TWiR quote of the week

imagine a From<[u8]> for SHA-512, rust automatically impls a quantum computer to find all inputs that result in that hash :^)

seri in #beginners on official discord server.

Context: the OP in the question confused the complementary auto traits (from & into) and thought that From<T> for U automatically implements Into<T> for U instead of Into<U> for T


In response to community flagging this post as 'inappropriate', I've decided to withdraw this post.

However, to give context to @ZiCog's reply below, and for historical records, I'm keeping the link to Twitter where original quote can be found.

I don't think talking of variety of often erotic practices or roleplaying involving bondage, discipline, dominance and submission, sadomasochism, and other related interpersonal dynamics.

is appropriate for a family friendly technical forum.


The original poster probably just meant that learning to program in Rust can seem to be an exercise in masochism.


i never knew the compiler was a furry

In response to What to say to a C programmer when they say


@ZiCog: Does anyone have a 'no holds barred, unsafe or not' solution to the problem in Rust that can match C?
@kornel: Pipe the C version through c2rust :slight_smile:
@ZiCog: Yay! Rust now beats both Clang and GCC!


Generic types describe ranges of types, just like types describe ranges of values, and traits are to generic types what properties are to structs. So a new trait actually defines a new type of types, and can be combined with other traits to form a hierarchy of traits.

But I know one thing: I certainly wouldn't implement a new version control tool in Python 3 and I would probably choose Rust as an implementation language for most new projects in the systems level space or with an expected shelf life of 10+ years

At a previous job, two of us spent a full week of 8 hour days chasing down a memory error (in a C++ codebase). It took about ~2-5 hours to reproduce the random crash each time, at which point, the traces we got back were so mangled due to memory overwrites, all we could do was add printlns to slowly narrow down the problem. In the end, it was something like a pointer that wasn't nulled out correctly.

With all the times the Rust compiler screamed at me so far, I don't think it has added up anywhere close to 80 hours yet. And that was just one bug.

So either the compiler screams at you, or you end up wanting to scream at each other...

I just have to suggest it, since I'd never thought of referring to godbolt as "god".


Is it acceptable to nominate our own quotes? ...because I just stumbled upon a metaphor which I think has a shot at this.

Sure. Why not? :sweat_smile: People nominate their own crates.

In that case,

[Three paragraphs of analogy about knife-juggling]

Heck, if anyone wants to try that for a less divisive candidate for Quote of the Week, here's a more quotable formulation:

Programming is like juggling. Memory-unsafe programming is like juggling knives. Proper use of the unsafe keyword is forcing audience members to climb onto the stage in full view of the juggler before they get into range of the knives.

...and another one I just found which is particularly insightful:

I think this is another story about the destructive power of the internet echo chamber, where the asymmetry of one person vs. a mob of people who are in reality probably not all that engaged with the problem but nevertheless have enough engagement to send a nastygram or two creates a distributed denial of decorum attack that no single human being should be expected to deal with "nicely". Our ancient instinctive tribal signals of whether or not you are approved by the tribe, tuned for tribes of 150 people or so, receive a message that 15,000% of the tribe thinks you are a bad person, and our natural human response to that is a lot of stress at best (our ancient instincts tell us that eviction from the tribe is a bad thing , even though in practical terms eviction from this particular tribe won't be much of a problem at all in the modern world).

Especially the term "distributed denial of decorum attack".

(I'll try my hardest to make that my last submission this week. I went from a pre-actix-hullabaloo quote, to something of my own post-actix, to something of someone else's post-actix in such a short period of time, and the two "something of someone else's" ones are so different in what their focus is.)


This reminds me of juggling razor blades in C++ (lock free programming)
