Complimentary Copies

cp@charlespetzold.com — Thu, 02 Feb 2012 17:00:00 GMT

When an author gets a book published, the publisher generally gives the author 10 complimentary copies of the book. Usually the author signs these books and gives them to all his friends, but then he has 7 or 8 copies still left over, and these tend to gather dust on the bookshelves of the author's home.

Windows 8 Touch Events Interactions

cp@charlespetzold.com — Wed, 01 Feb 2012 12:00:00 GMT

During the week in September that I was attending the Microsoft Build conference and learning all about Windows 8, only one topic made me gloomy: This was the Windows 8 implemention of the Manipulation events. These events provide a high-level application programming interface to touch input, so obviously they are very important.

Happy 75th Birthday, Philip Glass!

cp@charlespetzold.com — Tue, 31 Jan 2012 10:00:00 GMT

About 14 months ago I saw the New York premiere of Philip Glass's Concerto for Violin and Orchestra No.2 at Carnegie Hall performed by violinist Robert McDuffie and the Venice Baroque Orchestra. McDuffie had commissioned the Glass work (subtitled "The American Four Seasons") for a program that also included the four violin concertos collected by Antonio Vivaldi as The Four Seasons almost three centuries earlier, and McDuffie took the program on a tour of 30 American cities.

The Last Catfish in the East Village?

cp@charlespetzold.com — Mon, 30 Jan 2012 18:40:41 GMT

People who live in New York City often inhabit tiny apartments, and the only reason we tolerate them is that we've exchanged private spaces for public spaces. We can frequently be found not in our apartments but walking around outside, or in a store, or a theater, or a concert hall, or a museum.

Rick Santorum and Group Marriage

cp@charlespetzold.com — Sat, 07 Jan 2012 15:31:20 GMT

One of the most common arguments against same-sex marriage is that it would open the floodgates to all sorts of other types of marriage. For example, James Dobson in his book Gay Marriage: Why We Must Win This Battle (Multnomah, 2004) writes:

Parsing CSS for EPUB

cp@charlespetzold.com — Mon, 26 Dec 2011 18:33:30 GMT

I've been trying to build an EPUB viewer for Windows 8, mostly because I want to read books on the Windows 8 tablet I got at the Build conference, and it's more fun writing one's own application rather than using someone else's. This will obviously not be a commercial product or I would have thought of a snappier and less wonky name for the program than The New Epublic! [I've decided I don't want to distribute the code at this time. — Jan. 5, 2012]

Windows 8 Dependency Property Strangeness

cp@charlespetzold.com — Mon, 05 Dec 2011 12:00:00 GMT

If this blog entry popped up in a search engine because you're having problems with defining and/or animating dependency properties in the Windows 8 developer's pre-release, you might want to jump towards the end. The early paragraphs merely discuss some deadly boring Windows 8 program I've been developing.

Very Bad Writing

cp@charlespetzold.com — Fri, 25 Nov 2011 12:00:00 GMT

About 35 years ago I picked up a novel from the coffee table in my mother's house and started reading. This particular novel was a big bestseller at the time and I was curious what made it so popular. Sure enough, I discovered a story with the annoying addictiveness of potato chips, and I suspect I finished the whole puffy bag in one sitting.

Hilary Hahn and the Ives Violin Sonatas

cp@charlespetzold.com — Mon, 21 Nov 2011 12:00:00 GMT

Three years ago I read that Hilary Hahn had recorded the Schoenberg Violin Concerto, and I was certain that must be a mistake. Surely the reference was to the violin concerto by Arnold Schoenberg's student Alban Berg. I wasn't even sure that Schoenberg had composed a violin concerto!

.NET Streams and Windows 8 IStreams

cp@charlespetzold.com — Tue, 08 Nov 2011 14:03:46 GMT

I am currently engaged in writing an EPUB viewer for Windows 8. EPUB is a popular format for electronic books. The standard is maintained by the International Digital Publishing Forum (IDPF), and that's where you can find the documents that make up the EPUB specification. (I am basing my work on version 2.)

