeably absent. Which is as it should be. The effects should just be quietly and reliably working away.

With the open driver included, OpenGL is enabled by default. That's the whole point of firing up glxgears. But glxgears illustrates a minor problem. You see two sets of gears not because two glxgears instances are running, but because the one instance was moved across the desktop. For whatever reason glxgears' drawing canvas is not properly synchronized with the rest of the application's window. Drag it around and it leaves artifacts on the desktop. It's certainly no show stopper, but it should be looked at and fixed before release. Oh, and glxinfo states that direct rendering is enabled ('yes'). And the frame rate from glxgears is an order of magnitude faster than when running on openSuse with the ATI binary-only drivers. I don't know how well Google Earth would operate, but in the past you needed to install ATI's and nVidia's binary-only drivers to get decent performance out of Google Earth. Which paradoxically killed glxgears' performance compared to the open version of the ATI driver.

Other little things I noticed are the jumping windows. Click on a window behind another, and the top-level window(s) jump up and then behind the window you clicked. It's cute, but the cuteness wears off real fast. Like the wobbly windows, which mercifully are only enabled when you select the Extra effects radio button on the Desktop Effects tab of Appearance Preferences. If I may offer a suggestion to the developers, would you please add the jumping windows to the Extra effects selection. The shadows and translucency are more than enough for normal effects, and produce a truly lovely desktop experience. Or better yet, allow the end user the ability to fine tune (select) individual effects in the Normal and Extra effects categories.

I believe Ubuntu's next release will once again raise the standard towards an excellent user experience on the Linux desktop. I look forward to updating rhea's current Ubuntu 7.04 installation with the next release, 7.10.

Oh. This post was made in the live session. It's slow when starting an application off the CDROM, but otherwise the experience is indistinguishable from an installed instance of any other distribution.


  1. Nice review, not to scientific but still interesting ;)

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…
