Page Turned on the eBook?

Thursday, March 12th, 2009

It has been an exciting couple of weeks for eBooks!

O’Reilly Adopts Bookworm

O’Reilly Publishing has adopted Bookworm, a web site for online eBook reading and storage. Bookworm is built on open software and the open epub standard. Bookworm looks pretty slick!

Once you upload your ebooks, you can transfer them from Bookworm to the Stanza app on your iPhone. Unfortunately, Stanza is still kind of rough around the edges. Paging is little different from Palm-era ebook readers, and pre-formatted text often gets cut off at less than its full width.

Still, my enthusiasm for the epub standard makes me think Bookworm itself has a good chance to succeed, at least to some extent. epub piggybacks on HTML, and consequently has good support for things like tables. There is also support for generating epub content from books expressed in another attractive format, DocBook XSL.

Kindle for iPhone

Then, Amazon released a Kindle App for the iPhone.

Kindle for iPhone seamlessly downloads all your purchased Kindle content and can sync your current page across iPhone and Kindle Wireless Reading Device (”Kindle”).

The App is pretty well done. Paging is accomplished using the cool finger-flit motion familiar from other iPhone apps.

However, unlike Stanza and the Kindle Wireless Reading Device, there’s no integrated search. And the Mobi format underlying Kindle content still lacks support for real tables.

Perhaps most disappointingly, there appears to be no way to load content that was not purchased through Amazon into Kindle for iPhone. Hopefully, this facility will come soon, along with some way to read Kindle content on a Desktop.

Nevertheless, having all my Kindle content available to my iPhone has proven to be convenient. It’s especially useful for reading when your range of motion is limited, like on a crowded train. The iPhone also makes it possible to read in the dark or in extreme cold. The e-ink technology that underlies the Kindle Wireless Reading Device looks great, but it isn’t backlit and the tiny little colored spheres that underly it won’t spin properly at low temperatures.

Effectiveness and Efficiency

Saturday, January 17th, 2009

This holiday season, I received two books describing how we can help the environment.

The first one, the New York Times’ green book, was a disappointment. The celebrity vignettes were well-intentioned, if at times bizarre (William McDonough and Cameron Diaz?)

Some of the advice in this book isn’t very good. Take the following travel tip:

Seek out locations that aren’t overexposed, overcrowded, or in environmenmentally sensitive areas. Overcrowding in already densely populated areas can lead to increased pollution by wastewater, garbage, heating, noise, and traffic emissions.

Unfortunately, the impact of tourism on the environment is more complicated.

As any trail designer will tell you, concentrating visitors in certain areas can actually be good for the environment, because it limits overall damage. Similarly, it hurts the environment less to ride the teacups at “overexposed, overcrowded” Disney World than it does to ride an airboat through the environmentally sensitive Everglades.

But you can also visit the Everglades without particularly hurting the environment, provided you stay on the boardwalks and paved paths. In fact, you might become so enchanted with the amazing bird, alligator, and otter populations that you are moved to reduce your environmental impact upon returning home.

What’s more, income from legitimate eco-tourism empowers some communities to avoid unsustainably harvesting their natural resources!

We generate pollution everywhere. In a densely-populated city, the larger shared buildings waste less heat. Destinations are closer together, so we don’t have to drive as far. That means less pollution, not more.

The chapter on school advises:

Try using a digital library or the World Wide Web instead of traveling to your local branch to do research. You’ll save time and money. The circulation of books from public libraries is 1.9 billion a year, or about 7 items checked out per person. If every American checked out and researched online a single book a year, we would save three hundred million trips to the bookshelves.

These numbers sound fishy to me, but let’s assume they’re right. Let’s further assume that no one ever walks or bikes to the library, which has minimal environmental impact.

I’m all for the Internet, but do we really want to discourage kids from using the library? The Internet is a gigantic but profoundly non-authoritative source of information. Information published in books has to pass a higher threshhold of quality and suitability.

Electronic books are great, but the availability of titles remains limited. And e-book delivery platforms are still pretty expensive.

In order to function as citizens of a participatory democracy, it is imperative that we remain well-informed. Without resources like libraries we wouldn’t be able to cope effectively with the challenges that affect our environment.

Then the chapter on work goes on to give this contradictory advice:

More than two hours of the average office worker’s time is used per day sending e-mails and surfing the Internet. Internet data servers use as much energy in the United States as is used by all U.S. TVs combined.

And the final fifty-one pages of the book are, you guessed it, references to Internet data servers! Why pulp trees to print web addresses that will already be out of date when the book is published? Why not set up a single web site, include the URL at the end of the book, and maintain links to everything from there?

Clearly, there is work to be done improving the energy efficiency of Internet server farms. Instead, the authors of the green book would have us to communicate and read less! Unless we’re using the Internet to avoid a trip to the library.

It is unreasonable to expect that we should stop living our lives to help the environment. Ultimately, the whole point of environmentalism is to enrich our lives by securing the wonder of nature for ourselves and our descendants.

The book’s saving grace is a page on which Will Ferrell recounts the “limitless joy” that driving his electric car to the hazardous waste facility affords him. For my money, they should have let Ferrell write the whole book.


I’m glad to say that I really did enjoy Living Like Ed, A Guide to the Eco-Friendly Life, by Ed Begley Jr. Ed is the real deal. His book is full of great information, much of which I had never read anywhere else.

Look to Windward

Sunday, October 14th, 2007

Josh has a new article up about “spacediving”. The enormous speeds we ordinarily associate with atmospheric re-entry result from de-orbiting. If you just go straight up and straight down, re-entry speeds are reduced to the point where spacediving ceases to be impossible and becomes merely gonzo-stupid.

Proceeding from this premise, the beryllium heat shield on Alan Shepherd’s Freedom 7 Mercury Spaceship must have been fairly over-designed. Freedom 7’s non-orbital, ballistic trajectory reached a top altitude of 187 kilometers (116.5 miles). If you dropped an anvil from this height through a vacuum, it would hit the ground at about 1,755 meters per second (5,758 feet per second.) Of course, in Earth’s atmosphere the anvil would reach terminal velocity before achieving this speed.

15 minutes and 22 seconds after blast-off, Freedom 7 splashed down 486 kilometers (302 miles) from its launch pad. That corresponds to an average Eastward velocity in the same ballpack as our idealized anvil — about 527 meters per second (1,730 miles per second.)


Cringely has a surprising article this week about the use of giant kites to harvest electricity from the wind. The hardest part of flying a kite is launching it, and I’m a little hazy on how they plan to get these monsters off the ground, where the windspeed is modest. But the proponents think they can generate electricity for the game-changing price of 0.5 cents a kilowatt hour. Forget windmills, this price beats coal. Reportedly, the Google People are involved, which suggests this is science fiction rather than fantasy.

It’s gratifying to see somebody draft aerospace engineering to fight global warming. I’m reading an interesting book, Break Through: From the Death of Environmentalism to the Politics of Possibility, which suggests that efforts to reduce global poverty can also help combat global warming. The conventional wisdom says that economic progress will result in more industry and therefore more pollution. The authors of Break Through argue convincingly that nations must escape poverty before they feel secure enough to focus on environmental issues and expend the kind of resources necessary to really secure rain forests and reduce greenhouse gas emissions. The authors advocate a new Apollo project (again with the aerospace engineering!) to jumpstart large-scale clean technologies that we can share with them and, of course, use ourselves.

I’ll keep riding my bike to work, but this is good stuff.

Text Patterns

Sunday, March 12th, 2006

I wrote a short computer program to generate a tiny snapshot of the structure of a text document, and used it to make a quiz.
