Week 3

1. Data Compression.
      Encoding information using fewer bits than the original representation would use.
  • Helps conserve hard disc space and bandwidth.
  • Lossless Data Compression uses statistical redundancy to preserve data without error.
  • Lossy Data Compression is used when some data loss is acceptable(jpeg images among other things).
2. Youtube and Libraries.
  • Youtube has many potential applications for distance learning and communicating with patrons in general.
  • Possible uses include instructional videos that would let users know where and how to locate and use the library's resources.
  • It could also be used to inform patrons of changes to the collection and newly acquired items.
  • By subscribing to the Library Channel's RSS feed, it would be easy for users to see any new updates as they are released.
  • The maximum file size that can be uploaded is 100 megabytes and the maximum video length is 10 minutes.
3. Imaging Pittsburgh
  • The article on First Monday detailed a project to allow access to images from the University of Pittsburgh, the Carnegie Museum of Art, and the Historical Society of Western Pennsylvania.
  • There should be up to 10,000 images available by the end of the project.
  • Having these images digitized and available from one website will allow greater ease of access and will simplify the task of searching through these collections.

Muddiest Point: I felt like the readings this week were pretty straight forward and I do not really have any questions about them at this point. I did notice as I reviewed my notes from last week that I had written down the term "solid state hard drive" but did not have any further definition. I suppose if I had to list one thing that I would not mind some clarification on, it would be that.
