Should You Upgrade Your Hardware PC

by: Tony Gevano What if you found that your computer is out of date? You probably want to upgrade your computer since you have no choice to do so. Your works depend on your hardware computer upgrade. That’s how you going to have a good result.

But before you make any further step, try to learn about your computer. Search all options and ask for advice. Only after this you can go and buy a new component. It’s also useful to check if you really need an upgrade.

Sure, it’s not funny if you keep your old computer but you still loose data when you do your works. Its just a matter of time before you experience a hard drive problem when you still using your old computer. You dont want to loose your data, right? Of course most people only think of backing up their data after they experience a problem. Don’t set yourself up for a data loss disaster. Check what hardware you need for your computer.

If you have problem with your hard disk, such as crash when you do your work, better you have it renewed. Most people upgrade their hard disk to increase the size so that they can use it for games, movies and playing a lot of music. A 20 GB hard drive is sufficient to keep new office and internet applications, and all your files and data. A medium sized hard drive would be around 40 GB and the maximum would be around 60 - 80 GB.

You can choose which perfect for your work. Of course the price is also depending on the capacity of your hard disk. If you are a gamer, you may want to have high capacity hard disk such as that 60-80 GB. But if you just used it for your writing, a 20 GB is more than enough.

Another hardware you may need to upgrade is the RAM or Random Access Memory. This memory keeps data that is being worked on now and may or may not be transferred to the hard drive that represents the long-term memory of the computer. Current processors can perform an enormous number of operations per second. Almost all computer have 64 MB RAM and often 128 MB. If you want to run newer applications on your PC then you must upgrade to 128/256 MB RAM. A lot of people who upgrade from 98 to Win 2000 discover that their computers lock up very often. This is because they don’t have enough RAM.

Software For Your Kids

by: Zack Macchio Computers are all the rage today for people of all ages including children. There are many different types of software that you can choose from when it comes to picking something for your children to enjoy on the computer. Depending on the age bracket of your children you’ll have to take some time to choose software that does what you want it to do.

For the younger child aged three to five there is software that features some of their favorite television characters such as Dora the Explorer or Bob the Builder. Your children will be both entertained and educated as they play games, learn the alphabet, and learn to count. Software for very young children is easy for them to play so that you’re not always coming to their assistance whenever they press a wrong key.

Software for older children aged five to ten has even more interactive features than software for the younger child. You can buy software that is exclusively for learning and software that will only provide entertainment. Most software comes with a rating to let you know that it doesn’t contain any material that is inappropriate for children. Some types of software for this age group of children include puzzle games, software for learning a second language, math and science software, video game software, software for the artist, and software that allows your child to connect with the internet and play games with other children around the world.

Software for teens is something that you’ll need to supervise a little more closely since much of the software on the market can be objectionable and will often test the morals and virtues that you are trying to teach your children. When you buy software for your teen make sure that you take a good long look at what the software is all about, since many of the software games can feature a large amount of violence. There are, of course, software programs for your teen that are educational as well as fun and that they can use to enhance their schoolwork.

With so many different software choices out there how do you know that you’re making the right choices? Check out some of the parental listings that can be found on the internet. Many parent websites will offer you advice and ratings for much of the new software that comes out each month. This way you can be assured that other parents are approving a certain piece of software before you make your purchase.

Spyware Programs Are Out To Get You

by: Lawrence Andrews The average computer is packed with hidden software that can secretly spy on online habits.

The US net provider EarthLink said it uncovered an average of 28 spyware programs on each PC scanned during the first three months of the year.

There are currently over 38,000 spyware and adware programs that are infecting innocent Internet users such as yourself through downloadable games, music, screensavers, pictures, pop-ups, emails, and the list goes on and on. Spyware and Adware can cause your PC to run extremely slow and even crash, and allow hackers and advertising companies to invade your privacy whenever they wish.

What Is Spyware?

Spyware is a broad term for programs that collects information from your computer without your knowledge or consent. Spyware is a software program that transmits a unique code to identify you (for tracking purposes) without your knowledge or consent. The programs collects or transmits information about your computer use, or other habits without your knowledge or consent.

This internet pest which is better known as spyware installs itself on your computer without your knowledge or consent. It performs other unwholesome duties, and continue to reinstalling itself no matter how many times you remove it.

