"Nurses quickly learned how to hack the system to save time. For example, if a patient's bar code didn't scan correctly on the first try, nurses often entered the seven-digit bar code number manually rather than rescanning it.

"Nurses also felt that the computer system's demands forced them to focus on pill-pushing. If meds weren't given on time, nurses had to take time out to tell the system why. Many feared this could result in poor performance evaluations.

"'I found myself walking away from important conversations with patients and families in order to fulfill the computer's demands,' said a VA nurse who spoke on condition of anonymity. 'I feel like robo-nurse, and I don't like it.'" --Bar Code Tech Drives Nurses NutsWired)

Does manually entering a bar code number really count as "hacking"? I think a system is probably broken if you have to "hack" it to make it work. Maybe the nurses were "optimizing" the system instead.

"Rightly or wrongly, record companies are detested by politicians (for corrupting youth), by webcasters (for demanding royalties), and by their customers (for inflating prices). Musicians and songwriters are famous for loathing the labels... Radio and MTV aren't in the industry's corner... And the electronics industry's attitude toward the labels is summed up by an Apple slogan: Rip. Mix. Burn. Which, a music executive once told me, translates into..." Charles C. Mann --The Year the Music DiedWired)

"Wikipedia ( http://www.wikipedia.org ), a community-built multilingual encyclopedia, is announcing that the English edition of the project has reached a milestone of 100,000 articles in development.... Wikipedia is a public WikiWikiWeb, a website where anyone can edit any article at any time. Users build upon each other's edits, and vandalized articles are quickly repaired by restoring an older version. In Wikipedia's second year, thousands of volunteer editors from around the world have added 80,000 entries to the English version and 33,000 more to the other language editions of Wikipedia. This surge in growth has made Wikipedia the world's largest and fastest growing open content encyclopedia and the largest WikiWikiWeb.'' --Wikipedia, the Free Encyclopedia, Reaches its 100,000th ArticleWikipedia.org)

Inspired by Wikipedia, in July of 2002, I launched a collaborative open-content Glossary of Interactive Fiction, which seems to have plateaued at about 180 or so terms. Anyone is free to suggest or revise an entry.

"Not so many decades ago, you couldn't buy or legitimately connect your own phone or other telecom equipment to the public telephone network in the United States.... Virtually everything related to telephone communications had to be leased from the local monopoly phone company, which also performed all installations and maintenance. Remarkably, it was even prohibited to attach shoulder rests or any other gadgets to phone handsets..." --DMCA: Ma Bell Would Be ProudWired)

Minimally Invasive Education: "This is a system of education where you assume that children know how to put two and two together on their own. So you stand aside and intervene only if you see them going in a direction that might lead into a blind alley." Sugata Mitra put a computer with a high-seed Internet access into the wall of a filthy slum. Almost instantly, slum children were using the computer to surf the Internet, paint pictures, and play music. "If computer literacy is defined as turning a computer on and off and doing the basic functions, then this method allows that kind of computer literacy to be achieved with no formal instruction. Therefore any formal instruction for that kind of education is a waste of time and money. You can use that time and money to have a teacher teach something else that children cannot learn on their own."

--India: Hole in the WallGreenstar)

The children didn't know what a "File" means, but they knew that if you clicked it, you could save and load your pictures. Some didn't even know what a "computer" is, but their creativity and curiousity more than made up for it. Another interesting quote from Mitra: "only reaction we got from adults was, 'What on earth is this for? Why is there no one here to teach us something? How are we ever going to use this?' I contend that by the time we are 16, we are taught to want teachers, taught that we cannot learn anything without teachers."

Women in Bangladesh who fold their saris filter out more of the disease-carrying organisms that cause cholera than the women who filter through unfolded cloths, or who don't filter at all. While folding saris to make eight layers filters out almost all of the harmful organisms, this method means that women gathering water had to wait seven minutes for the water to seep through the cloth.

