MemoryView: Ruby 3.0 から導入される数値配列のライブラリ間共有のための仕組み - Speee DEVELOPER BLOG
Ruby コミッターの村田です。Ruby 3.0 に組み込まれる実験的な新機能を作ったので解説します。 新機能は MemoryView と名付けられました。これは C などで書かれる拡張ライブラリ向けの機能です。メモリ上の、型が均一で同一サイズの要素から構成される配列 (e.g. 行列や画像など) を、複数の拡張ライブラリ間でコピーレスで共有するために必要な仕組みを提供します。 MemoryView が導入された背景 多次元数値配列が重要な役割を持つ時代になった 深層学習やデータサイエンスの流行にあわせて、メモリ上で大きなサイズの多次元数値配列データを処理する事例が増加しています。このような数値配列データに対する処理は、複数のライブラリの機能を組み合わせて実現されます。この分野でよく使われる Python では、データ構造を numpy と pandas が提供し、機械学習アルゴリズムを

Notable changes built-in .env file support Starting from Node.js v20.6.0, Node.js supports .env files for configuring environment variables. Your configuration file should follow the INI file format, with each line containing a key-value pair for an environment variable. To initialize your Node.js application with predefined configurations, use the following CLI command: node --env-file=config.env
Tier 4 Support § Support for these targets is entirely experimental. If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available. This target may be considered deprecated by

Agenda This post aims at making you aware about the internals of the Python logging module. I often find myself struggling to use the logging module and have to refer the documentation. It's either my ignorance towards logging or probably logging isn't documented as well and crisply as it should be. So this is my take to unravel what goes on in the logging module. If you have a solid grasp of diff
Or if the package is only meant to be run on Node.js and wants to fallback to CJS on older versions that don't have require(esm): { "type": "module", "exports": { // On new version of Node.js, both require() and import get the ESM version "module-sync": "./index.js", // On older version of Node.js, where "module-sync" and require(esm) are // not supported, use the CJS version to avoid dual-package

In this write-up, I will walk you through an implementation of a string formatting library for C++ I came up with for my video game. The end result came out really compact, at only 65 lines of code—providing a skeleton that can be supplemented with additional functionality at low cost. Usage Given a format buffer… char buffer[64]; String_Buffer buf = {str, sizeof str}; …the fmt::format function pr
2024-10-16, Version 23.0.0 (Current), @RafaelGSS We’re excited to announce the release of Node.js 23! Key highlights include: Enabling require(esm) by default for Node.js applications Removing support for Windows 32-bit systems Stabilizing the node --run command Enhancements to the test runner, including glob pattern support for coverage files Node.js 23 will replace Node.js 22 as the ‘Current’ re

Rust vs C++ Formatting
In Rust, if I want to print some 32-bit unsigned value in hex, with the leading 0x, padded out with zeros, I would write that as: println!("{:#010x}", value); In C++23, if I want to do the same, that’s: std::println("{:#010x}", value); The only difference is the spelling of the name of the thing we’re calling (which is a function template in C++ and a macro in Rust) - otherwise, identical.
