  • Delete Files Older Than a Number of Days From DOS

    Delete Files Older Than a Number of Days From DOS

    With the operating systems available today, using the graphical user interface (GUI) of the operating system has become second-nature for me. It is very easy to copy, move, and delete files through the GUI interface than typing out the commands from a command line.

    With all the user interface options in an operating system, there are many times where it can be more efficient to use the command line. In one such case, I wanted to create a simple method of deleting files that were older than seven days from a specified directory. While I could have written an application to do this, I wanted to make it more simple by using a batch file. With an additional executable available with the Windows 2003 SDK, I can easily delete files older than a number of days from DOS.

  • The Most Useful Laptop Accessories

    The Most Useful Laptop Accessories

    Modern laptops are miraculous devices in their own right. With a laptop, you can have the world at the fingertips at any moment through the internet. You can create documents wherever and whenever you want, or read and e-book, or play games. The extreme convenience of mobility has changed our society forever.

    However, many people are unaware that laptops are capable of even more. There are many laptop accessories that improve a laptop’s performance, make it able to do more tasks, and increase its practical functionality. Here are a few of the most useful laptop accessories.

    WebCam

    Most of the uses of web cams are obvious. They allow a laptop user to provide a streaming video from their location or elsewhere. They can also be used to record videos or take pictures. Most commonly, they are used in video chat applications like Skype. A decent web cam can now be purchased at a very reasonable price, and is very easy to install. Many simply need to be plugged into a laptop USB port, and then they’re ready to go.

    Cooling Pads

    Some laptops generate a lot of heat, especially high performance ones that are processing a lot of tasks and information at once. This can be extremely uncomfortable if you use your laptop where it traditionally belongs—on top of your lap. Cooling pads are used to provide a barrier between the extreme heat radiating from a laptop and your flesh. They also cool the laptop itself, decreasing the odds of it overheating and getting damaged.

    Wireless Mouse

    Sometimes, using the touch pad on a laptop can be very inconvenient and impractical. For those of us used to the traditional computer mouse, there are now options available for laptops. Using a wireless mouse is usually very easy. Simply plug in the USB receiver and the mouse is ready to go. And since most of them now operate on laser motion trackers rather than a spinning ball, you can use them on almost any nonreflective surface.

    Carrying Cases

    Even the sturdiest laptops are usually pretty delicate. A well-padded carrying case can make the difference if a laptop is dropped, which happens most during simple transportation anyway. A good carrying case can definitely be a worthy investment.

    Adding accessories to your laptop can help you be more productive or provide more flexibility to help you get your work completed.

  • Functions and Resources of Memory Card Data Recovery Software

    Functions and Resources of Memory Card Data Recovery Software

    Without a dependable, preexisting data backup system, recovery from memory card failures, and the resultant data loss can be expensive and near to impossible. At times, even the best data recovery technicians encounter insurmountable complications. But do not despair. Sometimes the process of memory card data recovery can be as simple as rightly applying the correct memory card data recovery software.

    Data recovery solutions come in three formats: 1) Hire a data recovery specialist, 2) Purchase professional data recovery software, or 3) Download a free data recovery software package. This article addresses the second two methods of memory card data recovery.

    Concept of Data Recovery

    SD Memory Card

    Flash memory has a limited number of write cycles. Writing zeros to the location of a deleted file would senselessly reduce the life of the memory card. Thus when files are erased, the system merely modifies the file directory so that the file seems no longer to exist.

    In seeking to squeeze the most possible write cycles out of a flash card, the system applies equal usage to ever area of the card. Before deleted file space is reused, the remainder of the flash chip must be filled up.

    This overwrite process is very useful for flash memory card data recovery. In fact, this is a best-case scenario for file recovery. Unless the memory card is physically unreadable, the right software, correctly applied, can help you recover lost data.

    Most every data recovery software package addresses the same issues with similar methods. They go after the underlying data by ignoring the conventional Windows file system. They typically work out of RAM memory so as to avoid any risk of writing data to the target drive or flash memory card. Use them to:

    • Fix partition tables
    • Recover deleted partitions
    • Recover boot sectors
    • Fix FAT tables
    • Rebuild NTFS boot sectors
    • Undelete files
    • Copy deleted files to new sources
    • Repair MFT using MFT mirror
    • More.

    Memory Card Data Recovery Software

    I make the following software lists for reference rather than for detailed application processes. All are considered effective data recovery packages.

    Don’t Keep Your Visitors Waiting: Monitor Your Blog’s Performance

    I am always concerned with the performance of my blog to the point where I try to test the performance on at least a weekly basis. My quest to make my blog perform at its best led me to use CloudFlare to cache and send my static content.

    There could be any number of reasons why performance for a blog, or website, decreases and many times you may be able to find the problem and fix it. Other times, such as the decrease in performance on your host’s servers, are out of your control besides alerting your host. In this post I’ll explain the tests I perform to test out the performance of my blog so I can find where my blog performance can be tweaked.

  • Five Main Types of Rechargeable Batteries

    Five Main Types of Rechargeable Batteries

    At present, there are five main types of rechargeable batteries that are commonly available for use in place of disposable batteries in electronic equipment. Each has its advantages and disadvantages, but for most uses at least one type can be counted on to save money and preserve the environment when used to replace a typical single-use battery.

    1. Nickel-Cadmium (NiCad) Batteries

      Still synonymous with rechargeable batteries among older users who remember when these were the only rechargeable batteries available, NiCad batteries are rarely sold due to restrictions on poisonous cadmium that is used in their manufacture. However, NiCad batteries are still in use for low-drain applications, even if users are being forced to replace them once they no longer hold a charge.

    2. Nickel-Metal Hydride (NiMH) Batteries

      The earliest successors to NiCad batteries, these commonly used and relatively inexpensive batteries are also the batteries that power most hybrid and electric vehicles. They can be relied on for most applications, but older batteries which have problems with self-discharge should never be used in smoke detectors as they can suddenly run out of power and leave you unprotected.

    3. Nickel-Zinc (NiZn) Batteries

      One of the newest types of rechargeable batteries for consumers, NiZn batteries are recommended for high-drain applications such as flashlights and outdoor equipment. The AA size NiZN batteries produce 1.6 volts which is higher than the voltage of disposable batteries as well as of NiMH batteries, which allows for better performance in motorized and light emitting equipment.

    4. Lithium Ion (Li-ion) Batteries

      Li-ion batteries are sold as replacements for camera batteries, and they are also the most common batteries used in laptop computers. Because they are easy to manufacture in different shapes, they are becoming the standard for use in personal electronics, and a built-in battery protection circuit keeps the battery operating safely and prevents overcharge.

    5. Rechargeable Alkaline Batteries

      Less common than other types of batteries, rechargeable alkaline batteries are similar to single-use alkaline batteries but have a chemical composition that allow them to be recharged. They are best used in low-drain applications, but once charged they are known to hold their charge for longer than other types of rechargeable batteries. This makes them ideal to have available for backup or emergency use.

    In general, using rechargeable batteries of any of these types is highly recommended, but batteries should be periodically tested when not in active use to make sure that they have not discharged. In addition, when replacing NiCad batteries with more modern batteries, it is best to buy a new charger as well.
