Computer Science Lockdown Quiz

This vid is just a fun quiz based on computer science and computers in general.

Images are from Wikipedia, except for:
Sound from final question from SoundBible:

As soon as you said "This next one is going to be a sound" I knew it was going to be the dial up modem haha. Thanks for this wonderful time!

The actual teapot was taller. An non-square aspect ratio in the 3D coordinates caused it to get this shape

I managed 29, heavily aided by being old enough to remember the first moon landings, let alone dial up modems.

26, but with a few lucky guesses. I've heard several times that the Apollo had less computing power than a [Game Boy, etc.], but I had no idea it had only 4kb of RAM! Very fun, thank you!

That modem noise brings me back. It's a 56k modem. In this particular audio clip, the calling modem stops transmitting after the handshake causing the host modem to try to renegotiate.

Lena compression:
if first bit is 1: output Lena picture
Else, next bits are the image data

28/30. I wanted to answer Wozniak twice. And somehow I had in mind they were basically flying with a C64 to the moon, but it was even less memory, impressive. RIP John Conway.

Turing did not discover the weakness of the Enigma machine. The weakness was discovered by the Polish cryptographers Zygalski and Rejewski. Zygalski invented a method for cracking an earlier version of the Enigma machine using pairs of perforated sheets of paper. But the method did not work for later version of the Enigma machine. What Turing did was he developed a method of adapting the Zygalski and Rejewski analysis into a machine called the Bombe which could crack the more sophisticated versions of the Enigma machine.

The 3.5 inch floppy was indeed originally specced to hold 1.44mb of data. However, some companies developed drives that could cram 2.88mb onto those discs.

Cool quiz apart from Alan Turing not discovering anything but just formalising the findings of Polish cryptographers.

17 year old american high school CS nerd here. I got a 22/30, or 77.5% which translates to a C+ on the american grading standard. If only I could get one more + on there... Had lots of fun and learned lots of new things! Thanks for putting this video up and I hope to see more like it!

As always, everything what you do is very good, please never stop. Greetings from Argentina!

Chris signed ya up on patreon man your material is just priceless shear gold. The time and effort you put into the videos deserves a return. Look forward to the next vid mate.

Lovely to see the little Neal Stephenson shout-out at 8:20; the reason I know most of what I know about Turing. :)

[LFSDK]

As soon as you said it was gonna be a sound question, I knew it would be a modem dial-up

[Concentrum]

by far the most humorous computer science related channel. love your stuff.

[sohamkar]

28! Didn't get the ENIAC and Utah teapot ones. In fact, I'd never even heard of the Utah teapot, I guessed Seattle because it sounded more tech-y.

[YuriyDavygora]

You're honestly telling me that Eric Idle, the author of the Python language, was not the father of information theory, Bruce? I'm gonna fishslap you while I'm dancing!

[arirahikkala]

7:30 Maybe I'm old-fashioned, but I would have specified that this is in two's complement.

10:50 Her name's actually spelled with one "n". She endorsed the misspelling because she wanted English-speaking people to pronounce her name correctly.

Oh, I remember seeing the 2020 Jimmy Carr lockdown quiz! I somehow missed this video when you made it.
