NetBeans 6 Beta 1 running on a constrained system

In an earlier post dinesh left a comment complaining about the poor performance of NetBeans 6 on his system as compared to earlier versions. This led me to upgrade my version rhea, the Ubuntu 7.04 test system, to NetBeans 6 Beta 1 from Milestone 9. I also upgraded to Java 6 Upgrade 2. I then started NetBeans 6 and ran some simple tests to see how well it performed on the desktop. rhea has "only" 512MB of DRAM like dinesh's system. The processor is a single-core 32-bit Athlon XP 2500+ running at 1.8 GHz. dinesh's was a dual-core Pentium 4.


  • Running NetBeans with Firefox is a mistake, especially if Firefox has been up for some time and has multiple tabs open. The keyboard response was horrible. This may be part of dinesh's issues with regards to performance. Of course running anything substantial with Firefox on this machine has been horrible, which is a shame.
  • Once Firefox exited the response in NetBeans 6 was quite good. Even after restarting Firefox the response stayed snappy. I was able to enter text, search for text, and compile and run the application with no issues and in a very timely way.
One other note. I installed the Nodoka theme from the openSUSE factory (funny, that). The controls are from the Nodoka theme, but the window border is not. And the only reason the window border isn't Nodoka is because it didn't show up when the theme was installed. I discovered Nodoka when I booted Fedora 8 Test 2.

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…

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…

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.
