Tailscale SSH

Published on in 👨‍💻 Dev

I finally got around to using Tailscale SSH. I’ve been using Tailscale for over a year to access my servers via SSH (my VPS is even available via Tailscale only), but I haven’t used the new Tailscale SSH feature yet.

“Friendlier SQL with DuckDB”

Published on in 🔗 Links

I come into contact with SQL almost every day, be it at work (Oracle Database) or while developing my blog software (SQLite). I don’t find SQL as bad as some others might, but sometimes SQL could be better.

To kick off my few days of Easter vacation, I took my freshly inspected and repaired pedelec (e-bike) with beautiful weather (20 degrees and sun) and drove a round on the “Ringgleis”, a bike path around my city. The total mileage has now also finally reached the 3000 km. That’s still not much over several years, but I still have my second, non-electric bike, with which I probably ride a lot more.

How I checked the battery health of my Android phone 🔋

Published on in 📱 appydroid

“The totalitarians of the attention economy”

Published on in 🔗 Links

I mean. Fuck. Is that really what we’ve been reduced to? A set of eyeballs (or earballs??) to be squeezed until every last tear of attention is drained. The image of human batteries powering the simulation is barely a metaphor at this point.

What matters when Blogging

Published on in 💭 Thoughts

If you’re running a personal blog, then it doesn’t matter how often or how much you blog. I think these points are much more important:

Just a small comparison to show that many websites are completely obese: My bachelor thesis in PDF format (which I handed in yesterday) has a size of 1.4 MB. It contains several images and 85 pages of text. With a high information density, this is a much smaller size than most websites have. And it would have been probably also possible to compress or optimize the PDF further.
