You first figure out which integer has the largest bit size. You then generate a random number large enough to hold the same number of bits as the largest of the two integers. The actual crossover is performed by the crossover_when method. The idea is that you ll pass in a block that will be called with the index of the current bit. If the block returns true, you ll switch which source you re currently reading bits from. You ll keep reading bits from that source until the next time the block returns true.

For this project, we implemented an extremely simple authentication system. While this works for the simple needs of a single user who doesn t require any advanced functionality, there is definitely room for us to expand it. For one thing, it would be nice if we could store the passwords in the database instead of simply storing them in our code that way, we could build a simple web form in the administration section so we could change it on a regular basis. Browse through the source of the restful_authentication plug-in for ideas on how to expand your authentication code.

XML, or eXtensible Markup Language, is a standard for creating tagging languages to wrap up data so that programs can easily read and write it. XML supplies the structure, and related standards called document type definitions (DTDs) define which tags take which attributes and which tags can be nested within other tags. Although XML implementations can be quite complex, MythTV s uses of XML are relatively simple, and you can figure out most of what you need to know to modify a theme by looking at the XML. Here s the short set of rules. A word between angle brackets is a tag (for example <window>). If there are other words, with an equals sign followed by either a number or a quoted string, these are attributes belonging to that tag (for example <window name="programguide">). Each tag has a closing tag (for example <window name="programguide"></window>). Other properties of this can be specified in between the opening and closing tags (for example <window name="programguide"><font name="title" face="Trebuchet MS"></font></window>). A tag can be both an opening tag and a closing tag by having a forward slash before the closing angle bracket (for example <window name= "programguide"/>). A closing tag must be for the last tag that was opened (or the file is invalid).

You can get away with using the notion of switching because the probability of a switch each time is always 50 percent, so in the end it s no different than randomly selecting a source for each bit. But the real reason you ve implemented it this way is to make it easier to implement another kind of crossover. So far you ve been using uniform crossover where each bit can be randomly selected from either parent. What if, instead, you took whole chunks of bits from one parent or the other
