The current structure of most keyboards is neither intuitive nor mechanically necessary. The layout of most keyboards today is a remnant of the days of typewriters. The first typewriters had letters arranged alphabetically, but because hitting adjacent keys often jammed the machines, manufacturers rearranged the keys in order to distance letters that frequently occurred consecutively in language. The result was what today we know as the QWERTY keyboard, named after the first six letters on the top row.

We are so used to typing on the straight rows of QWERTY’s keys that an alternative way of typing probably seems impossible. But in reality, if you take a moment to look at your hands the next time you type on your keyboard, you’ll notice that your wrists are bent outwards. Most people never realize the awkward movement involved in typing on a keyboard. Human hand form favors typing at a slight angle. In fact, take a minute to look at how your wrists. Notice their awkward typing angle.

Learning to touch type can help increase your typing speed, reduce neck-related injuries, since you do not need to look down at the keyboard all the time, and increase your typing accuracy. Still, even touch-typing places unnecessary strain on your wrists. If you’re at a job where you spend all day typing, consider switching to an ergonomic keyboard, that is, a keyboard whose keys are structured to reduce the risk of Repetitive Strain Injuries associated with typing and to allow your wrists to remain in an more ergonomically sound position as you type.

Think of ergonomic keyboards as a means of supporting your body. We spend plenty of money on providing tech support for out machines, so why not get some for our wrists?

Ergonomic keyboards can range in price from affordable to very expensive, but that doesn’t mean you can’t get a good deal. Many online websites offer discounts on ergonomic keyboards. Amazon, for example, is offering the Microsoft Natural Ergonomic Keyboard 4000 for under $30.00.

Most ergonomic keyboards provide added support for hands, wrists, and forearms by splitting the keys down the middle and positioning them at an outward angle to allow you to type more naturally. Some also elevate the keys in an inward curve.

Switching to an ergonomic keyboard might take some getting used to, though. After all, just like switching between playing the piano and the electric organ or between typing on an Apple keyboard and a standard keyboard, your fingers need some time to adjust to the heaviness of the keys, the different spacing, and the angle. Once the adjustment period is over, you will find that your wrists and hands are much happier typing at an angle.

Ergonomic keyboards work normally with any computer device that requires a standard keyboard and require no additional computer support. So take advantage of online sales, and get yours today.

Recently we recommended looking for an Energy Star compliant computer monitor when replacing your current monitor.  Now, we would like to highlight one of the best Energy Star compliant computer monitors.  The ACER H233H 23” Monitor is all the monitor you will need and it can save you money on electric bills when compared to older monitors as well as many of its contemporary 23” peers.

The ACER H233H 23” Monitor measures 21.7” by 16.1” with a depth of 6.8”, so it has a sizable, but narrow, footprint on your desk.  Fortunately, the wide, thin desktop monitor has a little heft to it; at 10.8 pounds, it remains stable on the desktop.  The ACER H233H 23” Monitor has a stylish black frame that looks very modern.

The ACER H233H is a widescreen 23” monitor that supports 16.7 million colors with a maximum resolution of 1920 x 1080.  At that resolution for that color depth, colors stay vibrant and distinct and the extremes – black and white – feature increased contrast for the optimal video experience.  Best of all, the ACER H233H 23” Monitor connects to HDMI and DVI-D sources as well as traditional VGA computer outputs.  With so many options, the ACER H233H 23” Monitor may replace your television as your monitor for your Playstation 3 or other HD gaming console.

The ACER H233H 23” Monitor includes all of the cables needed to connect the monitor to a PC, which is a rarity in today’s market.  The connectors included include the audio hook-up so the ACER H233H 23” Monitor may project your computer’s audio right from the built-in speakers.  The speakers on the ACER H233H 23” Monitor are 1.5 Watt stereo speakers which deliver a powerful wave of sound if you are sitting an average distance away.  The ACER H233H 23” Monitor may discourage you from leaning close with its booming sound system.

