Technology such as the Graphical Calculators covered in this article are rapidly changing our world in many ways and becoming more affordable for the average person. Its worth mentioning however that better technology is actually properly defined as simply a better way of doing something we already do with whatever process we have at hand. Rather than thinking of better technology in terms of computers, hi tech gadgets and such, for example anytime we find a way to get to work 5mins faster than before we have found a better technology to improve our lives in some respect.

Graphing calculators are an extremely useful tool for students, scientists, engineers and mathematicians. They are basically handheld computers, much more powerful than normal calculators and capable of performing complicated algebraic functions. With a larger graphical interface, they are best known for their ability to show graphical representations of mathematical equations, and hence their name.

The Japanese company Casio first introduced graphing calculators in 1985 when they released their fx-7000G. Casio still makes graphing calculators today, but the market is now dominated by Hewlett-Packard (HP) and Texas Instruments (TI). Casio has since focused their marketing on the grade school and junior high school applications of graphing calculators, where HP and TI now control the high school, college, and professional markets.

Since most graphing calculators are allowed on standardized tests such as the SAT, they are a valuable tool for students. Some of the more modern models have a QWERTY keyboard setup and have thus been declared to be ‘computers’ and not calculators. These models are not allowed for use on the SAT, and are therefore not very popular amongst students.

**Running Commentary** - Its interesting to note at this point that Graphical Calculators are going to range in price quite a bit and you really need to first identify your needs and wants and when you go shopping make sure you don’t overspend for features you want but don’t really need. As technology so quickly becomes obsolete 1. many of the features will become obsolete 2. later models will be cheaper if not superseded by a later model with newer features and 3. are you going to actually have time to read the whole manual and understand how all the features work ? (I know I never figure out all the features of any new gadget or gizmo I buy)

The two most popular non-QWERTY style models today are the TI-89 Titanium Edition, and the HP-49G+. They are both generally as powerful as the QWERTY models, such as the TI-92 and the Voyage 2000, but are much smaller and more convenient. Their prices are nearly the same in most stores and generally fall in the $140-160 USD range.

Personally, I am a long time user of TI model calculators and would recommend the TI-89 over the HP. The TI is capable of better resolution on its screen, and seems a little more user friendly. The TI is often thought to be marketed more for students and other non-professionals, and for their needs it is more than enough.

The HP does have an SD expansion card upgrade available that can allow users a virtually unlimited amount of memory, but I don’t see a need for more than the 2.7 MB the TI-89 Titanium comes with. When I was in college I was able to put all the programs and even games I wanted on my TI-89 with space left to spare. Plus, the HP has suffered from a series of manufacturing defects, which though they have since corrected, still has me a little uneasy about their products.

When buying a calculator, it’s a good idea to research what your needs are exactly. Maybe you’re going to need a lot of memory and the HP-49G+ is better for your needs. If you don’t plan on using it for tests and don’t care about size, you might want to consider a QWERTY layout. Is there a specific model your instructor recommends? Are there specific models you aren’t allowed to use?

Whatever your needs may be and whether you are a student or a professional, graphing calculators can be a valuable asset to help you better understand the complex world that is graphical mathematics.

To wrap up our article about Graphical Calculators I wish you luck in putting your new technology to use in your home/work life. In the last 20 years I have seen so many examples of new technology come and go I cant help feeling excited about what I’m going to see in the next 20 years. Although many people seem to feel a sense of foreboding about new things changing their lives in a negative way I must confess that I don’t have this fear at all (at the ripe old age of 40 anyway). I understand that new and changing technology is not only inevitable but in fact is opening up more opportunities for us all than ever before in our history and we should only feel threatened if we choose to cling to the past and somehow expect the rest of the world around us to do the same.

Have you ever imagined the day when you have spent 4 hours on an important report, only to discover that you have run out of battery and all your work is gone? Don’t you wish you have a back up battery somewhere?

When you think of any kind of back up battery for your computer you may think that there is no way to have one on your system. In reality there is a way that you are able to have a back up battery for you computer, yes even the one at home as well.

There are batteries back up devices that are going to work for all different kind of computers. You may even already have a battery back device on your computer if you own and use a laptop all the time. That is one good thing about using a laptop computer all the time. If you are not one of the many people that use a laptop all the time and still use a desktop computer to do all your work all the time then you are going to want to start to look at the different kinds of back up batteries that are out there for your system. Especially if you ever ran into a problem when you are working on a project and all of the sudden the power goes out and you lost all the work that you did and forgot to save.

With many of the battery back up devices that are out there you are going to be able to have a little bit of time to save your work on the computer and even do a proper shut down with it when the power goes out on you. Just think of all the hassle that you are not going to need to go through if you have a battery back up device on your computer.

You are not going to need to try to remember what all you have done so far for the day and even have to retype it all in again when the power does return. That would mean that you are not going to need to work late nights trying to make up all the work that you lost because you forgot to save it and the power went out before you got to print or save it in the middle of the work day.

Do yourself a favor; spend some money to get a backup battery. It’s better to be safe than sorry.

I remember back when the answering machine was a relatively new invention. My parents thought that it was the most amazing contraption that they had seen in years. Our answering machine was large and it had a large cassette tape in it that recorded incoming messages and another large cassette tape that played the outgoing messages. We had a lot of fun creating new and interesting greetings for callers on our answering machine.

Many of the answering machine greetings were annoying and some were very funny. We recorded songs, we took turns creating messages and we always kept things new. One of the more annoying answering machine greetings was the well-known, “Hello…Hello. I can’t hear you…Can you speak up? I still can’t hear you…Anyway, we’re not home. Leave a message on the answering machine after the beep.” Many callers were extremely irritated with the message and often hung up on the answering machine.

