Reducing the maximum latency of a bound buffer in Erlang
Recently I came across two great articles on the Pusher blog: Low latency, large working set, and GHC’s garbage collector: pick two of three and Golang’s Real-time GC in Theory and Practice . The articles tell the story of how Pusher engineers reimplemented their message bus. The first take was done in Haskell. During…

Why is .NET reflection slow?
It’s common knowledge that reflection in .NET is slow, but why is that the case? This post aims to figure that out by looking at what reflection does under-the-hood.

Beating the Compiler
An oft-repeated fact on programming forums these days is that a decent optimizing compiler will always beat a puny human's attempt at hand-written assembler. There are rare cases, like MPEG decoders, where making good use of the SIMD instructions can allow assembly to massively beat the compiler. But generally you'll…

Learning to Read X86 Assembly Language
Writing assembly language is something best left for the experts. To write code that runs directly on your microprocessor you need to know how memory segmentation works, what the intended use of each register is, how codes executes in real and protected modes and much, much more. And, of course, modern compilers will…
