5. The fact that successful assignment of some value v to some variable V makes the comparison V = v evaluate to TRUE is known as The Assignment Principle. Although it sounds trivial, that principle has far-reaching consequences (unfortunately beyond the scope of the present chapter). 6. It can t hold less than one, either! so long as it s in existence. In other words (although the point is somewhat tangential to the main purpose of this chapter), I reject the concept of uninitialized variables.

It follows from the definition that a value might equally well be called a constant, and we do indeed usually take the terms to be equivalent. On occasion, however, it s useful to have a term for a variable whose value by design never changes, and the term constant is sometimes used for this purpose. The terms constant and value are thus (usually) interchangeable. By contrast, the terms constant and literal aren t! A literal isn t a value, it s a symbol that denotes some value (yet another logical difference here namely, that between notation and denotation). The value in question is determined by the symbol in question (and since every value is of exactly one type, the type of that value is also determined by the symbol in question a fortiori). Loosely, we can say that a literal is self-defining. Here are some Tutorial D examples: FALSE 4 2.7 'ABC' P# ('P1') CARTESIAN ( 5.0, 2.5 ) /* /* /* /* /* /* a a a a a a literal literal literal literal literal literal of of of of of of type type type type type type BOOLEAN INTEGER RATIONAL CHAR P# POINT */ */ */ */ */ */

These include removing temporary files, performing backups, reviewing drive capacity, checking how long you ve been logged into your computer, and checking network statistics Mac OS X uses three main maintenance scripts that log data into separate files These are known as periodic scripts They include daily, weekly, and monthly You can manually run these periodic scripts by using the periodic command For example, to run the daily periodic script, use the following command:.

Figure 7-1 shows the JavaServer Pages (JSP) page /app/bankaccount.jsp. If either maryjane or cgross wants to access their bank account, each would need to perform a login, and an HTTP cookie would be associated with each login. Then both cgross and maryjane would access their bank account information from the same URL. This is a bad way of designing a URL for the following reasons: A user can use only one data set, because there is no way for an administrator to exist: For example, a user with multiple accounts would not be able to access all the accounts, unless you write code that aggregates the controlled accounts. Using a unique URL with a Web service, users can aggregate the accounts themselves. Security is put into the hands of the Web application developer: The Web application developer must add barriers to ensure that only authorized people are allowed access to certain pieces of information. All too often, however, the barriers can result in security problems. HTTP security is well known, well defined, and stable, and those who manage it administrators are well aware of any security holes. Programmers, although capable and intelligent, are not security specialists.

Following on from the previous point, it s worth noting too that distinct literals can denote the same value. For example, the following are three SQL literals of type TIME WITH TIME ZONE that all denote the same absolute value (viz., 6:00 pm London time, which is the same as 10:00 am San Francisco time and 8:00 pm Helsinki time): TIME '18:00:00-00:00' TIME '10:00:00-08:00' TIME '20:00:00+02:00' /* London */ /* San Francisco */ /* Helsinki */

You can configure the periodic scripts to log more data than they do with the default settings. You can configure the manner with which periodic runs the daily scripts using the periodic.conf file located at /private/etc/defaults. You should make some minor adjustments to the periodic.conf file to increase the logging of events. These include the following: Change the NO in the lines for weekly_show_badconfig="NO" and monthly_show_badconfig="NO" to YES to have a periodic report of when there is bad configuration data found by the monthly.out file.
