That was a delicious waffle today on my after-work walk. 🧇

Blog reactions

Published on in 💭 Thoughts

My girlfriend gave me the idea the other day, when I complained that sometimes I don’t know what to blog about, that I could “react” to my old posts. Kind of like how web video producers react to videos.

A solution for social media?

Published on in ✍️ Posts

Sometimes I find it quite interesting to read through articles that I wrote three or four years ago, back then still on the platform Medium. Some time ago I deleted them on Medium and published them on my blog in a “Medium Archive”.

Like Horst Gutmann I exit the Advent of Code challenge.

Yesterday I wrote about a new “blog feature” showing below a post places on this blog where the post was mentioned. Unfortunately this has a high complexity and is not very fast. Today I tried (and managed) to improve the algorithm so that the complexity is just O(n). However, the code does not work as I expected it to, because Hugo does not provide a way to use global variables.

World map of domains

Published on in 🔗 Links

British domain registry Nominet created a world map of country-code top-level domains. It’s really interesting to see that .tk (Tokelau) is is the world’s largest ccTLD, because registration is free and no expired domains get deleted. After that comes .cn (China) and .de (Germany).

Today I took the chance, as long as it is still possible to leave the house, and used the good weather to run a little. Only 4.5 km and not very fast, because my fitness is on a pretty low level at the moment. But I realized how important this exercise is, especially at a time when you only leave the house to go grocery shopping. Running in particular is an uncritical way to do sports. You can do it alone and you can keep enough distance from other people. And one advantage: it can be really challenging.

I migrated from a self-hosted mailcow-dockerized to the hosted version of Mailcow. It’s just because I don’t want to care about keeping everything up-to-date, secure and backup-ed. Now I have some stricter limits, but in the past I didn’t reach that limits and I doubt I will reach them ever. To migrate all emails, I used the online version of imapsync.

I’m always amazed when I do my usual web surfing and suddenly discover a link to my own blog, website or one of my projects from sites I never visited or heard of before. 😄
