Complexity .....and Chess
by Gary 10 Nov '23

10 Nov '23

IMHO for a variety of reasons, a lot of people left the work force. This caused the labor pool to reach further down the bell shaped curve to find willing participants. Unfortunately, the complexity of the world, which in my opinion is too complex or perhaps overly complex or perhaps more complex than it needs to be, remained the same. As a result, many even moderately complex things are breaking. Like for example chess on Linux. I just spent most of my afternoon installing various chess programs, they don't really work. Some don't work at all. Some sort of work, but have various sort of major features that don't work. Gnome-chess works. But I can beat it easily. I haven't played for a while, and I'm not that good. It says I can install another engine. But it fails to tell me how and if I go out to Google, the features that it documents don't actually exit on the actual app. Actually brutalchess might work too. It has no man page and no menu of any kind. There is no documentation of any kind on the web page, but there is a forum and a mailing lists. You just move and it starts playing. It seems like it makes pretty good moves, but the display is hard for me to see and I can't change it. 10 years ago, this was easy and worked just fine. Granted, enthusiasm for chess has wained somewhat. Sigh. I'm just glad I don't have any brain surgery scheduled in the near future. I doubt if people are going to get smarter or perhaps less careless, overnight. But perhaps the world will simplify a bid. Eventually. That would be a good thing IMHO. -Gary

Fedora 38 and Fedora 25. I also saw chess.org has online chess, but I didn't take the plunge because I figured there would be ads. Maye I'll look into it, but I hate supporting the whole IoT nickel and dime philosophy that seems to be prevalent. I need a subscription to use my wireless camera. Really? -Gary On Tue, Oct 31, 2023 at 05:22:02AM +0000, Allan Heim wrote: > Apologies, I'm not a chess guy, but have you looked at https://lichess.org/ ?

Check this exploit out! "In our exploit, we simply fill our 6MB of environment strings with 0xfffffffffffffff8 (-8), because at an offset of -8B below the string table of most SUID-root programs, the string "\x08" appears: this forces ld.so to trust a relative directory named "\x08" (in our current working directory), and therefore allows us to load and execute our own libc.so.6 or LD_PRELOAD library from this directory, as root." Is that wild or what? I was checking the changelog.txt for Slackware 32 bit. l/glibc-2.37-i586-3.txz: Rebuilt. Patched to fix the "Looney Tunables" vulnerability, a local privilege escalation in ld.so. This vulnerability was introduced in April 2021 (glibc 2.34) by commit 2ed18c. Thanks to Qualys Research Labs for reporting this issue.

Auto Mounting with Systemd
by Linus Sphinx 05 Oct '23

05 Oct '23

They seem to have changed the hierarchy of autofs config files or something and it just stopped working for me. Looking for what changed and ran into systemd.mount on stack exchange. Short form: write an entry in /etc/fstab like this: nas:/data/directory /home/me/nas nfs nfsvers=4,nofail,x-systemd.automount 0 0 To activate this entry immediately, you would need two commands: # systemctl daemon-reload # trigger systemd-fstab-generator to re-make *.mount and *.automount units # systemctl start home-me-nas.automount #start the newly created automount unit or just reboot. $ man systemd.mount $ man systemd-fstab-generator Reveal much about units created, still playing with it. The above lines clipped from: https://unix.stackexchange.com/questions/671486/rhel-8-3-autofs-not-mountin…

Anybody else using autofs on NFSv4 mounts. Ever heard of doing it with systemd? https://unix.stackexchange.com/questions/671486/rhel-8-3-autofs-not-mountin…
