I’ve been looking at computer graphics and engineering CAD systems for most of my life. I’ve been a more or less continuous user of CAD systems for over thirty years now and I thought I knew most of how it came about. There have been things I never really understood about how the way things worked in CAD as opposed to how a designer or drafter thinks, but I didn’t think to look into that very deeply.
These old stories tend to be cautionary tales. Even if they are just the businesses that posted those ads in the back of comic books. These stories always end in the greedy stupid part of the human story. And tragedy all around.
Pratt has finally completed it’s geared bypass engine for commercial aircraft. The development for this engine has been going on for a long time. There are reasons for that. Some of it’s FAA red tape. The biggest part though, is the expected long life of the engines themselves.
It’s not like the old days where you did all your development in a backshop. Of course the aircraft aren’t enlarged kites anymore either.

He makes some very good points about how the end of Moore’s law has come for processor speed. The end of shrinking the gate size is coming shortly as well. Not necessarily because the physics don’t work but because the machines to make the transistors will have gotten prohibitively expensive. It seems that there was another exponential in Moore’s law.
I ran across this blog post recently. It’s an overview of all the sorts of space suits out there.
I’ve since found an amazing amount of stuff and links, most of which will end up in this post. I think that, if nothing else, this post demonstrates the power of the internet for research. When I was in school finding information on this scale would have been impossible.
Behind every great innovative product there’s an innovation story.
Overcoming obstacles, drive and being willing to make the compromises to make it work is a common thread in these stories.
