Disclosure: On this site you won’t find specific advice on “how to call function xyz()”. Interpreting C++ ARM and #pragma dwim is also out of scope.

We’re treating our readers as intelligent beings who can use Google and/or StackOverflow, where all such specific questions were answered more than once.

What you will find is opinions, more opinions, and even more opinions on all the aspects of software development - and with a large chunk of them based on real-world experience too.

MMOG. RTT, Input Lag, and How to Mitigate Them

January 25, 2016 by “No Bugs” Bunny

The game of Client-Server

Quote:

For fast-paced games, there is one big problem with the flow shown on this diagram, and the name of the problem is “latency” (a.k.a. 'input lag')

Another Quote:

No, better bandwidth doesn't necessarily mean better latency

MMOG Server-Side. Programming Languages

January 18, 2016 by “No Bugs” Bunny

C++ sitting on two chairs

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)

Asynchronous Processing for Finite State Machines/Actors: from plain event processing to Futures (with OO and Lambda Call Pyramids in between)

January 11, 2016 by “No Bugs” Bunny

Juggling with Futures

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

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

January 4, 2016 by “No Bugs” Bunny

Linux-vs-Windows Armwrestling

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%).
