AI Translation Evaluated: Effort and Risks

In march 2025 I decided to try LLM translation from German to English. I had given the original article to others via Google translate many times, and I had been asked to evaluate AI tools, so I decided to give ChatGPT a try for translating moderately complex text. It took about two hours of work over several days to fix up the translated article so it actually says what the original says, with corrections for a lot of subtle mistakes that corrupted even the core message. This article follows the process and evaluates the risks.

Je mehr ich über die Situation im Nahen Osten gelernt habe, desto unsicherer bin ich geworden, was die richtige Vorgehensweise ist. Jede einfach wirkende Antwort zerbricht.

Unicode pictograms to mark progressively rising values

For Ace Maths I searched for unicode icons to mark progression: show that you’re getting better. Since I found a lot of different options (from simple sparklines to a huge list of animals), I’m collecting them in this article.