Spyware!

It has become so pervasive that lawmakers in the US are looking into ways to prevent or regulate it. The Spy Audit by EarthLink reflects the results of scans involving over one million computers between January and March. It uncovered more than 29.5 million examples of spyware.

Why should I be concerned about spyware or adware?

Passwords, credit card details and other personal information could end up in the wrong hands.

Your computer could get unwanted viruses, worms or even Trojan.

You would receive unwanted emails.

Your computer could be used by malicious operators to do damage not only your own computer, but to other computer users too.

How did I get spyware on my computer and how do I eliminate it?

It usually happens when you visit a web site, and are prompted to download something that is said to be “necessary” to view or use features of that web site. Also, you might want or download a program that has some nice features, but also installs program code that can send information out without your knowledge.

“By tracking and publicizing the growth of spyware, we can better educate consumers of its risks and encourage them to take steps to protect themselves and their families while online,” said Christine Stevenson of Webroot, which conducted the scans.

SVG and Flash as the same species

by: MAricon Williams We can name several technologies for displaying 2D interactive vector graphics on the web however, two names rises among other contenders. These are the Macromedia’s Shock Wave Flash (SWF) and the World Wide Web Consortium’s (W3C) Scalable Vector Graphics (SVG). Unlike Flash SVG is not for sale.

Adobe’s SVG browser plug-in has achieved barely around 10% penetration, compared to Macromedia’s 90% for the Flash plug-in. Flash has already established an outstanding standard nevertheless, this did not make SVG an inferior technology.

In the past Flash was considered a de-facto standard under control of one single vendor. For this reason, W3C proposed a recommendation to achieve standardized 2D interactive vector graphics on the web. This resulted to the birth of SVG. Its first version was Recommendation 1.0 which was introduced in 2001. The current version though is 1.1 which was released on January 2003.

Some people asserts that SVG is as powerful as Flash. Some say it is superior. But still there are others who think it’s the other way around. Which is which really?! To help you decide here are some vital facts:

Use Flash in the following instances:

1. You must use Flash if you want to make a Flash-like website. To replicate it using SVG is hard to do.

2. If you want to create complex animations or games you can use any of the two. However, you must be aware that SVG’s built-in SMIL animation engine is very processor exhaustive. Conversely, good results can be achieved using JavaScript animations.

3. If your users are not that computer literate like for example children for a children’s site or a site appealing to a broad audience, you must use Flash.

4. SVG supports sound. Nonetheless, if sound involves important intricate details, use Flash.

5. Use Flash if you prefer WYSIWYG to script.

SVG is advantageous in the following instances:

1. Use SVG if your task is fully scriptable. You can try DOM1 (part DOM2) interface and JavaScript. It means that you can build your empty SVG image using JavaScript.

2. SVG can effortlessly be created by ASP, PHP, Perl and extracted from a database. Be cautious though in setting mime-types on the server.

3. It is XML meaning it can be read by anything that can read XML. Flash can use XML but it has to be converted first.

4. You need not apply Flash’s action-script because SVG does not code per browser. It has a built-in ECMA-script engine.

5. SVG runs on IE/NS4+NS6/Mozilla and on PC/MAC/Linux.

6. SVG can be transformed through an XSLT style-sheet or parser. It also supports standard CSS1 style-sheets.

7. Texts used remains selectable and searchable. Graphic “objects” can be grouped, styled, transformed or composited and embedded text can be searched or indexed.

User Friendliness: Do Computers Have to be Clinical and Boring

by: Daniel Punch While sleeping through a lecture recently I roused for just long enough to catch the lecturer saying that “Error messages should not try to be funny or amusing, they should be clear and concise”. This got me thinking about the ever-elusive goal of user friendliness. The concept has changed much over the years with packages such as DOS going from being one of the easiest packages on the market, to now being complicated, convoluted, and ignored. I have begun to wonder why I am being taught that computers have to be boring to be user friendly.

