Walter Mossberg is fed up with Windows XP, he prefers OS X

Personal Technology -- Personal Technology from The Wall Street Journal.

Meanwhile, the company's historic rival, Apple Computer, has been making giant strides in ease of use. The Macintosh, with its OS X operating system, is rock solid. It is elegant, and -- when you do a feature-by-feature price comparison with Windows competitors -- it's surprisingly affordable.

The Mac is also packed with extras that Windows lacks. It has a suite of easy, free, multimedia programs that can't be matched on Windows at any price. It has a better free browser and e-mail program than Windows. It can read and create PDF files without requiring the purchase of any extra software.

Apple upgrades its operating system far more often than Microsoft does. The company's new iMac G5 model is the single best desktop computer I have ever reviewed. And Apple is the only computer company whose business is focused on consumers and small businesses.

Best of all, the current Mac operating system has never been attacked by a successful virus, and almost no spyware can run on it. This is largely because the Mac's small market share presents an unattractive target for digital criminals. But it's partly because the Mac operating system is harder to penetrate. I'm sure there will eventually be viruses that afflict Mac users, but nowhere near the 5,000 new Windows viruses that appeared in just the first six months of this year.

In terms of ease of use, Apple has opened a greater lead over Microsoft than at any time since the late 1980s, when the Mac was pioneering the graphical user interface and Microsoft users were stuck with crude, early versions of Windows.

Interesting. Mossberg is very powerful in the PC world, his WSJ column is widely read. This week he rips into Microsoft, claiming that XP and IE's security issues have made XP a step backwards from Windows 98. Instead he favors Apple. I think he overstates the stability of OS X however -- Apple has a lot of work to do with their QA process for patch releases.

Rat brain flies plane -- organic neural network

William Gibson

Florida scientists have grown a brain in a petri dish and taught it to fly a fighter plane.

The "brain", grown from 25,000 neural cells extracted from a single rat embryo, has been taught to fly an F-22 jet simulator by scientists at the University of Florida. It was taught to control the flight path, even in mock hurricane-strength winds...

When I was a youngster at CIT, one of my profs, a Dr. Hudspeth, was keen on neural networks. Back then those were arrays of silicon. Later neural networks were emulated in software. Now we build them from ... neural networks.

Gibson's blog post on this piece is a mini-snapshot of the near future.

A few months ago I posted on another use of rat brains, that time more of an intact structure. Or maybe it was a fly's neural network. Heck, I can't keep track any more.

I feel the dank chill of the nearing Singularity ...

God created the parathyroid to challenge our faith

BBC NEWS | Health | Gill theory of human glands

The human parathyroid glands, which regulate the level of calcium in the blood, probably evolved from the gills of fish, say researchers. ...

... The researchers supported their theory by carrying out experiments comparing the parathyroid gland of chickens and mice and the gills of zebrafish and dogfish.

They found both develop from the same type of tissue in the embryo, called the pharyngeal pouch endoderm.

Both structures also express a gene called Gcm-2, which is crucial for their proper development.

The researchers also found a gene for parathyroid hormone in fish, and they discovered that this gene is expressed in the gills.

Professor Graham said: 'The parathyroid gland and the gills of fish are related structures and likely share a common evolutionary history.

'This new research suggests that in fact, our gills are still sitting in our throats - disguised as our parathyroid glands.'

Can't be evolution in action. Must be a ploy by God to detect those of weak faith.

Sequencing dinosaur DNA -- the jungle fowl

BBC NEWS | Science/Nature | Chicken gives up genetic secrets

Scientists have published a detailed analysis of the chicken genome, the biochemical "code" in the bird's cells that makes the animal what it is.

... The primary subject for the study was the red jungle fowl (Gallus gallus), the wild species from which domestic poultry was bred several thousand years ago.

... There are about 1.1 billion base-pairs in the chicken genome wound into 40 distinct bundles, or chromosomes. Written in the DNA are roughly 20-23,000 genes ... In the human genome, there are 3 billion base-pairs and 20-25,000 genes ...

... The analysis reveals that just 2.5% of the human code can be matched to chicken DNA.

It is an important finding. This small portion contains genes that have been largely preserved over the 310 million years since humans and birds shared a common ancestor.

... On a pure research level, though, there are some real gems in the chicken genome.

These include the realisation that the birds have a keen sense of smell. Scientists can also see genes related specifically to feathers, claws and scales - code sequences that are absent in humans.

Yes, scales. As in dinosaur scales. Keen sense of smell -- like dinosaurs. It will be interesting to compare these sequences to other legacies of the dinosaur era. Although humans have more base-pairs, the number of genes between bird and man are remarkably similar. Does this mean we are of roughly equal complexity? I wonder how much of the DNAis apparently non-coding? There's going to be a heck of a lot of fascinating science coming from this ...

