Nothing interesting about me. This is not the user you are looking for. Move along. Move along.

This might have worked, except that this laptop model does not have a SysRq key, believe it or not.

comment How to force power-off of a Samsung Series 9 laptop?
Definitely not a motherboard issue because after rebooting (it did run down), it works again. Seems to be a pure software issue, except for the fact that the 4-second power cutoff is supposed to be hardware only, not software.

comment How to mess up a PC running Windows 7?
@nhinkle: I got the idea that he meant setting the BIOS overheat limits to something low like 50 C, not actually overheating anything.

comment How important is having 64-bit programs on 64-bit OS?
@Joshua: System drivers really depend on the OS and the machine arch. Some 64-bit CPUs don't have modes, just added 64-bit instructions. x86_64 has an expensive mode switch to get from 64 to 32 and back, so drivers are almost always required to be 64-bit.

comment Limiting CPU speed in a virtual machine?
Yeah, this could have a real bad effect on timing loops. It all depends on if it runs full speed up to 45% then cuts out, or if it tries to actually run at 45%.

comment Which TAR to install - IA-64 or X86 64bit?
Not exactly "mainframe." I've got two Itanium systems, one is 4U the other is 1U. Got them off eBay.

comment SandForce SSD encryption - security and support
The full-disk encryption slowdown only applies to Sandforce controllers which rely on compression for their speed.

comment Compress and then encrypt, or vice-versa?
@AbiusX: Right. Patterns. And the fewer patterns, the more entropy. Which means that compression which replaces all repeated patterns with a single copy increases entropy.

comment Compress and then encrypt, or vice-versa?
But it is information entropy so it is all about meaning. Randomness doesn't mean anything so it doesn't apply. An English sentence can have letters changed and still mean the same thing so it has low entropy. A compressed English sentence might be unreadable if a single bit changes so it has the most. Or so I think.

Wait, don't you have that backwards? I thought entropy increased as redundancy decreased. Therefore compression should increase entropy.

comment Why aren't all applications 'portable'?
Exactly. How could the OS find the EXE or DLL to load without a fixed location? "Set oExcelApp = CreateObject("EXCEL.APPLICATION")" needs to work somehow.

Big speakers would also erase your credit cards if you set a wallet on one. :-)

Network latency alone will prohibit true millisecond accuracy.
