 ==Prompt==
 
+I originally built my prompt using http://bashrcgenerator.com and, while it's a nice tool for visually building a prompt, it has several limitations on what you're able to create with it. But more importantly to me, it generates a rediculously long string, defines and resets color for every single character, uses both a color and bold escape sequence to use light/bright colors, mixes raw escape sequences and subshells running tput, and as a result is utterly unreadable and unmaintainable.
+
+So, I replaced it:
+
+{{{class="prettyprint"
+### PROMPT ###
+
+promptsetup() {
+	# Color definitions for prompt
+	local fg_brightred='\[$(tput setaf 9)\]'
+	local fg_blue='\[$(tput setaf 4)\]'
+	local fg_magenta='\[$(tput setaf 13)\]'
+	local fg_cyan='\[$(tput setaf 6)\]'
+	local fg_brightcyan='\[$(tput setaf 14)\]'
+	local reset='\[$(tput sgr0)\]'
+
+	# [hh:mm][username@hostname pwd]$
+	if [ -n "$SSH_CLIENT" ]; then
+		# Remotely, hostname is red.
+		PS1="${fg_blue}[\A]${fg_cyan}[${fg_brightcyan}\u${fg_cyan}@${fg_brightred}\h ${fg_cyan}\W]${reset}\$ "
+
+	elif [ -n "$VCSH_REPO_NAME" ]; then
+		# If in a vcsh repo env, add repo name in magenta.
+		PS1="${fg_blue}[\A]${fg_cyan}[${fg_brightcyan}\u${fg_cyan}@\h ${fg_magenta}$VCSH_REPO_NAME ${fg_cyan}\W]${reset}\$ "
+
+	else
+		# Locally, hostname is cyan.
+		PS1="${fg_blue}[\A]${fg_cyan}[${fg_brightcyan}\u${fg_cyan}@\h \W]${reset}\$ "
+	fi
+}
+
+promptsetup
+}}}
+
+I intentionally put everything in a function and call it immediately so I may use local vars for the color definitions. I didn't really want to leave them around just in case.

 ==Profile==
 
+Bash chooses which dotfile to source based on how it gets run. If starting from a login shell, `~/.bash_profile` will get sourced, but if there's not a command in there to source your `~/.bashrc`, you may find yourself having to `exec bash` after starting bash. This can be fixed by adding the following line to your `~/.bash_profile`:
+
+{{{class="prettyprint"
+[[ -f ~/.bashrc ]] && . ~/.bashrc
+}}}
+
+I also use `~/.bash_profile` for setting numlock while in a tty:
+
+{{{class="prettyprint"
+case $(tty) in /dev/tty[0-9]*)
+	setleds -D +num # (numlock for X is set in ~/.xinitrc)
+	;;
+esac
+}}}
+
+The last thing of note in my `~/.bash_profile` is a warning:
+
+{{{class="prettyprint"
+	# Temporary fix for a systemd bug related to systemd --user timers that run on login
+	[[ -z "$DBUS_SESSION_BUS_ADDRESS" ]] && printf "%bWARNING: \$DBUS_SESSION_BUS_ADDRESS is unset! %b\n" "$(tput bold)$(tput setab 1)" "$(tput sgr0)"
+}}}
