#weeklyreview 46/23

After the successful mushroom foraging session on Saturday it was now my duty to risk my life and eat them.

If you’re reading this … I survived 😉 Turned into one delicious meal 😉

Was playing around with ownTracks as a self-hosted location tracking app. The idea is to have the ability to track various mobile devices but keep the data under my control. While the built-in iOS (“Find my”) and Android (Google Maps) are convenient, the also leave the data on Apples/Google server to fuck around with.

ownTracks is a simple app that can send the position data to an arbitrary MQTT backend. I’m hosting my own Mosquitto instance and use the ownTracks Recorder app to visualise the data on OpenStreetMaps.

The connection to the MQTT broker is of course using TLS encryption. To add security and hide the data from the MQTT broker one can define an encryption passphrase. Now the MQTT broker sees only encrypted data. Via this secret you can also share your position with friends. All devices with the same encryption key can see the location of the other members.

It gets interesting when you add POIs and geofences. The clients can send a special message when leaving or entering a certain location. This way one can automate geo location based events (e.q. the classical “turn the lights on when I’m coming home” example etc.). The ownTracks Recorder app also records “tracks” means it doesn’t only collect the individual points but draws line/routes where one moved. So you can display your own moving profile over time.

Wednesday

I felt fancy and took my coffee gear to the office. Thats the Wacaco Picopresso and the HARIO Travel Grinder. I pre-weighed the coffee beans at home and stored them in the little metal containers I’ve kept from my coffee bean advent calendar last year.

Saturday – mushrooms again

On Saturday we’ve been invited over to our friends place in the next village for a little walk in the forest and maybe some mushroom picking again.

And it was crazy. On just a 30m strip right outside the village we filled 3 baskets of mushrooms and had to stop as our storage capacity was exceeded. Those will be cut into small pieces and dried up for later use. Mostly in sauces to stews and the like.
