TabFS
Going through the files inside a tab's folder. For example, the url.txt, text.txt, and title.txt files tell me those live properties of this tab (Read more up-to-date documentation for all of TabFS's files here.) This gives you a ton of power, because now you can apply all the existing tools on your computer that already know how to deal with files -- terminal commands, scripting languages, point-

You can check out a YouTube recording of a talk based on this blog post. I started programming in Rust several years ago, and it has gradually changed the way I design programs in other programming languages, most notably in Python. Before I started using Rust, I was usually writing Python code in a very dynamic and type-loose way, without type hints, passing and returning dictionaries everywhere,
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
REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with
I joined GitLab in October 2015, and left in December 2021 after working there for a little more than six years. While I previously wrote about leaving GitLab to work on Inko, I never discussed what it was like working for GitLab between 2015 and 2021. There are two reasons for this: I was suffering from burnout, and didn't have the energy to revisit the last six years of my life (at that time)I w

AWS Open Source Blog Sustainability with Rust Rust is a programming language implemented as a set of open source projects. It combines the performance and resource efficiency of systems programming languages like C with the memory safety of languages like Java. Rust started in 2006 as a personal project of Graydon Hoare before becoming a research project at Mozilla in 2010. Rust 1.0 launched in 20
The end of classical computer science is coming, and most of us are dinosaurs waiting for the meteor to hit. I came of age in the 1980s, programming personal computers such as the Commodore VIC-20 and Apple ][e at home. Going on to study computer science (CS) in college and ultimately getting a Ph.D. at Berkeley, the bulk of my professional training was rooted in what I will call “classical” CS: p
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
I recently realized stdout is much faster than stderr for Rust. Here are my findings after diving deep into this rabbit hole. I have been using the terminal (i.e. command-line) for most of my day-to-day things for a while now. I was always fascinated by the fact that how quick and convenient the command-line might be and that's why I'm a proponent of using CLI (command-line) or TUI (terminal user
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.

Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into C
Python is among the one of the most popular programming languages, yet it's generally not the first choice when speed is required. While it can be optimized for better performance, Python is prized for qualities other than speed, such as readability, a manageable learning curve, an expansive ecosystem, and utility in both academia and business. MIT computer scientists and their colleagues, however
This is an upcoming high performance computing book titled “Algorithms for Modern Hardware” by Sergey Slotin.

We provide some benchmarks, perspective, why we did this in the first place and what it cost us with exciting ideas from Hyrum’s Law to reinforcement learning. All changes went into open source and thus I can

written by Ruud van Asseldonk published 11 January 2023 For a data format, yaml is extremely complicated. It aims to be a human-friendly format, but in striving for that it introduces so much complexity, that I would argue it achieves the opposite result. Yaml is full of footguns and its friendliness is deceptive. In this post I want to demonstrate this through an example. This post is a rant, and

Vjeux » Birth of Prettier
React Conf is around the corner and it's been almost 10 years since Prettier was released. I figured it would be a good time to recount the journey from its early days to now. This is the story of how the "Space vs Tabs Holy War" ended, not through one side winning over the other but instead a technological invention making it the underlying source of tensions no longer being a thing. Back Story S
The JavaScript Promise Integration (JSPI) API allows WebAssembly applications that were written assuming synchronous access to external functionality to operate smoothly in an environment where the functionality is actually asynchronous. This note outlines what the core capabilities of the JSPI API are, how to access it, how to develop software for it and offers some examples to try out. What is ‘
Weird Lexical Syntax
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. Now that it's halloween, I thought I'd share some of the spookiest most surprising syntax I've seen. The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,
CUPID: for joyful coding
What started as lighthearted iconoclasm, poking at the bear of SOLID, has developed into something more concrete and tangible. If I do not think the SOLID principles are useful these days, then what would I replace them with? Can any set of principles hold for all software? What do we even mean by principles? I believe that there are properties or characteristics of software that make it a joy to
When people say “debuggers are useless and using logging and unit-tests is much better,” I suspect many of them think that debuggers can only put breakpoints on certain lines, step-step-step through the code, and check variable values. While any reasonable debugger can indeed do all of that, it’s only the tip of the iceberg. Think about it; we could already step through the code 40 years ago, sure
Debugging in CSS means figuring out what might be the problem when you have unexpected layout results. Today, Stephanie Eckles will look at a few categories bugs often fit into, see how you can evaluate the situation, and explore techniques that help prevent these bugs. We’ve all been there, at the end of completing CSS for a layout and — what’s that? Ah! An extra scrollbar! Or maybe an element is
The current state of web application development User expectations of the web are now that you have this super-smooth no-reload experience. Unfortunately, it's an expectation that is usually delivered with single-page applications (SPAs) that rely on libraries and frameworks like React and Angular, which are very specialised tools that can be complicated to work with. A new approach is to put the
