Love how this guy's voice pitch increases towards the end of a sentence :D

for months and months I defended that brown paper - now you all change your tune!

I love how in order to opt out from cookies on a site, the site needs to save a cookie

Hmmm. I checked and the Jaffa Cakes official site uses cookies. So much for them being cakes.

Thanks - it was Sean who got his hands on that! Makes me all nostalgic. >Brady

What a wonderful accent!!!

Very strong start to the new channel. I congratulate Brady and Sean, good job so far mates!

Is that paper for a dot matrix printer?, wow that still exists ;)

"hello" Of course, with a amazing accent.

Awesome video! Really glad your touching on topics like this Brady. I work in IT and it can be difficult for people to understand these simple concepts. I hope you do more things like this in the future!

Awesome episode. I can't wait for more!

This was really insightful. I love the new channel. Keep up the great work

I already know everything that this video is about, but I did learn a new phrase: "usen't to be", as in "it usen't to happen before". Thanks Brady, your videos are indeed always educational!

It makes me feel great when after watching all the other channels, I TRY to understand. But this channel, I know everything already

Very good video, love the new channel. Keep it up

Thax Bradty! I love the new canal! And the new paper....

Great explanation, subscribed and will watch the rest, thanks.

Very nice videos, computerphile ! :D

Amazing video Sean!!

Glad to hear, mine is currently running a mame arcade machine in my backyard! looking forward to seeing more videos, keep up the good work

Brady, you are truly great.

I've seen all of the computerphile videos like a boss

cannot unhear it now

Loving the new channel Brady. Yous should see if you can do something on the raspberry pi at some stage, so much good content to talk about on it. Thanks for all your awesome videos! they get e through the week!!!

Loving this series so far, fantastic work. I'm sure you will eventually but topics I'd like to see are: Bits, bytes etc Computer architectures Instruction sets CPU cores, threads Clock speeds Programming levels and languages Servers and networking

Very informative, thanks! I'm curious if there will there be videos on more computer science-y subjects?

Brady, please do a video about the different programming languages their origins and history!

He needs to say cookie crisp... lol Great Vid! Good job on the new channel, Brady!

Great, more like this please. The concepts around computing.

You guys are doing a great job :)

A cookie is a file a webpage can create on your computer and reference in a separate session. A common way of doing this is when you visit a webpage it checks if you have a cookie, if not it creates one and gives you a unique tag, it can then gather information on your actions and save it on the web server with a reference to your unique id, when you visit the page again it finds you have a cookie and looks up what information it gathered last time you were there. Hope this makes sense

I'd love to see some documentation of that - I can't seem to find it.

I love his voicecracks :D

So that's why i've been getting the hardware store site commercials on the side of the video player after i've been searching through graphics cards on the site.

fixed now, apologies for the delay! >Sean

we will be looking at programming soon >Sean

Thanks for letting us know.

Yeah! And the green on black with terminal fonts is very nice and nostalgic touch also!!!

Oh my gosh that accent. This is going to be a good channel

Tom has a Scottish accent

Thanks for the info. I still use Ghostery, and I also use it as a set-and-forget solution. The only thing that is a bit tedious is that when you click on a blocked redirect, it completely unblocks this tracker forever, not only this one time. But once you know that, it's fine. I also started using NoScript, but I have set it up in a way that it doesn't bug me and allows the scripts that are needed for a page to work, without me having to sort out which scripts these are, and which aren't needed.

You could also block ads using the hosts file. Its a bit tricky but universally works on everything.

fixed now - sorry for the delay >Sean

I like you using infinite printer paper for computerphile, it gives that vintage computer feel and provokes that specific sound of dot matrix printers.

The browser cache store images, style sheets and other static information that only need to be loaded once and a browser never send anything from the cache back to the server. The cookie on the other hand is a small piece of information that is sent back and forth between the server and browser on each page load, typically a session id or page preferences.

I love the vintage format with green-on-black graphics and old-school printer paper!

This channel is so awesome :p

Nice overview of the basic server client relationship for cookies. More in depth security videos would be nice as well, including bots and crawlers. A lot of this stuff is going to come into play more and more as we become more connected with our technologies. Third party cookies are actually one of the minor culprits at the moment.

Can't wait for the musical drives! By the way, may I know what accent is Tom speaking in?

It's not a barrel, it's the database image used in the computer world for diagrams. It's meant as "a place where data can be stored".

Actually it is 'music lined' green and white striped tractor feed computer paper... >Sean

The Collusion add-on for Firefox shows these connections really well.

On TechMeShow we were showing how they're tracking you, doing fingerprinting and I think you guys should cover fingerprinting as that's the new age cookie aka tracker.

