Software problem: Deleting Btrfs subvolumes
Internet is no longer full of Btrfs horror stories so I decided to use Btrfs when I reinstalled my desktop computer with NixOS. It has some nice features, like subvolumes, compression and cooperation with Podman. I still prefer ZFS but due to its weird license it’s not included in Linux and one can fall into […]

Software problem: Compiling Emacs vterm module on NixOS
I started using NixOS again some time ago. The fact that NixOS doesn’t use Filesystem Hierarchy Standard is sometimes a big source of pain and complications. One non-obvious thing for beginners is how to compile a C program. One C program that is very useful and must be compiled locally is emacs-libvterm C module, providing […]

Software problem: Music players on Android
One might thing that making a program that plays music stored locally on a computer shouldn’t be that difficult. It must be able to find music files, to play them correctly, to play songs in the correct order, and provide a decent user interface, with some search capabilities. Considering that the most difficult tasks can […]

Software problem: Missing virt-manager icons
virt-manager on my NixOS system was missing icons on most of its buttons, making the application handling somewhat difficult. A little stupid annoying problem, apparently of category 3, has wasted several hours of my life. I reported it as a NixOS bug. NixOS people responded quickly and were helpful so after a couple of days […]

Software problem: Lost network in a Podman container
I use Podman for running various stuff. It’s sometimes challenging due to problems of all categories. One special problem I experienced on one of my computers was that if a container had stopped and then was started again, it lost its network interface, only loopback interface remained available. I searched the web and hoped it […]

Software problem: KDE Wallet
When I reinstalled my desktop computer, KDE started asking me for a wallet password. Each time a short while after I started my web browser. It didn’t look all right: I don’t think I’ve ever set a wallet password and I deleted whole KDE configuration after I had reinstalled the computer. I couldn’t see any […]

Software problem: Wahoo mobile application
I wanted to make a bike trip, planned it on komoot and, just before the trip, tried to synchronize the route to my Wahoo ELEMNT. It didn’t work, the Wahoo device couldn’t connect to WiFi. WiFi problems with Wahoo are not uncommon so I tried to use Wahoo mobile application to download my route. The […]

Software problem: Emacs windows not properly maximized
I don’t like wasting screen space so the very first configuration action I do in newly installed desktop environments is making all windows maximized by default. After I had reinstalled my computer, I experienced a problem that new Emacs windows (or frames, in Emacs terminology) created after Emacs had started were not fully vertically maximized, […]

Software problem: DKIM
I managed to waste my time on another thing. I foolishly thought that I should finally add DKIM to my mail server. Configuring it in the mail server was relatively easy. But once I started to check whether it actually works, I’ve fallen into trouble. I started with the elliptic curve algorithm (ed25519). OpenDKIM on […]

Software problems (and rsync failed to set permissions)
I regret that I have little opportunity to work on free software outside my job these days. One of the reasons is that I have been struggling all the time with things that don’t work, a significant part of them being software problems. Software problems can be categorized into three groups: User stupidity problems Software […]
