Slept well, although I went to bed a little late.

Supposed to be mid-eighties and rainy today. (Actually, it's blustering pretty seriously already!)

Went out with a bunch of people from work last night to celebrate Danielle's recent nuptials.

Goals:

    - Read about FreeBSD jails
      Yes, a little.
    - Work a little more on Pi thin client testing
      Yes, quite a bit.

Questions:

    - What would be involved in setting up our own Debian mirror?
      Too involved, and not the right solution. What we actually want is an apt cache server.

More Pi thin client notes (not super organized yet):

`visudo`
piadmin ALL=(ALL) NOPASSWD: ALL

Make sure ssh server is working.

Edit /etc/lightdm/lightdm.conf to enable autologin.

Edit ~/.xsession with:
    exec /usr/bin/startlxde

If Gnome is around:
    apt-get autoremove gdm3
    apt-get autoremove --purge gnome

Install:
x11vnc
freerdp-x11

xfreerdp -f --rfx --no-nla terminal.hartmantyner.com

Create ~/Desktop/Terminal_Server.shortcut file:
    [Desktop Entry]
    Name=Terminal Server
    Icon=/usr/share/icons/gnome/256x256/devices/gnome-fs-client.png
    Exec=/usr/bin/xfreerdp -f --rfx --no-nla terminal.hartmantyner.com
    Terminal=false
    Type=Application

Create ~/Desktop/Time_Clock.shortcut file:
    [Desktop Entry]
    Name=Time Clock
    Icon=/usr/share/icons/gnome/256x256/actions/appointment-new.png
    Exec=/usr/bin/iceweasel https://hartmanandtynerinc.attendanceondemand.com/ess/
    Terminal=false
    Type=Application

Create ~/Desktop/Emergency.shortcut file:
    [Desktop Entry]
    Name=Emergency
    Icon=/usr/share/icons/gnome/256x256/status/software-update-urgent.png
    Exec=/usr/bin/iceweasel http://emergency.hartmantyner.com/
    Terminal=false
    Type=Application

Hmm. The Pi doesn't have a power switch, so we probably don't want the user shutting it down. They may need to reboot once in a while though. ~/Desktop/Reboot.shortcut:
    [Desktop Entry]
    Name=Reboot
    Icon=/usr/share/icons/gnome/256x256/actions/reload.png
    Exec=/usr/bin/sudo /sbin/shutdown -r now
    Terminal=false
    Type=Application

`visudo`
piuser ALL=NOPASSWD:/sbin/shutdown

On the desktop, LXDE sorts icons by name, so we probably actually want to name our ~/Desktop/*.shortcut files like '00_foo.shortcut' and '01_foo.shortcut'.

Now, a vnc server...

Create the plain text file `/home/piuser/.vncpw`.
Prepend this to /home/piuser/.xsession:
    /usr/bin/x11vnc -display :0 -passwdfile /home/piuser/.vncpw &


Install conky. Add to /home/piuser/.conkyrc:

    background yes
    double_buffer yes
    update_interval 5
    total_run_times 0
    alignment top_right
    minimum_size 300
    text_buffer_size 1024
    own_window yes
    own_window_transparent yes
    own_window_hints below,undecorated,sticky,skip_taskbar,skip_pager
    border_inner_margin 10
    border_outer_margin 10
    gap_x 50
    gap_y 50
    use_xft yes
    xftfont DejaVu Sans Mono:size=12

    ${color white}${time %a %b %d %l:%M %p}

    ${color white}${exec /sbin/ifconfig | grep 'inet \addr' | head -1 | sed -e 's/.*addr:\(.*\) Bcast.*/IP Address: \1/'}

    ${color white}Uptime: ${exec awk '{printf("%d:%02d:%02d:%02d\n",($1/60/60/24),($1/60/60%24),($1/60%60),($1%60))}' /proc/uptime}

    ${color white}Load Avg: ${exec cat /proc/loadavg | cut -f1,2,3 -d ' '}

    ${color white}RAM $membar

    ${color white}CPU ${cpubar cpu0}

Add to /home/piuser/.xsession:
    /usr/bin/conky &

Set screen saver to blank screen only. ~/.xscreensaver

Edit /boot/grub/grub.cfg and set "GRUB_TIMEOUT=1".
