I'm trolling a bit, so I guess I don't care that much... but I do a bit though... does it show that I have a chaotic brain?)

Kevie, co-host of TuxJam, discusses what a Dynamic DNS is and also introduces the free service DuckDNS. To complete this project you are going to need:
The first thing that we will need to do is to go to the DuckDNS website, sign in using your preferred method, once you complete the captcha then you will be given your unique token (copy or take a note of it, but don't share this with anybody).
Next you will want to create your own unique address, type in your chosen domain and click on Add Domain.
Now it is time to setup your Raspberry Pi. Log into your Pi and open a terminal. The first thing that we will do is make sure that it is up to date:
sudo apt update && sudo apt upgrade -y
Install Curl using the command:
sudo apt install curl
You will now create two new folders, the first is where the script will be kept, the second to store the logs:
sudo mkdir /opt/duckdns/ && sudo mkdir /var/log/duckdns/
We need to add a bash script that will update your IP with the DuckDNS service. First of all create a new file called duck.sh with the code:
sudo nano /opt/duckdns/duck.sh
At this point the file is empty, we need to enter in the command below. However you must replace DUCKDNSDOMAIN with the domain that was created on the DuckDNS website and replace DUCKTOKEN with your DuckDNS Token:
echo url="https://www.duckdns.org/update?domains=DUCKDNSDOMAIN&token=DUCKTOKEN&ip=" | curl -k -o /var/log/duckdns/duck.log -K -
Now save and exit (ctrl+X, Y, enter on Nano).
Next we can set the script's permission so that nobody else will gain access to your token:
sudo chmod 700 /opt/duckdns/duck.sh
Last step: we need to set a cron task so that your Pi will update DuckDNS domain every 5 minutes:
sudo crontab -e
Navigate to the bottom of the page and add the line:
*/5 * * * * /opt/duckdns/duck.sh >/dev/null 2>&1
Save and exit and your dynamic DNS should be up and running within five minutes.

Picture 1
shows the radio hanging over the edge with the front panel rotated down
before rotating it back into place. It shows the cramped working
condition I had to deal with.
Link to the YouTube video I used that described the process of removing the two backup batteries in a Kenwood TS-940S. The video was very useful and informative however as usual it looked far easier than it actually was or perhaps I’m just rubbish at taking radios apart.
Picture 2
shows the clock display immediately after first switch on with the
display not working properly.
Picture 3
shows the correct clock display after pushing an internal reset button.
I think the picture shows the alarm and timer settings. It eventually
displays the correct time once it was setup. Unfortunately I forgot to
take a picture of the final clock display.

date commandcron job to refresh
the site every three hours. Each show page shows the refresh time in UTC
form in the header.date command accepts a date and time expression
after the -d option (or using the
alternative--date=STRING option). The contents of the
STRING here are very flexible but quite complex since you
can include time zone data, offsets, day and month names, etc. See the
links below for links to the GNU manual.date command like this and
got the wrong answer (using the output format +%T which
writes the time in a default form): $ date -d '16:27:16 + 3 hours' +%T
15:27:16 $ date -d '16:27:16 UTC + 3 hours' +%T
20:27:16date
command has added three hours to the UTC date to get 19:27:16, but since
I am in the UK, which is in DST (called BST - British Summer Time - UTC
plus 1 hour), an hour is added.-u option which writes UTC
time: $ date -u -d '16:27:16 UTC + 3 hours' +%T
19:27:16 $ current='06:27:55'
$ next=$(date -u -d "${current}UTC + 3 hours 3 minutes" +%T); echo "$next UTC / $(date -d "${next} UTC" +'%T %Z')"

15:36:55 UTC / 16:36:55 BSTpastepaste as an alternative way of doing this.paste command is another from the GNU
Coreutils group. This one merges lines of files. Its synopsis
is: paste [OPTION]... [FILE]...- (hyphen) as the file name.-d LIST or
--delimiters=LIST option. The use of a list of delimiters
causes the characters in the list to be used sequentially for each
delimiter.-s or
--serial option. Here the lines from one file at a time are
merged - the files are processed serially rather than in
parallel.paste command can be used to generate the
comma-delimited list I wanted by using the options -s and
-d ',': $ printf '%s\n' {1..10} | paste -s -d, -
1,2,3,4,5,6,7,8,9,10echo {1..10} because all the numbers will be written to one
line rather than being the separate lines that paste
requires.paste may also be Bash

This introduction is an overview of Doctor Who from its beginnings in 1963 right up to the end of 2023. We look at the television series and movies, as well as appearances in other media. Many of these will be things we go into more detail about later, but this helps to put the pieces in place first.
