使用 gofn 和 pipe 助力 Golang 函數式編程
今天要介紹的是兩個在函數式編程裏面很有用的 package，通過使用 gofn[1] 和 pipe[2] 庫讓 Go 的函數式編程更強大。Go 的函數式編程由於本質上，Go 並不像 Haskell 或 Erlang 那樣是純函數式語言，但這並不意味着我們不能應用函數式編程的概念來編寫簡潔、可讀和高效的代碼。這正是 gofn 和 pipe 發揮作用的地方。gofn 和 pipegofn：一個在 Go ⌘ Read more

灯塔之下，科学璀璨

1、 为什么要做《某科学的超级实验室》

《某科学的超级实验室》是一个“探室”主题的系列纪录片，其实在灯塔计划之前，我就已经尝试做过两期内容，

在我看来，这个项目想要展现两个方面，一个是科学家的精神面貌，另一个是我国的大科学装置。为什么要做这个主题呢？因为我们自己作为一个科研人员，对于科研人员是一种什么样的状态，什么样的表现，有着比较深入的理解。但是感觉大众对于科学家这个群体还是比较陌生的，而且会受影视作品的影响，对科学家有一些刻板印象。我希望想通过一些视频去把它展现给大众，让大家真正的去了解科学家到底是什么样子的，科研工作到底是什么样子的。

↳ In-reply-to » @bender I don't mind the character limit. If I hit it and I still have more to say, it's a good reminder that I should probably write a note instead. I like to POSSE anything that might have value outside of the current conversation.

@mckinley@twtxt.net, in your blog, I think a “line-heigh” of 1.5 (if I remember correctly you are setting it on the “body” on CSS) will make it more legible.
