Tech support tells me to type ‘regedt32′ as opposed to ‘regedit’ to access the registry from the command line (Start > Run). I question the use of ‘regedt32,’ but he says to do it anyway. Whenever I use the registry editor, I recall this incident and never look up the tale of the two regs… until now.

Regedt32.exe is an alternative registry editor available with Windows NT/2000 with features of its own. Regedt32.exe does not support importing and exporting registration entries (.reg) files. Regedit has limitations of its own as quoted here:

“You cannot set the security for registry keys. You cannot view, edit, or search the value data types <>REG_EXPAND_SZ and <>REG_MULTI_SZ. If you try to view a <>REG_EXPAND_SZ value, Regedit.exe displays it as a binary data type. If you try to edit either of these data types, Regedit.exe saves it as <>REG_SZ, and the data type no longer performs its intended function. You cannot save or restore keys as hive files.”

Research indicates regedit has:

• a better search tool
• bookmarking of subkeys
• opens to last edited subtree, export and import capabilities
• all keys are visible from a window similar to Windows Explorer

Regedt32 (pre-WinXP) can:

• run in read-only mode
• allows you to edit values longer than 256 characters (who wants to do that???)
• displays subtrees in their own windows
• modify access permissions to subtrees, keys, and subkeys

In WinXP and Server 2003, the two have been replaced by a new version of regedit that has features from both. Try typing ‘regedit’ and ‘regedt32′ to see what happens. They’re the same. To prove it, while in ‘regedit,’ select ‘edit’ and you’ll see ‘permissions.’ This is a feature that was only available in the old ‘regedt32′ and not ‘regedit.’ Read the rest of this entry »

Link Load Balancing evens out critical resources on data networks with unpredictable requests issued to a server. For example, a web site with heavy traffic may employ two, three or more servers in a link load balancing program. The link load balancing routines enable a network to “juggle” more traffic that otherwise possible If one server is overwhelmed, the link load balancing scheme forwards them to a different server with extra capacity.

Another aspect to link load balancing concerns the communications channels themselves. In this case the “juggling act” is meant to better distribute processing and communications demands more equitably across the network so that no single a computer is overwhelmed by the demand.

Link Load Balancing – Key Features & Benefits
First and foremost is “availability” – 24/7 Application Availability for complete IP Application access. Local and Global Service providers rely on redundancy and link load balancing between servers, WSD units and distributed sites for complete server continuity across global networks

Network Bottlenecks – Link Load Balancing
Network managers are constantly seeking new solutions for eliminating bottlenecks and latencies for the fastest performance of all networked applications and web-enabled transactions. The idea link load balancing technology combines both unlimited application scalability with flexible traffic distribution management of data centers and server farms.

In the world of home ink jet color printing, there is some confusion concerning CMYK color and RGB color. Many photo enthusiasts don’t realize what kind of color space their digital cameras output and are confused when it comes to printing images off of their home ink jet printers. They hit print and wonder why the printed image looks different from what they see on their monitor.

CMYK is the color description representing printed material, short for the colors Cyan, Magenta, Yellow, and Black. Mixing these 4 colors together in different amounts give you the millions of colors that reproduce the colors in printed material. These are actual inks used in printing the images you see in color magazines and books. RGB is the color description for images viewed on your computer monitors, short for Red, Green, and Blue. RGB color is actually light, and mixing different levels of these light colors
creates the millions of colors that come from your computer monitor. All websites and nearly everything you see on your computer monitor is RGB unless the images have been converted to the CMYK color space.

When you print your images on your ink jet printer from your computer, your printer prints the image using CMYK inks. Viewing your image in RGB and then printing it out in CMYK may not yield the results you want. Programs such as Adobe Photoshop will convert your image from RGB to CMYK or vice versa. Some printers require the image to be CMYK before you can print the image correctly. Some printers don’t print the image correctly if the image being printed is in RGB space.

A good reason for printing with a CMYK image is to see your image in CMYK color before printing. When an image is converted to CMYK from RGB, there may be some color changes that are noticeable in the image. The reason for this is because many colors in RGB cannot be reproduced using CMYK inks. That is why it is always a good idea to convert your image to a CMYK color space before printing. You could notice significant color changes to your image, especially in the very intense color areas of your image. Some of these intense color areas may appear less intense or very dull once converted. With photo editing software, you can go in and fix these trouble color areas to your liking.

