Gary, computers are hard and shouldn't be used by retired folks. :) Run it like below, it will load last. Use AI for docs - much easier and faster than our brains. Type=idle Behavior of idle is very similar to simple; however, actual execution of the service program is delayed until all active jobs are dispatched. This may be used to avoid interleaving the output of shell services with the status output on the console. Note that this type is useful only to improve console output, it is not useful as a general unit ordering tool, and the effect of this service type is subject to a 5s timeout, after which the service program is invoked anyway. https://www.freedesktop.org/software/systemd/man/latest/systemd.service.html Kevin

playing BluRay

I didn't think playing BluRay on Linux was doable, yet I got it working! I used the script `aacsdb-update.sh` to download the VUK for known BluRay disks. https://gist.github.com/CPT-GrayWolf/c26446298bc769238b349165a051e4b1 Plus, I installed the aacs packages. ``` sudo dnf install libaacs-utils libaacs-devel ``` # This allows Blu-Ray disks who's VUK is known # to be played on systems using libaacs Then, I set `JAVA_HOME` environment variable for my system. ``` export JAVA_HOME=/usr/lib/jvm/java-21 ``` Then I launched vlc and opened the disk (Top Gun) at /dev/sr0. It's title is in the VUK database. It plays! More info on BluRay in Linux is available on the Arch site. https://wiki.archlinux.org/title/Blu-ray#Playback Brian -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

Raley's on Freeport
by Brian E. Lavender 18 Jan '26

18 Jan '26

Future meeting location ideas. Does anyone hang out at the Raley's on the Freeport? They have the mezzanine area. I was thinking we could do a social there. I realized that I could actually bring another monitor and plug it into my system. That way we could just have people on both sides of the table. -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

January General Meeting We will continue at Kupros for January. If anyone has a different location in mind for February, please let me know. https://www.saclug.org/articles/2026/january-2026.html When: Tue January 20, 2026 06:30 PM to 08:30 PM Speaker: You Location: Kupros We will meet back at Kupros for this meeting! The last meeting we had, some noted that it was too loud. I had been thinking about a different location, but I didn’t investigate, so we will continue at Kupros for now. Bring your gadgets, laptop, etc., and we will discuss, evangelize and strategize the upcoming meetings. We usually congregate on the second floor. Look for a penguin printout or hackers with their laptops open. Brian -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.
