Geo replication with syncthing

Some years ago I started using geo replication to keep a copy of all the pictures, docs, etc After being using BitTorrent sync and later resilio sync (even if I didn’t fully liked the idea of it being not open source), I gave up.

Lego Technic 42115 Lamborghini Sian FKP47

Xmas came with a good gift that I was able to finish mounting today, the Lego Lamborghini Sian FKP47 🛒#ad. The build experience was good, except for some issues related with not building in the best conditions of light, but more or less fixable… I forgot to add a gear that required me to bend a bit the model to put it back Realized that the gear shift wasn’t working because I didn’t put the piece in the right direction, so it was being blocked between two options Pick the wrong piece at one step so later on it was missing for another The biggest issue was that for the 2nd issue, I got into the motor drive had to be resettled and included some more dismantling, but nothing impossible. ...
