Windows Earlier today, OSNews ran a story on a presentation held by Microsoft's Eric Traut, the man responsible for the 200 or so kernel and virtualisation engineers working at the company. Eric Traut is also the man who wrote the binary translation engine for in the earlier PowerPC versions of VirtualPC (interestingly, this engine is now used to run XBox 1 [x86] games on the XBox 360 [PowerPC]) - in other words, he knows what he is talking about when it comes to kernel engineering and virtualisation. His presentation was a very interesting thing to watch, and it offered a little bit more insight into Windows 7, the codename for the successor to Windows Vista, planned for 2010.

Is ext4 128 bits? I tend to think that's excessive, but maybe you might have virtual drives composed of several physical ones and it might prove convenient to use high bits for physical drive number, or if they were on a network, include numbers for that. I picked 64-bits for my filesystem, but I can see reasons for 128.

No. (Can you *imagine* the ruckus on LKML if anyone proposed such a thing?!) But the current ext3 filesystem size limitation is only about 16 terabytes, depending on architecture. It does not take full advantage of 64 bit. Ext4 raises that to an exabyte. And adds extents, as well. But that's tangential.
