# Random Rumblings

### by Joshua Branson — April 13, 2018

Please note that this blog posts refers to a time when this site used Wordpress. It is now using Haunt.

So today I had a full day of just doing whatever I wanted. Here's a recap of the cool things that I was able to do:

- I got one of my websites to use let's encrypt: www.gnusites.com. As an interesting sidenote, https://www.gnucode.me now points t www.gnusites.com. That's not intentional. I'll have to fix that another day.
- I fixed a really annoying error with gnus, which is an email client for emacs. Basically it was trying to access a server that didn't exist. (nntp "news"). Every time I started gnus, it would try to access this fake server and fail. A simple (setq gnus-select-method '(nnnil "")) solved the problem.
- I made this site serve images from a CDN (allegedly). I'll have to verify that it actually is.
- get org babel sh code working on remote machines! This actually works! I wish I was writing this post in org-mode so I could properly show it off. Basically I have a file on my local machine. And in Emacs I have a file that looks like this:

    #+BEGIN_SRC sh :results output :exports
    both :dir /ssh:joshua@richardrahl:/home/joshua ls
    #+END_SRC

    #+RESULTS:
    : dead.letter grep

Emacs is using tramp to ssh onto my remote machine, and show the contents. Nifty eh?

This basically amounted to me modifying /etc/hosts/ to make richardrahl point to my linode. I also used ssh-copy-id to copy my gpg key to that linode. It's pretty spectacular!
