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

Async Rust Is A Bad Language
But to get at whatever the hell I mean by that, we need to talk about why async Rust exists in the first place. Let’s talk about: Modern Concurrency: They’re Green, They’re Mean, & They Ate My Machine Suppose we want our code to go fast. We have two big problems to solve: We want to use the whole computer. Code runs on CPUs, and in 2023, even my phone has eight of the damn things. If I want to use
When a rewrite isn’t: rebuilding Slack on the desktop - Slack Engineering
A new version of Slack is rolling out for our desktop customers, built from the ground up to be faster, more efficient, and easier to work on. Conventional wisdom holds that you should never rewrite your code from scratch, and that’s good advice. Time spent rewriting something that already works is time that won’t be spent making our customers working lives simpler, more pleasant, and more product
Today we’re excited to announce the release of TypeScript 4.5! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript by adding statically checked types. When you use static types, you can run the TypeScript compiler to check for bugs like typos and mismatches in the shapes of your data, and get handy suggestions. These types don’t change your program, and you can re
copilot-explorer
Copilot Internals | thakkarparth007.github.io Github Copilot has been incredibly useful to me. It can often magically read my mind and make useful suggestions. The thing that surprised me the most was its ability to correctly “guess” functions/variables from surrounding code – including from other files. This can only happen, if the copilot extension sends valuable information from surrounding cod
Why SQLite Uses Bytecode
1. Introduction Every SQL database engine works in roughly the same way: It first translates the input SQL text into a "prepared statement". Then it "executes" the prepared statement to generate a result. A prepared statement is an object that represents the steps needed to accomplish the input SQL. Or, to think of it in another way, the prepared statement is the SQL statement translated into a fo

The Development of the C Language* Dennis M. Ritchie Bell Labs/Lucent Technologies Murray Hill, NJ 07974 USA dmr@bell-labs.com ABSTRACT The C programming language was devised in the early 1970s as a system implementation language for the nascent Unix operating system. Derived from the typeless language BCPL, it evolved a type structure; created on a tiny machine as a tool to improve a meager progr

LISP in Two Days with Rust 10 Jul 2019 As a sidetrack from the development of my programming language I’ve spent some time developing a LISP. The plan is to use the language as a testing ground for experimentation with transforming an AST in Rust. The syntax of LISP is simple and was developed to be easy to parse. I figured it would make a good starting point for an experimental compiler. The lang

The Writable Files API: Simplifying local file access | Web | Google Developers
What is the File System Access API? The File System Access API (formerly known as Native File System API and prior to that it was called Writeable Files API) enables developers to build powerful web apps that interact with files on the user's local device, such as IDEs, photo and video editors, text editors, and more. After a user grants a web app access, this API allows them to read or save chang
Flutter Project Structure: Feature-first or Layer-first?
When building large Flutter apps, one of the first things we should decide is how to structure our project. This ensures that the entire team can follow a clear convention and add features in a consistent manner. So in this article we'll explore two common approaches for structuring our project: feature-first and layer-first. We'll learn about their tradeoffs and identify common pitfalls when tryi
