Other than git-friendly, this is how I remember AutoCAD 10 from ancient times.

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

That link you posted there says 2025! Wow that makes me excited. Big fan of microcenter.

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.

I think most pilots could take one look at that approach and see they were coming in too fast. As many have said, that looked more like a carrier landing than an airstrip approach.

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

what his involvement with comedians in cars ?

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

As I recall, BeOS was asking on the order of $80 million, NeXT was acquired for $400 million.

I found this reference, so 80 valuation, Be wanted upwards of 200, “In 1996, Apple Computer decided to abandon Copland, the project to rewrite and modernize the Macintosh operating system. BeOS had many of the features Apple sought, and around Christmas time they offered to buy Be for $120 million, later raising their bid to $200 million. However, despite estimates of Be's total worth at approximately $80 million,[citation needed] Gassée held out for $275 million, and Apple balked. In a surprise move, Apple went on to purchase NeXT, the company their former co-founder Steve Jobs had earlier left Apple to found, for $429 million, with the high price justified by Apple getting Jobs and his NeXT engineers in tow. NeXTSTEP was used as the basis for their new operating system, Mac OS X.”

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

Oversimplifying, but you can explain that as "Because water is... the "ash" you get after burning hydrogen and oxygen."

I think the intent is that water is a byproduct of combustion.
stergios commented on What Is Entropy?   johncarlosbaez.wordpress.... · Posted by u/ainoobler
mitthrowaway2 · a year ago
Entropy is a property of a distribution, but since math does sometimes get applied, we also attach distributions to things (eg. the entropy of a random number generator, the entropy of a gas...). Then when we talk about the entropy of those things, those entropies are indeed subjective, because different subjects will attach different probability distributions to that system depending on their information about that system.

"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.
stergios commented on A practical introduction to constraint programming using CP-SAT and Python   pganalyze.com/blog/a-prac... · Posted by u/lfittl
jmjrawlings · a year ago
You totally nailed it. The actual syntax / API of constraint solvers are so simple they can be learned in no time at all. What actually takes time and expertise is modelling problems in this fashion and there are almost 0 real world (in size and complexity) examples out there for others to reference.

I have about 5 years of experience in MiniZinc solving scheduling problems but sadly all that code is locked behind closed doors never to be open sourced. I would love put together some fully worked constraint programming examples complete with containerisation / visualisation/ modeling etc but the barrier to doing so is finding problems that are actually worth solving and have open source data to work on.

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.
