Trevor King Date: Thu, 24 Oct 2013 16:36:33 +0000 (-0700) Subject: modular/shell: Start reorganizing the shell material X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=HEAD;p=swc-modular-shell-hearing.git modular/shell: Start reorganizing the shell material Mostly split the examples out into their own directories with READMEs, but there was a lot of editing to partially convert the long-form notes into a condensed instructor.md targeted at instructors. I've gotten to the pipes section and run out of steam. Erik may be taking over the rest of the rewrite... W. Trevor King: I dropped everything from the original 7ba5e9d except for the modular/shell/exercises/hearing/README.md addition. I also merged in the history of the shell notes from git://tremily.us/swc-modular-shell master so you can follow the development of the README content. --- ba16a2adb60b3e5f09804d79843a3078b98cef0d diff --cc README.md index 0000000,0000000..61d5fda new file mode 100644 --- /dev/null +++ b/README.md @@@ -1,0 -1,0 +1,36 @@@ ++# Cochlear Implants ++ ++A cochlear implant is a small electronic device that is surgically ++implanted in the inner ear to give deaf people a sense of ++hearing. More than a quarter of a million people have them, but there ++is still no widely-accepted benchmark to measure their effectiveness. ++In order to establish a baseline for such a benchmark, our supervisor ++got teenagers with CIs to listen to audio files on their computer and ++report: ++ ++1. the quietest sound they could hear ++2. the lowest and highest tones they could hear ++3. the narrowest range of frequencies they could discriminate ++ ++To participate, subjects attended our laboratory and one of our lab ++techs played an audio sample, and recorded their data—when they first ++heard the sound, or first heard a difference in the sound. Each set ++of test results were written out to a text file, one set per file. ++Each participant has a unique subject ID, and a made-up subject name. ++Each experiment has a unique experiment ID. The experiment has ++collected 351 files so far. ++ ++The data is a bit of a mess! There are inconsistent file names, there ++are extraneous `NOTES` files that we'd like to get rid of, and the ++data is spread across many directories. We are going to use shell ++commands to get this data into shape. By the end we would like to: ++ ++1. Put all of the data into one directory called `alldata` ++ ++2. Have all of the data files in there, and ensure that every file ++ has a `.txt` extension ++ ++3. Get rid of the extraneous `NOTES` files ++ ++If we can get through this example in the available time, we will move ++on to more advanced shell topics…
