As a daily user of Anki and Math Academy, I'm very excited about how software can help us learn.

Now, with AI, we can really build tools that were not possible before. I built for myself AlgoTutor[1], a CLI tool that teaches Go developers algorithmic skills and concurrency.

The recent Understanding floating point[2] from Oz Nova is also a type of tutorial I want to see more often.

Massive thank you for the introduction to Math Academy. After a quick look I signed up and it is fantastic - exactly what I wanted.

I'll take a look at AlgoTutor in the future :)

Math Academy is doing it right. Their neat synthesis of spaced repetition and the knowledge DAG is slick, but honestly the extremely fine-grained skill decomposition is what’s missing in virtually all of higher education. I’m trying to follow MA’s example as I put together curricula for my undergraduate CS courses.

I'd never heard of Math Academy. It seems interesting, but quite expensive ($49/month for software which is in beta). Would you say it's significantly superior to something like Khan Academy (which is free) to justify paying that much?

It is indeed expensive, especially considering my current location(Romania).

I have a rule of doing 20 XP per day, and I kept that rule for more than half a year. Maybe the price is also a factor, but I never managed to keep that pace for Khan Academy when I tried it. You can check their current courses here: https://www.mathacademy.com/courses

I think the topics and curriculum are more serious, and I would definitely recommend it if you have kids or are in highschool/uni. I'm 37 now and only do it to keep my brain sharp and build my mathematical intuition and I think is great for that due to its focus on practice and spaced reviews.

I think they have a 1-month trial, and you get your money back if you cancel within 30 days if you want to try it.

I tried Math academy twice and I cannot understand the hype but a lot of people seem to love it so maybe it's just not my style of learning. Each topic seemed to contain too little information to actually grasp it. It was like

Trig 1 -> This is a triangle and trig is about triangles.

Quiz 1: blah

Yes if you can afford it, then it's absolutely worth it. Nothing better at the moment.

This review lays out how you should think about the costs and benefits: https://jonathanwhitmore.com/posts/2024-09-10-mathacademy/in...

It is vastly superior to Khan. Had my kids go through both, so can compare.

That said, on higher levels there's some cruft that trains mechanical skills, and that's on subjects that are needed only in the scope of the US system. For Europeans these should be optional, alas they are not and this adds a lot of tedium and hassle to an otherwise rather frictionless process.

If you spend 30 mins/day studying math then that's $3.30 per hour.

If it improves your learning efficiency by just 10% then it's worth it.

(My son uses math academy 3-5 hours per week.)

Do you remember the title of the book on principles of hermeneutics?

"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.
