Comment Re:Missing the point a bit? (Score 3, Interesting) 112

i'm really curious about what could possibly be the use case for this. it seems like a giant pain-in-the-ass way to do symbolic algebra, so i'm trying to figure it out. apparently you need to regularly perform symbolic derivations which mma can do, but the free alternatives (octave, sage, etc.) cannot; however, your uptime and latency requirements are low enough that you are willing to deal with a duct-tape ssh solution. i really have no idea why anyone would want to do this. care to enlighten me?

Yes, they do "get to keep what they bought". Some of these things are significantly less useful without the service they subscribed to, but it is hard to say what the actual damage of that is, especially since I'm sure it was in the fine print of the EULA that the service could be shut down at any time with no implied liability. iTunes will start supporting the devices eventually, at least for long and just well enough to stave off a class action suit.

Well, PCs have been well overpowered for most "work" for well over a decade, since most of the "work" done on an average computer is office apps. The past two decades of home computer progress have been mostly for aesthetics (you have to do a lot of computation to get computers to feel responsive and look pretty) and video gaming. Now that the improvements on those fronts are yielding rapidly diminishing returns, and battery technology is picking up, it only makes sense to go for portability.

Numerical computation and programming are pretty rare work. If computers were bought and sold just for that, the market would be far smaller.

The curriculum in a math class like this one is rarely determined by the book. Introductory Diff Equ and Linear Algebra haven't changed in, like, 40 years. The topics are always the fucking same, every book covers all of them. Frankly, more variation in topics covered comes from the professor, than from the textbook used.

Your point about seniority is, sadly, correct, but let's not pretend there's a good reason for it. It's just graft and ego-stroking.

btw, Associate Professor is not a low title. In North America, the ranking is usually: Adjunct, Assistant, Associate, Full. Even as a lowly adjunct, I had say in choosing my own textbook; this probably had something to do with the department chair not having written the incumbent textbook. Frankly, to not allow an Associate Professor to select their own textbook is quite insulting to everyone. If they are so incompetent as to not be able to choose their own classroom material, then how the hell did they become an Associate Professor?

I can't even respect this as an evil scam. The book is published through Pearson-Prentice Hall, which means Goode and Annin are pulling in peanuts in royalties while basically doing all of the dirty work.

If they weren't lazy bastards, they could have just self-published, charged $50, saved their students money, and still gotten out ahead! But no, that would be almost like real work, and would detract from their precious pontificating time. Typical third-tier academics with their heads up their asses.

Well, that was just a few episodes.

The more entertaining part is how nearly every goddam week, the crew of Enterprise discover a phenomenon which, if studied, understood, and engineered, would change society forever. Hell, sometimes the crew even invent it themselves out of desperation. but the next week? Gone, like it never happened. What the fuck is wrong with these people? I understand that technology is supposed to be advanced to the point where most people don't "need" anything more, but clearly some people do, since we see their continuing difficulties. Just write this shit down and send it to the scientists at Starfleet. Surely someone would eventually figure out every possible way to "invert polarity" and just program the computer to do it automatically.

I mean, the crew accidentally invented a supergenius AI one time by unwittingly asking the computer to do it for them. Then they defeat Moriarty, and presumably everyone agrees to forget about it for some reason. Fucking hell. You'd think that if a single enterprising Ferengus got hold of a Federation ship, they could probably take over the galaxy (or at least kill themselves in spectacular fashion).

They sort of tried to do something with continuity when they introduced transwarp, but apparently got tired of it pretty quickly. The sad fact is that Star Wars has more inter-episodic consistency than Star Trek, partly by aspiring to a lot less.

The slashdot summary includes only the victim's name as "evidence" of his race or religion.

Further, what do the details matter? Whenever stories like this appear, they tend to involve an outsider of some sort or another; the "white kids" are rarely jocks or cheerleaders. Whether it's a pocket protector-wearing über-nerd, a trench-coated psychopath misfit, or a rag-headed mudskin, it's all the same evidence of prejudice in its literal sense of "pre-judging".

Most of the comments are just inferring context to speculate on the motivations and outcomes of this event, which is the same thing we do when it's a "white kid".

It's great that you can try to refocus this article onto "anti-Christian hatred" though; it shows real effort and creativity on your part.
