How We Found a Missing Scala Class

Here’s a fun tale of debugging that starts off with a common alert nagging our on-call rotation, leads us to a very confusing NoClassDefFoundError, and ends up with us knowing a lot more about dynamic tracing in the JVM.

Scala Programming - A Skeptic's Journey

While Scala has much to offer that I won’t cover (e.g., type classes and functional programming constructs for managing side-effects), I think it is useful to consider what are those things that are most accessible to developers coming from a Java/C++ ecosystem.

PRESENTATIONS

Homegrown Scala Collections - Part 5 - Linked Set

In this video we are going to revamp our initial implementation of Sets, since it offered no way to link elements of a Set to each other and thus prevented us from implementing methods like isSubsetOf.
