A class s having more errors than average is a warning sign A few error-prone classes tend to be the most expensive part of a program If you have a class that has had more errors than average, it will probably continue to have more errors than average Think about rewriting it If programming were a science, each warning sign would imply a specific, welldefined corrective action Because programming is still a craft, however, a warning sign merely points to an issue that you should consider You can t necessarily rewrite tricky code or improve an error-prone class Just as an abnormal number of defects in a class warns you that the class has low quality, an abnormal number of defects in a program implies that your process is defective A good process wouldn t allow error-prone code to be developed.

By default, when an application is first loaded onto the emulator or the actual device, it is associated with the Unfiled category. It can be assigned to a Palm OS or user defined category. An application that is not assigned a category will only display under the Unfiled and All category. To move the HiSmallWorld application to a different category, push the Menu button on the device and select the Category... menu option (see figure 8.23).

It would include the checks and balances of architecture followed by architecture reviews, design followed by design reviews, and code followed by code reviews By the time the code was ready for testing, most errors would have been eliminated Exceptional performance requires working smart in addition to working hard Lots of debugging on a project is a warning sign that implies people aren t working smart Writing a lot of code in a day and then spending two weeks debugging it is not working smart You can use design metrics as another kind of warning sign Most design metrics are heuristics that give an indication of the quality of a design The fact that a class contains more than 7 members doesn t necessarily mean that it s poorly designed, but it s a warning that the class is complicated.

Similarly, more than about 10 decision points in a routine, more than three levels of logical nesting, an unusual number of variables, high coupling to other classes, or low class or routine cohesion should raise a warning flag None of these signs necessarily means that a class is poorly designed, but the presence of any of them should cause you to look at the class skeptically Any warning sign should cause you to doubt the quality of your program As Charles Saunders Peirce says, Doubt is an uneasy and dissatisfied state from which we struggle to free ourselves and pass into the state of belief Treat a warning sign as an irritation of doubt that prompts you to look for the more satisfied state of belief.

Note that, in general, using hints to override the optimizer's choice of plan should be the last resort when dealing with performance issues. A hint is not a kind gesture; rather, you force the optimizer to use a particular route in optimization. If you introduce a hint in production code, that aspect of the plan becomes static (for example, the use of a particular index or a certain join algorithm). The optimizer will not make dynamic choices to accommodate changes in data volume and distribution. There are several reasons that the optimizer might not produce an optimal plan and why a hint can improve performance. First, the optimizer doesn't necessarily generate all possible execution plans for a query. If it did, the optimization phase could simply take too long. The optimizer calculates a threshold for optimization based on the input table sizes, and it will stop optimizing when that threshold is reached, yielding the plan with the lowest cost among the ones it did generate. This means that you won't necessarily get the optimal plan. Second, optimization in many cases is based on data selectivity and density information,
