Week 7 - notes

How Internet Infrastructure Works

This was a nice overview of different components of the internet. I knew some of the things, but only in the sense that I knew they existed. This gave a lot of information, and I think it did a good job or presenting it simply.


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

This was pretty interesting. I never realized quite how many problems arose from the ILS. It seems to be something that just about every company has to deal with in some way (i.e. companies deciding whether or not to upgrade their technology, dealing with vendors, making sure different technologies are compatible, etc). I liked that Sirsi and Millennium were both mentioned - I've used both of these systems, so this helped me know the "characters" in this. I hadn't realized competition was an issue for ILS, either - somehow I'd just kind of assumed that the ILS stuff was always there, and hadn't realized what actually goes into aquiring an ILS and dealing with a vendor for it.


Sergey Brin and Larry Page on Google

I enjoyed this video quite a bit. These guys seem to really enjoy what they do, and it's nice that they do their best to create a work environment where their employees can enjoy what they do as well. I also think it's neat that they let their employees work on their own ideas and just see what they come up with.

Assignment 4 - Working With Jing

For my screencaptures, I decided to show the basics of playing Minesweeper.

Here's the video (unfortunately, I don't have a microphone, so it's not very interesting):

Week 6 - the muddiest point

I have no muddiest point for the lecture. However, I do have one in regards to the Jing assignment. I keep having trouble when I try to install it: it won't install all the way because I don't have Microsoft .net Framework 3.0, but the installation for that never finishes because a required service application it needs, "Background Intelligent Transfer System (BITS)," is disabled. A screencap of the error message that I get is at http://www.flickr.com/photos/42525296@N08/3991837132/.

Any advice for what I should do about this would be greatly appreciated.

My three main category titles are "parrots," "snakes," and "pandemic." My tags to show where I got the article from are "zoterogs" and "citeulike."

Week 6 - notes

Local Area Network

I knew basically what a LAN was (we had one set up in our house), but I didn't know any of the history of it. It's been around a lot longer than I realized.

Computer Network

Again, I knew what a computer network basically was, but I didn't know much beyond that. I certainly didn't realize how many different types of networks there are, or all the hardware that goes into it.

Common Types of Computer Networks

This seemed to basically just recap what the Wiki article said.

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

This article was pretty interesting. I'm not sure what I think of the RFID technology. While it sounds promising, I don't think it would be quite as good as it sounds. For instance, it gives the promise of an instant check-out or check-in time, but in many cases, the act of scanning the bar code is not what takes the most time. Rather, librarians must also open up cases, such as for CDs or DVDs, and make sure the item is still in them (an I doubt this will change, because I doubt people will stop leaving these in their players). So, at this point, I don't really see an advantage to switching over to RFID technologies.

Week 5 - muddiest point

I'm curious as to why image coding uses red, green, and blue, rather than the traditional primary colors red, blue, and yellow.
