So I use Sinatra which uses the securerandom gem. Been using it under
vmware/ubuntu 12 for a while and went to run my app on Digitalocean, and
sinatra wouldn’t start.
doing a require sinatra would hang irb had to CTRL-Z to get out.
Tracked it down to the call to SecureRandom.hex().
I’m guessing this is some bad interaction when running under KVM
That’s what digitalocean uses. Been running the same app with same
gems under vmware and it works fine. Only other difference is that I
ubuntu 12 at home and on digitalocean I used 14.
