関数名、メソッド名、変数名でよく使う英単語のまとめ
プログラミングをしていると関数名、メソッド名、変数名をどうするか悩みます。 ロジックより命名に時間を費やすこともざらにあります。翻訳したり、一般的な命名規則なのかいつも検索して大変です。 よく使うサイトの内容をコピってメモしておく 関数名とメソッド名の違いについて よく使う英単語のまえに、いつもごっちゃにして使っているけど、定義はこんな感じ 「関数」と「メソッド」の違い 似ているところ どちらも何か（引数）を入れると処理をして何か（戻り値）を返してくれます。 違うところ やってること自体は大差ありません。概念としては違います。 メソッドはオブジェクト指向で登場する用語で、オブジェクトの動作を定義したものです。 まずオブジェクトありきなのですね。一方の関数は、オブジェクト云々は関係ありません。 個人的な使い分け Java で登場する関数は「メソッド」です。C 言語で登場する関数は「関数」と呼

What’s in which Python
Created 17 May 2022, last updated 16 August 2025 This is a summary of what features appeared in which versions of Python. Items with a star were introduced with a __future__ import. The Python release cycle is explained in PEP 602. Each release has its own PEP with specific dates, listed here. The Python Developer’s Guide has a page summarizing the release cycles of Python versions. 3.14: expected
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

What's new in Python 3.11?Built-in TOML support, better exceptions, and typing improvements. By Tushar·InsightsPython The first beta release of Python 3.11 is out, bringing some fascinating features for us to tinker with. This is what you can expect to see in 2022's release of Python later this year. Even better error messagesPython 3.10 gave us better error messages in various regards, but Python
2024-08-06, Version 22.6.0 (Current), @RafaelGSS Experimental TypeScript support via strip types Node.js introduces the --experimental-strip-types flag for initial TypeScript support. This feature strips type annotations from .ts files, allowing them to run without transforming TypeScript-specific syntax. Current limitations include: Supports only inline type annotations, not features like enums o

The Yann LeCun et al.

AWS CloudFormation と AWS SAM を使用したサーバーレスアプリケーションの開発とデプロイ | Amazon Web Services
Amazon Web Services ブログ AWS CloudFormation と AWS SAM を使用したサーバーレスアプリケーションの開発とデプロイ お客様は、それぞれの市場で競争力を維持するために、常にイノベーションを求めています。これを達成するための1つの方法は、サービスとアプリケーションを迅速かつ効率よく構築し、それによってコストを削減しながら市場投入までの時間を短縮することです。より具体的には、アプリケーション全体をゼロから構築するよりも、サーバーレスや AI/ML などのクラウドネイティブな機能を活用して管理コストを削減したり、目的別に作られたサービスを組み合わせたり、すでに構築済みのアプリケーションを再利用したりすることが有効です。 このブログ記事では、AWS Serverless Application Model (AWS SAM) と AWS CloudFor

Faster virtual machines: Speeding up programming language execution - Mort's Ramblings
Date: 2023-01-15 Git: https://gitlab.com/mort96/blog/blob/published/content/00000-home/00015-fast-interpreters.md In this post, I hope to explore how interpreters are often implemented, what a "virtual machine" means in this context, and how to make them faster. Note: This post will contain a lot of C source code. Most of it is fairly simple C which should be easy to follow, but some familiarity w
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
For almost a complete decade—starting with discovering Haskell in about 2009 and right up until switching to a job where I used primarily Ruby and C++ in about 2019—I would have called myself first and foremost a Haskell programmer. Not necessarily a dogmatic Haskeller! I was—and still am—proudly a polyglot who bounces between languages depending on the needs of the project. However, Haskell was m
LocalStack と samlocal コマンドで SQS x Lambda 構成をローカル環境で実行する - kakakakakku blog

The Alkyne GC · mcyoung
Alkyne is a scripting language I built a couple of years ago for generating configuration blobs. Its interpreter is a naive AST walker1 that uses ARC2 for memory management, so it’s pretty slow, and I’ve been gradually writing a new evaluation engine for it. This post isn’t about Alkyne itself, that’s for another day. For now, I’d like to write down some notes for the GC I wrote3 for it, and more

Logging C Function Calls
May 19th, 2022 @ justine's web page Logging C Functions One of my favorite features of the Cosmopolitan Libc runtime is its --ftrace flag that logs C function calls. It's the simplest system for debugging programs I've ever used and it surprises me that I found no evidence of someone having invented it before. Here's one of its most important use cases. Have you ever had you debugger stupified by
redbean 2.0 release notes
redbean is a webserver in a zip executable that runs on six operating systems. The basic idea is if you want to build a web app that runs anywhere, then you download the redbean.com file, put your .html and .lua files inside it using the zip command, and then you've got a hermetic app you can deploy and share. I introduced this web server about a year ago on Hacker News, where it became the third
