NOTE, THIS DOESN’T WORK FOR ME :( I was not able to get this to work. Something about compiling the required apps mentioned in the instructions below. Adding the patches worked fine. I compiled source verified install worked on phone. Then I compiled source with patches added, and verified it worked on the phone. As soon as I compiled in the SolidHal apps (PRODUCT_PACKAGES += GmsCore GsfProxy FakeStore FDroid FDroidPrivilegedExtension auroraservices) per the instructions below....

How to backup your Ubiquiti NVR/CloudKey+ Protect videos remotely to Backblaze B2

Sadly, Ubiquiti offers no way to backup the videos stored on their NVR and Cloudkey appliances. This sucks if you have a fire, or breakin, and the device is stolen or otherwise compromised. Checking various reddit and ubiquiti community posts, it doesn’t look like a proper solution is coming either (been asked for for years!) So, I decided to try and fix this issue myself. Note this takes a LONG TIME to backup if you have continuous recording, or, lots of alerts, so it might not work for you – for example on Starlink, it takes approximately 4 hours for me to backup a single day of alerts from only 6 cameras....

I also leave the national weather service images since they take up very little space....

Setting up a Matrix server for Secure Encrypted Communications through almost all the channels you and your friends use.

With all the privacy issues these days I decided to check out alternatives to using standard services. With that I found Matrix which allows for a secure ‘slack like’ service that also has ‘bridges’ that let you connect to iMessage, Slack, Signal, Facebook even Twitter and Instagram. I have not fully configured this, this is mainly for my records purposes and I stole most of this from the excellent article I found called Running your own secure communication service with Matrix and Jitsi....

Setting up SDRPlay RSPDX on Armbian running on an ODroid N2+ for network radio tuning.

Today I received my SDRPlay RSPDx device and decided to get it running on my remote radio server. I’m still not sure if I’ll run this remote or locally, but, wanted to have the option for whatever I do decide to do. The setup is pretty painless and involves a few commands. I’m going to assume you already have your Armbian server setup and can SSH to it and have a special user called ‘radio’ setup to run all of this as....
