Reading Notes- Week 11 (reposted)

Reading Notes- Week 11- Im reposting the notes so my blog is somewhat in order.

1) David Hawking , Web Search Engines: Part 1 and Part 2 IEEE Computer, June 2006.

I found this article on search engines informative. I hadn’t really thought about the vast amount of space a search engine uses to be efficient. I also found it interesting that there were many different aspects of the search engine in order to make it work. For example, a politeness delay is used to prevent a crawling server from having too many requests at a time. When the article discussed duplicates, it mentioned that “sophisticated” methods were needed in some case. I wonder if these methods are not employed or just have yet to be available because of the many duplicates that can be found in a typical search. The second part of the article was more confusing to me. I didn’t completely understand how the search engine knows which documents to skip, and how it numbers different documents.

2) Shreeves, S. L., Habing, T. O., Hagedorn, K., & Young, J. A. (2005). Current developments and future trends for the OAI protocol for metadata harvesting. Library Trends, 53(4), 576-589.

This article discussed the Open Archives Initiative. This initiative works towards creating metadata standards to be used universally. The creators of the initiative had hoped that people would use the standards as well as implement others along with them. Open Language Archives Community is one such community that has extended the standards they use beyond OAI. The article discusses current developments, issues, and future developments for the OAI community. The issue of metadata formats made a lot of sense, as more formats means that there is no standard.

3) MICHAEL K. BERGMAN,  “The Deep Web: Surfacing Hidden Value”

The deep web consists of all the web pages that can not be accessed by “traditional” search engines. I was surprised by the statistic: “Eighty-five percent of Web users use search engines to find needed information.” What do the other 15 percent use to find information? I would have thought that everyone used search engines. I was also surprised that many deep websites are visited more often then some surface websites. I would think that the larger amount of traffic to the site would make it a surface site.

Reading Notes- Week 10

Apparently I did the readings for week 11 instead of week ten. Oops. On the bright side, I  wont have to do any readings next week! There are my notes for week 10 and I changed the other post to "Reading Notes- Week 11." Sorry that it's out of order.


1) Mischo, W. (July/August 2005). Digital Libraries: challenges and influential work. D-Lib Magazine. 11(7/8). http://www.dlib.org/dlib/july05/mischo/07mischo.html


This article about digital libraries was informative. The Digital Libraries Initiatives provided funding for improvement and implementation of digital library systems. I It is important to being working on technologies to benefit the library field. I wonder what further initiative projects have been created since this article was written in 2005. We continually are given readings about interoperability.  I guess this is an issue that we will continue to come across in our education and careers.

2) Paepcke, A. et al. (July/August 2005). Dewey meets Turing: librarians, computer scientists and the digital libraries initiative. D-Lib Magazine. 11(7/8). http://www.dlib.org/dlib/july05/paepcke/07paepcke.html


I was surprised to read that part of DLI was the "uniting librarians with computer scientists." I suppose it shouldn't be such a surprise to me, but it seems like librarians have been pretty in-tune with technological changes. Then again, it has been at least 5 years since DLI began. While many of the topics brought up in this article shouldn't be new to us, (for example: "While information accession now rests on a highly technical infrastructure, the core function of librarianship remains. The information must be organized, collated, and presented.") This article was an interesting read.


3) Lynch, Clifford A. "Institutional Repositories: Essential Infrastructure for Scholarship in the Digital Age" ARL, no. 226 (February 2003): 1-7. http://www.arl.org/resources/pubs/br/br226/br226ir.shtml


 This article on Institutional Repositories discusses the implementation of institutional repositories, as technology changes, introduced a different form scholarly communication. This article brought up topics we have been discussing in our other classes in this program. Lynch states that institutional repositories improve access for users, which seems to be true of almost any information on the web. I find it interesting that this article was written eight years ago, and publishers continue to control research publications, rather than institutions maintaining their own repositories for the most part.

