    ACs are just heat pumps where they forgot to install the reversing valve.

    Heat pumps running in heating mode are basically ACs that are trying to cool down the outside. The fundamental technology just moves heat from one place to another, leaving one place warmer and one place colder.

    This is also how fridges and freezers work - they have heat pumps that pump out the heat from inside their box and as such make the room they are in warmer.


  • It’s not out of the question to have ‘memory leaks’ - apps accumulating more memory by keeping around references to more and more objects - but memory leaks in the stricter sense of not deallocating objects that you no longer have references to is less likely. Regardless, the OOM killer will come for your app, no matter how good you’ve been about managing your memory, as long as someone else wants to have the memory and you’re the one who has been active the least recently.










  • I was previously convinced that taking cold showers was my only saving grace during hot summers, but this year I got the advice to try to take a warm shower a short while before bed, and I’m surprised to say that it has helped. This is for high 20s though so YMMV for sure.

    Other things that help:

    • Open windows when outdoor temperature is lower than indoor temperature, and try to get a cross breeze going if possible
    • Keep light out of the house by closing blinds during the day
    • Wear linen clothing and use linen bedding, this material works better for warm conditions
    • Fans help reduce perceived temperature by several degrees
