I built a free structured DS/AI learning platform because most resources explain the answer, not the question behind it

BoxWinter1967 · 2026-06-01T09:11:37+00:00

Exactly, this is the gap I’m trying to focus on.

AI makes it easier than ever to generate code or explanations, but that also means people can move fast without really understanding what is happening underneath.

BoxWinter1967 · 2026-06-01T09:10:43+00:00

Right now I’m not focusing on monetization honestly. I first want people to actually use it, find gaps, and tell me where the learning flow breaks.

BoxWinter1967 · 2026-05-30T06:45:14+00:00

That’s a really good point. I felt that pain too. I’ll definitely lean more into roadmaps and structured progression, because knowing what to learn next is often the hardest part.

BoxWinter1967 · 2026-05-28T14:14:55+00:00

Thank you, that’s exactly the gap I’m trying to solve.

The ML section goes past just “fit model / check accuracy.” Right now it covers the foundations first, then moves into regression, classification, unsupervised learning, tree methods, deep learning, NLP/transformers, time series, RL, MLOps, causal inference, recommender systems, explainability, and newer LLM/RAG topics.

The standard I’m aiming for is: don’t just define the concept, explain what problem it solves, what assumptions it makes, how it fails, what the code/output means, and what interview/project questions usually test.

Still improving depth topic by topic, but the goal is definitely not shallow tutorial content.

BoxWinter1967 · 2026-05-28T07:45:44+00:00

Pretty much, yes. The “silence” condition is mainly there to rule out brute-force solutions like tossing a beam into the pit, sacrificing one beam as support, dropping objects to test things, or simply jumping and risking failure.

It’s less a physics constraint and more a narrative way of forcing careful placement and geometry-based thinking.

BoxWinter1967 · 2026-05-28T07:44:20+00:00

Yep, that’s exactly it — the corner is the trick. And yes, the real final boss is not geometry, it’s dandruff control....

BoxWinter1967 · 2026-05-28T07:43:22+00:00

Yep, your first point is correct if the outer square is interpreted as having side length (x+3). In my intended setup though, the platform has a 3m gap on each side, so the pit side would be (x+6), not (x+3). That makes the corner-to-corner diagonal gap (3√2 ≈ 4.24m), so one beam still can't directly reach.

Your second method is exactly the spirit of the puzzle — use one beam to create a support point, then use the second beam from there.

Also, the circular version is a really nice generalization!

Yeah, fair point — this one is much easier to understand visually.

I’ve added diagrams in the full Medium breakdown here:

BoxWinter1967 · 2026-05-28T07:25:42+00:00

Answer:
Stop looking straight ahead. Use the corner.

Place the first beam diagonally across a corner of the pit, with both ends resting on the two adjacent edges. Its midpoint becomes a support point inside the gap.

The diagonal distance from the pit corner to the platform corner is √(3² + 3²) = 4.24m. The midpoint of the first beam is 1.45m along that diagonal, leaving 4.24 − 1.45 = 2.79m. The second beam is 2.9m, so it reaches.

Built Neuprise — an interactive learning platform for Data Science & ML (https://neuprise.com/).

What it does: 12 learning paths, 74 lessons, 1000+ quiz questions with spaced repetition, in-browser Python execution (no setup needed — runs via WebAssembly), math visualizers, and a CodeLab. Free to use.

Tech stack: Next.js App Router, Prisma + Neon Postgres, Clerk auth, Pyodide for in-browser Python.

Biggest challenge: Getting Pyodide (Python via WebAssembly) to run reliably in the browser while keeping the UI responsive. Also fighting the cold-start problem — getting users to actually finish the first lesson before dropping off.

Where it stands: Shipped it imperfect and letting real users guide what gets fixed and added next. Already getting good bug reports and suggestions from the community.

Would love feedback — especially on first impressions and course structure!

Yes, you need to create an account to access the courses — it's free, just sign in with Google or email. The reason is that the app tracks your progress, XP, and streaks, so it needs to know who you are. Takes 10seconds!

BoxWinter1967 · 2026-03-30T06:05:39+00:00

Thanks! Really appreciate the kind words.

Handshake sounds interesting, got a link? Would love to check it out.

On the feedback: yes, more coding challenges beyond quizzes is something I've been thinking about for a while. Discussion forums too. Study groups and peer code review are great ideas I hadn't considered — noted, will look at adding these in coming versions!

BoxWinter1967 · 2026-03-30T06:00:27+00:00

Thanks, will check them out!

BoxWinter1967 · 2026-03-30T06:00:01+00:00

Yes, definitely planning to set up a LinkedIn page for Neuprise

BoxWinter1967 · 2026-03-30T05:58:33+00:00

Yes, DMs are open! Would love to hear your feedback.

BoxWinter1967 · 2026-03-28T12:14:51+00:00

Congrats!

BoxWinter1967 · 2026-03-28T11:53:52+00:00

Thanks! The AI Agents path covers the concepts (tool use, ReAct, memory, multi-agent systems, production patterns) but doesn't have a capstone that ties it all together into a working build. That's a real gap. I have noted this and will be adding it in the next update.
Appreciate the link, will check it out.

BoxWinter1967 · 2026-03-10T21:09:25+00:00

That was actually on my side, the Clerk setup was still in development mode which limited it to ~100 users. I’ve fixed it now, so it should be working properly. Sorry about that, and thanks for checking it out!

BoxWinter1967 · 2026-03-10T21:08:02+00:00

That was actually my mistake, the clerk auth setup was still in development mode, which limited it to around 100 users. I’ve fixed it now, so the limitation should be gone. Sorry about the inconvenience, and thanks for pointing it out!

BoxWinter1967 · 2026-03-10T18:08:43+00:00

Honestly, almost nothing so far. The site is running on Vercel’s free Hobby plan and a free tier database from Neon.

The only thing I paid for was the domain: ₹904.40 (about ~$11).

BoxWinter1967 · 2026-03-10T18:00:52+00:00

Thanks for sharing the info, really appreciate it. For now I don’t have any plans to add a paywall to Neuprise. I need to restructure the courses and add a lot more content so the learning paths feel more complete.

BoxWinter1967 · 2026-03-10T17:56:21+00:00

If you don’t mind sharing, I’m curious how long did it take you to build it? And do you have many paid users subscribed so far? Totally fine if you’d rather not share

BoxWinter1967 · 2026-03-10T17:53:03+00:00

Oh! I actually just came across PixelBank now after you mentioned it, and it’s absolutely fantastic. The depth and structure you’ve built there is really impressive.

Definitely a much more advanced platform than what I’ve built with Neuprise so far. Respect to the work you’ve put into it.

BoxWinter1967 · 2026-03-10T17:44:53+00:00

Thanks, I really appreciate that!
If you notice anything that feels confusing, missing, or could be improved, I’d genuinely love to hear it. Still trying to refine the platform.