If we have posted reading notes for every lecture, including week 10, does that mean we are no longer required to post reading notes to our blog?

Reading Notes- Week 9


1) Martin Bryan.  Introducing the Extensible Markup Language (XML) http://burks.bton.ac.uk/burks/internet/web/xmlintro.htm
I am not sure if there is something wrong with this link. There is nothing about XML on the page that the link redirects me too. For now, I will skip this article. Are others having similar problems?


EDIT: Devon and Katie both found links to this article. Apparently I'm not as good at sleuthing around for these articles as I thought. http://onlinelibrary.wiley.com/doi/10.1002/bult.104/full


I liked the layout of this article, and I wish I had read it before the others. This article was very informative about XML. I found it interesting, (as well as logical) that there probably will never be a standard coding system that is suitable for all uses.

2) Uche Ogbuji. A survey of XML standards: Part 1. January 2004. http://www.ibm.com/developerworks/xml/library/x-stand1.html
I found this article very technical and found it hard to grasp some of the information presented. XML is based on Standard Generalized Markup Language. This article discussed different aspects of XML that are standards.

3) Extending your Markup: a XML tutorial by Andre Bergholz PDF
I had trouble opening the PDF. I found the article somewhere else if anyone else was having trouble: http://pdffinder.com/get/extending-your-markup-an-xml-tutorial.pdf
After reading the daunting Ogbuji article, I felt better reading the introduction to Bergholz’s article. Bergholz states that XML allows for annotation. XML is both easier for humans and computers to read. I found this article to describe the standards in a much simpler way than the previous article. Putting the explanations of XPointer, XPath, and Xlink together made them much easier to understand as they are used for a similar function, which is linking. These supporting languages allow for a better means of linking than HTML is capable of.

I like the w3school’s tutorials because of the visual examples where you actually get to see the coding of XML as we did with HTML. This article explains XML schema. It explains that XML schema describes the different elements of the XML file. Simple elements are made up of only text, while more complex elements can have attributes. I am interested in learning more about XML. I can see this language as a valid alternative to HTML.

Reading Notes- Week 8


1) W3schools HTML Tutorial: http://www.w3schools.com/HTML/

I found this tutorial very informative, as I have very little experience with HTML. The only thing I questioned were the comments in HTML. Why would you need to insert comments, if they aren’t displayed? I’m guessing it helps when one wants to change the HTML, but I think the tutorial could have described why it is used better. I found it interesting that there is a way to view the code of websites. I am excited to see what assignment 6 is going to have us do with HTML.


This cheat sheet seems like it would be very helpful if one were already familiar with HTML. After reading the previous tutorial, this would make for a good reference sheet, so one doesn’t have to look through the long tutorial for a specific element.

3) W3 School Cascading Style Sheet Tutorial: http://www.w3schools.com/css/

At first, I was confused as to the difference between CCS and HTML. After rereading the beginning of this tutorial I started to understand the use for CCS with HTML. HTML is used to describe how a document should be laid out, while CCS adds color and different fonts to style the HTML in an easier way.

4) Goans, D., Leach, G., & Vogel, T. M. (2006). Beyond HTML: Developing and re-imagining library web guides in a content management system. Library Hi Tech, 24(1), 29-53.

CMS seems like its use is beneficial in libraries because it allows staff to add information to websites without having the knowledge of HTML. Though I think HTML is useful to know, in some instances it might be easier to use CMS. Content management systems allow for the standardization of websites through the use of templates. I found it interesting that CMS might be more difficult for librarians who are familiar with HTML. I wonder how frequently CMS is used in libraries over HTML.

Muddiest Point 10/25

It was mentioned that the 404 errors occur when trying to access a page that has been moved. I had always assumed most of these errors where from deleted pages. Do these errors ever occur because the page was deleted rather than moved?

