Data Recovery/Datenrettung & Securing Data on Computers

Filed under: Tech Life @ 11:35 pm

Data recovery is the process by which the data is recovered from damaged or inaccessible storage media. Data recovery is done from storage media like CD’s, DVD’s, Floppies, Hard disks, Magnetic tapes etc. There are two reasons due to which the data becomes inaccessible. They are logical damage and physical damage to the storage media.

Physical damage to storage media can occur in many ways. Magnetic tapes can break, get crumpled or dirt may settle on the tapes. CD’s and DVD’s can have scratches or the metallic layer may get damaged. Magnetic heads in hard disks can crash or motors may fail. The floppy is notorious for failing frequently due to bending, overheating, cold, dust etc.

There are other reasons like fires, electrical surges etc that can cause data to become inaccessible or lost. There are many methods by which data can be recovered from magnetic media or optical media. The methods most commonly used are Magnetic Force Microscopy (MFM), Scanning Probe Microscopy (SPM), Magnetic Force Scanning Tunneling Microscopy (STM) etc.

In these methods a sharp magnetic tip is placed closed to the surface to be analyzed. It interacts with the stray magnetic field. An image of the data is generated and then repairs are carried out on logical damage and thus the data is recovered. Many companies carry out data recovery.

Logical damage is the damage to the file system. It is not physical but a software problem. It generally occurs due to power cuts, system crashes etc preventing file system structures from being written resulting in file system being left in an inconsistent state.

Logical damage is more common than physical damage. This may cause strange behavior like infinitely recurring file directories, loss of data, system crashes, hard disks reporting negative space etc. The end result is that the operating system cannot mount the file system.

Most operating systems come with repair facilities like, Linux has fcsk utility, Mac has disk utility and Windows has chkdisk facility. There are other specialized programs available which have better repair facilities than the operating systems.

There are also other systems called journaling file systems like NTFS, EFS (used in Windows XP), ext3 and xfs which can be reverted back to their earlier consistent state. These file systems reduce the amount of data loss.

Data back up is the best way to prevent loss of data. The simplest method is to keep data on drives on which the operating system is not loaded. The other method is to write data on magnetic tapes, CD’s or DVD’s or have online backup.

Backups are very important for databases. Data backup is of 3 types. Full backup means backing up all data. Incremental backup means backing up of only the files that have changed. Differential backup is a mixture of these two. There is another method called continuous data protection in which when data is written to a disk, it is also written to another computer in a network.

Rapid Fire Laser Bullet Firing Mechanism

Filed under: Tech Life @ 3:59 am

Is it possible to make a high-powered laser machine gun that uses no gun powered and fires the bullets in such rapid succession that there is no worry of barrel melt down or missing your target? Would such a laser finding, aiming and firing machine gun type rapid-fire system be a worthy invention to protect our nation’s most important assets?

I propose we build one to determine if the concept is doable and a viable way to design a better defensive weapon. The Rapid Fire Laser Bullet Firing Mechanism “RFLF” could solve many problems and be a much safer system. Even the bullets themselves would be safe to transport or store in a weapons cache.

How would this RFLF system work? Well, there would be Argon Gas or CO2 Foam in the bottom cup of each bullet. The bullets would have a fiber optic center surrounded by copper inside of the center, which would be fairly small and surrounded by a center punch hardened interior. The fiber optic main centerpiece would go through the center of all the bullets lined up in the chamber end to end. As one bullet fired the bullet underneath it would melt the tip and push the fiber back to wires on either side inside the bullet body to the argon foam cup, as it fired it would melt the tip of the next bullet firing it and so on. Once you let off the laser fire button or a robotic firing mechanism stopped firing, the system would stop at whatever bullet it was on. Each round would contain additional on-impact explosives if appropriate for the application. The top of the tip around the melted center of the tip would be made of sapphire from a lab:

http://worldthinktank.net/wttbbs/index.php?s=1ee4d8e60f88ab695b8908ed537e7bff&showtopic=155

This system is preferable due to the fact that there is not shell to discard or produce. As a space weapon there is not needed for storage of extra shells or weight to take into orbit and there is no space debris from the expended shells. Also since the bullets would glow, you have every bullet as a tracer round. Think on this.

