Qualsys Security Labs researcher Sergey Shekyan has created a proof-of-concept tool that could be used to essentially shut down websites from a single computer with little fear of detection. The attack exploits the nature of the Internet's Transmission Control Protocol (TCP), forcing the target server to keep a network connection open by performing a "slow read" of the server's responses.
The Slow Read attack, which is now part of Shekyan's open-source slowhttptest tool, takes a different approach than previous "slow" attacks such as the infamous Slowloris?a tool most notably used in 2009 to attack Iranian government websites during the protests that followed the Iranian presidential election. Slowloris clogs up Web servers' network ports by making partial HTTP requests, continuing to send pieces of a page request at intervals to prevent the connection from being dropped by the Web server.
Slow Read, on the other hand, sends a full request to the server, but then holds up the server's response by reading it very slowly from the buffer. Using a known vulnerability in the TCP protocol, the attacker could use TCP's window size field, which controls the flow of data, to slow the transmission to a crawl. The server will keep polling the connection to see if the client?the attacker?is ready for more data, clogging up memory with unsent data. With enough simultaneous attacks like this, there would be no resources left on the server to connect to legitimate users.
Shekyan said in his post about the tool that this type of attack could be prevented by setting up rules in the Web server's configuration that refuse connections from clients with abnormally small data window settings, and limit the lifetime of an individual request.

iPad: CloudOn brings a fully-loaded version of Microsoft Office to the iPad, so you can edit documents on-the-go using all of Office's features, and store your documents right in your Dropbox. 
CloudOn isn't really a touch-optimized version of Office; instead, it's like using a screen-sharing app with a computer running Office elsewhere. You'll need an internet connection to use it, since the program runs on CloudOn's servers, but it actually works pretty well, despite being designed for a mouse and keyboard. You probably wouldn't want to do all your document editing from it, but for quick edits, tracking changes, or reviewing presentations, it's really useful, and doesn't have the compatibility problems that might come with something like iWork. It also stores all your documents in your Dropbox, so you have easy access to them everywhere you go.
