That line about killing a coupon app at boot really hits home, because I had the same thing with some junk toolbar thing that came bundled with a PDF reader. It was set to check for updates every time I logged in and somehow ate 30 percent of my CPU, so disabling it in the startup tab cut my boot time from about 70 seconds to 15. Worth poking through that list every few months, since stuff sneaks back in with random updates.

Tossed my Super Lube in a drawer and never looked back. Factory lube on most switches is honestly fine for a daily driver. That mushy feel usually means way too much grease got packed into the slider. I did the same thing to a board of Oil Kings and it felt like typing through peanut butter. Now I only lube the springs if they ping and leave the rest alone.

Moss (that checker our school uses) nailed me sophomore year for the same thing, flagged like 40% match on a lab. What saved me was rewriting the logic in a totally different way, like swapping a for loop for a while loop and changing how I named stuff, so it wasn't just comments that were different. Comments help but the structure is what those tools really grab onto.
