l7-filter classifies packets based on patterns in application layer data. This allows correct classification of P2P traffic that uses unpredictable ports as well as standard protocols running on non-standard ports.
L7-filter is a classifier for the Linux Netfilter that identifies packets based on patterns in application layer data. This allows correct classification of P2P traffics. It can classify packets such as Kazaa, HTTP, Jabber, Citrix, Bittorrent, FTP, Gnucleus, eDonkey2000, etc., that uses unpredictable ports as well as standard protocols running on non-standard ports. It complements existing classifiers that match on IP address, port numbers and so on. http://l7-filter.sourceforge.net/.

PhoneGap is an open-source mobile development framework developed by Nitobi Software. It enables software programmers to build applications for mobile devices using JavaScript, HTML and CSS, instead of less-popular proprietary languages such as Objective-C. PhoneGap currently supports development for the iPhone, Palm WebOS, Google Android, Windows Mobile, Symbian OS and BlackBerry operating systems.
First developed at an iPhoneDevCamp event in San Francisco, PhoneGap went on to win the People's Choice Award at O'Reilly Media's 2009 Web 2.0 Conference.
The framework has been used to develop many apps, including one for Wine.com.
The framework has also been confirmed by apple to meet with its approval even with the new 4.0 developer license change.

"Nothing is Immune"
With PC Tools iAntiVirus™ you are protected against the most nefarious cyber-threats attempting to gain access to your Mac and personal information.
Once your computer has been infected, a virus or worm will usually attempt to spread itself to your friends, family and associates by accessing your email contacts and networked PCs. The infection may also allow hackers to access files on your Mac, use it to launch attacks against other computers and websites or to send mass SPAM email.
PC Tools iAntiVirus™ provides real-time protection and comprehensive system scanning to ensure your Mac remains safe and virus free.
Protection against Mac specific threats
The iAntiVirus™ database has been designed from the ground up to detect and remove Mac specific threats. This enables a high level of protection whilst keeping memory footprint and resource usage at a minimum. The iAntiVirus™ database is not cluttered with signatures for Windows specific threats which your Mac is immune against.
Simple to use
iAntiVirus™ has been designed with the user in mind. The user interface is purely functional, making it simple to scan for, remove and manage infections.

A variety of scan options You may perform a variety of scan types using iAntiVirus, this allows you to strike a balance between the time taken to complete a scan, and its thoroughness. Real-time protection IntelliGuard protects your Mac against infections in real time. Whenever an infection is detected and blocked, an alert is displayed below the system menu bar. IntelliGuard automatically places detected infections in quarantine, works silently in the background and uses minimal system resources. Quarantine iAntiVirus quarantines all detected infections, allowing you to easily view and restore items in the case of a false positive (for example: when scanning with engine heuristics set to high). Automatic Smart Updates Frequent updates to detect and guard computers against new threats and viruses as well as provide enhancements to iAntiVirus are automatically installed and downloaded through the Smart Update function. Threat signatures are updated within hours of a high risk malware outbreak to protect you from the latest online threats. Low resource usage When in monitoring mode iAntiVirus has been designed to work silently in the background, threats are blocked and removed without any system impact, while only a small alert window is displayed to advise you that your Mac has been protected against an attack.
