Running SQLite in production (yes, really)

Wed, 22 Jul 2026 00:00:00 +0000

I recently shipped a small Flask app, a scoring platform for a fitness competition, with SQLite as its only database. Not as a stopgap until the real database arrives: the app refuses to start with anything else, because a half-supported second database is worse than none. The conventional advice says this is a mistake. For this class of app, the conventional advice is wrong, but the deployment details will bite you if nobody warns you about them.

When RAID1 saved the data but not the state

Mon, 12 Jan 2026 00:00:00 +0000

My home server is a ZimaBoard 2 running ZimaOS. The storage that matters is a RAID1 mirror, two 4 TB drives formatted BTRFS, holding a media library, backups, and personal archives, with the Docker application stack running off the same pool. It is a small setup, and for a long time it was a boring one, which is exactly what you want from storage.

Then a migration went wrong, and it taught me more than a year of everything working ever did.

Installing Hugo on WSL

Wed, 22 Jan 2025 00:00:00 +0000

If you develop on Windows but want a Linux toolchain, Hugo runs happily under WSL. Here is the quick version, plus the one gotcha worth knowing.

The quick way (often out of date)

Update your package list and install from apt:

sudo apt update
sudo apt install hugo

This works, but Ubuntu and Debian package a version of Hugo that usually lags well behind the current release. Themes move quickly, and plenty of them need a newer Hugo than apt will give you. If a theme’s build complains about your Hugo version, this is why.
