Erlang

Overview of Erlang memory model, per thread heap and low thread footprint - http://www.javacodegeeks.com[..]/erlang-vs-java-memory-architecture.html

Concurrency is an area where Erlang shines - http://www.sics.se/~joe/apachevsyaws.html http://www.cincomsmalltalk.com[..]gView?showComments=true&entry=3364027251

And then, note the flatness of Erlang CPU-time curves and decent C (coroutine) performance compared to abysmal Java 6 and C++ (Pthreads) data in this benchmark - http://shootout.alioth.debian.org[..]ge&p1=hipe-2&p2=gpp-2&p3=gcc-2&p4=java-0

Another article about Erlang, contains pointers to useful site and reference large scale project - http://www.ddj.com[..]201001928?cid=RSSfeed_DDJ_ArchitectDebug http://www.infoq.com[..]2007/08/erlang-java-for-concurrent-futur http://www.ddj.com[..]og/archives/2007/10/functional_prog.html

How to have good C code -

- Be Disciplined About Namespace Management
- Clearly Document Published APIs
- Keep Data Types Abstract
- Use Polymorphism Judiciously
- Prefer Modularisation Over Conditional Compilation
- The Best Way to Modularise a Large C Codebase is Don't Have a Large C Codebase!
