My thoughts on MessagePack

Hi. My name is Sadayuki "Sada" Furuhashi. I am the author of the MessagePack serialization format as well as its implementation in C/C++/Ruby.

Recently, MessagePack made it to the front page of Hacker News with this blog entry by Olaf, the creator of the Facebook game ZeroPilot. In the comment thread, there were several criticisms for the blog post as well as MessagePack itself, and I thought this was a good opportunity for me to address the questions and share my thoughts.

My high-level response to the comments

To the best of my understanding, roughly speaking, the criticisms fell into the following two categories.

	# Makefile for a go project

	# Author: Jon Eisen
	# site: joneisen.me
	#
	# Targets:
	# all: Builds the code
	# build: Builds the code
	# fmt: Formats the source files
	# clean: cleans the code

	package main

	"bytes"

	"crypto/rand"
	"crypto/rsa"

	"fmt"
	)

	// this is a very basic mutex implementation
	// its aim is to try to acquire access to a critical section or fail.
	// there is no spinlock or event-waiting going on.
	// in case it fails to acquire the lock, it simply returns false.
