Abstract: Garbage Collection is a way of automatically reclaiming and reusing program memory that is no longer needed. It was invented in 1959 by John McCarthy as part of the implementation of the programming language LISP. A language with garbage collection means the programmer never has to worry about free’ing memory and frees their intellect to work on more interesting problems.

Once the province of languages that were regarded as esoteric and slow, garbage collection is now in every dominant language in use today (Java, R, Python, Ruby, Go, Lua, Lisp).

I give an overview of garbage collection algorithms and discuss some of the trade-offs that affect space/time performance, ease of implementation, and portability. We’ll have a brief splash around inside the implementation of the programming language Lua (PUC-Rio, Brazil).

Bio: David is a Research Software Engineer in the University of Sheffield’s RSE group.