Raspberry Pi is on the list - quite high up actually! >Sean

Thanks for doing Computerphile. You have quite a lot channels, isn't it very hard work to manage all these channels? Do you have time left to do other stuff than that?^^

I like the choise of paper for this series :)

It is kind of mentioned when he uses the ticket and shoes explanation, but yes it still lacks a bit.

Can you guys do a video on encryption and cryptography? One of my compulsory modules for university next year (my final year) is Cryptography, and it would be great to get a headstart in the matter! Thanks!

I've always loved the brown paper. Don't stop using it!

All major browsers need permission for each individual page/web-address to access the webcam or microphone

and this is why i clear my cookie chain every so often by hand.

Is the connected printer paper going to be replacement for brown paper in this series?

I would love a follow-along type how-to video about writing a program.

can you do series on how to programme from basic to complex

This guy has an amazing inflection in his voice :D ...Also good video; that's probably more important.

I'm waiting for it to be good enough that they'll stop giving me ads for cars I can't afford.

I'm really starting to love the computerphile graphics (the green on black)

Another great video Brady! That guy has a cool accent btw...

Like others have said, I think it would be very useful to have a part two about cookie preferences in browsers and related privacy topics (blocking third-party cookies, Do Not Track, AdBlockPlus and NoScript, and so on). I'd love to have a nice video that I could show to my non-tech friends.

I could listen to him say "Here is a page," all day.

actually you can store information in cookies, however some developers prefer to just store an identification number in the cookie that reside on the client side and store the related information in a file or a database on the sever side. in this case it is called session-based cookie.

Thanks!

At around 3:07, did he say "usen't"? I would be so happy if that became standard practice.

10 style points for using the old school fan fold paper.

Computerphile, you need to use this guy more often xD

You can disable adblocker for particular websites. I don't know if you can do it for a YT channel though.

Would like to know more about that.

I love this guy's accent when he says world wide web

Wow this guy's voice ... breaking in to higher pitch all the time at the end of phrases.

You should do a video on the different operating systems (Apple, Windows, Linux etc)!

his voice is amazing

Would also love to see some brown paper. Waiting patiently.

I did notice the voice was different. You should introduce us to Sean (perhaps you have and I missed it). I see now he's credited for making the video.

can you make a video about the history of programming?

Ok, so to make sure I'm understanding this correctly first, cookies allow websites to remember information about you by having YOU store information about your activates right? So if websites are going to "recall" those memories, they will have to query your system to find out if you have this or that cookie, correct? What stops website A from checking for website B's cookies, and getting information you didn't give to them?

Wait, is the cookie moving in the right direction in the animation? I thought the cookie was from the PC to the server, as it's stored on the PC and the server is still "state less" (for this example anyhow).

Your browser cache is like a collection of photocopies of old web pages you've visited so your computer can load content from them without having to request it again from the website the next time you visit a page. Websites don't look at your cache since there's nothing there that they want; it's just a bunch of html's. Cookies are text files that are made by the web page and stored locally on your computer. tl;dr: Your computer wants to remember the cache; websites want to remember cookies.

Have you go into much in the way of code? I learned most of my code basics from ROBLOX. While I wouldn't use it now (i have blender), it helped me a lot. (any other scraps of code i learned came from action script)

It keeps a list (that's being updated regularly) of domains that ad's are served from. Those domains are for example owned by companies that serve ads. If you block them and not the KZread domains from which video's are served from, then you can tell the difference between ads and video's. Note that it's not a perfect system though.

There is an easy way of deciding this matter: X is a programming language if and only if you can write a Turing machine with it.

It's the accent of Lister, Baird and Bell, so yes, it is awesome indeed.

I love the use of the computer paper instead of the usual brown paper

The dot matrix printer paper, instead of butcher's paper, is a nice touch.

I don't mind personalized adverts. Ads serve an important purpose to us, letting us know which products and services exist. If it is possible for the ads that I see to be about topics I am interested in, the ads start to actually benefit me, allowing me to take them more seriously and actually watch/read them. The old model of showing ads indiscriminately to huge masses is inefficient for both advertisers as well as viewers, since our time is wasted on things we are not interested in.

Cookies warning on webpages are a nightmare on a mobile browser. They frequently float around blocking the content. You can't close it because it floats to the top.

Did anyone understand what he said at 0:40?

I always liked the brown paper for numberphile, though I also really like this new paper for computerphile. Keep in mind that only a fraction will talk about what they like or don't like. And typically, the fraction that doesn't likes things is louder than the fraction that likes things. If you change something like that, you'll hear a lot of voices you hadn't ever heard before, concerning the topic.

"There you GOO"

Ads have never worked on me. I have never bought anything because of an ad, let alone clicked one and bought the thing advertised.

We are dipping our toes in the arduino 'waters' in the next video, more in depth on them in the near future...
