Power up on Power Restore

Power up on Power On is fairly important for people running servers … but its a little tricky if you are recycling Mac Minis for hosting VM hosts (eg Proxmox)

Fortunately some others have done good work and worked out the magic commands you need.

Postgres and Moving Databases

Recently I had to recover a Postgres DB and for 'convenience' I moved it from its original Linux environment to OS X. The process had a few wrinkles most important was that the linux environment used a locale of en_US.utf8 and MAC OS only has en_US.UTF-8

Ubiquiti Unifi Site Magic

Site Magic



I was going to write a long article about the Site Magic feature on the Unifi Gateway devices. But I can't. And the reason is particularly rare and satisfying. If you are using this product for what it is designed and marketed to do.

It is easy to set up

It just works.


So if you want to

Allow full connection between two or more non-overlapping networks located behind Ubiquiti Unifi gateways


and provided

At least one those gateways having a public IP address

The gateways have a communication path between them

Don't need to deal with more than 5 gateways (apparently this limit will change)


A half dozen mouse clicks will get the job done. So far it seems to manage IP address changes and restore itself after network loss with no intervention and has replaced a rather complex IPSec VPN setup.

This type of issue is likely to pop up again as other components move repositories.

Apparently this is all fixed in a later version of microk8s than I am currently running … but that is a story for another day

How to keep an iPad awake

The database on my one of my health tracking apps was corrupted and the FAQ said to remove the app and reinstall it. I have been using this app for a long time and the iPad Pro its running on is due for replacement. Apparently I have a lot of data in it and security features I can't turn off (auto lock screen) mean that it needs to be kept awake while it won loads.

So how do you keep an iPad awake for more than 24 hours …
