  • I feel like many programmers (or their management) have grown ignorant to resource limitations over the past decade or so.

    Obviously there is good examples like many linux distros running well on 4GB RAM and the like, but when it comes to windows, websites and proprietary programs, they gobble up insane amounts of RAM to provide almost the same functionality as in 2010.





  • I know it is a bit of a silly answer but here we go:

    My brother had installed a game-boy emulator on the family PC when my parents had prohibited gameboys from the house. My older siblings bought some though and hid them, but i was too young for that. (They also didn’t tell me).

    Anyways, so at the time Pokémon Ruby and Sapphire was the hot shit. I played Ruby on the emulator and i loved it. There was just one problem. The “nebula” animation that is transparent in the gameboy version was solid in the emulator. When i entered a cave i had to find a way to pass it blindly. This was before we had proper internet access at home, so i couldn’t look up the cave layout.

    I had to gave up after the second gym or so. When i got older and my grandma bought me a gameboy, i played Ruby like crazy as i finally could progress.








  • Oh boy. So the heat pump is probably one of the most important inventions without which modern society wouldnt exist. It uses a refrigerant that has a low boiling point. It is liquified through the pressure of a pump on one side, and let to evaporate on the other side.

    Because of the evaporation it can draw heat from there and then give it off at the other side. This way it can cool the cold side more and warm up the warm side more, subsequently “pumping” the heat from one to the other side.

    Your fridge uses a heat pump. Most AC units use heat pumps. Any industrial room cooling like warehouses, trucks etc. involves heat pumps.

    Now comes the neat thing. For heating a heat pump can have an efficiency factor up to around 4. So 1kW of electrical power can give you up to 4kW of heating power. This is because the electricity isn’t transformed to thermic energy, but rather used to move thermic energy from the outside inside.

    Heat pumps are amazing, especially as modern ones provide both AC and heating efficiently. Only caveat is that the efficiency is dependent on the temperature difference it needs to surpass. Because of that older radiator installations that were designed for a higher temperature might need replacement with newer larger radiators. Also if it gets really really cold you might need a classical heater to support the system.
