======Part 3====== =====Entries===== ====Entry 1: November 2, 2012==== Today I popped an old hard drive into foxtrot, to see if anything was important in there. After installing and turning it on i quickly realized that the drive was old and bad. But I do not want to unplug it now because I am working. Wedge has notified me of the command hdparm. Reading into the man page, the -y appendage sends the drive into a shutdown state. Excelent. I needed to point it at the drive "/dev/sdb" using sudo rights of course. The command was "sudo hdparm -y /dev/sdb" ====Entry 2: November 19, 2012==== Today I am studying multi-threading within a computer and how it handles more threads then the general time-division multiplexing. The difference appears to be that in multi-threading, each core handles it's own thread. Whereas in time-division multiplexing only effects one thread at a time. ====Entry 3: November 20, 2012==== Today Pressly asked for a little help from me today involving some [DATA COMMUNICATIONS] stuff. He had configured a router to bridge connections from ethernet and also wireless connections. From there, we connected my macbook via ethernet to his router. From his computer [192.168.10.100] we pinged my computer [192.168.1.100]. This table can be shown using netstat -nr. ====Entry 4: November 28, 2012==== After talking about it for so long, On Friday we are about to partake in cleaning the cage by putting things into boxes. This is going to teach us many things that we overlook everyday. Cards that we never knew worked from old suns and pcs. =====Keywords===== {{page>datapart3&nofooter}} {{page>datacommpart3&nofooter}} {{page>hpc1part3&nofooter}} =====Experiment 3===== ====Question==== Can I stream music from one computer to another using commands ====Resources==== Google Wikipedia http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&sqi=2&ved=0CDAQFjAA&url=http%3A%2F%2Fwww.videolan.org%2Fdoc%2Fstreaming-howto%2Fen%2F&ei=CcC8UIDgFZO30QHVq4G4DQ&usg=AFQjCNGA25CyF7j3BlA0-aEl0TqxNxcx1g&sig2=VMSnSLlDnBvlLVfh-7q9lQ http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&sqi=2&ved=0CEUQFjAC&url=http%3A%2F%2Fwww.engadget.com%2F2005%2F11%2F29%2Fhow-to-stream-almost-anything-using-vlc%2F&ei=CcC8UIDgFZO30QHVq4G4DQ&usg=AFQjCNHGShJygvCAeXSgZU59mDriTftecA&sig2=wQnAn8_7TzbSxlFLIohe0w ====Hypothesis==== Using vlc, I should be able to stream music over the network and pick it up on another machine ====Experiment==== I gots me two machines to use and im finna stream some music using vlc. ====Data==== Perform your experiment, and collect/document the results here. ====Analysis==== After several unsuccessful tries with udp, I had to mess with the configuration of the command i was sending out. I learned that ts=mux is needed for streaming (despite what the GUI tells you). I ended up streaming over http protocol, which gave me better access. The udp packets were all being lost and I have no idea where they were going. The command i used to stream was this: cvlc ~/Music/myheartwillgoon.mp3 --sout '#transcode {vcodec=h264,acodec=mp3,samplerate=44100}:std{access=http,mux=ffmpeg{mux=mp3},dst=0.0.0.0:12345/stream.flv}' This allowed my computer to be set up as a web server for others to access and stream the music live. ====Conclusions==== This wasn't easy to do, but there is quite a bit of documentation on it online. Perhaps in the future this experiment can be enhanced.
