I think the web is culturally incapable of standardizing GUI elements. The nature of web development is to rebuild from scratch. Standard buttons and menus look so vanilla, let's instead style a div with an onClick handler, let's

PR author here, these are two great questions. The Joel blog post which you referenced is excellent, and is a major influence on my thinking. Joel identifies "from scratch" rewrites as a major mistake. Don't throw away code!

DLL Hell comes when you have multiple versions of dynamically linked libraries from third parties. In practice, Swift's dynamic linking exists to support Apple's own first-party libraries which are shipped with the system, so ther

Apple uses dynamic linking to enable its OSes to evolve. Apple's libraries talk to daemons using IPC protocols such as XPC or MIG; if those libraries were statically linked, the daemons would have to support old protocols forever. And

Very interesting, TIL, thank you.

Fascinating. What mutex allows being released from another thread? I believe you they exist, I have just never heard of such a thing.

I overall like this article and share your admiration for semaphores; however this part ain't so: > there’s not much theoretical benefit to such a binary semaphore over a mutex – in fact, they’re interchangeable Not interchangeable!

Great tip, I wasn't aware of that crate!

I agree that e.g. locating .mo files is out of scope for a stdlib, but runtime format strings seems like something the stdlib could do. Because it does not, std::fmt is borderline useless for software which wants to support multiple languag

That's a depressing answer, that nobody bothers. gettext seems pretty difficult to use in Rust - there's no obvious way to apply a runtime format string "My name is {1}". https://blog.hackeriet.no/rust-an

How do Rust projects localize their format strings?

This is such a cool feature on Macs. My iPhone receives the OTP via text message, it gets forwarded to Messages on my Mac, and then desktop Safari offers to enter the code. It all takes less than a second. Do other platforms have this? Hone

This is a major sticking point for us. Many of our repos are 3rd party, made available to us under different licenses. Some require individuals to be licensed, and so we use ACLs for both read and write access. Some of our source is export-

How do monorepos work with something like gitlab or github, which expect a CI file in the repo root? My workplace has dozens of repos, and they all have separate CI needs and test suites. Trying to shoehorn them all into a single set of CI

This is a valid observation. Most NaN-tagging schemes only perform arithmetic once the values are determined to not be NaN, and so avoid any penalty. In this scheme always perform arithmetic on NaNs, so if the uarch imposes a penalty it wil

With the caveat that syntax is the ultimate bikeshed topic, one (IMO) syntactic wart is the special pattern syntax: 1. "Operators" have different meanings. `1 | 2` and `1..=2` mean something different in patterns than in expressio

Curious why the author chose not to discuss macros? You encounter them immediately with a Hello World.

Good article. The simple way to think about this is that overflow occurs when the sign of the addends agree, and the sum has the opposite sign. The bit tricks then write themselves.

Google contains multitudes. Android, Chrome, and ChromeOS are examples of large Google projects that do not use Perforce and are routinely built locally.

I frequently implemented this from the other side at Apple. You'd be shocked at how much software enables features based on a `==` OS version check. When the OS bumps its version, the software regresses to some earlier behavior. Lying

JITs do indeed modify already-compiled code. For example, JavaScriptCore has a notion of a "patchable jump." These are jump instructions intended to be modified later. They may initially point to slow paths, and are later patched

Probably. I would like to see how it's done, build.rs does seem like the most sensible place. Debugging build.rs is painful.

Part of the answer is that C++ wants to interrogate your system or build root to understand its capabilities. "Call this function if available" or "Access this variable if it exists" are more common in C++ projects, comp

Branches add control flow which can inhibit other optimizations, such as vectorization. Compare the codegen of these two functions to double the first 64 elements in a u8 slice: https://rust.godbolt.org/z/hccWGv889 The

The article does not say what a MicroVM is. From what I can gather, it's using KVM to virtualize specifically a Linux kernel. In this way, Firecracker is somewhat intermediate between Docker (which shares the host kernel) and Vagrant (

dead_code is required because Rust compiles each integration test as a separate crate. This causes spurious warnings to be emitted if you want to share code between tests. See https://github.com/rust-lang/rust/issu
