If you are a programmer, you  might experience on saving your different ftp , email , website credintals (usernames and passwords) . Someone uses google documents for saving passwords. Some use email itself as a password storing medium. To be more secured, you have to save your passwords in you local machine rather than putting them into any other 3rd party online medium.

Truecrypt is an open source software for saving secured data (Folders and files). It is available for most of the operating systems (Windows, Linux, Mac etc). The advantage of TrueCrypt is, it creates a seperate partition or storage device as a normal USB memory stick. When you mount the partition it asks for a secured password. You can save your personal and secret files inside this partition. You can creates more than on partition using this software. So you can seperate your data files if you needed.

Here is the website url: http://www.truecrypt.org/

It also provides two level security. It adds a hidden file inside another secured file, so that when an adversary forces you to reveal your password, or forces you to open the secured folder, there is no chance for them to view the hidden encrypted file.

For more details visit:

In some cases, if you are in between any work of editing or typing a content, and you wont let the visitor to navigate away from the page without particular condition, say the document is not saved yet, you can block the navigation (even the closing of the browser window) with Javascript.

Here is the javascript code for that:

<script>

window.onbeforeunload = function (evt) {
var message = ‘Are you sure you want to leave?’;
if (typeof evt == ‘undefined’) {
evt = window.event;
}
if (evt) {
evt.returnValue = message;
}
return message;
}

</script>

Just paste this code anywhere in your html page. The condition settings , warning messages are up to you. In the above code, the warning will be displayed when ever a navigation happen (Even closing of browser window happen)
