Hello World magazine features HaHaKeys

08 September 2026

Cover of issue 30 of Hello World Magazine, showing a focus on critical thinking in the age of A.I. The new issue of Hello World magazine for educators in computer science features an article I wrote about HaHaKeys, my joke-based typing tutor for children. The magazine is distributed free of charge in print to educators and is available for anyone to download.

The article details:

The inspiration for HaHaKeys
The development process, iterating using AI in a similar way to the technique I outlined in How to Make Money with ChatGPT
The feedback from my Code Club when we tried it in a sesssion

As I note in the article, I had reservations about using AI for development but this was the only way I could make it happen. The app creation process still required my programming and software testing knowledge, so I don't think AI is a magic wand for making apps just yet.

I continue to add jokes as I remember or hear them, so there are now 220 to amuse you as you refine your typing skills.

HaHaKeys was also featured in Primary Times magazine in May. Thanks to both publications for helping to spread the word. HaHaKeys is a free tool without advertising for anyone to use, so there's no budget for promoting it. If you know someone who might benefit please do share it with them or their parents. There's no need to register. Try it today!

I previously wrote an article for Hello World about debugging in Scratch (PDF), which also features in my free Coding Compendium ebook of Scratch, Python and Raspberry Pi tutorials.
