when i realise that you can save one keypress on a microwave by typing in 90 instead of 130 for one and a half minutes
when i remember that my microwave is one of the ones with a knob instead of a keypad so this cool trick doesn't work for me
in unrelated news i just found out that ffmpeg lets you reverse videos by just applying a video filter called "reverse" so that's cool
people seem to have trouble believing that microwaves with keypads exist so here's an example of one 
and here's an explanation of how it works:
digits fill from the right to the left, so typing in "5" always means five seconds and never five minutes. five minutes is "500".
one minute and thirty seconds is "130", which is interpreted as "1:30". however, typing "60" does not autocorrect to "1:00", it stays as sixty seconds. you can go as high as ninety-nine seconds. thus, you can type in "90" and it'll run for one minute thirty seconds
okay now there are other people who are having trouble believing microwaves *without* keypads exist 
here's one with a knob
explaining the revolutionary concept of microwave to standard time conversion
@lynnesbian ours has ONLY knobs! digital technology is for suckers
@theoutrider @lynnesbian hell yeah, knob squad!
(i really hope that's not a euphemism for anything lewd)
@grainloom @lynnesbian an acquaintance of mine once proudly reported that while working on a heavily skeuomorphic application he had just written code for an event called knobStroke()
@lynnesbian this needs Suricrasia Online-like narration
@lynnesbian when will we have slider microwave
@lynnesbian personally I want a portrait qwerty microwave
@lynnesbian it literally looks like they tried to take an analog knob microwave (which makes mechanical sense) and lift-and-shift to the digital space
I'm looking forward to cloud-based knob microwaves
@lynnesbian yeah but i'm so oldschool I have a *mechanical knob* without digital shit so I have even less accuracy than you but I can feel like I do
@lynnesbian I have one with a knob and no numbers. It’s the worst microwave. I mean yeah it heats but it goes in 0:10 increments until you hit 5:00 and then increments in 0:30. Except when it’s ignoring the knob (and increments not at all).
Which is bad but not as bad as when you try to stop it beeping. One you miss the 0:01 mark, it WILL BEEP LOUDLY THREE TIMES no matter what. And then again once every minute until you open the door.
look you fools this is PROOF of knob microwaves i personally own one
