Definition of a LAN, with pictures. The Internet can be thought of as a network of LANs.

Okay, here's a picture that roughly approximates how people used to interact with the Internet before there was a Web. All through text, all through a CLI (command-line interface). I started grad school in 1992 and this is pretty much what we had. This too is what that 1988 Washington Post article is thinking of when it talks about Internet.

Oddly enough, today the Washington Post has chosen to reprint a 1988 article about the Internet; that article mentions Robert Tappan Morris, the first person prosecuted under the Computer Fraud Act, whom Brittney Douress told us about today. Nice timing, Brittney! :)

Note too that this article came out well before the World Wide Web was invented circa 1992 / 1993. There weren't any GUI web browsers yet; people just used text-only terminals (no pictures, no video) to access stuff. Mostly news groups -- I'll post a picture of what that looked like if I can find one.

Madalyn's presentation informed all of us on how Instagram started and about its founder, Kevin Systrom. This article explains to new feature of Instagram. Now your followers can view photos that other people have uploaded and you can be tagged in photos as well.

This a great website not only describing how web crawlers work, but how you can create on your own. Descriptions and pictures really help to create one if your stuck too.

That is a good tutorial -- thanks, Gordon. My own PHP skills are good enough to build this, though at the moment I don't need to. I had forgotten the synonym "scrapers," too. Useful quotation: "One typical task that Google performs is to pull all the links from a page and see which sites they are endorsing."

Here's a great story related to the issue Milan raised of authenticity in photographs -- during any disaster, lots of fake photos circulate, such as these "from" Superstorm Sandy.

This is just a fun YouTube video with examples of altered pictures. This shows all the aspects of Photoshop and the tools that can be used to deceive viewers. Many are obvious, but some make you double-take.

Just for fun, a story about James Van der Beek guy who was on "Dawson's Creek," which was *THE* hot show in 1998, and some of the differences between being famous then and being famous now. On the one hand, you're more exposed now (thanks, iPhone); on the other hand, there are more ways to make pieces of 'the real you' public: " At least on Twitter, I put out some bits of my sense of humor. Whereas in '98, when I was being mobbed by girls, they were just looking to go crazy about anything and could use the excuse, you know, to scream and go mad." Just FYI, I myself have never seen Dawson's Creek, but I remember when it was big, and I know someone who's rewatching all the episodes on Netflix now and live-tweeting them.
