We got tired of tools that only check if code runs.
So we built one that argues back.

It’s funny to see “Rust-skill follows you”. Wish that was the truth. 😂

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

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 👇

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.

(and why it makes you a better dev)

Rust 1.91.0 dropped recently.
Just had time to dive in and it’s quietly powerful.
No flashy headlines, just small upgrades that make Rust faster, safer, and more universal...

LLMs really suck at reading between the lines. Had to add in a bunch of specific commands to stop professor crab from doing some strange shit.

Ive been dogfooding @rustskill.bsky.social and I have to say the llm is already a very helpful tool. I have it implemented to use the Socratic method. Still needs a fair amount of improvement though as I find it still does not have very accurate questioning threads.
