Assignment 3 - Personal Bibliographic

Here is my cite-u-like url: http://www.citeulike.org/user/joanpeiffer

Somehow 31 articles came over on zotero, so I should have 40 articles, instead of 39.
After redoing several articles a couple of times, I did not try to delete one in case something else happened. So there is an extra article to enjoy.

Week 6 Readings

1) Local Area Network: I finally learned what LAN and WAN stands for. They have been in previous readings, and I always wondered, but now know about Local and Wide Area Networks. I also know that Ethernet has nothing to do with a clear odorless liquid; but still don't know exactly how it works. But I love having Wi-Fi at work and now in our home. I'll talk more about that later.
While at college, my husband and I went to Novell and participated in a computer study; and we even got paid for it. One could get dizzy clicking on all the blue hyperlinks on these articles, or just more confused with all the terminology.

2)Computer Network: A computer network is a group of interconnected computers. There are several Types of Networks. Those initials are easy to understand and remember. (especially after watching the YouTube video.) It was helpful for them to go in order of size: Personal, Local, Campus, Metropolitan, Wide, and Global Network. A question arises as to who pays for all this networking? When transmitted by telephone, or wireless to reach the Global sphere, how is it determined who is accessing it and who pays? Who is monitoring all those nets? How about laptops accessing Wi-Fi from wherever?

3)Common Types of Networks; YouTube: I guess anyone can star in a movie.

4)Management of RFID in Libraries: This was actually for first time I'd ever read anything about RFID. I somehow saw something on YouTube in another language so I'm guessing that this is what it was about. After reading the article about scanning a whole shelf of books so quickly, I was astonished! The security factor is something I would love to implement in our library. There are so many books that mysteriously "walk" out of the building. I can see only advantages to using a Radio Wave IDentifier on all materials at our library. a) Check out and check in would be so much faster. b) When other libraries call us and ask us to send them a book, we go to the shelves and look. If it is a row down, or up, or at the wrong end of the shelf, the scanner could catch it and c) it would save wear and tear on my knees every week checking the shelves for overdues. If equipped with this feature; d) The 'pages' (usually teenagers who put the books back on the shelves after being returned) could almost check themselves to see if the books were reshelved correctly.
How do I sign up? I would love to see this utilized in my library!


Muddiest Point: In this week's readings the Internet and the WWW were mentioned together. Are they the same thing? What is the difference between them?

Week 5 Readings

Data Compression- wikipdeia
Data compression or source coding is “the process of encoding information using fewer bits than an unencoded representation would use through use of specific encoding schemes.”
But Lossless, I believe means that most of the original picture, music, or whatever data is being compressed, will be seen, heard, or whatever upon decompression. Files should be original upon viewing.

Lossy may lose some data to achieve a higher compression. A digital camera is an example of lossy. When you compress and send, you may lose some data, (picture border), to obtain the best picture.


Data Compression Basics:
The author said, "this article isn't going to be too technical". His idea of technical and mine are Not all all similar. His concluding remarks summarize the article into terms even I could understand though. He states that Lossless is compressed into "exactly" the same as the original, and Lossy is "not guaranteed to be exactly" the same as the original.
He talks about LZ algorithms and how they can compress with a ratio to about 3:1. They can do this by reducing redundancy.


Imaging Pittsburgh: What a neat concept! I love how you could click on a neighborhood and the pictures taken there would show up. You can see the progression of the city and how things have changed. The fact that the University of Pittsburgh from the beginning wanted to make sure that everyone could access the information was admirable. Several people collaborated to achieve the 7,000-10,000 photo exhibit. Mr. Galloway said they had their problems, but they were able to work them out and have a common dialogue between the groups who submitted their subjects.

The YouTube article was very informative. I didn’t know that, “YouTube is the most popular internet television or video distribution site on the Internet and currently ranks number 16 on Alexa for most visited websites.” We have been on YouTube more recently since we finally went wireless. It is so fast to load almost anything you want for your viewing pleasure. The idea of having a ‘library tour’ of your services and facility online somewhere to be available for anyone to see is fantastic. I’d like to do that for our library. Much information can be made available such as instructional videos, or tutorials, for those visual learners. Or you could film part of a story time with the children for other parents to see what they are missing.


