Tooth Paste – more uses than you think
Tooth paste is meant for cleaning teeth, but the nature of toothpaste and the chemical composition makes it a very useful product for many other purposes. I would like to share some of unusual applications of toothpaste.
| 1 | Remove Crayon Marks So the children have made your walls,floor or furniture dirty with crayon! Can’t afford chemicals to clean the  place? Don’t worry, there’s a simple solution. Squirt a small dab of non-gel toothpaste on the area where the mark is. Rub gently with a soft cloth. Now rinse with warm water. Viola! All gone. |
| 2 | Deodorize hands Are you trying to get rid of that strong odor of onion and garlic off your hands? Wash them with a blob of toothpaste. |
| 3 | Whiten Sneakers Afraid of using bleach liquid to whiten your sneakers? Clean the rubber soles with an old tooth brush and non-gel toothpaste. |
| 4 | Buff a DVD So you weren’t so caring for your DVDs. After a couple of use you got scratches on the DVD. Squeeze a little non-gel toothpaste on the DVD starting from the centre out to the edge. Rinse with water and dry with a non abrasive, lint free cloth. |
| 5 | Defog Goggles  Apply a coat of toothpaste inside the swimming goggles, then wipe off. They will be crystal clear. |
Cut your costs. Go green!
THE REVOLUTIONARY OS
In a time when compute industry was completely monopolized, computer Os were expensive. A group of computer programmers came up with an idea of a free OS. The philosophy behind this idea is RICHARD STALLMAN, the founder of the GNU project. The author of “Open source” definition is BRUCE PERENSE. The Author of Linux kernel when it was first released is LINUS TORVALDS.

ACCESS ADITA VPN FROM ANOTHER PC
A lot of users ask how to access their PC from another PC. It’s really simple. Follow these steps.
1.Add the VPN Port (default is 443) to the exception list of your firewall in order to allow incoming connections to that port.
2.If you are behind a router you will also need to forward the VPN port to your PC (Where the VPN Server is running).
3.Now find your IP address as seen to the internet by visiting www.cmyip.com. To access the VPN, point the browser to http://your-ip-here. If your IP is 123.176.10.30 then point your browser to http://123.176.10.30 .
If you have a dynamic IP address things become a little complicated. Every time your dial your ISP a new IP address is assigned to your PC. Fortunately there is a free service called DynDNS.
Free SSL Virtual Private Network
Some guys might wonder "What in the world is VPN?". Don't wory, if you have no idea what a VPN is goto www.wikipedia.com and spend some time reading the article. Basically a VPN is used to access resources in a LAN from a Computer Outside the LAN. VPN's are also used to connect two LANs together. How about accessing your PC from office? After you Install and configure VPN on your home PC, all you need is an internet connection and a web browser to access your PC from any location.So lets setup a FREE SSL Virtual Private Network.
What you need?
1- Open VPN ALS can be downloaded from www.sourceforge.net . But there's no official Windows installer. It'll be cumbersome to install and configure it manually. So I recommend downloading a third party Windows Installer for Open VPN ALS. Get it here.
You'll need to install the Java Runtime environment first, before installing the software.
2- Java Runtime Environment from http://www.java.com/getjava/
Are you sure your passwords are safe?
In a recent visit to the headquarters of a local news paper I found that some computers has spying software installed. Are you sure your office computer is safe?What is a Keylogger?
Keyloggers are software or hardware tools that captures or stores whatever you type on the keyboard. It captures everything including your passwords, your chat logs and whatever you typed on the keyboard. Some modern keyloggers have the ability to capture the screen as well. There are two types of keyloggers; software and hardware.
The Solution
If you have administrator rights install an anti-keylogger software to remove all keyloggers.
Alternatively you can use this tool to temporarily disable keyloggers. I also reccommend you to try these tools which are listed in wikipedia and roboform2go which is a password management tool for websites.
Confuse keyloggers when you enter a password.
Example: your password is 'thesecretpassword' .
- Type 'the' in the password box
- Click on the browser address bar or open the notepad and type something else
- Again put the focus to the password input box and type 'secret'
- Click on the browser address bar or open the notepad and type something else
- Again put the focus to the password input box and type 'pass'
- Click on the browser address bar or open the notepad and type something else
- Again put the focus to the password input box and type 'word'
