Watch your eyes...it's the sandbox

Playing in the remote "sandbox" to learn about Linux and the command line interface, I guess I'm having the urge to test the boundaries.

I decided to use less to view About_these_files.odt , but was warned it may be a binary file and asked if I wanted to see it anyway. I typed y. I wanted see if it was the way to say yes, and I figured that whatever it showed me would be a lesson, for there are no secrets in Linux. When I pressed enter a process was initiated that led to a huge spread of highlighted characters:

I had to open a second terminal window to continue entering commands. I was able to close the initial terminal window, but had to interrupt whatever process was happening to do so.

So that's a boundary...or is it?

I then discovered through the file program that About_these_files.odt is an OpenDocument Text file, which is an XML-based file format, and though this was not human-readable, the XML structure of the characters was a little bit familiar.

I guess I started playing around because the tutorials on entering commands frustrated me a little. One was a narrated screencast, the other is a very wordy description of what commands mean; both required a lot of referring from the notes to the source to the terminal, etc. It was a relief to get to the third tutorial, essentially a list of commands.

In a way I wish I were playing with my own files, which I am constantly shuffling around in Windows Explorer, to really experience the effects of the commands I am making. I care a lot more about where the dianes_private_pics directory goes than where the /usr/share/xrdp directory goes. But at least it's hard to do damage in the sandbox, right?

Ubuntu bug fixes

Just registered for the forum at http://ubuntuforums.org and started reading up on using the forum and reporting bugs (http://ubuntuforums.org/showthread.php?t=1011078). I feel like an unpaid intern/deckscrubber traveling with a boatful of biologists. I'm learning how to track down bugs in new lands, identifying them, knowing I'll be rubbing at my own painful bites while I try to describe the bug to keep others from being bitten.

What I'll be looking for in the next weeks running a Linux OS on a virtual machine is whether I'll learn it enough that I can one day throw out Windows altogether. The trick is that my family all works on one machine, and my husband needs an operating system that lets him use Microsoft Word and other office programs, as well as the internet, as effortlessly as possible. He doesn't care about open-source vs. proprietary because he is up to his ears in lesson plans. (My son, on the other hand, is 7 turning 8, and is eager to tinker around. Maybe too eager.)

We shall see whether the class that's guiding me through all of this will move me from novice to personal tech support, Ubuntu division.

The right tool for the job

I experienced some frustration last semester due to an assignment that used the wrong tool for the job. The assignment was a 15-minute narrated Powerpoint presentation each student was expected to record for the class. The tool was...dum da dum dum DUM: Elluminate Live.

See that word? Live?

Elluminate Live is not great software in my experience, but I'm willing to attribute some of the queasiness I have felt while using it to the fact that my professor, my classmates, and I were trying to have live interaction, despite the fact that one was in Arizona, another in New Jersey, another in Vancouver, and so on. It's the "Live"-ness that's challenging.

Meanwhile, recording a narrated powerpoint has nothing to do with "Live"-ness. Screencasts are one way to do it, with Jing available for free for casts under 5 minutes. Camtasia is designed in part for recorded powerpoint presentations. It's free for a 30-day trial, plenty of time for a class to use it for a project.

Instructors who use site-licensed software should be advised that just because they can, doesn't mean they should. And today's students are often the best resources for which software is the best tool for the job.