How to talk usefully about the funding of public education

A call to action for Twin Cities schools

The time has come for the state of Minnesota to put up the money needed to fund public education adequately or let school districts raise the money they need themselves, a group of Twin Cities-area school district officials said Tuesday.

The Association of Metropolitan School Districts estimates that its 26 member districts face more than $88 million in cuts in 2005-06, unless state funding formulas dramatically increase. That gloomy picture is just part of a trend, the group's leaders said at a St. Paul news conference. Over the past three years, member districts -- which educate about one-third of the state's schoolchildren -- have eliminated the jobs of more than 2,800 employees, including about 2,000 teachers.

Of all the sterile discussions I have to endure, among the least valuable are discussions about educational funding. In my experience, no-one presents any useful data.

I'd like each presentation to begin with 4 charts, with an optional 5th chart for discussions of local funding (all inflation adjusted of course):

1. A 15 yr chart of per student funding.
2. A 15 yr chart of spend on infrastructure (buildings, etc).
3. A 15 yr chart of the average salary of a state legislator.
4. A 15 yr chart of the % of students enrolled in public education (vs. private education).
5. Optional: A 15 yr chart of local tax revenue.

Once those charts are up front, one can talk intelligently. I would expect student per student costs to rise faster than inflation because:

1. Knowledge workers are becoming more costly, so there's increasing competition for teachers.
2. We're working harder to educate chidlren with language, cognitive and income disadvantages.
3. Regulations and computerization are impacting infrastructure spend.
4. Migration to private schools or to wealthier districts increases public school educational costs (private schools "cherry pick" children who are less costly to educate).

If one finds that educational spend is barely tracking inflation, then we likely have a serious underspend.

Ahh, but what if tax revenues are declining? Our population is aging and may consider education to be a lower priority. That is the crux of the matter. It is fundamentally the same issue we face with social security "reform". What is the duty owed by society to citizens, and citizens to society?

Soviet america. Four years ago, I wouldn't have given this much credence ...

Salon.com News | Whitewashing torture?

Col. C. Tsai, a military doctor who examined Ford in Germany and found nothing wrong with him, told a film crew for Spiegel Television that he was 'not surprised' at Ford's diagnosis. Tsai told Spiegel that he had treated 'three or four' other U.S. soldiers from Iraq that were also sent to Landstuhl for psychological evaluations or 'combat stress counseling' after they reported incidents of detainee abuse or other wrongdoing by American soldiers.

Artiga and other higher-ups in the 223rd M.I. Battalion deny Ford's charges. But in the aftermath of the Abu Ghraib scandal, federal agencies including the Department of Defense, the Army's Criminal Investigation Command (CID), and the FBI are finally looking into them. The Department of the Army's Office of the Inspector General has launched an investigation, according to Ford and his attorney, Kevin Healy, who have been contacted by investigators. If Ford's allegations are proven, the Army would be faced with evidence that its prisoner abuse problem is even more widespread than previously acknowledged -- and that some of its own officers not only turned a blind eye to abuses but actively participated in covering them up...

...The propellers of the huge turboprop engines on the C-130 sent scorching blasts of superheated air back toward the group, almost hot enough to singe the skin on a face. (When I left Iraq from the same tarmac a few months later, I did get burned from the blasts.) As Ford's gurney sank into the steaming tarmac, Madera and the other medical officer wheeled him up the long ramp and into the aircraft's cavernous interior. Once they were airborne, Madera unstrapped Ford and motioned for him to sit next to her on one of the hard benches that run along the sides of the plane. "She told me that she was forced to get me out of Iraq ASAP by Ryan and Artiga, who she claimed were scared to death by what I might say. She also told me that she wanted me to get out of Iraq as soon as possible because she feared for my safety." Ford said Madera also told him, "These people are serious and very scary." She apologized for having orchestrated such an exit, but said there was no other way. "I told her that I understood, but felt as though I had just been kidnapped." According to Ford, Madera replied, "You were."

Madera did not respond to several requests to be interviewed for this story.

Four years ago I'd not have given this much credence. Now I'd give it a 50% chance of being at least partially true. Indeed, one wonders if straightforward murder isn't more often used to silence critics. It would be much tougher to track down.

I wonder if any mainstream media will pick this up. There are enough names provided in this article that if there's any truth to the allegations we should learn more fairly easily.

Fake psychiatric "diagnoses" and psychiatric "sentencing" were mainstays of the Soviet union. Some days I think GWB is a deep soviet plant.

Bush/Rumsfeld is making us all crazy.

The self-service economy - your home as a warehouse

Economist.com | The self-service economy

SO YOU want to withdraw cash from your bank account? Do it yourself. Want to install a broadband internet connection? Do it yourself. Need a boarding card issued for your flight? Do it yourself. Thanks to the proliferation of websites, kiosks and automated phone systems, you can also track packages, manage your finances, switch phone tariffs, organise your own holiday (juggling offers from different websites), and select your own theatre seats while buying tickets. These are all tasks that used to involve human interaction. But now they have been subsumed into the self-service economy...

