I saw a coffee shop owner on YouTube break down how water hardness totally changes extraction. He did a side by side test with filtered and tap, the difference in taste was wild. My tap water is super hard so my coffee used to taste off no matter the beans. Using a basic Brita filter made it way smoother, not fancy at all. It's not about being extra, some water just has minerals that fight with the coffee oils.

Lost a whole project to a cafe's bad wifi in Lisbon last year... that pain is too real. Jake_carter is right, it's a rough lesson to learn. The quiet and the reliability in a coworking spot just makes that monthly fee feel small.

Bad luck? Come on, that's just asking for it. A worn chain puts extra stress on the whole drivetrain, and it's gonna fail when you put power down. I carry a quick link and a small multi-tool with a chain breaker, because walking out is the worst. Isn't it better to spend five minutes fixing it than an hour pushing your bike?
