Lies, damn lies, and statistics

There are three kinds of lies: lies, damned lies, and statistics.

I don't normally head over to Groklaw, but I did recently based on some other links and came across an article about a study conducted by Microsoft on how developers don't want the GPL, version 3, to "police patents." If you dig a little deeper into the study, the following facts about the study are exposed:
  1. It was conducted by email.
  2. 354 emails were sent out between Feb 28 and April 4 2007.
  3. 332 reached their destination.
  4. 34, or slightly more than 10%, responded.
Now, PJ chose a particularly inflammatory (some might even go so far as to say trolling) title: "Only 11% of OS Targeted Programmers Willing to Help MS-Funded Study." And that's because Microsoft did indeed fund yet another study seeking to bolster their position with regards to the GPLv3. I don't see it quite that way. I see that only 10% of the targeted group (according to my simple math skills) bothered to respond (frankly, for reasons unknown). And those 34 bear the heavy responsibility of representing the rest of us who either refused to respond or who were never even contacted. Great responsibility indeed.

Do I feel pity that Microsoft's efforts were misconstrued yet again? Hell, no. Microsoft has a long history of lying, cheating, and outright theft in the accomplishment of its singular goal of total domination in all markets it wants to play in. Microsoft went looking yet again to buy more support for their position with regard to the GPLv3. And Microsoft got sloppy in deciding to run with this particular study. Every Microsoft 'study' been pretty dodgy to my eyes, but this one seems the worst by far. This particular study is based on only 10% of it's statistically significant sample group. And I'm assuming, based on my ancient statistics classes from some 30 years ago, that 332 (not 34) is the minimum population size required for the study to have any relevance. So if you only got a 10% response from your relevant group, how can you really draw any conclusions?

The one conclusion that I can personally draw is that those that did respond are the ones who have an issue with GPLv3. Which means that I can interpret the statistics to mean that out of 332 potential respondents 298 (90%) did not have a problem with GPLv3 and so did not bother to respond. I also wonder that when the initial request went out if the potential respondents were told that Microsoft was funding the study. Would more have responded if they knew? I would have just to make sure my opinion was at least recorded. And I believe many others would have as well. But if it went out as a low-key request to respond to these questions, then many would have read it and tossed it as one more thing to try to shove into an already busy schedule. And so it got dropped on the floor.

The PDF of the paper is here. I'm going to read it and see what the paper's authors really said, and read their own words about how they interpreted the results. I don't trust the eWeek article sited by Groklaw, and I've learned not to trust PJ's interpretation either. Just like I've learned to question just about everything Microsoft says.

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.

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…
