ePubs and the Future

I have been working on various ebook projects and am frustrated by the amount of "hand coding" required to make an ePub book work well with several reader applications. When a book looks just right on one reader, it looks odd on another. Yet, we know the future is digital.

Most computer users are familiar with Adobe's ubiquitous Portable Document Format (PDF). The benefit of using PDF files is that a file includes all graphics, fonts, and layout information. A file appears nearly identical on every computer, tablet, handheld device, et cetera. A magazine in PDF looks like the designer intended — and design is the emphasis of the entire Adobe product line. Adobe's Creative Suite applications are for designers, not writers.

ePubs take a different approach, closer to the original intentions of HTML and similar document "markup" formats. Yes, you can put words in bold or change a few colors, but the intent of ePub is to allow the reader, the computer user, the ability to control specific font choices and even some layout choices. Content, not visuals, are the focus of ePub files, which are coded in a mix of HTML, CSS, XML, and plain text.

Both ePub and PDF have their roles in the digital age. ePubs let a reader easily change the appearance of a text to improve readability (the speed at which text is decoded), while PDF maintains original artistic intent. For example, most magazines are visual publications and the text is somewhat subordinate to visuals. A classic novel? The words matter. One way I consider which is the better format is by asking myself if a text would be appropriate in audio format. Audiobooks definitely don't emphasize visual design.

While I can create "perfect" PDF publications using almost any application on my computer, I can't seem to create an ePub that doesn't need some tuning. It is annoying and even absurd that software companies cannot accurately and completely generate a basic document format. Come on, software developers, HTML has existed since 1992 and SGML traces its history back to GML of the 1960s. You cannot create a good ePub editor based on more than 40 years of markup history?

There is no excuse for ePub generation to be so sloppy from most word processors, layout software, and XML editors. When a program gets the actual pages right, it doesn't include proper metadata. When the metadata are correct, the order of book elements is either incorrect or poorly maintained. I've tried InDesign, Pages, eCub, Sigil, and Oxygen. Each one is almost, but not quite, standards compliant.

We know that the ePub format, along with the .Mobi/PRC (Kindle) format, is where publishing is headed. Right now, ePubs are still in the early days, similar to the first years of HTML editors. That's a shame.

Slowly Rebooting in 286 Mode

The lumbar radiculopathy, which sounds too much like "ridiculously" for me, hasn't faded completely. My left leg still cramps, tingles, and hurts with sharp pains. My mind remains cloudy, too, even as I stop taking painkillers for the back pain and a recent surgery.

Efforts to reboot and get back on track intellectually, physically, and emotionally are off to a slow, grinding start. It reminds me of an old 80286 PC, the infamously confused Intel CPU that wasn't sure what it was meant to be. And this was before the "SX" fiascos, which wedded 32-bit CPU cores with 16-bit connections. The 80286 was supposed to be able to multitask, but design flaws resulted in a first-generation that was useless to operating system vendors.

My back, my knees, my ankles are each making noises like those old computers.

If I haven't already lost you as a reader, the basic problem is that my mind cannot focus on one task for long without exhaustion and multitasking seems…

MarsEdit and Blogging

MarsEdit (Photo credit: Wikipedia) Mailing posts to blogs, a practice I adopted in 2005, allows a blogger like me to store copies of draft posts within email. If Blogger, WordPress, or the blogging platform of the moment crashes or for some other reason eats my posts, at least I have the original drafts of most entries. I find having such a nicely organized archive convenient — much easier than remembering to archive posts from Blogger or WordPress to my computer.

With this post, I am testing MarsEdit from Red Sweater Software based on recent reviews, including an overview on 9to5Mac.

Composing posts an email offers a fast way to prepare draft blogs, but the email does not always work well if you want to include basic formatting, images, and links to online resources. Submitting to Blogger via Apple Mail often produced complex HTML with unnecessary font and paragraph formatting styles. Problems with rich text led me to convert blog entries to plaintext in Apple Mail and then format th…

Let’s Make a Movie: Digital Filmmaking on a Budget

Every weekend a small group of filmmakers I know make at least one three-minute movie and share the short film on their YouTube channel, 3X7 Films.

Inspired by the 48-Hour Film Project (, my colleagues started to joke about entering a 48-hour contest each month. Someone suggested that it might be possible to make a three-minute movie every week. Soon, 3X7 Films was launched as a Facebook group and members started to assemble teams to make movies.

The 48-Hour Film Project, also known as 48HFP, launched in 2001 by Mark Ruppert. He convinced some colleagues in Washington, D.C., that they could make a movie in 48 hours. The idea became a friendly competition. Fifteen years later, 48HFP is an international phenomenon, with competitions in cities around the world. Regional winners compete in national and international festivals.

On a Friday night, teams gathe…
