In my tech reading I found a description of a brief video that both entertains and describes what XML is and why the Web 2.0 is important. Titled Web 2.0 ... The Machine is Us/ing Us this video by Michael Wesch, a cultural anthropologist from Kansas State University, is five minutes worth spending.

One thing I found ironic. I read about this video while reading David Margulius' column in the second to last print issue of InfoWorld, a tech magazine that I have been reading and learning from for years. Next month they are relying exclusively on their internet based publishing in a way that relies on and use the  technologies Michael so cleverly describes.

In the old days of fixed font typewriters the period at the end of a sentence was always followed by two spaces. With the advent of proportional spaced fonts this convention is no longer appropriate as the system automatically adjusts to the appropriate period following spacing. (It is particularly a problem if you convert a word document into a HTML file. You end of with lots of extraneous non breaking spaces.) Nonetheless this convention is built into the DNA of long time typists and hard to change. Fortunately, there is a setting in Microsoft's Word (version 2000 and up) that tells the grammar checker to look for this error and flag it for correction.

In general select the Tools/Options/Spelling and Grammer. In the Grammer section you can make sure that the system checks for the appropriate number of spaces. The screen shot below shows this dialogue for Word 2004.

Being smart enough to know better, I have installed Vista on my main computer. First as an upgrade then, when I was unable to get IIS to run an ASP 2.0 application, as a fresh install. Things have been better with the fresh install HOWEVER I was unable to see any of the graphic images in my locally run web pages.

I searched IIS interface, read the help files locally and on line, and searched the web, all to no avail. Then I thought to look again at the various windows features (Control Panel\Programs\Programs and Features\Turn Windows features on or off) and there it was (Internet information Services\World Wide Web Services\Common Http Features\Static Content). Turning that on gave me the missing graphics!

I hope that this note helps others avoid the few hours I spent trying to solve this problem. Now on to install VS 2005.

Support groups on the web are a huge phenomena. However, what is the best way to organize the user experience. For asynchronous groups there are two common options a non-threaded time oriented bulletin board were users' entries get included in a single list and a threaded discussion form where a root entry (any number of root entries) is made that people then comment upon.

The non-threaded form seems like it would be the easiest for “mom and pop” to understand but for groups of any size it would be a difficult cognitive task to keep up with the various threads of conversations. Sort of like arranging all of the individual statements at a party into chronological order then trying to figure out how they were grouped with one another. For small groups this would be possible because I think they would be more likely to have a single conversation. You mentioned that you keep groups to around 50 participants. I would guess that many of those have a very few individuals who participate actively and that in effect they have become a small group.

The threaded discussions make sense to me and do reduce the cognitive load of keeping conversations coherent. But I have never really liked the narrow view you get of them when they are collapsed into the original post. While I have seen different ways to represent the richness of the comment space none has been particularly satisfying to my tastes. You exchange load problem of the first option with a new one, the need for the user to search for and identify which conversations of interest. The threaded interface seems like a difficult navigational hurdle for non geek users.

I have been considering merging the two approaches perhaps giving the user a moment by moment choice as to the way to look at it or by offering two views of the same data. That would be easy enough to implement but the trick would be to devise a model/approach that would make sense to mom and pop.

Jon Udell is joining Microsoft.

Why should I/we care? I started working with computers over two decades ago and at the time knew very little about them. I was a clinical psychologist and had only worked with statistical programs (using a mainframe and punch cards). No computer classes in college or graduate school. No personal computer (this was after all at the very beginning of the PC). So how did I learn? I started reading Byte Magazine (as well of lots of other stuff). Each month I would read the articles in Byte, which I often did not understand, and slowly I began to understand to terms, concepts, and approaches that under gird computers.

Jon wrote for Byte and I have been reading his articles ever since. Over the years he has taught me a great deal and has clearly and powerfully presented new ideas in a way that helped me see how they could be used to support my users. When Jon makes a recommendation I listen. For example he recently mentioned the podcasts from the Long Now Foundation, Seminars On Long-term Thinking, I started listening and have become hooked. They are terrific (more about them in some other posts).

