8 Things People Need To Know About Gaming

Video games are enjoyed by young and old. However the internet, magazines, and more are replete with untruths about gaming. The world is replete with things like “ gaming leads to violence; gaming ruins the eyesight; kids who get involved with video games become school drop outs or fall into bad company ,” and more.

As parents, teachers, and adults we need to separate truths from untruths and take decisions about video gaming based on research and proven facts. Here are a few points to consider:

1. Many are convinced that video and computer games spur violence in kids. The truth is that today
90 percent of the male population and 40 percent of the female population play video or computer games and according to federal crime statistics juvenile crime is quite low and not on the rise. Criminals are rarely created by gaming, more often than not it is a number of factors like broken homes, poverty, drug habits, and more.

2. A popular belief is that video gaming increases aggression among kids. Many studies are based on narrow field samples and does not represent a fair sampling. Media hype promotes the conclusion reached by studies that have poor methodology or analysis. Violence exists all around us in the news, in the movies, and more. The worst aggression is that exhibited by road rage. While violence in games exists it is not a primary factor that leads to aggressive behavior. Kids must be exposed to a holistic lifestyle and have good values ingrained in them at home and in school. Research has in no way established a direct link between gaming and violence although many involved in the school shootings were gamers.

3. Video and computer games are made for kids. While this may have been a fact a few years ago today gamers age from around 6-80+ years. Gaming is a passion with the young and old and advances in technology have created a following among adults too. Games are rated so that parents can make wise choices when purchasing games.

4. Games waste time and have no positive effects. This is an untruth and studies by child development and other experts have found that games heal, enhance eye-hand co-ordination, sharpen thinking power, teach kids to make quick decisions, and enhance creativity. Gaming according to several experts benefits children in many ways and even inculcates motivation and self confidence.

5. Video and computer games are exclusively for boys and men. While there is some truth in this, today the female sex is “shoulder to shoulder” with men in every field of endeavor. Statistics show that today more women play web based games than men and there are many women involved in designing and producing games.

6. Games teach kids to kill. While the military does use games to train soldiers there is no logical conclusion that every kid who plays video or computer games will become a soldier. Soldiers have a different profile and it is the military training that makes them soldiers not just gaming. In fact James Gee in his book “ What Video Games Have to Teach Us About Learning and Literacy” establishes the “learning potential” of games; games inculcate problem solving abilities in gamers and teaches gamers to be team players.

7. Games are a waste of time is a wide belief. In fact experts prove that games can be positive if handled properly. Kids or adults must limit their gaming activities and indulge in other hobbies too. Games according to research allow gamers to role play and take important nation building decisions. Gamers can experience first hand what the decisions result in, this according to researches makes them consider the consequence of their actions before they make one not just I games but in real life too.

8. Video games make loners. Video and computer games are not isolating. In fact most gamers play in teams with people living all over the world. The internet has opened up many doors and gamers today learn from others, interact with many who are not even from their own culture or age. Gaming has no barriers and has created an open world.

Gaming is healthy if done right.

Why Use a PDF Conversion Tool?

PDF (Portable Document Format) was introduced by Adobe a couple of years ago. It spread fast around the world, becoming one of the most popular file formats available. PDF files can be read with the free Adobe Acrobat Reader, but also with other specialized programs, no matter if you are on Windows, UNIX or another operating system.

PDF files became so popular because of their advantages over other file formats. I explained that they can be viewed on about any computer. Then, their file size is considerably smaller than a similar Word document. This is happening because on creation, images can be compressed, or converted to other format. A big problem for users is text fonts. If you write your Word documents using a fancy font, another person might not be able to view that document, because he doesn't have that particular font installed on his computer. With PDF files that problem is gone; fonts are embedded into the file, making it viewable for anyone.
Another powerful benefit of the PDF files is security. How many times you wanted to make sure your work is not modified, or even stolen. Now, it’s easy to protect your files with a password and 128 bits encryption.

Creating PDF files is quite easy. There are main 2 ways:
First one would be to make it from scratch. You start with a blank page, and add text and graphics the same way you do when you are working with Microsoft Word. At the end, create your bookmarks, choose security options and save the output PDF. Project can be saved and the work continued later if you have something else to add.
But, what happens if you already have your documents written in another text editor, like Microsoft Word. Using copy and paste to transfer your work into the PDF editor is an option, but it could lead to problems.

The best solution would be to use a PDF Conversion tool that will make a PDF file using your existing files as input. This is the second way to create PDF files, and maybe the easiest. The main advantage is that you don't have to change the way you work. The only modification is that at the end, you convert your files into PDF.

It might look difficult, but it's not. The majority of the PDF conversion tools use a PDF printer. This means that they convert to PDF by "printing" your files. Actually, this brings a lot of new options, because printing is available in wide range of applications. This means you can print to PDF from Word, Excel, PowerPoint, AutoCAD, and virtually any program that allows it.

