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

One thing I particularly liked about this vehicle was the In-V
Introducing Ezno
Ezno is an experimental compiler I have been working on and off for a while. In short, it is a JavaScript compiler featuring checking, correctness and performance for building full-stack (rendering on the client and server) websites. This post is just an overview of some of the features I have been working on which I think are quite cool as well an overview on the project philosophy ;) It is still

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

Agentic GraphRAG for Commercial Contracts | Towards Data Science
In every business, legal contracts are foundational documents that define the relationships, obligations, and responsibilities between parties. Whether it’s a partnership agreement, an NDA, or a supplier contract, these documents often contain critical information that drives decision-making, risk management, and compliance. However, navigating and extracting insights from these contracts can be a

Patterns for Building LLM-based Systems & Products [ llm engineering production 🔥 ] · 66 min read Discussions on HackerNews, Twitter, and LinkedIn “There is a large class of problems that are easy to imagine and build demos for, but extremely hard to make products out of.

A Walk with LuaJIT
The following is a chronicle of implementing a general purpose zero-instrumentation BPF based profiler for LuaJIT. Some assumptions are made about what this entails and it may be helpful to read some of our other work in this area. One major change from prior efforts is that instead of working with the original Parca unwinder we are now working with the OpenTelemetry eBPF profiler. If you missed t
If you combine this with the Unicode table, you’ll see that English is encoded with 1 byte, Cyrillic, Latin European languages, Hebrew and Arabic need 2, and Chinese, Japanese, Korean, other Asian languages, and Emoji need 3 or 4. A few important points here: First, UTF-8 is byte-compatible with ASCII. The code points 0..127, the former ASCII, are encoded with one byte, and it’s the same exact byt

みんなのPython 第5版、予約受付中です。Pythonにt文字列（template strings）が追加されます。 見た目はf文字列に似ていますが、最初にtを加えたリテラルで表記します。また、f文字列はその場で評価されますが、t文字列はTemplateオブジェクトになるのが大きな違いです。遅延評価・自動エスケープ・構造化ログなどの安全な処理を一貫して適用でき、f文字列では実現できなかったような処理が可能になります。 この記事では、簡単に機能の説明をしながら、具体的な利用方法を見てゆきます。Python 3.14から追加された可能性てんこ盛りの新機能を、便利にかしこく活用する方法について解説しましょう。 t文字列ってなに？Python 3.14で導入（string.templatelibモジュールが追加）。ステアリング・カウンシルは2025年4月10日にPEP 750を承認しました。

KDL is a small, pleasing document language with xml-like semantics that looks like you're invoking a bunch of CLI commands! It's meant to be used both as a serialization format and a configuration language, much like JSON, YAML, or XML. It looks like this: package { name "my-pkg" version "1.2.3" dependencies { // Nodes can have standalone values as well as // key/value pairs. lodash "^3.2.1" optio
In my decade-plus of maintaining my dotfiles, I’ve written a lot of little shell scripts. Here’s a big list of my personal favorites.

Proto Best Practices
Clients and servers are never updated at exactly the same time - even when you try to update them at the same time. One or the other may get rolled back. Don’t assume that you can make a breaking change and it’ll be okay because the client and server are in sync. Don’t Re-use a Tag NumberNever re-use a tag number. It messes up deserialization. Even if you think no one is using the field, don’t re-

The task today is to have a text label and an input field that can change the text in the label.

Introduction: Density Is King (With a Tiny VM) I've previously come to the conclusion that there's little reason for using bytecode in the modern world, except in order to get more compact code, for which it can be very effective. So, what kind of a bytecode engine will give you more compact code? Suppose I want a bytecode interpreter for a very small programming environment, specifically to minim
