2025: Music

I love year-review posts with recommendations so here is some music that mattered to me in 2025. Some I a) listened a lot to in 2025, b) discovered in 2025, c) re-loved in 2025 or d) just want to make you try. Sometimes I picked single songs, do try other songs of the artists too. [ ]

Calculate the percentage of cells per value category in a raster in QGIS

Kristian Evers asked on the fediverse: I have a raster where each cell is categorized with a value of either 1, 2 or 3. In #QGIS, how would I determine the percentage of cells in each category? This piqued my curiosity so here you go! The Raster layer unique values report tool provides both a [ ]

Converting lots of audio files to lower quality with soundKonverter

Notes for myself but maybe useful for *you* too? https://github.com/dfaust/soundkonverter Add your directory or directories, let it scan. For music select Opus with 48 kbps if that s enough for your use case. Create the file list, then fix special characters with https://github.com/dfaust/soundkonverter/issues/96: sed -i 's/file:\/\///; s/%20/ /g; s/%23/#/g'…

Copying files to a Fenix 6S on Archlinux

Make sure its USB mode is set to MTP mode, not Garmin mode. Watch dmesg to see when the device is connected and ready: [Fri Jun 28 15:27:59 2024] usb 1-2.1: new high-speed USB device number 36 using xhci_hcd[Fri Jun 28 15:27:59 2024] usb 1-2.1: New USB device found, idVendor=091e, idProduct=CENSORED, bcdDevice= 0.01[Fri Jun 28 [ ]

Waveshare Pico-RGB-LED with a Raspberry Pi via Thonny on Archlinux

https://www.waveshare.com/wiki/Pico-RGB-LED is horribly broken and this was hard to Google so hopefully this helps *you* or future-me. I did not manage to put the display directly on top of the Pico as a hat. Also my display s board has its pins numbered and labelled mirrored when comparing to the official pin out. FFS !? Install pico-sdk [ ]

moOde audio player 8 on a Raspberry Pi 3 Model B Rev 1.2 with Hifiberry Amp2 1.1

It s super easy but watch out because volume levels are messed up (super loud on tiny volume values!). Flash the image with RPI imager (enable SSH) /boot/config.txt might need dtparam=audio=off but I don t remember, try without that change. Boot the device Visit http://moode.lan (or fix your network, use the IP etc) and click m -> [ ]

Remotely controlling QGIS through PostgreSQL queries 🤪

I just wanted to see if it was possible, it is not a sane thing to do. PostgreSQL has a notification event system where you NOTIFY on a notification channel and clients can LISTEN for events. QGIS already supports this for a convenient, remotely triggered refresh function of PostGIS layers by listening on the qgis [ ]

Plugin options and QGIS3.ini

In the spirit of learning in the open: All the docs say is It is recommended to give some structure to naming of keys. The [PythonPlugins] section uses the plugins directory names and shows if a plugin is activated or not (true/false). Plugins can store their options anywhere. No really. Anywhere! You will find some [ ]

Backing up Hetzner snapshots locally

Hetzner is a nice, cheap host for server. Unfortunately they do not let you download backups and snapshots of cloud servers locally. So you are kind of locked in with them. Here is how I create full disk backups for e.g. standard CX11 servers with default images. Make sure you understand everything before you attempt [ ]