I always prefer the second way.

How To Build A Flash Game – Flash Beginners Guide 101

Gaming is popular world wide and most people play games without knowing how a game is actually made. It takes inspiration, verve, technology, and more to create a game that captures the mind and heart of players all over the world.

The first step to making a game is to have a story. The story or plot is thought about and developed by game designers or players. Once the game is conceptualized, writers and artists work together on the storyboard and create sketches of the sequence with instructions for the technology team. The sketches are then scanned on to a computer and the next step is to breathe life into the story and characters.

Among the many ways to create a game a popular solution is Macromedia Flash MX. This allows the creation of rich, graphic and multimedia driven gaming. Flash has a player, authoring tool, and a file format. Flash allows game developers to use:
• Rich graphics.

• Create files that are user friendly and can be downloaded over the internet.

• Allows the import of graphic formats. This means designers can use Photoshop, Illustrator, Freehand, or Fireworks to develop the game as long as the graphics are vector.

• Flash lends itself to the creation of quality graphics that can be broadcast over the internet.

Flash can be used to create action, adventure, educational, first-person shooter, puzzle, sports, or role playing games.

The actual process of creating a game is complex but involves:

• Creating the characters. Sketches are fine tuned until they are perfect. These are then transformed into 3D characters. The figures are scanned into a computer and a digital skeleton is created. This is what defines the size, shape, and movements of any figure in a game.

• Next the programmers use Flash to bring movement and emotions into the figures of the game.

• Movement and characterization of the figures is followed by special effects and creation of the environment. Skies, clouds, wind, reflections, shadows, and more add mystery and atmosphere to the game. Flash allows developers to produce realistic and complex environments. It is the environment that gives life and motion to a game. The 3D effects are created using polygons along with texture mapping.

• This is followed by coding. Codes are instructions written by developers that lends intelligence to the game and drives a game forward. The more complex a code the more thrilling a game. Codes establish logic to a game and generate the excitement and uniqueness.

• Once the coding is done the testing begins. The testing helps the developer fine tune the game before it is marketed. This is when the game is rated by the Entertainment Software Rating Board. The rating indicates the appropriateness of the game for different age groups.

Flash is user friendly and therefore popular software with game developers. The World Wide Web offers Flash Tutorials for those interested in developing games. There are articles and tips and guidelines as well.

7 Must Know Ways To Prevent Spam

Spam is the bane of everyone’s existence. Unsolicited mail flooding mail boxes has caused many problems world wide. The widely accepted definition of spam is “Electronic communication that contains material of a commercial, solicitational, or illegal nature, directed as part of bulk distribution to any address.”

The first step towards fighting spam is to learn how spam works. A useful source is CAUCE or the Coalition Against Unsolicited Commercial Email and the SpamCon Foundation. Log on to the World Wide Web and read about ant-spam laws, government stand against spam, and coalitions that are working towards prevention of spamming. Be sure to take part in anti-spam community efforts by joining forums and groups. Spam can be prevented from entering your mail box by:

1. Determining the IP address of the sender and blocking it.

2. Use blacklist services like SBL (http://www.spamhaus.org/sbl) or the RBL (http://www.mailabuse.org/rbl) that maintain lists of IP addresses that are know originators of spammers. Blacklist services are efficient in blocking spam as they use the latest methods in preventing spam.

3. Use the spam guard services offered by email services like gmail and yahoo.

4. White list services where only mail from known addresses are approved by the recipient.

5. Use heuristic engines that look for keyword patterns that match know spam rules and block messages that contain known patterns. Well known heuristic engines include SpamAssassin that has a high detection rate.

6. Networked vigilance an open source initiative that involves continued maintenance of a data base and then the mail server asks a centralized VR node, Vipul’s razor for spam listings.

7. Using Bayesian filtering engines like SpamBayes , http://www.spambayes.org/. This has its uses as well as downside.

Spam can also be blocked by configuring anti-virus software to scan emails for viruses. Desist from leaving your email address over the internet and signing up for freebies and news letters. Use a separate email account for this purpose. Stay abreast of anti-spam efforts and adopt the latest possible anti-virus software and firewall systems. Never open mails from people unknown to you and immediately report spam mails to the mail host/provider. Try standalone spam filtering software like Qurb eTrust Anti-Spam, iHate Spam, Spam Bully.

Experts at PC World reported that almost 75 percent of email is spam mail and that in their study they found that SpamCatcher was one of the most affordable and simplest of anti-spam tools. Another notable product was InBoxer which works only with Out Look.

Fighting spam is a world wide war and efforts are being made by software manufacturers, search engines, lay persons, as well as others.
