With Examples in Haskell!

Why I rewrite all DevOps tools in Haskell, and you should too!

Let's try something more practical this time: redesigning a Category Theory library for Scala 3.

Chapter 1 - The Story

Highlights about what happened last year.

Let us Type-Driven a TodoMVC with PureScript

Coverting code from JavaScript to PureScript is very straight forward.

Cats need Caffeine!

Typeclass Choice

As what I've been discussed in 3 Layer Scala Cake ReaderT pattern is pretty much enough for most case. So, let's dive into the ReaderT universe and see how can we factor those effects out.

I've been using Free Monad in production for a while, as the projects scale and more members contribute, the boundary of different layer reveal them self more clearly.

This is purely personal overall comparation from Functional Programming point of view, which only consider composible, extensible, and joy of FP. Performance and eco system are out of the scope.

可能看标题你觉得我疯了，什么叫用 dotfiles 管理你的 dotfiles。第一个单词 dotfiles 指将 HOME 目录下的 .XXX (它们是真的字面意思dotfiles) 文件同步到 Github 上的方式。通常情况下，我们在开发过程中装的大部分工具，都会在 HOME 目录下创建一个以 . 开头的文件或目录，放置配置或者状态。因此我们希望的是用 github 版本管理这些 配置 ，而不是 状态 。

当我们都用习惯 Promise Monad 之后，我再来介绍一个跟时间相关的 Monad reactive prograaming 中的 Stream

在函数式编程中, 递归可以说是最关健甚至唯一的循环手段, Clojure的recur可以保证得到 尾递归 优化, 而相互递归则不能用recur来保证得到优化, 因此, 另一个大法出现了 – Trampoline

通过上一篇Clojure风格的JavaScript并发编程介绍了如何用JavaScript享受到Clojure在并发编程的优势. 我决定写一系列关于如何用JavaScript玩转Clojure大法的文章. 这回要用简单的JavaScript玩转另一个Clojure的全新的概念 – Transducer.

新的草案(虽然说是草案,但你可以看到 Firefox 其实已经实现大部分的feature)离我们越来越近了, 而且我们已经可以通过 babel 在项目中使用这些新的features. 是时候让我们重新认识一下 JavaScript 了. 下面列出了一部分比较让人兴奋和期待的features.
