Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what th
Masato Hagiwara Open in Recto Pad Google Colab Github Recto Pad TL;DR Recto is a 2D programming language that uses nested rectangles as its core syntax, encoding structure and recursion directly in space instead of a linear stream of text. Recto explores new ways to write, parse, and reason about code—and even natural language—spatially. Introduction Open in Recto Pad Virtually all the languages w

Building the fastest Lua interpreter.. automatically!
This is Part 1 of a series of posts. Part 2 is available here: Building a baseline JIT for Lua automatically It is well-known that writing a good VM for a dynamic language is never an easy job. High-performance interpreters, such as the JavaScript interpreter in Safari, or the Lua interpreter in LuaJIT, are often hand-coded in assembly. If you want a JIT compiler for better performance, well, you’
I want to write a post about Pitchfork, explaining where it comes from, why it is like it is, and how I see its future. But before I can get to that, I think I need to share my mental model on a few things, in this case, Ruby’s GVL. For quite a long time, it has been said that Rails applications are mostly IO-bound, hence Ruby’s GVL isn’t that big of a deal and that has influenced the design of so
Update 1.75.1: The update addresses these issues. Downloads: Windows: x64 Arm64 | Mac: Universal Intel silicon | Linux: deb rpm tarball Arm snap Welcome to the January 2023 release of Visual Studio Code. There are many updates in this version that we hope you'll like, some of the key highlights include: Profiles - Create and share profiles to configure extensions, settings, shortcuts, and more. VS
An interesting twist in my recent usage of SQLite was the fact that I noticed my research scripts and the database intertwine more. SQLite is unique in that it really lives in-process, unlike standalone database servers. There is a feature to that which does not get used very frequently, but can be indispensable in some situations. By the way, the talk about the system that made me me to explore S
Following up from the last post, there is a lot more we need to cover. This was intended to be the post where we talk exclusively about benchmarks and numbers. But, I have unfortunately been perfectly taunted and status-locked, like a monster whose “aggro” was pulled by a tank. The reason, of course, is due to a few folks taking issue with my outright dismissal of the C and C++ APIs (and not showi
This post is based on my RustNationUK ‘24 talk with the same title. The talk video is on youtube, the slides are served from here. Also, here’s the lyrics of the song I introduced the talk with (sung to the tune of Bob Dylan’s “The times, they are a-changin’”): Come gather Rustaceans wherever you roam and admit that our numbers have steadily grown. The community’s awesomeness ain’t set in stone, s

Contracts提案（P2900R14）がC++26に向けて採択され、C++26では契約プログラミング機能を言語サポートの下で実践できるようになります。この記事は、その契約プログラミング機能の一部として導入されている違反ハンドラというものについてのお話です。 契約プログラミング機能における違反ハンドラの概要 ユーザー定義違反ハンドラ std::contracts::contract_violation より一般的な利用 外部ツールの共通コールバック機構として 実行時エラーハンドリングのコールバック機能として（P3290R2） プロファイル機能の実行時検査におけるコールバックとして（P3081R0） 未定義動作の実行時ハンドリング機能として（P3100R0, P3229R1, P3205R0） 参考文献 契約プログラミング機能における違反ハンドラの概要 C++26の契約プログラミング機能は
"Get or create" is a very common operation for syncing data in the database, but implementing it correctly may be trickier than you may expect. If you ever had to implement it in a real system with real-life load, you may have overlooked potential race conditions, concurrency issues and even bloat! In this article I explore ways to "get ot create" in PostgresSQL. Illustration by Abstrakt Design Ta

Versus explicit state machines Versus conventional threads The subjective view: why do I like them so much? “Teach the student when the student is ready” They s
My birthday just passed, and to relax I wrote a parser combinator library. Over the last few years, I have worked quite a bit with Ningning Xie and Jeremy Yallop on parser combinators, which has led to a family of parser combinators which have optimal linear-time performance in theory, and which are many times faster than lex+yacc in practice. But these use advanced multistage programming techniqu