The predictable nature of computers is quite dull. I study computers and work with them, so I’m used to experiencing a certain number of faults every now and then. I find these dull and depending on how close my current deadline is, downright infuriating. On the Internet side of things there is little quite as irritating as running into a 404 page when you’re trying to find something. However, the other day I ran into a site that displayed random 404 Haikus and instead of being upset at the fact that my time was being wasted, I ended up typing in bizarre addresses just so that I could read all of the little poems. You can find a few lists of 404 Haikus from a simple search in Google. Humorous website Homestarrunner.com has an entertaining page when you get the address wrong that screams “Four-oh-foured!” and displays a very entertaining message. They have another 404 page on their site that is a hilarious cartoon you can watch.

In terms of applications, games occasionally have amusing error messages such as the one in ‘Escape From Monkey Island’ with the title “Congratulations, you have found a bug!” and concludes with “…get back to work”. There’s naturally a bit more leniency and tendency towards entertaining secrets in games. Easter Eggs used to be a lot more common in software applications. These are hidden sections of code that the average user will never activate but which provide an amusing result when they do. For a large list go to http://www.eeggs.com and search for a specific type of software program that you use. There may be a few minutes of hidden entertainment to be found.

Some of the greatest Easter Eggs came from Microsoft’s software stable. Word 97 used to have a great little pinball game built in if you followed the correct steps, while Excel 97 had a fun little ‘flight simulator’ built in. Unfortunately employees are apparently no longer allowed to include these after some offensive messages were once included in a program.

Companies now require a very professional image and software costs quite a lot to develop, so we’re likely to see all the amusing quirks removed from software that’s released making it nothing but functional. I think that this is unfortunate. I agree that error messages need to be functional and let the user know what’s gone wrong but there’s no harm in taking the edge off the fact that they’ve possibly just lost a few hour’s work by adding a little humor into the picture. As long as common sense is adhered to I don’t really see why my grey pop up boxes all need to say exactly the same thing and be filled with data that’s largely useless to me. Thank you, I realize that the program has encountered an error. I assumed this when it stopped working. Why not give me a reason to actually read error messages instead of having to dismiss them as soon as they appear?

I think the idea of user friendliness has become too clinical and precise. We have rules and structures defining what is or isn’t helpful. We put fancy, bubbly skins on the dull and mundane and think that we’re making it all more interesting. Just occasionally I’d like my computer to pop up and say “Human Error. Please replace user and try again.”

Video Game Violence…What do you think about it

Daniel Punch Ever since video game designers were able to put red pixels on their imaginary characters that had recently deceased, there have been people crusading against their subversive ways. The outrage at video games seems to be cyclic, fading very briefly before exploding into the public eye once more with renewed frenzy. The controversy seems to have sparked up again in recent times, with numerous crimes being blamed on the corruptive influence of video games. There have also been various “controversies” surrounding recent video games and their content in the areas of both violence and sexuality.

The first game to receive widespread criticism and media attention was the martial art fighting game “Mortal Kombat”. This game included large spurts of blood emitted from attacks and also “Fatalities” that could be performed on stunned opponents after their defeat. These Fatalities were gruesome animation sequences showing the victorious player killing their defeated opponent in a vast variety of ways. Gamers revelled in this new experience and the controversy surrounding the violence caused mass hype that informed the less informed gamers that the game was out there. Consequently gamers played the new game just to find out what all the talk was about, thereby greatly increasing revenue.

One of the largest sparks of controversy has been the recent “Hot Coffee” modification for “Grand Theft Auto: San Andreas (GTA:SA)”. This involved unlocking a sexually oriented mini-game that had been removed from the game before release, although evidently not from the source code. The creators of the game, Rockstar Entertainment, obviously realised that this particular part of the game was not appropriate for the video gaming public and removed access to it. An enterprising fan of the game found out and modified the original code to give access to the content once again. Lawsuits were brought against Rockstar for including such content in their game, although the validity of the lawsuit has to be questioned. If the game is simply purchased and played as intended by the developers, this admittedly tasteless and inappropriate mini game would never be encountered. It is not until the user-made modification is downloaded and installed that the player is able to access the content.

Regardless of who’s to blame, “GTA: SA” was re-rated in America and banned from sale in Australia. Oddly enough the gratuitous and encouraged violence in the game went largely unnoticed in the wake of the “scandalous” sex scenes involving clothed, cartoonesque people.

