VisiCalc Turns 25, Creators Interviewed
Xaroth writes "It's hard to believe that it's already been 25 years since the release of one of the world's first 'killer apps.' 1979 saw the creation of VisiCalc, the first microcomputer-based spreadsheet and the single application that launched widespread computer use among businesses.
To remember this event, PC World has published portions of interviews with the three co-creators of the modern spreadsheet: Dan Bricklin, Bob Frankston, and Dan Fylstra. Alternately, check out the Software History website for more information on this and other historical bits."
What's the difference between what you describe and the idea of Lotus Improv?
Improv was a truly innovative system, which I think represents a logical method of fast data handling.
Also, could jEdit have been developed if VisiCalc and Improv had not come before it?
ah, mod points
Not to be a flaimbait or anything, but I think that your completely wrong about Visicalc. Computers aren't designed to mimic things from the real world. Many good programs don't. The spreadsheet is productive, very. In fact, it doesn't mimic paper+calc+pencil for doing banking, it superceeds it.

I agree with you, but we're both probably spreadsheet experts. Have you ever seen a user with only basic training, and a limited understanding of math? They know certain things are possible (because they saw us do them) but to them the spreadsheet is not intuitive. To us they are. Once you grasp relative v absolute references (and cell naming) you are usually on your way to being unstoppable.
One thing that would be nice would be a sheet that had a different display for user input data and calc'd data (I have my own shorthand but wouldn't it be nice if the sheet just formatted them automatically?
My employer spend millions of dollars redesigning their database input and report forms so they would be the same as the old mainframe systems. Dumb to us, but most users were rendered helpless by something different, even if it was more efficient. Something that looks like what a user is comfortable with is sometimes more useful than a powerful, flexible, but different tool.
Degaussing scares the bad magnetism out of the monitor and fills it with good karma.
Not only that, but the original designer of VisiCalc describes this very issue in the article, and how the uniqueness of the spreadsheet made it very difficult to describe to the public at large. Only through immersion in the technology can you really understand and appreciate it.
so, you forgot to preface your post with RTFA.

The GPL does nothing to prevent anybody from writing their own version not using any GPL'd code. The GPL wouldn't have stopped anything in this case.
If you reply, do so only to what I explicitly wrote. If I didn't write it, don't assume or infer it.
