  • This is a quick line to stream in the latest offerings of your favorite netcasts/podcasts. You will need to have a file named netcast.txt in the directory you run this from. This file should have one and only one of your netcast's/podcst's url per line. When run the line grabs the offering on the top of the netcast/podcast stack and end it over , quietly, to vlc. Since I move around computers during the day I wanted an easy way to listen to my daily dose of news and such without having to worry about downloading to whatever machine I am on. This is just a quick grab and stream of whats current. Future plans... have the list of netcasts be read from the web. possibly an rss or such. I use greader so there might be a way to use it as the source so as not to have to muck with multiple lists Show Sample Output

  • This will play the audio goodness posted up on PlayTweets via twitter right form the ever loving cmdline. You do not even need a twitter account. I hashed this out in a bit of a hurray as the kids need to get to sleep....I will be adding a loop based feature that will play new items as they come in...after what your are listening to is over. http://twitter.com/playTweets for more info on playtweets Show Sample Output

  • Pump up the chatter, run this script on a regular basis to listen to your twitter timeline. This is a rough first cut using several cli clips I have spotted around. There is no facility to not read those things already read to you. This could also easily be put in a loop for timed onslaught from the chatterverse, though I think it might violate several pointsof the Geneva Convention UPDATE - added a loop, only reads the first 6 twits, and does this every 5 mins.

    while [ 1 ]; do curl -s -u username:password http://twitter.com/statuses/friends_timeline.rss|grep title|sed -ne 's/<\/*title>//gp' | head -n 6 |festival --tts; sleep 300;done
