Xorg stuff
by Brian E. Lavender 17 Nov '25

17 Nov '25

While downloading F43 updates for my desktop, I found this thread on Xorg. Admittingly, I still do not fully understand how the windowing manager all fits together. I take it that there are various X libraries? https://discussion.fedoraproject.org/t/f43-change-proposal-x11libre-system-… I thought this quote was interesting: "Fedora will benefit from shipping an actively maintained Xserver instead of a moribund one whose maintainers themselves label as “unmaintained” (pushing Wayland as the replacement)."

dnf cache
by Brian E. Lavender 15 Nov '25

15 Nov '25

I was looking at a way to cache packages for Fedora. I recall apt-cacher for Debian. It appears that one needs to create a shared file storage repository to cach packages. I just scanned the article. Anyone have a cache configured for Fedora packages? https://fedoramagazine.org/use-the-dnf-local-plugin-to-speed-up-your-home-l… Brian -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

Fingerprinting
by Gary 19 Oct '25

19 Oct '25

I recently had some issues with an old install, fc 25, and espeak. As a longer term solution, I'll upgrade the OS. But, I got some nice AI help in fixing my current install in the meantime. Although some sequences were out of order, and things like that, given the different functions involved, it saved me a lot of reading and research. But, I'm digressing. During the troubleshooting process, it occurred to me that it would be nice to know what my settings had been and how the espeak app was functioning before it just stopped, for no apparent reason. I was wondering if "fingerprinting" an app on the system is a common thing, or just too much effort to get anything useful in the end, and what other people are doing.

AI revisited
by Gary 24 Sep '25

24 Sep '25

I find that in the evening, sometimes, I enjoy exploring a topic with AI for an hour or two. If done right, it can be very informative, and well, relaxing. I started to wonder, "Why didn't I do this with regular old Google?" Then I remembered that I did. Maybe 10 to 15 years ago. Back before the search results go so bad. By bad I mean tilted a lot toward selling you stuff as opposed to providing you with information. That took all the fun out of Googling for things. And, something else must have changed, because the results became much less diverse and it is harder to get around the just plain stupidity that occurs naturally :) But, I can't help wondering if, or perhaps when, the public and free AI will become the same way. Perhaps you will be able to pay for "better" AI, just like ca ble TV used to be. But, it will end up being the same, only different LOL. Jus t like cable TV. I guess there is no way to avoid it :( But, in some ways, it is a trip down memory lane LOL.
