It was the “truck and company” that was cleared to cross. That’s probably 5+ vehicles you can see following the lead truck that were all approved. All while the jet was on short final. That controller lost situational awareness due to task saturation as a result of emergency aircraft on taxiway parallel to runway 13.

Me too. I had a secondary monochrome monitor just for the text commands.

Nice, and in that same plaza is Harbor Freight.

I believe one of the authors L. Peter Deutsch, is the original developer of Ghostscript.

I worked on a very capable unix based CASE system for Athena Systems in 88 & 89. There's still some articles about it online like here https://www.worldradiohistory.com/Archive-Electronics/80s/88... (complete with screen shots) on page 37. What I recall being the uphill battle was fighting the peace dividend granted by the cold war ending. Defense contractors, our primary market, we’re in cost cutting mode for a decade.

Flight radar shows a normalized approach where speed and altitude conform to that standard. I wonder if late wind shear was the issue.

I cannot find any evidence on IMDB or Wikipedia that he had involvement.

“BeOS did not have printing” was the insult thrown around at the time.

I think the intent is that water is a byproduct of combustion.

"Entropy is a property of matter that measures the degree of randomization or disorder at the microscopic level", at least when considering the second law.

If you want to get better at mathematical modelling in general I recommend a traditional text book dedicated to modeling, like the 11th edition of "Introduction to Operations Research" by Hillier and Lieberman.

As for the "mathematical equations" referred to by a parent, we're talking linear algebraic equations with perhaps a 2nd order term thrown in for quadratic models. I think these should be within the grasp of someone who wants to delve into the topic, and if not perhaps it's a good place to start dig deeper.

edited to be less of a prick.

In engineering text books, sure they use radians. In mechanical engineering design if you put a radian on a geometrical dimensioning and tolerance sheet it's not going to go well for you.

I suspect the same holds for civil engineering too. I have my doubts that radians are useful in chemical engineering, but I could be wrong there.

Hopefully the next part covers some of the compilers available on the 68k personal computers of the late mid to late 80s. MegaMax and Manx come to mind a some of the more prominent examples.

Considering the 4th edition of "Expert Systems: Principles and Programming" (The original book on CLIPS) is going for $300 at amazon, you are offering a good alternative.

I worked with Gary Riley and Joe Giarratano at JSC in the mid 80s when CLIPS was in heavy development. Joe had the unique ability to teach very technical topics with a special brand of humor.

Knowing CLIPs got me my first job in Silicon Valley / Los Altos in '88. Thanks Gary!
