axdigi resurrected
Seems funny to talk about 20 year old code that was a stop-gap measure to provide a bridging function the kernel had not (as yet) got, but here it is, my old bridge code. When I first started getting involved in Free Software, I was also involved with hamradio. In 1994 I release my first…

Displaying Linux Memory
Memory management is hard, but RAM management may be even harder. Most people know the vague overall concept of how memory usage is displayed within Linux. You have your total memory which is everything inside the box; then there is used and free which is what the system is or is not using respectively. Some…

pidof is a program that reports the PID of a process that has the given command line. It has an option x which means “scripts too”. The idea behind this is if you have a shell script it will find it. Recently there was an issue raised saying pidof was not finding a shell script.…

Forking processes and Gtk2
I made a change recently on the gjay program. gjay is a gtk program that basically analyzes your music and makes playlists.

The output of ps changed depending if a different option had a hyphen before it or not. First, the expected output…

Be careful with errno
I’m getting close to releasing version 3.3.11 of procps. When it gets near that time, I generally browse again the Debian Bug Tracker for procps bugs. Bug number #733758 caught my eye. With the free command if you used the s option before the c option, the s option failed, “seconds argument ‘N’ failed” where…

Linux 4.0 ate my docker images
I have previously written about the gitlab CI runners that use docker. Yesterday I made some changes to procps and pushed them to gitlab which would then start the CI. This morning I checked and it said build failed – ok, so that’s not terribly unusual. The output from the runner was: gitlab-ci-multi-runner 0.3.3 (dbaf96f)…
