Is using WEP or WPA encryption for my Wireless Network is Safe ? wireless security tips

Posted: 17 May 2010 12:20 AM PDT

One of my friend purchased a brand new Wireless Router and asked the help of their customer support to setup the wireless device. The technician on the other side was courteous enough to setup this wireless with a strong wireless key. Later he discussed with his friend, about the service he got from the wireless technician, he inquired which wireless encryption they set on the wireless router. My friend is not good in wireless so he said it is a ten digit number which is used as wireless key. His friend said he should change the current encryption as it is very easy to break and sneak in to his wireless network. So he asked me why his friend suggested him to change his wireless key.

He is using WEP 64 bit (Wired Equivalent Privacy) encryption on his wireless network as its wireless key is 10 digit alpha numeric key (ie: 1 to 9 and A to F ).

Is it recommended to use WEP on your Wi-Fi ?

WEP is the basic wireless encryption available now with high wireless performance and least wireless security. If you are really concerned about the security of your wireless network, you should not use WEP as your wireless encryption. It is proven that WEP is easy to break using small freebie software available in Internet. Using WEP 128 bit encryption is better than WEP 64 bit encryption but I recommend you to start using WPA (Wifi Protected Access) for your wireless network.

Secure your wireless network from hackers

WEP or WPA which is better or both are vulnerable ?

If you are worried about the security of your wifi network , WPA is far far better than WEP. It is heard that even WPA network is hacked in an experiment done by certain wireless security specialists. So what they suggest is forget about WEP and WPA.. if you really concern about security , upgrade your wifi security to WPA2 at-least. So in the hands of a crooked minded wifi hacker both WEP and WPA are useless.

Protect your Computer from overheating -keep PC cool

Posted: 16 May 2010 03:00 AM PDT

I am writing this post regarding the over heating of computer due to my today's experience. My computer suddenly stop working and shut down immediately. At first I wondered what is the reason behind this and I restated my computer. When my computer restarted it showed me the previous shutdown was due to processor over heat. Due to the over heating issue my computer shutdown immediately to avoid further damage.


Reasons for Computer Overheating issues




The major reasons for processor overheats are :

1. CPU fan failed to work

2. Heat sink issue

3. Dust inside the cabinet

4. Flow of hot air from cabinet blocked

5. PC Overclocking


If there is any heat related issues happen in your computer, at first place we should check your cabinet fan and processor fan. If the fans in your computer cabinet is not working properly, it can increase the temperature inside the CPU.

Another reason is heat sink may be not doing its job properly. Heat sink is the device which is designed to remove over heat from processor to surrounding air and keep the processor cool. The dust inside the cabinet can indirectly increase the temperature inside your computer cabinet. It can reduce the speed and functionality of your computer fan.

Another major reason for CPU overheating is the denial of free flow of hot air from your computer cabinet. This can increase the temperature inside your computer cabinet. PC overclocking too can increase the temperature produced by your CPU.

Solutions to avoid PC overheating issues

The first step we should do is to check whether the fans in your cabinet are working properly or not. If there is any issue with fans, change the fan immediately. Changing heat sink and revert back overclocking are other options to reduce computer overheating. Always make sure that hot air flow from your computer is not blocked by surrounding materials. If there is any dust inside your cabinet, clean that.

If there is any wireless filter set on your computer to prevent your computer from connecting to a specific wireless network, you can remove it from command prompt itself. The syntax for the command to delete filter from your computer is:

netsh wlan delete filter permission={allow|block|denyall} ssid=NETWORKNAME networktype={infrastructure|adhoc}

Let us see how we can use this command to delete already created wireless filter from our computer.

First of all we should check whether any wireless filter enabled in our computer or not by typing the following command on command prompt.

netsh wlan show filters

Show already created wireless filters in my computer

If the Wireless AutoConfig Service is not running on your computer, it may show some error message. To enable this service click on the link below.


Start wlansvc (Wireless AutoConfig Service) on your computer

Now we can type the command to delete this wlan filter enabled in our computer.

netsh wlan delete filter permission=block ssid=siju1 networktype=adhoc

Please make sure that your command prompt is running as administrator to run this command. Steps to start your command prompt as administrator are:

Run command prompt as administrator

Now:

The Futures of Camera

The Futures of Camera

The Futures of Camera

Posted: 14 May 2010 09:33 PM PDT

Since the images that a digital camera captures is in electronic form, it is a language recognized by computers. This language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you took. like any conventional cameras, a digital camera is furnished with a series of lenses that focus the light and creates the picture that you require to capture. The difference here is then; a conventional camera focuses its light on a film while a digital camera focuses the light in to a semiconductor gizmo that electronically records the light. Recall the built in computer, it comes in here and breaks this information to digital information resulting to all the features of the digital camera.

Basically a digital camera is a deice use to capture pics without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes. It's a built in computer and records the images it captures in an electronic form. Having and operating three does not even require the use of electricity.

A collection of tiny diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of the electrons gathering will be larger

Another feature of the digital camera is that it's a sensor that converts light in to electrical charges. A charge coupled gizmo or CCD is an picture sensor that is found in a digital camera. While other low-end digital camera use complementary metal oxide semiconductor or CMOS as an picture gizmo, it can still become better and more famous in the future but most engineers are do not believe that it can replace the CCD for higher-end digital cameras.

The price of a digital camera nowadays have been depreciating, three of the main reasons of this is because of the introduction of CMOS picture sensors, this is because CMOS sensors are less costly and are less hard to manufacture than CCD sensors. A CCD and CMOS sensor works the same way at first, by converting the light electrical charges in to photosites. Basically putting it, is to think that a digital camera works in such a way as thinking that the millions of tiny solar cells, each of which forms a part of the whole picture. Both CCD and CMOS do this task using different methods.

When shopping for the best digital camera, take note of these key features.

Lens. Select a digital camera with better digital zoom. The digital zoom of the camera will enable you take the pixels from the picture sensor and incorporate them to make an picture.
Power. Always opt for rechargeable batteries, they can always come in handy, and you don't waste as much money on the disposable ones.

Picture quality. Check the resolution of the camera. The higher the resolution, the more thou will be able to enlarge your picture without the grainy or the out-of-focus effect that they all require to keep away from.

Options. So you can brag to your friends how nice a photographer or artist you are. Or select the three that gives options that best cater to your lifestyle, so you won't ever whine how you never get the right pics.

Memory. If you're a photo freak, be sure that you have memory in your camera to take all the wacky, freaky, funny and any photo you can. Think 512MB if you're a photo junkie and takes pics of anything.

Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer program is, you don't require to go jogging around the whole state or the country looking for a computer that's compatible with your digital camera, wont you?!

Physical. If you are going to be bringing it everywhere, select a handy and portable digital camera. This way, it won't always feel as heavy and bulky as those cameras that you see professional photographers are always dragging on their neck. Don't they ever get tired of that?!

These are the basic things you must look for in a digital camera when you buy three. A digital camera is so great that it is quickly replacing all conventional cameras in the market, with all its technology and portability, truly the digital camera is the future of cameras.

Google says mistakenly got wireless data
Alexei Oreskovic, 5/14/10

"Google Inc said its fleet of cars responsible for photographing streets around the world have for several years accidentally collected personal information -- which a security expert said could include email messages and passwords -- sent by consumers over wireless networks....Google did not specify what kind of data the high-tech cars collected, but a security expert said that email content and passwords for many users, as well as general Web surfing activity, could easily have been caught in Google's dragnet."
