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.

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.

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...

#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.

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

Hire or don't hire? Gave the classic "two-sums" problem, where you try to find offsets of elements that sum up to some target value.
Here's their rust implementation, rolled out quite quickly.

Please. Same time tomorrow is not `now += hours(24)`. There are *NOT* 24 hours in every day. Some days have 23 and some have 25, assuming you live in a region where this horrible thing called Daylight Savings Time exists, which is in ~40% of all countries, affecting ~15% of the world population.

Back from Avalanche Summit in London! So happy to present my project. Ran into a few #rustlang enthusiasts as well. Of course, the perf numbers tell the story for me.

Super insightful response. The memory model rust wants you to use is actually also friendly to the garbage collector as well
Rust has a much more restrictive memory management model
rewriting in Go is usually just trivial syntactic transformation, while rewriting in Rust often requires rearchitecturing code and thinking about ownership.
generally, GC makes code easier to write at the cost of runtime performance.
