FILE SPACING:

 # double space a file
 sed G

 # double space a file which already has blank lines in it. Output file
 # should contain no more than one blank line between lines of text.
 sed '/^$/d;G'

# vim style tmux config

# use C-a, since it's on the home row and easier to hit than C-b
set-option -g prefix C-a

set -g base-index 1

# Easy config reload
bind-key R source-file ~/.tmux.conf \; display-message "tmux.conf reloaded."

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

• Separate big codebases into multiple repositories.

Smart Caps Lock: Remap to Control AND Escape (Linux, Mac, Windows)

把 Caps Lock 變成智慧的 Control 以及 Escape ：

• 單獨輕按一下就是 Escape 。
• 若按下時同時按著其他鍵，就會是 Control 。

這應該是 Vim 和 Emacs 的最佳解了！(Emacs? Bash 的快捷鍵就是 Emacs 系列的)

• Send Escape if you tap Caps Lock alone.

Jenkins in Docker (docker-in-docker)

Testing Jenkins flows on your local machine, or running Jenkins in production in a docker container can be a little tricky with a docker-in-docker scenario. You could install Jenkins to avoid any docker-in-docker issues, but then you have Jenkins on your machine, and the local environment is likely going to be a fairly different from the actual production build servers, which can lead to annoying and time-consuming issues to debug.

Build environment differences are precisely why there is a strong argument to be made to run build processes strictly in docker containers. If we follow the philosophy that every build step or action should run in a docker container, even the Jenkins server itself, then we get massive benefits from things like, total control over the build environment, easily modify the build environment without the possibility of adversely effecting other jobs, explicit and strongly controlled tool versions,

Understanding Nix Inputs

Every Nix derivation produces a Nix store output that has 3 things:

• Executables
• Libraries
• Data

Executables are always exported using the PATH environment variable. This is pretty much automatic.