Power consumption is exceptionally important these days, especially with electricity prices constantly going up.  The ACER H233H 23” Monitor is Energy Star compliant and when in use, it draws an average of 38.6 Watts.  The 38.6 Watt rating is dramatically less than the 55 Watts the Asus VH236H, which is also a 23” widescreen monitor.

At an average online price of $220, the ACER H233H 23” Monitor is an affordable Energy Star compliant monitor that is made with the legendary ACER durability.  Especially for those replacing an older monitor, those who have not seen just how chic and powerful the new flat screen, widescreen monitors can be, the ACER H233H Monitor delivers more than the average user will need.

When you are in the market for a new computer monitor, you should consider one that is Energy Star compliant.

The Energy Star rating is a certification defined by the United States Environmental Protection Agency and the Department Of Energy, not computer support services, computer repair shops or computer manufacturers.  As it becomes more chic to be environment-conscious, computer manufacturers are chasing the Energy Star rating, just as consumers look for the rating when purchasing a new monitor.

What does the Energy Star rating on computer displays actually mean, though?  At this point, most computer monitors are plug-and-play, so there is no additional computer support required to install or run an Energy Star compliant monitor.  In order to get the Energy Star certification, a display must only use one Watt while off and two Watts while in a sleep mode.  The power consumption guide for Energy Star certification varies with the size of the monitor display, but in order to get the certification, a monitor must use about 20% less power than the non-compliant monitors.

What many consumers are unaware of when they purchase an Energy Star compliant monitor is that some require the computer to be set to make use of the energy-saving benefits of the display.  You may avoid a call for computer support simply by checking that the display’s Energy Star benefits are activated.  With a properly configured monitor, the display will conform to Energy Star qualifications with no need for ongoing computer support or maintenance.

The need for computer repair or monitor repair is much less likely when consumers purchase and properly use an Energy Star certified monitor.  By running the display with the Energy Star configuration active, the monitor runs cooler and last longer, especially when the monitor is turned off.

In addition to lowering computer repair bills and avoiding computer support calls for monitor-related problems, using an Energy Star compliant monitor properly lowers the electric bill.  Consumers who use multiple computers with Energy Star compliant monitors will likely see a noticeable drop in electric bills, as 20% off one of the larger power draws adds up!

Shopping for monitors with the Energy Star certification benefits the environment, saves you money on monitor power usage, prevents embarrassing computer support calls and costly computer repair bills, making it a smart investment for all computer users.

Software companies are beginning to market some of the best video slot machine games from casinos for home use.  While online video slot games can lead to grave concerns over Internet security, home computer software for video slot machine players offers the thrill of video slot machines without the threats, hassles or gambling debts.  The coolest video slot machine game on the market is IGT’s Lucky Larry’s Lobstermania.

Lucky Larry’s Lobstermania is a collection of 20 IGT video slot machine games released for PC and Mac by Masquepublishing Software.  Lucky Larry’s Lobstermania includes Cats, Stinkin’ Rich, Betti The Yetti, Carnival Of Mystery, Da Vinci’s Diamonds and other games that are instantly recognizable to anyone who has been to a modern casino.  There are also more obscure games like Price Check and Frog Princess that may not have been part of IGT’s staple line-up.

The interface for Lucky Larry’s Lobstermania is instantly cool.  Before going to any machines, you enter the virtual casino where you can see banks of the video slot machines.  It is a cute gimmick and it is enough to get anyone who likes video slot machines into the mood to play.  Masquepublishing also includes ambient noise from the virtual casino to make the experience more vivid (that may be turned off without losing the sound effects from the game you want to play if that is not your thing).  When you pick out the game you want to play, you click on the video slot machine and your screen becomes the cabinet for the game.

