Re: Bill Atkinson has died
#152In an alternate timeline, HyperCard was not allowed to wither and die, but instead continued to mature, embraced the web, and inspired an entire genre of software-creating software. In this timeline, people shape their computing experiences as easily as one might sculpt a piece of clay, creating personal apps that make perfect sense to them and fit like a glove; computing devices actually become (for everyone, not ju…
It is a custom system that didn’t require any code (if you don’t count the very minor bits of regex (just a lot of stuff like… ^\s- .).
Is it a good system, probably not, but we’ll see where it goes.

> In fact the folks at PARC had never accomplished it, and they later told him they were amazed that he had done so. Reminds me of the story where some company was making a new VGA card, and it was rumored a rival company had implemented a buffer of some sort in their card. When both cards came out the rival had either not actually implemented it or implemented a far simpler solution
An infamous Starcraft example also contains notes of a similar story where they were so humbled by a competitor's demo (and criticism that their own game was simply "Warcraft in space") that they went back and significantly overhauled their game. Former Ion Storm employees later revealed that Dominion’s E3 1996 demo was pre-rendered, with actors pretending to play, not live gameplay.

#154From Walter Isaacson's _Steve Jobs_: > One of Bill Atkinson’s amazing feats (which we are so accustomed to nowadays that we rarely marvel at it) was to allow the windows on a screen to overlap so that the “top” one clipped into the ones “below” it. Atkinson made it possible to move these windows around, just like shuffling papers on a desk, with those below becoming visible or hidden as you moved the top ones. Of cou…
Would someone mind explaining the technical aspect here? I feel with modern compute and OS paradigms I can’t appreciate this. But even now I know that feeling when you crack it and the thrill of getting the imposible to work. It’s on all of us to keep the history of this field alive and honor the people who made it all possible. So if anyone would nerd out on this, I’d love to be able to remember him that way. (I did…
Back at the time, there wouldn't be enough memory to hold a copy of the full contents all possible windows. In fact, there were actually zero abstraction layers: each application was responsible to draw itself directly into the framebuffer (array of pixels), into its correct position. So how to handle overlapping windows? How could each application draw itself on the screen, but only on the pixels not covered by other windows?
QuickDraw (the graphics API written by Atkinson) contained this data structure called "region" which basically represent a "set of pixels", like a mask. And QuickDraw drawing primitives (eg: text) supported clipping to a region. So each application had a region instance representing all visible pixels of the window at any given time; the application would then clip all its drawing to the region, so that only the visibile pixels would get updated.
But how was the region implemented? Obviously it could have not been a mask of pixels (as in, a bitmask) as it would use too much RAM and would be slow to update. In fact, think that the region datastructure had to be quick at doing also operations like intersections, unions, etc. as the operating system had to update the regions for each window as windows got dragged around by the mouse.
So the region was implemented as a bounding box plus a list of visible horizontal spans (I think, I don't know exactly the details). When you represent a list of spans, a common hack is to use simply a list of coordinates that represent the coordinates at which the "state" switches between "inside the span" to "outside the span". This approach makes it for some nice tricks when doing operations like intersections.
Hope this answers the question. I'm fuzzy on many details so there might be several mistakes in this comment (and I apologize in advance) but the overall answer should be good enough to highlight the differences compared to what computers to today.

Maybe there's some sense of longing for a tool that's similar today, but there's no way of knowing how much hypercard did have the impact you are talking about. For example many of us reading here experienced HyperCard. It planted seeds in our future endeavors. I remember in elementary school, I had some computer lab classes where the whole class worked in hypercard on some task. Multiply that by however many classro…
HyperCard was undoubtedly the inspiration for Visual Basic, which for quite some time dominated the bespoke UI industry in the same way web frameworks do today.
I was on the team that built Ruby (no relation to the programming language), which became the "Visual" side of Visual Basic.
Alan Cooper did the initial design of the product, via a prototype he called Tripod.
Alan had an unusual design philosophy at the time. He preferred to not look at any existing products that may have similar goals, so he could "design in a vacuum" from first principles.
I will ask him about it, but I'm almost certain that he never looked at HyperCard.

There probably still isn't a good way to get that kind of dynamic range entirely in the digital domain. Oh, I'm sure the shortfall today is smaller, say maybe four or five stops versus probably eight or twelve back then. Nonetheless, I've done enough work in monochrome to recognize an occasional need to work around the same limitations he was, even though very few of my subjects are as demanding.
I wish a good monochrome digital camera didn't cost a small fortune. And I'm too scared to try to remove the Bayer grid from a "color" CCD. Seems that, without the color/Bayer thing, you could get an extra stop or two for low-light. I had a crazy notion to make a camera around an astronomical CCD (often monochrome) but they're not cheap either — at least one with a good pixel count.
Re: Bill Atkinson has died
#158I know nothing about the fundamentals of “old computing” like what Mr. Atkinson worked on as I am only 27 and have much more contemporary experience. That being said, I still very greatly mourn the loss of these old head techs because the world of tech I use today would not have been possible if not for these incredibly smart and talented individuals. To learn to code without YouTube is truly a feat I could not imagi…
Re: Bill Atkinson has died
#159For anyone (like me) wondering who this guy was, he was a prominent UI guy at Apple back in the day. According to Wikipedia he created the menu bar, QuickDraw, and HyperCard. For whomever submits stories like this, please say who the person was. Very few people are so famous that everyone in tech knows who they were, and Mr. Atkinson was not one of them. I've heard of his accomplishments, but never the man himself.

> I have to say that I mused at the time about a wealthy, retired, engineer who throws money at high end photo gear and suddenly thinks they're a photographer I think this says more about you than it does about him
This is absolutely true and I don't understand why you're being downvoted. Especially in the context of this man just recently dying, there's someone throwing in their elitist opinion about photographers and how photography SHOULD be done, and apparently Bill was doing it wrong.
