Requirement Analysis - IT Hare on Soft.ware

The Importance of Back-of-Envelope Estimates

Quote:

“trying to optimize out a 3e-7 performance hit is very rarely worth the trouble.”

Another Quote:

“With 4S/4U boxes having typical MTBFs of 3–5 years, the next question we should ask ourselves, is “Hey, will we really be able to write software which crashes much more rarely than that?””

MMOG Server-Side. Eternal Linux-vs-Windows Debate

Quote:

“Each server is only as secure as its admin”

Another Quote:

“For cheaper servers, the difference between Windows and Linux can eat as much as 50% of the server rental price (though for those servers which are more or less optimal price-performance-wise observed difference was closer to 20-30%).”

MOG GDD (a.k.a. Business Requirements)

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.”

Size Matters – Is 64-bit App Always Better?

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.”

Hard Upper Limit on Memory Latency

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.”

640K 2^256 Bytes of Memory is More than Anyone Would Ever Need Get

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.”

Intellectual Property – a Crash Course for Developers

Abstract:

Copyrights, patents, trademarks, and licenses explained for software developers.

Quote:

“The first de-facto trademarks appeared when a blacksmith in a small town decided to put a special sign on his swords…”
