SmartOS albeit powerful, makes some easy things like figuring out a "version" of SmartOS very difficult and confusing. To someone like Basho who makes packages for SmartOS, it is enough to drive us (me) insane trying to figure out how to label the packages.

The problem lies in trying to define the version at all. Is the version you care about listed in uname -a? How about a file in /etc/ that tells you? The answer to bolth of those questions is "no". uname -v gives you a string like joyent_20130125T031721Z The only file in /etc/ that comes close is pkgsrc_version, but that is only sometimes available on the system. The real answer is a combination of the Global Zone snapshot version and the pkgsrc version in the guest zones.


So how do I label my packages for SmartOS?

With the uname -v example above, joyent_20130125T031721Z describes the global zone, and has some influence on how apps run, but not enough to determine which package will work on which system. Plus I d

Erlang and Named Pipes

The intention of this post is to provide a solution (with examples) to a somewhat uncommon issue in Erlang. I hate searching for answers to the same problems over and over, and I had a hard time finding answers to this particular problem, so I wrote it all down once I figured it out. If one day you decide to read and write data through fifo's (named pipes) and then decide you want to read or write the other end of the pipe from Erlang, this post is for you.

The Problem

I wanted to read and write to a fifo from a C/C++ app and have an Erlang app communicate over the other end of that fifo. Put simply, Erlang doesn't really support what I was trying to do. You cannot just file:open/2 a fifo, or any special device for that matter, in Erlang and expect it to work. This is documented in Erlang's FAQ.

The Solution! ... ???
