Accessory Computer

A home away from home is a great thing, so why not have an office away from the office too?The spare room or a quiet corner can be a perfect place for productivity. To outfit your workspace, you might need to invest in some new hardware like a second computer, a bigger monitor or a high-quality printer. Once you've got your home computer set-up, you'll need to connect it to the Internet or network it to other computers and peripherals in the house. With a good grasp of the facts and a firm idea of your work habits, you'll be ready to make sensible choices for your home-made office.

• The Computer. Not everyone needs the same level of performance in a home office computer. You might use your computer primarily for word processing and email which requires little processing power. On the other hand, you may want more power to run database analysis, large spreadsheets or graphics applications. The type of work you do and your work load will determine whether you need a computer with a lot of brawn or just a little.

• Processor. A computer's processor or central processing Unit (CPU) is the engine that powers the device. The speed of the processor is called the clock speed which measures how fast the processor can carry out instructions. Speed is measured in MegaHertz (MHz) and is one measure of a computer's power. A typical home office Windows PC should have at minimum a 500 MHz processor. A power user would probably prefer 800 MHz or higher. If you know your computing needs are modest, and you want to save some money, an older machine with a slower processor is worth considering. When looking at an Apple Macintosh, keep in mind that you can't simply compare processor speeds with Windows machines, as the two types of computers have different system designs. Macs generally have lower processor speeds in MHz but don't let that fool you. Newer Macs like the iMac can definitely keep pace with PCs.

• Random Access Memory (RAM). When the computer is turned on, RAM is used to hold the operating system, applications and data that you're currently running. Information in RAM is rapidly available to the processor. When RAM fills up, the computer slows down because it now has to retrieve information from the slower hard drive. Imagine documents on your desk in front of you, readily at hand when you need them. But when your desktop is full, you have to file and retrieve documents elsewhere, which takes more time. The amount of RAM you need is influenced by the type of applications you use. Graphics programs like Adobe PhotoShop or Illustrator use a fair bit of memory. Word processing and spreadsheet programs use somewhat less memory. Users who like to multi-task and prefer having multiple applications running simultaneously will definitely want plenty of memory. More memory gives you a larger "workspace" and makes your computer perform faster with fewer glitches. A typical user needs at least 64 MB of RAM with 128 MB becoming the norm. In virtually all computers, you can expand the memory as you need more.

• Hard Drive. This is the computer's filing cabinet where all your applications and data are permanently stored. Most users can fit many years of productivity into a 6 to 10 GB hard drive. If you need to store a lot of information like several years of business records or image catalogues, then you may want a more spacious hard drive. Luckily, a bigger hard drive won't cost you that much extra. Alternately, you could invest in a removable storage drive.

• Expansion. It never hurts to get a system with room to grow, especially if you foresee your home office needs evolving. Find out how many RAM slots a system has and what the maximum amount of RAM is. Adding expansion cards to your system for 3D graphics or ethernet will increase the functionality of your computer. Look for a system with two or three free expansion slots and room for additional disk drives.

Future Shock: Voice Recognition Identification Technology

VRIT, or Voice Recognition Identification Technology will soon become a pervasive part of our society. Are you ready for it? Please read a ficticious account how VRIT can be applied to work in the aviation industry.

Dateline: Tuesday, July 13, 2010

Location: Teterboro, New Jersey

The Schedule: N714JA, a Gulfstream V in Jet Aviation's Private Fleet, is scheduled to take off at 0830 for LAX. Crew of three with fourteen pax.

Backgrounder: Kay Hughes, flight attendant for today' s non-stop coast-to-coast flight is busy checking her catering order and prepping the cabin. Bob Harmon is the captain and Jeff Mortowski is his first officer. Both are situated in the cockpit going over the pre-flight checklist. The pax are from various companies in the New York area or individuals on personal business who have bought seats on his flight.

The Story: Kay woke up with a start as the alarm on her clock radio blared. Reaching across her pillow, she noticed the time, 5:15, and hammered the snooze button in the hopes of grabbing another five minutes of sleep. Tired as she was, her mind began to race as she considered the day ahead. In less than four hours she would be enroute to L.A. with an aircraft full of passengers. Slowly the thought of additional sleep became less important as she considered all that she had to do before leaving Teterboro. Quietly she slipped on her robe and slippers, poured herself a cup of coffee, and slinked into the shower.

