Android Tap & Go... Almost as Easy as It Sounds

I had one teensy-weensy little problem with Android's Tap & Go feature for new phone set up. Although the NFC portion works fine, it is also VERY IMPORANT to enable Bluetooth PRIOR to running the sync. The sync code will temporarily turn on the bluetooth but it won't actuall work. Just enable bluetooth on the OLD phone prior to trying the Tap and Go and then it truly will be Tap and Go.

I had no luck googling for this issue or solution so noting it here for others to find. The phrase, "Sorry, Something Went Wrong" will appear on your new phone shortly have making the sync chime.

TIL From Users Today

I learn something about OpenStack each and every day and one of my broadest sources of OpenStack knowledge comes from my customers, the users of Time Warner Cable's OpenStack implementation.

Today, users' taught me, passively, by using it, about Shelving an instance. 

Suspending an instance puts it to sleep (via CPU suspension states) but the instance (virtual machines) is still using all of the memory and disk and cpu resources it was before (though the actual host CPU usage in this case is very very minimal.) Subtly different yet similar seems to be Pausing an instance. (I've never used this myself but am now checking to see if my users are using this.)

Stopping an instance still has the instance assigned to a hypervisor (essentially a compute host) and still "sort of" consumes resources on that host, most notably the ephemeral disk.

Shelving an instance makes a glance image snapshot of the instance and then removes all reference from the original hypervisor and compute host. It is consuming glance snapshot space in so doing but nothing on the hypervisor or compute host. So it is using the most minimal amount of resources possible.

Now to make this a real blog, I need to go add some links so that this is more shiny.
