Brave Browser unable to block certain ads due to Rust language limitations
The title of this post is currently "Brave Browser unable to block certain ads due to Rust language limitations", which is ludicrous editorialization. Rust doesn't have regex in the language. Rust doesn't even have regex in the stdlib. The most popular crate for regex is https://crates.io/crates/regex , which is an engine whose design deliberately puts a reasonable upper bound on worst-case time complexity by deliberately excluding certain features. Guess what, if you want lookaround, there are regex engines in other crates that offer that: https://crates.io/crates/fancy-regex

fd: A simple, fast and user-friendly alternative to 'find'
Yes. I'm the one who implemented the case folding the `fd` uses (via its regex engine).
See: https://github.com/rust-lang/regex/blob/master/UNICODE.md#rl...
And then Unicode itself for more discussion on the topic: https://unicode.org/reports/tr18/#Simple_Loose_Matches
TR18 used to have a Level 3[1] with the kind of locale-specific custom tailoring support found in GNU's implementation of POSIX locales, but it was so fraught that it was retracted completely some years ago.

Zed is now open source
The homepage has a benchmark that compares Zed's "insertion latency" to other editors, and this is the description:
> Open input.rs at the end of line 21 in rust-lang/regex. Type z 10 times, measure how long it takes for each z to display since hitting the z key.
Could someone clarify what that means? My interpretation of that was to go to https://github.com/rust-lang/regex/blob/master/regex-cli/arg... and start typing 'z' at the end of line 21, but that doesn't seem to make any sense. I guess that repo got refactored and those instructions are out of date?

CryptoFlow: Building a secure and scalable system with Axum and SvelteKit - Part 3
We also used the avenue to sluggify the question title. We used regex to fish out and replace all occurrences of punctuation and symbol characters with an empty string and using the itertools crate, we joined the words back together into a single string, where each word is separated by a hyphen ("-").

Command Line Rust is a great book
Command-Line Rust taught me how to use crates like clap, assert_cmd, and regex. I felt lost before because I didn't know about Rust's ecosystem--which is arguably as important as the language itself. Also, looking up and comparing libraries is a tiring task! blessed.rs is nice but Command-Line Rust really saved me from analysis paralysis.

Common Rust Lifetime Misconceptions

Iām glad it does, and wish it took an impl Into> there, for the reasons discussed in the issue, but burntsushi has a lot more experience of the practical outcomes of this. Just something more to think about.

Advent of Code 2023 is nigh
I'm not familiar with the AoC problem. You might be able to. But RegexSet doesn't give you match offsets.
You can drop down to regex-automata, which does let you do multi-regex search and it will tell you which patterns match[1]. The docs have an example of a simple lexer[2]. But... that will only give you non-overlapping matches.
You can drop down to an even lower level of abstraction and get multi-pattern overlapping matches[3], but it's awkward. The comment there explains that I had initially tried to provide a higher level API for it, but was unsure of what the semantics should be. Getting the starting position in particular is a bit of a wrinkle.
