Two quick links on Cognitive Load Theory I've been fielding lots of questions lately about Cognitive Load Theory. Here are two quick links that may be useful. First is an article talking about the practical implications of CLT on the design of learning. The second are some "recent" (as of 2003) developments regarding CLT. Happy reading! Update: I clarified the second...

Practical advice on kids and Android app development After hearing about my students' success developing an Android app, I've gotten several emails asking for more details as to how I practically worked with my kids. Here are some pointers that I offered to the first person that emailed me, perhaps they are of some use to you. Please note that your mileage may vary. It's ok to not be...

Publishing an App Inventor app to the Android Market As I mentioned earlier, my students and I published an Android app to the Android Market. See those links for more information on the background. This post is decidedly technical. First, once we finished the coding process, we packaged the app for to download to the computer. This is an option in App Inventor. This downloaded an .apk file....

Designing and publishing an Android app with kids This post is designed to provide some context around how/why we decided to build this app. The more technical details of the code and how we published it will come in a future post. My students and I recently completed and published an Android app, and here's how we did it. First, the genesis for this goes back to a question I asked...

Create password-protected pdf files on your mac

Category : Software

So I saw this post by lifehacker some time ago and as is my habit, I marked it to view later and decided to check into it when I had some time.

Today, I had a little time.

I have figured out (after reading page 2 of this article) how to create password-protected pdf files using a free script and Automator. Here is how I did it…

NB: I am not a command-line junkie, so I went with the automator scripting style, if you love the command control, read here for how to work that out.

Start by downloading this script.

Then just double click to extract the installation package and double click that to install the package itself.

Easy, right?

Next you need to hit up Automator to set up the workflow. Check out this giant skitch’ed screenshot of how to set it up. It should be fairly straightforward, but let me know if it’s confusing. (click pic for full size)

So try it out once you’ve got it set up! It worked great for me once I tweaked it like you see it.

I also have the workflow here for you to download, set up just like I have it, if you’d like.

add_password_to_pdf.zip

So the simple, easy set up works like this…

1. Download pdfauxinfo. Install same.

2. Download my Automator workflow.

3. Run the workflow, select the file, and click run. Done.

On a side note, I did try this on both my mac and my pc, and both platforms ask for a password before opening and limit access, depending on how you configure it.

I am not calling this method foolproof and I am sure it is easily hacked. Truth is I am happy to have learned more about Automator. Have fun!

All screenshots are done using Skitch.

Chris, couldn’t you just use the native Mac app, PDFLabs to accomplish encrypted files?

I suppose I could have, thanks for the link to a nice piece of software, downloaded and installed already!
