DECStation 3100 on a RPi2040...

by John Stoffel

My first real Unix workstation, reduced. https://github.com/rscott2049/DECstation2040 This brings back memories. I think they had 8mb of RAM and 525Mb 5 1/4" full height hard drives in external SCSI enclosures way back in the late 80s....

Re: You-Do-It Electronics is dead, long live You-Do-It Electronics

by Tim Keller

Sadly I only went to You Do it once and it was really amazing. It was before the pandemic in their full glory. My co-worker is a big ham guy and he needed some stuff to repair a couple radios as well as some connectors for his various antennas. He was in there all the time and immediately was greeted by a sales guy who dove right into a deep conversation about dipole yaggi's, etc. I wandered the aisles, just amazed. They had a pretty decent 3d printing corner as well. Sadly, I think the market for building your own electronics is continuously shrinking. Tim.

Keeping your package manager happy in Ubuntu and Debian -- from prior upgrade discussion

by Michael Voorhis

On 7/1/24 9:34 PM, gmcaplan--- via WLUG wrote: > John, Thank you for your help with my recent Linux problems. Sorry I > did not say anything sooner. I'm coming late to this discussion; sorry about that. Re: "old packages from a previous upgrade" ... in Ubuntu, the "do-release-upgrade" script is supposed to clear those out. But if do-release-upgrade crashes out, people can get lost as they don't know how to duke it out with the package manager. My standard "update the software" in Ubuntu/Debian looks for deletable and orphan packages specifically. Nuking orphan stuff and removing old cruft beforehand, is THE WAY to make your upgrades work better. The only other source of complication is old additional software repos in /etc/apt/sources.list.d/[...] which are NOT supported in the OS release you're upgrading INTO. Does your package manager want you to delete stuff? dpkg -l | grep '^r' | awk '{print $2}' | sort | fmt ... this command should return no output if your system is clean. Does your machine harbor software not attached to any software repo? (these are AKA "Obsolete packages") Learn the shocking truth: aptitude show '~o' | grep Package | awk '{print $2}' | sort | fmt ... this command should also produce no output on a happy machine, other than perhaps one-shot .deb files installed from downloads (i.e., if you download the zoom client by hand and install that without using a repo, etc). The more cruft, the worse your major-version-upgrade experience will be. The upgrade is performed entirely by the package manager, so that part of your OS needs to be happy before you can start an upgrade with confidence. --MCV.
