Auditing ports and packages with 'pkg ng'
We used to use jailaudit to produce a portaudit for all our jails, but it would seem that `portaudit` and `jailaudit` need some work before they are happy in the newer ecosystem. However new _pkg ng_ tools can audit things directly including jails. This is great, but we were lacking an easy way to audit all our jails as we used to.
Logging with Ruby Sinatra and Passenger
If you read around about logging in the wonderful Sinatra framework you'll tend to find something that suggests you just reopen STDOUT and STDERR in your `config.ru` file. That worked fine and has served me well for quite a while. All that changed with more recent versions of the Passenger Gem which I tend to use in concert with Nginx to deploy my Ruby web applications. You see Passenger now seems to use STDOUT to do a lot of chatting to itself on and re-directing it in the above fashion just breaks things. Here is the way I work around that.
