iMac Intel 27" Teardown: essential reading for would-be customers

Andy M has ordered his 27" Nehalem Blu-Ray and USB-3 free* iMac from (no tax) Amazon.

I'm tempted. My 10 yo has done his part, ranting to his mother about how slow the G5 is. On the other hand, I just know the Nehalem stuff will be hotter than hell, slower than expected, and buggy to boot.

The iMac Intel 27" Teardown from iFixit is helping me decide if I feel lucky. For example, the RAM is easy to upgrade, but the hard drive is untouchable. That means when the drive fails (mine have 2.5 year lifespans) the replacement will require a trip to an Apple Store.

* I suspect Blu-Ray licenses have some very evil aspects - not only on cost and complexity, but with IP and functionality implications as well. Those implications extend to the operating system

... Apple lacks software support for playing copy-protected Blu-ray movies, so if you install a Blu-ray drive, you'll have to boot into Windows to enjoy the show....

This machine is designed to take high quality video output from an copy-protected DRM compliant Blu-Ray.

More than Blu-Ray I'd love to see USB 3, but I remember the introduction of similar standards. The first versions rarely work properly, you usually need to wait a year after initial products before you get something that works. In the meanwhile the new tech displaces something that does work (like Firewire).

Update: Andy tells me the current Intel iMacs have the same hard drive configuration. I've been spoiled by the wonderfully serviceable G5 iMac.

The Dinosaurs were tougher than we thought - Shiva

We knew the dinosaurs were tough. Turns out it may have taken a hell of a lot to kill the non-Avian dinosaurs ...

Mass extinctions: I am become Death, destroyer of worlds | The Economist

... The Chicxulub crater, as it is known, may have been a mere aperitif. According to Sankar Chatterjee of Texas Tech University, the main course was served later. Dr Chatterjee has found a bigger crater—much bigger—in India. His is 500km across. The explosion that caused it may have been 100 times the size of the one that created Chicxulub. He calls it Shiva, after the Indian deity of destruction.

Dr Chatterjee presented his latest findings on Shiva to the annual meeting of the Geological Society of America in Portland, Oregon, on October 18th. He makes a compelling case, identifying an underwater mountain called Bombay High, off the coast of Mumbai, that formed right at the time of the dinosaur extinction. This mountain measures five kilometres from sea bed to peak, and is surrounded by Shiva’s crater rim. Dr Chatterjee’s analysis shows that it formed from a sudden upwelling of magma that destroyed the Earth’s crust in the area and pushed the mountain upwards in a hurry. He argues that no force other than the rebound from an impact could have produced this kind of vertical uplift so quickly. And the blow that caused it would surely have been powerful enough to smash ecosystems around the world...

... Extensive dating research at Chicxulub, however, now suggests that the object which created that crater actually struck 300,000 years earlier than the dinosaur extinction, meaning there really should be two ejecta layers. That there are not could be explained by the fact that the accumulation of sediment in most rocks is so slow that the two layers are, in effect, superimposed. Alternatively, it could be that no one has been looking for two layers, so they have not seen the double signature or have ignored its significance. Indeed, two iridium layers have been found in some places. Anjar, an Indian town north of the impact site, is one. That is leading Dr Chatterjee to suggest that the two big impacts did take place at different times.

The picture that is emerging, then, is of a strange set of coincidences. First, two of the biggest impacts in history happened within 300,000 years of each other—a geological eyeblink. Second, they coincided with one of the largest periods of vulcanicity in the past billion years. Third, one of them just happened to strike where these volcanoes were active. Or, to put it another way, what really killed the dinosaurs was a string of the most atrocious bad luck.

Dinosaurs were even tougher than we'd imagined Bayesian reasoning suggests the earth has also been more dangerous than we've thought.

Corporations rot from the top - the GM story

This does not surprise me ...

Barack Obama to order salary cuts at bailed-out firms | guardian.co.uk

... Feinberg's move against top corporate pay came as Obama's former "car tsar" attacked the "stunningly poor management" he encountered at Detroit's carmakers as he worked to avert a collapse of the biggest US auto firms this year.

Steve Rattner, a former private equity executive, was the treasury secretary Timothy Geithner's top adviser on the car industry between February and July – when the US government acted to rescue both General Motors and Chrysler.

In an article for Fortune magazine, Rattner offered a savage verdict on the leadership culture at the industrial giants, singling out GM's former boss Rick Wagoner for his "friendly arrogance", and top executives' reluctance to mix with workers.

