Things You Can Do With Windows Notepad

 Windows Notepad is the barest of bones plain text editor you can get for Windows, and that’s why so many of us love it or hate it. Notepad has been bundled with Windows ever since Windows 1.0 launched in 1985, and it’s evolved only slightly. But after decades of use, there are a few groovy features hidden in Notepad that you may have never known existed. Check ‘em out...


Insert the Time and Date
Press F5 or choose Edit and Time/Date to automatically insert the time and date into Notepad. Handy for all those captain’s logs you’ll be keeping on your next starship journey.

Switch to Right-to-Left Reading Order
Right-click in Notepad and choose Right to Left Reading Order to change the way the text is displayed. This is useful if you’re typing in a language that is read from right to left, such as Arabic or Hebrew. As you’ll notice from the screenshot, it only reverses the order of the letters and words if you are actually typing in a language that reads from right to left. For English and other left to right languages, it arranges it much as if it were right-aligned, except the punctuation ends up on the left side of the line.

Insert a Timestamp Each time a File is Opened
Create a new .txt file and at the very top on the first line, insert: .LOG. Now, whenever you open the file in Notepad.exe, Notepad will automatically insert a timestamp on the next line. This is handy if you have scripts or other automated network tasks where a log file is created.

Customize the Header and Footer in Notepad
Notepad doesn’t have the rich text editing features of bona fide word processors, but you can still add a header and footer to each page for printing. To do so, click File and choose Page Setup. Here, you’ll see the Header and Footer boxes. You can enter plain text here, or special characters which automatically insert the date, time, page number and other information.


See the chart below for the special characters you can use in Notepad headers and footers:

Go To a Specific Line
Press CTRL-G or click Edit and choose Go To… to jump to a specific line in the text document. Note that you must have Word Wrap turned off (click Format and choose Word Wrap) for the Go To… feature to work.


You don’t need to number your lines in order for this to work, and if you do, Notepad will just go by its own numbering, with the first line number as 1, the second as 2 and so forth. This might be helpful if you’re using Notepad.exe to code or script, and your browser spits out an error such as “Syntax error on Line 642.” You can then open up Notepad.exe, hit CTRL-G and type in 642 and automatically be taken to the offending line of code. That’s much easier than counting them by hand.


Also, note, that when you first hit CTRL-G, the number in the field will be the current line number, which his helpful for keeping track of where you are in your text document. You can also see the Line and Column number by clicking View and choosing Status Bar.

Conclusion
So, there you have it—Notepad does more than you thought it could. While this might not elevate it to the full-featured level of programs like Notepad++, these tips can save you some time if you prefer to stick with good ol’ Notepad for your plain text editing endeavors.

What is a Dual Core Processor

A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It's the equivalent of getting two microprocessors in one.

In a single-core or traditional processor the CPU is fed strings of instructions it must order, execute, then selectively store in its cache for quick retrieval. When data outside the cache is required, it is retrieved through the system bus from random access memory (RAM) or from storage devices. Accessing these slows down performance to the maximum speed the bus, RAM or storage device will allow, which is far slower than the speed of the CPU. The situation is compounded when multi-tasking. In this case the processor must switch back and forth between two or more sets of data streams and programs. CPU resources are depleted and performance suffers.

In a dual core processor each core handles incoming data strings simultaneously to improve efficiency. Just as two heads are better than one, so are two hands. Now when one is executing the other can be accessing the system bus or executing its own code. Adding to this favorable scenario, both AMD and Intel's dual-core flagships are 64-bit.

To utilize a dual core processor, the operating system must be able to recognize multi-threading and the software must have simultaneous multi-threading technology (SMT) written into its code. SMT enables parallel multi-threading wherein the cores are served multi-threaded instructions in parallel. Without SMT the software will only recognize one core. Adobe® Photoshop® is an example of SMT-aware software. SMT is also used with multi-processor systems common to servers.

A dual core processor is different from a multi-processor system. In the latter there are two separate CPUs with their own resources. In the former, resources are shared and the cores reside on the same chip. A multi-processor system is faster than a system with a dual core processor, while a dual core system is faster than a single-core system, all else being equal.

An attractive value of dual core processors is that they do not require a new motherboard, but can be used in existing boards that feature the correct socket. For the average user the difference in performance will be most noticeable in multi-tasking until more software is SMT aware. Servers running multiple dual core processors will see an appreciable increase in performance.

Multi-core processors are the goal and as technology shrinks, there is more "real-estate" available on the die. In the fall of 2004 Bill Siu of Intel predicted that current accommodating motherboards would be here to stay until 4-core CPUs eventually force a changeover to incorporate a new memory controller that will be required for handling 4 or more cores.
