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.

Quote:	“From the 50’000-feet point of view, 90% of the differences between modern mainstream programming languages (as they’re normally used – or better to say, SHOULD be used – at application-level) are minor or superficial.”
Another Quote:	“On the server side (unlike client-side) protection from bot writers is not an issue (as server-side code is never exposed to players)”

Quote:	“With ‘callback pyramid’ it is not easy to express the concept of ‘wait for more than one thing to complete’ , which leads to unnecessary sequencing, adding to latencies (which may or may not be a problem for your purposes, but still a thing to keep in mind).”
Another Quote:	“Don’t even think of converting all of your code to a so-called Continuation-Passing-Style”

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%).”

Quote:	“If you disrupt the game-event-currently-in-progress for more than 0.5-2 minutes, for almost-any synchronous multi-player game you won’t be able to get the same players back, and will need to rollback the game event anyway.”
Another Quote:	“However, keep in mind, that all fall-tolerant solutions are complicated, costly, and for the games realm I generally consider them as an over-engineering (even by my standards).”

Quote:	“After your logic has failed in production, you can “replay” this inputs-log on your functionally identical in-house system, and the bug will be reproduced at the very same point where it has originally happened.”
Another Quote:	“You can implement your Finite State Machine as a deterministic variation of a usual event-driven program”
