I recently went on quite a rabbit hole regarding the .well-known directory, and wrote about it.

Hey Thanks for reading, and I'm glad you found it interesting.

To my understanding, Webfinger provides a standard API for discovering the user profile details no matter the software running on the node.

For example,

$ curl https://programming.dev/.well-known/webfinger\?resource\=acct:snowe@programming.dev | jq
{
  "subject": "acct:snowe@programming.dev",
  "links": [
    {
      "rel": "http://webfinger.net/rel/profile-page",
      "type": "text/html",
      "href": "https://programming.dev/u/snowe"
    },
    {
      "rel": "self",
      "type": "application/activity+json",
      "href": "https://programming.dev/u/snowe",
      "properties": {
        "https://www.w3.org/ns/activitystreams#type": "Person"
      }
    }
  ]
}

It's a really nice anecdote where I see myself reflected haha, I'm just in the middle of something similar with RSA and Ed25519, and also the post-quantum cryptography scene.
But usually once I'm done investigating and I think I understood something well enough I simply bookmark the links, write some bullet points in my notes and that's it.

Do you also have this issue? Do you finish the investigation and start writing for a blog post right away? Or do you just come back to it after some time?

[-] ishanpage@programming.dev 5 points 1 year ago

Haha this is exactly me. That habit of losing the knowledge rapidly post investigation is something I'm trying to break, and that's part of the reason I banged out this blog post immediately after my itch was satisfied.

The "I have to tell people about this NOW" vibe also carried me through completing my website (just so I could publish this blog post)

[-] silver@lemmy.brendan.ie 2 points 1 year ago

Out of curiosity are ye planning to do a post about RSA and ED25519?

[-] pe1uca@lemmy.pe1uca.dev 3 points 1 year ago

I do want to, not sure when, but I'll find the time since OP gave me a bit of a boost in confidence I can do it :)

[-] ishanpage@programming.dev 3 points 1 year ago

I'll be sure to read it when you do :)
