Hey #rustlang friends, what are your feelings on the visitor pattern?
Any big caveats? Heavy dependence on a specific use case?
Anything you'd always use over picking the visitor pattern?

I'm sure you have amazing AI. Let me know when it transcribes my name accurately.
That's going to be my "oh crap, we're screwed".

So much nice stuff in rust 1.89 blog.rust-lang.org/2025/08/07/R...
My favourite has to be the stabilisation of `Result::flatten` but hard to pick from such a nice set of changes:
- File::lock / lock_shared / try_lock / try_lock_shared / unlock
- Explicitly inferred arguments to const generics

We're getting to that stage where the only post about a new AI model that will impress me, will be one where they'll announce it was fully coded by the previous model.
That will be the flex to end all flexes.

What gets you, a Senior engineer to punch through the ceiling of "Senior"?
✅ Technical leadership thinking beyond the current project
✅ Being a multiplier everywhere
✅ Grace under pressure when problems arise
✅ Company > Function > Team > Individual
✅ Setting the example

When I get the right data structures and the (roughly) right design, `rust` is beyond spectacular.
Renaming, reorganising, restructuring, adjusting business logic, etc, it all just comes so easy. No other language I know does this so well.
I don't think there's enough writing on this honestly.

Whenever I have to discuss with engineers that they shouldn't fear keeping to the scope, or even reducing scope, I do this one simple trick.
I ask them to go to Chrome and search for a word.
Then I ask them to do a case sensitive search.

I don't know how else to say it: Gemini CLI is incredibly disappointing.
I can't go a few uses without getting a loop and halting.

Nothing like taking an hour every few months and cleanup your editor config.
Software and tools and their config changes all the time and I love spending time once every 6 months or so reviewing what I have vs what I should have.
