How to hide extensions for known filetypes

The age of wireless computing has brought unprecedented freedom and mobility for computer systems users in a variety of circumstances. These days wireless networking products are so ubiquitous and inexpensive that just about anyone can set up a WLAN in a matter of minutes with less than $100 worth of equipment. This widespread use of wireless networks means that there may be dozens of potential network intruders lurking within range of your home or college dorm or office WLAN.

The risks

Wireless networks don’t stop at the walls of your home. In fact, wireless networks often extend more than 300 feet from your wireless router. If you live in an apartment, dorm, or condominium, you may have dozens of neighbors who can access your wireless network. If you live in a house, your neighbors and even people on the street may be able to connect to your network.

It’s one thing to let a neighbor borrow your lawn mower, but you should think twice about allowing anyone to access your home network. There are several good reasons for this. People who can connect to your wireless network might be able to:

a. Slow down your Internet performance

b. View files on your computers and spread dangerous software

c. Monitor the Web sites you visit, read your e-mail and instant messages as they travel across the network, and copy your usernames and passwords

d. Send spam or perform illegal activities with your Internet connection

By setting up security features on your wireless network, you can make it very difficult for uninvited guests to connect.

Wireless networks are becoming increasingly popular, but they introduce additional security risks. If you have a wireless network, make sure to take appropriate precautions to protect your information.

Gmail tips and TricksGoogle’s GMail is one of the dominant free email providers on the internet along with Microsoft’s Hotmail and Yahoo! Email. However, GMail is more popular in the scientific and the current student community which grew up with computers and technology.

If you don’t have a GMail account, I would highly recommend that you open one right now. You can use all your fancy nicknames with Hotmail and Yahoo but I would recommend a [email protected] email. I mean when you graduate and sending out resumes to potential employers, you want your email to be [email protected] and not [email protected]

Yahoo mail and Microsoft Outlook

You can use Microsoft Outlook with many email accounts. Most Email providers such as Google’s Gmail, Microsoft’s Hotmail and many other providers provide free POP and SMTP access which allows you to use and integrate all your Email Accounts using Microsoft’s Outlook Express. The only exception is Yahoo’s Yahoo! Mail. In this day and age it is really unfortunate that Yahoo does not provide free POP and STMP access to the users of its free Yahoo! mail.

Note: Yahoo does provide free POP and SMTP access to its premium Yahoo! Mail Plus which requires a paid subscription. If you are one of those who has a Yahoo! mail Plus account, scroll down to the bottom of this article on how you can access Yahoo! Mail using Microsoft Outlook.
