Web and Computer Tech

Hi to All ,A long gap between post but a new topic and refreshing topic..This is hectic month for me to get enough time.But this time I have brought some sensitive stuff and superstitious stuff related with your computer use.

"Do you refresh your desktop?". Ask this to any Windows user and 99% of them will reply with a "yes". Of course, there are various needs for refreshing the desktop but the majority of people who does it doesn't even know why he is doing it. Refreshing the desktop is perhaps the biggest computer myth among all Windows users.

Every single person I have met does this or at least used to do it. It's not known who first discovered this remarkably useless trick and what he achieved from it, but it just spread. Most new users learn this trick from other new users without caring to know what it does. Some do it devotedly just because others do it, while some others have various weird explanations for it. A few of them assumes that it refreshes the RAM, while some others believe that doing it will somehow keep their PCs running smooth and easy. I have seen some users obsessed with refreshing the desktop, doing it every 30 seconds or so. They have even learnt the keyboard shortcut - F5 (just to mention, these are the people who never use keyboard shortcuts). They would press the key and wouldn't release it for a long time, sending the desktop into a frenzy of refreshes.

What does a desktop refresh actually do? Refreshing the desktop simply redraws the icons on the desktop. That's it! It doesn't refreshes the RAM. It doesn't clean your PC. It doesn't refreshes your computer the way it does to you when you wake up from a nap. Refreshing the desktop has absolutely no effect on the working or performance of the computer. So why is the tool there? As I said, refresh is used to re-display or redraw the icons on the desktop. Sometimes when you bring some changes to the desktop icons, the change doesn't get reflected instantly. In such cases, refreshing the desktop becomes necessary to bring the change to effect. Say, you have the desktop icons set to arrange themselves alphabetically on your desktop. When you add a new item to the desktop, this item wouldn't get arranged alphabetically, instead it would appear at the bottom of icon list on the desktop, irrespective of it's name. Now if you refresh the desktop, all the icons would be once more arranged alphabetically and the newly added item would go to it's appropriate position. This is what refresh is for. It is to re-display the desktop. Refresh has the same function when done in explorer. Also Refresh is basically the command used to refresh/reload the video buffer(VGA memory). Sometimes the changes made in the VGA memory are not reflected to the screen properly...Refresh just corrects the prob...

So, if you are in the habit of refreshing the desktop, stop it. You are just wasting your time and effort. And the next time you see a person doing it, don't forget to explain to him the futility of this action

Also, during the times of windows 3.1 - win 95 it was normal for PCs to hang, crash n be restarted every now n then! It looks like even knowledgeable people used the desktop refresh just to get an assurance that the OS is working and not freezing from the resulting flicker of icons.

Today PCs are very stable and crash only once in a blue moon but the habit still continues, and I think for same reason, even I do it sometimes .But friends avoid this habit,this is just waste of time nothing else.

Day was hectic as usual.Work was making me tensed in office......But any how I managed to come home early to surf.After having dinner,I switched on system and open rediff to get today news.I was going through news sudden my eyes goes to this news "The most dangerous web sites for your PC!".I thought ,this will be useful for my readers .

There are many websites which is infected or full of malware or Trojan or virus or make your system to vulnerable or land of hackers.Even myself I got trapped many times to those websites and made my system corrupted or infected and later I had to format system or scan system fully.

Therefore I recommend all of my readers to beware these websites-

An interesting fact to ponder over-Clipboard Hack Problem - Shocking news about CTRL+C

Ctrl+C may be the most important work we do everyday. But it's not a very safe thing to do. Read on to know why. What happens when you press Ctrl+C while you are online. We do copy various data by Ctrl + C for pasting elsewhere. This copied data is stored in clipboard and is accessible from the net by a combination of Java scripts and ASP. This is called clipboard hack problem.

Just try this:
1. Copy any text by Ctrl + C
2. Click the Link: http://www.sourcecodesworld.com/special/clipboard.asp (Interestingly, this hack works only on internet explorer, and not on Mozilla Firefox browser.)
3. You will see the text you copied was accessed by this web page.

Surprised!!!. Do not keep sensitive data (like passwords, credit card numbers, PIN etc.) in the clipboard while surfing the web. It is extremely easy to extract the text stored in the clipboard to steal your sensitive information.

It is true, text you last copied for pasting (copy & paste) can be stolen when you visit web sites using a combination of JavaScript and ASP (or PHP, or CGI) to write your possible sensitive data to a database on another server.

How Cipboard Hack is done?
The Clipboard hack is done by the following Source Code:

<script language="JavaScript">
var content = clipboardData.getData("Text");
alert(content);</script>

• The registry is stored on your computer in several files and depending upon your version of Windows, there will be different files and different locations for these files. When the registry becomes very large, the computer's performance can decrease and cause it to become unstable. Your registry needs to be cleaned if you ever downloaded any files from the Internet. There are tools that help you clean your registry, and you should do this about once a week.
  

We everyday use this small editor but this editor has many hidden features.I like notepad since this is very good editor and easy to use.Do you know that Notepad can be used as a personal diary.Do you want to know to how?Here is how to go about it:

1. Firstly open a blank Notepad file.

2. Now write .LOG as the first line in the file, and then press enter. Now save the file and close it.

3. Open the notepad file now and you will find that the current date and time has been appended (put) at the end and the cursor is in the next line.

4. Type your notes and then save and close the file.

5. Each time you open the file, Notepad repeats the process that is it appends the date and time to the end of the file and places the cursor below it.

This way you can keep track of all your entries, you can easily maintain what you wrote and when. This can work very much like a personal diary.Yo can write your blog post here and keep track when did you write this post.You can manage your all your advertisement ads infy.I found this tips very good and made my work more productive.
