"The more difficult it becomes to remain silent, the more likely it is that silence is the correct action."

Love this!

I built Algotutor

https://github.com/zuzuleinen/algotutor/

a spaced repetition system that teaches you how to solve algorithmic problems and Go concurrency. I use it daily.

An Android mobile app that sends e-mails to myself. So far private, but I use extensively throughout the day to send notes to myself.

If someone wants an invite drop me an e-mail.

Working on https://github.com/zuzuleinen/algotutor, a tool I use daily to train in algorithms and concurrency using Go.

I use it every morning for about 15 minutes. Review the cards, then 1 problem in the algorithms, 1 problem in concurrency, and I'm done.

I wrote more here about my motivations for creating it: https://medium.com/@andreiboar/algotutor-using-ai-to-actuall...

Thank you for this piece! I never thought consciously about creativity unlocked by constraints.

Hi everyone,

I built this tool for Go developers who want to get better at algorithmic problem solving or learn concurrency in Go.

I was not too happy with traditional methods, which only show you the solution straight away, so I came up with a way to leverage AI to present easier problems if the user doesn't know the answer, then gradually go back to the initial problem and add a spaced-repetition component to learning.

Explained more in a Medium post[1], but happy to answer any questions!

"How are you coping?"

I'm using AI at work; however, I still believe fundamentals are valuable.

This is why at 37 I still do every day a session of MathAcademy[1] and recently I built a tool to practice coding&algorithms[2] that I plan to do a session each day because I believe coding&math will prove useful in the future and the only way to get really good at them is to practice them in a deliberate way and also have a sort of review component built in place.

These 2 take around 1h combined each day. Will I look back in 10 years telling myself I wasted this time? Probably not, because I really enjoy doing both of them and I really like learning stuff, so at least I can look back and know I had fun learning.
