Week 6 Notes
Local Area Network
LAN ,WAN, and Ethernet are terms that I have used over the years to describe different cords that hook my computer up to one device or another. Now learning the actual definitions, I see why. I found it helpful in this article to click on some of the links for further explanation.
Computer Network
This article presented me with a lot of questions: My boys and I are connected with Ethernet cables to the same router and the router is connected to the Internet by Cable. We are able to use the same roadrunner account etc., but cannot access each others documents, etc. (at least to my knowledge) is our connection considered a LAN? Is the Bb Academic Suite a Hub? Are we involved in a GAN if satellite Internet access is used?
YouTube Video This video was helpful to firm up a couple of the ideas I had read in the previous article. It answered one unasked question when making the wireless router comment. I watched a few of the additional YouTube videos presented on the same page and they were interesting and helpful also.
Management of RFID in libraries. Journal of Academic Librarianship
My son's Scientific America Magazine just had an article about the use of RFID in Libraries and their communities. It theorized that eventually we will have one key fob or whatever with a RFID installed that would act as a library card, bus pass, school ID, etc. This article addressed the cost of the system to the Library. My question was the cost to the consumer! In 2006 I lost my car key that has an RFID chip in it. When I went to the shop to see about getting it replaced, it was going to coast over $250.00. Needless to say we just used the spare key until the other showed up. What will it cost to replace a lost library card? How many library cards have I lost in my life? Only two over 41 years. It cost me a total of $14.00 to replace these cards. I'm afraid that if RFID cards were introduced and my card was lost I simply could not afford to use the library.

Week 5 Muddiest Point
When using Modzilla Firefox browser I opened a photo sent to me via e-mail and instead of the picture appearing, a page full of symbols appeared. I shut down Firefox and opened Internet Explorer. I then opened the e-mailed photo and the picture appeared as intended. Is this due to the decoding that the two different browsers use?

Week 5 notes
Data Compression (Wikipedia) & DVD-HQ: Data Compression basics: Lossless and Lossy gave a very clear explanation of data compression. I have used a sip drive before, but never understood how it worked. I really thought that the DVD-HQ article gave a great lesson on coding. I enjoyed trying to decipher their examples. I also came to the conclusion that the phone system my family had several years ago must have used Lossy data compression. The phone system worked, but I had to work to understand my Dad clearly, it didn't matter where he was calling from. It wasn't the volume, I could understand the individual words, but there was still a problem and I couldn't put my finger on it. Now I think that the Lossy data compression and decompression process lost certain frequencies, pitches, or sounds that it deemed not perceptible to the human ear, but were the parts that made my father's speech flow together. I thought that these two articles were perfect for the MLIS student who doesn't have a strong science background.
Imaging Pittsburgh pulled together a lot of the ideas that we have been talking about in class. It was good to see the jargon Metadata used in the real world. It really helped solidify it's meaning. It was also interesting to see the different groups working together, for both common and individual informational goals.
YouTube and libraries is an example of someone stating the obvious that no one else has noticed yet. Does that make sense? What a great idea. Speak to people where they're used to paying attention. My son's language arts class read Caldecott award books several years ago, made video presentations and then awarded the "Best of the Caldecott" trophies. This would be something fun that a teen group could produce on YouTube. Lots of ideas can branch off from here. I've emailed this article to my churches publicity person.

Week 4 Muddiest Point
I checked in several times on Wednesday and Thursday to try to view Dr. He's lecture. It was still not available. I will not be able to view it now until Monday due to family obligations. At that time I will post a new muddiest point...yeah! I was able to view the lecture! New Muddiest Point: With all of this metadata, Dublin Core data, and just regular data, who is going to be entering all of this information into the computers? Is the profession of Librarian going to turn into the job of data entry?

