Apple has and always will be a consumer company. They simply struggled until there was a true consumer market. Now they find success where others have not simply because they have always had a vision of creating products for ordinary folk. Apple simply had to wait more than two decades for their true market to emerge. Now, emerge it has and its billions strong.

2-year cadence

Preparing for the iPhone Next: Rumors Analyzed | AnandTech

Trends are pretty easy to spot in the table. With the exception of the first iPhone, the industrial design appears to be on a 2-year cadence. The CPU and GPU architectures are also on the same 2-year cadence. From a silicon standpoint even the cellular architecture is trending towards the same 2-year cadence, with a few notable exceptions (e.g. GSM/CDMA iPhone 4 divide).

Based on historical trends alone it’s pretty easy to conclude that we’ll see a 4th generation chassis, a pair of ARM Cortex A9s and a PowerVR SGX 543MP2 under the hood. Add the assumption of LTE (a reasonable one to make) and you have a pretty believable story. It turns out the currently available evidence helps corroborate this, but let’s dig through what’s out there to see how this all fits.

アップルは Copland の過ちを繰り返すか

Copland 2010 revisited: Apple’s language and API future | Ars Technica
〈WWDC 2011 に対する John Siracusa の感想〉

Despite the lack of a 2010 crisis, Apple will eventually need to address this issue. The reason I was thinking about it five years ago is the same reason I’m even more concerned about it now: development platforms are hard to change. First there are the technical issues of selecting or developing a new language and creating a new API for it. Great APIs take years to develop and mature. Just look at Cocoa for a good example

The largest single collection of people who know and love Objective-C and Cocoa is at Apple, and these same people are perhaps not the most likely to aggressively push for a new language and API. Add to that Apple’s tendency—as evidenced by its App Store policies—to charge ahead with what it believes is the best course of action, despite outside opinions to the contrary, and you have some strong forces pushing Apple away from thinking seriously about this issue.

Apple can’t use another platform vendor’s API without ceding control of its destiny to an outside entity. Apple would also probably prefer not to hitch its star to a programming language predominantly driven, if not outright controlled, by a competitor. That leaves two options: either do it all in-house or find a “vendorless” solution not controlled by any single party.

The use of web technologies neatly solves many of Apple’s potential problems. Instead of having to come up with a world-beating language and API on its own, Apple’s got the entire industry working towards a solution on its behalf. The web is not controlled by any single competitor, and Apple arguably exerts as much influence on it as any other technology company.

Unfortunately, that means it’s not controlled by Apple, either. Furthermore, web technologies have a long, long way to go to catch up with the state of the art in traditional GUI application development environments. Most experienced Cocoa developers are very aware of this, and view any alternative based on web technologies with…some trepidation, let’s say.

Finally, I have to admit that I also just love a good mystery. Five years ago, I had no idea what Apple’s future language and API plans were, and today I still don’t. In a world where almost all of our longstanding fantasies have now actually come true—we’ve got our new OS, our Apple phone, our mythical tablet—the language/API successor question stubbornly remains. I’ve wisely chosen not to put a new deadline year in the title this time around, but rest assured, I’ll be watching and waiting. I just hope I’m not the only one.

福島原発1号機炉心のダメージは7割と米高官が明言

Fukushima Daiichi Plant Reactor Core Damaged | NYTimes.com
〈米政府高官が初めて明言〉

Energy Secretary Steven Chu said Friday that roughly 70 percent of the core of one reactor at the crippled Fukushima nuclear plant in Japan had suffered severe damage.

His assessment of the damage to Reactor No. 1 was the most specific yet from an American official on how close the plant came to a full meltdown after it was hit by a severe earthquake and massive tsunami on March 11.

Mr. Chu, a Nobel laureate in physics, suggested that the worst moments of the crisis appeared to be receding, saying that the best information the United States had received from the Japanese authorities indicated that water was once again covering the cores of the stricken reactors and that pools of spent fuel atop the reactor buildings were “now under control.”

In addition to the severe damage at Reactor No. 1, the Energy Department said that Reactor No. 2 had suffered a 33 percent meltdown. Mr. Chu cautioned that the figures were “more of a calculation” because radiation levels inside the plant had been too high for workers to get inside, and sensors were unreliable.

He called the nuclear crisis in Japan “a cascade of events” that led to multiple failures of backup systems. He told reporters at a breakfast that while officials were reviewing the accident to see if American nuclear plants needed significant changes, he did not want to overreact or rush into changes whose effects might not be fully understood.

“First and foremost, we are trying to make sure that fuller damage is not done,” he said.

Questioned about the long-term effects of Japan’s effort to “feed and bleed” the reactors — pouring in cooling water, then releasing it as steam into the atmosphere — he said there was an effort now under way to “minimize the release” of radioactivity into the air.

“They’re trying to reach a steady state,” he said, in which cooling could take place with minimal radioactive releases into the atmosphere.

〈海外の方が早くから危機の実態を予想していた〉

Most of these computer-based forensics systems were developed after the 1979 partial meltdown at Three Mile Island, when regulators found they were essentially blind to what was happening in the reactor. Since then, to satisfy regulators, companies that run nuclear power plants use snippets of information coming out of a plant to develop simulations of what is happening inside and to perform a variety of risk evaluations.

Indeed, the detailed assessments of the Japanese reactors that Energy Secretary Steven Chu gave on Friday — when he told reporters that about 70 percent of the core of one reactor had been damaged, and that another reactor had undergone a 33 percent meltdown — came from forensic modeling.
