mBsLOG

Welcome to my weblog. It is an unconventional blog in that I am not planning to post daily or weekly, but only as topics of interest emerge. I enjoyed playing a little with my initials and the word blog and am amused by the fact that it is as much something I am slogging through as something I am blogging about. This listing only shows the five most recent posts.

I will try to discipline myself to keep a more or less regular set of reflections coming, but I can't promise. I have disabled commenting and discussion as it ended up being more maintainence and cleanup than I cared to deal with. That doesn't mean your comments and thoughts aren't welcome. Should you wish to comment on what I have said, I will be happy to add your comments verbatim so long as they are not spam. Simply send an email to me at Pitt -- see my home page. I will insert it in the appropriate post with attribution if you wish. Please reference the title and date of the post on which you are commenting. Also, if you want to suggest a topic that might be covered or discussed, let me know and I will try to include it.

Here is access my mBsLOG as an rss feed.

Educating for the Future (July 30, 2008)

I received a note recently from a 1991 graduate of our program. Michal was a great student, and wrote a great article on anticipatory standards while he was here. He has worked in corporate positions, in a startup, as a consultant, and most recently as a government contractor. His note made reference to the things he recalled from his education that seemed bogus now, and things that seemed to look forward. In part he wrote: "I can recall creating a DOS-based hypertext program for your document processing class and on demonstrating it seeing some of your students understand for the first time what hyperlinking really meant. Now’s hypertext surrounds us!"

I also recollect those early years with DOS machines and all the fun we had with wrting programs to: control the color registers for the monitors, directly manipulate the ports, edit the FAT tables and so many other things. Given the work at Xerox PARC, and other places, on hypertext, it was only reasonable for us to look at the technology. In the mid eighties, Xerox gave me several 8100's with both the office and development software to build our own systems. Notecards was a sophisticated hypertext system and a thing of beauty to work with. The knowledge provided by Xerox about what was possible coupled with the accessibility of the DOS machine made it easy to build a simpler but nonetheless functional series of hypertext systems.

Michal's note makes me wonder whether I will get another note two decades from now reflecting on something we are doing today. I would like to think the work we are doing on the social periphery in collaboration systems, or ontology development, or aggregate annotations will have some impact. At the same time, I am at a point in my career where I grow fearful that I am losing touch with the direction and shape of the technology trajectory. There is so much happening and I find it hard to see the themes and the directions. Sometimes, as I think is the case for most old curmudgeons, it appears that we are breaking no new ground, but simply revisiting, out of ignorance, what we learned many years ago.

In responding to Michal's observations, I tried my best to think about what we should be teaching today to educate our students for the coming years. In part my response said "I have taken a good portion of this summer to work on some ideas about where we are going. Two things keep banging me on the head, and I have been trying to think about what they mean.

About four years ago, I started to digitize all of my personal analog history. This past year completed the digitization of every video, slide, negative, audio tape I had collected. My long dead father now speaks of his childhood on a CD. All of the video tape of my children dating back to 1986 is now on a DVD. The 30 minute super 8mm movie I made in 1968 is now also a DVD! My sons, one of whom just graduated college and one of whom will turn a junior, will each inherit about a terabyte of digital data which will be my best effort to record their lives as well as my meager accomplishments. So, knock on the head number one is how does the world change if we can develop a stable, mine-able, complete, coherent digital life history. This will probably be possible, if not common place, for my children's children. It is the basis of Gordon Bell's Life Bits project. The opportunities and challenges of these kind of repositories are many and varied -- and perfect for exploratory projects. Maybe the next hypertext project should be organization and use of life repositories.
The second knock in the head has been some work on "aggregate annotation information" or at least that was the title of the last doctoral seminar I did on the topic. Here's the skinny. Google is the best search engine because it uses Page Rank -- named after Larry Page. Page said the most important pages will be those pointed to my the most pages that are important pages. This algorithm is quite rich and more complicated than this description, but it describes the essence of the theory. One of my doctoral students -- now graduated -- used the social bookmarking system delicious to do some searching. Using bookmarked pages from delicious, he got search results that were slightly better than Google. They weren't significantly better statistically, but the key really is that they were not significantly worse -- which I would argue they should have been. What is amazing is that by "reducing" the web to only those pages that were bookmarked, we eliminated 99.9% of the pages. Delicious has only one page for every 1000 in Google. Thus with a server farm 1/1000 the size of Google we were able to produce results as good as Google's. Why? Because we don't bookmark junk! Now all we need to do is collect the bookmarks of all the smart people in the world, and we will have a great filter -- aggregate annotation information.

This summer, I spent an inordinate amount of time writing programs that analyzed RSS feeds I like to read. As a result, I now have a prototype feed reader that analyzes what I read, statistically clusters it, breaks out important words and topics, makes them into weighted anchors that "attract" incoming news articles and visualizes my information space to let me know if I want to think about something. Statistical inferences, aggregate annotations, and visualization of ad hoc information stores in real time all seem to offer endless vistas for development.
