Week 5/6 (Sept. 29-Oct. 6)
Muddiest Point:
This is an issue regarding compression and preservation of different file types which I have encountered when working with multimedia files in an archive. Is it possible for a computer to detect previous versions of a file that was saved as a different file type? For example, if you download an image as a .jpg file, import it into photoshop, alter it, and then save it as a .gif file or .tiff file, can a computer theoretically detect that the .gif file used to be a .jpg file? Such a trail is important for preservation, because the extension might obscure the fact that a file might have been compressed in a lossy format before, so at first sight it might look as if a file is compressed in a lossless format, even though it has been compressed in a lossy format before...
Reading Notes:
This week was the week of networks, both in LIS 2000 and in this class, and I am feeling a bit networked-out. Like many people, I have become acquainted with LAN networks at work while crawling under tables to disentangle some amorphous cable masses to figure out why a printer got stuck. As far as I understand it, LAN networks still depend on hard wires (co-axial cables as we learned). What is important here is that LAN networks do not depend on leased telecommunication networks, which gives the owners more control. As far as I understood, ethernet is a technology that enables LAN (the history of ethernet was actually fairly interesting, too -- I was not aware it was invented by R. Metcalfe at XEROX.) The article on the variety of computer networks was dizzying -- I was particularly interested in MAN networks -- who has control over MAN's -- cities or towns or private companies? I didn't know that the internet is short for internetwork. I want to know more about the physical infrastructure of the internet -- where are the hubs located? Important is the mix of private and public networks, which politicizes the whole issue -- who controls the access to these networks? And how are libraries connected to them? Does the U of Pittsburgh have a CAN, by the way?
RFID
this was a very informative article with a pragmatic perspective on RFID -- as a technology, it brings advantages, but also new pressures to increase efficiency (and potential job cuts) -- I also found her reflections on the rationale of libraries to introduce new technology very enlightening: a technology becomes introduced, is around, and libraries have to adapt and deal with these changes -- with RFID it sounds as if the development is going in this direction, if libraries like it or not....
