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.

Auto-starting VirtualBox VMs on OS X

After finding a lot of other posts on the topic that didn't work out for me this one did the trick so I'm reposting for my own sense of self preservation.

Link to original article.

Copy the Virtualbox autostart plist template file to your system's LaunchDaemons folder.

sudo cp \

/Applications/VirtualBox.app/Contents/MacOS/org.virtualbox.vboxautostart.plist \

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
