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.

But when I first read the this, I read no one will ever need more than 64 bit for a software. ;) Is it possible that saying, we don't need it is too short sighted or arrogant?


Never say never. And, of course, 40-60 years is not never. ;-)

But I don't *think* I'm being short sighted. The 20th century conditioned mind thought in terms of arithmetic progressions with regards to computer hardware and was continually underestimating future requirements. The 21st century conditioned mind is used to thinking in terms of geometric progressions. And the geometric constants for the increase in disk space, ram, and transistor density in processors have remained remarkably constant over the 20 years I have been watching. If anything, I would expect the constants to *decrease* over the years.

At any rate, and for now at least, one can figure 1 bit for every two years on memory, and 1 bit for every year and a half of disk.

X86_64 took us from 32 bits to 48 bits for memory addressing. A difference of 16 bits. So I figure we're good for 32 years. In fact, due to the way X86_32 works, one has to start making tradeoffs at less than 1GB. Not sure if and where such tradeoffs might need to be made with current processors.

I'm sure some kind soul will stop by to fill us in on that.