Dish Network – Satellite – Common Myths & Misconceptions

Filed under: Tech Life @ 8:16 pm

As with all technology, there are always common myths and misconceptions that prevent many people from experiencing that, which would drastically improve their lives. This is true with Dish Network’s digital high definition satellite television services.

Many people think that even though there may be 4 different receivers in 4 different rooms, everyone has to watch the same programming. This is not true. Dish Network offers 4 free receivers, one each for 4 different rooms, to enable different viewing interests.

The weather – it consistently affects the quality of programming. As a general rule, this is false; however, if there is heavy and consistent storming, there may be brief interruptions of reception. This is rare and is considered less of a problem to satellite subscribers.

Satellite reception is available only for individual homes. This is another myth as reception if signaling is excellent in apartment complexes as long as the dish is installed facing a southern sky. Many people have them located on their balconies or outside walls. Always remember, though, if you don’t own the apartment or home, be sure to check with the landlord before installation.

High-speed Internet service is only available through cable companies. This is not true. Dish Network offers high-speed Internet service via satellite. Location is not a problem as signals are transmitted through space from Dish Network’s satellites. You will not experience down time from server problems because of weather or maintenance. Rumor has it that cable companies tell prospective subscribers that their pricing is cheaper than that of satellite programming. This is not true. Comparisons reveal that satellite prices are within the same range and sometimes lower than cable providers with much more value per dollar. The increased availability of diverse programming in selections and the quality of imaging and sound make the difference giving you more for less money. Click on Dish Network now for a complete listing of programming and pricing information. Cable providers would also have customers believe that customers must purchase all equipment to receive satellite services. Again, this is not true. Dish Network offers all equipment and installation free of charge, and even gifts new subscribers with a Dish Network Digital Video Recorder – further enhancing viewing pleasure. All free with no requirement for long-term commitments. The only item you are charged for is the programming you desire. A lot of people think that because of the advanced technology utilized in Dish Network’s digital high definition satellite services; there would naturally be expensive equipment repairs at some point in time. While the nature of the expense of equipment repairs may be true, be assured that when you subscribe with Dish Network for an 18-month plan, you receive Dish Home Protection Plan free (regularly $5.99 per month). This is more or less an equipment insurance provided by Dish Network to save subscribers money in repairs and replacements of equipment. It is hoped that this information will dispel any misunderstands you may have head and enable you to make a positive decision to switch from cable television services to Dish Network digital high definition satellite television services.

What You Must Do to Get a MCSE Certification

Filed under: Tech Life @ 10:26 am

Being an MCSE, or Microsoft Certified Systems Engineer, can bring in some good money and give you a greater range of jobs to be obtained. To obtain an MCSE certification, you need to be able to pass six core curriculum exams, an elected exam, and a design course exam. While most will go to university for an MCSE certification, they can be obtained through online courses and by studying online guides. Taking the exam and passing with at least an eighty five percent is needed to become a certified MCSE according to an MCSE who took the actual Microsoft courses.

MCSE study material ranges from books that can be ordered and sent to you to purchased and downloaded to your home computer. A thorough knowledge of Microsoft systems is key and you’ll need to be able to know the inner workings of a computer system before you can think about taking an MCSE certification course.

Certain internet web sites contain examples of past exams as a way to prepare yourself and study for the MCSE certification exam. Whether you take the course online, through the Microsoft internet site or go to an accredited university for it, make sure that you go over the MCSE study materials thoroughly and study as hard as you can for the exam.

There are a wide range of locations of MCSE training centers. Some of these centers even have high end retreats to train you on the finer points of being an MCSE. For those who can afford it, one training center offers a forty day retreat in the Himalayan Mountains for just fewer than three thousand dollars.

This forty day, intense training session covers every single requirement needed in order to take the final MCSE certification exam and start your new career. If you can’t afford to spend three thousand dollars on flying to the Himalayas, then a cheaper way to do it is to go through a rigorous online study schedule on your own. There are online advisers in case you need help or an explanation. Once you’ve completed the courses, you can earn up to one hundred dollars an hour.

Water – the Perfect Fuel

Filed under: Tech Life @ 11:22 am

As a freshman in high school, I failed chemistry class due to an extreme disinterest in the entire subject. I do recall a demonstration in which the teacher hooked a large one and a half volt battery to a glass and wire electrolyzer that transformed water into separated hydrogen and oxygen. I would later learn that commercial hydrogen and oxygen producers also used this method in an inefficient manner that requires more energy than the fuel produced can generate through combustion.