"Everyone knew Detroit's reputation for insular, slow-moving cultures," he said. "Even by that low standard, I was shocked by the stunningly poor management we found, particularly at GM, where we encountered, among other things, perhaps the weakest finance operation any of us had ever seen in a major company."

Rattner attacked GM's top executives for sequestering themselves on the top floor of the Renaissance Centre skyscraper in Detroit, with exclusive lifts, to avoid mixing with lower-ranking "drones"...

This is to be expected since ...

1. If the management weren't fairly average GM wouldn't be in the mess it's in.
2. No exceptional person would tolerate this kind of management style, so they wouldn't take a job at GM.
3. Power is an amazing intoxicant. Only those with exceptional abilities can keep any kind of perspective while they enjoy the high. Given #1 and #2 though, we know GM executives can't have those abilities.

Corporations rot at the top. Off with their heads.

The Google branded netbook is coming in early 2010

This rumor is mostly about the Google phone, but that's not the interesting part (emphases mine) ...

There Really Might Be a Google Phone. No Seriously!

... According to Kumar, Google will embed the same iteration of Android as the one currently being used in the Motorola Droid and the device will be based on Qualcomm baseband chips. Google will also introduce its own branded netbook, again embedding Qualcomm Snapdragon, early next year...

That's Google Chromestellation, a version of this netbook will probably be sold through Verizon -- "free" with a 2 year data services contract.

Update 10/23/09: By chance I came across a post I wrote in 2004:

InfoWorld: Wal-Mart breaks price barrier with Linspire Linux laptop

Wal-Mart is offering a laptop that dives below the $500 pricepoint, and it's no accident the machine, from Linspire, runs a Linux-based operating system.

The Balance laptop, at $498, enters a mass market at a price that will undoubtedly accelerate Linux adoption.

The laptop comes with the OS, Internet suite, and Microsoft-file compatible office suite and can be used with both dial-up modems and broadband connections. The machine comes with a VIA C3, 1.0 GHz processor, 128 MB of RAM, which is expandable up to 512 MB with SODIMM (Small Outline Dual In-line Memory Modules). It includes a CD-ROM drive and a 14.1-inch LCD screen...

... The laptop's included Mozilla Internet suite comes with a fast-functioning browser and email program that can display Web-based forms, PDF documents, images, and multimedia files. The suite's included instant messenger program works with AOL, MSN and Yahoo logins.

No-one makes money on desktop machines. I recall reading that if one excluded the kickbacks Microsoft provided Dell, that they lost money on their best selling desktop machines. Laptops were different -- they still had a solid margin.

Not any more. Only Apple will be able to demand a premium for their top selling entry-level laptops, and the iBook may drop to $900 or so. Updrade this thing to 512MB and hook it up to a monitor/mouse/kb and there's a very compact and virus-free machine for my mother to use -- with gmail for her email.

*Cough*.

So five years ago I predicted that only Apple would be able to demand a premium for laptops (sort of true, but I was thinking 1 year) and that the "iBook" would drop to $900 (MacBook is now $999 - but this isn't 2005).

I think I'd better temper my Netbook optimism a wee bit.

Update 11/20/09: It's late 2010 and it won't be cheap?! Wow. I sure missed this one!

Boethius – the most important philosopher you’ve probably never heard of

The first I remember hearing of Boethius was this In Our Time programme on The Consolation of Philosophy…

In the 6th century AD, a successful and intelligent Roman politician called Boethius found himself unjustly accused of treason. Trapped in his prison cell, awaiting a brutal execution, he found solace in philosophical ideas - about the true nature of reality, about injustice and evil and the meaning of living a moral life. His thoughts did not save him from death, but his ideas lived on because he wrote them into a book. He called it The Consolation of Philosophy…

Boethius, I learned, was a Christian influenced neo-Platonist scholar and man of the world who lived in the waning years of the Roman empire. Wikipedia has more …

Anicius Manlius Severinus Boëthius^[1] (ca. 480–524 or 525) … was born in Rome to an ancient and important family which included emperors Petronius Maximus and Olybrius and many consuls. His father, Flavius Manlius Boethius, was consul in 487 after Odoacer deposed the last Western Roman Emperor. Boethius himself was consul in 510 in the kingdom of the Ostrogoths. In 522 he saw his two sons become consuls. Boethius was executed by King Theodoric the Great…

It is unknown where Boethius received his formidable education in Greek. Historical documents are ambiguous on the subject, but Boethius may have studied in Athens, and perhaps Alexandria…

As a result of his education and experience, Boethius entered the service of Theodoric the Great, who in 506 had written him a graceful and complimentary letter about his studies…

