PatternLayout"> <param name="ConversionPattern" value="Tracer %m%n" /> </layout> </appender> The XML element appender requires two attributes: name and type The name attribute is a user-friendly name of the message destination that s referenced in the logger or root XML tags The type attribute is a class name that s loaded when a message is generated For most cases, you ll use a log4net-defined implementation, but you could reference a custom class by implementing the proper interfaces In the example, the class name log4netAppender ConsoleAppender references an appender that generates a message on the console The following appenders are defined within the log4net package (note that all class names are prefixed with the namespace log4netAppender): ADONetAppender: Appends the data to a SQL database using the ADONET API You append the data using a prepared SQL statement or stored procedure ASPNetTraceAppender: Appends messages to an ASPNET trace context.

To reduce the footprint of mail services, you should also limit the number of protocols in use on your server. To do so, click the Settings tab for the Mail service in Server Admin, and verify you are using only the services you need (see Figure 13-27). For example, many environments will use only POP or IMAP. If you aren t using one of the two protocols, then disable the other (for a more in-depth discussion of POP, IMAP, or SMTP, see 5).

The speed of the motor is controlled by pulse width modulation (PWM), as shown in the diagram in Figure 3-5. The motor power is rapidly turned on and off over a time interval. The speed of a motor depends on the average voltage applied to it, and the PWM method is a way of controlling this average voltage. It is energy efficient because the transistors are either completely off or on.

Note Mac OS X runs Apache 2.2. You can review any module on the Apache vulnerabilities site at http://

BufferingForwardingAppender: A special type of forwarder that propagates the messages as events The events are sent when you define a condition ColoredConsoleAppender: The messages are appended to the standard output, or standard error output, but you can color or highlight specific message priorities Remember that not all consoles support all color codes..

Figure 3-5. PWM for motor at power level of 35% With the standard firmware, the length of the whole cycle is 128 s. This corresponds to 7,800Hz, which is an audible frequency that can sometimes be heard as a high-pitched whistling sound coming from the motor. For the NXT, the relationship between the motor speed and the applied voltage is linear. We ll describe all that in more detail in 12. The available current on the output ports is approximately 800mA for port A and 500mA for B and C. The output driver is equipped with thermal protection that limits the current if it is overheating.

PHP Hypertext Preprocessor (PHP) is a programming language that allows web developers to create dynamic content that interacts with databases. PHP is most often used for developing web-based software applications. Not all web sites use or need PHP. For web servers with sites that do not need PHP, you can leave the module disabled. But if you need to enable it because you are developing PHP code for the site, then you can do so by removing the commenting from the line in the httpd.conf file that loads the PHP module. You can do this by finding the following line and removing the # in front of it: #LoadModule php5_module to look like the following: LoadModule php5_module libexec/httpd/libphp5.so libexec/httpd/libphp5.so

The Book class declaration has to have an associated relational database table. The associated table could be a view, but that is a choice for the developer. In the Book example, the table is called BOOKS, and is defined as follows: CREATE TABLE "BOOKS" { "ISBN" VARCHAR(20) NOT NULL, "TITLE" VARCHAR(120) NOT NULL, "AUTHOR" VARCHAR(50) NOT NULL, PRIMARY KEY( "ISBN") }; The table BOOKS has three columns, which are all varchar, or variable length strings, that can t contain null values. The primary key index is ISBN, and it s expected to be unique. When using NHibernate, it isn t necessary for a table to declare a primary key.

Note Perl, a scripting language discussed later in the chapter, can be disabled in the same manner:

This is the ground pin. Usually pins 2 and 3 are connected together in sensors, but not in motors. If a sensor is accidentally connected to an output port, the driver will be partially short-circuited. Fortunately, the driver is well protected, but it is a good idea to avoid this situation.
