Ask HN: How do you take technical notes?

I've been a Bear.app user for some time now, recently I factory reset my laptop and was looking for maybe an alternative just to spice things up, an app or maybe a setup, to take notes related to my job.

Things I'd like to have:

- Good looking notes - Supports markdown - Allows for easy filtering

I'm always interested in knowing how other people do stuff so I can learn and take notes (no pun intended).
