Game Development - Story Bible Example

Posted by admin On October - 23 - 2008

The bible deals exclusively with story and its elements. While the design document guides the creation of the entire gaming experience, the bible controls the game’s interactive screenplay.

Log Line

Let’s say we’re working on a game titled “Hangnail,” the latest game inspired by Quake. Hangnail’s bible would include a “treatment” or synopsis of the game’s story. That treatment should include one- or two-sentence reviews of the story’s beginning, middle, and end. In some cases, the treatment could go into greater detail, stretching from one page to 20 or more, if the designer or game writer chose to really flesh out the story in the design stage. If the game’s narrative is truly based on cinematic story construction, the story might include first, second, and third act reviews. Leave those bits to your writer—we waste hours worrying about that act-structure nonsense. At the very least, the synopsis should include a “log line,” or a brief review of the game’s story, like this:

Hangnail:

Synopsis: A big, tough guy with heaps of muscles and a heart of gold walks through mazes and kills lots of stuff to battle evil, find his boxed lunch, and save the future of humanity…at least until the sequel comes out.

Characters

The second portion of the bible would include character reviews. The most important component of any effective narrative, whether it’s in a game, a movie, a TV show, or a novel, is good characters. They should have well-rounded histories and solid motivations. Most importantly, they should be clearly drawn out so anyone who reads the bible or works on the game sees the same person in their minds. If a writer or designer creates a game revolving around a Schwarzenegger-type action hero and fail to describe his all-American, psychopathic personality, the artist or renderer could end up drawing Marv Albert. Here’s what our character bible would say about Hangnail’s protagonist:

Character Name: Dirk Squarejaw

Age: Late 20s

Appearance: Ruggedly handsome and in the kind of impossibly good shape that you’d need to spend 25 hours a day in a gym to achieve.

Equipment: Death Ray of Death, Grenade of Severe Owies, Swiss Army Knife of Animosity, Pulse Cannon of Mild Mood Swings.

Attributes: Wonderfully and relentlessly violent. With an overdeveloped sense of honor. Dedicated to saving all life on Earth, or at least all attractive women on Earth. He enjoys painting in splattered blood, rainy days, long walks on the beach, thermonuclear devices, and backgammon.

A History Into Microsoft Products

Posted by admin On October - 23 - 2008

Microsoft Windows is the name of several families of software operating systems by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The most recent client version of Windows is Windows Vista. The current server version of Windows is Windows Server 2008.

Windows 1.0 (1985)

The first version of Windows provided a new software environment for developing and running applications that use bitmap displays and mouse pointing devices. Before Windows, PC users relied on the MS-DOS® method of typing commands at the C prompt (C:\). With Windows, users moved a mouse to point and click their way through tasks, such as starting applications.

In addition, Windows users could switch among several concurrently running applications. The product included a set of desktop applications, including the MS-DOS file management program, a calendar, card file, notepad, calculator, clock, and telecommunications programs, which helped users, manage day-to-day activities.

Windows 2.0 (1987)

Windows 2.0 took advantage of the improved processing speed of the Intel 286 processor, expanded memory, and inter-application communication capabilities made possible through Dynamic Data Exchange (DDE). With improved graphics support, users could now overlap windows, control screen layout, and use keyboard combinations to move rapidly through Windows operations. Many developers wrote their first Windows–based applications for this release.

Windows 3.0 (1990)

The third major release of the Windows platform from Microsoft offered improved performance, advanced graphics with 16 colors, and full support of the more powerful Intel 386 processor. A new wave of 386 PCs helped drive the popularity of Windows 3.0, which offered a wide range of useful features and capabilities, including:

Program Manager, File Manager, and Print Manager.

A completely rewritten application development environment.

An improved set of Windows icons.

Windows NT 3.1 (1993)

When Microsoft Windows NT® was released to manufacturing on July 27, 1993, Microsoft met an important milestone: the completion of a project begun in the late 1980s to build an advanced new operating system from scratch.

Windows NT was the first Windows operating system to combine support for high-end, client/server business applications with the industry’s leading personal productivity applications.

PCI DSS and Tape Security

Posted by admin On October - 23 - 2008

PCI DSS

The Payment Card Industry Data Security Standard (PCI DSS) was created as a set of requirements for companies that process, store, or transfer credit card data to make it easier on merchants to adopt sufficient security approved by all credit card companies.

The PCI Security Standards Council develops and maintains the standard. Enforcement of the compliance programs and penalties are established by each individual payment brand.

When evaluating solutions for PCI compliance companies should consult auditors and look for products that offer complete PCI coverage to foresee changes in the standards.

PCI also contains ongoing validation requirements. The most comprehensive requirements include three levels of validation:

1. On-site security audit
2. Self-assessment questionnaire
3. Network scan

The level of validation required, and the frequency of validation efforts, depends upon risk and transaction or account volume.

The Real Cost of a Data Security Breach

Data security breach can cost a company an average of $182 per compromised record in legal fees and other expenses. That’s not including the cost of a damaged reputation, competitive advantage and customers lost due to the breach, and the cost for a lawsuit if charges are pressed. Merchants that store cardholder data also have to worry about the potential fine for non-compliance and the threat of increased fees for transactions.

Here are a few examples of recent major breaches in the retail industry.

TJX

45.6 million credit and debit card numbers were stolen.

DSW Shoe Warehouse

Compromised credit card numbers for about 1.4 million customers and driver’s license information of about 96,000 customers.

Card Systems

Compromised information for 40 million credit card holders.

Marriot International

Compromised credit card information and Social Security numbers of 206, 000 customers and employees.

Polo Ralph Lauren

Compromised 180,000 customer’s credit card information.

