This is why you should never use parser combinators and PEG
Let me tell you why you should (nearly) never use PEG (parsing expression grammars). Nearly everything I will say applies to parser combinators (parsec in Haskell, nom in Rust), too. So, don't use PEG. Use CFGs (context-free grammars) instead. They are more natural. I feel that CFGs more naturally represent how we think. Thus when you have some language in your head and you try to write it down as
rust is not about memory safety
01 june, 2024 most of rust discussions nowadays revolve around memory safety, and how it is safer than C / C++ / zig / go / whatever language is being trashed on twitter that day. while yes, that is true - not that the bar for most of these is particularly high - what I think is the main point of the language is always glossed over: correctness. when one tries to criticize any of the aforementione
Nushell
Pipelines to control any OSNu works on Linux, macOS, BSD, and Windows. Learn it once, then use it anywhere. Everything is dataNu pipelines use structured data so you can safely select, filter, and sort the same way every time. Stop parsing strings and start solving problems. Nu works with existing dataNu speaks JSON, YAML, SQLite, Excel, and more out of the box. It's easy to bring data into a Nu p
Rust is for the Engine, Not the Game - Barrett's Club
Last updated on June 6, 2024. Rust is for the Engine, Not the Game Macros are cool! But, if we're going to create another language anyways... LogLog Games recently posted Leaving Rust gamedev after 3 years, a must-read article for folks who're doing game development in Rust. It focuses on a small indie developer organization and their experiences with Rust development. If you haven't given it a re
Rust and dynamically-sized thin pointers
One of Rust's notable differences from C is its requirement that all values have a defined size, which enables runtime bounds-checking and advanced static analysis tooling such as MIRI. For dynamically-sized types (DSTs) this requirement is implemented using thick pointers, such that each pointer to a dynamically-sized value is an (address, size) tuple. Thick pointers are more convenient and easie
Enter paradis — A new chapter in Rust's parallelism story | Andreas Longva
Rust is a great language for data-parallel problems with relatively simple parallel access patterns. It particularly excels when the data can be split up into contiguous chunks. On the other hand, things can get messy for parallel access patterns that are non-contiguous or less structured. In this post, I will show you an uglier side of parallelism in Rust. Thankfully, it is not a fundamental flaw
How to Make a CSS Timer – Frontend Masters Boost
There are times when we can use a timer on websites. 😉 Perhaps we want to time a quiz or put pressure on a survey. Maybe we are just trying to making a dramatic countdown after a user has done something great like successfully booking a concert ticket. We could be trying to build a micro time management tool (think Pomodoro). Or it could just be an alternative to a spinner UI. When those situatio
The borrow checker within · baby steps
This blog is where I post up various half-baked ideas that I have. All PostsCategoriesGitHubTwitterRSS/Atom feeds This post lays out a 4-part roadmap for the borrow checker that I call “the borrow checker within”. These changes are meant to help Rust become a better version of itself, enabling patterns of code which feel like they fit within Rust’s spirit, but run afoul of the letter of its law. I

Improving Web Accessibility with Web Platform Tests
Last year, a colleague introduced me to the Interop Accessibility project. I immediately resonated with its charge to “improve the state of accessibility across the entire web, regardless of which platform, browser, or assistive technology.” The project’s mission was compelling but it also represented, from my perspective, a transformative example of shifting accessibility to the level of web plat
ECMAScript 2024 features: resizing and transferring ArrayBuffers
ECMAScript 2024 features: resizing and transferring ArrayBuffers In this blog post, we examine ArrayBuffer features that were introduced in ECMAScript 2024: “In-place resizable ArrayBuffers”, proposed by Shu-yu Guo “ArrayBuffer.prototype.transfer and friends” proposed by Shu-yu Guo, Jordan Harband and Yagiz Nizipli What are ArrayBuffers? # The following classes provide an API for handling binary
CSS Length Units | CSS-Tricks
Overview Many CSS properties accept numbers as values. Sometimes those are whole numbers. Sometimes they’re decimals and fractions. Other times, they’re percentages. Whatever they are, the unit that follows a number determines the number’s computed length. And by “length” we mean any sort of distance that can be described as a number, such as the physical dimensions of an element, a measure of tim