At any rate, I have been reading and trusting Jon for years and if he is as excited as his self-interview suggests, then I am really looking forward to what he is about to do.

Congratulations Jon!

Clay Shirky's talk, Making Digital Durable: What Time Does to Categories (Audio/Discussion), is a part of the fascinating Seminars About Long-Term Thinking (SALT) hosted by Stewart Brand of the Long Now Foundation whose fame began in the 60s with the creation of the Whole Earth Catalog which Steve Jobs, the co-founder of Apple Computer, called the conceptual forerunner of the web search engine.

Shirky talked about the difficulty of preserving our information over the long term. Much of his focus was on how one could find information that had been stored. He described the difficulties of structured catalogs. Comparing them to lost languages for which we have no Rosetta stone. As a solution he suggested "degeneracy" that is classifitory redundancy so that the same thing is said in many different ways. Degeneracy is embodied in the "new" social tagging systems such as flicker, and del.icio.us. "The only group that can categorize everything is everybody" and by enabling this sort of categorization we have an ever emergent understanding of how people think about these items and can therefore find they. Perhaps more importantly, these systems also alow us to understand how our understanding changes over time.

The notions of tagging have long been used to help locate information. In searching the scientific literature these are called "key terms" which are associated, by the author or others, with a particular article. When searching for some information I would rarely choose to start with such classifications as the Dewey Decimal system. Rather I enter some key terms that would seem to me to fit the concept I want to understand and use what I find there to expand my search to gather in the web of knowledge that surrounds it. What tags adds to this information is that other readers add sharable terms which will expand and enrich that web of understanding making our information links more fruitful.

Shirky's talk is a great listen and a good jumping off point to expand your own thinking about how to find what you want and how to understand the meaning of what you find.

In the most recent version of DNN 3.3.5 and 4.3.5 clicking a file link will fail in Firefox if the file name has any spaces in it. The work around is to eliminated those spaces until a fix is provided.

Error: You do not have permissions to view the requested file

In earlier versions of DNN uploading a file would allow one to easily make it available to portal users. With the more recent version 3.3.5 (and I assume the 4.3.5 version as well) they have added an option to store files in the file system (secure and unsecured) or in the database (secure).

By default the directory with the previously uploaded files which was formerly open is now marked as secure. This breaks the accessibility that we had come to expect. While I am all for security breaking this is not a great choice.

To change the behavior back to what you expect open the file manager go the the Security Settings at the bottom of the page and allow All Users to view these files.

One important note about the file system secured files. These files are only secure when DNN accesses them. The user can enter the full URL directly into the browser and access the, evidently not so secure, files.

In its default installation DNN (up to and including 3.2.2) breaks the expected user experience with regards to links. By default the style sheet sets links text-decoration: none;. What this means is that the user has only a slight shift in color to identify a link. Moreover, unlike the browser's typical default, visited links do not look any different than unvisited links. I for one rely on being easily able to identify a link because it is underlined and whether or not I have visited it based on its color. Jakob Nielsen's Alertbox article entitled Guidelines for Visualizing Links provides great information on why this is important.

So how do you fix the problem? There are two options.

• For a single site go to the Style Sheet Editor which you will find on the Admin > Site Settings page and add "text-decoration: underline;" (without the quotes) to the a:link and a:visited styles.
• If you want to fix all of the sites change the a:link entries in the ..\Portals\_default\default.css file.
  

Making these changes helps your users better understand and use your site.

UPDATE: This code only works in Firefix and not IE (tested in version 7). After much searching, experimentation, and trial and error work I found that dropping the trailing semicolon allowed this approach to work in both browsers.

I like Joel Spolsky's take on the software world. He also is interested in good user design. In a recent review of Sprint's new Power Vision Network phone he has an hilarious (or sad if you were the designer of this disaster) review of the free phone they sent him. The quote I liked the best

13. Remove the battery and put it in again. That should get you back to the main menu.

To get the full effect and read about a really poor user experience read his full post.