Week 4 Notes
Database
A database is an organized set of information and a Database Management System is software used to organize the storage of the data.
The different database models are the Hierarchy, Network, and Relational. I likes the differentiation of the Hierarchy and Network: One parent vs. several. I think that the Hierarchy would be easier to understand, but the network would give more options. The relational model appeals to the mathematician in me. It's good that many programs work with more than one model.
Setting the Stage
The computer specific jargon is getting thick here. Meta data is the data of the data or to a librarian "catalogue data". I've heard this before somewhere: The answer to the answer, the problem of the problem? Meta data is the aggregate of information. I like the visual definition you get with aggregate...
Through meta data Information's object reflect content, context, and structure.
Librarian use Meta data to in organizing the organized information.
Dublin Core
My attempts to access this article were unsuccessful. So, I Googled "Dublin Core Data Model and came across several very good articles. The one I found most relevant was the article found at
http://www.anu.edu.au/people/Roger.Clarke/II/DublinCore.html
"The Dublin Core is a set of 'core' data-elements that were first discussed in a meeting in Dublin (Ohio, not Ireland). The Dublin Core is relatively simple; in fact it is extremely simple. This is being touted as a great advantage. " The elements (15 of them) that the meta data would be based on are include the following:

- source
- language
- relation
- coverage, and

Muddiest Point Week 3
My Questions have to do with how an operating system works within a computer: Can one computer have more than one operating system? From the lecture I learned that computers with different OS can share information via a browser, but can computers with different operating systems be networked?

Assignment 2
For my Digitization and Flickr project I loaded the pictures from my digital camera to the Kodak Easy Share software on my computer. Here I edited the photos. To upload my photos onto my flickr account I browsed my Adobe thumbnails to find the picture I wanted and then uploaded the file. The description where the account thumnail are shown also describes this process. http://www.flickr.com/photos/30316297@N04/?donelayout=1

Week 2 Muddiest Point
Okay. I just need to clarify. On the hard drive of a computer there are cylinders of information composed of spinning plates that are magnetic and 2-sided. On these plates are concentric circles of information called tracks which are broken up into sectors. The Address of the information is made up of the following: platter, track, sector. Because of this the access is random. Here's the question: On a CD is the information random access? The information is stored on a single track and even though it's broken up into sections, does the laser have to run through all of the sections until it finds the right one, making it sequential, or does it use an address, making it random?
Week 3 Notes
Intro to Linux
I have never heard of the Linux operating system, although I have certainly benefited by it. After reading this article I see we have Bell Labs and Mr. Linus to thank for much of modern computer technology. Having seen the pictures of the house-sized computers last week at the on-line computer museum, I could understand how the software for these monsters was very individualized. Building UNIX around a kernel revolutionized the business by allowing computers to share. This possibly was the start of information sharing in the digital world.
Mac OS X
This operating system developed, marketed, and sold by Apple, I am familiar with. I remember using my first Apple Computer as a teacher. Compared to having to start every thing with DOS on an IBM Computer, the Apple was amazing. I think that Apple was lucky that Steve Jobs came back.
I have not used an Apple PC in the last 10 years. However, the people I know who do use them are not interested in switching to a Windows Operating System. In fact, one of my students who is an Apple advocate cracked a joke about the "control-alt-delete" that he was sure I was familiar with as a Windows user. He was correct.
Although I have not worked with an Apple PC, I have certainly worked with many Apple products. The specialization of the MAC OS X for the iPhone and the iPod touch has added to the iwhatever revolution. Dr. He talked about the inputting of information in unnatural ways like the keyboard, these touch products take us the other way.
When I think about this article in conjunction with Library and Information Science, I think about people who carry around information on their iPods. My sons carry around music created in Ireland and Finland and delivered to their iPods via the Internet. I carry around books on tape via the same device and the same network. The possibilities are endless.
Update on windows
Okay, I'm a Windows user who has not been happy with Windows Vista. Why? After reading all of the benefits listed in this article, I suppose I should just be patient and learn the new system. That being said, time is money, and in my house time is clean clothes and a nice dinner. I've spent hours learning how to use Microsoft Office Word 2007. Is it a nice program, sure. But after nearly a year, there are still things that I could do on Microsoft's now defunct Picture it Publishing that I have yet to figure out on anything that I have that will run on Vista. Why don't I downgrade back to XP? The Excel program that the volunteer organization I work with runs on Vista, so the answer is compatibility. What is truly nice is a system that you already know and own. I truly have felt bullied by Microsoft to "Upgrade" when in many ways it has not been in my best interest.
How is this relevant to Libraries and archives around the world? Money. It costs money every time that a system has to upgrade. The question is, "Is it worth it?" The answer is, "It depends." This will be a question for institutions all over the world, from small public libraries to major corporations. Will the system ever be good enough that we can just let things rest for a while and concentrate our efforts elsewhere? I somehow doubt it.
