Living Room / Re: Interesting article on homeopathy - from a medical perspective
« Last post by nontroppo on November 27, 2007, 05:26 PM »
"There are some aspects of quackery that are harmless - childish even - and there are some that are very serious indeed."
nontroppo -
imagine if someone said something like that about your career for example or something you believe in?

Yes I suppose I would have replaced the word "quack"[1] with "mysticism" if I was him. But as a scientist, I engage with criticism and welcome it, even if it is a post-modernist telling me science is nothing more than a social construction and pure human fantasy ;-) The majority of the post was gentle and I'd hope those serious about homeopathy would not just stop reading at the first sentence.

[1] Though as homeopathy can show no significant medical efficacy above placebo, to continue convincing people it works better than placebo (and taking their money for it, homeopathy ain't cheap) is debatably closer to quack than mystic...

Theory: A theory is more like a scientific law than a hypothesis. A theory is an explanation of a set of related observations or events based upon proven hypotheses and verified multiple times by detached groups of researchers. One scientist cannot create a theory; he can only create a hypothesis. ...both a scientific theory and a scientific law are accepted to be true by the scientific community as a whole. Both are used to make predictions of events. Both are used to advance technology.

Judging by what he's saying, he is reacting against, well, lots.
But unfortunately reacting is a key word.

I don't see this as a reactionary piece at all. Most of the article constructively talks about evidence-based medicine and the basic mechanics of the scientific method. The first couple of paragraphs and the last probably contain what you feel is offensive.

And there is the rub. Because Winterson tries to tell us - like every other homeopathy fan - that for some mystical reason, which is never made entirely clear, the healing powers of homeopathic pills are special, and so their benefits cannot be tested like every other pill

This may seem offensive, but it is merely accurate. Homeopathy is based on mysticism. If one is offended by that I'd imagine it is because one feels mysticism is negatively construed. Ben makes it very clear that that mysticism is valuable, and makes the placebo effect stronger. But when one takes the mysticism and pushes it into the realm of life-threatening ailments, adds misleading use of the scientific method, and makes un-validated claims as if they were as factual as anything else, there is valid cause for concern.

His first paragraph, aimed squarely at Jeanette Winterson, *was* pretty caustic. But rightly so, she is craftily evasive as only a Politician could be on HIV (dismissive of HIV virus revisionists then wooly over what she believes the clinic she sent her fee for the article actually does), and her silly use of pseudo-science jargon words was rightly critiqued, it was deliberate word abuse to sound convincing.

The "dialog" between his fictional homeopathy fan and critic is pretty sympathetic to the fan:

So let's imagine that we are talking to a fan of homeopathy, one who is both intelligent and reflective. "Look," they begin, "all I know is that I feel better when I take a homeopathic pill." OK, you reply. We absolutely accept that. Nobody can take that away from the homeopathy fan.

It is not however sympathetic to the evasive defense of homeopathy, because the scientific method cannot be sympathetic. He is not emotionally blasting homeopathy, but giving a clear trail of empirical data for the majority of the article as to why we cannot deal with homeopathy using a method which has given us so much.

But when they're suing people instead of arguing with them, telling people not to take their medical treatments, killing patients, running conferences on HIV fantasies, undermining the public's understanding of evidence and, crucially, showing absolutely no sign of ever being able to engage in a sensible conversation about the perfectly simple ethical and cultural problems that their practice faces, I think: these people are just morons. I can't help that: I'm human.

Note where the "moron" is being directed to. It is *not* aimed at all homeopaths, but those who have been obstructive, deceptive and antagonistic. There have been recorded cases where the malarial advice they gave has resulted in deaths, and their regulatory body has failed an investigation -- this is important stuff! He also gives the clear suffix that naming those obstructive homeopaths morons is his emotional response to such behavior.

To reiterate: IMO the vast majority of the article is constructive, and not some emotional tirade aimed at hurting people. His first paragraph is specifically dismissive of Wintertons article (not all homeopaths), and his last paragraph is clearly framed as an emotional response to those homeopaths who have exhibited despicable behaviour.

« Last post by nontroppo on November 26, 2007, 04:50 PM »
How does Linux or OS X handle configuration stuff?

OS X has something called .plists - they reside in:

/System/Library/Preferences/ - core OS, no playing there José!
/Library/Preferences/ - prefs for all users
~/Library/Preferences/ - prefs for particular user


plists are XML, and can be encoded as a binary format for faster execution if needed. They use a simple namespace mechanism for naming to avoid collisions (e.g. com.apple.dock.plist for Apple's dock preferences). By dragging your user preferences directory around, you can easily migrate your settings (it worked amazingly well on my upgrade to Leopard). The OS provides users with a way to query and edit plists via the commandline or applescript:

defaults write com.apple.dock mouse-over-hilte-stack -boolean YES

There is also a GUI editor which represents them as a DOM. Nothing OS critical is stored in the user accesible plists. You can nuke prefs directories and everything will work fine from internally stored defaults IIUC. Cross-platform apps like Firefox and Opera store prefs in subdirectories, and they use whatever formats they want (Opera still uses its custom INI format on OS X for example).