Reading Notes- Week 7



I found this article informative and very easy to understand. I thought it was interesting that a router must make sure not to clog the networks of “innocent bystanders” as it sends information from one computer through many others to its intended destination. Backbones are also interesting in that they connect multiple networks together. I also found the section on IP addresses to be informative. The deference between servers and clients seems pretty basic to understand, but I had never heard of the term “client” in this context.

2) Andrew K. Pace (2004). Dismantling Integrated Library Systems. Library Journal, 129(2), p.34-36. Full Text

This article discusses interoperability of Integrated Library Systems and the changes in ILS. It discusses the benefits of starting over and the costs that arise from starting over. I was glad to read that some librarians are creating the technology for online use instead of using vendors, even though the article states that it creates a problem with interoperability. These technologies are being put on the Internet as open source. We keep coming across the term open source in our classes, and this article shows how it affects librarians.  


3) Sergey Brin and Larry Page: Inside the Google machine.

The beginning of this video seems to pertain the most to the first reading. I found the image of the Google searches that are made throughout the world to be interesting. I wonder what this image would look like today. Would there be many more searches in Australia today, three years after this video was created?

Comments- Week 6



Reading Notes- Week 6


Local area network-

I was familiar with the basic concept of LAN prior to reading this. I wasn’t aware that Ethernet and wifi was considered LAN, (which probably proves that I was mistaken when I said I was somewhat familiar with LAN). I was aware that LAN was a form of connection for computers and devices; I just hadn’t associated the term with wifi. I found the information in the Wikipedia article interesting. It helped me become much more familiar with local area networks.

Computer Networks-

Since we are always signing into networks, I am glad we were given this reading. While this is much more broad than local area networks, it is interesting to learn more about computer networks because of their necessity in this digital age. I found it interesting that the internet is used as part of overlaid networks. I was surprised that the hardware of computer networks were familiar to me.

Video-
Personal area network is the most common.
LAN (within one building)
Wide Area Network
Metropolitan area network- city

This video was informative about the most common networks. I was unfamiliar with Metropolitan Area Networks as a term.

Coyle, K. (2005). Management of RFID in libraries. Journal of Academic Librarianship, 31(5), 486-489.

Radio frequency identifier- I was not familiar with this before I read the article. It was interesting that RFIDs are advanced forms of barcodes that use magnetic fields to read the chips. As I was reading this, I kept imagining the little plastic strips that are sometimes found in books or other items that when you open them up, there is a metallic strip inside. Does anyone know if this is the same thing? I have always wondered what those little strips were for, but thought they were more for security rather then identification. (If they aren’t RFIDs, can anyone tell me what they are?) I think the implementation of RFIDs in libraries would be useful. The article states that the cost for RFIDs is much greater than barcodes, but I wonder how much more it costs. It would make more sense to use this technology for retail because the prices of the items could be increased (not that consumers would like to pay more for items because of their tagging devices).

Reading Notes- Week 5


This week I decided to take traditional notes on the readings rather than comment on each of the readings. I hope we are allowed to post these kinds of notes.

Database- Wikipedia
       -      Every major organization uses operational databases.
·     -       Those who don’t have access to the operational data use the data warehouse.  The data from the operational database is summarized and put into the warehouse.
·     -      Analytical databases are used to analyze the information that is in the data warehouse.
·
      IMDB is an external database. External databases are not used by a single organization.
·
      The entire web is a hypermedia database.
·
      Object database model is used to ensure that databases and programs of the same industry used the same “type system.”
·
      The most common type of storage for databases is B+ trees and ISAM.
·
      Indexing improves performance- makes queries run faster and more cheaply.
·
      Replication- keeping multiple copies of the database on different computer hard drives. –Allows for better access.
·
      Locking a database ensures that a file isn’t changed during a transfer.- there are multiple types of locks.
·
      Deadlocks- when a transaction tries to change information that has already been locked.

 I have found that databases are very complex systems and, at times, confusing to those unfamiliar with how databases work.

