Consider the digital wristwatch: people generally care less about knowing the time to the nanosecond than about seeing how long they've got until lunch. Some experts say the solution to this predicament is user-centered design. Elementary as that sounds, it could drastically revamp American business. (SOURCE: "The Complexity Problem," John Sedgewick, The Atlantic, March 1993, p.96) ===================================================================== The Art of Programming A program should be light and agile, it's subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little nor too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity. A program should follow 'The Law of Least Astonishment.' What is this law? It is simply that the program should always respond to the user in the way that astonishes him least. A program, no matter how complex, should act as a single unit. The program should be directed by the logic within rather than by outward appearances. If the program fails in these requirements, it will be in a state of disorder and confusion. The only way to correct this is to rewrite the program. (from The Tao of Programming by Geoffrey James [Info Books, 1987. ISBN 0-931137-07-795. $7.95]) ====================================================================== It's No Secret Three years ago, Mitch Kapor stood up at Esther Dyson's conference and spoke about the "secret shame" of the PC industry: PCs were too hard to use, and none of us was willing to admit it. Mitch was right. We were all participating in a shameful scam - pretending that computers were easy to use when most of us knew differently from personal experience. ("The Secret Shame of Client/Server Development," Patricia B. Seybold, Computerworld, 8/9/93) ====================================================================== How To Really Screw Things Up According to the book _The Design of Everyday Things_ by Donald A. Norman (see B&B Bookshelf), here's how to really mess up a system design: MAKE THINGS INVISIBLE. Don't let the user know what operation to do, and don't offer feedback. Do not provide a help function. BE ARBITRARY. Pick command names and user actions that don't make intuitive sense. See how many alt-shift-cntl-PFkey functions you can come up with. Be creative. Neatness does not count. BE INCONSISTENT. Use a bunch of different rules. Create inconsistency in the way things are done in different modes. MAKE OPERATIONS UNINTELLIGIBLE. Use unusual language, abbreviations, and cryptic error messages. ("One item could not be deleted because it was missing." - Mac System 7.0b1 error message) BE IMPOLITE. Treat users like the pond scum you know they are. MAKE OPERATIONS DANGEROUS. Make it easy to destroy important work. Do *not* provide an undo function. On the other hand, if good design is considered a plus at your shop, the following qualities may be desirable: VISIBILITY. Tell the users what's going on and what their options are. A GOOD CONCEPTUAL MODEL. Try thinking about the problem at hand for a while *before* you start to code. Talk to the users about the process you are trying to codify. GOOD MAPPINGS. Users can help determine the relationship between actions and results; controls and effects; and the system state and what is visible on-screen. Yes, the user is your *friend*. FEEDBACK. Let the users know the results of their actions. GOOD ERROR HANDLING. "If an error is possible, someone will make it. The designer must assume that all possible errors will occur and design so as to minimize the chance of error in the first place, or its effects once it gets made. Errors should be easy to detect, they should have minimal consequences, and, if possible, their effects should be reversible." (Donald Norman) (SOURCE: Computerworld, 7/5/93, p.72) ====================================================================== Mainframe Continues Its Death Throes Forrester Research, Inc. has released a report entitled _The Mainframe's Fate_, which concludes that mainframe computers, once the mainstay of corporate computing, are slowly fading into irrelevance. Despite what diehard 'big iron' supporters may say, as the world moves to client/server computing, distributed computing and smaller, cheaper hardware, mainframes will put out to pasture. In fact, some already have been and many more will follow. Of the fifty Fortune 500 companies surveyed, 10% had already pulled the plug on their mainframes, and another 18% were actively seeking to reduce their dependence on mainframes. The report does not, however predict the mainframe's extinction any time soon. It will continue to see some use as a central data warehouse. However, a new class of corporate servers will emerge using the most powerful of today's processors, in many cases using multiple processors. These will probably pound the final nail in the coffin and bring to end the stone ages of the Information Age.

