That may be true
Things will get pirated. It's undeniable. I'm also not familiar with Pogue's writing.
But 99% of what I need to read is already freely available on the internet not only because of books, but also forums about specialty topics, news sites and things of that nature. Years back, when I was looking to learn lisp I found the easiest/best book was available free (by Touretzky).
And several newer ones (and highly acclaimed) were freely available as well. They sold well when they made it to print.
The way I see it, good books/resources are already so widely available on the internet that authors are shooting themselves in the foot by not putting themselves out there on a digital format. It's rather like refusing to print books because the library offers them for free and they can be xeroxed.
They don't have to compete on price, but just be better than the free competiton. I know I would be more apt to buy a book on computer languages written by Touretzky. I know this because I have been a repeat customer of other authors I like from fiction to mathematical textbooks -- my time is more valuable than trying to cop a free book. If I know an author can entertain/teach me in the allotted time, I'll pay the price.
When you consider the average American moves every 7 years, the hassle of libraries, the expense/convenience of keeping a paper library, and the inherent advantages of a digital e-ink readers; these will become a major market soon especially for the younger generation.*
It's rather like artists/RIAA of the 90s saying they wouldn't put their music out as mp3s because of piracy, they'll stick with the good old CD. The format exploded despite the content providers liking it or not.
*(Although I have dealt with DRMed digital textbooks, I won't have anything to do with them. IMO, DRMed books are a million times worse than a DRMed song. Stallman was right on the money here.) -
Re:What about the 2nd?
Not to mention that in the early US history, it was routinely upheld that states had the right to regulate weapons (the issue didn't come to a federal level until much later).
US v. Cruikshank and Presser v. Illinois said that the 2nd Amendment applied only to the federal government. However, these cases pre-dated incorporation of the Bill of Rights via the 14th Amendment against the states (see below).
However, Presser v. Illinois stated that there is a limit upon state restriction of firearms ownership:
It is undoubtedly true that all citizens capable of bearing arms constitute the reserved military force or reserve militia of the United States as well as of the States, and in view of this prerogative of the general government, as well as of its general powers, the States cannot, even laying the constitutional provision in question out of view, prohibit the people from keeping and bearing arms, so as to deprive the United States of their rightful resource for maintaining the public security, and disable the people from performing their duty to the general government. But, as already stated, we think it clear that the sections under consideration do not have this effect.
However, Quilici v. Village of Morton Grove disposed of this as "dicta quoted out of context", and the US Supreme Court denied cert for the appeal.
Items generally restricted were weapons designed to be easy to conceal -- pistols, dirks, cane swords, etc.
One of these (Aymette v. State of TN), was cited by the Court in US v. Miller -- relying on the phrase "for the common defense" in the state constitution. However, that particular phrase was explicitly rejected by the US Senate during the debate of the Bill of Rights, as it may have been enough for some of the ratifying states to reject it.
Often there were commonsense exceptions -- in Arkansas, they left an exception for those who were "on a journey", for example.
It sounds like "common sense", until you understand the reason behind it and similar laws in the South. We had the same exception in Texas law, but it was really code for "if your skin is the right color". For almost a century, state and local law enforcement used it as a discretionary method to enforce the prohibition against carrying weapons against people they didn't like. When anti-gun police chiefs in Texas started enforcing the prohibition against the white majority in the large cities, popular support for a non-discretionary CHL law grew until it was passed in 1995.
An interesting piece of trivia: Texas Governor Ann Richards publicly threatened a veto of a CHL law if it was sent to her desk. That act was widely credited as a substantial contributor to her defeat in the subsequent 1994 election. The winner of that election was George W. Bush, whose only prior political asset was his name.
I think there could be a legitimate argument made that the federal government doesn't have the right to regulate weapons without constitutional amendment (it depends on the reading), but you'd be hard-pressed to support that line of argument in relation to the right of states to do so.
It depends on the interpretation of the 14th Amendment.
Although the authors of the 14th Amendment explicitly said it was intended to apply the first 8 amendments in the Bill of Rights to the states, the Supreme Court declined to interpret it that way, and has instead been incorporated the Bill of Rights piece-meal, as the cases are brought before them.

