We got tired of tools that only check if code runs. So we built one that argues back. 🦀 Real Rust challenges, real reasoning on https://rust-skill.com
Thank you! 🙏🏼

Today is an very special day for us.
After a lot of hard work and failed attempts, we got our 1st paying customer 🥳
This is EVERYTHING to us and we're buzzing to see the hard work and evolving with 100+ devs feedback, pay off!
#buildinpublic #rustlang #learnrust #devtools
Very big day for us :)
First paying customer, many to come
#buildinpublic #rustlang #learnrust
Day 27/30 building @rustskill.bsky.social
Revamped the llm to be more concise in its questioning.
#buildinpublic #saas
Appreciate it, legend!
We aren’t stopping anytime soon 😎
Night!
Please do let me know how it feels!
We’ve evolved like crazy since we first reached out to you tbf.
Updated landing
Updated the LLM (heavily)
Interface got a full redesign
Interface UX redesigned too
Hahahahah *obvious product plug incoming*
If you use our platform…………. maybe it’ll become true? 👀
funniest reply we’ve seen this year 😂

Finished the mvp of the rag build. Professor crab now recommends learning materials in our knowledge base based off of gaps in the users knowledge.

How it started vs. how it's going 😏🦀

MASSIVE change in our MVP
We’re listening to your valuable feedback!
Pushing update soon -> rust-skill.com
Week 1 of MVP launch wrapped up!
> Ads running at a 1% CTR (decent!)
> 65 🦀 developer sign-ups (solid!)
> Only 50% of signups actually tried a challenge (🚨🔴)
Users who did try it, loved it. We must have a UX issue of directing signups to their first free challenge.
We're pushing an update! LFG
They want structure, not scripts.
If you can reason through a new problem with calm, you’re already top percentile.
And if you want to practice that skill, not syntax drills, but real reasoning, that’s what I built RustSkill for.
🦀 Real challenges. Real feedback. Real growth.

Good engineers think in ownership.
Who owns the data? Who borrows it? When does it end?
That mindset is why so many Rust devs crush interviews.
The compiler trains your brain to be responsible.
Most interview questions are secret design challenges.
They reveal how you organize complexity, not how fast you can import a library.
They want reasoning, not reflexes.
Slow down, restate the problem, and show that you think before typing.
Everyone says big tech interviews are about speed.
They’re not.
They’re testing how clearly you think, how calmly you reason, and how well you explain your choices under pressure.
Here’s what they’re really assessing 👇
You should give us a try! You won’t regret it :)

Daily challenges that test your logic, not only syntax
#rustlang #learnrust #devtools #buildinpublic
That’s the whole idea behind #RustSkill.
Not syntax drills, but reasoning practice.

These lessons compound in #rustdev:
> Cleaner APIs
> Safer concurrency
> Fewer assumptions
> Better architecture
Rust doesn’t just teach syntax.
It rewires how you think about systems.
Most languages let you fail at runtime and patch later.
Rust forces you to prove safety first.
You start spotting bugs before they ever exist, in Rust or anywhere else.
You stop thinking in variables and start thinking in responsibility:
> Who owns this data?
> Who borrows it?
> When does it end?
It’s not just memory safety.
It’s mental clarity.
#rustacean #rustprogramming
Other languages let you wing it.
#Rust makes you stop and think.
Every compile error is a small code review from the compiler.
You learn to reason before you run.
Everyone says #rustlang is hard. It is.
But not for the reasons you think.
The syntax isn’t the problem, your thinking is.
Rust quietly forces you to reason like a systems engineer.

Quiet precision, fewer surprises, and more trust in the language.
That’s the spirit we’re building on.
Rust 1.91.0 isn’t trying to impress you.
We are, though.
If you’d rather sharpen reasoning than memorize syntax, check out rust-skill.com
🦀 Practice challenges, lifetime puzzles, and real AI feedback.
Quiet upgrades that make life easier:
PathBuf::add_extension
Duration::from_mins, from_hours
BTreeMap::extract_if
Easier equality between Path, String, and &str
Small things that remove daily friction.
PathBuf::new and TypeId::of now work in const contexts.
More logic runs before your program runs, giving stronger guarantees and less uncertainty.