Sam’s Club/Wal-Mart

Credit card data belonging to an unspecified number of customers were exposed.

PCI Requirements becoming laws

In May 2007 Minnesota became the first state to make PCI requirements into a state law stating that any company that experiences a data security breach will have to reimburse banks the costs that they incurred blocking and issuing new cards.

How to watch TV on Mac

Posted by admin On October - 23 - 2008

Mac or Macintosh is a brand name for different kinds of computer produced by Apple, Inc. Production of Mac includes all aspects of hardware and own operating system already installed. The Mac is a computer that can run all the major operating systems, including Mac OS X, Windows XP, and Vista.

TV on a PC is in nowadays. How about TV on a Mac?

Widgets are mini-applications that are downloaded and installed to a dashboard for a new function. There are amazing widgets for Mac that will allow us to play TV right on our Mac. There is this viewmy.tv widget that provides access to free Internet television. Besides viewmy.tv, there is also the Ustream.tv for viewing our favorite live stream channels. Before we can download these features, we should first check the system requirements. If we have what are needed to make this application works, we can enjoy watching our favorite shows directly on our Mac.

As we all know, we can’t depend on our Internet connection all the time. Heavy traffic is frequently experienced so we can’t enjoy our favorite show that much. It’s different when we don’t need to download and consume time to have our full view of the channels. But we can have our Macs installed with TV. Aside from widgets, we can enjoy the entertainment of watching TV on our Mac with the help of USB-based tuners like Elgato EyeTV Hybrid that allows us to watch analog and digital TV. Like other common pc, Mac also has its way to have TV on it.

If external devices (USB like EyeTV) do not satisfy us, we can use the PCTV cards like Miglia AlchemyTV Card that is a good choice for computer TV viewing and VHS-to-DVD transferring. It’s a PCI card that requires no additional power supply. We can check miglia.com to check if we have the latest version. After that, set up the PCI card in our Mac, and then install the software using the cd included. To access the newly installed program, we need to restart our Macs and go to the AlchemyTV dialog.

Are Your Staff Members Well Enough Trained?

Posted by admin On October - 23 - 2008

No matter how well the IT infrastructure in your company is designed, you cannot avoid the basic truth that people still play a major role within your organisation.

Every single time the computer system is upgraded – whether it’s a small change to make customer ordering easier or the installation of a whole new system – it’s necessary to follow this by letting all the relevant staff members know of the changes that have been made.

How this process is done can make a big difference to how successfully your staff cope with the changes. Given the basic truth that many people do not like the idea of change, it’s a good idea to give your staff adequate notice of any forthcoming work on the computer system – as much as is humanly possible under the circumstances.

Not only will this give them time to prepare mentally, it will also ensure they have enough time to put in place any other measures or contingency plans that may be necessary to allow business to continue as normal while the IT work is carried out.

But training isn’t just required in times of change. IT training should be a regular part of life at any company if maximum efficiency is to be achieved.

Authorised and Unauthorised Software

Posted by admin On October - 23 - 2008

The bigger your business is, the harder it can sometimes be to keep an eye on what’s happening with your software.

All businesses need software for their computers; the type and amount of software programs required depends largely on the type of business being run and how large it is. But regardless of these issues the problem of whether your software is authorised or unauthorised can rear its ugly head in any business, and it’s important to have adequate measures in place to ensure that any problems associated with unauthorised software are kept to a minimum.

Many employees don’t recognise the problems that can occur when unauthorised software is introduced into the system. Of course the most pressing issue is that of keeping within the law; keeping a copy of the software locked up safely in your software library is perfectly acceptable, but installing that same software on half a dozen computers in a single office is most certainly not.

Could Your IT Department Be More Streamlined?

Posted by admin On October - 23 - 2008

Many companies take on extra staff when business is good, ensuring they have enough people on board to cope with all the tasks that need to be done.

But ‘enough people’ does not always correspond to ‘the right number of people’. Moreover it’s easy for job roles to become blurred, creating an overspill of talent in one area and a shortfall in another.

It’s particularly important for the IT department to be well organised, as so many other areas of a business rely on that department to keep the computer system running at peak performance on a day to day basis. This is why streamlining your IT department is vital to ensure that the right people are always in the right place at the right time.

The first step in the streamlining process is to identify the strengths of the people in the team. Are some people wasted in their job roles? Do others do too little? Finding out what each person does can also highlight any areas of potential weakness which could be exploited if the IT infrastructure were to run into any major problems at any point.

Do You Have Access To Enough IT Staff?

Posted by admin On October - 23 - 2008

No matter how well a business is run and how efficient its computer system is, employees will always run into problems now and again. Whether it’s a simple computer glitch or a major error, it’s good to know you have the right staff on hand to solve the problem in the shortest amount of time possible.

The problem is that you need to know this ahead of time – not when your computers crash and you suddenly realise you don’t have the staff or the resources to cope with it and get things back up and running again.

Not only can this have a detrimental effect on your business, it can also mean that when problems do occur it takes longer for your business to recover. That’s why it pays to review your IT infrastructure and your current needs in order to make sure you are fully prepared and able to take the necessary actions if or when they are ever needed.

Creating A Software Library

Posted by admin On October - 23 - 2008

Every business uses computer software. But not every business realises the importance of having a user friendly software library for cataloging all their software.

While sharing software and using it on more than one computer is against the law, making a copy to keep in your software library in case it is ever needed is not only allowed, it is strongly advised.

In this sense a company’s software library is the computer equivalent of the box that says ‘break glass in emergency’; it grants you access to the vital software your company uses to run its day to day business. If anything goes wrong or the original software is corrupted in any way, you have the back up you need to get you out of trouble.
