krb5_newrealm doesn’t seem to add enough lines to /etc/krb5.conf. To fix this, add the following lines to /etc/krb5.conf on all machines participating in the realm. My local realm is LAN, but substitute your own. The new lines will be in bold, the existing lines should already exist, if they don’t, add them.
[realms]
LAN = {
kdc = infinity.lan
admin_server = infinity.lan
default_domain = lan
}
[domain_realm]
.lan = LAN
lan = LAN
All hosts/servers participating in the realm that offer Kerberized services should have a FQDN that ends in your realm’s domain name (.lan in my case).
XFCE is a GTK2 environment, however a lot can be done to improve GTK3 apps on XFCE.
I prefer to use Clearlooks as my GTK2 theme and use the GNOME icon set. On Debian, apt-get install gnome-icon-theme gnome-icon-theme-extras gnome-icon-theme-symbolic clearlooks-phenix-theme and use the XFCE Appearances to change your theme to Clearlooks-Phenix and your icons to GNOME.
If you’re using an XFCE GTK engine theme instead, install gtk3-engines-xfce instead of clearlooks-phenix-theme, and there also is a gtk3-engines-oxygen which provides a native look-alike of KDE4’s Oxygen theme.
You probably should restart your X session after fiddling around with this to fix apps that don’t change themes at runtime properly.
Some people think the sub-pixel color fringing is too strong when they have sub-pixel anti-aliasing on. If your install is old enough, you might not have the correct symlinks in /etc/fonts/conf.d. Do…
sudo ln -s /usr/share/fontconfig/conf.avail/11-lcdfilter-default.conf /etc/fonts/conf.d/
… and restart X. This should fix the problem.
First, I’d like to say congratulations to NASA on the landing of Curiosity. It was worth every dollar of that $2 billion.

Apparently there is no dead simple way to send audio from one computer to another in a low(er) latency way.
Can’t beat this, works for any ALSA app that you can change the output for (or just change your default in .asoundrc).
On source computer:
modprobe snd-aloop
arecord -f cd -D hw:Loopback,1,0 | netcat dest 1234
mplayer -ao alsa:device=hw=Loopback.0.0 something.mp3
On destination computer:
netcat -k -l -p 1234 | aplay
Update: Oh, and apparently you can do this in Windows, too.