--Fight cholera with Sarees, Says StudyTimes of India)

That's a usability issue -- the material (saris) are cheap & plentiful, but getting them to work effectively takes time. People don't like changing their habits if they don't see any immediate benefit -- not even when their lives depend on it. As it happens, folding a sari so it has four layers is still effective enough to cut cholera cases in half, and it doesn't slow down the water nearly as much.

This is great news of a low-tech, low-cost strategy for fighting disease.

On a completely different note, here is the abstract of the article in which the researchers publish their findings. "Based on results of ecological studies demonstrating that Vibrio cholerae, the etiological agent of epidemic cholera, is commensal to zooplankton, notably copepods, a simple filtration procedure was developed whereby zooplankton, most phytoplankton, and particulates >20 µm were removed from water before use. Effective deployment of this filtration procedure, from September 1999 through July 2002 in 65 villages of rural Bangladesh, of which the total population for the entire study comprised 133,000 individuals, yielded a 48% reduction in cholera (P < 0.005) compared with the control." Is this good scientific writing? Can scientists do better, especially when people's lives are at stake?

"Most writers know the value of an informative title, but many beginning web authors don't know that each web page needs two kinds of titles. The in-context (IC) title always sits at the top of a page, with the rest of the document immediately beneath it.... The out-of-context (OOC) title is frequently displayed by search engines or archive pages, as part of a long sorted list." Dennis G. Jerz --Titles for Web Pages: In-Context and Out-of-ContextLiteracy Weblog)

The document referenced above is indebted to a 1998 AlertBox column, "Microcontent," which is far too geeky for my newbie web author students who need the excellent lessons it contains.

"An act of reading electronic language involves:

1. Setting up an electronic language environment;
2. Selecting particular input into the electronic text;
3. Receiving the output;
4. Analyzing what the electronic text does."

--Someone Writing about Their Reading of GoogleTechnacy Weblog)

I'm reminded of Espen Aarseth's definition of Cybertext -- a system that includes not only the array of bits in memory or phosophors on a screen, but the whole thing -- including the software used to create and view the text, the hardware (keyboard, mouse, monitor), the power grid that runs the whole system, and even (without stretching the point too much) the whole system of laws, guidelines and practices that control what sort of text gets created, distributed, rewarded, penalized, etc.

According to Jenkins, "Technacy primarily is about a new consciousness, an extended consciousness beyond oracy and literacy that encompasses the problems posed by a new language order - electronic language." I'm very happy I found this website. As soon as I get my course syllabi set up next week I'm goint to spend more time here.

"The MetroCard Vending Machines in New York's subways are a classical case of programmer-directed hierarchical menu hell, forcing the user to make choices without knowing the consequences, and throwing the user off altogether at the smallest problem. With a little careful thought, we are able to improve the interaction considerably, while at the same time extracting some valuable heuristics for interaction design. " Lars Pind

Submitted by my former student Matt Hoy, who writes: "Excellent write up, well thought out points. The reader responses at the bottom are a little troubling. Do people reall view usability reviews as 'attacks' on the current design? Is it normal for usability testers to encounter this kind of opposistion?"

--MetroCard MessPinds)

Yes, Matt, there's often a huge gulf between the brilliant "ar-TEESTS" who dream up fancy designs, and the usability trolls who seem to scour the underworld seeking the densest, stupidest users to botch up even the simplest transactions. In retail, the cusomter is always right -- even when the customer is obviously wrong. Good design does not try to force the user to behave a certain way -- instead, it watches the way people behave, and then builds a system so that people can use it effectively by doing what comes naturally. Pind suggested that it wasn't necessary for the New York metro subway vending machines to present the user with a language-selection menu first, but a reader comment pointed out that people will walk past a machine displaying the "wrong" language. So, Pind's suggestions can't all be taken without scrutiny -- and they would, of course have to be subjected to usability testing by a wide range of users. One good way to do that is to put two machines with different interfaces side-by-side, and see which one gets more use. Let's just hope somebody from the New York transit authority read the article and the reader comments.
