Learning Journal 001 - A New Series

This is a simple series that's primarily going to be focused on incentivising learning and documenting what I do outside of my main aims for this year (LPTHW and Odin Project with a touch of CS thrown in).

Essentially, I'm keeping a Learning Journal, hence the category name these posts will reside within.


I'm writing this mostly to remind myself:

  • Short description or sentence on thing
  • Link if applicable
  • Short note on why it was useful if applicable
  • Further blog post if suitable
  • Photos where applicable

Learning points will be raised as separate headed sections within one daily coverage post.

One interesting tip was the addition of a 'tail light' on the back of a chair. Described fully in this video:

Saw this through a HackerNews post which lead to a bit of extra learning about how Let Encrypt and specifically Certbot handles authentication:


I suspect a lot of these extra-curricular learning point might come from HackerNews!
