I got severely dinged for saying in a standup that I had forgotten what I was doing the previous day.
So I bought an A4 hardback notebook, and started logging everything I did. I wish I had been doing that since I started in this business; it's a really good work habit.
I keep a lot of journals. Bullet journals for my daily tasks/planning. Long form journals for deep subject matter: maths, graphics, algorithms, etc. Combined with my writing it's definitely been a useful way to see how I've evolved my thinking over time, etc.
Isn't this what Jira, Azure Boards, sticky notes are for? You reference the sticky note when talking about what you did. If there's no note for it then your planning was probably bad.
I tried paper and log books for a long time (I've got half a filing cabinets worth), but no matter what system I used I couldn't always find what I wanted. (When did I last modify routine xyz, and why?).
Moving to flat ascii files meant it's searchable and has longevity as it doesn't need any specific tool or app. I can also carry the lot around with me - very useful on site.
Well, I never used my log books as an information retrieval system; the prime purpose was to help me remember what I did an hour ago, a day ago, a week ago.
Of course, I have a digital file of timestamped and commented code snippets and pieces of config. But that's just about the activity of coding; I now think a handwritten log is a good idea for anyone, whatever their trade.
The reason I recommend a hardback notebook, is because it offers the best CYA protection (I was caned as a child). It's sorta symbolic - hard evidence, if you like.
[Edit] You can also scribble in your notebook in meetings, while glancing furtively over your spectacle rims, to intimidate the speaker. Hard copy is power.
I use a heirarchy of folders and within them I create a text file for each main task:
\work\customername\StockSystem
MyCust001 - Interface not updating PickStatus.txt
MyCust002 - Add Stock Check Flag to ScanPullStock.txt
MyCust003 - Look at enhancing Batch Split screen.txt
I use the numbers as a quick reference within all my documents.
\personal\Diving
Diving book recommendations.txt
Diving gas tables.txt
\personal\DIY
Standard screw sizes.txt
Choosing new security lights.txt
Getting new consumer unit fitted.txt
I add the date and time to a line whenever I start, or after a break. (Pressing F7 on UltraEdit does this automatically). I can use this retrospectively to see how long things took.