Anne J. Gilliland. Introduction to Metadata, pathways to Digital Information: 1: Setting the Stage
·      -     Metadata- data about data
·
      Provides information for accessing collections in libraries.
·
      Context, content and structure of data are described by metadata.
·
      Metadata describes “administration, accessioning, preservation, and use of collections.”
·
      User-created metadata
·
      More metadata is applied to something over its lifetime.

Eric J. Miller. An Overview of the Dublin Core Data Model
·      Dublin Core Metadata Initiative (DCMI) works toward making digital metadata universal throughout the world for every field.

My metadata notes are much shorter than my notes on the database article, because I felt confident in my understanding of the metadata article. My notes for The Dublin Core Data Model are short for the exact opposite reason. With all the coding, I wasn’t sure what I was supposed to be getting out of this reading. I am interested to understand these concepts, but I am currently lost on this topic. I hope there will be some clarification in class.

Muddiest Point- 9/27

I am confused about vector images. Are there no pixels in vector images, or are the pixels merely aligned in a way that the image looks clean to the human eye?

Comments for Week 4



Reading Notes- Week 4


Data Compression

Before reading about data compression, I could make a fairly decent guess as to what data compression was- making a file smaller. Lossy and lossless compression seems like it will play an important role in our future careers as we digitize documents. In our field, we will have to decide whether we are willing to lose data in our files in order to conserve space in our hard drives, or have larger files with less loss of data when the document is decompressed. As for the longer article, I wonder if we will ever come across an instance where we would need to write this kind of compression, or if the compressor will always do it for us. It is interesting to see how it works.

Edward A. Galloway, “Imaging Pittsburgh: Creating a shared gateway to digital image collections of the Pittsburgh region” First Monday 9:5 2004.

This article on the photo digitization project was interesting. Being in the archives tract, the project discussed in this article might be similar to a project that I do in the future.

Paula L. Webb, YouTube and libraries: It could be a beautiful relationship C&RL News, June 2007 Vol. 68, No. 6

The link that was provided on courseweb didn’t work for me, so I figured I would post the link that I found:

Integrating Youtube into the library system could be beneficial to libraries, but I don’t know how practical it is. The video that web discusses on “How to Find the Reference Desk” for Valdosta State University might be useful to some people, but how often would it really be used? A patron at the library wouldn’t know that they can’t find the reference desk until they are already in the library and probably aren’t sitting at a computer. Obviously, there are other instructional videos libraries could upload that would be more helpful, like a video on how to use the online journal databases. I can’t think of other videos that a library could upload, but that could be because I never associate youtube with libraries. Maybe this is a technology that libraries will start using in the near future.

Muddiest Point- 9/20

I just wanted to clarify what direct manipulation is. Does direct manipulation refer to having icons available on the desk top so a program can be accessed directly as to eliminate the need to search through the computer to find the specific program?

Reading Notes- Week 3

1) Machtelt Garrels. “Introduction to Linux: A Hands on Guide” Section 1
    (only need to read section 1, but you are welcome to read the whole document)

I found this reading does not seem like it was intended for someone who isn’t familiar with computer operating systems. If someone wanted to learn what Linux was from reading the “What is Linux” section with no previous knowledge of it, there would have to be a lot more information. In the first few paragraphs, I was already wondering what POSIX, and UNIX are.

“Modern Linux not only runs on workstations, mid- and high-end servers, but also on "gadgets" like PDA's, mobiles, a shipload of embedded applications and even on experimental wristwatches. This makes Linux the only operating system in the world covering such a wide range of hardware.” With this statement in the text, I wonder how often I have come across Linux with out even knowing it. Before reading this section in Garrels’ book, if I had been asked if I have ever used Linux I would have said that I have never used it before. According to the document, Linux is “an important player on the desk top market.” I wonder if this is still a true statement, as I haven’t come into contact with it knowingly.




If our assigned reading for Linux was too little information to help me understand Linux, then the kernelthread reading had far too much information for me to understand anything about Mac OS X. I am glad the Wikipedia article was also assigned. This is the operating system that I am the most familiar with. Learning a little more about the operating system that I utilize was beneficial.



