@ObtuseRecluse Muc-Off chain cleaner

@taigaland Sure, but it doesn't reach in between the links of the chain..

@behweh @tinx It's basically just how i looked once i saw all that dirt on the drive train

It's that time of the year again where road salt it trying to eat your bike. Luckily i got this 3D printed chain cleaner as a birthday present (thx @tinx ). I tried it for the first time today and it worked okay. I think stiffer toothbrush heads might improve the cleaning (i used medium ones).

This is the 3D model https://www.printables.com/model/123026-bike-chain-cleaner-toothbrush-version

Better watch out next time you use WiFi on a plane. Because it's broadcasted unencrypted across the area of an entire continent via a satellite link. And it can be received using of the shelf TV satellite dishes.

Good part is: private connections are mostly encrypted due to stuff like Let's Encrypt.

Bad part: critical infrastructure doesn't use Let's Encrypt.
