Some post-conference extras for the Wall Challenges...
Thanks to everyone who entered the Wall Challenges!
The concept of giving the answer away right at the start, and then making the challenge explaining 'why' each question led to that answer, seemed to be very popular! We got more than twice the number of entries compared to the previous Wall Challenge. The email inbox was very busy - there were 65 emails from entrants. And the Discord channel was melodious and mellifluous (and not discordant!).
Questions
If you didn't enter, and want to get the same experience, here are just the 'questions':

Just pause the video whilst you think...
Answers
And if you want to know the 'whys', then here are the 'answers':

One final thought about the entries: If there had been a prize for 'Most beautifully and clearly laid-out entry', then
Loïse from Brightsight would have won... Unfortunately there was only one prize (for the winner), but my congratulations for a very organised answer!
Resources
Some entrants did more than just explain why the answer is connected to the question, they provided links to online resources that they used as well. Here are a couple of links to explore:
https://gchq.github.io/CyberChef/
CyberChef is a brilliant toolkit for transforming text (and data) in many ways. It makes all sorts of interesting processing quick and easy to carry out, and can save lots of paper and pencil sharpening. The source is a very good indicator of just why Wall Challenges are 'Security Training in Disguise'.
👍👍👍👍👍 (5 thumbs-up!)
https://www.dcode.fr/en
dCode is another set of excellent tools that can be very useful in manipulating text and data - plus a lot of other miscellaneous operations and functions.
👍👍👍👍👍 (5 thumbs-up!)
Both of these should definitely be in your toolkit!
Oh, yes, and I can neither confirm nor deny that I may have used some of these online resources (as well as paper, pencil and pen) to create the challenges...
https://www.rapidtables.com/convert/number/decimal-to-binary.html
Not quite in the same league as the above two examples, but still useful...
👍👍👍 (3 thumbs-up!)
Previously on Wall Challenges...
There are more wall challenges, door quizzes and wall games that I have produced over the years. Caution: many of these are considerably more difficult than the ones above.
If you browse through my YouTube channel, then you will find even more challenges... (No prizes!)
Ah!
Yep. There's a deliberate error in the example question shown at the start of this blog post. Can you figure out what it is? There's a clue in the picture...