Muddiest Point: The LZ algorithms in the second article completely overwhelmed me. The talk about the different color pixels and everything mentioned went right over my head. what do we need to know about all that???

Flickr Assignment
My oldest daughter just graduated from High School in June.
I used her for my picture subject.
Tried a long time to get the photos regular size and thumbnail.

They are all on the same page (today). Thumbnail, then regular size.

Week 4 Readings

1) Database. http://en.wikipedia.org/wiki/Database
There was so much information contained in this first reading, I hardly know where to start.
But now I know that, "A Computer Database is a structured collection of records or data that is stored in a computer system."
When they were talking about the earlier data being punch cards and magnetic tape, I remember having punch cards walking around the high school cafeteria to get registered for my classes.

Then in the 90's there was much progress made with the help of Open Source, which I took to be like Open Access we've already talked about, and My SQL which could handle more complex databases.

With the Hierarchal, Network and Relational models, I thought I was in a soap opera with all the parents, and marriages, and children and relationships going on between them all.
The ACID rules actually made sense to me, which was a relief.


2) Anne J. Gilliland. Introduction to Metadata, pathways to Digital Information: 1: Setting the Stage
http://www.getty.edu/research/conducting_research/standards/intrometadata/setting.html

Data about data. Or, "Perhaps a more useful "big picture" way of thinking about metadata is as "the sum total of what one can say about any information object1 at any level of aggregation."
I have to admit to being curious about the virtual museums, and digitized libraries she was writing about. With all this Metadata and the accessibility to virtual collections, we should be able to stay in our homes and go to our 'holographic' room and visit anyplace, or any collection we want.


3) Eric J. Miller. An Overview of the Dublin Core Data Model
http://dublincore.org/1999/06/06-overview/

I have to admit that this whole dublin core was like reading another language. I totally did not get it. But under Compound Values he talks about the "weather". "These characteristics are independent of (weather) this person is the 'creator', 'publisher' or 'subject' associated with some other resource.
So in conclusion, the DCMI is like a large card catalog. We can be listed under many different headings, subjects, and titles and still all be connected and found by those looking for us.


Muddiest Point:
What is the difference between Embedded Operating systems, and LINUX, Windows, and
UNIX Operating systems?? Aren't they used for the same thing?



Responses to Week 4 readings
I responded to Author: Tamoul Quakhaan's question today about no scores being recorded. Also responded to her blog at:http://tee-quakhaan.blogspot.com/; http://melhohman.blogspot.com/; and http://emc2-technologychat.blogspot.com

Week 3 Readings

"Introduction to Linux: A Hands on Guide".
Well, if it's all the same to you, I will stay with Microsoft.

It was a good thing that Linus Torvalds wrote to someone and decided that he could make Unix better. I've never heard of Linux, or Linus, and the only reference to Unix I've heard of was in the movie "Jurassic Park".

How does Linux stay in business and get their software out there to people if it's free?
"Paid employees and volunteers alike are working diligently so that Linux can maintain a position in the market." There are employees working for Linux. Where does their paycheck come from?

If it's been around for almost 40 years, then it has to be a good product. Mr. Garrels kept on saying that it is a very secure and stable system, with "short, de-bug times".
If you like that sort of thing, it would be good for people who like to play with their toys. Anyone with this system can go and try to fix parts, and change things. You'd think that it would have deteriorated, but then he says that sometimes when problems are found, within a couple of hours, they have been solved. "Now users can influence their systems and share their remarks with the community, so the system gets better and better every day. "

Any knowledge, like programming in C, so all computers can communicate with each other, is a good thing. That one step seems to have bumped the programming people in the technology field to be able to come up with bigger and better ideas.

I just like my computers to do what they are supposed to do, when they are supposed to do them. I don't believe I'd like to have to program my computer and influence how it works, because then it would surely not work.





Kernelthread: Mac_OS_X:
At least I now know that "OS" means "Operating Systems". (Please correct me if I'm wrong)
Some students in the class have a Mac, Not that there's anything wrong with that.

