iPhone icons

Here are some lovely PSDs available for download; excellent for picking apart how to create great iPhone icons:

This will be important for iPhone apps but even more important down the road (in my opinion) for web apps that have custom icons associated with them. If you’d like to learn more about this technique, full instructions for creating a custom desktop iPhone icon for a web page or web app are right here in Jonathan Stark’s excellent go-read-this-now book on building web apps with HTML, CSS, and JavaScript:


The gist of which is essentially you are creating a 57 x 57 icon and then adding one of the two following HTML lines to identify it:

The first option inherits the glossy light effect and corner radius from the iPhone OS. The 2nd one does not, so you have to handle corner radius and any desired light effects manually. iPad icons use 72 x 72 pixel resolution. I’m not sure yet, but I’m betting the new OS will have something closer to the 72 px size. Anyone know the answer?

Should academic paper publishing embrace EPUB?

Sometime last year I was considering home improvement options to our house, I was thinking about building a large, built-in bookshelf in our upstairs study area. I always loved to see lots of books on the wall, and really enjoyed pulling down a book to have a browse on whatever subject interested me from my own personal library. But there was all this discussion regarding ebooks, and I was thinking if this ever caught on big time, then printed books would eventually go the way of the dodo – the end of their 400-year cycle of greatness was at hand, and the new way to read anything was going to be on a digital screen.

I’ve since come to my senses. I love books – the binding, the texture of fine paper, the fact that it doesn’t require a battery or power cord, and even the smell are all plusses in my book. Books have been around a long time, and they’re here to stay. Ebooks are just another channel of distribution for such content, and I believe that both have their place in the modern era.

However, for academic research papers, I think we can safely kill the paper. Particularly, I think it should all begin moving towards the EPUB format. I read a lot of academic papers in my work, and I find myself wishing that more of this stuff were published as EPUBs. In contrast to my love of books above, I think academic research would largely be much better served in a purely electronic format. It’s already going that way from the reader’s point of view, right?

Typically, when academic papers get published electronically, the format of choice is PDF. Or in earlier days, PostScript. If you’re lucky, someone had the foresight to publish their paper as HTML. The advantage of a flexible format such as HTML is that you can resize the fonts. Text can flow. It’s easier to get a clean copy of a text or data segment out of HTML than it is from PDF for quoting in one’s own paper, because copying from PDF tends to yield horrific line break issues and other artifacts on the clipboard.

PDF is, I’m sorry to say, hard to read on smaller screens. PDF expects paper, and refuses to reflow itself into smaller screen sizes such as an iPhone or Android device form factor. It barely passes on the 1024 x 768 iPad screen. Anything smaller, such as most ebook readers, is going to be unacceptable. Having to zoom in and scroll left to right to read one line of text at a time on a mobile device is not what anyone would call a user-friendly reading experience.

EPUB by contrast works great on mobile devices. Using the Stanza reader on iPhone is quite comfortable. iBooks on the iPad platform is a joy to use.

After reading this tweet by Dave Gutelius today, I was reminded of how much I hate printing out all my academic papers in preparation for travel. Flying is reading time, and printing this stuff out and stuffing it in my backpack is time consuming, a waste of paper, and added weight that I don’t want to carry.

Stuffing those papers onto my iPad and using GoodReader is a step in the right direction. But still, all too often the PDFs are formatted for paper, not for screen, and I am still cursing the format. PDF usually assumes letter-sized or A4-sized paper, and most ebook readers have physically far smaller screen sizes. Far better I think to start providing EPUB options for academic research, so that folks like me who need ginormous fonts and such can read with greater ease.

Or, should it just go to straight HTML? At that point, papers might even be able to add a little functionality to the electronic reading experience – change variables in information graphics, show rendered 3D representations of models, and so on. EPUB doesn’t support anything fun like HTML5 DOM handling or Flash, although CSS3 might work depending on the EPUB reader’s implementation. Either way, PDF ain’t fitting the bill ebook readers, and I think this sort of format will be far more important in the coming months and years as ebook-capable mobile devices become more and more commonplace.
