Richard P Feynman – FUN TO IMAGINE (full)

Posted by jpluimers on 2020/01/24

On my watch list: Richard P Feynman – FUN TO IMAGINE (full) – YouTube

The first 5 minutes are already so great and full of imagination, that I need to find time to watch it once more after already watching it 2 times in full with some time in-between to reflect.

Viewing certbot installed certificates and their expiry dates

Posted by jpluimers on 2020/01/24

A simple tip on the certbot command-line from [WayBack] User Guide — Certbot 0.19.0.dev0 documentation – Managing certificates (Automatically enable HTTPS on your website with EFF’s Certbot, deploying Let’s Encrypt certificates.):

To view a list of the certificates Certbot knows about, run the certificates subcommand:

certbot certificates

This returns information in the following format:

Found the following certs:
  Certificate Name: example.com
    Domains: example.com, www.example.com
    Expiry Date: 2017-02-19 19:53:00+00:00 (VALID: 30 days)
    Certificate Path: /etc/letsencrypt/live/example.com/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/example.com/privkey.pem
