32nd Week of 2021

Projects⚑

• New: Introduce pynbox the inbox management tool.

  Pynbox is a tool to improve the management of ideas, tasks, references, suggestions when I'm not in front of the computer. Right now I've got Markor for Android to register these quicknotes, but the reality is that I don't act upon them, so it's just a log of tasks that never get done, and ideas, references and suggestions that aren't registered in my knowledge or media management systems.

  On the computer there are also cases of tasks that are not worth registering in the task management system, or ideas that I get at a moment but don't have time to process at the moment.

  The idea then is to automatically sync the Android quicknote with syncthing, and have a special format for the file that allows pynbox to extract the elements from that file to the "inbox system". For example: +

  t. buy groceries
  tv. IT crowd
  i. Improve the inbox management
  
  I want a system to improve ...
  

  Gets introduced in the "inbox system" as a task, a TV suggestion and an idea.

• New: Introduce nyxt as a solution for a better browser.

  I've just stumbled upon nyxt (code), and it looks superb.