Mind Reading Computer?!Yet again we see a jounalist dumbing down scientific research into tabloid fodder.
What the CMU scientists have done is some preliminary brain imaging using MRI.Here is a better CMU link with more details and pictures. The scientists hope that this research to could have applications in the study of autism, disorders of thought such as paranoid schizophrenia, and semantic dementias such as Pick's disease. Not once did they ominously dub their research as "mind reading" as claimed by the submitter.

There's a CMU press release about it.

Re:Does a clean architecture matter?
Premature Optimization is the root of all evil.
I've never seen anything saying otherwise.
Follow any of these sets of rules:
http://c2.com/cgi/wiki?RulesOfOptimization
http://schwern.org/~schwern/talks/What_Works/What_Works/slide016.html
http://www.cs.cmu.edu/~jch/java/rules.html
Or my version--
1) Don't optimize, no really, don't.
2) If you absolutely have to, write it unoptimized, test it, write it optimized, then:
2a) If the first is anywhere in the ballpark, throw away the second,
2b) If the second has enough of a proven, documented speed gain to get you past some accept/no accept barrier, comment out the slower one, but keep it so the next guy can follow the "Good" code.
If you don't document exactly what you did in the code and why, I'm going to refactor it into something readable the second I see it.
Also--know how to program. Choosing a linked list instead of an array list for an insertion sort is just programming correctly. It's not an optimization.

medium contrast; medium saturation
If you stare at text all day long, I've found that high contrast (black on white default) and high color saturation (brightly colored syntax highlighting) is very tiring. Turning both down a notch goes a long way for extending readability.
My terminals all use a light white on dark grey scheme, and my preferred vim color scheme has been ps_color for quite a while. (here's a useful site for visually comparing a ton of color schemes (in iframes) all at once: http://www.cs.cmu.edu/~maverick/VimColorSchemeTest/. ) -

