An absurdly clever thermal imaging camera. Upside-Down-Ternet. My neighbours are stealing my wireless internet access. I could encrypt it or alternately I could have fun. I'm starting here by splitting the network into two parts, the trusted half and the untrusted half. The trusted half has one netblock, the untrusted a different netblock.
We use the DHCP server to identify mac addresses to give out the relevant addresses. /etc/dhcpd.conf IPtables is Fun! Suddenly everything is kittens! /sbin/iptables -A PREROUTING -s 192.168.0.0/255.255.255.0 -p tcp -j DNAT --to-destination 64.111.96.38 For the uninitiated, this redirects all traffic to kittenwar. For more fun, we set iptables to forward everything to a transparent squid proxy running on port 80 on the machine. /sbin/iptables -A PREROUTING -s 192.168.0.0/255.255.255.0 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.0.1 That machine runs squid with a trivial redirector that downloads images, uses mogrify to turn them upside down and serves them out of its local webserver. The redirection script.

Change the Windows 7 Login Screen Background Image. When you login to your Windows 7 computer (assuming you haven’t used something like this tutorial to turn on automatic login), you’ll generally see a login window with a background looking something like this.
It’s fine; there’s nothing wrong with it. But sometimes a change is good so in this article we’ll show you how to change the background image behind the login screen to anything you want. The first step is to open up the Start Menu by clicking the orb in the lower left corner of the screen. Now, in the Start Menu search box, type regedit, to open up the Registry Editor.
When the Registry Editor appears in the Start Menu, click the Enter key to launch it. Now, right-click on the HKEY_LOCAL_MACHINE folder, and choose the Find option. The search window will appear so perform a search for OEMBackground. Note: it’s possible that OEMBackground doesn’t exist on your system; if this is the case, adding a new DWORD value with the name of OEMBackground will fix things.
