On the 1920s library renovation in Chicago, we used a modern polymer-modified plaster that adhered perfectly to the old lath. That stuff cured in half the time of traditional lime plaster and didn't require constant misting. Lime plaster might be authentic, but it's incredibly fussy and prone to cracking if the building settles even a little. Modern mixes have additives that allow for flexibility and moisture management, which is crucial in older structures with damp issues. I've seen lime fail in less than a decade on retrofitted walls where modern plaster holds up. The nostalgia for old materials often overlooks how far formulation science has come.

My last PC was a total oven, hitting 90C on the GPU during gaming sessions. I read about positive pressure on some subreddit (the buildapc one, I think) and swapped my fan configuration. Dropped my peak temps by a good 12 degrees, and the dust buildup slowed way down too. It's wild how such a simple fix can make such a huge difference.