Hi - oooooh! =-=-=-=- Q: What is the difference between Jurassic Park and IBM? A: One is a high-tech theme park for dinosaurs and the other is a movie by Steven Spielberg. Ba-bing! ====================================================================== NEW PRODUCTS AND SERVICES: +BLUE LIGHT SPECIAL. Here's a little more information on the new laser from IBM (B&B v1#4). The blue light laser based system could put 6.5 gigabytes on a 5-1/2 inch optical disk. This is 5 times the density of current devices. IBM scientists hope to have a commercial version of this technology in 4 or 5 years. (SOURCE: Computerworld 8/9/93, p. 31) +NEWTON IS HERE. I would be remiss if I did not mention that Apple's Newton Message Pad is out at last. The verdict is not in yet - I have seen both glowing praise and less than wonderful reviews of the most prominent of a new breed of personal digital assistants (PDAs). The $700 package learns to read your handwriting, will automatically add an appointment to your calendar based on a note, or dial a phone or send a fax. Future versions will feature wireless messaging capabilities. Currently Newtons can talk to each other via infrared links. Third party manufacturers will be providing add-on products and software to extend the Newton Pad's functionality. Keeping in mind that these devices are in their infancy, I expect to see Artificial Intelligence techniques applied to these gizmos, making them true personal assistants in the future, capable of initiating actions with minimal input from the user. For example, the head office schedules an important out of town meeting at the last minute . Your PDA sees it is a priority one event. It books a plane flight, adding the flight information to your calendar, informs the office via email that you won't be at the office tomorrow, reschedules meetings by sending participants a message, perhaps checking with their PDAs for a convenient time, and updates your schedule accordingly. For us more academic types, PDAs will initiate searches for citations or other pieces of information needed from the networks. More on PDAs and intelligent agent technology in an upcoming B&B ONLINE. +THE MOTHER OF ALL STORAGE DEVICES. A commercial patent has been granted to EMASS corporation, for a technology that can store up to 10,000 terabytes of computer data in a device called the DataLibrary archive. A terabyte is one trillion bytes, or the equivalent of about 500 billion pages of text. For those with more modest storage needs the company plans to offer the Data Tower archive, a phone booth-sized structure that stores 6 terabytes of data. The high-speed ER90 tape drive can operate at 15 megabytes per second, and the D2 DataCassettes store up to 25 gigabytes on a VHS-size cassette. Mind you, the machines are not ready to ship yet, and the technology is not cheap. A six terabyte system will cost over $1 million, depending on the configuration of the system.

Sega will be releasing the first mass market virtual reality product in time for Christmas gift-giving. The Sega Virtual Reality Stuntmaster, a combination goggle/headphone add-on for the Sega Genesis game system, will retail for about $200. It comes with a game called "Nuclear Rush," that will put users in the middle of the action, with 360-degree stereoscopic view and realistic sound placement - you'll be able to hear them gaining on you. (SOURCES: Philadelphia Inquirer, Tower Records Pulse September 1993) +FREE EMAIL SYSTEM. Pegasus Mail, or PMail, is a native Novell Inc. Message Handling Service (MHS) mailer that does not require Novell's MHS to run. It runs on the PC and MacIntosh platforms. The program's developer, David Harris, first released PMail in 1990, and currently supports the product over the Internet with the aid of the PMail User's Group. Though the program is free, Harris sells licensees to make unlimited copies of the manual for $275 "to cover development costs." The article I am reading goes on to quote enthusiastic users who say the package is better than many commercial offerings. Users include the state government of Minnesota, the Department of Defense/ Navy at Charleston SC, Cambridge Systematics in Cambridge MA, and Alberta Power, Ltd. Version 3.0 is due out this month.

The Walt Disney Co. took its first small step online, as its Disney Adventures magazine signed to make the publication available through the America Online service. They join Time Magazine (B&Bv1#4), WIRED Magazine (B&Bv1#3), Cable News Network, The San Jose Mercury News, and Knight-Ridder and Tribune newspapers, all of which have or will soon have online versions on America Online. Industry analysts predict that major media companies like Disney and Time Inc. will be major players as content providers to the online market in coming years. Alliances with existing online companies are the first step toward reaching this growing market. In a related story, Disney Computer Software has also entered into a three-way alliance with Sega Enterprises and Virgin Games to develope movie- based game software for Sega's pocket game machine. The first product, due in October, is a game version of Aladdin, Disney's hit movie, and will feature high resolution, fast moving animation at a rate of 60 screens per second. This is more than twice the speed of a television or a movie. Disney animators will provide the animation. (SOURCE: Newsbytes News Service 8/5/93, 8/10/93) ====================================================================== Highway To A Wasteland? Will the cost of the much ballyhooed data superhighway - as much as $25 billion - encourage the risk-sharing alliances of cable, computer, and telephone companies to try to recoup their investment by focusing entirely on sales of movies, home shopping, and interactive games at the expense of consumer control? "Unless some social or public interest goals are established now, I'm afraid this information superhighway will simply end up deepening the ocean of commercialization that we have fallen into," says Berkeley journalism professor Ben Bagdikian. ("What So Proudly We Logged On," Tom Abate, San Francisco Examiner, 7/4/93, p. E1) ====================================================================== IRS Employees Caught With Their Hands In The Electronic Cookie Jar An internal IRS report reveals that almost 370 IRS employees at the regional headquarters in Atlanta have been snooping into taxpayer records - just for kicks. They were examining the personal tax records of friends, enemies, neighbors, and even celebrities without agency authorization. The more ambitious ones even set up a side-line altering reports which resulted in lower tax obligations in exchange for payments. Many civil-liberties concerns have been raised over the move to provide more information online so government agents and the public can quickly access more information. Not surprisingly, it looks as if these groups are right to be concerned. Nearly half of the more than 100-thousand IRS employees currently have access to these files, and if the same pattern applies to the other regional offices, it is possible that more than 1,000 IRS employees may be routinely be looking at private records. Sen. John Glenn (D- Ohio), chairman of the Senate Governmental Affairs Committee, is calling for an expanded investigation. Two employees have already been indicted, and as many as 80 others are under investigation for possible criminal prosecution.

