Extension lecture introducing steganography (hidden messages). Security via obscurity. Hidden messages in book Godel Escher Bach. In film Starship Troopers. In games. In cryptography. In teaching. Digital watermarking. SETI. Are we in a simulation? Extension lectures are for first year computing students at UNSW. The topics covered are non-examinable, students attend only if they are interested. Richard generally raises more questions than he answers.

Damn! Just when it was getting really good, it’s over! Booo.
Good Video. : )
thank you sooooooooooo much
Are videos 31a and 31b meant to be flagged as private?
Thank you for the info. I had studied “Cryptography and Network Security: Principles and Practice, Second Edition. by William Stallings” in engineering and also went through few chapters of Applied Cryptography. Both of which I had liked a lot.
Thank you for the recommendations. I will get “The Codebreakers” first. Have a nice day!
Yes Kahn’s brilliant book is “The Codebreakers” and is the best book on the history and principles of cryptography I’ve had the pleasure to read. The Code Book is another popular book on codes but i’ve not read it, quite a few of my students like it however. A book I can strong recommend is “Decrypted Secrets” by FL Bauer, and of course Applied Cryptography by Bruce Schneier is a brilliant introduction to the field since the second world war.
Shouldn’t the book be “The Codebreaker” by David Khan.. And not “The Code Book”..??
I am confused..
I am so jealous of this class… In my school they teach as really ancient stuff (like pascal)
I hope we’ll learn in a more accelerated way @ uni
Can you please come to london and teach my Forensic course, i’ve learnt more in this 30mins than i have in a year at my uni, thanks!
u must read this.one u have started there is no turning back.a little 10 year old girl was raped and murderded in 1945.her body was not found until 1947.then a boy last week read this and did not copy and paste this message.the dead girl appeared in his room haunting him and killed him. if you do not copy and paste? this onto 10 vidoes in 30 minutes the dead girl will appear in your room tonight and haunt you and kill you.well you better start to copy and paste to be saved not mine
This guy reminds me of John Green
hes emo
Marine Engineering.
And thermodynamics is one of the courses in it; I cant just choose to not take it.
i like the class
Is a good idea to bring the class in here this in case of of the studens are in a hospital sick, etc, we could not be missing clases, good job !!
what degree are you doing? thermodynamics is interesting. if you dont like them why you take it. not having a go man just interested to know what you doing because i take those too
Yeah! They’re learning about steganography etc, all I’m being tought is advanced mathematics, thermodyanamics etc..all the boring crap in one!
Does anyone here by any chance know what program/line (idk the name) these guys are studiying in this uni.?
i swear people like this get paid per comment and rating?
Awesome!
Australia.. What exciting schools overthere, man. excellent! (*^-^)b
yawn
you are a tard
Excelent video… Thanks for the post!!!
What a cool teacher! Wish my uni teachers taught as enthusiastically as he does.
Cool content too.
this has been taking me about 2 hours to finish since i kept pausing
