Auto WiFi detection or wifi hostpot creation during boot for RPI

Note: These are rough notes and there may be some variance as versions of raspbian get updated but should be pretty reliable as a guide.

This gist provides some instructions and config in order to have your Raspberry PI automatically connect to a roamed network, however if it fails to discover an available network it will set itself up as a wireless access point for you to connect to.

Issue

My display stopped working, showed weird patterns and shut off at random. My graphics basically looked like striped christmas wrapping. I got a 15" MacBook Pro Late 2011 model.

Solution

Some googling for the issue on my iPad showed that baking my logic board, as weird as it sounds, might actually be the solution. Since it was a dead logic board in my eyes, I was willing to give it a try. Correctly put, this process should reflow some of the solder on the logic board and connect it properly.

And later I found out these video issues are a thing, thus Apple offering a repair for these models. If you happen to have this video problems: You might want to turn it in at your local Apple repair store.

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.
