Computer Woes

My primary Windows machine is glitching. This morning, it woke up dead. Or rather, I woke up to find it in a zombie state, with power on but no video signal. I couldn’t even do a hard reboot.

I shut it down for a while, than powered it up, at which point it booted. For a few minutes. Then mouse and keyboard froze, and I had to power down again. After repeats of this, with different applications running, I came to the conclusion that it’s a hardware problem, most likely some component on the motherboard overheating. The fan seems to be running all right, but the CPU seems like the most likely suspect to me. Are there other reasonable possibilities? It’s really bad timing, because I’ve got some data on that machine that I need for some deadlines today.

I’m posting this from my Fedora box.

[Update at 9 AM EDT on a rainy south Florida morning]

I managed to get it up just long enough to drag some files over to the other machine, but I suspect it will be a long slow process in continuing to reboot it until I get everything I need. I really need to set up a nightly cron job to automatically back up to it.

In response to questions in comments, the cabinet is open, the fan is running (though I don’t know it it’s at an adequate speed), and the (Athlon XP) processor is running at its default speed of 1.8 Gigahertz (no reason to overclock this machine–I just use it for office work).

It’s now gotten to the point at which I can’t do anything useful with it–it bluescreens shortly after logging in. It’s been fragile for a while, often locking up or bluescreening randomly, or occasionally right after boot, but whatever the problem was seems to be coming to a head. I’ll try swapping out fan/CPU, because that seems like the most likely source of the problem. I’ve been wanting a faster processor anyway. But probably not today–no time to mess with it

Predictions Of The Future

From the past.

Some of them held up pretty well, and some of them didn’t really happen until the twenty-first century, and some haven’t panned out at all (like using electric currents to encourage plant growth, and the quiet cities). Slightly subsonic electric ships don’t seem likely to happen any time soon, and pneumatics came and went, being used only for niche applications. Still an interesting set of prognostications for the time.

[Update a few minutes later]

D’oh!

As Paul Dietz points out in comments, they’re only calling for ships that go a mile a minute. I was somehow thinking ten miles a minute (close to sonic velocity). Don’t ask why I was thinking that–I don’t know. Yes, sixty miles an hour is theoretically possible, but it’s high power consumption.

There’s A Lesson Here

Via NASA Watch, an interesting article about SETI:

Denounced a decade ago as a misguided effort to find “little green men” and cut off from government funding, SETI, which stands for search for extraterrestrial intelligence, has found a new following among Silicon Valley titans and techies elsewhere who are interested in space. They have infused the institute with money and unconventional technical ideas, bringing a new respect and energy to the organization. Some argue that being cast away by the federal government was the best thing that could have happened to SETI, that it has become stronger and more innovative in the private sector than it ever could have as part of a public bureaucracy.

More of this, please, particularly for human spaceflight.

“Unwarranted Self Regard”

One fears for the future if these students are typical of today’s crop:

Once again, I explained how to answer the question, and once again the student was pleased. The error was just a trivial difference of opinion. “Yeah, I get it,” she said. “I was just thinking of it differently.” You say tomayto, I say tomahto.

No, I wanted to say, you weren’t thinking of it differently, you had it completely wrong; you didn’t understand it at all. But like her many compatriots, she was unlikely to acknowledge that, or admit to a mistake even when she created a version of reality never seen on a map, or in the actions of a blackbird.

Students have always deluded themselves, of course, and hope has always sprung eternal, or at least until final grades appear. And at least some in my classes really do eventually master the material. But confident placidity in the face of error seems to be on the rise.

Maybe it’s all that self-esteem this generation of students was inculcated with as youngsters, or maybe it’s the emphasis on respecting everyone else’s opinion, to the point where no answer, even a mathematical one, can be truly wrong because that might offend the one who gave it.
