Data Compression
I dug it, I always wondered how compression worked when you do something like zip a word document, and know I know...sort of. Although I have to admit I had some trouble with the word "lossy", it just doesn't seem proper.
Data Compression Basics
This was good because many of the acronyms that I didn't understand in the wikipedia article were covered in greater detail here. It also did a better job of explaining compression, I almost think that this article could have replaced the wikipedia article.
Imaging Pittsburgh
It was really neat to have such a relevant article. It is very neat to see all the issues that need to be addressed when developing a digital collection like this. Ohio Historic Society has several online photo databases and know I know a little better how much work went into the development of those databases.
YouTube and the Library
This seemed a bit like a YouTube advertisement. Though I definately see the benefit of this type of mass advertising for reaching a wide audience. One issue I see, though is, how do you get people to your video? There are so many videos on YouTube, it is difficult to ensure that people are actually getting to it.

I also found the data compression article interesting, but admit I'm still a little fuzzy on the details. I agree that it is neat to have a relevant article like the "Imaging" one. It helps put things into perspective, am I right? You feel me on that?
In regards to accessing YouTube videos, I suppose libraries could include the links to their videos in all of their written brochures--or if it's a university library, they could send out a mass e-mail to the whole school. I would be most worried about weirdos leaving inappropriate comments and video responses on the library video (I'm sure you can block those sorts of things, but that comment space could otherwise be an interesting forum for Q&A and discussion).
I see links to YouTube being included from the library website - a demo on using Zoom posted somewhere on the "Find Articles" page of the Pitt library site, for example.
As for comments, there is probably a way to put them through an approval process or shut them down completely.
I agree with you on the data compression articles that the second one did a great job at clearing up what the first one left out. I have used a zip drive before and wondered how it worked. My son also said that all of the music loaded onto an ipod is compressed data and can only be decompressed by an apple product (or with a conversion program) I had always known that ipods were not compatible with other MP3 players, but did not know why. Now I do.
yes, justin, the terminology seems so nontechnical. "lossy" seems a bit reductive but in a frilly sense?! as for youtube, i see the benifits for libraries to use the forum but why not just create an in-house film and post-it on the library/institutional webpages. if the purpose of the film is to be instructional. if it is for marketing purposes then sorting through youtube to find library info isn't what i think most people are looking for....now, if they want a humourous video about "shoes" then youtube is the palce to go.