Held near Disneyland in sunny Anaheim, California, games, entertainment, and education were the themes of the show. Highlights included: - The Silicon Graphics exhibit, inspired by the movie Jurassic Park, which gave show goers a chance to enter a giant box and climb into a saddled teradactyl. Of the groups who entered the box only three were allowed to actually ride, but onlookers saw the virtual scene as well. - Evens and Sutherland offered a chance to take a virtual hang-glider ride through a crowded city-scape. Participants were helped into body-length slings that hung them suspended in front of a viewing screen. They controlled their movement through the space via a hang- glider bar they grasped with both hands. Stereo speakers provided the sound. Riders reported that the sensation of hang-gliding was very real despite the comic book appearance of the city landscape through which they flew. - In the electronic art area, sinners of all denominations could stop in at an electronic confessional. Based on the confessions of the Catholic church, the automated religion kiosk, called "Catholic Turing Test" by Gregory P. Garvey, was a thin, shiny, black plastic structure with a red neon cross at the top and a red kneeling bench in front. The program started by asking how long it had been since you'd last been to confession (answers were typed in). Sins were then selected from a menu and penitents were told at the end of the confession what type of sins they were and how many "Hail Marys" were needed for penance. I swear I'm not making this up. - At a group of tables, show goers who sat down to relax were eventually bumped and mumbled at by what appeared to be a giant bowling ball. Called "Adelbrecht" by designer Martin Spanjaard, the mobile robot moved around under its own power, bumping into chairs and people, changing direction all the while making beeping and whirring noises, and mumbling unintelligible speech to show goers. - The "Neuro Baby" was a monitor in a crib that displayed a pink, cartoonish, buggy-eyed "baby" face that bounced around on the screen and responded to attendees who bent down to speak into a microphone by the crib. The baby laughed, cried, said "Hi," rolled its eyes, and even got red-faced mad when the Newsbytes reporter laughed at it. The voice analysis was performed by a neural network emulator that converted voice input into "emotional" patterns to which the computer had been "taught" to respond. A Silicon Graphics Iris 4D was used to generate the image of the baby. There were also lectures and conferences and a well stocked job postings board to be found at SIGGRAPH. The keynote speaker was Trip Hawkins, president, chief executive officer (CEO) of 3DO, and chairman of computer game maker Electronic Arts. SIGGRAPH '94 has been announced for July 24-29 at the Orange County Convention Center in Orlando, Florida.

Norman [Basic Books, 1988. $24.95] Things That Make Us Smart: Defending Human Attributes In The Age of The Machine by Donald A. Norman [Addison-Wesley, 1993. $22.95] - Two books that belong on every designer's shelf. In a world of VCRs with their clocks perpetually blinking at 12:00, cognitive scientist Norman explains how to design things that work *with* human nature instead of against it as so many objects and programs do. Filled with many amusing anecdotes we can all relate to, these books entertain and teach good design principles. The second book is more computer- oriented. (from Dijanta Majumder's review in Information Week, 5/31/93, p.66): Norman says he's Pro-human rather than anti-technology, and his book celebrates human foibles: "A machine is not distractible: My computer will continue doing its job even as the building burns down... We might rejoice in the fact that people are attentive to their surroundings and to new events." ====================================================================== Kick Them Even If They're Not Down Department Q: What is the difference between Jurassic Park and Microsoft? A: One is a high-tech theme park dominated by expensive, nasty, hungry, predatory monsters that will destroy anything they can get their teeth into... and the other is a movie by Stephen Speilberg. ====================================================================== ### ADMINISTRIVIA ### REQUEST FOR CONTRIBUTIONS. Start spreadin' the news... B&B is always on the lookout for interesting material for publication. In September I am planning a 'theme' issue on education, retraining, and lifelong learning. Do you have any interesting snippets along those lines? I have a scanner, the material need not be in an electronic format. Send paper to my snailmail address. Contributors will be gratefully acknowledged. Speaking of which... THANKS! The person who contributed the Picasso quote at the top of v1 #4 was Philip Fitzgerald. Thanks, Philip! There's a room with your name on it in the pink pyramid of love. Thanks also to Craig Dunn from the Almac BBS (the largest online service in Europe) for turning me on to the Usenet newsgroup alt.quotations. The two Jurassic park riddles came from the August '93 edition of RAndY s RumOR RaG, an electronic magazine available on various local BBS's, GEnie, and America Online as well as in Modem News.
