Re:Importance of 64-bit architectures

Intel's Big Chip

A real problem this time around is that the C language and its relatives really do like 32-bit integers, and many of the Unix system calls also assume 32 bits. If you make the native int/pointer sizes 64 bits, there's a lot of stuff that will probably break. What kind of experience have people had running code on DEC Alphas and other real-64-bit chips?
How much do you have in writing *nix code?
Unix programmers should know better than to assume about the size of types except the fixed size types as int32_t that are avaliable in any *nix system. Unless we screw up of course.
The manual refers to the journaling feature.
In a journaling file system, structures/data are journaled instead of immediately overwritten. If the systems crashes during while writing, its likely you can at least revert to a previous, coehrent, state of the filesystem, instead of being stuck with a corrupted filesystem.
Though the effect of this behavior is more or less limited, it should be enough to worry anyone who thinks about using shred.
I'm not sure but I think DDR-SDRAM should have half the latency as tradicional SDRAM.
They have more or less the same architecture but DDR-SDRAM tranfers two bits per cycle while SDRAM only tranfers one.
RDRAM also transfers two bits per cycle but has a completly diferent architecture.
