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.

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.

zuzuleinen··on The revenge of the philosophy majors
Do you remember the title of the book on principles of hermeneutics?
zuzuleinen··on Doing nothing at work
"The more difficult it becomes to remain silent, the more likely it is that silence is the correct action."

Love this!

zuzuleinen··on Ask HN: What are tools you have made for yourself since the advent of AI?
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.

zuzuleinen··on Ask HN: What are you working on? (May 2026)
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...

zuzuleinen··on Three constraints before I build anything
Thank you for this piece! I never thought consciously about creativity unlocked by constraints.
zuzuleinen··on Show HN: Algotutor – Practice Go with spaced repetition in your AI agent
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!

zuzuleinen··on Do I Stop Learning Coding? DSA?
"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.

zuzuleinen··on As a developer, my most important tools are a pen and a notebook
I like to have an Obsidian vault for every company I work for.

But when I really need to think I upgrade to pen and paper.

zuzuleinen··on As a programmer, get your math sorted
Is this related to csprimer.com?
zuzuleinen··on Open Source Society University – Path to a free self-taught education in CS
I think https://csprimer.com/courses/ is a good fit if you also want community. I think Oz Nova who is behind csprimer was one of the authors of teach yourselfcs
zuzuleinen··on Career Advice in 2025
I highly recommend csprimer for this.

Or if you want to just use books go with:

zuzuleinen··on Common Interface Mistakes in Go
Thanks for your comment! On the golang sub-reddit[1] was not that well received. I knew it will lead to that because some things are controversial and also on my part I should have probably explained more so I tried to do that in the comments there. It's hard to condense lots of info in one post, but I just wanted to write about these things cause I see them so often

Are you interested in a particular method? I might consider it
zuzuleinen··on Software freelancers, how did you land your 1st, 2nd, and Nth jobs?
I don't search for "people with a problem needing solving" on Linkedin. I look for companies that allow remote work on a B2B contract. Usually, you can filter for remote work
zuzuleinen··on Software freelancers, how did you land your 1st, 2nd, and Nth jobs?
When I moved back from Germany to my country I continued working for my employee charging them hourly rate. I didn't considered myself a freelancer then, but after I quit that company 2 years later I continued with B2B for companies outside of my county.

Now I try to find freelance jobs using Linkedin mainly.
