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
REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with
This post is about why we need a coroutine package for Go, and what it would look like. But first, what are coroutines? Every programmer today is familiar with function calls (subroutines): F calls G, which stops F and runs G. G does its work, potentially calling and waiting for other functions, and eventually returns. When G returns, G is gone and F continues running. In this pattern, only one fu
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
A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
We Love You, TypeScriptFor nearly five years now, Motion has operated in a large TypeScript monorepo. At its peak, it was roughly ~2.5 million lines of code after excluding comments, node_modules, etc. To manage this, we used Vercel’s rather excellent Turborepo build system. This is not a blog post hating on TypeScript — quite the opposite! Motion would likely not even have survived until today wi
鈴木たかのりです。今月のPython Monthly Topicsでは、Python 3.10から導入されたBetter error messagesについて紹介します。Better error messagesがどういったものであるかの紹介と、どのようにこのエラーメッセージが出力されているか、Python内部の処理についても触れようと思います。 Better error messagesとは Python 3.10からBetter error messagesという機能が追加されました。この機能は名前のとおり「エラーメッセージを改善」するものです。「エラーメッセージの改善」により以前よりもわかりやすいエラーメッセージが出力され、ユーザーがエラーの意味に気づきやすくなりました。 例として、以下のようなリストの閉じカッコ（]）を忘れたコードを実行し、出力されるエラーメッセージを見比べてみま
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
Introduction Data preprocessing is a necessary step in any machine learning workflow, affecting both the model’s effectiveness and the ease of maintenance. While scikit-learn is commonly used for preprocessing due to its integration with the broader Python ecosystem, DuckDB offers a practical alternative by enabling SQL-based data transformations within Python. Its declarative syntax supports modu

Logica is an open source declarative logic programming language for data manipulation. Logica extends syntax of logic programming for intuitive and efficient data manipulation. It compiles to SQL thus providing you access to the power of SQL engines with the convenience of logic programming syntax. Logica can compiles to SQL dialects of DuckDB, SQLite, Google BigQuery and Postgres. This makes it p

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However

One of the most recognizable features of a languages is its syntax. What are some of the things about syntax that matter? What questions might you ask if you were creating a syntax for your own language? Motivation A programming language gives us a way structure our thoughts.

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

Why People are Angry over Go 1.23 Iterators - gingerBill
NOTE: This is based on, but completely rewritten, from a Twitter post: https://x.com/TheGingerBill/status/1802645945642799423 TL;DR It makes Go feel too “functional” rather than being an unabashed imperative language. I recently saw a post on Twitter showing the upcoming Go iterator design for Go 1.23 (August 2024). From what I can gather, many people seem to dislike the design. I wanted to give m

The Andrej Karpathy episode.