…By 520, at the age of about forty, Boethius had risen to the position of magister officiorum, the head of all the government and court services…

… Boethius's best known work is the Consolation of Philosophy, which he wrote most likely while in exile under house arrest or in prison while awaiting his execution, but his lifelong project was a deliberate attempt to preserve ancient classical knowledge, particularly philosophy. He intended to translate all the works of Aristotle and Plato from the original Greek into Latin…

…it is his final work, the Consolation of Philosophy, that assured his legacy… the work was translated into Old English by King Alfred, and into later English byChaucer and Queen Elizabeth; many manuscripts survive and it was extensively edited, translated and printed throughout Europe from the 14th century onwards.^[5] Many commentaries on it were compiled and it has been one of the most influential books in European culture…

From our perspective it’s not clear how Christian Boethius was by the time he died, but he’s a Catholic saint anyway, and supposedly a favorite of Benedict. He was immensely influential in many ways, but I suspect most of us have never come across his name.

I do like In Our Time, it’s so sad that the BBC doesn’t sell past programmes on iTunes. (You can subscribe easily to the podcasts, but you can’t turn the available streaming archives into mp3/aac unless you’re a serious geek.)

Update 11/5/09: When I listen to the best of IOT I take it in sips. A bit of listening, a bit of contemplation. The very best I'll do twice. Since I first wrote this I'm about three quarters done with the Consolation of Philosophy, and it is among the best. Great guests, and for once Melvyn didn't run out of time. They fit Boethius into the chain from the Stoics through Schopenhauer to Camus and Nietzsche (but not Hume and they didn't trace back to the Greek religious tradition of the futile but heroic response to inevitable tragedy).

I'm going to have to go back to past discussions of the Stoics, and I'm looking forward to the new episode on Schopenhauer.

An abundance of earth-class planets

We're filling in a key variable in the Drake equation. Smaller rocky planets are now believed to be common ...

BBC NEWS | Science & Environment | Scientists announce planet bounty

... The 32 "exoplanets" ranged in size from five times the mass of Earth to 5-10 times the mass of Jupiter, the researchers said.

They were found using a very sensitive instrument on a 3.6m telescope at the European Southern Observatory's La Silla facility in Chile.

The discovery is exciting because it suggests that low-mass planets could be numerous in our galaxy.

"From [our] results, we know now that at least 40% of solar-type stars have low-mass planets. This is really important because it means that low-mass planets are everywhere, basically," explained Stephane Udry from Geneva University, Switzerland.

"What's very interesting is that models are predicting them, and we are finding them; and furthermore the models are predicting even more lower-mass planets like the Earth."...

This is consistent with the fun calculation I ran 8 months ago, the one predicting several hundred technological civilizations operating in the galaxy at this "moment".

The data continues to point to a "go no more a wanderin" solution to the Fermi paradox.

Snowe has defenders in Maine

I don't know how strong Snowe's home base is, but this physician executive editorial seems encouraging ...

Snowe’s chutzpa needed to reform U.S. health care - Bangor Daily News

... when the hounds come looking for Sen. Snowe’s hide, they should find us circled around her, protecting the black mane of Maine’s senior senator. We should tell them we are doing so not because we always agree with her, or because we think the Senate’s health reform bill is everything we want, but because last Tuesday she stood up for us and to us and did the tough thing, the right thing, and we are now doing the same for her.

The triumph of the Yes Men – Chamber of Commerce endorses climate change legislation

The YES MEN have triumphed …

The Chamber of Commerce hoax was perpetrated by the Yes Men, in tandem with a group of activists known as the Avaaz Action Factory.

Yes Man Andy Bichlbaum showed up at the 11am press conference that had earlier been announced by a "Chamber of Commerce" press release, and, impersonating a Chamber executive, declared:

We at the Chamber have tried to keep climate science from interfering with business. But without a stable climate, there will be no business.

At some point, reports Mother Jones, an actual Chamber spokesman showed up and yelled: "This is fraudulent!"…

Reuters fell for it, and the NY Times picked it up …

Reuters is now admitting that their epic screw-up today — it fell for a hoax press release and ran a story about the U.S. Chamber of Commerce supposedly changing its opposition to climate change legislation — could actually have moved financial markets…

… The Reuters story was picked up by the New York Times and the Washington Post and rocketed around the political world today.

In case you missed it, Reuters ran a story today claiming the Chamber’s shift, basing it on a fradulent press release claiming the Chamber “is throwing its weight behind strong climate legislation.”…

We’re all hoping the Chamber of Commerce will try to sue the YES MEN. If they do, the YES MEN’s coffers will swell …

Why I dropped the Freakonomics blog

I didn’t drop the Freakonomics blog (Levitt and Dubner) just because of their anti-rational climate change ploy.

