In the course of six months IMVU’s user base quadrupled in size. At the start of this period we were bottlenecked on a single central database. During these six months we evolved IMVU’s architecture to use caching with memcached, replication, horizontal and vertical partitioning to support this growth. We’ll look …
Design Patterns must be studied in the context on the language in which they’ll get implemented.

This talk explores several categories of classic “elementary” DPs in a Python context …

Modeling is not the preserve of plan-driven methods, and the problems sometimes encountered lie not with modeling per se but with overdosing on models and failing to use modeling as an opportunity for communication. Models that become an end in themselves and are drawn up by individuals in isolation from …
Ruby’s success in several domains is arguably due to domain-specific languages (DSLs) that generate code: we have tools that generate HTML, CSS, and Javascript, and so we get to write web applications in ruby; ditto SQL and database applications. There are some less well known examples in the simulation and …
Most Ruby programmers have a mental model of how Ruby manages objects and classes. But the chances are good that this model is more complicated that it should be. Come and see how simple Ruby really is; a couple of simple concepts cover all you need to know. Once you …