Whenever an article starts out with the verbiage, " some parts are fairly technical, and the implicit assumption is that you are familiar with fundamental concepts of one or more of BSD, Mach, UNIX, or operating systems in general. In many cases I have made no attempt to provide background details of the concepts referred to in the discussion. ", it makes me want to cringe.

Many of the patrons that come to a library don't have those kinds of fundamental concepts, or want to have that kind of knowledge. There are specialized employees who work in computer stores, or with computers who can be found to help patrons understand what is out there before they purchase a new computer, or decide they want to learn more about them.
I myself have no idea of what an operating system is; how it works; or how it gets me information when I ask for it. I'm just glad that it does.

The layered type scheme used to show all the layers of a computer was helpful. It helps to have a visual picture in my head while something is being discussed.
So, the kernel is the "most fundamental" layer of Mac OS X.
(I still don't know what BSD is? Can someone tell me.) (Well, Wikipedia just informed me that is stands for: Berkeley Software Distribution (BSD)

Programming is like learning another language. Programmers have my utmost sympathy. I remember how hard it was for me to learn German, and programming seems much more difficult. There are thousands of new terms: DFM, C, elf, bundle, framework, BSD?, Cocoa, and several more that would take to long to list.

In conclusion, the author likes his Mac. He states, "Still, Mac is currently the most worthy client platform in my opinion: the only operating system currently in production that, within reason, lets you have your cake and eat it too."

He rates Mac as his first choice, Linux as his second choice and Windows as his third choice.

"If you look at current Apple computers carefully, you'll see that a lot of engineering goes into making them. They are not just "pretty" and stylish (though that might be subjective) - they are functional
well designed. Some people even call them lust worthy. "

The Wikipedia explanation of Mac was much more clear, concise, and so much easier to understand, even with my limited knowledge of computer speak.



Paul Thurrott's Windows:
This article was somewhat confusing, with all the different Windows, Windows XP, Vista, Windows 7, Professional, Ultimate, Home and Starter programs to mention a few.
I had no idea that there were so many different versions of windows being used.

Technology is changing so quickly that it's no wonder there are so many versions and updates happening on an almost daily basis. "Today Windows Vista supports about 77,000 components and devices, which is more than twice as many as we supported at launch."

Interestingly it was mentioned that there were significant security advances made and less security risks with the latest version that was marketed. With all the newsclips and warnings about the different "worms", "viruses", and "bugs" that are headed our way almost everytime we watch the news, it is good that they are trying to avert those before they attack our machines.

So now that I know everything there is to know about Linux, Mac and Windows, (haha), what do I think I will buy in the future?
Whatever's on sale.


Muddiest Question? What exactly is "digitization"?
Is it just taking a picture so that it can be copied electronically?
(Well, I just saw the other digitization articles we are supposed to read. When is that due? Guess if I did my homework, I could answer my own question!)

A P.S. to my question: Does digitization last as long as microfilm and other reproducible imaging? If digitization dosen't last as long, would it hurt the original whatever- picture, artifact, or whater to keep getting "re"digitized??? just wondering.

Week 1 Readings

After about 1 1/2 hours of trying to view the whole article by Jason Vaughn, and finally getting to it, thanks to another student's help, I thought I'd talk about it first.

I enjoyed reading this article, mostly because I understood most of it. I work in a public library and we enjoy some of the same problems.
We will be buying more laptops next month. I've wanted to implement something like a laptop check out for about two years. We only have 6 computers for our patrons to use at this time. They are busy all day long. Some days we get as many as 80 - 100 people using our computers daily. I will definitely mention this again.
Our library has wireless capabilities. We built a new building and opened February 2006. This is good because like was mentioned, the price of laptops are coming down and people are buying more and they are using our beautiful building to get connected.
There is a test library in our System which automatically shuts down the computers after 30 minutes. If UNLV wanted to do something like that and have a community area, they wouldn't have to worry about users being on their computers all day long.

Part of it was boring when he was talking about the offices not being next to each other. TMI.
But overall, it was interesting to hear that large academic libraries work the same as smaller local libraries and we have the same needs, system failures, updates, wants, and money problems!



"Information Literacy and Information Technology Literacy: New Components in the Curriculum for a Digital Culture":

If I am understanding My Lynch correctly, he wants us all to be Renaissance men and woman, understanding all things, being able to perform all things, and have skills in all area of development.