Registry = Fear and Loathing in HKEY_LOCAL_MACHINE...

Humans suck. But some things are just not really open for discussion. Abortion is murder or not, depending on what metaphysics sits at you core. Discussing abortion is futile for that reason. Homeopathy makes claims to scientific verification, but really sits as a belief system and thus debates about it cannot function as they may do for plate tectonics or aviation engineering.

I really wouldn't take advertising any more seriously than I take celebrity gossip; all froth, no coffee. If we were to see the world through the lens of the advertisers, it would be worse than taking too much mescaline at a Las Vegas Casino. My classic observation: girls shaving their shiny long legs for ladies shavers have fully shaved legs already. WTF? Advertisers can't show the product "working", as it would show the perceived imperfection the product aims to eradicate. Smoke, mirrors, superficiality.

I think I hate it because it reminds me of high school. The "cool" guys making fun of the "geeks."

Or you can see it as the business class against normal users, depends on your cultural stereotypes. But this is just classic advertsing psychology, not specific to Apple.

I think the "Don'tgive up on vista" campaign is pretty funny though (turn brain off first though), and great advertising for XP....  ;)

...and I haven't gotten into the habit of content searching...

Suppose it depends on what you do with your work, but content (and metadata) searching is the biggest thing since sliced bread for me, a genuine certified revolution in computer-nontroppo interactivity. That's why I'm curious about Vista's search capabilities. I checked the Ars Technica review but it skimmed over the details and I've yet to find a comprehensive resource.

Anyway, be sure to grab a 64-bit version of XP when you're going back, unless you have stuff with 64-bit problems.

Have things got better in the last 8 months or so? A colleague of mine custom built a high-end rig specifically for 64bit XP (hardware was supposed to be compatible), but it was a nightmare so he reverted to 32bit.

Which is kind of unfortunate really, cause if he has a worthwhile message it would be nice if it was presented in such a way as to be readable by the "other" camp...
And if your friends are converted from homeopathy? maybe they'll find something better..

Maybe they will. I think Ben, though passionate, wrote as balanced an article as he could; there are deeply disturbing trends that are being sponsored at the highest level of homeopathy at the moment (SoH's ignoring their members prescribing anti-malarial remedies, treatments for AIDS). Reports claiming efficacy are no more than consumer surveys, and facts are misrepresented. That the SoH refused to even bother investigating their members for the anti-malarial prescriptions, and instead paid lawyers to chase bloggers speaks of how, at least the main body of homeopaths here, does business. This is not only innocuous.

Living Room / Re: Mac OS X Leopard - All show and no go, or is it worth a try?
« Last post by nontroppo on November 22, 2007, 04:51 PM »
Oh, and my conclusion on whether Leopard is worth a try: a big fat juicy *yes*.

Upgrade was amazingly fast, it kept all my settings intact but did a clean excision of the old OS. Leopard is "faster" from a UI perspective, it's difficult to describe but it just flows (graphics pipeline was optimized IINM). Memory consumption and CPU are equivalent to Tiger (I haven't enabled Time Machine yet though; iTunes is actually much better under Leopard than Tiger). Quicklook rocks, but really it does! Spaces is spartan, but the essentials work great. What is really good is exposé and spaces can work together, showing all open windows in all desktops. But the best things about Leopard are really the smaller fixes, including some of the glaring holes (i.e. being able to share single folders without using third-party accesories).

I also helped install it on an old 867mhz ibook, upgrading from Panther. We did a clean install, and without any tweaking, once spotlight finishes its initial indexing, it works great. Leopard seems to scale its graphics according to available hardware, though you can't really tell (bits are less translucent), the UI stays "fast". Quicklook is a little less quick, but not by much.

Actually, by looking through Gutmann's slides (80 pages worth!), which are an update of his early report:

http://www.cypherpun....to/~peter/vista.pdf

It looks as if Vista's DRM is slowly unravelling in several aspects, as well as an ever increasing list of HDCP workarounds. There are some fascinating tidbits there on the new set of security backdoors to the Vista kernel due to the signed driver model in x64 too.

Did anyone read about tilt bits? Just amazing. Gutmann shows how hardware vendors are basically faking their way around them to keep Vista happy.

As Gutmann says:

“We were only following orders” has historically worked rather poorly as an excuse, and it doesn't work too well here either. This is just an example of the Dank defence. The Dank defence, as reported by former Assistant U.S. Attorney Andrew Grosso, was used by someone who was picked up carrying a shotgun in a park at night. With six previous violent crime convictions on his record, he explained his presence in the park by saying that a man called “Dank” had held a gun to his head and forced him to carry the shotgun. When the police turned up, “Dank ” ran away, leaving him holding the bag (or at least the shotgun). As the Assistant U.S. Attorney put it, “the jurors chose not to believe the defendant's story”. In Vista's case, we're being asked to believe that Hollywood is holding a gun to Microsoft's head and forcing them to cripple their flagship product and inflict all manner of pain on their business partners and customers, and Microsoft has no choice but to comply.

