More fun with EXWM
I have recently started using EXWM, an Emacs window manager. It’s very useful as a window manager itself but it also provides additional functionality and opens new possibilities. Starting EXWM automatically in KDE EXWM allows, similarly to other window managers, replacing an already running window manager. Now I’m confident about it enough and start it […]

Using EXWM
I sometimes miss useful things. For example, many years ago, I missed emerging Org Mode, not recognizing its potential, only to discover some years later how essential tool it is. And the same happened to me with EXWM, an Emacs window manager. I’ve always thought that making a window manager in Emacs is a crazy […]

Emacs tabs as workspaces
I used to use Emacs frames as workspaces. But reading through Emacs 28 NEWS reminded me that tab bars could be probably better used for the purpose. And indeed, using tab bars is simpler and looks like a very good fit. First some initial settings: (tab-bar-mode 1) (tab-bar-history-mode 1) (custom-set-variables ‘(tab-bar-show nil)) (tab-bar-rename-tab “emacs”) They […]

Learning Haskell
Learning Haskell has been on my to-do for maybe about 10 years. I’ve already made several attempts but have never had an opportunity to finish them, starting again and again from time to time. Haskell is not something one can learn in two afternoons. My latest attempt has finally succeeded and I have basic knowledge […]

Learning Rust
Many programmers like learning programming languages. It’s fun to discover new concepts and possibilities and to be able to use them to write more elegant, more powerful or more efficient programs. I had enjoyed this activity too, until I discovered Common Lisp many years ago. Once I learned Common Lisp, my passion for learning new […]

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 […]

Debian builds with Podman
Since I no longer have Debian on my desktop computer, I had to arrange an environment for building Debian packages. I could use a virtual machine running Debian for that purpose but this would have several disadvantages: It would consume unnecessarily much resources. I would have to use a nested build environment such as cowbuilder […]
