This script recursively traverses all HTML elements, looks for input fields and clears their values. It uses only JavaScript. No jQuery required.
// From http://stackoverflow.com/a/1500073/106778
function clearChildren(element) {
for (var i = 0; i < element.childNodes.length; i++) {
var e = element.childNodes[i];
if (e.tagName) switch (e.tagName.toLowerCase()) {
case 'input':
switch (e.type) {
case "radio":
case "checkbox": e.checked = false; break;
case "button":
case "submit":
case "image": break;
default: e.value = ''; break;
}
break;
case 'select': e.selectedIndex = 0; break;
case 'textarea': e.innerHTML = ''; break;
default: clearChildren(e);
}
}
}For posterity’s sake. Source: http://stackoverflow.com/a/1500073/106778. Also at https://gist.github.com/2436981.

This is a slightly modified version of the SFLphone build instructions.
First, install the dependencies:
sudo yum groupinstall group "Development Tools" "Development Libraries"
sudo yum install alsa-lib-devel pulseaudio-libs-devel libsamplerate-devel commoncpp2-devel ccrtp-devel libzrtpcpp-devel dbus-c++-devel pcre-devel gsm-devel speex-devel celt071-devel libyaml-devel cppunit-devel cppcheck
Then clone the master branch because the latest release (1.0.2) has a bug, which prevented me from installing it on Fedora 16:
git clone http://git.sflphone.org/sflphone.git
Compile the PJSIP library
cd sflphone/daemon/libs/pjproject/
./configure && make dep && make clean && make
Install the Daemon core
cd ../..
./autogen.sh
./configure --prefix=/usr
make
sudo make install
Install the Gnome client dependencies
sudo yum install gnome-doc-utils libtool GConf2-devel libsexy-devel libnotify-devel webkitgtk-devel webkitgtk3-devel libgnomeui-devel check-devel rarian-compat
Install the Gnome client
cd ../gnome
./autogen.sh
./configure --prefix=/usr
make && sudo make install

Because the installation of Asterisk via Yum didn’t work out-of-the-box for me, I have decided to install it from source. The instructions to compile and install Asterisk from source from the Asterisk wiki is pretty much straight-forward except for a couple of hiccups, which I encountered. So here is a slightly modified version of their installation instruction that worked for me on Fedora 16:
Install the compiler and system libraries
sudo yum install gcc, gcc-c++, openssl, ncurses, ncurses-devel, newt, libxml2, libxml2-devel, kernel-devel, kernel-devel make
We also need to install SQLite3 in order to avoid seeing this message later on:
configure: WARNING: *** Asterisk now uses SQLite3 for the internal Asterisk database.
configure: WARNING: *** Please install the SQLite3 development package.
So let’s install SQLite3:
sudo yum install sqlite, sqlite-devel
We also need to install doxygen for the Asterisk documentation:
Download, build, and install libpri
Execute the following as root:
wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-1.4.12.tar.gz
tar -zxvf libpri-1.4.12.tar.gz
cd libpri-1.4.12
make
make install
Download, build, install, and start DAHDI
Execute the following as root:
wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-2.6.0+2.6.0.tar.gz
tar -zxvf dahdi-linux-complete-2.6.0+2.6.0.tar.gz
cd dahdi-linux-complete-2.6.0+2.6.0
make
make install
make config
chkconfig dahdi on
service dahdi start
Download, build, install, and start Asterisk
Execute the following as root:
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-10.3.0.tar.gz
tar -zxvf asterisk-10.3.0.tar.gz
cd asterisk-10.3.0
./configure
make menuselect
make
make install
make samples
make progdocs
make config
chkconfig asterisk on
asterisk -vvvvc
Notes: This set of instructions has been tested to also work on Fedora 14 and CentOS 5.7.

First, download the AT&T Global Network Client from ftp://ftp.attglobal.net/pub/custom/ibm_linux/.
If you try to install this using
rpm -ivh agnclient-1.0-2.0.1.3003.i386
you will get an error similar to:
failed to install file:
agnclient-1.0-2.0.1.3003.i386 requires libcrypto.so.4
agnclient-1.0-2.0.1.3003.i386 requires libssl.so.4
To solve this error, create a symbolic link for the missing modules by executing commands similar to this as root:
ln -s /usr/lib/libssl.so /usr/lib/libssl.so.4
ln -s /usr/lib/libcrypto.so /usr/lib/libcrypto.so.4
Proceed with the installation:
rpm -ivh --nodeps agnclient-1.0-2.0.1.3003.i386.rpm
If you try to run it at this point, you will get this error:
The AT&T Global Network Client daemon (agnclientd) is not running. It must be running to create a VPN connection. Please restart your computer or manually restart the daemon.
To solve this, execute the following command as root or just restart your computer:
/etc/init.d/agnclientd start
Note: This instruction also works for Fedora 14, and 15.

Cannot complete the install because one or more required items could not be found.
Software being installed: Subversion Revision Graph 1.0.9 (org.tigris.subversion.subclipse.graph.feature.feature.group 1.0.9)
Missing requirement: Subversion Revision Graph 1.0.9 (org.tigris.subversion.subclipse.graph.feature.feature.group 1.0.9) requires ‘org.eclipse.draw2d 3.2.0′ but it could not be found
If you happen to get this error while installing the Subclipse plugin on Aptana Studio 3, it means you need to install the Graphical Editing Framework Draw2d first, which is not included in the current Aptana Studio 3 package.
Draw2d is part of GEF, which you can get from http://download.eclipse.org/tools/gef/updates/releases/. Draw2d is the first package when you expand the GEF from the menu. No need to install the other items unless you know that you need them for something else.
