Loose Diamonds: The Round Brilliant And Other Cuts

Why purchase loose diamonds? They're not necessarily as practical as earrings and necklaces. You would not be able to have them on you or display them anywhere you go. But diamonds have a beauty on their own that can't be revealed by diamonds set in jewelry. They seem even more special when they are bought for their own sake.

Diamonds are available in a variety of designs, known in the trade as cuts. The most famous of these is the round brilliant cut. Simply put, the round brilliant is the most popular because it provides the most brilliance. It has been cut in such a way that it reflects the most light. What most people don't know is that the shape of the round brilliant is the most uneconomical. As much as half of the original diamond is left out when it is turned into a round brilliant. For this reason, diamonds are sold in several other shapes as well, commonly known as fancy cuts.

Now some of the fancy cuts are already based on familiar designs, and will appeal to people even if they don't know much about diamonds. The heart and oval cuts are self-explanatory. The pear cut is often seen as an upside down teardrop.

On the other hand, how do you explain to people the differences between the Asscher and emerald cut, or the princess and radiant cut, when their shapes are the same? This is where we get a bit technical, but fortunately you don't have to get that esoteric.

Emerald and Asscher cuts are classified as step cuts. Compared to the round brilliant, they are rectangular in shape, with each side bordered with small steps. Step cuts emphasize lustre and clarity over brilliance. The Asscher cut has been popular for over 100 years, and its proportions are less even.

The princess and radiant cuts comprise a third category, known as mixed cuts. They evoke the brilliance of brilliant cuts, but are more practical to produce. The princess cut is the most popular next to the round brilliant, whereas the radiant cut has over 70 cuts.

When choosing loose diamonds, you need not be intimidated by technical knowledge. You can buy based on what cut you like. The jeweler, in turn, will narrow down your choices in terms of price and quality, and help find the best deal for you.

Access Your PC From The Road

Have you ever sat in front of your computer and wished you could show someone else what appeared on your screen?

Maybe you were experiencing a problem, or couldn't figure out how to make something work, but you knew if someone else could see what was happening on your screen, they could help you fix the problem immediately.

Ever had a phone conversation with someone about a particular business topic, but you just couldn't "connect" with your ideas because it was too hard to explain over the phone?

Now, visualize jumping on the phone with that same person and literally sharing your computer's desktop to collaborate, discuss, and create virtually anything together, even if you are separated by thousands of miles.

Though this may sound like an episode of Star Trek, remote computer sharing is actually a daily business reality.

Imagine you need to take a trip and you either don't want to or can't take your computer.

The thought of emails piling up for days makes you crazy and you also need to monitor some things on your pc.

Instead of trying to lug your laptop (or fit your desktop into your suitcase), you can use "remote desktop" software that allows you to access your computer through the Internet from any other computer in the world.

One of the most common remote desktop services is GoToMyPC.com, which provides a safe and secure way for you to go down to the local internet café, log on, and access your office or home computer just like sitting at your own desk.

Now, before you panic and think anyone can access your computer, let me explain security.

First, you log in to the GoToMyPC.com website with a username and password.

Once logged in, you then click a link to log onto your PC, which will then ask you for another password.

GoToMyPC.com has even thought of a solution for those of you worried about people looking over your shoulder as you enter your passwords on a public computer or if the computer you use might carry a keystroke logger.

Before leaving home, you can program in a series of up to 99 passwords that only work one time.

This means even if someone watches you log into your computer or records your keystrokes, the password you used won't work again.

If a would-be thief tries to access your computer too many times, GoToMyPC.com will shut down all access attempts to your PC.

The benefits of remotely accessing your PC from the road are numerous, but the bottom line is that it enables you to use your computer from the road like you never left home.

For example: while traveling to a conference this weekend, my wife (and business partner) accessed our office computer from my laptop and, instead of the usual pile of 4,000 emails that would normally await after 5 days away, we just picked up this morning like we'd never been gone.

The same company that offers GoToMyPC.com also offers a service called GoToMeeting.com which allows you to remotely host a meeting where multiple users can share and collaborate on a single computer desktop.

This service makes it super simple to provide online training, do software demos, and even make complete sales presentations.

I personally use both of these services and find them easy, reliable and well worth the price.

Different reasons for System Crash

The different reasons for your system crash are described as follows:

1. Hardware conflict:

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device. If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen.

2. Bad Ram:

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serioushardware problem. Sometimes it may mean a part is damaged and will need replacing.
But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force thecomputer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

3. BIOS settings: 

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and thecomputer becomes more unstable, you will know what settings to revert to.
A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze thecomputer’s display.

4. Hard disk drives:
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

5. Fatal OE exceptions and VXD errors:
Fatal OE exception errors and VXD errors are often caused by video card problems. These can often be resolved easily by reducing the resolution of the video display. If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse. The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

6. Viruses:
Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create aWindows start-up disk. A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.
