Not a direct answer but the guys at Exercism (non-profit that publishes really good and free programming language self-study courses) recently launched a separate site to teach junior programmers both vibe coding and software engineering fundamentals.

Learn data structures and algorithms through interactive visualizations and interview prep tools.

Check out what I just built with Lovable!

Free AI tutor for kids aged 7-9 that personalizes lessons in coding and technology through interactive games.
u/Designer_Process_715 · Reddit
I built a free AI tutor for kids that remembers each kid and makes learning feel like a game I'm a software engineer and dad of three. My two older kids were deep in YouTube Shorts and Roblox, and I didn't mind the screen — I minded that they walked away with nothing. So over the last ~7 months I built the thing I wished existed. It's called Aivie Spark. My favorite moment testing it: my son hit a Boss Challenge on a math topic and got stuck. Instead of giving up — or getting the answer

An AI-powered platform for solving and collaborating on math problems in a social context.

Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.

Practice coding interviews, system design, and code review with an AI coach instead of a judge.

Daily coding challenges to keep developer skills sharp with AI assistance and streak tracking.
u/Administrative_Egg78 · Reddit
I built this because AI was making me a dumb&lazy engineer I noticed something sad about how I use AI. I was shipping faster, but practicing less. I could get answers quickly, but I was losing the habit of working through the fundamentals myself. So I built Unrot: short daily challenges for developers across languages, system design, architecture, data engineering, and other tracks. Game/xp and rewards system, a tiny bit competitive. No signup required to try it: https://unrot.dev

Block distracting websites by solving math or coding puzzles.

TLDR built a Chrome site blocker that lets you into distracting sites only after you do some math or simple coding (JS only right now). Direct link to extension (the site just gives you more context): https://chromewebstore.google.com/detail/sphinx-earn-your-di... Philosophically it's a speed bump rather than a hard gate, because you'll eventually tear a gate down but you'll leave a speed bump. I've always eventually removed site blockers, or just had them become a nuisance that I reflexively dismiss before getting to distracting sites. Site blockers don't really reduce the "start navigating to a distracting site" muscle memory, and they eventually just become annoying. Dopamine is a hell of a drug. At the same time, I've been getting frustrated that my intermediate/advanced math skills have atrophied, and becoming more senior in my career (plus AI...) has caused my coding skills to atrophy even further. Realistically I'm not going to force myself to do math or coding exercises aft
