Creating Videos for Assignments

In several of my classes, students are required to create video screen captures to turn in as assignments. Here are a few things to note about those video captures:

1. Captures may be done on any platform as long as the instructor can watch the video using youtube (e.g. you uploaded it and gave me the link) or a format that VLC recognizes.

2. Video file size does not exceed eclass size limits (currently 50 mb) or you will need to put it on youtube.
3. Video dimensions do not exceeed 1080P - 720P is preferable. 4x3 size is ok too. 1024x768 is great, and you can make them whatever works best for you!
4. You may use any capture software you want. The following are ones known to work as of this writing:

   1. QuickTime (Apple)

   2. Open Broadcaster Studio (Apple, Linux, or Windows) This one is installed in the lab as of 2017. If you wish to talk, make sure to bring a microphone. I believe the headset for your phone will work with the computers in the General Lab too.

Approaches to solving Computer Problems

There are really two types of problems in Computer science. First, there is the kind you program a solution to. It has complexity that must be dealt with or you will soon pull your hear out trying to figure out what it is you did or are doing or yet need to do. The second kind of problem is one you are trying to find the cause of, and then find a solution to. These are usually found in systems and relate to configurations or hardware problems.

Dealing with complexity when developing Solutions

To deal with complexity you will often employ one or more of the following concepts:

Approaches to Finding and Fixing Configuration and hardware issues

To find the cause and fix configuration and hardware problems, you can approach the problem using these three techniques:

1. Use a Knowledge Base - It could be Google, but it may be your own companies wiki or some other documentation source. Find it in the knowledge base and following the instructions to fix it. This is the easiest, fastest and will solve most of your problems.
2. Follow the path - This is a bit harder because you may not know the path. I frequently find myself following the path of some errant connection in the data center. Sometimes its just a bad wire, sometimes a student has moved a wire without telling me. For network issues a loop-back test may be in order (e.g. in the simplest case ping), in other cabling situations, you could try Frogging. This method works well for systems that must communication, and where communication is breaking down. It also works well in processes that require sequential actions. It requires more work and it is a bit better in its success rate too.
3. Hypothesis testing - Now we are talking hard work. This is science at its core: you hypothesize a cause and develop a way to test your hypothesis. You might be right in your hypothesis, but it may not be complete. Think of problems that manifest themselves from multiple causes. Although its the hardest, it is also the most successful method. It also takes the longest. So start at the top and work your way down to here as a last resort.
