Random ideas from Scala compiler hacker (@gkossakowski) on how we could improve specialization scheme by exploiting MethodHandles. What you read below is not a plan or a commitment of any kind. I just wanted to get it out from my head and hear what other people think while I'm busy with other things.

Specialization with method handles

Two canonical examples for specialization:

Function1
Tuple2

`Function1` specialization

Specializing Function1 is a lot easier because functions do not have specialized fields.

Miniboxing - Reverse Example

This is an example of using the miniboxing plugin in the Scala interpreter. For the benchmark, we reverse a 10M integer array, and compare the performance of the generic version and the miniboxed version.

You get 4-9x speedups by adding a single @miniboxed annotation:

scala> def reverse_gen[T](array: Array[T]): Unit = ...

Scaladays 2014 slides

As compiled by Kevin Wright a.k.a @thecoda

(executive producer of the movie, and I didn't even know it... clever huh?)

please, please, please - If you know of any slides/code/whatever not on here, then ping me on twitter or comment this Gist!

This gist will be updated as and when I find new information. So it's probably best not to fork it, or you'll miss the updates!

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