I choose not to believe the defendant's story.

If no software vendor implemented HDCP, another standard that didn't impose such radical changes would take its place.

Edit: And now the burden to comply for *nix and OSX is much higher as they will be forced into the feature parity game.

Unnecessary CPU Resource Consumption
“Since [encryption] uses CPU cycles, an OEM may have to bump the speed grade on the CPU to maintain equivalent multimedia performance. This cost is passed on to purchasers of multimedia PCs” — ATI.

In order to prevent tampering with in-system communications, all communication flows have to be encrypted and/or authenticated. For example content sent to video devices has to be encrypted with AES-128. This requirement for cryptography extends beyond basic content encryption to encompass not just data flowing over various buses but also command and control data flowing between software components. For example communications between user-mode and kernel-mode components are authenticated with OMAC message authentication-code tags, at considerable cost to both ends of the connection
In order to prevent active attacks, device drivers are required to poll the underlying hardware every 30ms for digital outputs and every 150 ms for analog ones to ensure that everything appears kosher. This means that even with nothing else happening in the system, a mass of assorted drivers has to wake up thirty times a second just to ensure that… nothing continues to happen (commenting on this mechanism, Leo Laporte in his Security Now podcast with Steve Gibson calls Vista “an operating system that is insanely paranoid”)
An indication of the level of complexity added to the software can be seen by looking at a block diagram of Vista's Media Interoperability Gateway (MIG). Of the eleven components that make up the MIG, only two (the audio and video decoders) are actually used to render content. The remaining nine are used to apply content-protection measures.

http://www.cs.auckla...pubs/vista_cost.html

DRM is not a service, it is a fundamental rearchitecture of interprocess communication in a PC, from the drivers that have had to be recoded to be Vista-compatible to the motherboard and peripheral hardware.

You can follow along with comments at Ben's personal blog:

http://www.badscienc.../11/a-kind-of-magic/

His blog is very much worth subscribing to.

As someone who has very close friends who believe in homeopathy, I find it an incredibly delicate area to engage in. I think, as Ben has eloquently expressed, that placebo is useful, complex and multi-dimensional. Homeopathy is no better than placebo in well controlled studies, but that still means that it is an effective remedy for minor ailments. By trying to pull the sheet away from the magic of homeopathy, I'm possibly removing a remedy that will work for my friends. I can try to replace that with another placebo, but placebo works fndamentally on misinformation, so why replace one dishonesty with another. So I never engage in conversations over homeopathy with my friends, unless they were going to try to use it for major illness.

Then you have chosen (or rather, it has been chosen for you): you're running a 64bit OS. A 32bit OS won't run 64bit apps - the 32bit binary from the fatexe will be chosen.

That said, I heard something about the 64bit version of OS X being somewhat peculiar.

Yes, the details have been obfuscated from the user, he/she just runs an app and if the platform supports it it will be 64bit.

As for being peculiar, in Tiger the core OS was 64bit, but the frameworks were not, so only specialised code could run and a seperate process was needed for a UI. Now, everything except for the old carbon compatibility UI layer (from system 8 days) is 64bit. This means some apps that still use that will have to  transition away from it to enable transparent 64bit OS support.

Actually it doesn't help wrt. 64bit portability - sure fat binaries are very smart, but it's still the programmer's job to, in source code, make sure his code compiles cleanly for both 32- and 64-bit modes. I'm not sure if xcode automatically compiles for each platform, or if you have to specify which platforms your fatexe should build for, but I can assure you that 32/64bit portable code doesn't happen by magic, you do need to design properly.

Oh, I agree. My point was that the potential 64bit user base is now every Leopard Mac that has a 64bit PowerPC or Intel chip, as a percentage of the total userbase that is going to be significant[1] (what is the proportion of 32bit to 64bit vista installs?). That gives a Mac developer incentive to do the grunt work to make his code portable, because in theory anyone with a newer mac and Leopard will benefit.

----
[1] A number of mac developers have suggested their next versions will be Leopard only because of the benefits Developers gain coding for Leopard. Most of their users feedback has been positive AFAICT, they have a high rate of new OS adopters.

No magic, just a bit of convenience  ;) In general, I simply like the fact that i don't have to choose a 32bit or 64bit OS, I just have an OS that runs 32bit code and will run 64bit apps as they come out. This i hope will lower the barrier to developers ensuring 64bit portability, because everyone will be able to run them without reinstalling their OS.

If you are fat-phobic, there are apps on OS X that will put your apps on a diet, liposucking the platforms not needed out  :)