what others have saidA few of these things only sound bad, but once you do the analysis are not a problem at all. Hard to tell which unless you think hard (which is called science) or read the reports of others who've thought hard: Sometimes I find myself wondering if there are alien civilizations close enough to supernovae, or black holes (which emit intense x-rays), A near-by supernova explosion would be absolutely catastrophic, as would straying into the particle stream ejected by a black hole. No good way around that without interstellar flight, so you're pretty much right. Using statistical arguments combined with the known movement of the solar system through the Milky Way along with stellar evolution and the resulting likelihood and expected proximity to Earth of supernovae, there are some astronomers/geophysicists/paleontologists who posit a correlation between major extinction events in Earth's history. For suitably chosen values of the incidence of supernovae over a suitably chosen model of galactic evolution (and thus star formation), and suitably chosen "major" extinction events, this is an intriguing possibility. You can draw a phase clock of extinction events and see a clustering (a "most common" approximate periodicity). or are in galaxies which suffer collisions, This actually isn't a problem, although it sounds bad at first blush. Galaxies do of course collide, but the individual stars are so vanishingly small in comparison to their distribution (i.e. they are sparsely distributed) that they essentially never collide. Another way of saying this is that what physicists call the "mean free path" of the particles (stars in this case) is much longer than the scale of the collision. Think of what would happen if you and a friend simultaneously threw a pinch of sand at each other from a distance of many times as far as the moon. In the analogy the grains of sand will be dispersed throughout many cubic miles/kilometers of space by the time the pinches "collide", so you will not be surprised that none of the grains themselves collide. With stars and galaxies, the only interaction among the stars is the gravity of each on every other star. The collisionless nature of galaxy interaction is why we use particle-particle simulations to model galactic collisions: it's the N-body problem and it requires cleverness to avoid the n^2 complexity inherent to the problem.
Look here for some pictures and a little more exposition:
http://www.galaxydynamics.org/spiral_metamorphosis.html
And for cosmological-scale stuff:
http://web.phys.cmu.edu/~tiziana/BHCosmo/ or whose home planets are hit by comets. Technology to survive this threat is much less than you think. It's been available to humans since around 1960-1970. Orbital mechanics was well-established 50-100 years earlier. You just need chemical rocketry and Newtonian mechanics to avert such an ecological disaster; you don't need to abandon the planet or star system. If you can do the latter, you can certainly do the former. It seems like catastrophes on an astronomical scale are fairly common; "Common" is relative: it "seems" to me that the occurrence of an extinction-level event on inhabited worlds is relatively rare compared to the time it might take an intelligent species to progress from speciation to advanced space flight; say, 10^5 to 10^6 years. Even if there are few such intelligent species, they will seldom, if ever (statistically speaking), be wiped out by such an event because such an event is incredibly improbable during the tiny window between their initial existence and their developing the means to avert such a disaster.
Of course, statistical models are not physical reality; it might certainly happen occasionally even if you statistically predict "never". Some star might get lucky and bull's-eye another star in a galactic collision. -
This is a "false flag" tactic by Scientology
http://en.wikipedia.org/wiki/False_flag
The cult is doing this to make Anonymous look bad.
I used to be a Scientologist, and I can tell you based on first hand experience that this is EXACTLY what the cult would do.
This is not the work of those who fight and oppose the cult of Scientology.
The cult has already taken to creating fake videos and messages that appear to be from Anonymous and that contain threats of violence against the cult itself. This latest stunt is simply the next step in their campaign of demonizing Anonymous.
The problem with Anonymous is that anyone can pretend to be part of the group. While they are highly resistant to efforts by the cult to target them as individuals, they are vulnerable to false-flag tactics such as this one.
This is not the first time the cult has done this. Back in the 70's they targeted a woman for writing a book that revealed the evil nature of the cult. The cult responded by forging evidence linking her to a fake bomb threat, among other things:
http://en.wikipedia.org/wiki/Operation_Freakout
She was facing a long prison sentence until the FBI accidentally discovered that the cult had set her up while conducting another investigation
http://en.wikipedia.org/wiki/Operation_Snow_White
Scientology is evil. It is something that most people who have never dealt with the cult have a hard time understanding or believing. To describe the nature of this cult to someone who is unfamiliar with it is very difficult because polite society lacks the terms needed to accurately convey the depth of evil found within this organization. It is also difficult because an accurate description defies belief. Most people are unable to contemplate something so evil actually existing in the real world.
But scientology is that bad, and it is real. Its victims are a multitude and its crimes are horrific.
But don't take my word for it, read up on it yourself:

Re:iTunes / Amazon.com gift certificate....I was under the assumption that the VeRO program allowed companies direct access, as discussed here a little while ago. There's a paper about it here which quotes: Once membership has attached, VeRO members have available to them the VeRO Reporting Tool, which is software designed to automate the process of alleging infringements to eBay. Upon receipt of a NOCI, eBay removes the allegedly infringing listing apparently with little or no review of the validity of the complaint. and a little later: One person claimed to use VeRO to remove over 500 listings in a day. My question I guess is this - how much oversight is actually there between the automated filing of a NOCI and the takedown, or is this also automated?

Re:Isn't this against the law?
Considering that hiring a contractor is an outside case, it seems fair that the government prove that the only people ever involved in making the video were all contractors. Every single person involved in the video (I'm betting there's a nice long list of credits at the end of it) should be questioned, in court, to find if at the time they were employed by the government. I'm willing to bet in the case of something such as a video, while contractors would be involved, there would also be some government employees involved, as actors or otherwise, muddying the copyright waters. Those sections of the video involving anyone working for the government should be permitted to be stripped from the video and made public.
And, of course, this is why the DMCA is bad, since it's an act-first, ask-questions-later, law. Hopefully the affected individual will stand up for their right to a hearing by posting a counter notification, forcing the government's hand. It's not likely they will, though. -
Re:Isn't this against the law?Wouldn't the air force have to claim that they were in fact the copyright owner of this video to file a DMCA notice? Doesn't that mean YouTube or the person who posted it could actually just go ahead and file suit against the government since this is a false claim?

