> Rust couldn't solve all of these bugs, but it certainly would have drastically reduced the total amount. Well there's certainly a chronological argument that it couldn't have, but I agree with the sentiment. It saddens

I'm interested to know how the language handles memory; automatic memory reclamation without a GC and that is simpler than Rust seems like a very attractive proposition.

I admit that I'm very unexcited about non-lexical lifetimes—the cost-to-benefit ratio seems worse than the current model. The current lifetime system is simple to understand: a value is live until its owning variable goes out of scope

If you don't mind a bit of a re-education, Rust allows you to write programs that are as fast as those written in C or C++ and you'll be more confident that they don't have strange memory bugs. (Reason: the ownership model

The sad thing is that Rich Hickey had some very good videos when Clojure was a new thing back in 2008–2009. Unfortunately, I've disagreed vehemently with most of his talks since then. In this case, it's completely illogical that

(Also non-native English speaker) I feel the same way. I think that when I speak, my listener gives me cues (e.g., nodding or frowning) and I react to them: I reformulate if they seem confused or I keep going if they look satisfied. When

I find Jon enraging, especially when he whines about Emacs: a number of the things he complains about are either fixed in newer versions of Emacs (he's still on Emacs 23) or packages offer a vastly improved user experience.

Because of integer overflows and floating-point operations, the notion of equivalent mathematical expressions is tricky. fn main() { let a: i8 = 125; let b: i8 = 3; let c: i8 = (a + b) / 2; let d:

No, he had intrusive pointers; his rectangle nodes were in a couple of doubly-linked lists and an AVL tree at the same time.

The naïve Rust part is explained in a video [1] that Bryan released a couple of weeks ago; instead of using bespoke data structures for his problem, he shoved everything into HashMaps and BTreeSets and used numerical indices rather than poi

In our continuous integration system at work, I've enabled sccache with the S3 backend. This reduced the compile times from 20-25 minutes (tests and release build) to 8-9 minutes. Still longer than I like, but it's possible to e

If you have a blog, that would make for an amazing entry, going from 50% slower to 25% faster. Edit: HOLY CRAP! I have a program written in Rust, ppbert[1], and I just tried wrapping my StdoutLock object in a BufWriter, and I improved the

Language-wise, Rust is really top-notch, I find it hard to fault any design decision. There are some design choices that annoy me (e.g., two closure types can never be equal), but there is always a fact-based rationale for why things are t

I'm not sure why you would prefer to (1) create a new trait, (2) create a custom derive for that trait, (3) derive that trait for all the types you want to debug over assigning to a variable and printing. It sounds like an over-engine

Without going into specifics, can you outline the kind of illegal activities that might appear in a git commit history? I'm guessing copyright infringements mostly?

Agreed. I learned awk a bit late in my Linux journey (started using Linux in 1999, learned awk in 2016), but I can't imagine not using it daily now. Great tool to manipulate data, and it's great for when you want a Unix tool that

You have two dialects: Safe Rust and Unsafe Rust. Safe Rust is regular Rust code, the kind of code that you should write 99.9% of the time. Unsafe Rust is a superset of Safe Rust; all of the Safe Rust checks still apply. Within an unsa

The main issue with this is that AsciiDoc cannot express semantics. When writing manpages, you can specify that something is a flag or a function parameter, etc.

I mentioned a few months ago in a similar thread that I now actively try to recognize when I'm creating an incomprehensible 300-line "abstraction" in order to avoid copying four line of code.

mg also has keyboard macros, but it doesn't have UTF-8 support yet, which is the reason why I prefer to use jmacs for quick edits.