Many ink jet printers on the market today actually print directly from an RGB color image. And converting the image to CMYK may cause it to print incorrectly. You will need to determine what color space your ink jet printer supports. The packaged software usually will give you a hint regarding color spaces. If there is no option to convert the color space from RGB to CMYK, most likely, the printer will print directly from an RGB color source. Usually, the higher end ink jet printers deal with the CMYK color space as consumer level enthusiasts don’t even know these color spaces exist. New higher end ink jet printers, however, are now printing directly from the RGB color space as there is a wider spectrum of color that can be reproduced in RGB compared to CMYK color.

If you visit the website, Instantimagers.com, the ‘Framers’ and ‘DVD Cover & Disc Art’ designs are provided in both RGB and CMYK color spaces. Comparing the RGB and CMYK images side by side, you’ll notice there are color differences. This is due to some RGB colors not being available as a CMYK converted color. Both versions are provided because not all printers are alike. Some tend to print better with one color space. Many of CMYK printed designs have been manipulated further after conversion to match more closely the colors from the RGB color space as many of the colors in some designs did not covert seamlessly.

Although, the Doubling Cube is unknown to most of the backgammon casual players, it is an essential tool in advanced backgammon strategies and in money matches and tournaments.

This cube is designated for raising the stakes of the match and its introduction to the backgammon world is one of the main reasons for the rise of popularity of backgammon.

The cube has 6 faces and the numbers written on it- 2, 4, 8,16,32,64.

At the beginning of the match, the doubling cube is placed beside the board or on the Bar between the players.

Any player, who feels at any stage of the match, that he is leading sufficiently in the match, before throwing his dice, may suggest to double the stakes by placing the doubling cube with the number 2 facing up.

For example player A decided to raise the stakes.

Player B, his opponent, the player the offer is given to, after reviewing his situation, has two options:

He may refuse the offer and thus lose the game and one unit.

He may agree to double the stakes, and in this case the match continues with higher stakes.

Player B, who agreed to the offer, is now the owner of the doubling cube, meaning only him (player B) has the option to double the stakes again at any stage of the game.

If player B decides to do so, he has to do it on his turn before throwing his dice.

Now he takes the dice and places it so that the number 4 is facing up.

Player A, has now the same two options, only this time if he declines the offer he will lose two units, and if he agrees the stakes will rise to 4 times the original and the doubling cube returns to his control.

The cube can pass from player to player, each time raising the stakes.

The Crawford rule-

If you are playing a game until N- points, and your opponent is leading and reaches N-1 points, meaning he is short one point from winning the game, you are not allowed to use the Doubling cube in the following game, however, you can use the dice in the following matches if the game continues.

The reason is the weaker player will always want to raise the stakes because he has nothing to lose anymore and we want keep the use of the dice in fairness of both sides.

The Jacoby rule-

This rule is used in money games and never in match games. It decides that a backgammon or gammon may not be scored as such only if the cube has been passed and accepted. The reason behind this rule is speeding up.

The Holland rule-

The Holland rule is used in match games and decides that in post-Crawford games, the trailer can only double after both sides have played two rolls. The rule makes the free drop more valuable to the leading player but generally just confuses the issue.

Unlike the Crawford rule, this rule isn’t popular, and is rarely used today.

The beavers, raccoons, otters and any other animals in the backgammon game-

These animals appear only, if wanted by both sides, in money games and never in match games.

If player A, doubles the stakes, and player B believes A is wrong and he (player B) has the advantage, B can double the stakes and keep the doubling cube on his side. For example, if A makes the initial double and puts the doubling cube on 2, B can say “Beaver”, turn the cube to 4 and keep the cube at his side. If A believes B is wrong he can say “Raccoon” and turn the cube to 8. All this time, B remains the owner of the doubling cube. If B wishes to raise the stakes once more, he only needs to say another silly name (the animal’s name is a controversy among players) and so on.

The Chouette-

Chouette is a version of backgammon for more than 2 players. One of the players is the “Box” and plays against the rest of the group on a single board.

Another player is the “Captain” of the group, who throws the dice and makes the moves for the group playing against the box.
