The SAC Double Negative Option

Howard Knopf doesn’t like The SAC Double Negative Option Celestial Jukebox, but I have to quarrel with a number of his reasons.

Many of these have to do with defending the existing media levy schemes which unfairly extract funds from people who have no intent of copying copyrighted work and who are provided no option for declaring and committing to avoiding such activity when making the purchase.
Until there is provision for specially marked exempt media, the existing levy scheme is just legalized theft and like any other manifestly unfair law it undermines public respect for the law in general.

Also particularly galling is #6 “It’s inherently socialistic” – not because I have socialist tendencies myself (though I do), but because (a) it’s not, and (b) whether it is or not has no relevance to the effectiveness of the proposed mechanism, so (c) the accusation is just presented as name-calling.

Is Mental Causation a Problem?

Stephen Downes points to this review by Sara Worley in NotreDame Philosophical Review of the book ‘Mental Causation’ by Anthony Dardis, and he (Stephen) concludes with this:
“The main takeaway? This nice neat picture of ‘A causes B’ is deeply mistaken.”

Now I’m no philosopher, and I haven’t read the book, but I have to agree with Stephen on this. It has long seemed to me that even in the purely physical world the whole idea of cause and effect is just baby-talk. i.e. superstitious nonsense that has no real meaning beyond the question “What is a minimal subset of actual antecedents of B from which the eventual occurrence of B could have been deduced? (indefinite article intended since solution not necessarily unique).”

Born on a Blue Day

Coincidentally I read ‘Born on a Blue day’ just yesterday – i.e. one day before zac at squareCircleZ posted his summary review – (having been led to the order the book after watching a video posted – also at SqCZ I think – a couple of months ago). My only difference with the review is that I would reverse what Zac says about the last quarter and the finale. (And anyone who reads any of my views about climate etc may rightly suspect that I couldn’t help having reservations about the breeding practices of Daniel’s parents – admirable though their parenting may have been.)

Lecturing – stupidest profession?

Donald Clark Plan B: Lecturing – stupidest profession?

An uninterruptable lecture is almost as much an abomination as a TV broadcast, but even a replayable recording is no better than a bad lecture – where the only response to a question is to repeat verbatim whatever was not understood.

The point of a lecture is to allow spontaneous rephrasing or elaboration to correct for misinterpretations. In the absence of that you might as well use a book or printed notes, since written information is both much easier to navigate and much quicker to take in than that which is spoken.

Mythical Myths about Sustainability

Many of these Top 10 Myths about Sustainability are mythical in the sense that they are just elementary misconceptions that don’t qualify as myths because they are not widely held by intelligent adults, but “Myth 6: Sustainability means lowering our standard of living” is an exception because it is, I think, widely believed by intelligent adults.

A Quantum Embarrassment to Scientific American

The latest Scientific American lead article Was Einstein Wrong?: A Quantum Threat to Special Relativity is an odd duck. It almost (but never quite) does a fair job of describing some quite challenging aspects of quantum mechanics and its relation to locality in special relativity, and yet manages to completely disgrace itself (and the magazine’s editors) within its first paragraph by asserting that “radio waves propagate through the air” in an argument identifying the light-cone locality of special relativity with non-existence of action-at-a-distance.

Please Don’t Change That URL!

From BBC – Radio Labs – How we make websites comes this quote:

It’s nice if URIs are human readable. It’s also nice if they’re hackable. It’s an absolute prerequisite that they’re persistent.

Don’t sacrifice persistence for the sake of prettiness or misguided SEO. URIs are your promise to the web and your users – if you change them or change their meaning you break that promise – links break, bookmarks break, citations break and your search engine juice is lost.

As long ago as 1998 and 1999 the W3C and Jakob Nielsen were giving the same advice, so this isn’t exactly breaking news. But the BBC story shows that the command is taken seriously by the creators of one of the best reputed dynamic web sites on the internet. So why do lesser entities feel the need to intermittently destroy all the value created by their employees in the form of established web presence?

David MacKay: Sustainable Energy – Without the Hot Air

In Sustainable Energy – without the hot air UK physicist David MacKay presents plausible back-of-the-envelope estimates of the scales of action needed under various strategies for reduction of global carbon fuel combustion. The numbers he uses are easily checked and his analysis can be re-run with revised parameters if needed. Only when a significant fraction of humanity is capable of actually doing both those things will we have any chance of making the right decisions.