Of course, I fit into the beginning of the Information Literacy, because sometimes I can type, and do some spreadsheets, and have some basic computer skills. I can find my way to courseweb, print off the syllabus and get to my blog to respond to these articles! (My blog could also use some assistance to help it look better).

His views on the Information Technology being most important are valid. If you could only have a few employees working for you, you would probably want the most well-rounded and skilled person you could have, instead of a few specialized people. I just don't think that there are many of those type of people around.

He wrote this article in 1998. The statement he used, "a recognition of the fluid
nature of many digital forms, plus an understanding of the computer’s growing ability to edit or even fabricate what have traditionally been viewed as factual records of events (such as images).", made me think what computers have done for the Movie Industry regarding the use of special effects. There are so many computer animated and/or generated graphics out there now, it really astounds me what computers have been able to do.

In conclusion, I don't think I will grow up to be a Renaissance women. There may be hope for me to improve my skills and learn some more about Information Technology.



OCLC report: Information Format Trends: Content, Not Containers(2004):
One statement that was made in this article, "Libraries need to find ways to deliver quality content to mobile devices." is one of the reasons that I am in this program.

Don't get me wrong. I Love My Books! I like to hold them and look at the cover. I like to take them in the car with me and read them wherever I am. The patrons who visit us also like their books, CD's, magazines, books on tape and books on CD. But there a lot of people who have never been to a library, and aren't familiar with the services that are provided.

According to this report, those services need to be updated and changed for the "new generation" of technology.

I did not agree with the statement that blogs are "more honest". Who is there to check and make sure that what is written is what is right?
I also felt terrible while reading that "Fleshmet" will become more prevelent and that 70% will get together with "eworld" people instead of "real" people. That is what is wrong with society now. There are too many children and people left alone who spend all day in front of a television or computer. There should be more interaction with talking, playing and speaking to others.

My husband just took the texting ability off my, his, and our daughter's phones. He said, "if someone wants to call and talk they can, and I will answer if I want. I will not pay for someone to text us something."

So, there is change everywhere and hopefully for libraries, they will be able to discover ways to keep up with the give me everything, wherever I am concept that is being heard now.

Muddiest Point


Sorry, I don't know why it's underlining now.
The muddiest point was knowing what was due, when.
Trying to watch the lecture and get clear, concise dates was very confusing.

Blog Responses - Week 1 - 3

Week 1
I responded to Andrea Black's blog, http://alb206.blogspot.com/
and Eileen's: http://tophatsandflappers.blogspot.com/

Week 2
I responded to Jeremy Muldoon's blog: http://pittmlis.blogspot.com/
Alesha's blog: and Susasn Geiss: http://susangeiss.blogspot.com/

Week 3
I responded to Melissa's blog: http://suburbanbarnyard.blogspot.com/
and Sandra's blog: http://sandasilaghi.blogspot.com/and Brandon's http://analogfailure.blogspot.com/
I also put a response in the Disc. Board on digitization.
Okay,

Week 2's assigned readings:
Computer Hardware:
There were several terms in that article that I didn't know, so it was good to learn some new terminology. RAM, ROM, BIOS and I even learned what DVD stands for: Digital Versatile Disc.
There was still some terminology that wasn't explained: LAN, and WLAN.
Hopefully I will learn what they stand for during the course of this class.

Moore's Law:
This article was slightly confusing with all the specifics of the computer and much talk about transistors and costs and nanocomputers. But there was something in there about IBM researchers developing new methods to achieve even smaller circuits which are expected to be substantially more expensive.
I can remember being in computer rooms where the computer took up the whole room, and they cost thousands of dollars. The current size of the computers we us at work and at home seem just the right size to me and thankfully they don't cost so much that they are unaffordable to the middle class.
It would be unfortunate if research develops in such a way to have very small, but more expensive computers.


Computer History Museum:
The next time I am in Mountain View, CA, I would like to visit this museum.
It was interesting to note the Old Internet Maps they were showing from the 70's and 80's, especially after seeing your lecture and the very first picture was a map of the internet. It is now so large that you can no longer see any individual connection points, like on the first ARPANET maps.
