# UFW configuration for a home DMZ box exposed to the public internet, with only sshd reachable from the outside world.
# In addition to setting these rules you should also:
# 1. Edit /etc/ufw/before.rules to remove the default rules which permit incoming DHCP packets from the outside world.
# 2. Edit /etc/ufw/before.rules to remove the default rules which permit incoming ICMP packets from the outside world.
# 3. Edit /etc/default/ufw to turn off non-local ipv6 because I don't know enough about it to be confident.
ufw default deny incoming

By default, Debian only colorizes bash output for regular users. Rather than copy your ~/.bashrc to /root, take just take it out and have /etc/bash.bashrc source this instead.
# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then
debian_chroot=$(cat /etc/debian_chroot)
# set a fancy prompt (non-color, unless we know we "want" color)

Aliases for code reviewing GitHub pull requests using a GitFlow/OneFlow branching model
View git-review-aliases.txt
The code review workflow that I prefer is to check out a feature branch, then `reset --soft` to move the branch HEAD to
just before the changes. That way I still have all of the changes in my working copy, and those exact changes are staged
for commit. My IDE will highlight the changed lines right in the editor and let me click the gutter to view a quick diff.
This is incredibly useful. But problems arise when develop has been merged into a running PR, bringing along a whole bunch
of other unrelated changes that have already been reviewed. I don't want all of those other changes to be highlighted in
my IDE, but I do want them in my working copy.