I admit, the thorough evisceration by (via DeLong) Last Post on Superfreakonomics, SuperFreakonomics- Global Cooling, Superfreakonomics on climate, RealClimate- Why Levitt and Dubner like geo-engineering, Does -Superfreakonomics- Need A Do-Over and so many others did take a toll.

In the end though, it took a lethal blow from CT to do them in. There’s a world of difference between original thought and faux contrarianism. As fun as Levitt and Dubner have sometimes been, they’ve hit the media bottle too many times. They can no longer distinguish between skeptical thinking and the intellectual vice of fashionable thought.

Velikovsky was a contrarian. I doubt Levitt and Dubner aspired to his company, but that’s where they’ve ended up.

Not to worry though, I’m sure their book earnings will ease the pain of my departure.

Obama and the Laser – stop the stupidity.

Alan Blinder likes Obama’s economic accomplishments, but he concludes they’d be better if (emphases mine) …

… Mr. Obama’s accomplishments in just nine months are palpable and were very much needed. If he seems to have achieved little, it’s partly because he set out to do too much. Too bad he didn’t just “focus like a laser beam on the economy.”

I read the same thing from pundits wishing Obama had been a “laser beam” on Health Care, or Climate Change, or American honor, or Afghanistan (I’m sure there are other recommended targets, but you get the idea).

I know Americans have a memory of about 3 weeks, but this is the so-called punditocracy we’re talking about. Pundits are supposed to have a memory of at least 3 months.

Ok, I see the problem.

Well, for the sake of ventilation, if for no other benefit, let me put this plainly.

Bush, Cheney, Greenspan and the GOP just about trashed America and pushed the world to the edge. They were blunderers at a moment in American history where blundering was particularly dangerous.

Obama inherited a nation in critical care. We’re still there. It’s going to take 10 years to crawl out into a changed world. We aren’t going back to the 1990s, because that path is gone.

Obama can’t “focus like a laser beam”. He’s got to deploy his team on a wide front – holding in some places (economy), strategically retreating in others (climate), pressing the advantage in a few (health care). Obama is not Putin – he has to respond to the chaotic fluctuations of the political environment.

Stuff the laser beams.

The NYT does not like the Taliban

The NYT has recently published at least 3 articles that deliver pretty much the same message …

• Pakistan Attacks Show Tighter Militant Links
• Remembering Afghanistan’s Golden Age (1964 to 1974)*
• Held by the Taliban - A Times Reporter’s Account. A Five-Part Series by David Rohde

The message is that the modern Taliban have become inextricably linked to al Qaeda and Pakistan. There’s a less clear attempt to argue that Afghanistan is not a hopeless case.

I remember a similar NYT consensus in the build up to the invasion of Iraq, when the NYT jumped on the WMB and especially bioweapon bandwagon. In retrospect the Times was being played by their sources.

That’s not to say this consensus is wrong, but we’d be foolish to forget how this game is played.

I’m very glad Obama is doing his strategic review.

* My recollection is that in the early 80s Afghanistan was a poster child for impending ecological collapse. It’s a very fragile ecosystem, and the rapid development of the 1970s combined with severe oppression of women had led to extreme population growth and environmental degradation. Climate variation may have also played a role. By the late 1980s and early 1990s Afghanistan was in economic and ecological collapse.

Unfortunately, I can’t find any references that agree with my memory!

This is important. If the Afghan agricultural infrastructure is gone, then it has a very long road ahead.

Simultaneous infections with multiple viruses - why are there so few studies?

For the past several years I’ve wondered about the clinical presentation of patients with multiple simultaneous infections.

The H1N1 outbreaks has brought this to mind again. We assume bad outcomes are the result of some odd combination of immune system and viral mutation, but what about the impacts of co-infection?

I’ve asked academic physicians about this question. I usually get a started look, then a statement that “common wisdom” is that the enhanced immune response to one infection makes a co-infection less likely*.

Turns out, though, that this question was researched 21 years ago ...

