MacBookNetworkAliveOnSleep

As someone that regularly has multiple SSH/VPN sessions open, it can be a huge inconvience to lose all the connections when I lock my screen to get up to go to a meeting, lunch, etc. This is especially true for those connections that require two factor authentication. So, how can I tell my MacBook to keep those connections alive, even though my screen is locked?

Well, turns out that it is pretty simple. All that is needed is to run the following command.

cd /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources
sudo ./airport en0 prefs DisconnectOnLogout=NO

Installing i3-gaps

Dependencies

i3-gaps has some packages that are required for it to work so install these things:

sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf xutils-dev libtool automake

You also need to install libxcb-xrm-dev, but I got Unable to locate package libxcb-xrm-dev when trying to install from the apt repositories on Ubuntu 16.04. If this happens to you, just install it from source using these commands:

mkdir tmp

djvdorp

#!/bin/bash
sudo apt install -y libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf libxcb-xrm0 libxcb-xrm-dev automake

cd /tmp

# clone the repository
git clone https://www.github.com/Airblader/i3 i3-gaps
cd i3-gaps

# compile & install

#!/bin/bash

# Docker can't pass newlines to containers if there are \n in variables in
# --env-file files. This tool creates a $1.exported file with newlines that
# can be sourced before running your container and a $1.vars for you to pass
# to --env-files so docker passes those variables to the container.

# Usage:
# dockerize-env .env
# This creates: .env.vars and .env.exported

Keyboard-only Mac Cheatsheet

Hi, I'm Lorna and I don't use a mouse. I have had RSI issues since a bad workstation setup at work in 2006. I've tried a number of extra hardware modifications but what works best for me is to use the keyboard and only the keyboard, so I'm in a good position and never reaching for anything else (except my coffee cup!). I rather unwisely took a job which required me to use a mac (I've been a linux user until now and also had the ability to choose my tools carefully) so here is my cheatsheet of the apps, tricks and keyboard shortcuts I'm using, mostly for my own reference. Since keyboard-only use is also great for productivity, you may also find some of these ideas useful, in which case at least something good has come of this :)

Apps List

There's more detail on a few of these apps but here is a quick overview of the tools I've installed and found helpful
