Of Mice and Computer Users

with 2 comments

There are days when I can barely suppress the suspicion that life is a weird cosmic joke, “Truman Show”, or scientific experiment that replaces mice in a labyrinth with humans in a Matrix.

Today is one of those days: I had cleared almost every task of my schedule in order to dedicate myself to the tax declaration for 2017—after having postponed it again and again for the last two weeks and knowing that it would likely leave me in too poor a mood to risk anything else that could aggravate me. (Cf. a number of earlier texts, e.g. [1].)

Then a server crashed, which I had had running for several weeks without problems. I rebooted it, started things up again, and decided to do some minor clean-up while still logged in. (Should have stuck to the plan…) In the process, I (very, very unusually) managed to screw-up a command, leading to all the files in the user account being moved. While I discovered this immediately after submitting the command, I could not interrupt it, because my session froze… After a minute-or-so of waiting, I forced a new reboot.

Less than thrilled, I proceeded to clean up the damage (and fortunately, no irrecoverable damage took place)—only to now have my notebook complain about a CPU being stuck and eventually freezing, forcing a reboot of the notebook… Only yesterday, I had noted an up-time of roughly sixty days—today, right in this already annoying situation, it fails! Worse, after the reboot, after I have got everything* back up again, the notebook just crashes. Roughly sixty days without problems and then two forced reboots in twenty minutes. Worse yet, I next decided to use the latest installed kernel,** seeing that I trailed heavily in version, and that newer kernels are usually better—and found myself needing yet another reboot within five minutes…

*With a number of different user accounts, different encryption passwords, and whatnot, this takes a lot more time for me than for the average user. Normally, this is not a problem, because I only need to reboot every few months. When I have multiple reboots in a single day, the situation is very, very different.

**At some point, the newest release became unstable with my notebook, and I set up my boot-loader to use an older, stable kernel per default. However, that was at least six months ago, running an older kernel is a potential security risk, and I had hoped that the current newest release would have resolved these problems in the interim. Unfortunately, this was not the case. Switching to a newer kernel in the above situation was, admittedly and with hindsight, pushing my luck; however, if I had not tried it today, the next “natural” opportunity might have been another sixty days into the future. (Indeed, going by my existing plan, I should have switched kernels already for the first reboot, but simply did not remember to do so until the third attempt.)

As of now, I have an up-time of a little more than four hours (back with the old kernel), and hope for another sixty-ish days. However: Half the day has been wasted between the extra efforts and the time needed to restore my mode—and I am not taking the risk of attempting the tax declaration today, lest things end with a notebook that crashes in a more literal sense (say, into the nearest wall).
