“Kurzgesagt - In a Nutshell” is a YouTube channel that explains different topics in short videos in a clear and easy to understand way. The videos are also visually works of art:

Pure CSS paintings

Published on in 🔗 Links

Ben Evans created amazing pieces of art. He “draw” a sunset, a still life and a portrait. But instead of images, he created CSS style sheets. All those images are made with just CSS. It is very impressive!

Writing a SQL database from scratch in Go

Published on in 🔗 Links

Phil Eaton wrote a really cool article. He documented how he used Go to write a rudimentary SQL database including a CLI. It is very interesting to read how commands are parsed and analyzed. The whole thing probably has no practical use (there are already countless mature database systems), but it’s still exciting. I remembered some of the math lectures in the first semester about formal languages.

Quizlet

Published on in 🔗 Links

This semester, as already mentioned, I take a Spanish course. Of course, learning languages also includes learning vocabulary. I looked for suitable apps and found Quizlet. I like the app even more than I thought. For example, I can create “learning sets” on the computer and learn from anywhere on my mobile phone. And various learning functions also ensure that I not only create virtual flashcards, but also learn the vocabulary.

Photopea: Photoshop in the browser

Published on in 🔗 Links

By chance in a Hacker News thread about “MSPaint in JavaScript” I discovered the tool Photopea. Photopea seems to be a free JavaScript-based Photoshop alternative that runs in any browser. What surprises me the most: Photopea is developed by a single person. I don’t use tools like Photoshop or Gimp very often, but I will try Photopea the next time I need to edit photos and images.

Reducing the size of Docker images

Published on in 🔗 Links
Updated on

Jérôme Petazzoni published a great article on the Ardan labs blog about reducing the size of Docker images. He compares different ways to package a binary into an image by using different base images and either dynamic or static linking. The conclusion is that although you can get really tiny images with SCRATCH, it is probably not worth it because it is more difficult to debug.

Google Fonts Analytics

Published on in 🔗 Links

Normally I don’t link to pages from Google, but the analytics of Google Fonts are quite impressive. In total, over 36 trillion fonts have been loaded from Google Fonts.
