Watching fresh slabs crack when we rush the curing step

On my last pour, some guys pushed to use a fast drying chemical instead of keeping it wet. They argue it lets customers drive on it sooner and we move to the next job. Others swear by soaking the concrete for days to avoid future problems. I saw a sidewalk we finished with the quick method start spiderwebbing in a month. But the slabs we watered down daily are holding up fine years later. It's annoying when speed seems to beat doing it right. How do you handle this on your sites?

Our promotion AI thinks my cat deserves a senior role

At my job, an AI tool reviews work data to suggest employees for promotions. It pulled info from a shared document where I had used my cat's name as a test entry. Now, I got an email saying 'Whiskers' is a top candidate for a management spot. It's a silly example of how bad data can lead to pretty odd ethical questions about these systems.

Red light trick for stargazing that changed my backyard astronomy game

Switching to a red flashlight saved my night vision and made spotting faint galaxies way easier, lol.
