Fun that this is brought up at this time. Just a few days ago I tried to program the programable thermostat of my grandma. I am convinced that the thing has a bug making it impossible to select a schedule… It has a lot of buttons and a screen, but due to a minuscule mistake in the interface it’s no better than a temperature slider…

Does a microkernel matter for anyone but nerds? Maybe companies that make variants of the OS?

Honnestly those razor-blades are a scam and I spend a lot less money since I switched to safety razors. A bit more technical to use but totally worth it I think
