Sure, but let's be clear: it's a tradeoff. If every program reserved as much memory at startup as needed to service 100% of its theoretically-anticipated usage, the amount of programs we could run in parallel would be drastically

To be fair, that's just an artifact Python's chosen design. A different language could make it so that acquiring the object whose context is being managed could require one to use the context manager. For example, in Python terms,

Windows is horrible, yes. But Linux definitely isn't "just as bad" as MacOS, it's already better, and it keeps getting better every year while MacOS keeps getting worse.

Using Dye as a scapegoat feels like cope. The rest of the executives were fully content with this effort, and in the end he wasn't even forced out. There's no evidence that Apple will correct its course without him.

I'll disagree here. I'd much rather have a Python-style context manager, even if it introduces a level of indentation, rather than have the sort of munged-up control flow that `defer` introduces.

It's easy to demonstrate that destructors run after evaluating `return` in Rust: struct PrintOnDrop; impl Drop for PrintOnDrop { fn drop(&mut self) { println!("dropped"); } }

It's worth emphasizing this: without the US Navy, the remaining European powers don't have the naval force to stop Russia from blockading the Baltics. And without the ability to break such a blockade, there's little hope in a

It's worse than having to parse a matching bracket, because any context where you have an item defined via nested brackets is going to be a subset of this use case. But yes, that doesn't mean you couldn't do some theoretical

Cargo is fantastic... for building Rust code. Once you start trying to also use it to build C code, you're moving outside of Cargo's wheelhouse, using features that Cargo only supports begrudgingly (like build scripts). Cargo is d

I mean, it's sort of the other way around. Cargo was built to be able to natively understand git-based dependencies, in the sense that you can bypass a crate registry and instead just point it directly at a git repo. That means that Ca

No, crates.io isn't locked to Github. crates.io uses Github as an identity provider, but there's nothing stopping them from adding more. Furthermore, they've avoided tying themselves to Github in other ways, for example, by r

I'm not sure if it even makes sense for a TOML file to be "read incrementally", because of the weird feature of TOML (inherited from INI conventions) that allow tables to be defined in a piecemeal, out-of-order fashion. Here&

Learning to read Roman numerals is secretly an exercise in mental arithmetic. You're summing numbers in your head as you go, and occasionally you'll need to keep that sum off to the side while you subtract a second number from a t

Can you be more specific? What language complexity are you referring to? Plenty of things in this post are hypothetical, not actual features being surfaced by the language.

I'm hoping that languages move away from the sigil-ified legacy of C treating pointers as special syntax and just start calling these `Ref<T>`, `PtrConst<T>`, etc.

For the purposes of the article, git isn't just being used as a database, it's being used as a protocol to replicate the database to the client to allow for offline operation and then keep those distributed copies in sync. And eve

I think there's a form of survivorship bias at work here. To use the example of Cargo, if Rust had never caught on, and thereby gotten popular enough to inflate the git-based index beyond reason, then it would never have been a problem

I'm not sure what this is arguing against here. Anyone who follows Rust knows that it's relatively modest when it comes to adding new features; most of the "features" that get added to Rust are either new stdlib APIs or