In the late eighties I would learn that a boy genius in California learned to make hydrogen from water efficiently with a twelve volt battery and standard auto electrical system, during the 1970s. Around 1990, my machinist neighbor built a hydrogen generator that did not work due to defects in the plans the boy genius had drawn up in prison when he was no longer a boy.

My neighbor was not interested in correcting the defect when it was discovered and I was only a bit disappointed. My father was a hobby style inventor and he gave me a good idea for a cheaper and much more effective 12 volt hydrogen generator. I never got around to building it and decided there was no point in separating the oxygen and the hydrogen after splitting the water.

Because the hydrogen and oxygen have opposite electrical charges, they readily recombine as a compound I call hydrox. The man who discovered this gas and fooled with it to make underwater welders and cutting torches, named the gas after himself, so hydrox is also known as Brown’s gas. Simply put, hydrox is an oxygenated fuel, which means it burns hotter and faster than a non oxygenated fuel. In WWII the Germans used hydrogen peroxide as a liquid rocket fuel. H2O2 is a super oxygenated fuel, highly caustic, corrosive and dangerous to work with. Hydrox, however, is no more corrosive than water. Flat plate electrodes one sixteenth inch apart, made of stainless steel will last a long time if clean water is used. Clean water can be had from relatively inexpensive filters which can be carried on a vehicle. Having a good filter can also help supply one with potable water when clean water no longer flows from the pipes at home.

Big Energy talks only about a hydrogen economy. Using expensive technology to manufacture a product that can be made inexpensively by anyone who wants it. The idea of water power is far too democratic to control. The rain falls both on the just and the unjust. If people put water in their fuel tanks and make enough fuel with a few watts of electricity that then makes kilowatts or megawatts of power in a combustion engine, who will buy hydrogen at fueling stations? Most Americans buy water cheaply compared to its value because of its relative abundance. In the U.S. it is usually cheaper to buy than to collect, store or drill for. Dry nations only need water pipelines from neighboring wet nations. Seaside countries can desalinate and filter sea water and pipe where needed. How can the corporate fascists gain control of water? Only by convincing everyone we need their new technology.

Water is to democratic energy access as the internet is to democratic discussion, information distribution and personal activism. This fact will be concealed for as long as possible and a few of us will be wise to the game. Without water we cannot live long. It exists in altered forms with special properties. When we know what there is to know about water, we will be wiser than any who have come before.

Engineers forge ahead building hydrogen fuel cells. These cells apparently generate electricity by recombining hydrogen and oxygen. This means that hydrox will not be suitable as fuel cell fuel. However, simple electrolysis costs little more to collect the two gasses separately and send them to the appropriate ports of the fuel cell. Thus, water can power these fuel cells as easily as combustion engines of many types, including jet and rocket engines. It is also likely from basic chemistry that steam is more easily electrolyzed than liquid water. Temperature rises speed chemical reactions. Steam is quite easy to create with combustion engines, which are the space heaters for the great outdoors.

I often wonder why greenhouse gasses are so readily blamed for global warming, while billions of super space heaters are seldom accused of much contribution. Fuel cells would be a fine solution to all this combustion heat. How many volcanoes would we need to equal the heat of transportation every day? Are we not burning up the planet one day at a time? Most especially for the sake of corporate profit. Why do we so willingly play the game of don’t blame me, I just do as I’m told?

When water is our fuel, the environment does not suffer crisis when a spill occurs on a highway, an ocean or a storage container ruptures. When water is our fuel, old ships can run aground, break up in a storm and not destroy hundreds of miles of coastline and wildlife environment. When water is our fuel, cars do not burst into flame during rear end collisions. The great betrayers of humanity have known what I am saying for more than a hundred years, and don’t want us to have water power. Is it not time for some changes? Shall we choke ourselves and our children for corporate profits? What is our reward?

