Preview 7 vs Preview 8

Preview Icons

What happened to the that little boy on the Preview Icon?

Preview plays a big part of my workflow for reading and annotating PDF’s stored in Papers 3. I highlight, circle things, and add a lot of text, then all annotations are saved automatically back into the Papers library. Preview and Papers work together more smoothly than PDF Expert and Papers for the iPad. On the iPad, I use PDF Expert to do the same and Preview 7 and PDF Expert worked beautifully together.

March 14th, or π-day, this year takes on additional numerical significance. Only once in a hundred years we are able to celebrate π to its billionth decimal place.

I wonder if Galileo Galilei geeked out on 3/14/1592 6:53:59.

In other mathematically geeky news, while doing several calculations on my Mac I was longing for my old HP scientific calculator with reverse polish notation. Looking through the Mac app store at all the emulators, I decided to see if the built-in calculator app had this feature. And guess what it does.


In the View menu, you can select “RPN mode” and now you get a calculator with a stack visible 2 deep. I don’t know if this was possible in previous versions of OS X, but I love the geeks at Apple that made this happen.

Happy π-day. Now we wait for May the Fourth.

CORD 2014 – There’s an App For That (Paperless Edition)

CORD-Anniv-FinalLogoHello CDEM and CORD attendees. Each year for the past few years, a colleague and I have presented some of the most useful apps of the past year. This year, Jason Wagner (@TheTechDoc) and I have been asked to do the same.

Feedback from those previous sessions really focused around providing demonstrations rather than just a list and description of what applications we found useful. Respecting our time constraints, I’ve put some quick demonstrations of useful software below. I will be spending most of my time talking about screencasting software and principles, but I’m happy to discuss any thing (here or at the conference).

1password demo

Part of the “There’s an App For That” talk Rakesh and I have given at CORD has included software recommendations. People requested demonstrations of how to use the software. So here’s the first one, 1password for iPhone (also available for iPad, Mac, PC and Android).
