Fintech Engineering Handbook

I just published Fintech Engineering Handbook distilled from 6 years of tears, sweat and swears.

It’s a free ~25-page resource with various hints and patterns around handling money in software systems.

Tell me what you think!

I've built a small app to engage with my kids more and easier

My kids quite often ask "what do we do now?" and I sometimes struggle to find an activity for them. Sure, they have plenty of games and toys, but it doesn't help for some reason. So I've built a small web/mobile app to help myself and maybe others.

  • It comes with quite a few activities to pick from
    • Classic 2-player activities: memory, battleships, tic-tac-toe, chess, checkers, hangman etc.
    • Car-friendly ones for long trips: word associations, 20 questions, last letter, etc.
    • Basic learning help for reading and arithmetic
    • List of classic books to read together
    • Some single player ones as a bonus: minesweeper, solitaire, sudoku
  • It makes offline play a first class citizen: printable sheets, rules, etc. to minimize screen time.
  • It’s completely local, no server, no accounts, etc. Is also completely free and open source.

Happy to get some feedback! I'm curious if I'm the only one with that problem and if anyone else finds it useful.
It has activities suitable for 4-6 yo, because that's the age of my kids, but I think it might be applicable to a wider range.

I'm considering adding "custom activities" so you can add your own stuff, but syncing it between devices would be tricky...

Tandu.app - a small scala.js app to engage with your kids more

I’ve built a small app to engage with your kids more and easier. It's built entirely in scala.js and available on GitHub. That being said, the stack is pretty boring - it's Laminar + vite and almost nothing more.

In case you're interested in the "product" side of things:

  • It comes with quite a few activities to pick from
    • Classic 2-player games: memory, battleships, tic-tac-toe, chess, checkers, hangman etc.
    • Car-friendly ones for long trips: word associations, 20 questions, last letter etc.
    • Learning activities for reading and arithmetic
    • List of classic books to read together
    • Some single player ones as a bonus: minesweeper, solitaire, sudoku
  • It makes offline play a first class citizen: printable sheets, rules, etc
  • It’s completely local, no server, no accounts, etc. And OSS, as I mentioned before

Happy to get some feedback!
