How Internet Infrastructure Works:
-NOBODY owns the internet
-mainly connection of networks, (fun, simple, colourful image)
-beginnings=1969, "grown from four host computer systems to tens of millions"
-not owned but nonprofit group formed in 1992 defines how we use and interact with the Internet.
-Every computer connected to the internet is setup to a network; in each region, a company has a Point of Presence (POP)- place for local users to access the company's network, there is no overall controlling network but several high-level networks connecting to each other through Network Access Points (NAPs).
-Provides example of network and its connections; "The routers determine where to send information from one computer to another. Routers are specialized computers that send your messages and those of every other Internet user speeding to their destinations along thousands of pathways." (fun image of router, switches, and internet)
-Internet Backbone- first one created 1987 by National Science Foundation, basically fiber optic truck lines for transmission of information
- IP Address= unique id number, really in binary but set up decimal number for humans
-1983, the University of Wisconsin created the Domain Name System (DNS), which maps text names to IP addresses automatically
-Top-level domain names, also called first-level domain names, include .COM, .ORG, .NET, .EDU and .GOV
-Networks, routers, NAPs, ISPs, DNS and powerful servers all make the Internet possible
-simple to use, thankfully, the internet can provide information around the world in a matter of milliseconds
-contains links to related articles, naturally from howstuffworks
Dismantling Integrated Library Systems:
Article is about the transition from traditional ILS system to that of a digital form. While the internet may create a better form in time, the transition is proving to be difficult and messy, causing some to be concerned with the loss of information. There are issues of what to choose, vendors, formats, competition, costs. "Some of the best ideas in online library services have come not from vendors but from librarians themselves." This is not surprising since it is the librarian that most work with the system and the patron. Mentions the concept of chicken vs. egg in that no one knows who caused the proliferation of new library automation modules. While these advancements are beneficial to the library and patron seeking information and networked communication and the technology is of a much better quality now than when this article was written, I still have a problem with some resources, such as BlackBoard (courseweb) and their overuse.
Sergey Brin and Larry Page: Inside the Google machine:
-“ Google co-founders Larry Page and Sergey Brin offer a peek inside the Google machine”
-filmed 4/2004, twenty minutes long
-the answer is boxers, haha…- assume joke perhaps based on Clinton campaign interview on MTV where the question was boxers or briefs, haha
-revolving glowing globe display, show data connections
-Las Ketchup in 2002 popularity example
-the Google foundation
-Orkut
-Googlette
-according to comment, Google answer no longer exists
-cult picture funny, I want to work for Google for the sky trip!
-its crazy to think of all the services Google provides, including the phone product that will soon be released

I really like your usage of "bulleting" the key points.
Really helpful when reading difficult material.
Isnt it crazy to imagine that the internet started with 4 computers and is now just everywhere-like a parasite or something.
Ditto w/ your feelings about Bb and it's overuse. It was nice when it was a new thing for Professors to use, but now...it's getting kind of annoying to use when there are many other better programs Professors can use in it's place.
Hi John,
(First, I wanted to second what umm_ibrahim said about the readability of your blog--the bullets are really helpful for readers!!!)
I wanted to know what your problems with Blackboard are and how you think they could be better addressed. I also find Blackboard to be problematic and frustrating quite often, but at the same time, I don't know what else professors and instructors could use in Blackboard's place. Any thoughts? For all of BB's issues, the fact that it can exist as a collaborative place is particularly helpful in a blended class such as this class.
You have a good point that many times innovations come from librarians rather than the vendors. In my experience, sometimes people who program things don't have the resources or experience to think about what the user will want to do. And also, what seems clear on the programmer or vendor's end, is not at all clear on the user's.