Like most of Masquepublishing’s IGT video slot machine games, Lucky Larry’s Lobstermania allows you to take your virtual winnings with you from machine to machine.  As a result, you may feel like you are winning more and more in your virtual casino.  The software may be set for ideal odds which allows you to build up your bank fast and experience bonus games more frequently.  With ideal odds, you win more often.  The software may alternatively be set for the casino odds, which could be a great object lesson for young children enchanted by the idea of gambling that you want to disenchant!

What is extraordinary about Lucky Larry’s Lobstermania is that it includes games that have bonus games much more sophisticated than the standard IGT releases.  Instead of just free spins, games like Betty The Yetti include bonus games that tell a story and build upon themselves.  On Betti The Yetti’s bonus game, players watch their multipliers and “adventure bonus” increase as Betty walks around her park!  Lucky Larry’s Lobstermania also includes Da Vinci’s Diamonds, a cascading reel video slot machine that is an exciting mechanic not available on any of the other IGT games released so far.

Lucky Larry’s Lobstermania installs easily from CD-ROM without the need for any additional computer support.  Gambling can be costly, stinky (all that smoke!), and involve travel: Masquepublishing and IGT make it fun and risk-free with Lucky Larry’s Lobstermania!

As the worldwide economic instability continues and nations look to protect jobs for their own citizens, Americans who buy with the motto “Buy Made In The U.S.A. Only” are facing an impossible task when it comes to computers.  While there are thousands of United States-based businesses for computer support and computer repair, finding a computer with all of the components made in the U.S.A. is virtually impossible.  Long before the technology sector began to outsource computer support and computer repair jobs, U.S. computer companies exported jobs in computer manufacturing to countries with more lax environmental, safety and worker’s rights standards.

Unfortunately for “Made In The U.S.A.” purists, the Christmas 2011 season has no computer offerings that are entirely the result of United States manufacturing.  For sure, there are a number of computer support and computer repair organizations in the United States, like Rescuecom, touting  a workforce as 100% U.S. Based.  However, even the computer support companies that assemble new computers make their computers using components made outside of the United States.  It is a similar thing for computer repair companies; it is possible to get a real, live American to answer your call, but if hardware is required to fix your computer, there is no way to guarantee every part will be from a U.S. manufacturer.

Is computer support from the United States the most consumers should expect?  Realistically, yes.  While phone-based computer support may solve many problems, physical computer repair is sometimes necessary.  Physical computer repair for hardware issues will always be less expensive the more local it is; the odds of outsourcing computer repair jobs to other counties and forcing users to mail their systems to another country is ridiculously low.  But computer support positions seem to be one of the last bastions of quality American service whereby consumers may contact a highly-trained, highly-educated and comparatively local professional to receive aid.

What would it cost to make a computer entirely manufactured with parts made in the U.S.A.?  There is no hard data on that, largely because U.S. businesses do not synthesize most of the components needed to manufacture a computer and they have not for years.  But with the lingering computer manufacturing jobs in the United States having an average hourly wage of $21.03 (in 2008), conservative estimates would put the manufacture of an all-U.S. computer over the $1000 range for even the most basic models.

While consumers seem willing to protect their investment through customer support services and computer repair companies that require serious financial commitments, the American consumer seems unwilling to spend as much on the initial expense of a computer.  Who can blame consumers for not wanting to spend more on computers created with a model of planned obsolescence?  The best consumers can do is understand that the global economy is now very interconnected and that the best investment in America might well be supporting U.S.-based computer support and computer repair companies like Rescuecom.

It has been almost eight years since bovine spongiform encephalopathy, more commonly known as Mad Cow Disease, was an international story.  While dramatic agricultural reforms in the meat industry played a large role in keeping Mad Cow Disease from spreading, computer support via computerized models continue to play a key role in monitoring and preventing a Mad Cow outbreak.  Computer models that calculate far more accurately than a single person could are now protecting humans.

According to “Mad Cow And Computer Models: The U.S. Response To BSE,” the sheer number of variables needed to calculate the vectors of a Mad Cow Disease outbreak are staggering.  Despite the seemingly daunting task of correlating all of the necessary data through computer support techniques, the USDA now has a model to predict and calculate the vectors of a Mad Cow Disease outbreak.