As Kay walked across the tarmac, she saw the fuel truck pulling up to her aircraft and the caterer at the gate waiting for a security clearance. It was 6:48 and already she could feel the heat lifting off of the pavement. Another scorcher she thought; at least L.A. will be cooler.

Kay greeted Jeff who was busy overseeing the fuel delivery; she then climbed onboard the G-V and gave a similar greeting to Bob who was occupied with updating paperwork. Bob finished what he was doing and briefed Kay with the day's schedule. Minutes later Kay turned to assist the approaching caterer with the day's order. Within the hour, the first of the passengers began to arrive. Each sat in the lobby of the FBO waiting to be boarded. At precisely 8:00 a.m., Kay left the aircraft and walked down the ramp to the FBO. She whispered to the waiting security agent who signaled to the FBO customer service representative to make the boarding announcement. "Ladies and Gentlemen, Jet Aviation Flight #001 departing TEB for LAX is now boarding. Please present your identification card and boarding pass to the security agent. Once you are cleared, you will be boarded. Thank you for flying Jet Aviation and enjoy your flight."

Kay turned and left the FBO and walked back to the aircraft. Both pilots were onboard completing their preflight preparations. Kay stood at the bottom of the steps leading up to the aircraft waiting for the security agent to bring the passengers to the plane. She knew that with fourteen passengers the security clearance would take a bit longer than normal.

Kay considered waiting inside the cabin to keep cool, but knew that it was important that she greet the passengers at the base of the steps in case one of them needed assistance climbing up." It must already be 85 degrees out here," she thought as she watched the heat vapors rise off the pavement.

After what seemed like an inordinate delay — Kay's hair was slowly losing style in the heat — Bob poked his head out of the cockpit and said, "Sorry for the delay, but we caught another one." Startled, Kay stammered, "You mean one of the passengers failed security clearance?" Bob replied, "Not only that but he is on the FBI's wanted list of suspected terrorists. The remaining passengers checked out okay, but we'll be delayed until the agents finish interviewing them to see if they knew the guy." Despite the heat, Kay shivered as she thought of the potential chain of events a terrorist onboard the aircraft might unleash.

Her fears gradually subsided when Jeff reminded her that the VOICE RECOGNITION IDENTIFICATION TECHNOLOGY (VRIT) unit in the FBO was flawless in the nearly six months of use. Over that time, twenty-six people with a criminal element were pulled, most of whom had been charged previously with petty crimes [such as tax evasion] and were either on the run or would be in violation of their parole restrictions had they left the state. Today marked the first time that a suspected terrorist was caught and as the squad car sirens wailed, Kay knew that this day would be anything but normal.

The above account is fiction, but it pre-supposes a couple of things that could occur in the intervening years that would bring about similar results, i.e., additional and more widespread terrorist attacks being a primary consideration. In addition, a change in the way we do business, i.e., selling seats to individuals instead of selling the entire flight to a company or an individual would have to occur — no longer would you have a lead passenger who could identify all of the other passengers. VRIT is now within reach and will, more than likely, become the norm of the day. Essentially, it works this way: a person speaks into a device that immediately matches the voice pattern with one in the database. The database identifies the person and when a match is made, the person is cleared [unless the database turns up a warrant for their arrest].

Naturally, in order to get onboard a flight we would require passengers to be part of that database. This could occur if VRIT becomes as mandatory as holding a social security number or a driver's license. Foreign nationals would have to be keyed into the same system to make it work, so the potential for a worldwide Orwellian-type system would be great.

Recently, I had the opportunity to meet with Russ Cooper, a managing partner with COMPUTEK, a Wall Street company that has developed the latest generation of VRIT. He shared with me that both the FBI and CIA use an older generation of VRIT and his company is marketing the current one. Their customer base potential is impressive: government agencies, security firms, airports, airliners, automobile manufacturers, you name it. Wherever a positive i.d. on a person is needed, their technology might be utilized.