3) Paul Thurott “An Update on the Windows Roadmap”    

This newsletter doesn’t focus on the more technical aspects of the Windows operating system like the other articles focused on. It was more easily understandable than the other articles because it was targeted toward the average user of the system. It also felt more like an advertisement by Windows because it didn’t discuss the negative aspects that windows is notorious for, like being susceptible to malware.

Week 2 Reading Notes


Computer Hardware- Wikipedia

Although I have been using computers for most of my life, I have never really thought about the hardware that makes computers work. While I have heard the terms motherboard, and RAM, I probably couldn’t have correctly defined either of these terms, and many other of the other components. It’s interesting that I am more familiar with the external pieces of a computer than the more important components like the CPU, which Wikipedia refers to as the “brain” of the computer.

Moore’s Law- Wikipedia and Christie Nicholson’s “60 Second Science” video

Moore’s Law is a trend that I have never heard of before, but it sounds logical. Early computers were so large that they took up entire rooms, but following the trend that Moore’s Law defines, today we are able to carry around iPads or even our phones as our computers that have more capabilities than the first computers. It is expected that Moore’s Law can’t continue indefinitely. Although we might not need to make our devices smaller, since the paper clip-sized phones that Nicholson suggested in the video might not seem practical, why couldn’t the size of the devices remain the same while the technology keeps doubling its storage space?

Computer History Museum

When visiting this website, I spent most of my time going through the Timeline of Computer History Exhibit. I was amazed by the size of the Complex Number Calculator completed in 1939, until I saw the Harvard Mark-1 calculator, which was completed in 1944. It’s incredible that something that large a size was needed for something most of us have as an application in our cell phones. Even if we were to carry around a separate calculator, it would easily fit in our pockets.
Another interesting fact that I came across was that the first email was sent in 1971. I thought it would have been more recently.

Muddiest Point- Week 1 (again)

Looking at the schedule of classes in the syllabus, fasttrack weekend is unclear. When will our class be meeting on fasttrack weekend?

Week 1 Reading Notes


OCLC report: Information Format Trends: Content, Not Containers (2004):
       The findings of this report make a lot of sense. Even with it being a little out dated, information found in a container is still more important to its use than the type of format in which the information is kept. The cost and convenience of using a specific container determines the frequency the format is used. About six years after the OCLC findings were reported, online resources have gotten even more accessible. With the “massive shift to electronic media” that the report predicted to continue, I wonder how close the projected numbers for the change in daily volume of content are to the actual numbers from 2009. How accurately did they predict the amount of text messages and blogs? This report shows that libraries have to evolve with technology in order to provide the most convenient containers for the content.

Clifford Lynch, “Information Literacy and Information Technology Literacy: New Components in the Curriculum for a Digital Culture”
         Clifford Lynch’s position paper discusses the necessity for education in how to work technological systems along with traditional literacy today. Even if someone has the ability to read and write, one might not be able to communicate and learn new information if they are unable to use technology. People must continue to learn to use technology throughout their lives because of the continuous changes in technology. Not only people in the field of information science need to be able to use information technology.
        
Vaughan, J. (2005). Lied Library @ four years: technology never stands still. Library Hi Tech, 23(1), 24-49.:
          This article is interesting because it shows how libraries need to constantly be updating their use of technology. Vaughan explains the changes that the Lied Library needed to make, and will continue to make, in order to stay current with the technology and provide the best environment for its patrons to use technology. Libraries need to update their current software, and implement new systems as the technology advances. Vaughn discusses the difficulties that arise with technology, which include: cost, temperature, space, and theft.

Muddiest Point- Week 1

Looking through the syllabus I noticed that it says "Assignment # is out" for each of the six assignments. Does this mean that the assignments will be due at 12 PM on the monday after it is out?

Also, should the readings have been read before the lecture that it is listed on or should they be read by the following week?
