Create a safe way to shutdown a headless raspberry pi with a tiny button.

1. Make the button:

• Cut a female-female jumper cable in half.
• Strip the ends and solder each to one pin on one side of the button.
• Clip off the pins on the other side of the button.
• Plug ends into 1 ground and 1 GPIO pin on your pi. I used GPIO #12 & the ground next to it.

Does your Mac becomes slow/unresponsive (fans kicking in etc.) when you npm install a huge project with a million tiny dependencies?

Solution:

Add an empty .metadata_never_index in /node_modules beforehand & it will prevent Spotlight from indexing all that crap.

To change to default program: FN + M

Fn + <, >, ? cycles between layers 2, 3, and 4. Fn + m should get you back to the default layer. Layers 2, 3, and 4 have red, green, and blue spacebar lights that I don't think you can turn off.

Layer 3 (Green spacebar) has the left option (windows) and left command (alt) mapped to match OSX keyboard.

To change single key LED program: PN + 4