This September 2004 article described the number of ways that service roles have become self-service. Today, as we struggled to find mittens for our kids, I realized something else had been outsourced to us -- inventory management. The modern home is a warehouse.

I see this mostly with clothing. Children's clothes are dirt cheap now, but supply is as unpredictable as quality. One day there's a deluge of small mittens. Another day it's socks. Another day hats. Then large mittens. One cannot go to the store FOR an item. One must conduct store surveillance, purchasing items of interest.

The clothing supply chain behaves as though it has no inventory.

So where's the inventory? In the home. Suburban homes of middle class Americans are pretty large, with lots of storage space. When Walmart has size M mittens, the avid shopper can buy twenty or thirty pairs. That would last us ... a week. Ok, so it's a season for most people.

It makes sense. No-one wants to hold inventory any more. It's expensive and risky. Far better to slash prices, and transfer the inventory burden to the consumer.

Global warming summary and recommendations

eBulletin - Global Warming: A Perspective from Earth History

An interesting summary. It looks like we'll see sea level rise sharply over the next 30-90 years. Maybe 10 meters higher. The solutions given current technology seem unlikely to be implemented and are not necessarily feasible.

Looks like options are:

1. Immense research into alternative energy sources. Unfortunately these don't look promising.
2. Immense investment into energy conservation -- this could decrease emissions significantly. Best funded by a serious tax on energy. Sigh.
3. Teach humans to live underwater. Hmm.

Ok, so we don't have any great options. I'd say humanity is pathetic at solving these kind of problems, but we did manage the freon transition. This is only a hundred to a thousand times harder. We must hope China will be smarter than the US.

More in the solar system than thought possible?

The New York Times > Science > Sun Might Have Exchanged Hangers-On With Rival Star

...Either encounter would also leave alien planetoids in our solar system (and some of ours in the alien system) orbiting at a steep angle to the plane in which the planets go around. And so the next step is to search for such objects.

Sedna itself has only a moderately inclined orbit, the astronomers say. A more likely candidate for an extra-solar origin is another icy wanderer, known as 2000 CR105, about half the size of Sedna, discovered out beyond Neptune in 2000. Its orbit is inclined 20 degrees to the planets.

The detection of objects with inclinations of 40 degrees or more, the authors write in Nature, 'would clinch the case for extrasolar objects in the solar system.'

Great. Planetary bodies whipping around in unexpected orbits. The article doesn't say how far out these objects are supposed to be.

Cruise ship nursing homes?

The New York Times > Health > At Sea, Care for Aged (and All You Can Eat)

For only slightly more than the average cost of a year in an assisted living residence, older people can live aboard a luxury liner with many of the same services, including meals, housekeeping and medical care at all hours - not to mention entertainment.

While it may not be a serious option for people with chronic or severe medical disorders, life at sea may have its benefits for those who can take it, according to a study in the November issue of The Journal of the American Geriatrics Society.

'A lot of people in assisted living facilities are dissatisfied with what they're paying and the services that they get,' said Dr. Lee Lindquist, an instructor of medicine at the Feinberg School of Medicine at Northwestern and the lead author of the study. 'A nice facility can be extremely expensive, and a lot of seniors have to go into their own savings because Medicare doesn't cover it. When you think about all the amenities you get, living on a cruise ship is more desirable for certain people.'

Dr. Lindquist, a geriatrician, came up with the idea for the study on a recent cruise. At dinner one night, she was chatting with some people who reminded her of her patients. Then the idea hit.

Hey! I thought of this one years ago. Except I was thinking it would make a great nursing home. Just wheel me off at one spot or another ...

On the external representation of information in string theory

The New York Times > Science > String Theory, at 20, Explains It All (or Not)

....For years physicists have looked for the origins of string theory in some sort of deep and esoteric symmetry, but string theory has turned out to be weirder than that.

Recently it has painted a picture of nature as a kind of hologram. In the holographic images often seen on bank cards, the illusion of three dimensions is created on a two-dimensional surface. Likewise string theory suggests that in nature all the information about what is happening inside some volume of space is somehow encoded on its outer boundary, according to work by several theorists, including Dr. Juan Maldacena of the Institute for Advanced Study and Dr. Raphael Bousso of the University of California, Berkeley.

Just how and why a three-dimensional reality can spring from just two dimensions, or four dimensions can unfold from three, is as baffling to people like Dr. Witten as it probably is to someone reading about it in a newspaper.

In effect, as Dr. Witten put it, an extra dimension of space can mysteriously appear out of "nothing."

Hmm. Of course if one assumes that the "universe" being described by string theory is itself a sort of simulation running on god's own computer ...

I can see why Caltech's Dabney House was so popular with physicists in the 1970s.

The NYT publishes an extensive review of string theory
