Upgrading Erlang vs upgrading the OS
Today, I have to use an Erlang application, that happens to need features that are only present in Erlang 16+. The VM I'm running this on was on Debian Wheezy, and backporting features or changing the Erlang libraries turned out to be a dead-end after about five minutes.
So what do I do? I upgrade to Jessie, of course, because it's much easier to upgrade Debian as a whole, and use its binary packages, than to compile Erlang on my own.
Thank you, Debian!
