Go Back and Forth Fast in Preview

If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.

The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).

 
 

Calepin Redux: Minimalist Blogging Platform Goes Open Source

Send Article to a Friend

Back in January, I wrote about the Dropbox-based blogging service Calepin (see “Calepin: Simple, Minimalist Blogging with a Twist,” 5 January 2012). Since then, I have used the Calepin platform to publish various short essays and to share fragments of family trees with members of my extended family.

However, Jökull Sólberg Auðunsson, the man behind Calepin, has been unable to keep up with the demands of running the service. In a recent letter to subscribers, he wrote: “I work full time as an interactive director at an advertising agency, so it is hard for me to develop Calepin into a business.”

In response to his lack of time, Jökull has decided to release Calepin as open source, hosted on github. This means that anyone who wishes can run a Calepin server, assuming sufficient technical skills and an available server.

Jökull will continue to support those people who wish to run their own servers, but the future of the original Calepin server is unclear. 60 days ago, he tweeted that the service would be shutting down in 90 days.

While I am saddened to see the Calepin service go away, its forthcoming demise drives home one of the points I made in my original article: If the service disappears, for whatever reason, I will have lost only the public face of my blog, not the actual data that I posted there. All of my articles live on my laptop, in my Dropbox folder. I don’t have to worry about “getting my data out” of Calepin, because Calepin was hosting only a copy of my original data. Compare that, if you will, to people who scrambled to get their data off of MobileMe before the 30 June 2012 cutoff date.

For those who are looking for a Calepin replacement, check out Scriptogr.am, which looks and works much like Calepin and which can probably take over for Calepin in a matter of minutes. For those who want to host their own Dropbox-driven blogging service but can’t figure out how install Calepin, there’s also Ian Landsman’s Kudos, which may be easier to install and maintain.
