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

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 ... message truncated ...

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.

#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. rust-lang.github.io/rust-clippy/...

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.

Glad it's Friday. Please, no more #golang next week. `go vet`, codeql, `go race`, `golangci-lint`, oh my! So many things to check. What am I missing? To be fair, in #rustlang you have to do `cargo fmt -- check` and `cargo clippy`

s/getting used to/tolerating/ I have done plenty of #golang when I was at Uber. Now that I've tasted the #rustlang sauce it's so painful to go back. In golang, changing the visibility of a function means that EVERY caller now has to be changed. I won't be getting used to that.

050

Ron Kuris ✅ @svjaneo.com · 30/05/2025

Yep. Foo() is global but foo() is not, so changing the case of the first letter changes its visibility.

Ron Kuris ✅ @svjaneo.com · 30/05/2025

Writing some #golang code today. Feels so painful. Renaming a function to change it's visibility feels so wrong.

I know, I wasn't making it a debate. I just don't see why it's easier to translate from 'loop' to 'for', than it is going from 'for' to 'loop'. I don't get why it's about the number of keywords. A pattern is a pattern, which needs to be learned by the LLM, unless I am missing something.

Ron Kuris ✅ @svjaneo.com · 19/05/2025

Super insightful response. The memory model rust wants you to use is actually also friendly to the garbage collector as well

020

Ron Kuris ✅ @svjaneo.com · 19/05/2025

I am not sure if I understand. For example, "for" in #golang translates to either "loop" or "while" or "for" or an iterator in #rustlang. I think fewer keywords doesn't mean easier anything. You have to learn each variety of "for" instead of four different words.

Do they use sexadecimal?

010

Ron Kuris ✅ @svjaneo.com · 18/05/2025

Cursor's ability to rewrite from #rustlang to #golang seems better than the other way around. I wonder if it's because there are fewer examples of good rust code than go for the LLM.

Presumably you've never worked with Java, with some error messages (novels) that push vim to its limits.

One of the things that is medium level annoying in Rust is that sometimes it fails to communicate to you how easy your problems are if you just used that other method that also exists. I didn't programm in this language for a few months, forgot everything about file ops and there were far too many

Learning #rustlang combinators was a slow process. Coworker reminded me of learning the subtle differences between things like `unwrap_or` and `unwrap_or_else`. While these are well documented, there's some cognitive load and learnings in languages other than #golang.