Hydrogen and hydrox are both gaseous fast burn fuels, just as vaporized alcohol, gasoline and diesel; except even faster burning with much greater power potential, also producing the usual oxides of nitrogen, unless in fact such oxides mostly form in slow burn engines due to the long burn time. In this case we can expect greatly reduced oxides of nitrogen with water fuel, as well. When we make water fuel at home we can operate stoves and heaters and combustion or fuel cell electric generators and make electricity for a few pennies per kilowatt. Do you imagine the electric utilities will be happy they do not need to purchase more generating capacity? Will they want us to supply them at wholesale prices? Could developing countries adopt water power and internet connections to vault ahead to the 21st Century? Is clean, cheap power a huge threat to all the traditional power? Of course it is. That is why the science savior has not provided us with this miracle of the 19th Century. How does it feel to be one or two centuries behind existing technology? Is it not shameful and embarrassing? Humiliating?

The corporate scientists, engineers and energy experts will continue telling us it is impossible to make hydrogen as cheaply as some garage and basement scientists and engineers have been doing for decades. The sad thing is we will just say OK, we believe you. There is no such thing as conspiracy except in the minds of radicals.

Paternity Testing – Are You Raising Someone Else’s Child?

Filed under: Tech Life @ 6:52 pm

The dawn of the DNA test

Back in the 1700s, the best way to determine paternity was by a good hard look and the child, followed by a good hard look at the father. Enough coincidences and maybe a relationship could be proposed. A hundred years later, eye color was discovered to be a paternity identifier. This theory has had its flaws exposed because of recent DNA advances. We now know that eye color is determined by at least six alleles, or genetic markers. Paternity testing has become a lot easier and affordable over the past few years due to advances in DNA science. Although an estimated 200,000 DNA tests are conducted each year by states needing to sort child-support and welfare issues, few people are willing to conduct their own at-home paternity test. They don’t realize the simplicity and convenience of an at-home paternity test.

How does a home DNA test work?

Paternity testing requires a painless sample from both the child and possible father. Even without a sample from the mother, DNA paternity test results are up to 99.9999% accurate-that’s one-in-a-million odds your results are incorrect. Most companies provide a free home kit for you to provide the samples and require you to send the kit back to the laboratory with the accompanying fee.

Because many companies are aware of the discomfort of drawing blood from a child in order to get a sample, buccal (mouth) swabs are being accepted as an alternative. By gently massaging the inside of the child’s mouth, cheek cells are collected. These cells are then sent to the lab for testing. Labs analyze up to sixteen genetic markers of the child and match them against the markers of the alleged father. Because each of us receives half our genetic markers from each parent, the results of DNA paternity testing are still accurate without the DNA information of the mother. Most labs will have results in 10 days and charge about $290 for a basic paternity verification test.

What else can a DNA test do?

DNA kits can also be used to analyze siblingship, establish cousin or grandparent relationships, determine twin zygosity (i.e. whether twins are fraternal or identical), identify ancestral origin, verify Native American decent, assure parents they left the hospital with the right baby, and most important, provide legal evidence-be prepared to pay a bit more for legal tests. Legal tests can be used to settle adoption issues, settle child-support disputes, and provide information for immigration files.

How to choose a DNA laboratory

  • Accreditation is a vital part of choosing a laboratory. Accredited labs have an annual audit and inspection, undergo internal and external reviews, and have their equipment calibrated for accuracy. Look for an ISO and/or AABB certification. Accredited labs will have a good reputation and near 100% track record for court cases.
  • Look for hidden fees. Some companies will charge you for the kit and then charge you again for the results. Also, double check when you order your kit that you’re only buying the results you need.
  • Ask about privacy. Make sure that your identity and intentions are kept secure.
  • Enjoy piece of mind

    Be confident that the questions you have can be answered. DNA testing is safe and stress-free. Find a free kit and an information packet and you’re on your way to getting the piece of mind that you deserve.

    Are The TMobile Pocket PC Exchange And Repair Programs Worth The Effort?

    Filed under: Tech Life @ 4:43 pm

    TMobile Pocket PC exchange and repair programs are just one of the things that consumers like about this top notch carrier. Through this program, a customer may ask for repair services or an exchange of his handheld via TMobile Pocket PC Repair Centers or through the assistance of a T-Mobile Customer Service representative.

    And according to customer reviews, the T-Mobile Pocket PC repair and exchange service is something that consumers can indeed rely on.

