In a large organization, it can sometimes be difficult for the administrator to know whose computer is whose. This little tweak will rename My Computer to "Computername" allowing you to easily see which computer you are logged on to.
Open the Registry Editor (You have to use REGEDT32.EXE) click Start, Run, and type "regedt32" then click on OK to start the regedit utility.
Expand HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}
Rename the value named "LocalizedString" to "LocalizedString.orig". Create a new REG_EXPAND_SZ
value named "LocalizedString", and set the value to "%COMPUTERNAME%".
Exit the registry editor, right click on your desktop and click Refresh. The My Computer icon should now be renamed to "Computername".
Now one only has to glance at the desktop to see what computer they are on.
Not only CON, we cannot create any of these
CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more...
The reason is that con, prn, lpt1..lpt9, etc are underlying devices from the time dos was written. so if u r allowed to create such folders, there will be an ambiguity in where to write data when the data is supposed to go to the specified devices. In other words, if i want to print something, internally what windows does is -- it will write the data to the folder prn (virtually u can call it a folder, i mean prn, con, etc are virtual folders in device level). So if we are able to create con folder, windows will get confused where to write the data, to virtual con folder or real one.
So Now, Try this...
Open the Command prompt by Start -> Run and typing cmd
Creating:
C:\> md \\.\c:\con
Deleting:
C:\> rd \\.\c:\con
Thats all...
How to Access BIOS Setup on Most All Computers
You might want to file this in case you run into a garage sale.........
This is most likely because the particular sequence to enter your systems BIOS
is not by pressing the Del key. There are several key combinations that work and
each system uses their own. When you first power up your computer, view the POST
(Power On Self Test) messages. Typically the message prompting you to enter the
BIOS setup will be displayed soon after the memory check is completed. Within
this message the proper key sequence will be displayed. If you own an HP, Dell,
Gateway or other manufacturer, a "splash" screen may be present that hides the
POST messages. You can bypass this by pressing the Esc or Tab keys to view the
POST messages.

1. Creating screenshots
To get started open up your movie in ImageGrabber (supports wmv aswell) and the movie will start playing. Click the red stop button and the movie is open and ready to go.
Enter the number of screens shots you would like to take of the scene. A good number for a scene is probably about 10-15 and you can have a play around with this and the number of columns explained in the settings below to see what you like.
When you click OK it will go through the movie taking the screen shots and add them to the timeline across the bottom.
You can add individual selected screenshots by using the scrollbar to move to the picture you want and clicking this button to add the current image at the end of the timeline.
Once you have all the pics you want you can arrange the screenshots in the timeline.
* Right click a screenshot to delete it, delete all or change the text label.
* Left click a screenshot to drag it to where you want in the timeline.
ImageGrabber settings
Once you have all the screens you want, on the File menu click Save File and you will see the following default settings dialog box
Layout: Good idea to make the dimensions of each screen (Tile) a fraction of the original to avoid distortion.
Style: Details of the drop shadow around your screens and the background color for your image.
Info: You can include the time each sample was taken in the vid.
JPEG: You can adjust the quality down to reduce the file size say for a full movie with many screens.
Details: You can include the basic movie statistics in the image.
There are plenty of possible configurations, try playing around with different settings until you find a layout you like.
Click the save button and using the Default settings will produce an image with a layout similar to this
01. What is a .mkv file?
MKV means "matroska video" and it is a "extensible open standard Audio/Video container" (AVI is a container, too!). This file format combines several videostreams, audiostreams, subtitles, chapters and information in only one file. It supports new standards like 6-channel AAC (Advanced Audio Coding) audio or x264 video.
02. How to play .mkv files on your computer
First download the Community Codec Pack which can be found here:
http://www.cccp-project.net/download.php?type=cccp
Package with Media Player Classic + addons:

Download the program VSO ConvertXToDVD 2.x! Download with keygen:
http://rapidshare.com/files/81257199/backupaaa.rar
"Working Folder" -> Folder with resulting dvd structure files!
Go through all tabs. Most of the settings are selfexplaining. An important tab is "TV Format"! Set "Video Standard" for your region. "TV Screen" have to be set to "Automatic".
ConvertXToDVD don't support internal subtitle files within .mkv. You need to download the subtitle for your movie from the external subtitle collection (Check below) and put it in the same folder as the .mkv movie file.
Next step: Adding .mkv files with clicking on the green "+":
Check for the subtitles. There should be the entry "1 Subtitle Stream - 0 internal, 1 external". If you double click the movie you get a video preview window.
You are ready to "Convert". You can burn the files using Nero 7.7 and "DVD Video" profile.
04. External Subtitle Collection
Subtitles are included in the .mkv container files of the movies. But there are some players which do not support this. Only use this link if you have problems with the subtitles!

