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...

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....

How to install SMART Notebook software on a 64 bit Ubuntu machine

Category : General

I have been struggling for the last 2 hours to install SMART Notebook for Linux.

They place their software for download packaged with autopackage. This is designed to make the installation easy, but it has been anything but.

You see, I am running a 64 bit version of Ubuntu 9.04 server, and autopackage is designed for 32 bit machines.

So, when I initially clicked the autopackage, it gave me an error indicating that I needed to install compatibility libraries, but never listed which ones.

Here is the ultimate solution, you have to trick the autopackage into thinking it is on a 32 bit machine.

When I first ran the installer in 32 bit mode (after typing linux32 at the command prompt) the system looked for certain dependencies (i.e. glib utility library) which it claimed were not installed. It was partially right, in that more specifically the 32 bit libraries were not installed.

So I had a thought, and this series of commands worked (thanks to this random forum post for the inspiration). I am watching the software install right now!

Before you do anything, I suggest you download and untar the Linux tarball. Then rename the directory and the .package file. I renamed them both smart and smart.package respectively otherwise it is really difficult to work with since they are such long file names with spaces. Ordinarily that’s no problem since you can use the graphical interface to install it, but not in this case. Then follow the series of steps below.

1. First, type this in the command line “sudo apt-get install ia32-libs” (with no quotes)

2. Then type “linux32” (with no quotes)

3. Then type “sudo package install smartfilename.package” (no quotes, and substituting in the file name of the downloaded .package file).

4. Watch it install.

It is installing the large gallery files now, we’ll see how it works.
