Gut feelings have their place though. AI heatmaps tell you where people look, not why they clicked. That 40% lift could be from the change itself, not the tool.

Same thing happened to me with a "masterclass" on web development. The guy spent like 20 minutes talking about his desk setup before he even opened a code editor. Ended up refunding it through Udemy's policy and watched a free series on YouTube from some kid who explained everything way better. Sometimes those paid courses are just padding their hours to look legit.

Hot glue is cheaper than a new board, just saying.

Ngl evannelson I heard somewhere that misprints are actually way rarer than book club editions so it sucks either way.

Yeah @sethanderson you're mostly right but I gotta push back a little. The ground rod is super important for safety and for keeping noise out of the system, no argument there. But if your ground path has a loop or you've got different ground potentials between your equipment, you can actually make hum worse instead of better. Had a buddy who drove a rod, tied everything to it, and ended up with a 60hz buzz that drove him nuts until he lifted the shield on one end of the signal cable. The old phone guy knew his stuff for sure, just gotta make sure you're not grounding stuff in two different places that have different voltage potentials. A single point ground is usually the way to go if you can manage it.