Today, you can find new ways to annoy and amuse your callers through your answering machine, especially on your cell phone. There is a site called The Answering Machine that offers message downloads for your cell phone. You can choose from three hundred different greetings. The Answering Machine also offers many other treats for your cell phone as well.

The Answering Machine has a list of the top ring tones for your cell phone. One list provides the classic downloads for your cell phone answering system like the theme from the Exorcist and Mission Impossible and from popular music like Hey Jude and You Spin Me Round. Whatever your taste, you can find a great ring tone for your cell phone through The Answering Machine.

The site also provides a choice of co lour logos for your cell phone. The pictures range from cartoons to photographs to artwork. If you prefer a little movement, The Answering Machine offers animated logos for your cell phone. Many of these logos are downright funny and some are just plain scary. Many of the animated logos are appropriate for cell phone users of all ages but some are adult.

I am going to spend a little time looking around The Answering Machine’s website to find a great logo, some animated pictures and maybe a cool new ring tone. But what I’m really looking forward to finding is a great message for my cell phone. Over the years, I have run low on new and creative ideas. I figure that I can put my creative efforts elsewhere and rely on The Answering Machine website for free downloads that are guaranteed to amuse.

You’ve probably heard about progressive scan DVD players, but you may not know what exactly they are or why they seem to be the hot item that people want these days. To understand why this is the case, first you need to learn about the different technology that progressive scan DVD players provide. And then you’ll need to realize that at the moment, only those who have invested in HDTV or other high performance display screens or projectors will be able to take advantage of the difference.

To start with, let’s review the way that traditional motion pictures are created. In fact, the term ‘motion picture’ is rather misleading because no pictures actually move. Instead, still pictures, also called frames, are played in rapid succession so that the resulting display is changing so quickly and in such small amounts at a time that we perceive it as moving. You may have recreated this illusion in school or on your own by drawing stick figures or other pictures on a stack of paper, then flipped through the paper quickly. The figures looked like they were moving rather jerkily. But if you took the time to draw enough frames and move them quickly enough, you would see much smoother motion, like in cartoons.

Television is recorded in the same type of frames. Then it’s broken down to be transmitted in a signal. When the signal is received by your television, it is reassembled in sections, or stripes. These stripes are reassembled in two different sets, from top to bottom and left to right across your television screen. To explain this concept more clearly, imagine window blinds that are partly open. The actual blind pieces are one set of stripes and the space between the stripes represents the second half of stripes. In a TV transmission, the stripes of set one are laid in before the second set is laid in. This is called an interlaced display. Although it sounds like it would take some time, all of this happens in the fraction of a second – 60 of the fields or stripes are displayed per second.

DVD players and DVDs have used this same technology because of the fact that TVs displayed pictures this way. But with the advent of digital and high definition television projectors, display technology has changed, leading the way for DVD technology to change as well. These high performance TVs and projector screens receive and display signals in full progressive frames instead of stripes. And 60 full frames are displayed per second. Meaning even more detail can be included in the same amount of time, resulting in pictures with less flicker or picture distortions. Progressive scan DVD players work by sending DVD signals in the same progressive format.

However, progressive scan DVD players only make a difference if they have both the source material that can be scanned into progressive signals and the display screen that can receive progressive signals. Older DVDs were most likely not recorded with progressive signals. Newer ones will have the capability, though. But as mentioned before, you have to have a television that can receive progressive signals. HDTV televisions can, and so can CRT or LCD monitors.

If you have the right kind of television, a progressive scan DVD player, and a DVD that was produced in the last 5 years or so, you can test to see if you can tell an improvement. Just switch the DVD playing setup from progressive to normal as you watch the film. Look at the outline of things, and the details of the background elements. You may just experience home video with a clarity and sharpness like never before.

For most people cheat codes have a negative stigma; if you need to use the codes then there is something wrong with your ability to play a simple game. Although the losers can claim that they own the game and that they can do whatever they want with it. However, there are some appropriate uses for the cheat codes, even though those uses may be so wrong.

There are four basic kinds of cheat codes: devices, controllers, glitches, and Easter eggs. Devices are always considered cheat codes, as you bought the thing so you could cheat, so there is no question that you were going to cheat. Easter eggs (hidden codes) are at the other extreme; if you find one you’re actually supposed to exploit it at least once. Glitches are the ultimate gamer gray area; as glitches are random, exploiting is up to the person. Of course, if it happens a lot, then taking advantage of it is a bad thing. Controller cheats (using the controller to input a code) are not supposed to be used except in emergencies or for fun, and are otherwise bad mojo.

There is the obvious advantage of being able to finish games that have small…quirks. For example, if you accidentally sell off an item that is vital to solving a puzzle that you need to solve in order to continue the game, then it is nice to be able to put the item into your inventory in order to solve the problem. This solution also applies if you forget to buy an important item, find out that item is important and you can’t go back, and just about any other equipment issue. In other games, the ability to continue forward can depend on some bit of randomness, and you have problems moving forward. A cheat code can help you there, too.

Cheat codes can also allow you to explore the game in ways you couldn’t otherwise. For example, areas where the monsters are too tough or you can’t normally reach, using cheat codes are okay; at that point you’re just having fun, not doing anything serious. They can also be used to show off in front of friends, showing them things that make sense in no other situation. There is just a certain level of fun in showing your friends what a wrestler looks like in tutu, or being invulnerable as a normally weak character that has no business being in that part of the game.

Cheat codes may be something you should avoid using, but they can also be something that can lead to further fun, especially if you show your friends the codes. There can be a certain amusement in fighting off tanks with a high-powered slingshot. Although Playstation cheat codes were placed there for the designers to play with certain parameters, such as to see how things would change if those parameters would change, they can lead to a certain degree of scandal if it’s found out that you’re playing. Especially if no one’s there to see the fun!
