Inside NGINX: How We Designed for Performance & Scale
NGINX leads the pack in web performance, and it’s all due to the way the software is designed. Whereas many web servers and application servers use a simple threaded or process‑based architecture, NGINX stands out with a sophisticated event‑driven architecture that enables it to scale to hundreds of thousands of concurrent connections on modern hardware. The NGINX Architecture infographic drills d

Go in Go Gopherfest 26 May 2015 Rob Pike Google Go in Go As of the 1.5 release of Go, the entire system is now written in Go. (And a little assembler.) C is gone. Side note: gccgo is still going strong. This talk is about the original compiler, gc. 2 Why was it in C? Bootstrapping. (Also Go was not intended primarily as a compiler implementation language.) 3 Why move the compiler to Go? Not for va

JavaScript Application Architecture On The Road To 2015
I once told someone I was an architect. It’s true in a way since I now have to design an intricate web of lies to back it up. On a serious note, I thought it might be salutary to look at the state of application architecture in the JavaScript community as we ebb our way towards 2015. I’ll talk about composition, functional boundaries, modularity, immutable data structures, CSP channels and a few o

The Architecture of Open Source Applications
Architects look at thousands of buildings during their training, and study critiques of those buildings written by masters. In contrast, most software developers only ever get to know a handful of large programs well—usually programs they wrote themselves—and never study the great programs of history. As a result, they repeat one another's mistakes rather than building on one another's successes.
