What cloud computing really means
This article offered the following definitions in it's explanation of Cloud computing:
SaaS - A type of cloud computing that delivers a single application through the browser to thousands of customers.
Utility computing - This form of cloud computing is getting new life from Amazon.com, Sun, IBM, and others who now offer storage and virtual servers that IT can access on demand. Early enterprise adopters mainly use utility computing for supplemental, non-mission-critical needs,
Web services - Closely related to SaaS, Web service providers offer APIs that allow developers to exploit functionality.
Platform as a service - Another SaaS variation, this form of cloud computing delivers development environments as a service
MSP (managed service providers) - One of the oldest forms of cloud computing, a managed service is basically an application exposed to IT rather than to end-users.
Service commerce platforms - A hybrid of SaaS and MSP, this cloud computing service offers a service hub that users interact with.
Internet integration - The integration of cloud-based services is in its early days.

Christopher Barnatt explains that cloud computing is closely related to web 2.0. He explains that the whole idea is to offer software as a service that you use on your browser and don't install into your own computer. He also introduced the idea of Hardware as a service (hsas)
The Davinci Institute
"Throughout history the role of the library was to serve as a storehouse, an archive of manuscripts, art, and important documents. The library was the center of information revered by most because each contained the foundational building blocks of information for all humanity."
Here are the trends that are affecting Library services today:
1 - Communication systems are continually changing the way people access information
2 - All technology ends. All technologies commonly used today will be replaced by something new.
3 - We haven’t yet reached the ultimate small particle for storage. But soon.
4 - Search Technology will become increasingly more complicated
5 - Time compression is changing the lifestyle of library patrons
6 - Over time we will be transitioning to a verbal society
7 - The demand for global information is growing exponentially
8 - The Stage is being set for a new era of Global Systems
9 – We are transitioning from a product-based economy to an experience based economy
10 - Libraries will transition from a center of information to a center of culture
Recommendations for Libraries:
1) Embrace new information technologies.
2) Create a technology advisory board and stay in close communication with them
3) Preserve the memories of your own communities.
4) Experiment with creative spaces. " Our best advice is to enjoy the journey and relish in the wonderment of what tomorrow may bring. "

Week 13 Notes
No Place to Hide
Wow! Everywhere we go we're being watched? The guy watching me must be board out of his mind! How does this affect the business of Library and information Science? Is someone checking on what we "check out?" Are libraries going to be required to allow government agencies access to their computers? What will happen if you check out a book on Stalin? Or Terrorism? Or anti-government movements? This doesn't seem very American to me.Total "Terrorism" Information Awareness (TIA)
The idea that the government is sifting through databases looking at personal information is a bit too 1984 for me. I understand that our country fears another major terrorist attack like 9/11. I fear it too. I agree that efforts must be made to avoid that possibility. I do not believe that our personal liberties should be given up in order to protect us. No, I don't mind going through all of the security at the air port, and the ramifications of the patriot act irritate me only slightly when I am doing my banking, but further sharing of my private information...where will it lead?YouTube
Believe it or not "This video is no longer available due to a copyright claim by Viacom International Inc." That sends its own kind of message. This would be a good discussion for lis2000.

Week 12 Notes
How a ragtag band of created Wikipedia
This video presentation was very good at explaining how Wikipedia is created and maintained. I don't understand why some scholars are still so anti-wiki. I thought the "neoNazi math statement was pretty funny too!
The two articles for which links were provided to the ALA are not appearing...

Week 11 Notes
Digital Libraries - Challenges and Influential Work
This article began to explain what a digital library is and how it works. The Federated Search Diagram was very helpful in the explanation. I also thought very relevant the idea that there is a huge difference between providing access to discrete sets of digital collections and providing actual digital library services. Some of the technologies that Pitt provides, such as "Ask a Librarian" and having Librarians man Instant messaging is a step in that direction.
This article also explained the importance that federally supported projects have played in the development of Digital libraries.
Dewey Meets Turing
I learned several things in the article, the most interesting to me was that the The Google search engine emerged from the funded work of the Digital Libraries Initiative (DLI) . It certainly has changed the world's approach to information.
This article goes on to describe how the DLI affected both scientist and librarians in some positive ways and that the wrench that was throw into the mix was actually the World Wide Web. Where the scientist readily absorbed the introduction of the WWW, Librarians had a harder time because the WWW blurred the definition of information provider and information user.
Both groups have regrouped and many see the introduction of the WWW now as an asset and less as a threat.
Institutional Repositories
The development of institutional repositories emerged in 2002. "A university-based institutional repository is a set of services that a university offers to the members of its community for the management and dissemination of digital materials created by the institution and its community members." I see this as what Pitt has done with Panapto, BlackBoard, PittPay, etc. Providing services digitally. Services that evolve along with the student and university, not simply a software program.

Week 10 Notes
David Hawking , Web Search Engines:Part 1&2
Current developments and future trends for the OAI protocol for metadata harvesting. Library Trends
Michael Bergman, “The Deep Web: Surfacing Hidden Value”
These three articles were very informative and interesting. They brought a lot of insight to what I do nearly every day - search the web.
Part 1 of the first article relayed how the ideas of search engines have changes over the years. They have improved greatly. The explanation of the infrastructure and the illustrations of the generic search engine greatly helped my understanding. I also thought the explanation of why some information is not fetched was good. "Before fetching a page from a site, a crawler must fetch that site's robots.txt file to determine whether the webmaster has specified that some or all of the site should not be crawled." This was new to me.Part 2 on the indexing algorithms was more technical and I was glad again for the graphics.
Of all of the articles, I particularly liked Bergman's comparing a web search engine to a net going over the ocean. This brought to mind a very clear picture, even before I got to the graphic. The "deep web" is information packed, but right now our access to it is limited by most search engines.