According to Russ, the technology is fail-safe. When I mentioned that a voice impersonator like a Richard Little type could sneak by, he claimed that VRIT would still know who he was even with the "Richard Nixon" voice. Apparently, voice patterns are distinguishable even when disguised.

We did not discuss "price" as he was not marketing his product directly to me. I can only imagine that the costs involved would be significant, but then I began to think that they could possibly be offset by lower insurance premiums if insurance companies see the benefit of “guaranteeing” passenger security.

So what role could the flight attendant play in utilizing VRIT?  Perhaps in lieu of a security agent [especially in out of the way places like Bozeman, Montana], a VRIT unit would be assigned to your aircraft — much like a cardiac defibrillator monitor — and you would greet each passenger as they boarded the aircraft. Before the aircraft could be cleared for takeoff, the passengers would speak into the handheld VRIT and be given a security clearance on the spot.

Let's return to our story and amend it with the security check being placed directly in the flight attendant's hands:

Kay walked down the G-V's steps carrying her mobile VRIT device and waited as the passengers exited the FBO and made their way to the aircraft. She announced, "Welcome onboard Jet Aviation flight #001 bound for Los Angeles. Please speak your name into the VRIT unit. Once you have been cleared, you may proceed up the steps. The first officer will take your boarding pass and you may be seated. If you need additional assistance, the captain will be glad to help you."

One by one the passengers filed by, stating their name and waiting for the green clearance light to flash. As they spoke, a signal was transferred to an orbiting satellite and then beamed to VRIT headquarters in Washington, DC. As the last of the passengers approached, Kay continued to greet each one and wait for clearance. Finally, when all passengers were cleared, she climbed the steps and had both pilots speak into the VRIT unit. At last, Kay placed the unit in the First Officer’s hands in order to have him run clearance on her. Kay cleared her throat, spoke her name, but after an extended pause, the VRIT beeped loudly and signaled red. The color in Kay's face drained away and she turned to flee. Within moments several arms reached forward to apprehend her as sirens wailed in the background.

All she could think about was running away...

Startled, Kay awoke from her dream as the snooze alarm blared away.

Avast Antivirus Home Edition

Prior to trying the Avast 4.6 Home Edition, I was very much a Norton user. I knew there were a lot of free antivirus software out there but I wanted to be on the safe side and use something tried and true. However, with the increase of spyware and virus attacks, my computer was not always spared and there were times I couldn’t figure out what was wrong with it. That’s when I thought that it was time to try something new – and free.

Installation is very easy. Just download ...
Prior to trying the Avast 4.6 Home Edition, I was very much a Norton user. I knew there were a lot of free antivirus software out there but I wanted to be on the safe side and use something tried and true. However, with the increase of spyware and virus attacks, my computer was not always spared and there were times I couldn’t figure out what was wrong with it. That’s when I thought that it was time to try something new – and free.

Installation is very easy. Just download the software from the Avast website, free of charge. The only catch – if you can consider it that – is that it is for personal, non-commercial use only. The installation process is mostly automatic. You can choose to register it after installation in order to access free updates for one year. If you do not choose to register it then you can use it for 60 days free. Since the registration is free as well, there is no reason not to do that.

The user interface is simple and easy to use. Some people might not find that it doesn’t suit their taste as it looks something like Winamp – it looks fun, not very serious. However, that doesn’t take away its functionality. It actually adds to the experience as you can change the skin if you want to.

It gives you the option to run 7 providers. You can choose which ones you want to run. I use the following shields: Instant Messaging, Internet Mail, Network Shield, P2P Shield, Standard Shield, and Web Shield. If you use Outlook then you can opt to use that provider as well. The above-mentioned shields pretty much cover everything you do on your computer, providing extensive protection. The Web Shield is by far the latest impressive addition to this release. It monitors all internet traffic including spyware. It is also compatible with most internet browsers. If you are worried about the effect on speed, your worries are unfounded.

A drawback of this software is that it takes too much time to load up when you first turn your computer on. It may take several minutes. In the meantime, it would be difficult for you to run applications.

I think that is a minor inconvenience you can put up with. For something that is free and works effectively, I wouldn’t mind waiting for a couple of minutes.
