If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...

If you have a not-so-usual solution for your problems but need to justify it to your boss...

If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...

...then 'No Bugs' Hare on Soft.ware might be the right place for you.

Your mileage may vary. Batteries not included

Determinism: Requirements vs Features

posted December 26, 2016 by "No Bugs" Hare

Abstract:	Apparently, in practice there is big difference between cross-platform determinism and same-executable determinism, both in abilities they can provide, and from implementation complexity point of view
Quote:	“Cross-platform determinism is the strictest definition of determinism I know; not surprisingly, there are quite a few factors which can break it”

Quote:	“Then you can recover from any single server failure in a perfectly transparent manner”
Another Quote:	“after the program fails in production, we can get the input log and run it in the comfort of a developer’s machine, under a debugger, as many times as we want, and get exactly the same variables at exactly the same points as happened in production”

Quote:	“Yes, a coding architect might work (and is indeed orders of magnitude better than an architect who has no clue about the code), but a knowledge-sharing architect will generally work better.”
Another Quote:	“As a nice side effect, the very same knowledge sharing weakens a dependency on the architect (and reducing any dependency on a specific person is a Universally Good Thing™).”

Abstract:	The choice of TCP over UDP (or vice versa) might not always be obvious. In a sense, replacing TCP with UDP is trading off reliability for interactivity.
Quote:	“The most critical factor in selection of TCP over UDP or vice versa is usually related to acceptable delays”

Abstract:	“WHY are functional programming languages not popular for interactive programming purposes?” and “WHAT we can do about it?”
Quote:	“IMNSHO, deterministic Actors are the very best thing in existence for interactive programming, with lots of very practical benefits (from production post-mortem, to protection of in-memory state against server faults).”

Abstract:	Password hashing is a Big Headache, and doing it right is complicated
Quote:	“Note that none of the C++11 random number engines (LCG, Mersenne-Twister, or Lagged Fibonacci) can be considered good enough for cryptographic purposes – in short, they’re way too predictable and can be broken by a determined attacker, given enough output has leaked.”

Quote:	“However, the window for triviality is very narrow: for example, even going into two interrelated mutexes instead of one, can easily make multi-threading non-trivial”
Another Quote:	“Technically you are able to jump to any point of your program, but the variables you see may (and if you have a multi-threaded bug – will) differ every time you jump there.”
