State of The Networks - Feb 2021

A quick rundown on the state of the home-servers I run or applications I host on the cloud. Published while listening to: Malang With our temporary relocation, I currently manage two ‘home-labs’ - one which I remotely manage with a WireGuard tunnel and the other just a local-access only setup. The remote home-lab is essentially a Nextcloud server running on a DietPi OS spun on an RPi4. I pulled down the HAProxy config on the fronting server since that was no longer required. ...

DIY Passport Photos

Here’s a quick and simple way to make and print your own passport photos[PP]. I’ve used GIMP - which is a fabulous photo editing tool.

I’ve been sitting on the ledge for a while now and Whatsapp’s latest ultimatum is just what I needed to see myself out the doors. I value my freedom and privacy - way more than the perceived convenience and I’ve deleted my Whatsapp account for good.

Ephemeral devices

This is fascinating! A few GPS devices apparently had a mild(?) path offset issue few days ago: The issue has to do with the ephemeris data file, also called the EPO file (Extended Prediction Orbit) or Connected Predictive Ephemeris (CPE). Or simply the satellite pre-cache file. That’s the file that’s delivered to your device on a frequent basis (usually every few days). This file is what makes your watch near-instantly find GPS satellites when you go outside. It’s basically a cheat-sheet of where the satellites are for the next few days, or up to a week or so. ...