Asynchronous Processing in Windows 8

cp@charlespetzold.com — Mon, 07 Nov 2011 12:00:00 GMT

A typical book about Windows 8 programming is likely to be rather oddly structured: It may start out like conventional programming tutorials with "hello world" but very early on the book will likely devote a chapter to a topic commonly relegated to the advanced techniques section: "Asynchronous Processing".

TODO: An EPUB Viewer for Windows 8

cp@charlespetzold.com — Tue, 01 Nov 2011 12:00:00 GMT

For a couple years now I've seriously considered participating in National Novel Writing Month by joining hundreds of thousands of other crazy writers who spend the month of November writing a novel in 30 days. But not this year. This year I want to spend November in the somewhat related activity of coding an e-book reader for Windows 8.

Phree Book Reader Now Available

cp@charlespetzold.com — Mon, 31 Oct 2011 11:41:44 GMT

I don't know how many people still read MSDN Magazine, but over the past several months I've used my monthly column (called "UI Frontiers") to put together a rather substantial Windows Phone program that lets you search, download, and read free plain-text e-books from Project Gutenberg, the repository of over 30,000 public-domain books.

Happy 80th Birthday, Sofia Gubaidulina!

cp@charlespetzold.com — Mon, 24 Oct 2011 12:00:00 GMT

During much of his lifetime Dmitri Shostakovich (1906 – 1975) was the dominant figure in music in the Soviet Union, yet he failed to provide a model that could be emulated by younger composers. Particularly during the Stalin years, his music would often incur the suspicion of the government; yet outside the Soviet Union, this same music was considered hopelessly reactionary. (Pierre Boulez called him "the second, or even third pressing of Mahler.") To Soviet authorities, Shostakovich's politics were often suspect, yet in the rest of the world he was widely perceived as a government lackey.

Car Wellness

cp@charlespetzold.com — Thu, 20 Oct 2011 12:00:00 GMT

Soon after I started reading books on my own, I tried reading books in the car, and very quickly discovered this wasn't such a great idea. After a couple incidences of "Mom, I'm going to be sick right away," my mother banned me from reading in the car. Now when I think back about the long car trips we took when I was a kid, I can only picture myself staring out the passenger-side window, my chin on my hand, bored out of my mind and wishing I were reading a book.

SpinPaint for Windows 8

cp@charlespetzold.com — Sat, 01 Oct 2011 13:20:05 GMT

Recently I've been trying to remember the last time I wrote a program that targetted the native Windows API. I think it was 2002, when I used C and the Win32 API to write the last of a series of programs for the PC Magazine Utilities column. But even at that time, I had already moved on. In the summer of 2000 I was introduced to the .NET Framework and the marvelous language C#. I became a strong advocate of managed code, and I really haven't had any reason to return to the world of message loops and wayward memory pointers. I already paid my Windows API dues, and plenty of them.

Adventures in Electronic Music

cp@charlespetzold.com — Thu, 29 Sep 2011 22:27:58 GMT

In the late 1970s and early 1980s, I designed and built several electronic music instruments, including a computer-controlled digital synthesizer capable of generating 80 simultaneous sine curves combined into 40 simple-FM voices.

Reading “The Fatal Gift of Beauty”

cp@charlespetzold.com — Sat, 03 Sep 2011 02:30:41 GMT

Sometimes it seems a miracle that people can communicate at all. Our face-to-face conversations comprise a medley of phrases, half-words, grunts, hums, hesitations, grimaces, and gestures. Only slivers of visual imagery and sound are perceived by the senses, and the brain strives in fill in the blanks. Everything is then interpreted in accordance with — and building upon — our unique inner lives. How easy it is to mishear a word, misread a smile or wink, and completely invalidate what we thought we heard or saw. It's a wonder that we don't daily collapse in complete surrender to confusion and embarrassment.

