Technically why is processes in Erlang more efficient than OS threads?
- by Jonas
Spawning processes seam to be much more efficient in Erlang than starting new threads using the OS (i.e. by using Java or C). Erlang spawns thousands and millions of processes in a short period of time. I know that they are different since Erlang do per process GC and processes in Erlang are implemented the same way on all platforms which…Read the article

Using trace and dbg in Erlang

I am trying to start using erlang:trace/3 and the dbg module to trace the behaviour of a live production system without taking the server down.

Erlang: Interfacing with Xalan: port driver or nif?
- by mwt
I'd like to get a real XSLT processor working with erlang. Which would be the best interface, nif or port driver?

Also, I'd like to allow erlang callbacks during the transformation. Does that…Read the article
