A New Garbage Collector and Memory Profiler for iOS/MonoTouch
MonoTouch for iOS now supports the generational garbage collector SGen. Until recently this was an experimental option only available on the full version of Mono. Along with it comes a Memory Profiler for iOS that it accessible via the MonoDevelop IDE.
Bitmap Marking GC for Ruby Improves Memory Usage
The successor of Ruby 1.9.3 will replace the current Lazy Sweep Garbage Collector with a Bitmap Marking GC, which will significantly reduce Ruby's memory usage for parallel programs, similar to Ruby Enterprise Edition's copy-on-write-friendly GC. We talked with Narihiro Nakamura who implemented both the current Lazy Sweep and the Bitmap Marking GC.

The Azul Garbage Collector
Azul's recently announced Zing product brings their Garbage Collector, which achieves both pauseless garbage collection and a high tolerance to the factors which typically impact collection and application responsiveness, to Java programs running on Intel and AMD based servers. This article takes a detailed look at how Azul has been able to achieve these design goals.

Understanding Java Garbage Collection and What You Can Do about It
Gil Tene explains the workings of a garbage collector: terminology, metrics, fundamentals, key mechanisms, classification of current GCs, the “Application Memory Wall” problem, and details Azul C4 GC.
Do You Really Get Memory?
Jevgeni Kabanov creates a CPU model in Java in an attempt to explain the underlying mechanism of memory performance bottlenecks and the need for a correlated hardware, OS and JVM improvement.

Attila Szegedi on JVM and GC Performance Tuning at Twitter
Attila Szegedi talks about performance tuning Java and Scala programs at Twitter: how to approach GC problems, the importance of asynchronous I/O, when to use MySQL/Cassandra/Redis, and much more.
Gil Tene Discusses Garbage Collection, the OpenJDK and the JCP
Gil Tene talks to Charles Humble about different garbage collection techniques, and specific collectors including Azul's C4, IBM's Balanced GC, and Oracle's Garbage First, before moving on to discuss both the JCP and OpenJDK.
Ari Zilka on RAM is the New Disk & BigMemory
Terracotta creator Ari Zilka talks about about the RAM is the new disk and argues for scaling up before scaling out, comparing the architectural approaches of lots of VMs with small heaps vs. a few JVMs with very large heaps. Ari introduces BigMemory, a Java add-on to Enterprise Ehcache, which allows app designs with huge amounts of memory accessible in-process, with minimal garbage collection.
