I'd like to give a huge "Thank You" to Ralph for presenting on MediaWiki last night. He did a great job! A little background, a live demo, even hands-on audience participation to show how vulnerable a default MediaWiki server can be! We figured out step 1 on how to secure it at the LUSH afterwards, and so our new site should be up soon (hopefully by the end of next week).
Rob.

Sounds great!
Continuing on in that vein, here's a possible future topic: the
LibreElec distro.
LibreElec is a canned spin designed to power a media center. It works
very well on the Raspberry Pi, although also on other platforms.
As part of my Hurricane Kit, I have a Pi with LibreElec and a 7-inch
touchscreen. Since it contains Kodi, that means that I can watch/record
over-the-air TV (using a USB tuner), play videos and music, and even
surf the web. One of the things it provides is a DLNA server so that
the Roku devices can tap into its media archives;
When a storm hits and the lights go out, I have a 12V UPS battery (12
amp-hours) that I can keep charged from a solar panel. I switch on the
Pi and change it from being a WiFi node to being a WiFi access point so
that portable devices can exploit my local entertainment archives and
the tuner can pull in local TV weather radar. I also put a copy of my
local ebook libraries on a LAN fileshare so that I can keep well-
supplied with reading material (one of the many reasons I only buy DRM-
free eBooks these days!)
So, in short, I can lead a quite civilised existence even when I'm
otherwise cut off from the rest of the world.
The whole thing is pretty easy to set up, since it's distributed as a
ISO image. The only really gnarly part for me has been getting the USB
TV configured using TVHeadEnd, which is something best done from a
remote web browser. I also had to experiment with several antennas
because the Hauppage USB tuner isn't as sensitive as a stand-alone TV,
but the best one was only about $20 and can be stuck in a window.

This peaks my interest.. especially as a HAM radio operator. Would love to learn more about this topic.

"piques". Tow the line; your not allowed free reign when it comes to
spelling. Being a Nazi (grammar) is the "in" thing these days, you
know.
Actually I have a second Pi for radio. The Pi/Linux has a wealth of
radio software. My radio Pi has an RTL-SDR SDR unit, since the Hauppage
devices don't handle the proper frequency/mode combinations as well. I
can use that with FlDigi and its friends to monitor VHF/UHF, and I got
a VHF weather satellite interception kit, although haven't had success
with it, since you only have a short time of day to catch a bird and
the antenna needs to be taken outside.
For shortwave, I have a vintage iCOM PDR-1000 that I can use to catch
and display WEFAX transmissions from New Orleans, do VHF RTTY and Morse
decoding, whatever. I have a stand-alone Heathkit to allow me to
monitor the Hurricane Net simultaneously.
The biggest problem with a Pi is that the stock unit has only one jack
for both audio in and out which makes it hard to monitor the iCom's
line input, but this particular unit has a Cirrus Logic shield so it
has all sorts of audio options.
More recently an inexpensive Pi audio add-on is a digital adapter using
I2S. The Cirrus Logic is no longer manufactured, but I2S is cheaper and
doesn't need a full shield.
