Muddiest Points Zotero CiteuLike

This was an interesting assignment, but frustrating at the same time. I seemed to click buttons on "instinct", rather than really knowing what to do. The tutorials were not working for me. Thanks to Tamoul who explained how to add the "bib" extension to the files in Zotero. Thank you, Thank you.

I work on computers but in a narrow scope; here I learned to search, add and then import/export my 'library'. The use of 'import/export' terms seems strange; it has a business connotation to me, ie, import/export business, but probably makes sense because of the actions involved.

Readings Unit 6

I. Wikipedia:

A. Local Area Network - a computer network covering a small geographic area that has a much higher data-transfer rate. Worker OK but too many systems were sold by vendors with incompatible computer hardware.
B. Computer Network - a group of interconnected computers that can be classified to the hardware technology used to connect the individual devices in the network. There are different networks: Personal Area Network, Local Area Network, Computer Area Network, Metropolitan Area Network, Wide Area Network, Global Area Network (in development), Internetwork.
C. Basic Hardware Components - lots of information about what's used to interconnect network nodes. (more than I need to know)

II. Coyle K. Management of RFID in Libraries

-Can't ignore technology
-Not one but many different
-Different amounts of information can be contained in the tags used.
-Tags are cost saving as will be reused several times.
-Tags used for security
-May need different RFID's to fit different articles, books, magazines, Cd's/DVDs.

III. Videos

Common types of computer networks - short, interesting.

Multimedia Representation & Storage - Unit 5 Readings

Data Compression - Wikipedia:
-Process of making information take up less space.
-On the positive space it is useful by reducing the the use of space.
-On the negative side, when the compressed data is 'decompressed', some data may be lost.
-Two compressions described:
Lossless compression looks at eliminating repeated values to sent data concisely; this is reversible so original data can be retrieved.
Lossy data compression works on perception, can a part of something be eliminated but will the whole still be perceived? Here some data will be lost.

Data Compression Basics:
-Although states is not technical, is very technical, giving many examples.
-Advantage of data compression=lets you store more in the same space and transfer info in less time or with less bandwidth.
-Presented in 3 parts:
Part 1 describes the types of lossless data compression algorithms & techniques used to improve performance.
Part 2 describes techniques used in lossy compression (where data obtained after decompression is not necessarily identical to the original) and techniques adapted to improve lossless compression.
Part 3 describes how the concepts and techniques from the first two parts can be applied to video compression.

Imaging Pittsburgh:
This is an interesting article on the collaborative use of technology to provide access to both researchers and the general public to a website, created by three entities, showcasing photographic collections depicting the growth of Pittsburgh during the 19th and early 20th century. Through these images of Pittsburgh's people, neighborhoods, buildings, you can see the social, cultural and physical changes the city underwent. It's a good example of the work involved in preservation, not only of cost but of the choices faced by the group members regarding which images to display. It considers the matter of copyright and provides a link to the home website of each of the groups for further exploration.

YouTube and Libraries:
-As a visual tool for enhancing the services a library offers, it uses two of our sense, hearing and seeing to provide information. As a visual learner this appeals to me and I suspect will appeal to others as well. It can be used to reach a large number with a small amount of effort. That said, someone must decide what to include, when, where, how to film and then upload to the site. Supposedly it's biggest advantage is the ability to upload videos in any format. I haven't visited the site myself but plan to do so soon.

Hopefully this will work.

The tumbnail is 'fuzzy' to say the least and the screen image I couldn't figure out how to save. I will play with this again and try to upload better images!

Database, Metadata & Dublin Core Data Model

Database:

-Structured collection of data
-Relies on database management system 'DBMS' to organize, retrieve stored data.
-First developed in '60s. I didn't know this, thought it was earlier, but don't know why I thought this.
-Different structures to 'hold' data:
hierarchial, network, relational
-Technical term definitions related to the design of databases. More than I needed.
-Application, to me the most important topic, is discussed at the end.
-Preferred method os storage for many applications. I believe the system I use at work is mainly a database.

Metadata:

-Information about information?
-It's all one can say about any 'information object'.
-3 features of all information objects:
Content: what the object contains, what's it all about; intrinsic to the object.
Context: who, what, why, where, how aspects of the object's creation; extrinsic
Structure: the formal set of assumptions among individual info object & can be intrinsic or extrinsic.
-Information on types, functions, attributes and characteristics.

Dublin Core Data Model:

-Despite reading several times, did not understand this article.
-Believe it's a huge 'database' to be set up internationally to provide access to information.

Computer Hardware, Moore's Law & the Computer Museum

Computer Hardware

-Gives a lot of useful definitions, some I knew, others not.
-Increases my knowledge of computers, and their components

Moore's Law:

Amazing growth of technology. I have an Osborne computer somewhere. Looking at it and the PC I work on, the difference is more than night and day. So what happens when the limit is reached? Maybe, by then we will communicate via microchips in our wrists.

Computer Museum

I thought there was one in DC but of course it makes sense there is more than one. There is a lot of information and exhibits to see. I will consider dropping by when in CA.

Discussion - Digitization

I believe digitization is worth it. It preserves articles (scrolls, manuscripts, and rare books) for the future and provides access, usually 24/7 to anyone who has a computer. that said, I know that libraries are on a budget, budgets in several communities have recently decreased . Perhaps a partnership with private companies would be useful. A tax break or credit may be an incentive for large companies to come forth and fund digitization projects. This would entail political activity to lobby for this. It is a problem that is faced by all levels of our society. Dwindling monetary resources have to be allocated, which projects to fund then becomes the issue.

As to the comment that the world view will be dominated by the US view, I think this has been said of just about every aspect of American life, sports, the movie industry, fashion, values, food, etc. If no editorializing occurs, this is not a problem. We don't comment on the worth or value of the contents of a book. The idea is to preserve the contents and make them accessible to everyone.

-It's free, had a lot of users and many documents to support it.
-It runs on virtually all machines.
-It can be tailored to any use or application.
-I had heard about it, but didn't really know what it was.

What is Mac OS X?

-Information on Apple's operating system.
-It uses technologies from many sources to create a uniform effect.
-It's applications are well integrated.
-I found this article to be very technical, jargon was explained but it had more information that I probably would never use.

An Update on the Windows Roadmap - Supersite Blog

-The introduction of Windows Vista versus Windows 7.
-This showcases that Windows has a captive audience who have no choice but to buy the upgrades as they come out.
-There is quite a bit of back and forth discussion between participants with a lot of programming experience.

Information Literary & Information Technology LIteracy:

-It is not enough to know there are various software and hardware packages available, one must know how to use them.
-The future is now; computers are everywhere and part of our lives; I work on one all day, uploading and moving information so I shouldn't have been surprised, but it did that being connected is important.
