Learnings

General

• default options are strong: I always ask myself, why people don't use my cool, sophisticated software, but Windows 10 / Edge / Chrome / Google Search / whatever

Project Management

• we mostly use the tools we know, e.g. we default to Trello, Excel, Google Docs etc.
• these tools shape how we think, e.g. "everything is a tablesheet, kanban etc."
• most use of this software is fragile, because it is owned by for-profit companies and closed source -> moral dilemma: buyer's need is not seller's need
• idea: use gitea/gitlab/github issues
• pros: everything in one place, no sending of files (excel etc), no additional accounts (only on the git platform), connection between management and code, removes complexity through using markdown
• cons: everyone needs an account, everyone has to learn simple markdown
• use labels for categorical information (e.g. bug, feature), use milestones for time-bound chunks of work; do not use milestones for categorical information

Commandline

• signals: sigint, sigterm, sigkill
• terminal multiplexer:
  • session (e.g. "work" or "personal") ->
  • window (e.g. "work/rust" or "work/nodejs") ->
  • panel (e.g. "work/rust/main.rs" or "work/rust/lib.rs")
• why multiplexer instead of multiple window manager windows: not always access to window manager (e.g. on server), also increases complexity (more software)

Concepts: multiple notes or single summary?

• in the daily note: Sure, because I learned it today. But I learn everything on a specific day, so I would not be able to add anything to a summary.
• in the summary: There are topics I'm heavily invested, e.g. Rust, Linux, nutrition, thinking, philosophy etc. There are also topics a "cheatsheet" is great, e.g. Vim. But I would always keep track which topics already have a summary, if/when I can start a new summary etc.

Implementation: blog or wiki?

• clean, simple design
• internal linking
• free to use, free to share (https://en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_Attribution-ShareAlike_3.0_Unported_License)
• access to the data's history

Ideas

• this is just my mental model, build your own
• life can be thought about in different environments, let's call them sessions; example: work environment, private environment, gym environment
• an environment can be divided into different projects, let's call them windows; example: work/client A, work/client B, private/hobby A
• a project can be divided into different tasks, let's call them panes; example: work/client A/add feature A, work/client B/add feature Z, private/hobby A/do workout D
• so I have different sessions, e.g. working on a tool, writing my blog
• when I want to work on my tool, I hit mod + s to show my sessions and then change to my "work on my tool" session, with all the tools set up
• when I want to switch to writing my blog, I hit mod + s again and go to my "write my blog" session, with all the tools set up

Shortcuts

• mod stands for modifier key; the default modifier key is ctrl + b, I changed mine to ctrl + a for ergonomics
• example: when I write mod + x, then hit your modifier key (defaults to ctrl + b) and x
• all shortcuts: mod + ?
• show all sessions: mod + s
• new window: mod + c
• kill window: mod + x
• go to next pane: mod + n
• go to previous pane: mod + p
• scroll up/down: mod, pageup/pagedown, quit: q
