Learn How To Type Faster on a Keyboard

Learn How To Type Faster on a Keyboard
Most of us use two fingers of each hand to type on a keyboard, in this tutorial you will learn how to type faster on a keyboard. You will memories every key on the keyboard, you will type faster while looking at the screen by using the correct fingers, and gain speed.
Typing faster can enable you to keep up with your brain; that little voice in your head that has great ideas might only last for a few seconds before it’s forgotten.

Use All your fingers while typing:

Most people have the bad habit of typing with two fingers only, while they can use 10. If you take a closer look at your keyboard, you’ll notice raised bumps on each of the F key and J key. This is to help you find the correct finger placement without having to look at the keyboard.
Place your fingertips on your keyboard, as in the picture. This is the basic position for touch typing. You can find this position without even looking at the keyboard (feel the bumps). You can be fast without this position but you will not exceed 30 words/min, while with your 10 fingers, you can reach the speed of 180 words/min and more.
Learn How To Type Faster on a Keyboard

Learn to type faster without looking at the keyboard:

After you get the right position, familiarize yourself with the keyboard, many websites can help you for this step, websites as Keybr.comTouch Typing Study, or many others… I personally used sense-lang.org. As a beginner, this website will help you to memories every letter on the keyboard. When you get to lesson 16, you will be typing words and sentences that have meaning. Typing sentences that have meaning is very important for you to be successful !
By practicing 30-60 minutes a day, after one week, you should be able to type 40 words per minute without looking to the keyboard. And this is only the beginning.

How to Test your vision online

Are you working daily on your computer and you want to test your eyesight?
ThinkQuest is an online tool to test your vision at home for free. This allows you to test your eyesight through a succession of letters becoming small. A bit like a doctor!
test vision Eyesight test online

To take this test the application will ask you to choose the size of your monitor (you must have either a 15″, 17″, or 19″ monitor), and your screen resolution, to measure out the correct length that you should sit back at (the length will vary depending on your screen size and resolution).
Now read the row of letters on the screen and press “next” to display more rows in decreasing sizes. When you can no longer read more than half the words on a line, press “stop” and you will get the result.
Of course this self eye test is no substitute for visiting your doctor but if you follow the steps well, you may get some idea about how good (or bad) your vision is.

ZenMate: Chrome extension for Free VPN with easy location switching

In a previous post we've learned What is a VPN and How does it work ? VPN is a network technology that creates a secure network connection over a public network such as the Internet.

ZenMate is a free extension for Google Chrome that will allow you to get a free VPN. A service that lets you connect anonymously and access sites that are blocked or censored in your country! Unlike other Chrome extensions – which are usually regular proxies without encryption - ZenMate will encrypt your browser traffic and build a secure tunnel around the data you send or receive. Your IP is hidden, your Internet unrestricted and your privacy protected.

ZenMate change ip location openhow



How to use ZenMate and Change your IP:

Once you have installed this extension, a shield icon appears on the top right of your browser and you will be redirected to a new page that will ask you to enter you email to activate ZenMate. Then you will have a message saying that they “have sent you an eMail with your account credentials but you’re already signed in and can surf the web protected right away!”.

To access settings just click on the shield icon on the top right of your browser, to turn ON/OFF the service, (ON: the color of the shield turns green), you can even choose your location by clicking on “Change location”. ZenMate secure your connection and lets you access restricted content that only works in some countries such as Hulu.com or Pandora.com which only works in the USA, by changing the IP address location.

Download ZenMate for Google Chrome for free.



Note! The VPN is NOT a way to increase its anonymity for prohibited practices. A VPN does not make you completely anonymous and invisible !. It’s a way to protect your Internet privacy.