One of the significant challenges in predicting and tracing the outbreak of a prion disease like Mad Cow Disease is that the disease is only evident through an autopsy of an infected cow.  Once an infected cow is found, the race begins to trace back all of the relevant factors in that cow’s life.  Those factors include: the food source that each infected cow was fed from, every location where the cow lived, every cow in the herd with the infected cow each time the infected cow was sold and the location of the infected cow’s parents and offspring, if any exist.

To get this data, the USDA must have access to complicated databases of shipping records, sales records and inventory controls for both cattle and the cattle’s food supply.  While the USDA must be vigilant for these models to work, the most common challenge to the model is human error, missing data, or computer support failures.  However, with the database working ideally, the USDA hopes to have a rapid response plan in place to prevent both an outbreak that would endanger the United States and a series of sweeping mass cattle executions that would effectively end the beef industry.

The USDA’s database, if properly maintained, will allow ranchers to target specific cattle when authorities find an infected cow.  Based on feed source, herd and sales records, the USDA would inform every rancher who had a potentially exposed cow in their herds.  In other words, the database provides the possibility that the infected cow’s food source could be traced back and then predicted for all cows in the database.  Then, ranchers would be notified of which of their cows were likely infected with Mad Cow Disease and they could be killed before ever entering the human food chain.  And, if potentially infected cows already entered the human consumption market, the USDA could issue a more precise recall.

The computer models for Mad Cow Disease rely upon vigilance, precision and updates over a long period of time, but they offer the greatest potential for humans to survive an outbreak.

When one spends thousands of dollars on a dog, they need something that protects that investment and the Garmin Astro Dog Tracking System does exactly that.  A family pet can be one of the most expensive investments, from the initial purchase to the ongoing investment in the dog’s health and training, and it is the investment most likely to literally run away.  The Garmin Astro Dog Tracking System may not be able to prevent escape artist dogs, but it does allow one to find a dog on the loose.

The Garmin Astro Dog Tracking System is a GPS system for medium to large dogs that comes with both the Astro 320 handheld device and the DC 40 collar unit for on the dog.  The Astro 320 handheld GPS device is self-contained and, as such, does not require any additional computer support to operate or update the unit.  The DC 40 collar is a specialized GPS transmitter that interfaces with the owner’s Astro 320.

The Garmin Astro Dog Tracking System is like a standard automobile GPS system.  The DC 40 is a collar that one simply puts on their dog and activates.  With a seventeen to forty-eight hour charge, the DC 40 ensures that a lost dog will not stay that way for very long.

The Astro 320 component of the Garmin Astro Dog Tracking System is a handheld GPS device that includes a bright, full color screen with preloaded topographical maps.  The position of the dog is indicated with a high-contrast color dot or, when tracking a moving dog, a line.  The Astro 320 also features a compass module to help the user more effectively follow the escaped or hunting canine.  With the tracker function on, the Astro Dog Tracking System easily keeps the user informed to prevent users from following a dog’s trail after the dog has doubled back or changed direction.

One of the most appealing features of the Garmin Astro Dog Tracking System is that the system may be used the moment it is removed from the box.  The user does not need to subscribe to an expensive monthly mobile phone plan to access the data from the transmitter.  Unlike many pet GPS products, the Garmin Astro Dog Tracking System does not rely upon any other product or service.  At the same time, the Astro 320 features a port through which the user may upgrade to premium services, but most users will find the out-of-the-box benefits of the Garmin Astro Dog Tracking System to be more than enough to safeguard their dog’s wellbeing.

Hunters, tourists, dog owners on vacation with their beloved canine and owners whose dogs who have a large property to roam will find that the Garmin Astro Dog Tracking System is all they need to recover their dog when the dog escapes.

