Nice article by CloudFlare with a video of Syria turning off the internet for the country.
CDNet on how Egypt did the same thing.
Bit of security, bit of privacy, and a bit of Kami

I teach a class on Processing, which is a simplified version of Java designed to enable people to easy create graphics. My class focuses on data visualization. Below is my list of publicly available data sets which I encourage my students to use in their visualizations.
IMDB is a website that maintains a list of movies, actors, actresses, and information about them. They offer a set of downloadable information sets. The sets can be a bit challenging to parse though, so there also exists some Perl parsing scripts.
StackOverflow has a list of publicly available data sets.

Sony Hotkeys Utilities (SOAOTH-606A0000-0042.exe) disables User Account Control (UAC) on my Windows 7 machine.
After re-installing Windows 7 on my Sony laptop I wanted to make my hotkeys (like volume) work again so I installed the Hotkeys utility by Sony. A few weeks later I got suspicious when several programs I opened had “Administrator:” in the title when I hadn’t approved any UAC. I checked my logs and the last program to ask for privilege elevation was the Hotkey utility.
I re-enabled UAC dialogs and re-booted the machine. I re-downloaded the utility from Sony, installed it, and was asked to approve a UAC dialog (so UAC was definitely enabled). Sony software asked that I reboot the machine to “finish installation.” Immediately after the Sony dialog appeared a balloon in the bottom right appeared with the following text: “You must restart your computer to turn off User Account Control.” Sony’s software was the only thing running and I hadn’t opened any User Account Control settings since restarting the computer.
I let the software reboot the computer. After the reboot Sony software continued to install itself. I opened the User Account Control settings panel and verified that UAC was disabled.
Sony’s software finished installing itself, theoretically requiring UAC to do so, and asks to reboot a second time. I allowed it to reboot the machine and after the second reboot I pulled up the UAC settings again to verify that they were still disabled. As can be seen below the settings stayed with UAC disabled after two reboots.
Turning off UAC dialogs without user notification is a very dangerous thing to do. My computer spent several weeks in a state where any program that wanted to install could just do so without my approval. My programs were running with “Administrator” in the title because they were running with Administrator privileges (I manually verified this for PowerShell). No well behaved software should ever change security settings on a computer without notifying the user.
A couple of limitations to consider
