Bulk remove iTerm2 color schemes.
View gist:11312110
# There was a day where I have too many color schemes in iTerm2 and I want to remove them all.
# iTerm2 doesn't have "bulk remove" and it was literally painful to delete them one-by-one.
# iTerm2 save it's preference in ~/Library/Preferences/com.googlecode.iterm2.plist in a binary format
# What you need to do is basically copy that somewhere, convert to xml and remove color schemes in the xml files.
$ cd /tmp/
$ cp ~/Library/Preferences/com.googlecode.iterm2.plist .
$ plutil -convert xml1 com.googlecode.iterm2.plist
$ vi com.googlecode.iterm2.plist

Instructions on how to get a Plover keymap working with NKRO on ErgoDox keyboard.
View plover-nkro-on-ergodox.md

[Plover][] is an awesome open source stenography program, but to run the software [you need an NKRO keyboard][nkro]. The [ErgoDox keyboard][ergodox] can be made to run in NKRO mode by following these steps.

Install dependencies

These instructions are based on this document, which assumes you're using Windows. I'm using a mac, and I had to download and install the [CrossPack for AVR Development][crosspack] before the build process worked.

Download the source

The NKRO firmware and Plover keymap can be found in the simon_layout branch of @shayneholmes fork of tmk_keyboard. Get the source:
