How to Get Your Best Buy in Desktop Computers

Many of you are die-hard Mac lovers and many of you are PC fanatics. For the PC-ers, this is for you. Most PC consumers are under the impression that a desktop computer becomes obsolete after one to two years, but this is far from the truth.

The computer I currently work on (and play high quality games with) is about five years old and will continue to perform for another two. I’ve never had to bring it in to a chain store’s tech squad, either. So how did I buy a winning computer?

Before the basics: a computer budget

Computers are usually over-priced in the chain stores, but even if you get one built, expect to pay about $1200. This may seem like a lot, but think of the benefit in the long run. A decent computer will almost never need to be repaired and you won’t need to trade it in after a couple years. This is five to seven years of no stress!

The basics: computer terminology

The most basic thing you need to be familiar with is computer terminology. It’s important you don’t wholly rely on the sales associates to help you make a final decision. A sales associate’s goal is to sell, not inform. They tend to use terminology able to make a lemon computer sound like lemonade. When customers don’t understand the terminology, they can end up making poor decisions. Here are some hardware and Microsoft Windows terms to be familiar with:

Hardware

  • processor (also called CPU): this is the “brain” of your computer
  • RAM (also called memory): used to perform tasks, such as keeping programs running
  • hard drive: storage space for all files and software
  • video card: the piece of hardware to create what you see on the screen

Another term to always remember: the box that holds all the above hardware is called a computer, not the CPU. I realize before the days of hard drives, the big box was called a CPU, but it’s more than this today. Your CPU is now about the size of a postage stamp, but the large box part holds all of the above. While this fine point in terminology won’t help you pick out a computer, using correct terms will make one appear less vulnerable to sales associates.

Microsoft Windows

  • OS (operating system): the program a computer needs in order to run. The two Microsoft operating systems most commonly available are “Windows XP” and “Windows Vista”

The OS is the program that controls your hardware and runs all your software. Windows XP is the older OS, but it’s far more reliable and requires less out of your computer. It works with newer and older technology. Vista is the newest OS, but it has many glitches and requires updated (and more expensive) hardware.

Computer specs: what to look for

Once the computer terms are clear, they can be used to determine the usefulness of a computer. Below is a basic guide on hardware, but certainly isn’t the end-all manual.

RAM

  • Recommended RAM amount for Windows XP is 1 Gigabyte
  • Recommended RAM amount for Windows Vista is 2 Gigabytes

Technically, Windows XP can run off of as low as 128 Megabytes and Vista can be run off of 1 Gigabyte (or 512 Megabytes for Vista Home Basic), but so much performance is sacrificed that the computer becomes unusable.
I personally recommend at least 2 Gigabytes of RAM across the board. With 2 Gigabytes, XP can be upgraded to Vista and Vista will then have enough RAM.

Processors

  • Good Intel processors: Pentium, Core 2 Duo
  • Failed Intel processors: Celeron (and anything not Pentium or Core 2 Duo)
  • Good AMD processors: anything Athlon
  • Bad AMD processors: Sempron, Duron

Processors are difficult to understand, because AMD and Intel use a set of names and numbers to show the quality of each processor. Unfortunately, the numbers only compare within a brand. This means one can’t compare the numbers of an Intel to an AMD — it’s an apples to oranges comparison. The numbers are a sort of code to tell computer builders the specs of the processor and while this is helpful for gamers, the casual computer purchaser doesn’t need to worry about the processor specs. You’ll be fine, so long as you follow the above chart.

Currently, the Core 2 Duo is generally the stronger processor, though it’s the most expensive chip on the market. AMD has a chip like Intel’s Core 2 Duo (called the Athlon X2), which is cheaper than Intel’s chip and performs slightly worse. I recommend the Intel Core 2 Duo, because your computer won’t become outdated quickly. If your budget is too tight for the previous chips, I recommend an Athlon 64, but be warned: it is already outdated.

Video Cards

  • ATI
  • Nvidia
  • Never buy an Intel video card (in my opinion)! Most people don’t care about their video card, because they think the video card doesn’t impact the usability of the machine. The video card is actually another integral part of your machine. It controls everything you see on the monitor.

A poor video card may cause:

  • movies to become choppy
  • menus and programs to display slowly
  • the monitor to display lines or other strange visual occurrences
  • problems with scrolling a web page

So how does one avoid this? The best advice I have is to never purchase a machine with an Intel video card. I encourage you to spend the extra money on a better and faster card — anything on ATI’s or Nvidia’s product line should suffice.

Wrap up

The best thing to remember is to not make an impulsive purchase. Bring a pen and paper to write down all the computer specs, then research. It would be horrible to confuse Athlon and Celeron processors when you’re shopping — the Athlon gives top performance and the Celeron is a poor processor! A computer is an investment, so take the time to make your investment last.

Savvy Safety: Self-defense

It seems as though increasingly more women are victimized and while one can’t know all the details on each attack, a simple fact becomes apparently clear: this trend needs to stop. We can’t control the attackers, but we can control our reactions. By changing our habits and gaining practical knowledge, we can keep ourselves safe.

Dissecting criminal activity
The best defense from being attacked is to stay away from dangerous situations. Investigator Tim David of a Police Department in Wisconsin outlines criminals’ attention to victims: “They [criminals] behave much like animals in their predation.”

Noting this fact, predators then seek the following behavior in prey:

  • Disoriented
  • Out of place
  • Not confident
  • A person looking down, shoulders slumped
  • Frazzled or scattered
  • Incapacitated or helpless (hands occupied with bags, for example)

For years, we believed attacks only happen in dark alleys or in empty parking lots, but this isn’t true. In fact, a woman was recently abducted in a crowded parking lot in daylight. It doesn’t matter the time of day or location [for an attack to occur]. If a predator knows you’re alone — even in your house — they will attack.

Preventing an attack
So, what’s a girl to do? Investigator David advises for a woman to save herself by being “aware of her surroundings.” Meaning, you should be in the habit of scanning the parking lot when you both exit your car and a building. Be wary of anything or anyone who seems out of place. In addition to knowing your surroundings, scan your car. Check the backseat and under the car, looking for someone trying to hide. David commented on a case when a woman went to unlock her car door, a man was hiding under her car and lunged at her knees, knocking her over.

Other safety tips include parking close to the entrance, staying in lit areas and keeping within a crowd. Also, if both your hands will be occupied (with shopping bags, for example), use a cart. If attacked, it is much easier to let go of a cart than it is to drop armfuls of bags. David adds as a final precaution, “Trust your instincts. If you feel in danger, your subconscious is giving you danger signals.” He notes that our “woman’s intuition” is a powerful safety mechanism not to be ignored.

Reacting to an attack
Even with all the prevention and smarts we have, we still don’t get a 100 percent guarantee on thwarting an attack. The ability to kick a guy in the shins is no substitute for locking your doors, but if some fool attacks in a seemingly safe environment, girls, with a couple of steps, can fight back and have a chance for escape!

Just like the criminal behavior used in scouting potential victims, we can also predict how a predator will attack. He will first stare at his target. For example, if he’s staring at your neck, he’s about to lunge for your throat.

He’s not aiming to kill you (yet), he will instead perform a “blitz attack.” He’ll suddenly close in, using his size and strength to overwhelm you. His ultimate goal is to throw a woman “off kilter.” He may start punching repeatedly or forcefully grab from behind. If he’s coming from the front, it may be enough for him to close the space.

Our defense against this behavior begins in our minds. “Fights are won first in the mind, before a fight breaks out,” investigator David notes. You need to consider the idea of being attacked anywhere; then mentally role-play your reaction. An attacker’s blitz won’t stun so much if you’re expecting it; the stun effect comes solely from surprising you. Here are some moves for effective role-playing. Remember these moves can be mixed around — use your own discretion in which to employ.

