'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.

Random Number Generation

Quote: “even if your RNG is statistically perfect, people will still complain 🙁 “
Another Quote: “On modern x86 CPUs, single core can generate 150M+ random bytes/second this way (and this is a Damn Lot).”

Implementing Queues for Event-Driven Programs

posted by

Quote: “full queues SHOULD NOT happen during normal operation”
Another Quote: “With queues-implemented-over-mutexes like the ones we’ve written above, the most annoying thing performance-wise is that there is a chance that the OS’s scheduler can force the preemptive context switch right when the thread-being-preempted-is-owning-our-mutex.”

C++ Guidelines – Made-to-Measure vs One-Size-Fits-All

posted by

Abstract: “After bashing all those Big Name guys for making those over-arching sets of guidelines, it is perfectly logical for me myself to do the same 😉”
Quote: “DON’T use C-style cast, EVER. If you DO need a cast – DO spend time on figuring out which of C++ *_cast<>s you really mean (and maybe, you’ll find a way to avoid that cast at all)”

C++ Performance: Common Wisdoms and Common “Wisdoms”

posted by

Quote: “over(ab)using C++ features is a different story, we’ll discuss these features below on case-by-case basis”
Another Quote: “Compiler will use all its Next-to-Divine Wisdom to show you that it is smarter than you are, and to ignore most of those inline specifications you carefully wrote.”

C++ for Games: Performance. Allocations and Data Locality

posted by

Abstract: “Allocations and related lack of spatial locality can be DAMN EXPENSIVE”
Quote: “During the times of Ancient Gamers (also known as times of Atari, ZX Spectrum, and Commodore64), CPUs were running at clock speed of a single-MHz (and one operation usually took several clocks). At the same time, memory run at about the speed comparable to that of CPUs.”

Marshalling and Encodings

posted by

Quote: “Encoded data size is especially important for Client-Server communications, and less important (within reason) for Server-to-Server ones and for locally-stored format.”
Another Quote: “On the other hand, due to being optimized for CPU operation, Flatbuffers are NOT optimized space-wise; even compared to not-so-optimal-space-wise Google Protocol Buffers, Flatbuffers can lose additional 1.5x in size”