“The Trojan Women” at Franklin Stage

cp@charlespetzold.com — Thu, 25 Aug 2011 14:54:37 GMT

Even before the play begins, sentries in camouflage fatigues guard the refugee camp. Fenced off with wire, the area is littered with the detritus of a defeated nation after a devastating 10-year battle. What were once residences and industry are now piles of cinder blocks, plumbling, and unrecognizable machine parts. Two television sets have mysteriously survived this destruction only to play nothing but endless cycles of images of war.

Rick Santorum Wants Into Your Bedroom

cp@charlespetzold.com — Mon, 01 Aug 2011 12:00:00 GMT

Just fifty years ago, birth control was illegal in the state of Connecticut. The law specifically prohibited "any drug, medicinal article, or instrument for the purpose of preventing conception," and also applied to someone who "assists, abets, counsels, causes, hires or commands anyone" to use these means of birth control. The punishment was a fine of at least $50, and a jail sentence of between 60 days and one year.

Freedom and Population

cp@charlespetzold.com — Wed, 20 Jul 2011 16:11:34 GMT

"Hell is other people" says a character in Jean-Paul Sartre's play No Exit. Well, maybe sometimes. But most of the time our lives are enriched by other people, whether it be in a friendship, or a romance, or a family, or a classroom, or a party. Our lives are also enriched by people who we know only through the novels they've written, or the music they've composed, or the art they've created. In a very real sense, life is other people, and our relationship with them.

Reading “The Better Angel: Walt Whitman in the Civil War”

cp@charlespetzold.com — Mon, 30 May 2011 11:38:10 GMT

The sesquicentennial anniversary of the American Civil War has certainly increased the number of books coming out on the subject, but this has always been a healthy area of book publishing. Perhaps the big difference now is that people seem to be reading more of them. Of the several books I used in researching my blog entry on John Brown's raid on Harpers Ferry, perhaps the one most fascinating to me was Elizabeth R. Varon's Disunion! The Coming of the American Civil War, 1789-1859 (University of North Carolina Press, 2008) because it focused on the concept of the Union, which was originally somewhat amorphous until it became threatened by the conflict over slavery.

The Lost Opportunity of the "Atlas Shrugged" Movie

cp@charlespetzold.com — Fri, 27 May 2011 20:13:33 GMT

I still have the $1.75 Signet paperback of Atlas Shrugged that I read sometime in the mid-1970s. Fortunately I was old enough to emerge from the experience without permanent scarring. By that time in my life I head read enough real literature to recognize the inferiority of Ayn Rand's cardboard characters and leaden prose. Regardless, there was no denying that in Atlas Shrugged she achieved a marvelous narrative drive with a skillful arrangement of toy soldiers in an epic battle between collectivist cretins and industrialist gods.

Windows Phone Screen Shots

When I was at Tech Ed in Atlanta recently, someone asked me how to do screen shots of Windows Phone programs. You might need screen shots if you're writing a book, article, or blog entry about Windows Phone programming. Screen shots are also required when you submit a program to the Windows Phone Marketplace.

We Got Mangos And Bananas You Can Pick Right Off The Tree

cp@charlespetzold.com — Fri, 20 May 2011 03:26:07 GMT

I suffer from an affliction where certain words trigger songs to start playing in my head. The word "summertime," for example, triggers the George Gershwin song from Porgy and Bess. (I once told my mother than "Summertime" was my favorite song, and she said "That's funny. I used to sing that song to you when you were an infant and I was carrying you around the apartment.")

Coding for Multi-Touch for Silverlight 3

Two weeks ago, at the second-day keynote at the Microsoft Professional Developers Conference (PDC), Windows and Windows Live Division President Steven Sinofsky told us that Microsoft would be giving everyone there a new Acer notebook computer. He got a big round of applause. Nothing quite excites a roomful of programmers more than free hardware.
