reading notes week3

1) Machtelt Garrels. “Introduction to Linux: A Hands on Guide”
(only need to read section 1, but you are welcome to read the whole document)
http://tldp.org/LDP/intro-linux/html/

To tell the truth, I do not touch Linux before, reading chapter 1 helps me get the whole overview of this operationg system. I think I need practical trainning to look what the real linux is through my eyes.

2. Max Os X
I have never deal with a Mac OS X machine before, it is the first time that I use Mac machines in Hillman library. It sounds great. However, frankly speaking, I am not accustomed to this operation system. Mac OS X and windows has many differences. Except the theory of system, interfaces are different. Perhaps, it is the reason of custom. Mac indeed have merits, the interfaces are beautiful and concise. To write more comments, I need more learning about the structure of Max and more practical training it.

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

This maybe the most familiar part to me, since I only use windows operating system in China. And windows is more pupolar in my coutry since many software only run in windows. Now my laptop runs Windows Vista home basic, I do not feel any difference compared with Windows XP except many authoried windows asking me whether to run or not. I am looking forward to Windows 7.

the muddist point in PPT(LIS 2600 week2-computer hardware)

PPT page 10 displays the class goal that" Differentiate between storage devices and storage media". However, after class I still can not differentiate them. I think they refer to the same things at some degree. In the class, the instructor did not mention them according to my memory. What is the difference between "devices" and "media"? I am a little confused.

Reading notes: Discovering computers Chapter1

This book is useful for computers beginners. Because it has lots of tables, illustrations and every chapter includes a summary. The first chapter talks about five main components of a computer, that is input devices, output devices, a system unit, storage media and communication devices. And the book also contains social issues about computers like the history of computers and impact on people's life. I feel that the content of this book is complementary to what we learned in class.

reading notes on Unit 2: Computer Hardware (9/8)

Required Readings:

1) Computer Hardware: http://en.wikipedia.org/wiki/Computer_hardware
2) Moore’s Law: http://en.wikipedia.org/wiki/Moore's_law
also the video http://www.sciam.com/article.cfm?id=what-is-moores-law
3) Computer History Museum. http://www.computerhistory.org/

I got to know multiple physical components of computer software and wiki give us concise definitions of each typical pc hardware. Frankly speaking, I am a little surprised that we use Wiki to read about the basic computer knowledge as a future librarian. However, wiki is indeed a powerful tool for definitions, though I believe we could find many materials better than wiki's definitions.

Moore's Law says that" transistor density in integrated circuits doubles about every two years". Wiki talks many aspects about this law, I am a little confused about other formulations and similar laws, especially per unit cost, why some cost increase and some decrease? In a word. the explanation of Moore's law on wiki is very comprehensive. To know every details about the law, I need to go over it several times.

I feel that the website of ”Computer History Museum" is a precious resource for us to learn every aspects of computer. And Moore's law is also embraced by the website. The picture about changing transistors on microprocessor is a good example to demonstrate the law. This is great to me to understand the law. I saw some videos on youtube played by computer history museum, which is wonderful for us the learn the history of computers. And I will often log on the website from now on.

reading notes on LIS 2600 week1

1, Title: OCLC report: Information Format Trends: Content, Not Containers (2004).
Notes: After reading the essay, I still can not differentiate the content and container in information. I think blogs and new media are containers of information. What do "micro content" and "multimedia content" mean? The adjective before content is still talking about new containers. As far as I am concerned, people and librarians pay more attention to containers, specially the newly form, such as blogs, emails, wiki. On one hand, patrons are more interested in new skills. On the other hand, librarians focus more on display organized information through various technology forms these years. I think the whole librarianship are emphasizing information containers now. How dose content work out? I am a litter confusing.

2) Clifford Lynch, “Information Literacy and Information Technology Literacy: New Components in the Curriculum for a Digital Culture”
Notes: The definition of information technology literacy is new to me. I heard more about information literacy in the past. This essay is usefull. I knew the brief meanings about these two definitions and their differences. We need to be skilled in both sides as a professional librarian.

3) Vaughan, J. (2005). Lied Library @ four years: technology never stands still.
Notes: This essay is good example for me to get the whole knowledge of changing technology in academic libraries. The author explains every aspects in details and analyzes their methods of solving various problems. I am a bit confused about the phrase of "feeding the beast". I do not know the meanings that the author use this words here. And I saw this phrase in "Double Fold" ,too.

the muddist point in PPT(LIS 2600 week1-introduction)

1, We are told that be "true" is some common characters of information. How to define the meaning of "true"? what dose "false information" mean? For example, the gas price is the last past three months were 2.95$...(the fact), if I said the wrong account, then my words include false information. Can we define what I said is not information? However, in my opinion, though my words are not the fact, they are also information.

2, Page 31 in PPT. "IT provides materials, user groups, author groups". Dose that mean the computer users or online users?

3, Page 32 in PPT. "some view IT as a threat to library recently, since less funding are available to libraries now" why less funding because of IT? Is it because more users are likely to use Internet? What about the funding before IT?
