Apple does things differently

I've read this before. Apple has very small, very productive, engineering teams ...
/dev/why!?!: The loss of ZFS

...I recall having a discussion with the head of a university FS team who was discussing the FS he was working on. He was pitching it to a group of Apple engineers. It was some interesting work, but there were some unsolved problems. When he was asked about them he commented that they didn't have enough people to deal with them, but he had some ideas and it shouldn't be an issue for a company with a real FS team. It turned out his research team had about the same number of people working on their FS as Apple had working on HFS, HFS+, UFS, NFS, WebDAV, FAT, and NTFS combined. I think people don't appreciate how productive Apple is on a per-engineer basis. The downside of that is that sometimes it is hard to find the resources to do something large and time consuming, particularly when it is not something that most users will notice in a direct sense...

AT&T surprise charges with added lines and phone switch

When we first switched from Sprint to AT&T I catalogued all the extra fees and surprises. Recently I switched Emily from a BlackBerry Pearl to an iPhone 3GS (very successful move) and added one child to our family plan ($10/month – in theory).

These were the surprise charges this time around:

  • $18: “one time charge for upgrade fee” for Emily’s BB to iPhone switch
  • $26: “activation fee” for my son’s added line

By AT&T standards these are minor hits. They annoy me, but I’m more annoyed that I have to pay for SMS and MMS messages I can’t block. (I’ve written my representative about those, every time I get these charges I send off another email to a federal legislator.)

We get a “national account discount” (many large companies negotiate these plans). I confirmed Emily is still receiving it after the switch, but I didn’t see it on my son’s plan. So I’ll follow-up on that with the AT&T corporate service number.

I also need to inquire if the “national account discount” should have covered the “upgrade fee” and “activation fee”.

Incidentally, when I reviewed our online account settings I discovered new options to opt out of AT&T’s despicable SMS spam.

H1N1 - things new to me

I have an average physicians knowledge of H1N1, so most of what I read is uninteresting. This MinnPost article by a local physician, however, had some real gems. Osterholm is a national expert on pandemics living in MN. His predictive record is imperfect, but he has some interesting observations (emphases mine) ...
MinnPost - Tapping Minnesota’s top H1N1 expert: Michael Osterholm

... Osterholm chairs a National Institutes of Health (NIH)-sponsored panel that tracks emerging influenza infections. This year's meeting included a group of virologists and influenza experts that Osterholm considers to be the best in the world. "And every one of them said without a question that if this H1N1 acquires a certain PB2 gene, we're in big trouble," Osterholm recalled. "Well, it did it [acquire the PB2 gene] in the Friesian islands off of the Netherlands this August, and we didn't see that. Everyone was holding their breath, but at least, so far, nothing has happened with that. And so we don't understand in many instances what components of the mutt are really critical, which ones are important and which ones don't make any difference."

... I have been concerned from the beginning about over-promising and under-delivering on this issue. Just knowing this vaccine and what it takes, when they put the 140 million-dose estimate out that would be here in mid-October, I just knew that that was going to be a great overreach....

... I find it remarkable that we have as much as we do as early as we do, given the timeline..."

Long before the arrival of the novel H1N1 virus, Osterholm and other infectious disease specialists were lamenting our country's antiquated vaccine production system, which he points out relies on 1950s technology that's slow and unreliable. And even the way in which influenza vaccines work is a little bit murky.

"On Monday, I'm giving the keynote address to the NIH vaccine research meeting," he said. "I'm actually using H1N1 to highlight the many problems we have today with the vaccine industry. It's a simple as, 'You know, we don't have a clue what protects you in a flu vaccine.' So we measure hemagglutinin [the 'H' in H1N1] using outdated measures for antigen [a molecule on the surface of a virus that our immune system uses to key in on it], but we don't really know."

"When the CDC did their sero-survey looking for hemagglutinin antibody to novel H1N1 in the elderly, they found about 30 percent of them having pretty good titers to the H1 N1 virus," Osterholm recalled. "But the bottom line is, the protection we're seeing in the 65 and older age population far exceeds 30 percent, and the point of it is that there is probably a huge part of cellular immunity that's tied to protection with the flu vaccine, and that's something we don't even understand....
... The one thing I do feel pretty good about is the safety issue. It's not because we know it from this vaccine, but from the time-tested seasonal flu vaccines we've used over the last 30 years."

So the vaccine will get here when it gets here, but do you have a sense of when the peak of infections will be?

"You know, I don't. As I said at the flu summit six weeks ago, I thought that by mid-October we'd be seeing what I call 'peak activity,' which is what we're seeing right now. That's how I thought it would build. What I don't know is how long this is going to last. Is it basically going to go into retreat for a while and then come back again in, say, December or January? We're burning through a lot of central people right now, meaning the rate of new infections is growing at such a rate that I think that we're not going to have that many [unexposed] people left in November, December or January to get a second wave...

The iMac 27: missing resolution independent OS X

Resolution independence means pixel counts wouldn't matter; very high pixel density screens needn't create itty-bitty text problems.

Once upon a time OS X 10.4 was going to have a scalable UI like this. Didn't happen. Then it was to be 10.5.

Now nobody mentions it.

On the other shore Microsoft has had some RI since Windows 95, but it's never worked quite well enough to be truly useful. Windows 7 takes RI further, but it's still not quite ready to go all the way.

