@ekuber I just missed the fn keyword and found that the error message in that case wasn't so helpful.

error: expected one of ! or ::, found (

I couldn't find a issue for this, but I thought I'd check with you before creating one.

I came across this article the other day, titled “Why Rust cannot replace C++”.

I feel that the author completely fails to understand the opposing argument. The article claims that with “new” C++ features like smart pointers, you can write safe code in C++, therefore Rust is unnecessary.

But I don’t want a language where I can write safe code, I want a language where I must write safe code.

Sure, it’s much easier to pass pointers (*, &, or shared_ptr) around, but now I have the “cognitive overhead” of ensuring that it’s only accessed from one thread at a time. Or not used after it’s been freed in the former cases.

When I’m working with the borrow checker that is something that I don’t have to think about. It’s less “cognitive overhead”.

There’s this common statement that “the cognitive overhead of working with the borrow checker just isn’t worth the security benefits when you can write safe code in other languages”.

But the comparison is always to the “cognitive overhead” of writing something in some other language. When the comparison should be to writing something correctly in some other language.

@mgeisler that’s a bit my point. A style guide is useful if you have the time and ability to train people on it, but if checking compliance is something a human has to do then you’ve still got cognitive overhead and humans, of course, get things wrong sometimes.

I wrote a blog post on performance optimization using (cargo) flamegraph for profiling and Divan for benchmarking.

This was a real case of a real algorithm which needed real optimization!

@ekuber @rust @weiznich this new class of attributes looks so promising!

(I mean, on_uninplemented looks great already, but the possibilities…)

We are not bowing down to our digital masters, I promise!

Today I learned about Margin collapsing and excuse me but what the fuck? https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_box_model/Mastering_margin_collapsing

hds,
@hds@hachyderm.io avatar

@fasterthanlime I thought this was the main difference between margins and padding (because aside from this you can add/remove ancesters and change where you put the margin/padding to use one or the other).

If I want to be completely honest about , what disadvantages should I be listing. So far I have:

  • Compile times
  • Language complexity (compared to…)
  • Churn
  • Best practices
  • Recommended dependencies

What else?

hds,
@hds@hachyderm.io avatar

@ekuber yeah, that’s very true.

It’s Friday, I’m not fighting the borrow checker, we’re discussing our difference of opinion over a beer.

Have you had experience, successful or otherwise, promoting within your company? Especially to other teams and departments once you’ve started using it in your own team?

I would love to hear what you think went well and what you would have done differently in hindsight.

Comments in replies and boost for visibility please! 🦀

@hyde @mre Yes! I do listen to that one (and have probably already "borrowed' some ideas)!

Thanks for the suggestion!

poll: when you have a merge conflict, how do you prefer to handle it?

@b0rk @hazelweakly (edit weird text file) except for the Xcode project file, that beast is unmergeable.

Or at least it used to be when I was doing macOS / iOS dev 7-8 years ago.

One of my large corp clients ($10b+ market cap) is insisting on 45 day payment terms and I can safely say this doesn't spark joy.

@hds@hachyderm.io avatar

@timClicks the medium sized retailer and publisher I worked for in London had 30 day payment terms when I moved from employee to freelance, so the extra 15 days doesn’t seem too bad for such a monster… 🤷‍♀️

@Vyothric @foone I loved this game when I was younger, I think it was pretty new when I played it (but you could never be sure with shareware games in Australia when you didn’t use the internet).

Tomorrow is Rust for Lunch! A lunch time virtual meet-up. We’ve got two talks from 12:00-13:00 UTC.

@molly0xfff @vampiress looks like I need a new RSS reader. There are some suggestions in this thread that I’ll try, but if anyone else has recommendations, I’d be happy to hear them.
