Debian install MailUtils needs configuration of Exim

When you first install MailUtils on Debian

apt-get install mailutils

The system will not send emails.

To test it:

echo "This is the body of the email" | mail -s "This is the subject line" myemail@gmail.com

and have a look at the logs:

cat /var/mail/mail

To fix this, it is needed to configure Exim:

dpkg-reconfigure exim4-config

You will be presented with a setup wizard of something like this:

The settings are pretty straight forward but you can just leave them with Internet Site and type your domain. The rest should work with the default settings.

Adding Placeholder attribute to Tokeninput jQuery plugin

I was having a hard time to get the placeholder attribute to work with Tokeninput jQuery plugin.

First I managed to get it to show up by adding attr(‘placeholder’) to the onReady:
$("#myInput").tokenInput("/url/to/your/script/"){
onReady: function(){ $('#token-input-myInput').attr('placeholder','type here...'); }
};

It worked but every time it lost focus the resize of the input field would partially hide it. So, I tweaked with the code inside jquery.tokeninput.js and after line 436 (declaration of var escaped) added:
if(input_box.attr('placeholder')!=undefined){
escaped = input_box.attr('placeholder');
}

It is not pretty but it works 🙂
