Quote:
You don’t “make” a violin. It is barrels and benches which are “made”. And violins, just like bread, grapes, and children – are born and raised.
Another Quote:
The very first step should be to understand what exactly you're going to achieve.

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.

January 1, 2013 by • “No Bugs” Bunny
Abstract:
Physics imposes hard limits on amount of memory we will get in foreseeable future.
Quote:
Even if every memory cell can be represented by a single atom, we would need 1 to 10% of all the stars and planets which we can see , to implement 2^256 bytes of memory.