Role-play #1: Rushing from the front
First, if he can use a stun technique, why can’t you? You don’t have his size, but you can use a verbal stun. Since the attacker is so focused on his target, screaming will stun him in much the same way he planned on stunning you: It’s an overload of the auditory sensory nerves; he expects you to act like a victim, but you’ve just changed the dynamic. A momentary stun gives you just enough time to prepare an attack and run.

Now you have a number of options. If you felt unsafe in the present territory, you may have stuck your keys between your fingers. Use those like a cat uses its claws and scratch across the attacker’s face. Your own fingernails could be used much the same way: tense your fingers into a sort of claw and swipe at soft tissue.

You also have the option of using weapons at hand. Do you have a pen in your pocket? Jam it into his throat. The same effect can be reached using two tensed fingers, but you’ll need accuracy: feel along your breastbone. Feel those ridges right up by your neck? Now, right in the center of your neck, above where the breastbone meets your throat is a soft, hollow spot. If you felt it, it probably made your breath catch. Imagine if someone pushed there — it would incapacitate an attacker long enough for you to run away.

Your hands are your most powerful weapon. Punching a guy in the nose will make his eyes water (which means you can run away without being seen). You can also perform an ear stun: cup your hands, like you’re about to fill them with water. Remembering that this is an attack, swing your hands up in one swift motion around the attacker’s ears, cupping the ears in your hands. When performed correctly, you can cause temporary deafness, due to the unusual amount of pressure created in the ear canal. Plus, it’s painful.

Notice: all these attacks end with you running away. We may be strong women, but we can’t take men on face-to-face. You want him incapacitated so you can run and call for help. I’ve been studying martial arts for years, and this best defense is still to beat it.

Role-play #2: He gets his hand on you
And this hand needs to go. Use your common sense on this one: odds are good he’ll loosen up his grip if he were kicked in the genitalia, shins or knees. Many stuns or small attacks will cause him to loosen his grip. If one doesn’t work, try many others.

Try this handy stun to loosen an attacker’s grip: make a fist and look at the back of it. Notice the tendons. Now, take your other hand, make a fist and rap your knuckles against the spots between the tendons on your first hand. Hurts, huh? I can feel a shock up my forearm and my fingers jolt apart slightly. When paired with another bigger attack (like a swift kick to the groin), this stun is very effective.

Role-play #3: His arms are around you
You are now in one of the worst situations — your movement is limited and he has complete control. You can try to kick a shin or stomp on a foot. I suggest a move I call the “toddler defense.” Have you ever seen children who didn’t want to leave the park? After some crying, they sometimes go limp (like a rag doll) and become impossible to hold. An attacker won’t expect something so strange (especially in an adult) and his grip will loosen. Be sure to follow up immediately with another stun or attack.

Role-play #4: On the ground
The ground is the worst place to be — all that’s left is defense. Fortunately, you may have a way out. You have the option of curling up into a ball: pull your arms and knees into yourself as close as you can. If you’re on your back, you can also fix your knees to make a triangle (the floor makes the base of the triangle). Women’s hip muscles are especially strong, making it impossible for anyone to pull your legs apart.

Post-attack pointers
Although being attacked may be the most traumatizing event you’ll encounter, you’ll need to remain lucid enough to be a good witness. Try to remember anything distinguishing: license plate number, tattoos, scars, birthmarks, weight, height. Write down everything you remember as soon as possible.

Investigator David gives an important warning: “There’s a period of time after trauma where you’re impressionable. If you talk to anyone before the police, you may have a false memory imprinted.” Also, the authorities do realize you may feel sensitive about sharing personal information, so don’t be afraid to ask for a female officer. Remember: you have no reason to be ashamed of anything that has happened!

After speaking with the police, you’ll need to get biological evidence collected. So, as hard as it might be, don’t shower or wash your hands (his DNA may be on you), don’t eat or drink (in case they need blood work), don’t use the bathroom, don’t change clothes … Evidence can be anywhere and the littlest thing could lead police to find the attacker.

Just remember to stay safe. Don’t take unnecessary risks, use these tips and some common sense, and you’ll be better prepared if something should happen.