    TMobile’s After Purchase Service

    As a T-Mobile customer, you can avail of the exchange or repair program if your Pocket PC is still within the warranty period (usually one year) and that the defect or damage is through no fault of your own. If such is the case, T-Mobile will send a replacement Pocket PC.

    Upon receipt of the Pocket PC replacement, you will then have to fill out a replacement form and send it with the defective Pocket PC within seven days. Otherwise, T-Mobile will charge you the amount of the handheld replacement.

    If, however, your Pocket PC is more than a year old (i.e., out of the T-Mobile warranty period), a replacement can still be dispatched to you while repairs are being done on your Pocket PC for a $70 fee.

    Don’t want to pay the $70 fee? Call a T-Mobile Customer Service representative to know more about other options you may have regarding your defective or malfunctioning Pocket PC. Don’t be shy; many Pocket PC consumers are unaware of the options they have when it comes to repairs, rebates and exchanges concerning their gadgets.

    A note about T-Mobile exchanges – if you have an old model handheld such as a Toshiba Pocket PC, T-Mobile may not be able to provide replacements or repairs for these handhelds because their manufacturers do not make them anymore.

    Is yawning contagious?

    Filed under: Tech Life @ 4:41 am

    It is a fact to any observer that yawning flies like a butterfly and stings like a bee. Scientists and others studying yawning, seem to have reached that same conclusion. Yawning is indeed contagious. But why?

    Yawning is thought to be a reflex act of opening one’s mouth wide and inhaling due to an increase of carbon dioxide in the bloodstream. By inhaling deeply – during yawning that is – a large amount of oxygen is breathed in and the accumulated carbon dioxide is expelled. Yawning usually occurs when one is bored or tired. During these periods of time, one’s breathing rate slows and this has as consequence to increase the carbon dioxide concentration in the bloodstream. An average yawn has duration of 6 seconds and this does have a significant effect to the heart rate, and thus the distribution and expelling of oxygen and carbon dioxide respectively. The heart rate in fact increases on average by 30% during yawning.

    However to answer the question of “why yawning is contagious,” three leading theories have been put forward namely the physiology theory, the boredom theory and the evolutionary theory.

    The physiology theory proposes that the infectious nature of yawning occurs as a result of an involuntary realisation that a deep intake and belching of oxygen and carbon dioxide respectively are needed. When Guy A sees Guy B yawn, it is a reminder to Guy A that he too may be feeling the lack of oxygen and this consequently makes Guy A to yawn as well.

    The second theory – and possibly the most entertaining one – states that yawning is simply a way of showing others or ourselves that something is mundane or boring. But in this theory, yawning is not really contagious. Instead other people yawn because they too find that same thing mundane or boring rather than depending on one person to spread the yawns. However if the interviewed people found something dull, chances are that the others found it equally tedious. Therefore everybody opens his mouth wide and inhales some oxygen.

    The third theory – which is the most appealing to me personally – is the evolutionary theory. According to this theory, yawning is a behaviour started by our ancestors, the cavemen. This theory puts forward that yawning was a sort of social signal to others. Therefore when one yawns, the others yawn back to return the call. This behaviour thus persists even today, according to the evolutionary theory, but it has faded away much. This explains why about 55% of people who see somebody else yawn will do too so as well within the following 5min.

    In humans, the earliest yawns occur before a baby is born, in the mother’s womb, only 11 weeks after conception. This clearly seems to show that yawning is a reflex action above all. Those 3 other theories are pure suppositions up till now and have not been proven by any scientific study even empirically.

    Also all 3 theories have major pitfalls. The most eye-catching one applies to the first theory, the physiology theory, which proposes that yawning occurs due to accumulation of carbon dioxide in the body and lack of oxygen. Studies have shown that receiving additional oxygen didn’t decrease yawning and people exposed to a lower amount of carbon dioxide didn’t stop yawning.

    For the boredom theory, well, I am pretty sure that out of those people who do not regularly visit art galleries, only a fraction will yawn and yawn on their first visit to expositions even if they find the stuff boring.

    The third theory seems to walk its way to the why of yawning, on playing cards. The evolutionary theory can easily crumble because we do not know whether cavemen were yawning first and foremost. As the theory builds itself on a very debatable fact, it may easily collapse.

    For now though, I’ll keep my mouth wide shut. But by the way, how many times did you yawn while reading this column?
