Introduction To Business Computer Repairs

When it comes to Business Computer Repairs, deadlocks occur when two tasks performed blocking shipments (remain in the send function waiting for the receiver receives the message). If T1 sends a message form T2 and T2 -blocking sends a message equally to either T1 tasks will function both ships being blocked because it can not reach the receive function. It can be solved by rearranging shipping and receiving or using non-blocking or timed deliveries.

The other solution is that tasks can send messages between them. This has the same problems: The priority inversion occurs when a task is dealing with a low priority message and ignores a message of higher priority in the mail.

Although its real-time behavior is more difficult to analyze the traffic signal systems, the message-based systems are usually easier to develop systems to light. The cycle repeats until the client can provide scenarios to deliver. Usually the first delivery cycle is characterized by its length and the large volume of embedded features . After the first start of production, iterations may become shorter (Business Computer Repairs).

Programming as a collective discipline

While focusing on good programming practices, XP recommends a course in short iterations and managed collectively with a constant customer involvement. This leads to a redefinition of the relationship between customer and supplier with surprising results in terms of code quality, timeliness and satisfaction of customer demand.

Extreme Programming is based on five core values: Communication – This is the fundamental way to avoid problems. Practices advocated by the XP require intense communication.

Testing, pair programming and game schedule forcing developers, policy makers and customers to communicate. If a lack appears nevertheless, a coach is responsible for identifying and put these people in touch.

Simplicity

The easiest way of getting the result is better. Anticipate future extensions is a waste of time. A simple application will be easier to change. The feedback is important for the programmer and the client. Unit tests indicate if the code works. Functional tests give the project progresses. Frequent deliveries can test the features quickly.

Some changes require a lot of courage. Sometimes you change the architecture of a project, throwing code to produce a better or try a new technique. Courage can get out of an inadequate situation. It is difficult, but the simplicity, feedback and communication make these tasks accessible.

This value was added in the second edition of Extreme Programming Explained K. Beck. These five values are divided into thirteen practices that are mutually reinforcing. A customer representative shall, if possible, be present throughout the duration of the project.
