Making X11 apps work inside docker

TL;DR

xhost +local:docker
docker run -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix ...

Details

Every now and then I want to run X apps inside docker, and then I always hit some issues.

FP 在應用程式的高峰可能在 2013~2014 左右，那時 John Carmack port Wolf3D 到 Haskell 上，還提到：

I haven't done any functional programming since I started crunching at Oculus, but I consider the time I spent on it extremely worthwhile.

也說過：

I feel a touch of impostor syndrome when I get invited to speak at functional programming conferences.

同年 (2014) audreyt 在 FLOLAC'14 給了演講《函數程式設計的商業應用》。

In JavaScript, objects can be used to serve various purposes.

To maximise our usage of the type system, we should assign different types to our objects depending
on the desired purpose.

In this blog post I will clarify two common purposes for objects known as records and dictionaries
(aka maps), and how they can both be used with regards to the type system.