Am J Dis Child -- Abstract: Simultaneous Infection With Respiratory Syncytial Virus and Other Respiratory Pathogens, August 1988, Tristram et al. 142 (8): 834

… The presentation and subsequent course of respiratory syncytial virus (RSV) bronchiolitis may be atypical and unusually severe when simultaneous infection due to other pathogenic agents is present. During the past two years, nine of the 189 pediatric patients hospitalized with documented RSV infection were found to have the following simultaneous isolates from initial respiratory tract specimens: four adenovirus, four pneumococcus, one cytomegalovirus, and one Pneumocystis carinii. Noted complications attributable to the second pathogen included thrombocytopenia and anemia (cytomegalovirus), hepatitis and disseminated intravascular coagulation (adenovirus), and sepsis and osteomyelitis (pneumococcus). Three of the four patients with RSV and adenovirus died of severe respiratory failure despite mechanical ventilation; two of these patients received ribavirin therapy…

So 21 years ago it was shown that children with co-occurrent viral infections, such as adenovirus and RSV, could have more severe disease progression.

You’d think this study would have been widely cited, but you’d be wrong. A pubmed search on “simultaneous infection virus” returned no strong hits.

I’d love for someone who knows this area to explain why this hasn’t been studied further.

See also: Defining a disease: how often are atypical presentations due to multiple agents? (Feb 2006)

* When smart people say this they immediately get a worried look. In medicine “conventional wisdom” is often shorthand for “something that got into textbooks in the 1960s but, really, on inspection, has never been studied”.

Update 11/1/09: If one viral infection really prevented another, one could manage dangerous epidemics by giving everyone a cold.

The paradoxical power of the Snowe effect

In an ideal world, smart, rational Republicans would balance the worst instincts of my team.

These mythical Republicans would know that government has its own flaws, that my team’s backers can be misled by self-interest and constituency politics. They’d remind us that markets can solve optimization problems better than any planner.

Unfortunately, in this world, the GOP is the Party of Torture, Cheney, Palin, Beck and Limbaugh.

Except … for two senators from Maine – Susan Collins and Olympia Snowe.

Chance, and the complete abdication of the Party of Beck, has made Olympia Snowe immensely powerful in this particular debate. She has the same impact as would, in better times, 20 sane GOP senators …

Why One Vote Matters in the Senate - Room for Debate Blog - NYTimes.com

… The country, frankly, is fortunate that the one holding the most cards is Olympia Snowe. Few public officials are as honest, principled, independent and smart as she is. The bargains she is striking to enable a bill to pass are almost all aimed at improving the quality of the health reform bill and helping more people to get health insurance coverage and health care. It may be unfortunate that one person, representing a tiny sliver of Americans, has so much power. We could do a lot worse…

Snowe is best known, to my team, as the enemy of the public option that’s favored by two of our top leaders – Reich and Krugman. 

Maybe that’s not all bad. I could believe that while the public option might be a very good theoretical idea, it might also be politically disastrous. Maybe we need to find a 2nd best option, knowing that we’re going to have to revisit health care reform many times in the decades to come.

It’s a sad day for America that the GOP is shattered, but, at least for the moment, we have a reasonable proxy to the mythical GOP we never had. Maine, you rate.

When it's as good as it gets

A lot of the comments on this post of Judith Warner's post imply she's melodramatic...

I Feel It Coming Together - Judith Warner Blog - NYTimes.com

... This is the cruelty of middle age, I find: just when things have gotten good — really, really, consistently good — I have become aware that they will end...

... I now see the passage of time more as a kind of bell curve. Years of ascension, soaring anticipation, followed by a plateau — which is not so bad, really — and then, no way to sugar coat this: a rather precipitous decline.

You are not supposed to think this, much less say it. A decline? Never!

Fifty is the new 30, after all; and 70 is the new 15, and 40 — well, the forties are just so fabulous that they can’t even be considered middle age. Even if they do happen to fall right smack in the middle of what, despite our best efforts, is still a limited human lifespan.

Susan Jacoby, the author of “The Age of American Unreason,” among other books, found herself, a year or so ago, attending a panel at the World Science Festival in New York City called “Ninety is the new Fifty,” and is now writing a book on the “delusion” she says we all have “that age is something that can be defied.”...

Ok, maybe a bit melodramatic - but not entirely. I'm six years older than Ms Warner, and I'm sympathetic.

Yes, there are those who might remember that I felt the pressure of mortality at 5, 10, 15, 20, 25, 30, 35, 40, and so on.

Well, in retrospect, I was damned right every time. Sure, there have been 80 year olds exploring Kashmir -- but there are more 80 year olds that Nature's tortured with a rigor that Dick Cheney might envy. Not to mention the quieter cohort.

My life is good, in many ways the best it's been. Even so, we all have a right to complain. Mortality sucks, 92* years is not nearly enough.

I'm with you Judith! I'll take my mortal life, but I reserve the right to bitch.

* My current projection - but it's not a promise and if we don't get an Alzheimer's breakthrough soon I'd discount the last 10.