It looks like the iMac 27 inch may remind aging Americans why RI is important ...
Apple iMac Review: 27 Inches and Less Chin - Apple imac 27 inch - Gizmodo

... at this pixel density, which is sharper than my notebook, it's almost too sharp, requiring me to sit closer than I would ordinarily do with a 27 inch display. I like the feeling of crispness — 16% crisper than the last generation. But my eyes feel like the pictures are being delivered by a land shark holding a laser pointer straight into my corneas, and I can feel the strain within minutes. I would have to jack up as many font sizes as possible or sit as close as I do to my MacBook to make it work for long long periods of time.
I'm as presbyopic as the next GOMER, so this matters. I'm going to have to work with this screen in the store for a while before I decide it's manageable at home. Lack of RI might save me a few hundred bucks.

The African mobile phone revolution continues

A few millennia ago I read quite a bit about "appropriate technology" applications for what was then known as "the third world" or "less developed nations".

In those days the idea was to find or invent product designs that returned value, but that weren't dependent on a lot of supporting infrastructure. Sometimes this might be a type of plow, or a type of solar oven. In the past decade or so there was a wind-up radio, More recently, there was the well intended originally MIT based OLPC laptop project

I think some of these ideas worked out, but others, like the OLPC, have been at best indirectly influential. Today's world is, despite our recent economic maelstrom, far more prosperous than the world of my childhood. These days "appropriate technology" may emerge to meet the needs of rural China or from African manufacturing, but it can also emerge in somewhat surprising ways (emphases mine) ...
Africa calling: mobile phone usage sees record rise after huge investment The Guardian

Africans are buying mobile phones at a world record rate, with take-up soaring by 550% in five years, research shows.

"The mobile phone revolution continues," says a UN report charting the phenomenon that has transformed commerce, healthcare and social lives across the planet. Mobile subscriptions in Africa rose from 54m to almost 350m between 2003 and 2008, the quickest growth in the world. The global total reached 4bn at the end of last year and, although growth was down on the previous year, it remained close to 20%.

On average there are now 60 mobile subscriptions for every 100 people in the world. In developing countries, the figure stands at 48 – more than eight times the level of penetration in 2000.

In Africa, average penetration stands at more than a third of the population, and in north Africa it is almost two-thirds. Gabon, the Seychelles and South Africa now boast almost 100% penetration...

Uganda, the first African country to have more mobiles than fixed telephones, is cited as an example of cultural and economic transformation. Penetration has risen from 0.2% in 1995 to 23% in 2008, with operators making huge investments in infrastructure, particularly in rural areas. Given their low incomes, only about a quarter of Ugandans have a mobile subscription, but street vendors offer mobile access on a per-call basis. They also invite those without access to electricity to charge their phones using car batteries.

Popular mobile services include money transfers, allowing people without bank accounts to send money by text message. Many farmers use mobiles to trade and check market prices.

... The share of the population covered by a mobile signal stood at 76% in developing countries in 2006, including 61% in rural areas. In sub-Saharan Africa, closer to half the population was covered, including 42% in rural areas...
This isn't new, the Economist and others have been covering mobile phone use in Africa for since the 1990s. It's a noteworthy and encouraging sign. It's "appropriate technology" that emerged somewhat unexpectedly, but has since received extensive support from governments and aid agencies, including Kenya's investment in new fiber optic connections.

Today these are fairly minimal phones, but Google has done some pretty ingenious things to provide voice and texting interfaces to Google services. In 3-4 years, today's simple phone users may have Android phones comparable to the iPhone of 2008.

We're gradually moving towards the Teledesic/One Laptop per Child vision, but along a less expected path.

Great news for humanity.

Use Get Satisfaction to talk to Google

Today's announcement of Google's mind reading technology (for example) tells us where the Google Reader team looks for feedback (emphases mine):
... we'd love to hear your feedback — share your thoughts on our help group, Twitter or the Reader section of Get Satisfaction, a third party support community.
Somehow I don't think my tweeting about a really obnoxious Reader bug is going to make much of an impression. On the other hand, the Get Satisfaction site is kind of neat. It's a startup that allows businesses to outsource their customer community.

It's free for customers of course, and, like all new startups, you can authenticate with Facebook, your Google ID or OpenID (without sharing your password of course).

Looks like Google is a paying customer -- they currently have 42 products on GetSatisfaction.


Google's Help Forums have always felt like a waste of time - both when they were on Google Groups and in their current incarnation. I'll give Get Satisfaction a try.

Update 10/23/09: It worked. Get Satisfaction is where Google lives now. Forget the official help forums.

Honda knows its customers

What if we paid the CEO of Honda and four of his picks $1 billion to take over GM?

Just wondering. Honda knows its customers very well ...

... The Dog Friendly components include a soft-sided cargo area kennel made from strong seat belt material netting, a cushioned pet bed in the cargo area, a 12-volt DC fan, second-row seat covers with a dog pattern, all-season rubber floor mats and a spill resistant water bowl. An extendable ramp will also store beneath the bed, so it can be accessed when the tailgate is open...
Incidentally, this post was not on my regular reading list. It was "suggested" to me by the Great God Google.

Google knows its customers even better than Honda.

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

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.