In the wake of news stories about viruses and identity theft, Internet security remains a very real concern for everyone who goes online today.  Internet security issues have created a big business for programmers in the virus removal industry. But with dozens of computer anti-virus programs available on the market, it is hard to know which provides the best virus removal and the greatest Internet security.  For that, the best response may be overkill.

Researching Internet security issues and virus removal protocols is enough to make the head spin of anyone who is not a trained computer expert.  Astute computer users who just want to check out what the current threats to their computer are become baffled by technical jargon.  Looking at reports from the major Internet security companies like Symantec are likely to leave the average computer user confused.  After reading their report on the Packed.Generic.340, most computer users will not know how serious a threat it represents to their computer or if they need any form of virus removal.

Many companies that specialize in Internet security rely upon more than one antiviral software product to ensure they are adequately protecting their computer or network.  Some of the leading Internet security companies take the time to test the leading products on criteria like malware detection and virus removal.  AV Comparatives recently released their report on their tests of anti-viral software.  Even that, though, may be too much for the common computer user to handle and process.  Their testing methods are rigorous, methodical and designed for the best minds in Internet security and virus removal to understand.

Businesses only survive online when they have adequate Internet security and powerful virus removal.  Thousands of businesses and home computer users use the Rescuecom Internet Security Suite.  Rescuecom has one of the most reputable Internet security and virus removal products on the market.  As a leader in Internet security and virus removal, Rescuecom has a proven track record for business and home computer users.  Even though the Rescuecom Internet Security Suite may have more virus removal options and greater Internet security provisions than the average user is likely to need, you have to ask, “If the professionals are using this much protection, shouldn’t I?”

The answer, of course, is that you should.  With the threats of identity theft, infections that require aggressive virus removal and emerging Internet security concerns, private computer users should not skimp on their anti-viral software: overkill is safer than being under protected.

For several months, the Occupy Wall Street Movement has been going on in New York City.  The protest, currently physically clogging up New York City’s Zuccotti Park, seeks to bring attention to how the 1% of the wealthiest people control the fates of the remaining 99% of the population.  There is a strange disconnect in the literature provided by Occupy Wall Street through their website and the physical protest; it is unclear how the protesters hope to bring change to economic inequality through randomly clogging up a park near the Wall Street financial buildings.

What is fascinating is how every sector of the media is trying to make a statement about Occupy Wall Street.  On November 15, the Wall Street Journal posted a video online in which three reporter/commentators discussed a spike in Twitter activity the night before.  Twitter has been an invaluable tool used by members of Occupy Wall Street to communicate with one another through their smartphones.  The story focused on how Twitter traffic quintupled from about 100,000 tweets with Occupy Wall Street hash tags to 500,000.  This occurred when police came into the park in the middle of the night to clean.

The attention social networking media gets through stories like this is enough to make legitimate journalists and private citizens blanch.  A quick Google search of November 15 and Occupy Wall Street leads readers to surprisingly little information.  Legitimate news sites note that an eviction happened and that authorities allowed protesters back into the park by morning.  In a protest that has had moments when the major news outlets have covered police violence and significant crowd actions, a spike in Twitter traffic pertaining to Occupy Wall Street seems like a non-story.

The Wall Street Journal tacitly admits as much in the podcast when Zachary Seward notes that much of the traffic that contributed to the Twitter spike did not come from people actually in Zuccotti Park.  This is a textbook definition of hearsay and is more an illustration of how fast small events can be blown out of proportion.  When the Wall Street Journal treated what was essentially a high-tech game of “Telephone” as a legitimate news story, Edward R. Murrow rolled over in his grave.

Twitter could be a great asset to the media or to Occupy Wall Street, but the way people who are not involved in stories use Twitter to relay messages as if they were present sets a dangerous standard that journalists today, at the very least at the Wall Street Journal, seem content to follow.  The non-story from the Wall Street Journal calls to mind a brilliant parody done by The Onion News Network about assumed casualties from a train wreck.  At least viewers for The Onion know to expect humor as opposed to serious stories; we expect better from The Wall Street Journal.
