Published on December 14, 2020 · Updated on December 16, 2020 Bash scripts. Almost anyone needs to write one sooner or later. Almost no one says “yeah, I love writing them”. And that’s why almost everyone is putting low attention while writing them. I won’t try to make you a Bash expert (since I’m not a one either), but I will show you a minimal template that will make your scripts safer. You

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-
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

Fish 4.0: The Fish Of Theseus
About two years ago, our head maintainer @ridiculousfish opened what quickly became our most-read pull request: #9512 - Rewrite it in Rust Truth be told, we did not quite expect that to be as popular as it was. It was written as a bit of an in-joke for the fish developers first, and not really as a press release to be shared far and wide. We didn’t post it anywhere, but other people did, and we go
I use Claude Code. A lot. As a hobbyist, I run it in a VM several times a week on side projects, often with --dangerously-skip-permissions to vibe code whatever idea is on my mind. Professionally, part of my team builds the AI-IDE rules and tooling for our engineering team that consumes several billion tokens per month just for codegen. The CLI agent space is getting crowded and between Claude Cod

What used to take an entire development sprint now ships in a single afternoon. The numbers prove it: according to Stack Overflow's 2024 Developer Survey of over 65,000 developers, 76% are now using or planning to use AI coding assistants in their development process—up from 70% the previous year. The shift from "AI is a novelty" to "AI is how developers code" happened faster than anyone predicted

State of Text Rendering 2024
Preface In 2009 I wrote State of Text Rendering, as a high-level review of the Free Software text rendering stack, with a focus on shaping, and mostly in the context of the GNOME Desktop. Since then, I have spent around twelve years working on various Google products to improve fonts and text rendering: all Open Source work. When I wrote that text in 2009, my main assignment was to finish HarfBuzz
Rust Programming Language Tutorial – How to Build a To-Do List App
By Claudio Restifo Since its first open-source release in 2015, the Rust programming language has gained a lot of attention from the community. It's also been voted the most loved programming language on StackOverflow's developer survey each year since 2016. Rust was designed by Mozilla and is considered a system programming language (like C or C++). It has no garbage collector, which makes its pe
