How to Make Documents Read Only inside Word 2007

In previous versions of Office, to make a document read only, you need to right click, select properties and make the document read only. But Office 2007 has a built in feature inside word to make the document read only. The advantage of using the feature is that once the document is made read only, ribbon features are also disabled. To make a document read only, click on the office button on the top left corner and select Prepare. Inside prepare menu, you will be able to see the option, Mark as Final.

Once you select the option, you get a pop up confirming that the document will be saved and made read only.

Once the document is made final, you get a message that status property is set to final and typing and editing commands are turned off.

Now you can see that the ribbon features will be disabled and document cannot be edited, if you want to bring back the document to write mode, select Mark as Final option once again from the prepare menu.

How To Automatically Shut Down Your Windows XP Computer

It’s been said, “Not owning a computer is the most secure computer.” While that’s true, we need to take steps to keep our computer secure.
As a general rule, I like to shut my computer off when I’m away from it for long periods of time. That includes going out for the day or night, as well as going to sleep. Sometimes it’s hard to remember to shut it off. So in this article I’ll show you a way to shut your Windows XP computer off automatically.
Windows XP comes with a program called shutdown.exe and is located in your system32 folder which typically resides under C:\Windows or the main folder where Windows XP was installed.
So let’s set this up quickly:
1. Go to “Start->Control Panel” and click on “Scheduled Tasks” if you’re in “Classic View”. If you’re not in “Classic View” you are probably in “Category View”. In “Category View” you’ll click on “Performance and Maintenance”. Then click on “Scheduled Tasks”. You’ll see the following screen. Double-click the “Add Scheduled Task” icon.


2. Click “Next” on the “Schedule Task Wizard” screen (below).

3. Click the “Browse” button on the next screen that lists the different applications you can select from (below).

4. Browse to C:\Windows\system32 and select the program shutdown.exe (below).

5. After selecting shutdown.exe, select “Daily” for “Perform this task:” (below).

6. I sleep during the night. That’s why I shut my PC down automagically at 3:00am (below). But, I run some jobs automatically at 1:00am – virus scan and spyware scan, which will be part of a future article. Feel free to adjust this time to fit your schedule.

7. You’ll be asked to provide a user name and password that will be used to run this task (below). Warning: If you don’t know your password, that ok. You can add or change it later. If you don’t provide the correct password, you’ll get an error screen after this step. However, you’ll still be able to finish this process.

8. At this point you’ve successfully added a new schedule task to run at 3:00am. However, let’s click on the “Open advanced properties fro this task when I click Finish” checkbox and click “Finish” so we can add some command line parameters to shutdown.exe (below).

9. You’ll be presented with the following screen.

10. Add the following command line parameters as seen below and here – C:\Windows\system32\shutdown.exe -s -t 60 -c “Daily Shutdown” -f. The -s stands for “Shutdown the computer”. The -t 60 stands for “Set timeout for shudown to xx seconds. Feel free to adjust that. You never know when you’re going to be working at 3:00am, so it’s nice to have 60 seconds to prepare for the shutdown. The -c stands “Shutdown comment” which shows up on the screen when the PC is shutting down. And finally the -f stands for “Forces running applications to close without warning”.

11. There’s nothing to change on “Schedule” tab. However, feel free to adjust anything that pertains to your work environment or routine.

12. I also leave the “Settings” tab alone. Again, change what you need to or experiment what suits your work style.

13. This is the final screen (below) that pops up when the task runs. You will have 60 seconds to close applications if you need to.

That’s it!! Now you can rest assured your PC is shut down and half way secure while you’re away from your PC.

What is the world's fastest computer?

To put things in perspective, let's start with the computer sitting on your desk -- the computer you use on a day-to-day basis to browse the Internet, handle spreadsheets, create documents, etc. Most people have something like a Pentium computer running Windows, or a Macintosh. A computer like this can execute approximately 100 million instructions per second. Your particular machine might be twice that fast or half that fast, but that's the ballpark.

The fastest computer in the world is much faster than that, and it is sitting right on top of your shoulders! The human brain is an amazing computing device and the fastest processor available right now. Let me give you an example:
Your desktop computer is just starting to get to the point where it can "understand" speech and take dictation, translating spoken words into written words. It can only understand one speaker, and that speaker has to train it for about 20 minutes, and the dictation software will still make a lot of mistakes. So 100 million instructions per second can barely handle dictation.
Your brain, on the other hand, can understand any number of speakers. It needs no training and will make zero mistakes. It may even be able to understand multiple languages! And the speech processing portion of your brain is just one small part of the whole package -- your brain can also process complex visual images, control your entire body, understand conceptual problems and create new ideas. Your brain is made up of about one trillion cells with 100 trillion connections between those cells. We might take a rough estimate and say it is handling 10 quadrillion instructions per second, but it really is hard to say.
In the 2006 TOP500 list, which ranks supercomputers by speed, the top three supercomputers are as follows:

1. IBM's BlueGene/L - 360 teraflops
2. IBM's BGW - 115 teraflops
3. IBM's ASC Purple - 93 teraflops

Another supercomputer called MDGrape-3, built by the Japanese company RIKEN, has a theoretical maximum speed of 1 petaflop (1 guadrillion operations per second), which is three times faster than the BlueGene/L. But MDGrape-3 can't run the official ranking software of the TOP500 list, so BlueGene/L remains at the top of the list at 360 trillion operations per second, which is pretty fast...but it's still not as fast as your brain.
