## the_pentaverate.txt
Well it's a well-known fact sonny jim that there's a secret society of the five
wealthiest people in the world known as...The Pentaverate, who run everything in
the world, including the newspapers, and meet tri-annually at a secret country
mansion in colorado known as...The Meadows. The Queen, the Vatican, the Gettys,
the Rothchilds and Colonel Sanders before he went teats up. Oh I hated the colonel
with his wee beedy eyes and that smug look on his face `ohh you're gonna buy my
chicken ohhh`
- Dad how can you hate the colonel?
Because he puts an addictive chemical in his chicken that makes you crave it
fortnightly smart-arse!

## strip_harder.rb
# This was probably encountered and overcome a long time ago, but I ran into it in my own Ruby dealings and thought maybe it could be an issue elsewhere:

  #   definition of whitespace to match the encoding
  #   https://ruby-doc.org/core-2.6.8/String.html#method-i-strip
  #   String#strip removes lead/trail whitespace defined as: '\x00\t\n\v\f\r '

This is from an old presentation, I just wanted to record it somewhere. I'm not saying this stuff:
a) still works
b) is a good idea
c) hasn't been surpassed greatly in the last 7 years
d) is completely accurate

I just found this API ridiculously confusing to use, and maybe I just suck, but I don't want to figure it out again, so I'm writing it down here
Establish a gpg home dir if desired

Optional, but if you have an established gpg home dir that you want to use or you don't want it chosen for you
GPGME::Engine.home_dir = "/some/dir" # e.g. env['GNUPG_HOME']

                vmware tools problems such as mounting shares and kernel patches
              
          
    Restart vmware tools services


restart the services so you can see if any fail

sudo /etc/vmware-tools/services.sh restart

if failure, you can optionally check which services are actually still running

sudo /etc/vmware-tools/services.sh status

but you'll want to rerun the vmware config script which will recompile kernel mods
