comment Processor Multimedia Extensions. How Useful are they actually?
@Doc Thanks. All the wikipedia articles on the extensions describe the new op-codes and the implementation details beautifully, but not one mention of who actually uses this stuff. MMX is one of those that has been around long enough that I'm sure you can assume everyone has it..

comment Lenovo ThinkPad400s screen cracked. Warranty expired. What are my options?
+1 for ebay replacements, its cheap and easy to do especially on lenovo's/ibm. Reliability really depends on the model line, The T40's for instance were solid machines, but suffered from extreme motherboard flex that would slowly kill them for 6 months (the problem started usually 3-4 years down the line)

comment What is the oldest Windows operating system to run on a modern (2007-2009) computer?
ALl modern CPU's by intel and AMD still have real mode (a 16 bit mode with no virtualization still required by BIOS). And are technically backwards compatible with the 286 real mode and thus will run Windows 2.0, However the rest of the hardware may not be so nice, in particular the memory controller and the IDE controller, not to mention support for PCI is lacking in old systems (and ISA has been absent from motherboards for almost a decade now).

Another advantage is that you can easily migrate it between different computers (Hosts), especially if the disk image is small (say 512MB for an ancient dos system).

comment Why does my 32bit ubuntu see 8GB of RAM?
All your applications still see a 4GB virtual address space (rather than a 2 exabyte virtual address space with 64 but applications) - even AFAIR the kernel itself. Only the memory manager is aware of the larger physical memory. In some ways PAE is more efficient, there is some translational overhead, but the memory overhead of 32 bit processes is less than that of 64 bit addresses, the memory needed to store a full 64 bit page table is effectively 4 times that of a 32bit page table. While multi-tasking is popular (and thus the demand for big RAM), very few applications hit the 32bit VA limit