When examined objectively almost all games contain a certain amount of violent content. The kid-friendly bright and colourful “Mario” games by Nintendo feature a character stomping on animated creature’s heads. In fact the majority of games, even children’s games, involve the protagonist crusading against an enemy horde of some sort and generally “disposing” of them in some manner, whether it be striking them with a weapon or body part (feet, hands, possibly a tail depending on the nature of the character). The only real stand out difference is that in a children’s game the ‘bad’ characters will generally bounce backwards in a cute manner and explode with a humorous puff sound (or simply disappear) whereas in a game oriented towards older mature players, the characters are more likely to be (somewhat) realistic, spraying a gusher of red upon their demise.

Whenever some young person somewhere commits a violent crime these days it seems to get blamed on a video game, from “Duke Nukem” and “Quake” being accused for the Columbine High massacre, to a more recent incident involving a group of minors attributing their violent actions to the “Mortal Kombat” video games. Without any solid evidence either way it’s hard to say whether or not video game violence actually has much of an influence on players. To really be sure you’d probably have to have a control group of isolated children that have never seen a violent movie or played a bloodthirsty video game. History does however show that brutal crimes were committed long before video games or even movies came into existence.

Children are quite easily influenced by something that they’re excited about and I’ve seen this happen a lot. Playing a wrestling video game with a group of eight year olds often leads to the eight year olds screaming raucously and trying to pin each other down on the ground. Pre-teens will often punch and kick their way out of a cinema in terrible combat stances after having viewed a martial arts movie. The current content rating system in place is not geared towards consumer restriction; it is largely aimed at simply informing the public about what they are going to experience. Legal restrictions are not actually put in place until the higher, more severe ratings like in x-rated films. Parents, guardians, and society in general need to start taking an interest in who is viewing certain types of content. Instead of complaining about the entertainment a child is enjoying, the parent could be there at the beginning looking at the rating that is printed clearly on the packaging of all entertainment. A simple “I don’t think that’s suitable, how about this game? It has a lizard!” distracts the child a surprising number of times. In my experience, children genuinely just want people to take an interest in what they’re interested in, not just murmuring indistinctly, “Yes dear, that’s nice.” as the child installs the newest violent game.

What about the children that are playing the games in the restricted ratings categories? The only way that they can even get the game into their possession is if a parent (or someone of legal age) purchases the game for the child, or if the store disregards the rating guidelines in place and sells it to them regardless. Either way the fact that a game’s content has fallen into a minor’s hands is not the fault of the game developer.

I’m not out to defend the integrity of artistic vision presented in video games as many other gamers are. Frankly there seems to me to be little artistic integrity in rendering blood that is ever more liquid in appearance. I do however enjoy playing some games that are quite violent in nature and in many cases the violent nature of the game increases my enjoyment. Video games are escapism, there’s (arguably) no point in playing a video game that simulates something you can just walk outside and do (and yet sports games somehow consistently sell in large numbers… curious…). Interestingly I have never yet felt the overwhelming desire to break down into a kung fu stance and commit murder. Perhaps more important than simply banning questionable content in video games would be studying why this content is so appealing to today’s

What are Rackmount Computers

by: Max Bellamy Rack mount computers are essentially computer servers. Computer servers are not the ones you play games on or send emails to your friends with.

Servers perform a small number of specialized operations, some as little as a single operation, but they have the ability to perform it millions of times over and over again, quickly and flawlessly. And when one server is no longer adequate to handle the volume of transactions that a business may require, other, bigger, more powerful servers are needed. When the new servers arrive, they are networked into the system and to save space, are mounted on racks.

When the business with the servers is a steel company, or an automobile manufacturer, industrial rack mount computers are the standard. Stored in rugged steel frames, stackable in standard 19-inch racks, industrial rack mount computers are used for database servers, web servers and networks. Furthermore they are also quite commonly used in laboratory and workshop environments.

Linux is a special operating system that is basically a version of Unix, which has become the foundation of the Internet. When ISP’s like AOL and others came into existence, the amount of servers they needed to accommodate millions of customers eager to surf the web was staggering. In order to make space for that amount of computers, a special rack mounted unit was created to hold the Linux servers. Dubbed the Linux Rack mount Computer system, it became the choice for all of the new Internet businesses all over the world. Soon after, manufacturers of the Linux Rack mount Computer racks where inundated with orders and quickly fell behind schedule.
