Buying household groceries or anything of size sounds annoying or impossible on bike.

Not sure why buying groceries on a bike would be annoying or impossible. I do all my grocery shopping by bike, every single day, sometimes twice a day. Just bring a backpack.

As for ‘anything of size’, what would you need to transport? I still have a car, but I use it so little that I only need to buy gas maybe once or twice a year.

bluetooth draining my phone faster

Bluetooth was specifically designed to be very low power. With a bluetooth headphone there is a battery in the headphone to power the amplifier and provide the energy to move the speaker diaphragm. With passive (wired) headphones, this has to be powered by your phone.

Do you really think that a phone that has to directly drive the speakers in a headphone uses less power than a phone that only has to power the bluetooth transmitter?

I love wired headphones, but I wouldn’t ever drive them directly from my phone. Especially higher end headphones are more difficult to drive anyway, so I use a (wired) external DAC/amp with it’s own internal battery for using my wired headphones.

You can do all file management operations from the command line. No need to use the Finder.

Do you even git?

Surely experiment 1…n should be branches.
