On.Programming
For most of us, programming (or more generally – software development) is all the life is about.
IT Hares are not different. And they have more than just quite a few bits to share about programming…
Size Matters - Is 64-bit App Always Better?
May 1, 2014 by • “No Bugs” Bunny
Abstract:
Sometimes it makes perfect sense to use 32-bit application on 64-bit platform.
Quote:
It is obvious that for N between 13,000,000 and 21,000,000, 64-bit application works about 1000x slower.

September 1, 2013 by • “No Bugs” Bunny
Abstract:
Speed of light imposes hard limits on possible latencies of high-volume RAM
Quote:
Even if each bit is implemented by single atom of silicon, 2^90-byte RAM is the largest RAM which can possibly have latencies comparable to modern DDR3 SDRAM.
