Does any of you write notes about what you learn in your day to day job? I recently covered a colleague that went on vacation because the product was going to be shipped during his vacay and I was assigned to do some tweaks, since I am the only one on that team that also knows frontend apart from him. My job is computer vision and he is a frontend dev, so when I sat to take a look, I started to learn new tricks for frontend and I felt the need to write them down because when I go back to my routine, I will forget them since I won’t use them for computer vision. However, knowing frontend is always handy.. do you guys take notes on stuff you might not touch again but it’s useful to keep somewhere?

All the time.

I don't actually. The useful stuff just kinda sticks in the back on my brain when it's really useful and hard to google. Otherwise I just let it go and google it again when the time comes.

Yes, I maintain what I call as "Today I learned" or "Grindset" note. Everyday for 15 mins I just sit down and write down what I learnt. It can be bug or code snippet or resolution of bug or idea.

I have been doing it for 5 years and it has helped me write blogs for many years. It also serves as my backup notes.

It depends on what kind of learner you are.

If you can memorize better when writing stuff down, take notes.

Other examples are recording voice notes...

IMHO it helps a lot to have *some* sort of documentation. Might sound stupid, but our job is taxing. It's nice to have a starting point the next day. It's even nicer having a look at what you achieved when the week is seemingly a "I'm too stupid for everything" kind of week and you can look at / hear what you achieved. Small victory laps are always a nice backup.

Plus... when you do a lot of juggling tasks like me, you need the safety net.

Our brain was absolutely not made for concurrency / multi tasking, so it eases dramatically the pain of context switching.
