Firefox 3 Beta 4 is 5x faster than IE7, 3x faster than FF2

I had IE7 , Opera 9.26, and Mozilla Firefox 2. xx

any way, I received a news letter about Firefox 3 beta version.
I tried it , and i had the best experience ever with web browsers , it is even faster than they say!!

try it , Download Page

A new non-windows OS from Microsoft

This is mix of what i read on Microsoft  & ZDnet articles:

Singularity is an operating system and set of related tools and libraries that is developed completely in managed code. Singularity is not based on Windows; it was written from scratch as a proof-of-concept. Microsoft made the announcement at its Microsoft Research TechFest 2008 event in Redmond, Wash.
“We decided not to build operating systems that are built on technologies that are 30 years old,” said Principal Researcher Galen Hunt.

Singularity is a research project focused on the construction of dependable systems through innovation in the areas of systems, languages, and tools. We are building a research operating system prototype (called Singularity), extending programming languages, and developing new techniques and tools for specifying and verifying program behavior.
Because it was written in C#, Singularity is easier to analyze than other non-managed operating systems, the Microsoft researchers contend. Advances in languages, compilers, and tools open the possibility of significantly improving software. For example, Singularity uses type-safe languages and an abstract instruction set to enable what we call Software Isolated Processes (SIPs). SIPs provide the strong isolation guarantees of OS processes (isolated object space, separate GCs, separate runtimes) without the overhead of hardware-enforced protection domains.
Singularity uses these advances to build more reliable systems and applications. For example, because SIPs are so cheap to create and enforce, Singularity runs each program, device driver, or system extension in its own SIP. SIPs are not allowed to share memory or modify their own code. As a result, we can make strong reliability guarantees about the code running in a SIP. We can verify much broader properties about a SIP at compile or install time than can be done for code running in traditional OS processes. Broader application of static verification is critical to predicting system behavior and providing users with strong guarantees about reliability.



So now that the first release of Singularity is out, what will its developers do next? Singularity Version 2 — which will be focused primarily on heterogeneous, multicore computing environments, according to Lazrus and Hunt.
Modern and next-generation PCs and devices are moving to include different instruction sets and architectures on multiple cores. Microsoft has launched a number of projects focused on the forthcoming multicore revolution.
“We want to be able to access (all these cores) with the same programming model,” said Larus ” Think multiple Singularity kernels running on different cores.
“Singularity is a good place for researchers to (play with) changing the operating system,” said Research Area Manager James Larus.

Now, anyone can license the code (though it is primarily targeted at academics/researchers).
