Found a stash of old selenium cells in a junk shop last week

Nah, gotta push back on that. Those old Weston and Gossen cells definitely had rated sensitivity specs printed right on the factory data sheets. I've got a stack of old instrument catalogs from the 50s and 60s, and they list things like "sensitivity at 5400k color temp" with pretty tight tolerances. The 10% thing might sound loose compared to modern cells, but for something that's been sitting for 60 years that's actually pretty impressive. My theory is that the sealed packaging kept them from getting contaminated by humidity and crap in the air. I've seen the exact same model of cells that were stored open drop off by 30-40% in just a few decades. So yeah, it's a fluke that those specific ones were stored right, but the technology itself was solid.

Shoutout to a random vendor at a networking meetup

Honestly I think that story sounds a little too perfect. Most vendors at networking events are trying to sell you something, not give you a free therapy session.

My dad told me to always round up on car maintenance and I thought he was just being paranoid

Guess I'll find out the hard way when my engine explodes.

I finally figured out why my air fryer chicken wings were always soggy

Feel your pain on the drying thing, that's a real game changer. I did the same thing with my old toaster oven, kept getting sad, limp fries until I realized I was tossing them in oil while they were still wet. Took me way too long to figure out, feel a bit dumb about it now.

Debate: should you leave your fire pit ashes in or clean them out every time?

Leaving a thin layer can actually protect the fire pit from rust and help start your next fire faster.
