Install Graphite and StatsD on CentOS (updated for 6.4 x86_64)
# First do a fresh install of CentOS 5.7 i386, server configuration (no GUI)
# This should be performed as root since it's going to be installing a bunch of stuff
# --- Update things to make sure we have the latest patches ---
# Add EPEL so we can get reasonably recent packages

JVM + Invokedynamic versus CLR + DLR

Too much for teh twitterz :)

JVM + invokedynamic is in a completely different class than CLR + DLR, for the same reasons that JVM is in a different class than CLR to begin with.

CLR can only do its optimization up-front, before executing code. This is a large part of the reason why C# is designed the way it is: methods are non-virtual by default so they can be statically inlined, types can be specified as value-based so their allocation can be elided, and so on. But even with those language features CLR simply cannot optimize code to the level of a good, warmed-up JVM.

The JVM, on the other hand, optimizes and reoptimizes code while it runs. Regardless of whether methods are virtual/interface-dispatched, whether objects are transient, whether exception-handling is used heavily...the JVM sees through the surface and optimizes code appropriate for how it actually runs. This gives it optimization opportunities that CLR will never have without adding a comparable profiling JIT.

So how does this affect dynamic
