How We Made Bracket Pair Colorization 10,000x Faster In Visual Studio Code
Version 1.93 is now available! Read about the new features and fixes from August. Bracket pair colorization 10,000x faster September 29, 2021 by Henning Dieterichs, @hediet_dev When dealing with deeply nested brackets in Visual Studio Code, it can be hard to figure out which brackets match and which do not. To make this easier, in 2016, a user named CoenraadS developed the awesome Bracket Pair Col
Today we’re excited to announce the release of TypeScript 5.0! This release brings many new features, while aiming to make TypeScript smaller, simpler, and faster. We’ve implemented the new decorators standard, added functionality to better support ESM projects in Node and bundlers, provided new ways for library authors to control generic inference, expanded our JSDoc functionality, simplified con
I often feel like javascript code in general runs much slower than it could, simply because it’s not optimized properly. Here is a summary of common optimization techniques I’ve found useful. Note that the tradeoff for performance is often readability, so the question of when to go for performance versus readability is a question left to the reader. I’ll also note that talking about optimization n
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill.

A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
Learn how to bring multithreaded applications written in other languages to WebAssembly. WebAssembly threads support is one of the most important performance additions to WebAssembly. It allows you to either run parts of your code in parallel on separate cores, or the same code over independent parts of the input data, scaling it to as many cores as the user has and significantly reducing the over

With pen and paper, anyone can write a journal entry, draw a diagram, perform a calculation, or sketch a cartoon. Digital tablets like the iPad or reMarkable can adapt pen and paper into the world of digital media. In doing so, they trade away some of paper’s advantages like cheapness and tangibility. In exchange, we get new computational powers like nondestructive editing and ease of transmission

Show navigation Writing a high-performance JavaScript engine takes more than just having a highly optimising compiler like TurboFan. Particularly for short-lived sessions, like loading websites or command line tools, there’s a lot of work that happens before the optimising compiler even has a chance to start optimising, let alone having time to generate the optimised code. This is the reason why,

I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now.

The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,
Today we’re excited to announce the release of TypeScript 5.6! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by adding syntax for types. Types describe the shapes we expect of our variables, parameters, and functions, and the TypeScript type-checker can help catch issues like typos, missing properties, and bad function calls before we even run our code.

Toggle dark mode What follows is a brain dump of everything I know about compiling Rust to WebAssembly. Enjoy. Some time ago, I wrote a blog post on how to compile C to WebAssembly without Emscripten, i.e. without the default tool that makes that process easy. In Rust, the tool that makes WebAssembly easy is called wasm-bindgen, and we are going to ditch it! At the same time, Rust is a bit differe

WebGPU is an upcoming Web API that gives you low-level, general-purpose access GPUs. I am not very experienced with graphics.

14 Linting Rules To Help You Write Asynchronous Code in JavaScript
Debugging asynchronous code in JavaScript can feel like navigating a minefield at times. You don't know when and where the console.logs will print out, and you have no idea how your code is executed. It's hard to correctly structure async code so it executes in the right order as you intend it to. Wouldn't it be nice if you had some guidance while writing asynchronous code, and to get a helpful me
What's the difference between JavaScript engines and JavaScript runtimes? - Human Who Codes
You have probably heard the terms “JavaScript engine” and “JavaScript runtime” used interchangeably to mean “a program that runs JavaScript.” These are often intermixed by referencing V8, Node.js, or some other combination of related programs. However, there is a significant difference between a JavaScript engine and a JavaScript runtime in terms of scope and functionality. Understanding this diff
Look-up-tables, more commonly referred to as LUTs, are as old as Mathematics itself. The act of precalculating things into a row or table is nothing new. But in the realm of graphics programming, this simple act unlocks some incredibly creative techniques, which both artists and programmers found when faced with tough technical hurdles. We’ll embark on a small journey, which will take us from simp
How a simple Linux kernel memory corruption bug can lead to complete system compromise
In this case, reallocating the object as one of those three types didn't seem to me like a nice way forward (although it should be possible to exploit this somehow with some effort, e.g. by using count.counter to corrupt the buf field of seq_file). Also, some systems might be using the slab_nomerge kernel command line flag, which disables this merging behavior. Another approach that I didn't look

My thoughts on writing a Minecraft server from scratch (in Bash) For the past year or so, I've been thinking about writing a Minecraft server in Bash as a thought excercise.

GitHub - endojs/Jessie: Tiny subset of JavaScript for ocap-safe universal mobile code
This document is an early draft. Comments appreciated! Thanks. Today, JavaScript is the pervasive representation for (somewhat) safe mobile code. For another representation to achieve universality quickly, it must be a subset of JavaScript, and so runs at least everywhere JavaScript runs. Whereas JSON is a simple universal representation for safe mobile data, Jessie is a simple universal represent
