To chime in with my personal experience, I did actually lose almost two days on hunting down an unintended copy constructor call. The method expected a "const B&" but was called with a "const A&". It also happene

That's a great point! If you can guarantee that the threads don't outlive the Mutex an Arc is not even necessary.

It's very cool that mutexes on Linux don't require an allocation anymore! A very common pattern is to use an Arc<Mutex<T>> for sharing ownership across threads and as far as I can tell this will now only require one al

Thanks for the explanation, I will definitely check out the docs on algebraic effects!

Looks very cool! Can somebody enlighten me what's happening in the Algebraic Effects example? Specifically this part: handle f () | flip () -> (resume true + resume false) / 2.0 Does `handle f ()` call `calculation

OT: sqlx tip: you can compile without a DB connection by either using the non-macro version of the queries (at the cost of losing compile time query checking) or you "bake" the query checks using sqlx-cli which produces files that

So what it boils down to: The old (1st generation) vaccine is still being held in storage but currently not available to the general public (says https://www.bag.admin.ch/bag/de/home/krankheiten/krankheit

Yes, I think it boils down to whether creating a derived pointer from a restrict pointer and then using both is allowed. I just had a look at the C standard and I think it is allowed if the derived pointer is (what the standard calls) &quot

by dthul 4y ago
Indeed I don't think C cares about how the pointers you mark as "restrict" were constructed, it just cares about how you actually use the pointers and in the example code they are never used in an "overlapping" way.

Such non-constructive comments are not appreciated here.

This document describes the smart contract for an NFT: https://eips.ethereum.org/EIPS/eip-721 The base contract does not contain any info about the asset the NFT applies to and the metadata extension only allows you to

Just want to mention that Cargo (don't know about others like NPM) handles it a bit differently. You are quite flexible in specifying the versions of your direct dependencies and you can fix major, minor or patch versions or do even mo

I was wondering whether the Rust compiler could treat Result enums specially and implement them as panics under the hood. But I guess such optimizations are not really feasible because they might change behavior when unwinding through FFI f

Thanks! I didn't realize that it required curly braces and only went off of the red squiggly line my IDE put there instead of reading the helpful compiler output.

Really looking forward to const generics becoming more and more useful in the future! A current limitation I hit yesterday is that you can't use a (non-literal) expression as a const generic parameter yet. I wanted to specify 32KiB as

Does anybody know what happens when the bid is not equal to but higher than the ask? What is the price that will be used? Or will this not lead to a transaction at all?

I went with a hybrid approach in university: I didn't take any notes in class so I could actually focus on the lecture and actively think along. Later, in preparation for the exam, I would go through all slides again and turn them into

I wonder if this mechanism could also be used for bounds checking when accessing dynamically sized collections. That would be a boon for C/C++ as well as safe languages. But I guess it can not because while the underlying allocation ma

Did that behavior change at some point? I'm on Big Sur and clicking on an unfocused window will focus it and trigger whatever button your mouse landed on. Edit: it seems to depend on the kind of button(?)

I guess it would depend on how that NFT was marketed at the time of purchase. If a piece of digital artwork was displayed on the NFT's web page and the buyer believed that they would get ownership of that artwork in return for their mo

Good to know! I don't know much about the blockchain space and have only looked more closely at Ethereum so far.
