Making TeamSpeak 3 work on Ubuntu

 TeamSpeak 3, you can download the Linux client from their site. The only problem is that currently (beta8) the client don't play nice with pulseaudio.

EDIT: Seems like beta-20 is working well with Ubuntu 10.4. Use the ts3client_runscript.sh (make sure you change directory to the TeamSpeak directory first).

After digging in the Ubuntu forums (can't find the exact post link), I came with the following solution:
  • Extract the client (cd /opt && sh ~/Downloads/TeamSpeak3-Client-linux_amd64-3.0.0-beta8.run)
  • Create the following script
#!/bin/bash

# Make teamspeak work on Ubuntu (basically disable pulseaudio before launching)

conf=$HOME/.pulse/client.conf
backup="${conf}.bak"

if [ -f "$conf" ]; then
    mv "$conf" "$backup"
fi
echo "autospawn = no" > "$conf"
pulseaudio --kill

cleanup() {
rm "$conf"
if [ -f "$backup" ]; then
        mv "$backup" "$conf"
fi
    pulseaudio -D
}

cd /opt/TeamSpeak3-Client-linux_amd64/
./ts3client_linux_amd64&
pid=$!
trap "kill -9 $pid; cleanup" SIGINT SIGTERM
wait $pid
cleanup
Good luck! (The other option is to use mumble.)

Multi VCS status

Since I use mercurial, git, subversion and sometimes bzr. I use the following script (called st) to find the status of the current directory.

#!/bin/bash

# Repository status

root=$PWD
while [ "$root" != "/" ];
do
if [ -d "$root/.hg" ]; then
hg status
break
fi
if [ -d "$root/.git" ]; then
git status --untracked-files=no
break
fi
if [ -d "$root/.svn" ]; then
svn status
break
fi
if [ -d "$root/.bzr" ]; then
bzr status
break
fi
root=$(dirname "$root")
done

if [ "$root" == "/" ]; then
echo "error: can't find a repository here"
exit 1
fi

Dynamicall Generating Static Content

Sometimes you want to generate a resource (say a chart) once and then keep it. This way you don't need to keep track of all the objects you've created and can easily clean (since if someone want the resource again it will be generated again).

One way is to do it with lighttpd 404 handlers (view complete code).

lighttpd.conf

# lighttpd configuration file
server.modules = ( "mod_cgi" )

# This is generated by by web-up
include "lighttpd.inc"

server.document-root = var.root
server.pid-file = var.root + "/lighttpd.pid"

# files to check for if .../ is requested
index-file.names = ( "index.cgi" )

## set the event-handler (read the performance section in the manual)
# server.event-handler = "freebsd-kqueue" # needed on OS X

# mimetype mapping
mimetype.assign = (

Enabling Flash on Google Chrom (OSX)

The current release of Google Chrom For Mac has support for Flash, but you need to enable it with the --enable-plugins command line switch.

Here's how to make it persistent (well, until the next update):
[17:31] ~ $cd /Applications/Google\ Chrome.app/Contents/MacOS/
[17:32] MacOS $sudo mv Google\ Chrome _chrome
[17:32] MacOS $sudo gvim Google\ Chrome
[17:33] MacOS $sudo chmod +x Google\ Chrome


And the content of the new Google Chrome is:
#!/bin/bash


"/Applications/Google Chrome.app/Contents/MacOS/_chrome" --enable-plugins $*


Happy surfing ...
