Set it by typing..

Making Etherpad content indexable by Search Engines
Etherpad contents very rarely shows up on Search results. But with forums and wikis moving over to it I wanted to find a way to give etherpad a bit of an SEO edge..
Firstly I looked at the twitterstyletags plugin which creates an rss feed or all pads.. This is a perfect solution for a sitemap so that’s that box ticked 🙂
Next I knew that Etherpad served pad contents in an iframe so I looked at better ways to get content for search engines to index. Etherpad includes Read only versions of each pad, these read only versions push the content to the user without displaying it in an iframe so it is a perfect fix for the problem.
My final step will be to find someone to modify the twitterstyletags plugin RSS feed to create a sitemap.xml and to create a plugin that allows users to easily link back from read only versions to currently active pads.
fsc Could not connect to compilation daemon in CentOS
Trying to install etherpad on CentOS and I ran into the fsc issue. Scalac throws a load of errors during compile so that’s a non starter. Interestingly enough even if you change fsc to scalac in comp.sh you still get fsc errors. Even overwriting the fsc binary w/ the scalac binary throws errors..
scala version: 2.8.0 (installed from tar) also tested 2.7.7
Error output:
# fsc -verbose [Server arguments: -d /usr/share/etherpad/. -verbose] [VM arguments: ] [Temp directory: /tmp/scala-devel/root] [Executed command: List(/usr/local/scala/scala-2.8.0.final/bin/scala, scala.tools.nsc.CompileServer)] [Port number: -1] Could not connect to compilation daemon.
selinux is disabled:
# /usr/sbin/sestatus SELinux status: disabled
Paths set as:
# export | grep SCALA declare -x SCALA="/usr/local/scala/scala-2.8.0.final/bin/scala" declare -x SCALA_HOME="/usr/local/scala/scala-2.8.0.final" declare -x SCALA_LIBRARY_JAR="/usr/local/scala/default/lib/scala-library.jar"
/etc/hosts is correct, we can ping localhost:
# ping localhost PING localhost (127.0.0.1) 56(84) bytes of data. 64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.047 ms 64 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.047 ms
Tried fsc -reset to no avail:
# fsc -reset Could not connect to compilation daemon.
Anyone any other suggestions?
Note: I was able to get it to compile the .jar file after a hell of a lot of tweeking and playing around w/ scala_home etc. However fsc still fails/failed. Spent quite a lot of hours on this, would be nice to get a resolution to the fsc issue.
Note: Last time I helped someone with this it was due to the VPS (don’t try to install Etherpad on a VPS) didn’t provide swap space so erm, yeah.. Of course scala and fsc didn’t work properly.. I isolated this by doing
scala -verbose >> logfile.log 2>&1
The error I got was this one which is commonly related to VPS’…
Remember that thing Microsoft demo’d at E3 where you talked to a character on the screen?
Originally Project Natal, now Kinect, part of this new Microsoft tech is certainly opening a new can of worms where managing relationships is the core control of a game.
Best intro ever
Just for fun..
