Everyone who uses Firefox should be excited about Jetpack, a new, experimental project from Mozilla Labs that allows developers to extend and enhance the browser in novel and exciting ways. Content producers, on the other hand, might not be so thrilled.
Firefox already has a thriving add-on community, with more than 1,000 third-party extensions available now. But so far, developing add-ons for Firefox meant you had to learn XUL, the Mozilla Project's XML-based UI language. Jetpack will further simplify the development of add-ons because it makes possible building new ones using familiar, open, Web standard technologies, including HTML, JavaScript, and CSS.

With just a few lines of code, developers can use Jetpack to add information to the status bar, create mashups, and manipulate the content and presentation of Web pages -- and they can do so using the languages they already know. That's an exciting development because it brings us one step closer to a truly democratic Web.
Free Software advocate Richard Stallman believes that SaaS and cloud computing applications are dangerous, because they force users to hand over control of their computing to whomever is running the server. "It is like running binary-only software," he says, "only worse: It's even harder for you to patch the program that's running on someone else's server than it is to patch a binary copy of a program running on your own computer."
With Jetpack, however, you can patch the server, in a sense. You can't actually change the program running on the server, but you can change the behavior of the program to your liking. You can modify its output, filter it, change its presentation, and even combine it with additional data sources and new layers of computation. You can even discard some portions of the server's output if you want.
That's great for developers and for users. But it's not so great for the SaaS providers and media companies that have a vested interest in controlling the function, presentation, and distribution of their Web-based content and applications.

A common misconception is that mid-range storage requirements are dramatically different than that of a larger enterprise. Mid-range storage users may require less capacity, but they have similar functionality and management requirements. This ESG paper examines mid-range storage needs and reviews a new solution that adjusts size while retaining value, performance and functionality.

...with President Obama due to announce a "cybersecurity czar" this week, there is every indication that the U.S. government is ready to become more directly involved in the workings of the Internet and the Web
What a dubious claim!
Where have you seen any indication that this new chair in the US government is going to have anything to say about The Web? I don't believe there is even a single hint that web technologies such as HTTP, HTML, CSS, DOM, Javascript, etc. will have much of anything to do with this person's job, except to advise what sort of web software should be installed and used in government facilities. Maybe this person will issue the CERT when the day comes that a vulnerability Flash or MSIE is used to launch a DDOS attack, but that is as close as it gets.
Are you just making this stuff up?
