TWiR quote of the week

There's a constant focus on backward compatibility, but the (equally constant) feature creep will inevitably break it. English hasn't moved from version 3.x for centuries, and we still have multiple redefined keywords, many modern compilers have dropped support for outdated constructs which -- though legal -- haven't been in use for ages, and in fact the very language has several different implementations with varying levels of mutual compatibility.

-- Birion as one of several fun replies to "The only consistent conclusion is that English is a weird language that needs a significant overhaul." @

So I think this is what many Rust developers means when they say zero trust cost abstractions.

Please do not publish this one, (EDIT2: I don't think it's worth publishing) I just fond the slip of the tongue very funny!

EDIT: this post has been flagged as off-topic. I would have like to know why. This is a citation, about Rust, from a very interesting conference, and I selected it because it was funny. And while I think its not worth publishing it in TWIR because it doesn’t bring any new insight about Rust, I think it has its place in this thread for the pleasure of people that propose and vote for TWIR citations.


This thread is for submitting Quotes of the Week for This Week in Rust. If you don’t want your quote to be published, then it probably doesn’t belong here (though TWiR quotes that are just funny have been published before).


By no means a "learning" kind of quote, but…

I just discovered an absolutely critical bug in the Rust logo:

It's not symmetrical! The inner and outer circle of the gear don't even have the same center.

(yes, this has somehow gone years without anyone noticing)


Oh come on, I was just about to go to sleep...



(The elision there is to avoid making any commentary on the actual issue in that topic part of the quote; in general, I think we should avoid highlighting quotes that directly comment on one side of an active topic, so I left that part out.)


I’m saddened to think that because this industry has an obsession with making programming accessible to the lowest common denominator, expressive and innovative languages like Rust will fall by the wayside, and we’ll all be writing code in languages like Go and Python in the future because they’re “easy” and even high schoolers can learn them in a couple days.

A nice reminder that sometimes the shortest answer isn't the best one.


Fun fact if you repeat "Thread scoped private field injection" 3 times to a Mirror you will summon a demon.

For any language SomeLang™:

The context of that thread is already interesting on its own, but I even think that taking that quote seriously / in a first degree fashion is actually meaningful: for some codebases written from scratch and which developed features out of an initially thin core, the newly obtained perspective on the problem ought to make rewriting that codebase "from scratch" yield cleaner, leaner, and potentially faster code (and back to that RiiR thread, hence why sometimes the Ri part may be just as important if not more important than the iR part).



The error message code will at one point become sentient and decide to send a robot back in time to save mankind from skynet [...]

I performed an extremely scientific poll on twitter, and determined this is not how it's pronounced

Well, it really is Vec<T, A>, pronounced Veck-tah. :stuck_out_tongue:

Look, I moved away from Boston to avoid this sort of thing :laughing:.

"For me, the joy of Rust comes from the fact that I can write code that represents the mental model I have of the problem" - Jon Gjengset, 2022-01-01 Q&A/AMA/Whatchamacallit.

I resonated so strong with this statement. This is the reason why I find joy in Rust and I evangelize about it.


I see a lot of “we rewrote X in Rust and it got faster” posts. I think that if you rewrite anything from scratch with performance in mind, you’ll see a significant performance improvement. I’m suspicious of how much Rust itself is needed versus the developers having some performance discipline.

So why aren't we all fuzzing security-sensitive surfaces, at least for a modest number of cycles? Well that comes down to the difference between apes and programmers: apes know when they should be using tools.
