Getting super excited as #firewood is finally getting integrated into #avalanche #avax. That plus doing some serious vibecoding with #github-copilot #github to smooth out the remaining tasks!

#github-copilot is the shit. I love being able to steer AI while it's working.

Documentation being worked on via #github-copilot for #firewood with assistance from the @github.com next team....

Pre release stuff!!!

TIL "immutable variable" is a contradiction. "variable" means it can change, and "immutable" means it can't.

Did you find a rare labubu?

Ron Kuris ✅ @svjaneo.com · Sep 22

In #rustlang it's `use tylenol`. No point importing, just use it.

Probably an off-by-10 error. Did you compute this in C++?

Until you realize that if you extract raw pointers or iterators from a std::vector and then modify the vector in a way that causes reallocation, those pointers or iterators can become dangling, which is UB.

Or when you realize std::vector isn't actually thread safe.

Or

I made it through the wilderness
Somehow I made it through
Didn't know how lost I was
Until I found #rustlang

I was beat, incomplete
I've been had, I was sad and blue
But #rust made me feel
Yeah, #rust made me feel
Shiny and new

I recommend enhancing go's panic on nil pointer message:

panic: runtime error: nil pointer dereferences can be avoided in #rustlang, but not #golang, and this code dereferenced one at runtime and the code didn't bother to check, and the reviewer didn't catch it either. Use a better language.

TIL about i64::div_euclid. So many ways to do math in rust.

The 64-bit signed integer type.

I wonder if it just said "ITER" if it would be even more esoteric

I need to make this bumper sticker! Any suggestions for an online site to do it?

The next person who tells me rust is too verbose will get this post.

TIL that in #javascript, parseInt(0.0000005) results in 5.

Here's the equivalent in rust. Definitely too verbose. play.rust-lang.org?version=stab...

rust program that does what javascript does in one line

#rustlang discourages basic math -- addition, subtraction, etc!

Why is that? Because off-by-one errors and overflow errors are a major source of bugs. Enable this lint and use checked operations instead of just raw math.

#rustlang iterators are so amazing. Do you know what an ExactSizeIterator is and a FusedIterator?

You sure you want a tamale and not a taco? Also maybe a calzone is a better choice. Thank you cuberule.com

Identify your food based on the location of structural starch. Is a hot dog a sandwich? No, it's clearly a taco.

Are you planning on cross-posting to reddit each time? If so, I'll unfollow here and catch you via the reddit post.

Just like a junior engineer, AI is really bad at rust error handling.
