'No Bugs' Bunny

Once upon a time, in a rabbit outsourcing warren of Bunnylore, there was a young software developer bunny. And as a developer, he has had one very unusual treat: he was obsessed with eliminating all the bugs he can get his forelegs on. So, it is not surprising that his friends called him a “No Bugs” Bunny (or simply “NoBugs”).

Later on, he grew up, so he decided that “Bunny” in his name has became inappropriate (not to mention potential arguments with Warner Brothers), so he has asked all his friends to call him “No Bugs” Hare. He has made a career as a team lead and software architect, and they lived happily ever after.

“No Bugs” Hare Opera Omnia, Vol.22:

MMOG. Point-to-Point Communications and non-blocking RPCs

posted by

Quote: “In other words, you can write your code ‘as if’ all-your-code-within-the-same-FSM executed within the same thread”
Another Quote: “As soon as we have these two parts of processing – we can say that our Server-to-Server communication is tolerant to all kinds of transient inter-server disconnects”

MMOG: World States and Reducing Traffic

posted by

Quote: “In practice, for most classical RPGs you can get away with simulating each of your PCs and NPCs as a box (parallelepiped), or as prism (say, hexagonal or octagonal one)”
Another Quote: “Mathematically speaking, without Interest Management, the amount of data on our servers will need to send (to all players combined), is O(N^2). Interest Management reduces this number to O(N)”

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

posted by

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

posted by

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)

posted by

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

posted by

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%).”

Server-Side Architecture. Front-End Servers and Client-Side Random Load Balancing

posted by

Quote: “[about Round-Robin DNS] one of these returned IPs can get cached by a Big Fat DNS server, and then get distributed to many thousands of clients”
Another Quote: “As a rule of thumb, Front-End Servers are a Good Thing™”
