Version 1.108 is now available! Read about the new features and fixes from December. 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 Colorizer extension to colorize matching

Ruby is a dynamic, open-source programming language known for its simplicity and productivity. With an expressive and elegant syntax, part of the Ruby philosophy is to make developers happy. It is often used for web development with a range of different frameworks, and for scripting, allowing for fast iterations when building prototypes. This topic goes into detail about setting up and using Ruby
お久しぶりです。SRE の @babarot です。2022年4月に書いた 10X に SRE Team ができるまでとこれから 以来、3年ぶり2度目の文章です。10X に SRE チームができてから3年以上が経ち、その間の活動や成果などについて沈黙しまくっていたのですが、振り返ると実に多くのことを達成してきました。最近は会社的にも嬉しいニュースがあり、これから更にやっていくぞ 🔥というフェーズに来ております。この3年間、黙々と頑張りすぎてアウトプットがなかなかできていなかったので、このブログ記事ではこれまでの SRE の取り組みを軽く紹介しつつ、今後はそれぞれのテーマに深ぼったネタを定期的に記事にして投稿してきます！まずは第1弾として2025年時点の 10X SRE の現状報告ブログをどうぞ。 10X インフラの歴史 宣言的なインフラ管理 インフラの構成管理 (Terraform) ワ
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

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
On Sunday March 6, we migrated Stripe’s largest JavaScript codebase (powering the Stripe Dashboard) from Flow to TypeScript. In a single pull request, we converted more than 3.7 million lines of code. The next day, hundreds of engineers came in to start writing TypeScript for their projects. Seriously unreal. I remember a short time ago laughing at the idea of typescript ever landing at Stripe, an

Why LSP?
Apr 25, 2022 LSP (language server protocol) is fairly popular today. There’s a standard explanation of why that is the case. You probably have seen this picture before: I believe that this standard explanation of LSP popularity is wrong. In this post, I suggest an alternative picture. Standard Explanation The explanation goes like this: There are M editors and N languages. If you want to support a

Today we excited to announce the availability of TypeScript 5.7! If you’re not familiar with TypeScript, it’s a language that builds on JavaScript by adding syntax for type declarations and annotations. This syntax can be used by the TypeScript compiler to type-check our code, and it can also be erased to emit clean, idiomatic JavaScript code. Type-checking is helpful because it can catch bugs in
Today we are excited to announce the availability of TypeScript 4.9! If you’re not familiar with TypeScript, it’s a language that builds on JavaScript by adding types and type-checking. Types can describe things like the shapes of our objects, how functions can be called, and whether a property can be null or undefined. TypeScript can check these types to make sure we’re not making mistakes in our

Today is TypeScript’s birthday! But this birthday is a special one – 10 years ago today, on October 1st, 2012, TypeScript was unveiled publicly for the first time. The Early Days When TypeScript first debuted, there was a lot of skepticism – and understandably so. To some JavaScript users, a team trying to bring static types to JavaScript might have sounded like an evil plot or a joke. But the fea

Rust is an appealing language for building user interfaces for a variety of reasons, especially the promise of delivering both performance and safety. However, finding a good architecture is challenging. Architectures that work well in other languages generally don’t adapt well to Rust, mostly because they rely on shared mutable state and that is not idiomatic Rust, to put it mildly. It is sometim
Syntax Highlighting in Hand-Coded Websites The problem I have been trying to identify practical reasons why hand-coding websites with HTML and CSS is so hard (by hand-coding, I mean not relying on frameworks, generators or 3rd party scripts that modify the DOM). Let's say, I want to make a blog. What are the actual things that prevent me from making—and maintaining—it by hand? What would it take t

The real 0.5 was the friends we made along the way The long-awaited release of Neovim v0.5.0 finally happened on July 2, 2021. It was worth the wait: With over 4000 commits, it is so big that it broke some of the release tooling. These notes focus on the most user-visible improvements, of which the biggest are: Lua as a first-class scripting and configuration language, Language server protocol (LS
Aug 17, 2023 There are two main historical trends when choosing an implementation language for something compiler-shaped. For more language-centric tasks, like a formal specification, or a toy hobby language, OCaml makes most sense. See, for example, plzoo or WebAssembly reference interpreter. For something implementation-centric and production ready, C++ is often chosen: LLVM, clang, v8, HotSpot

Emergence of economic and social disparities through competitive gift-giving
Several tiers of social organization with varying economic and social disparities have been observed. However, a quantitative characterization of the types and the causal mechanisms for the transitions have hardly been explained. While anthropologists have emphasized that gift exchange, rather than market exchange, prevails in traditional societies and shapes social relations, few mathematical stu
