LightTPD maintains an access log, an error log, and a PID file, which all tell you something about the server s status. Most system and application logs can be found in the /var/log directory, so a good place to keep the access and error logs is /var/log/lighttpd/. For LightTPD to be able to write to these directories, you must first create the directories, and then change the access rights, as follows: $ sudo mkdir /var/log/lighttpd $ sudo chgrp lighttpd /var/log/lighttpd $ sudo chmod g+rw /var/log/lighttpd The access log is where LightTPD keeps a log of all requests that have been made to the server. Among other things, the access log is useful for generating usage reports with, for example, AWStats (http://awstats.sourceforge.net/) and Webalizer (http://www.mrunix.net/ webalizer/). You tell LightTPD where to write the access log data with the accesslog.filename setting in the configuration file (Listing 12-1). A typical entry in the access log might look like this: qr code generator with logo javascript Java QR Code Generator - zxing example - JournalDev

The following are typical entries in this log: 2006-06-06 09:57:50: (log.c.133) server stopped 2006-06-06 09:58:19: (log.c.75) server started The location of the PID file is specified with the server.pid-file setting in the configuration file. The PID file is created by LightTPD at startup, and it contains the process ID of LightTPD. The file should be located in the /var/run directory, along with PID files of other processes. 1 <= number <= 10 The and operator is a so-called Boolean operator. It takes two truth values, and returns true if both are true, and false otherwise. You have two more of these operators, or and not. With just these three, you can combine truth values in any way you like: if ((cash > price) or customer_has_good_credit) and not out_of_stock: give_goods() Note If Magento s documentation is too confusing, use PHP s get_class_methods to see what available We run the tests again, and seeing them passing, open the browser and check that the page looks fine there, too, as shown in Figure 2-3. The Boolean operators have one interesting property: They only evaluate what they need to. For example, the expression x and y requires both x and y to be true; so if x is false, the expression returns false immediately, without worrying about y. Actually, if x is false, it returns x otherwise it returns y. (Can you see how this gives the expected meaning ) This behavior is called short-circuit logic: the Boolean operators are often called logical operators, and as you can see, the second value is sometimes short-circuited. This works with or, too. In the expression x or y, if x is true, it is returned, otherwise y is returned. (Can you see how this makes sense ) So, how is this useful Let s say a user is supposed to enter his or her name, but may opt to enter nothing, in which case you want to use the default value '<unknown>'. You could use an if statement, but you could also state things very succinctly: java qr code generator library Read QR Code content with Selenium and zxing – Elias Nogueira ...
