I can’t really explain why this is happening, but I noticed that my home server is now idling at 7 watts instead of 13 watts as before. I checked powertop, and it seems that the CPU is staying at C7 (pc7) for about 85% of the time, which seems to be the most power efficient state.

Maybe it’s a result of moving my Baïkal instance to my VPS or some other updates? Maybe Home Assistant or Tailscale? The operating system is still Ubuntu 22.04. What else could explain almost 50 percent power reduction without any hardware or major software changes?

Update: I found a likely source: When the powered-off TV is connected with an HDMI cable to the DisplayPort adapter plugged-in into the home server, it idles at about 13 watts. When I remove the HDMI cable from the DP adapter, it goes back to 7 watts. So it might have to do something with the integrated GPU. I guess, I will leave the TV disconnected unless I really need it.

Reviving Memories: A nostalgic bike ride past my University

It was a bit cold and quite windy today, but otherwise the weather was beautiful with a clear and sunny sky.

I took advantage of this opportunity and used my pedelec again after a long time to do what I originally bought it for.

I bought it in 2018 (German blog post from back then) so that I didn’t always have to drive to university by car. I sometimes took the bus or train, but the public transport to the neighboring town 15 km away (Wolfenbüttel) wasn’t that great and the journey took a long time, especially at off-peak times (for example in the evening after the last lecture). A normal bike wasn’t a good alternative for me either, as I didn’t want to sit in the lecture hall sweating.

Anyway, today, after a very long time, I cycled past the university where I studied from 2017 to 2021 and completed my bachelor’s degree in computer science. From 2020, mostly just from home, pandemic and all…

It was kind of cool to stop by there again, I got a bit nostalgic. But I’m also kind of glad to have the degree behind me, as I mostly saw it more as a necessary prerequisite for my favorite job.

I’ve made the sad observation that numerous people started to blog during the pandemic, but stopped in 2021 or 2022. Today, I cleaned up my feed subscriptions in Miniflux and removed many feeds that saw no activity for a long time. At least, I can’t remember of a site I subscribed to that completely disappeared.

I just noticed that I can cancel my annual Amazon Prime subscription and get the remaining time refunded. It was a very hidden option, but I just chose it. Delivery to package stations is still free. Let’s see if I can survive without Prime. In the last 12 months, the only Prime feature I have used is delivery. And I ordered about 40 times, but often just for convenience.

GoBlog plugins enable completely new and optional functionality. Andrés created a plugin to show the song currently playing on his blog. I use this plugin for now as well. 🎶 If you don’t see a song in the header, I’m probably not listening to music right now. 😅

For performance reasons, the plugin will fetch the currently playing song from Last.fm every five minutes and display it if the song was played no more than 10 minutes ago.

ChatGPT is smart enough to detect what the code in the single minified JavaScript file on my blog front page does. Try it out! 🙃

Ok, it’s also not that complicated to guess by looking at the long string at the beginning… But ChatGPT has figured out what it’s called.
