    High Definition DVDs The Future Of Movies

    High Definition DVDs The Future Of Movies

    Its said that HD radio has become a hot ticket item in the technology field but there is something coming soon that should take things up up a notch ” HD DVDS ” yes you will seeon be able to watch high definition movies on dvd from the comfort of your home.

    So what are High Definition DVDs? well there two HD dvd formats that are being worked on as we speak one is called HD DVD and the other is called Blu-ray both of them support High defination films.

    Something that is really incredible about these dvds is that the HD DVD will be a single layer capacity disk that will allow up to 15GB and then their will be a dual layer one that is 30GB. You might think that is pretty impressive but that isn’t anything. Toshiba is in the process of developing a triple layer disk that will allow 45GB of data and then their will be a 100GB one that is four layer.. very impressive.

    Basically high definition movies require more space and thats why companies are developing these high capacity disks to allow this to be possible.

    What are the benefits of this?

    Well this means DVD movies will have even more on them such as Directors comments, interactive features, out-takes and even a 2nd version of the dvd which will be in High Definition, I believe to fully benefit from this you would need a good tv and dvd player.

    November 2004 was the start of talks saying that HD DVD would take over from regular dvds. Mind you blu-ray movies will require a Blu-ray player You should see both the HD DVD and Blu-Ray provide plent of space for high-definition movies this coming year.

    SOLAR COOKER / COOKING

    SOLAR COOKER / COOKING

    SOLAR COOKER / COOKING

    • Solar cooking is the simplest, safest, most convenient way to cook food without consuming fuels or heating up the kitchen.
    • The first solar cooker we know of was invented by Horace de Saussure, a Swiss naturalist experimenting as early as 1767
    • Box Cookers – This type of cooker has been the advantage of slow, even cooking of large quantities of food. Variations include slanting the face toward the sun and the number of reflectors.
    • With box cookers, the food will cook more quickly if it is divided into several smaller pots instead of having it all in one large pot.
    • Solar cooking is not only fun but it’s a great educational tool. Solar Box Cookers, constructed using cardboard, newspaper, aluminum foil, and a piece of glass will typically cook at temperatures between 225 – 275 F.
    • Panel Cookers – In this design, various flat panels concentrate the sun’s rays onto a pot inside a plastic bag or under a glass bowl. The advantage of this design is that they can be built in an hour or so for next to nothing.
    • Panel Cookers require only one box, aluminum foil, a jar and an oven bag, and can be constructed in less than an hour.
    • Parabolic Cookers – These are usually concave disks that focus the light onto the bottom of a pot. The advantage is that foods cook about as fast as on a conventional stove. The disadvantage is that they are complicated to make, they must be focused often to follow the sun, and they can cause burns and eye injury if not used correctly.
    • A good first food to try is a small quantity of rice, since it is fairly easy to cook and looks very different cooked than it does raw. Chicken or fish is also very easy to cook.
    • There’s no need to rotate the oven to follow the sun, though it will improve cooking times
    • A solar cooker is like a hot box, in which we can cook our food without any cooking gas or kerosene, electricity, coal or wood.

    Choosing a Computer Backup Approach for Your Small Business

    Choosing a Computer Backup Approach for Your Small Business

    Backing up may be the most important technical task you perform for your business. No matter what your company does, you’re likely to have critical information that can’t easily be replaced: your customers, employees, suppliers, or business processes.

    The essence of a back up is to copy your important computer information to another location for safe keeping in case disaster strikes. It may be the most important technical task you perform for your business. It is very likely that you have critical information about your customers, employees, suppliers and business processes that can not be easily replaced. A sound backup policy is a crucial consideration in determining whether to run any computer systems in-house.

    Considerations

    • Backup Approach

      The backup approach is perhaps the most important aspect when evaluating backup solutions. The reason: The approach determines the restore time, cost, and the backup products and services available.

      • 1. Partial / Data Only Backup

        Only the key data directories/folders or files you specify are backed up.

        You will need to review all your software to determine how and where your important data is stored.

        • Backup Storage Space

          You only need to backup the specific data you need so the storage space may be significantly less than your hard drive capacity.

