Comment What about that stupid book is worth US$244? (Score 4, Insightful) 170

I really fucking hate this about academia. It's absolutely shameless to charge college students $244 for a single dumb textbook. It's not even that good. It's just that when a department chooses to standardize on a textbook, the move has inertia and is basically impossible to reverse. Then, the publisher can charge something absurd, and everybody pays it, because it is a required text. It's so dirty, because it's profiteering from people who are often barely making ends meet, and typically buying the book with debt.

What really bothers me is that nobody seems willing to do anything about it. If a big, publicly funded university system set aside some money to create and regularly update their core STEM curriculum textbooks - let's start with Calculus, Physics, GenChem, GenBio - it would certainly cost less than the almost $1000 per student that the textbook purchases cost. These universities have Nobel Prize winners among their faculty, surely they have the in-house resources to create excellent textbooks and distribute them on some sort of open license like CC. Arranging sabbaticals for the authors might cost at most a million dollars, or roughly 4000 Stewart Calculus books. That might be about the number of Calc 1, Phys 1, GenChem and GenBio books that are sold on a single campus in a single year.

But this move would help everybody, not just within the entire UC system that funded the effort, but across the globe. And the costs of updating and embellishing future editions would be far less. I'm so mad that a large university system doesn't just make this happen. And yes, raise fucking tuition by $200 to pay for it, if you absolutely have to. In exchange for textbooks you can have for free (or for printing cost if you don't like digital), everybody will recognize that's a great deal. The courses can explicitly invite students to devise problems for future editions, or to suggest changes and clarifications. And it will bring prestige to the colleges and to the authors, which is worth something too.

What? This is exactly the technology humans are trying to reach! We're already a significant way down this path!!

> Second, there is no evidence that we or anyone else can build intelligent machines, as the original story seems to presuppose.

Nature did it. We can do it.

> Third, biological organisms are so many orders of magnitude more efficient and flexible than machines that it barely makes sense to put them into the same qualitative category "form of life".

This whole conversation is about extrapolating on the cosmic scale. If you look at the path robotics has taken in the last century it does, as pointed out, actually support the premise of this article.

> Hint: A human consumes only about 2.9 kilowatt hours per day, the equivalent of 1-2 light bulbs ...

Not relevant. Once machines are replicating and repairing themselves they'll do exactly what we do and find other sources of energy.

Frankly I agree with you that it's hard to picture Transformers inhabiting the universe, but OP did make a really good point that extrapolation isn't even in the ballpark of refuting this clown. Honestly I'm shocked he didn't come back with that XKCD cartoon.

I'd be interested in knowing the details of the attack. Was it a "social engineering" attack of some kind (ie. a virus-laden email that someone with high privileges opened)? Was it a vulnerability in their networks? I've heard someone with high level admin privileges had their account hacked, but in what way was it done?

The organization I work for is a contractor for the government of a North American jurisdiction, and yesterday morning I started getting reports that some sort of virus-laden emails were flowing out of this government's networks. Sure enough, within a half an hour, I got emails from a contact I have within this particularly agency, with an attached ZIP file with an SCR file inside. That has to be one of the oldest ways that malware has been transmitted in Windows system, I saw my first virus-laden SCR file somewhere around 1997-1998.

Apparently this critter is so new that by the time we checked, only a few AV companies had caught on to it. Even worse in some ways is that it appears that it made its debut on the very government servers in question, making me think this was a targeted attack. So you have a combination of a brand new virus of some kind that won't get caught by the scanners, lax email rules that allow the opening and execution of executable file types (not that blocking EXE variants doesn't mean some bastard won't be firing off a compromised PDF at an unpatched system), and users who through a combination of laziness and ignorance happily take the final step.

With this particular attack, there would have been no problem if Outlook had been configured not to open these kinds of attachments, and in an Active Directory environment, that's pretty trivial, so some of the blame has to go to this government agency's IT team. But still, even with the best safeguards, where users just happily click on any old attachment, it doesn't exactly take a rare alignment of the stars to have malware planted in a network. Sure, it won't have root privileges and won't be able to propagate itself via more sophisticated means, but it appears in this case it didn't need to.

So I do agree to some point that there are finite limits to what any person or organization can do to secure itself against a determined and directed attack. But there are ways to make such attacks much more difficult, and more quickly captured before they wreak too much harm.

North Korea really hasn't even proven it has a missile that reliably reach Japan. The country is a total basket case run by a violent, completely detached dynasty. It represents a significant regional threat, but if it were to ever do anything truly belligerent, China would yank support and the regime would collapse.

That, to my mind, is the chief threat of North Korea, that when the Kims finally do lose grip, the regime's collapse will be violent for North Koreans and their neighbors.

Indeed. Of all the groups that make threats against the West, NK seems the one least likely to have the ability or desire to actually attack a Western target. I cannot imagine the fires of hell that would reign down on North Korea should it be demonstrated to be behind mass murders in the United States.

It boggles my mind that anyone seriously believes North Korea is going to start mounting attacks on North American theaters should they screen this film.
