Python and SysV shared memory
At work-work the system uses, for historical reasons, a lot of SystemV shared memory. The SysV shared memory API has C functions like
shmat(2). There is also a different shared memory API, POSIX shared memory, which has functions likeshm_open(3). For reasons, on some work-work systems we’re constrained to Python 3.7 and no additional libraries. I wanted to mess with the shared memory on such a system, from Python for convenience, so I wrote some very simple wrappers. Here’s a recap. -
Plasma6 and FreeBSD 14
I just installed a new FreeBSD desktop machine. For this one, I wanted to have KDE Plasma6, since that’s already running on my Linux laptop and gaming machine – and it’s time for me to dogfood on FreeBSD. Here’s some notes.

KDE Plasma Wayland keyboard layouts
Calamares is a Linux system installer used by dozens of distro’s to get the bits from an ISO image onto a target computer. Development is nowadays purely on a volunteer basis, which makes it hard to keep up with all the changes in the Linux world. But steps are made, and code submissions are very welcome, and here’s a note on something relatively new and useful: Wayland keyboard layouts.

Message-passing APIs (SIMPL)
In the KDE world, famously there was that weekend where DCOP (Desktop Communicating Objects Protocol) was created, setting the stage for things like KParts. GNOME picked the CORBA object model, and much later the Free Desktop world settled on DBus as a message-passing API. But even at the time, there were other message-passing APIs. At work-work I use one, called SIMPL, which is kind of shout-out to the late ’90s of DCOP.

GPG Key Update
Quick note that the yearly extend-the-expiry-of-my-GPG-key has happened early this year, as I realised that my GPG information on FreeBSD infrastructure was outdated. This doesn’t extend the Calamares signing-subkey (not yet) but does add new EC subkeys if that’s your kind of thing. The Calamares signing-subkey is valid until November 2024.
