URIx-Util [Update 2]

I now have the library working on the Raspberry Pi! A new GitHub repository, called Radio-SIP, has spun up with an implementation of the library [link]. (All of the development has been happening on a different branch. I'll move things to master once the gem for URIx-Util goes live.)

When it is all set up, the topology is laid out like:


The Radio Gateway, in the above picture, is what is running the software I have written. Within this node, the software is related to itself in the following way: 



This setup was successfully demoed in class. I am planning on creating a video demonstration at some point, but it might have to wait a few weeks.

Here is a sort of cluttered image of the setup:



PS- If anyone wants the source for the diagrams above, feel free to ask for them. I was originally going to post all GraphViz sources to GitHub gists, but I don't know how useful they are to anyone else, and I don't really want to clutter my gists.



SparkFun Video Captioning [Part 3]

And another one gets pushed up. This time I decided to look in the Fedora repos for a subtitle editor. I found two, and for this one, I decided to uses gnome-subtitles. It's pretty good. It takes care of all of the formatting, the time code manipulation, etc. The key bindings aren't the best though.

SparkFun Video Captioning [Part 2]

I just submitted a new pull request for a SparkFun video caption file. I feel this work is relatively easy, long and tedious sometimes, but easy. Definitely a positive: my typing speed is improving.
