A Lean Syntax Primer — overreacted
This is my opinionated syntax primer for the Lean programming language. It is far from complete and may contain inaccuracies (I’m still learning Lean myself) but this is how I wish I was introduced to it, and what I wish was clarified. #Why Lean? This post assumes you’re already eager to learn a bit of Lean. For motivation, I humbly submit to you two takes: one from me and one from its creator. #D
Multi-target projects | Gleam programming language
Gleam is a type safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam v0.34.0 has been published. Let's take a look at what's new! Multi-target projects Gleam can compile to one of two targets: Erlang or JavaScript. Some packages may only support one of the two targets, possibly because they make use of Erlang features that are not available in JavaScript,

Algebraic Effects for the Rest of Us — overreacted
Algebraic Effects for the Rest of UsJuly 21, 2019 Have you heard about algebraic effects? My first attempts to figure out what they are or why I should care about them were unsuccessful. I found a few pdfs but they only confused me more. (There’s something about academic pdfs that makes me sleepy.) But my colleague Sebastian kept referring to them as a mental model for some things we do inside of

Parallel vs concurrent in Node.js
In a heated debate over technicalities on the internet, you may have heard the argument "Yeah, that may be concurrent but not parallel computing." You're wondering what do they mean anyway? What's the difference? Most importantly, should I care? As it turns out, Node.js can be categorized into one of these. On the general level, though, as long as you keep in mind that the CPU is pretty much alway
GitHub - vanilla-manifesto/vanilla-di-manifesto: We love DI, but we don't use any DI libraries. Why?
Vanilla DI is one of the implementation approaches for Dependency Injection. And also, Vanilla DI is an approach for design. This approach has the following pros: Pros Extremely simple Extremely easy to use Dependency-free Good debuggability Good readability for beginners Good portability for most languages Good way to layered architecture But it is not a silver bullet, so this approach has the fo

JavaScript fatigue fatigue
Enough with the fatigue – tips against feeling overwhelmed: Don’t try to know everything – it’s impossible in modern web development. Given that there is always more to know, it doesn’t matter that much what you learn (unless you have a specific need). Go for depth in areas you love. Go for breadth and on-demand learning in areas you are merely interested in or think you should know more about. Wa
JavaScriptでパーサコンビネータのコンセプトを理解する(「正規表現だけに頼ってはいけない」の続き) - id:anatooのブログ
前回の記事の続き。前回は、正規表現が使えない時はパーサコンビネータを使ってみると良いということを書いた。 パーサコンビネータのためのライブラリは、以下のように各言語ごとにいくつかある。 JavaScript - Parsimmon Ruby - rparsec treetop Python - parsy PHP - PHPPEG 各言語でいくつかあるのだが、正規表現と違ってパーサコンビネータには統一的な書き方があるわけではないし、ライブラリによって使い方も様々である。なので、今まで正規表現だけ使ってきた開発者がちょっと使ってみようと思っても、使い方がよくわからずに面食らってしまうことがある。 パーサコンビネータはテキストをパースするための非常に強力な仕組みだが、その背後にある考え方を理解しなければこれらのパーサコンビネータのライブラリを使う際の障害になるだろう。逆に言うと、それさえ理解で
