These discs have the capacity to hold up to 3.9 TB of information, which is approximately 6,000 times the capacity of a CD-ROM, 830 times the capacity of a DVD, 160 times the capacity of single-layer Blu-Ray discs and about 8 times the capacity of standard computer hard drives as of 2006. The HVD also has a transfer rate of 1 gigabit/s. A 3.9 TB HVD could hold between 4,600–11,900 hours of video—just over one year of uninterrupted video.

Though still in the research stage, it employs a technique known as collinear holography, whereby two lasers, one red and one blue-green, are collimated in a single beam. However, Maxell is expected to release in September 2006 a disc with a capacity of 300 GB and transfer rate of 20 MB/sec.

While Microsoft talked up Windows Vista security at Black Hat, a researcher in another room demonstrated how to hack the operating system.

Microsoft has touted Vista as its most secure version of windows yet. Windows Vista has many layers of defense, including the firewall, running as a standard user, Internet Explorer Protected Mode, /NX support, and ASLR, which help prevent arbitrary code from running with administrative privileges.
However, Joanna Rutkowska, a Polish researcher managed to bypass the shield and get her code to work. This could be done only in the administrator mode.

Though released long time back, I havent heard many people talking about it.
The Windows Desktop Search is MUCH MUCH BETTER than GOOGLE DESKTOP SEARCH. For starters it scans a lot more files on your hard disk and you can also search for a specific type of file. And if you are also like me who uses outlook express, then no more waiting to search for your messages! Besides, it also has add-ins one of them which also lets you search for .pdf files on your computer. And not to forget, it also has a Preview Pane, which lets you view the file without opening it. And all this within a second(speed of google). Obviously it takes time to index all the files but i guess its worth it in the end if you have a huge hard disk and totally detest the search embedded with your OS.

I also remember a discussion happening on this blog – Internet Explorer vs Firefox
and one of the major reasons that firefox won the battle besides the security factor was “Tabbed Browsing”. But guess what, interent explorer also provides you that now.