That's it - now you can Netmeet to your hearts content.
If you're a complete novice when it comes to photography, but have a burning passion to learn and have no place to turn to when you're bombarded with jargon, we've got something for you. Here's a list of the most commonly used photography jargon simplified, so that anyone with even the most basic knowledge can understand them. [Article source @ end]
Artifacts
Artifacts are unwanted aberrations caused by sensor, optics or internal image processing algorithms of a camera. The most common artifacts are blooming, maze artifacts, chromatic aberrations, moiré, jaggies, JPEG compression, noise, and sharpening halos.
Aliasing
Ever wondered why diagonal lines appear jagged rather than straight or smooth in some images? This is because of aliasing, which happens due to the square nature of pixels - the minutest component that any picture is made of.
Aperture / f-stop
When you click a photograph, the lens opens to certain degree so that light can pass through it and onto the camera's sensors or film. The size of this opening is referred to as the 'Aperture', and it directly effects the photo's 'exposure' and depth of field.
Aperture Priority
Aperture Priority (also known as Aperture Value and denoted by Av on the camera), is a mode where the photographer selects an aperture value and the camera decides the shutter speed according to lighting conditions, so that you get optimal results. It's different from 'manual mode' which allows you to set both aperture and shutter speed settings.
Aspect Ratio
The aspect ratio of an image is the value of the width of an image/frame, divided by the height of it and denoted in the form of a ratio such as 16:9, 4:3 or 16:10.
Barrel Distortion
Barrel Distortion is a common for of distortion in wide angle lenses where images tend to get 'spherized' or rounded towards the sides. Such distortion is more prominent in images which have many straight lines.
Burst
The "burst" or "continuous" mode allows you to take multiple shots one after the other. The number of shots taken are measured via fps or frames per second, and are different in different makes and models of cameras. To be a little more technical: the fps decides how many times the shutter releases and an image's processed in a second, defining how many pictures are taken in a short span of time.
Depth of Field
The effect generated when the areas on the focal plane (at the focal length) of a camera in a photograph remains in focus (sharp), while other areas stay 'out of focus' (or blurry), is known as Depth of Field. It is enhanced by keeping the aperture small.
Digital Zoom
Unlike optical zoom (which uses a 'zoom lens' that alters its focal length to achieve the desired result), Digital Zoom re-sizes a part of an image digitally in order to fake actually zooming into it.
EXIF
When photos are stored on digital cameras, a lot of additional details apart from the image itself are stored on the resulting file. This data (which is also called Metadata) is stored in the "header" of the file and may include everything from when the picture at hand was take (date, time), shutterspeed, aperture, ISO, and most other settings. This header is usually in the EXIF format (Exchangeable Image File), which was created by JEIDA (Japan Electronic Industry Development Association) as a universally accepted format so that all sorts of imaging devices could access it. This data can be used as a powerful learning tool since you can analyze shots taken by you, check the settings, and decide what settings work best for which type of shots.
Exposure
The amount of light received by the film or sensor of a camera is known as exposure. The exposure of an image can be altered by changing the camera's aperture settings and shutter speed.
Exposure Compensation
Even after selecting an aperture value and shutter speed to fit the lighting of a scene perfectly, an image may be underexposed. In this case the Exposure Compensation (or EV Compensation) found in prosumer and professional level cameras can be tweaked to fix the exposure.
Focal Length
The focal length of a camera (or an eye for that matter) defines the distance from the lens at which objects remain sharp or in focus. In other words, focal length is the distance (in millimeters - mm) between the optical centre of a lens and the focal point.
Histogram
A histogram is a pictorial representation of the tonal distribution in an image. It shows the photographer whether a picture he's clicked has captured all the tonal details or its has areas that have been blown-out due to over-exposure.
