I’m a simple man... I see Dr. Mike Pound, I click
-
looks like Alice and Bob are in quarantine like the rest of us :)
-
Mike is my favorite expert on Computerphile. The way he explains things about security is very clear, but also has some useful historical facts.
-
Please do a video on Macromedia Flash - How it worked, how it affected Internet culture and why it's being deprecated.

5:47 If you think about it, the OSI seven-layer model included a “presentation” layer, between “transport” and “application”, that nobody could fit into the reality of TCP/IP very well. But SSL/TLS fills that layer very nicely.
-
we are actually using TLS to learn TLS if you think about it
-
Dr Mike Pound is my favorite scientist on Computerphile. Also IMHO the best teacher in this domain on YouTube.

Ah, yes... the 90s. Great computer times. We had hubs instead of routers. Blasting all the data to all the port, hoping that only the intended recipient would actually grab it. Or token-ring networks, even worse. With the right tools, you could just grab all the data that was intended for other users in the network, like chats, visited websites, video stream. Fun times...

Having been one of the original designers of the ISO 7 layer model - I find this fascinating (way back before it was known as the 7 layered model {middle/late 1970's}) . My - how far we've progressed! We had no idea that internet/ATM/streaming TV etc would eventually manifest from our ideas.

Seeing the Netscape browser makes me so nostalgic! My first time using the internet at age 20 :)
-
Technically TCP layer packages its data in segments and the IP layer uses datagrams. Sometimes people get confused when the term packet gets used to represent things at the different layers.
-
Great intro! Would love to see DTLS & TLS 1.3 covered in the future!
-
The "history lesson" in the first half was extremely helpful. I find it much easier to understand concepts and that they are much stickier in the memory with the story. thanks
-
can't stress enough how mike's history lessons are the reason why we understand so much from him :-)
-
Mike is always my favourite guest
-
Thank you for this video. Im a networking student and theres all sorts of little tidbits that professors miss (they only have so many hours for lectures). I'm truely grateful for this channel as a whole.
-
The world needs the part 2 of this video! Nicely done guys!
-
Mike: very, very clever. Sean: Does it ever go wrong? Mike: yes! All the time 14:12

Another entertaining and educational Computerphile. Each academic has an interesting style and presentation, if Mike Pound is not just research-based but takes the odd class, It would be interesting to watch a vox pop from a cohort of his students to see if they enjoy his classes as much as I enjoy his presentation style. There could well be a whole documentary lurking in the background based on following the presenters over a semester. Their challenges of funding, hierarchy, student and staff interaction, the production of Computerphile, resources, and more. 👀

Roll on the next video! What would I do without DR. Pound's knowledge and Sean's great questions - thanks guys :)