        • Restore Time

          If only a few files need to be restored, recovery will be quick. However, if a full restore is needed where operating system software and other applications need to be reinstalled and reconfigured, it could take days.

      • 2. Full / Disk Image Backup

        The entire contents of a hard drive are copied or cloned.

        You don’t need to review all your software to locate key data because everything will be backed up. Data corresponds directly to backup time so more data means increased backup time and storage needs.

        • Backup Storage Space

          Since the operating system, other software applications and data will be backed up, the backup will represent the entire contents of your disk drive.

        • Restore Time

          Full restores can be done very quickly since you will not have to reinstall or reconfigure any applications. Most software also allows for quick single file restores as well.

    • Data Failure Events

      Below are the two main types of failures you may encounter:

      • 1. File Failure–A file has been accidentally deleted or has become corrupted. In this case, it is ideal to have multiple backup versions of the files in case you need to find an older copy that has not been corrupted. The file will need to be restored or the application reinstalled.

      • 2. Disk Failure–The computer is out of commission due to a hardware or software problem, fire, flood or theft. Unless the hard disk drive can be fixed or installed on another computer, a full restore will be needed. The operating system, applications, configuration settings and data will need to be restored.

        Note: There is an approach called RAID, (redundant array of independent disks) that can help protect against drive failures. While RAID is not technically a backup, it can keep you going in the event of a disk failure.

    • Ideal Backup Qualities
      • Be simple to use and manage
      • Allow a restore in time to meet business needs
      • Be regularly transported offsite to protect against a site disaster
      • Be verifiable
      • Provide for multiple restore points

    Features

    • Encryption

      Backup files are encrypted to prevent unauthorized access.

    • Remote Access

      Access backed up files remotely via the Internet.

    Implementation Options

    1. In-House Backup Solution

    You or a hired technology service provider will evaluate, purchase, implement, and maintain the backup hardware and software within your business.

    2. Internet Backup Service

    The software and the infrastructure to perform backups are provided by an Internet-based company. While a few services do advertise disk image backups, the truth is that most Internet backup services perform selective or data-only backups.

    Deciding

    The best way to go about settling on a backup strategy is to evaluate how each computer is used in the business. It is best to create a document to keep track of all your computers and some of the vital information. To find how vital a computer is to your business and what a recovery may involve you need to know (1) how many people use it, (2) what programs are used and (3) whether the original software is still available so it can be reinstalled. In general, computers should fall into the following main categories:

    • Desktop/Laptop

      Partial or data-only backups are the most common. If an Internet connection is present, then an Internet backup will likely be cheaper and less of a hassle than an in-house solution.

    • Server

      Depending on the business importance, it may be appropriate to perform both disk image and data backups, if a faster restore time will be needed. Servers may also contain more applications that may be difficult to reinstall and reconfigure. In-house implementation is usually the better choice, because Internet backup services are currently more geared towards limited data. RAID is also commonly used on servers to eliminate the possibility of disk failure which reduces your overall risk significantly. An alternative option would be to use a hosted server that includes managed backups.

    Related Tips

    • Tip 1 – Temporary Options

      Any backup is better than no backup. Here are some simple ways to make a copy of files to protect your business data:

      Local options

      • Use a thumb drive—aka a Flash drive—with capacities into the Gigabytes now
      • Use CD’s, DVD’s, spare hard drives

      Internet options

      • Make the most of attachments: many Internet services like Yahoo include a briefcase where you can upload files

      • Email Attachments: You can always email yourself a file or even a zipped-up folder containing several files.

    • Tip 2 – Central Backup Location for Everyone

      If you are trying to back up several machines and driving yourself crazy trying to track down the files, consider letting the users do it for you. Designate a computer or server to be the backup source and give each person a directory. Then, tell each user to copy their files periodically to the server or risk losing data.

    • Tip 3 – Common Directories on Each Computer

      If you are trying to help back up several machines it can also help to impose some common standards by creating standard directories e.g. c:userword; c:userexcel so you will not have to guess where user files are located. You will also want to make sure that the preferences for applications are updated to save all types of files in the new directories.
