Yep, Mike lost right there. Understandable, but still a loss.

But the challenge wasn't for performing four-froot-hoot, the challenge was described in text and adhered to. Mike thought he was describing four-froot-hoot, but accidentally only made the challenge about four-froot. The club rules even

Logging systems often have the specificity you're describing, with selectors for modules etc. You could expand a logging system to handle asserting. "Log the current state, which should never be Running."

It depends on the application. For some applications, a problem in an assert-less production application is easy to reproduce in an assert-ful debug build, because the relevant inputs are easy to capture and replay. The reason to not defaul

More like filling them with beer. If the ship sinks, they're worse than useless. But since you've decided they'll never be needed, you get more beer for your cruise.

Yes. I mean, assert spew should probably be maximally informative, which means it's probably going to vomit out a big stack trace. So for heavily used CLIs (especially if the users are other people), it can be nice to handle the bulk o

Well, even vegetable oil is hydrophobic, so "something" needn't be too horrible. (Oil would obviously wipe off too easily.) Apparently soybean wax works well: https://pmc.ncbi.nlm.nih.gov/articles/PMC7435

By adding energy (and momentum)? That seems unlikely to work. I guess you could try to shoot at things headed towards you over the horizon, to slow things down? I was assuming it was to vaporize things to make the re-condensed remnants smal

What's the difference and advantage, other than less typing, of this over: match *Arc::new("hello").as_ref() { "hi" => {} "hello" => {} _ => {} (Sorry, Rust newbie here

That's an... uncharitable interpretation of the phrase "semi-colon language". The comment made sense to me: it's not at all about semicolons, but the semicolon isn't a bad marker to distinguish between language fami

No, I'm not agreeing with you . You're agreeing with me . Wait a minute... :-) Sorry, somehow I managed to quote the portion of your message that I was agreeing with. You just said it more concisely than I could. The aspect

Yeah, I changed my SSH port for the same reason. I don't feel any more secure as a result, but now I can just watch the raw logs to see the incoming probes. They trickle in slowly, rather than being a constant flood, so I can watch the

I'm a relative beginner at Rust, but this matches my experience fairly well. Especially the part about the brittleness, where adding just one little thing can require propagating changes throughout a project. It might be adding lifetim

Sounds familiar. I'm a relative beginner at Rust, but I've started feeling like I get the hang of the borrow checker rules and can get something close to right on my first writing. Finally. Ok, maybe 2nd or 3rd, but definitely bef

Which is why a good reversible debugger is so powerful. (I use rr-project.org and Pernosco but I imagine undo.io is similar.) Don't worry about stopping at the right point. Go back to the critical points over and over again, and go bac

Oops, sorry, I think I mangled my conclusion a bit. I'm not against standardizing tests. If it doesn't get in the way of other attributes, standardization is very valuable. It's just that those results aren't enough by t

Yeah, that's fair, and I'm guessing your decision made a lot of sense in that context. Though in an interview situation, it's reasonable to not point out that you shouldn't ever do the thing that you're being asked

When I was hiring, resume quality was often a negative signal. I could sometimes tell when someone used a resume preparation service. They were good at what they did, the resumes really were much better, and the candidates correspondingly w

Ugh, I got that question in an interview. Only they wanted me to write up a basic arbitrary precision math library, in C, on paper. (I may have chosen to do it on paper.) It was harder than I expected. I didn't do that well and didn&#x

Agreed. I can't claim to be always be good at it, but this is what I strive for as well. I like talking to a candidate about something they are experienced or even expert at, and asking questions until I find the boundary of their abil
