The end of public access to my NSLU2?

orvtech — 2010-03-14T20:01:57-05:00

I just found out that the 'datacenter' where I have my NSLU2 will be shooting down soon. When I say datacenter I mean the house of a friend that have a public IP, this will happen within the next 2 months so I need to start thinking on what to do to keep this site alive and maintained by a NSLU2.

Right now I thing the best option is just to bring it to my house and use it as a backend or publisher and use the VPS as my frontend. I am still contemplating other ideas but I think the easiest option is to just publish trough my NSLU2 and rsync the content to my VPS. My home ISP is u-verse and I dont know how friendly are they about hosting services.

If you have any suggestion please dont hesitate to let me know via twitter ( @m1n1m1 ) or just leave a comment... also if you are hosting any kind of service via u-verse please let me know how has been your experience.

This simple script came from the need of updating my twitter status with the songs that I am playing, the trick is that it will only update my profile if the song has been tagged as 'loved' on last.fm. It will also detect if it is Monday and will add the #mm hash.

twitter_user="<your_twitter_user_here>"
twitter_passwd="your_twitter_password_here"
URL="http://twitter.com/statuses/update.xml"
tags="#lastfm"
lastfm_api="<your_api_from_lastfm_here>"
lastfm_user="<your_lastfm_user_here>"
bit_ly_user="<your_bit.ly_user_here>"
bit_ly_apikey="<your_bit.ly_api_key_here>"

fmtwitted=`cat /tmp/lastfm2twitter.tmp | \
sed -e 's/status=Just played: //g' -e 's/#.*//g' | \
grep '[a-z]'|sed -e 's/\ //g' -e 's/\-/./g'`

fmcurrent=`curl -s "http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&limit=1&user=$lastfm_user&api_key=$lastfm_api" | \
grep -E '<name>|</name>|<artist\ |</artist>' |\
head -n2| sed -e 's/<[^>]*>//g' | tr '\n' '.' |\
sed -e 's/\ //g' -e 's/.$//g'`


lastfm_song_url=`curl -s "http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&limit=1&user=$lastfm_user&api_key=$lastfm_api" |\
grep -E '<url>|</url>' | sed -e 's/<[^>]*>//g' |\
head -n1| tr '\n' '.' | sed -e 's/\ //g' -e 's/.$//g'`
bit_ly_url=`curl -s "http://api.bit.ly/shorten?version=2.0.1&longUrl=$lastfm_song_url&login=$bit_ly_user&apiKey=$bit_ly_apikey" | \
grep shortUrl | sed -e 's/\"/\ /g' | awk '{print $3}'`

today_mm=`date +%A`
if [[ $today_mm == "Monday"  ]] 
  then tags="$tags #mm"
fi


if grep $fmcurrent /tmp/lastfm_loved.tmp  > /dev/null
  then if [[ "$fmtwitted" == "$fmcurrent" ]]
      then exit 0
        else curl -s "http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&limit=1&user=$lastfm_user&api_key=$lastfm_api" | \
	grep -E '<name>|</name>|<artist\ |</artist>' |\
	head -n2| sed -e 's/<[^>]*>//g' | tr '\n' '-' | \
	sed -e 's/^[ \t]*//' -e 's/-/\ -\ /g' -e 's/- $//g' -e 's/\ $//g' |\
	awk '{print "status=Just played: "$0}' > /tmp/lastfm2twitter.tmp
	lastfm2twitter=`cat /tmp/lastfm2twitter.tmp; 
	echo $bit_ly_url 
	echo $tags | tr '\n' ' '`
	echo $lastfm2twitter > /tmp/lastfm2twitter.tmp
	curl -s -u $twitter_user:$twitter_passwd -d @/tmp/lastfm2twitter.tmp $URL > /dev/null
	  fi
	  else exit 0
fi

As you can see I am using bit.ly to shorten the urls of the song, you will need a bit.ly API for this to work. I think what is left is to optimize the script storing the curl requests in a file sort of like a cache and add a routine to detect if it is longer than the 140 charaters allowed by twitte and shorten the text to be posted as the status.r
