I wanted to export my playlists with Plex, I installed Export Tools and ended up with CSV files.

I looked around and couldn't find something to convert those to m3u. I did get a m3u8 file but it didn't work with my devices...

I made a quick python script to convert the csv to m3u...it's possibly useful to someone else...maybe.


#!/usr/bin/env python

import csv
import getopt
import sys


I find this really useful, just a call out to sed so I don't have to remember the syntax.


ssh_delete_key() {
sed -i -e ${1}d ~/.ssh/known_hosts
}
alias sshdel=ssh_delete_key


While at LinuxFest Northwest I picked up an Old Raspberry Pi from the Yard Sale. I didn't realise it was a Model A...took me a while to figure out a use for it, not much memory or processing power.


I use a USB camera on my work laptop and the camera sometimes doesn't show up in my video conferencing app. I verified that the camera is showing in the usb list with lsusb (a script I got from https://github.com/jlhonora/lsusb which is great btw).

dtruss showed that the VDCAssistant was being accessed by my apps, so I tried killing that and boom the camera shows up.

So now I aliased camkill='sudo pkill VDCAssistant'


I spent far too long diagnosing why this worked in one set of hosts and not another. When the vrrp_script fails on one host, it's supposed to move the service to the other host, that's the whole point right?

Some of this isn't a great idea for production...some.


Had a problem where I wanted to modify /etc/cups/cupsd.conf but wasn't sure who else might touch the file. I opted to use Augeas and quickly learned it wasn't as easy as I thought it might be...

The cupsd.conf configuration file uses a syntax similar to Apache configuration files, it uses the same Augeas lens (Httpd.lns). Changing directives is a bit of an issue, but I found the solution by reading the source for the Httpd.lns (/usr/share/augeas/lenses/dist/httpd.aug or /opt/puppetlabs/puppet/share/augeas/lenses/dist/httpd.aug)


I ran into this problem recently, certificates were verifying ok but were revoked somewhere along the line. I wanted to check against the CRL but it's a somewhat undocumented feature (fixed in openssl 1.0.2). The -crl_check option checks your cert against the CRL listed in the certificate, but only if that is listed and accessible remotely.
