The syntax for the rename command is:
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
-v means “verbose” and it will output the names of the files when it renames them. It is a good idea to use this feature so you can keep track of what is being renamed. It is also a good idea to do a test run with -n which will do a test run where it won’t rename any files, but will show you a list of files that would be renamed.

Every computer running Windows that has the file sharing component installed and enabled on a network interface broadcasts a periodic (every 12 minutes) Host Announcement message on the local subnet. On the master browse server for the subnet, these messages are used to maintain the list of available servers in the browse list

This is a very noisy service — especially on a network that doesn’t care about browser services.
PolarSSL makes it easy for developers to include cryptographic and SSL/TLS capabilities in their embedded products with as little hassle as possible. It is designed to be readable, documented, tested, loosely coupled and portable.
via Light-weight, modular cryptographic and SSL/TLS library – PolarSSL.
I found the above site from this article on Slashdot.
The major change is the removal of OpenSSL as the cryptographic core of OpenVPN-NL. Instead, the Dutch government opted to include the smaller, better readable and documented open source library PolarSSL to provide the cryptographic and SSL/TLS functionality.
The Corosync Cluster Engine is a Group Communication System with additional features for implementing high availability within applications. The project provides four C Application Programming Interface features:
Our project is used as a High Availability framework by projects such as Apache Qpid and Pacemaker.
We are always looking for developers or users interested in clustering or participating in our project.
The project is hosted by Fedora Hosted and the The Linux Foundation.
In the near term, though, garnet-on-silicon chips are likely to be used in networking — first in backbone routers, which are physically huge and very power hungry because of the current size of optical switching hardware, and then hopefully at home and in the office (100Gbps home networks!) Then, once the size of MIT’s diode for light is scaled down — it’s currently around 400nm long, some 20 times larger than a transistor — we might begin to see photonic circuits in computers.

Growth will slow to double digits beginning in 2012, but the number of users will rise to nearly 90 million, or 35.6% of all internet users, by 2014.
A5/1 is a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard. It was initially kept secret, but became public knowledge through leaks and reverse engineering. A number of serious weaknesses in the cipher have been identified.

Masquerading Made Simple HOWTO.
Masquerading must be put in the NAT chain or the router won’t know how to return packets to subnets other than its own LAN.
The Top 10 Supercomputers, Illustrated, Nov. 2011 » Data Center Knowledge.
The twice-a-year list of the Top 500 supercomputers documents the most powerful systems on the planet. Many of these supercomputers are striking not just for their processing power, but for their design and appearance as well. Here’s a look at the top finishers in the latest Top 500 list, which was released Monday, November 15, 2011 at the SC11 conference in Seattle.
