  • I had a similar conversation with my wife a few weeks ago. We were watching the hydraulic press channel, where they were compressing water to very high pressures. When the water inevitably squirted out of the chamber, it turned to steam. My wife said yeah that makes sense, applying that much energy to compress the water would increase its temperature, so it wants to expand to become steam. Then I thought about it a while, and said wait, according to first principles of thermodynamics, shouldn’t compressing water lower it’s temperature?! The turns out the real world is correct, I was wrong.














  • This is nothing new. I worked at a small computer shop in a small town between 2005-2007. The owner treated memory as a commodity. He checked national ram module prices daily. Buying low, and selling high. He sometimes adjusted the module price on a per-customer basis.

    I get that it’s much harder to do that with online stores, where prices are published to multiple places, and for chain stores where the price needs to be consistent between locations.
