jank is C++
If you've wondered how much a solo dev can build for seamless C++ interop on a quarter, you're about to find out. In April, jank was unable to reach into C++ at all. Toward the end of this post, I'll show some real world examples of what works today. Before that, though, I want to say thank you for the sponsorship this quarter, not only by all of my individual Github sponsors, but also by Clojuris
Today, we are excited to announce the launch of .NET 10, the most productive, modern, secure, intelligent, and performant release of .NET yet. It’s the result of another year of effort from thousands of developers around the world. This release includes thousands of performance, security, and functional improvements across the entire .NET stack-from languages and developer tools to workloads-enabl
CVE-2024-4367 - Arbitrary JavaScript execution in PDF.js — Codean Labs
This post details CVE-2024-4367, a vulnerability in PDF.js found by Codean Labs. PDF.js is a JavaScript-based PDF viewer maintained by Mozilla. This bug allows an attacker to execute arbitrary JavaScript code as soon as a malicious PDF file is opened. This affects all Firefox users (<126) because PDF.js is used by Firefox to show PDF files, but also seriously impacts many web- and Electron-based a
缶つぶし機とソフトウェア移行技術 - Refactoring to Rust の読書感想文 - じゃあ、おうちで学べる
はじめに ——あるいは、「知っている」と「理解している」の間 Rustのことは、知っていた。学習もしていた。実務でも使っていた。 でも、それは知っているつもりだった。 知ってるつもり 無知の科学 (ハヤカワ文庫NF) 作者:スティーブン スローマン,フィリップ ファーンバック早川書房Amazon 日々Rustで開発し、BoxとRcとArcを使い分け、tokio::spawnでタスクを生成し、?演算子を当たり前のように書いている。FFI？PyO3使えばいいでしょ。WebAssembly？wasm-bindgenがあるじゃない。技術的には、確かに「使える」レベルにはあった。 でも、心のどこかで感じていた違和感があった。 オートバイのエンジンを分解できる人と、エンジンが動く原理を理解している人は違う。コードが動くことと、なぜそう書くべきかを理解することも違う。私は前者だった。メカニックではあった
Hypershell: A Type-Level DSL for Shell-Scripting in Rust | Context-Generic Programming
Discuss on Reddit, Lobsters, and Hacker News. Summary I am thrilled to introduce Hypershell, a modular, type-level domain-specific language (DSL) for writing shell-script-like programs in Rust. Hypershell is powered by context-generic programming (CGP), which makes it possible for users to extend or modify both the language syntax and semantics.

Text2Landscape: Visualize a Text in Multiple Spaces with R — Force-directed networks, Biofabric, Word Embeddings, Principal Component Analysis and Self-Organizing Maps
First Visualizations: Frequencies Let us first visualize word frequencies. We can get these frequencies with the quanteda package, which implies transforming the column of lemmas (text.lemmas$lemma) into a quanteda tokens object, then to a document-feature matrix. Doing so, we only retain significant parts of phrases (nous, proper nouns, verbs and adjectives). This only partially spares us the tas
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,

I'll talk about the positives, but also discuss the things that we found challenging or suboptimal in our experience. Last year, my team at Shopify implemented YJIT, a new Just-In-Time (JIT) compiler for CRuby, which was recently upstreamed as part

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
Introduction to Go 1.20 The latest Go release, version 1.20, arrives six months after Go 1.19. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language Go 1.20 includes four changes to the language. Go
My thoughts on writing a Minecraft server from scratch (in Bash) For the past year or so, I've been thinking about writing a Minecraft server in Bash as a thought excercise. I once tried that before with the Classic protocol (the one from 2009), but I quickly realized there wasn't really a way to properly parse binary data in bash. Take the following code sample: function a() { read -n 2 uwu echo

TLDR The relational model is great: A shared universal data model allows cooperation between programs written in many different languages, running on different machines and with different lifespans. Normalization allows updating data without worrying about forgetting to update derived data. Physical data independence allows changing data-structures and query plans without having to change all of y
TikTok has a reputation for its aggressive data collection. In fact, an article published on 22 December 2022 uncovered how ByteDance spied on multiple Forbes journalists using TikTok. While some of the data they collect may seem benign, it can be used to build a detailed profile of each user. Information such as user location, device type, and various hardware metrics are combined to create a uni
If you are a Rubyist, you’ve likely been writing # frozen_string_literal: true at the top of most of your Ruby source code files, or at the very least, that you’ve seen it in some other projects. Based on informal discussions at conferences and online, it seems that what this magic comment really is about is not always well understood, so I figured it would be worth talking about why it’s there, w

We are proud to release DuckDB 1.3.0. This release of DuckDB is named “Ossivalis” after Bucephala Ossivalis, an ancestor of the Goldeneye duck that lived mil
slices package function signatures The slices.Clone function is pretty simple: it makes a copy of a slice of any type. func Clone[S ~[]E, E any](s S) S { return append(s[:0:0], s...) } This works because appending to a slice with zero capacity will allocate a new backing array. The function body winds up being shorter than the function signature, which is in part because the body is short, but als
When Your Hash Becomes a String: Hunting Ruby's Million-to-One Memory Bug

jq で IP アドレスを sort_by しようと思ったがうまくいかなかったので大人しく sort -V を使った | DevelopersIO
コンバンハ、千葉（幸）です。 AWS サービスの IP レンジの確認にip-ranges.jsonを jq でフィルタリングすることがしばしばあります。 そのまま実行すると IP プレフィックスは整列されていない状態で出力されるため、ソートしたいと考えました。 jq の機能に sort が含まれているため、そちらでなんとかできないかと思い試してみました。 まとめ jq の sort_byを使用すると文字列としてソートされるため期待した並びにならない jq でソートするのは諦めてパイプしてsortを使用しよう sortを使用する場合は-Vオプションを使用しよう （追記）jq だけでも split() や map() を使用すれば実現できる……! ip-ranges.json に jq を使用する AWS サービスが使用する IP アドレス範囲は、ip-ranges.jsonとして公開されてい