Because you can build a radio (albeit a lousy, AM-only one, and only if there is an AM transmitter nearby) out of dental work. There's a circuit for it that was in all of the old Radio Shack n-in-one kits. But they couldn't make it work, so they said "Busted!" Quitters. (Snopes reference: http://www.snopes.com/radiotv/tv/fillings.asp Radio circuit: http://www.ece.cmu.edu/~ee321/spring00/lab3.pdf. Getting rid of the tuning capacitor, coil, and ferrite rod just kills your gain and you can only "tune" the strongest signal. You can build a Schottky diode out of a semiconductor-to-metal junction; the tooth could provide the semiconductor, and the filling the metal. The "earphone" can be anything piezoelectric, again, the materials used. There will be some gain since the sound will be conducted via bones instead of the air.)
I digress, but my point remains: Mythbusters is lots of fun, but peer reviewed and repeatable it isn't.
And back on topic: The inventor may get the rocket over the 100 km into space, but unless he can get it up in excess of 15000 knots parallel to the ground, it's not going to be in orbit. Most of an orbital rocket's thrust isn't for gaining altitude, it's for getting orbital velocity. This is why something like SpaceShip One has a long way to go before it could achieve orbit. A satellite must throw itself at the ground and miss. -

Re:The Video That Started It & A Few Notes
Something you have to understand is that Scientologists _know_ they have the answers to everything (because L. Ron Hubbard said so). If a member has any doubts, then they're "out of ethics" and have to report for additional training (at their expense). The CoS does not use the same meaning of the word ethics that you or I would. To them, ethics is doing and believing exactly what you're told. If you don't understand something, or have questions, then you are assumed to simply not understand the material; because if you did understand the material, you wouldn't have any questions.
The organization is set up so that it slowly isolates members from normal society, both physically but also mentally. Everything the CoS teaches becomes the truth and any conflicting information is actively ignored. The group as a whole forms a sort of feedback loop whereby members receive positive affirmation from the group when they do, experience or feel something the CoS wants them to feel regardless of whether or not it's true. This is why some people claim that Scientology has helped them, it's not because of the "tech", it's because they feel acceptance and safety within that group.
The church has several ways of dealing with dissent and criticism. The first is by declaring someone a suppressive person, or SP. SPs are considered to be very, very evil people as they're trying to suppress or prevent the CoS from saving mankind (yes, that's their stated mission). People who leave the church, or people outside of the church that are trying to talk someone into leaving are "declared" SP which means that Scientologists are forbidden from speaking to them about anything meaningful. If you're a Scientologist and someone is an SP it doesn't matter whether or not they're your father, mother, brother or daughter, they're dead to you. The second way is through their "fair game" doctrine which basically states that the CoS will not punish a member for anything they do towards an SP, be it harassment, extortion, assault or murder.
David Touretzky (yes, _that_ Touretzky) has some great information about Scientology available on his homepage. There's a fantastic article available that describes exactly how someone gets sucked into the cult, little by little. Note I say cult and not religion because the CoS _is_ a cult. They simply call themselves a religion in order to attempt to shield themselves from "interference" from government and to take advantage of IRS tax breaks (so they can keep more money). In addition, they have members sign contracts that absolve the church of any responsibility should something like you dying from their Introspection Rundown happen. Check out this contract they have you sign. Pay particular attention to this sentence,
I understand, acknowledge and agree that the Introspection Rundown addresses only the individual's spiritual needs and I freely consent, without reservation, and without condition or limitation, to Church members conducting the Introspection Rundown, and that I accept and assume all known and unknown risks of injury, loss, or damage resulting from my decision to participate in the Introspection Rundown and specifically absolve all persons and entities from all liabilities of any kind, without limitation, associated with my participation or their participation in my Introspection Rundown.
Notice it says "only the individual's spiritual needs", which means that it doesn't meet your physical needs and you can die from their "ritual" like Lisa McPherson did.
I could go on and on about things like church members being locked into compounds with patrolling armed guards, related organizations like Narconon treating drug abuse problems with long saunas and megadoses of niacin or actual proved conspiracies like Operation Snow White and Operation Freakout, but I'd prefer the reader follow some of the links I provided and educate themselves.
