Lutz provides a fast and small port scanner with stealth scanning and OS detection.
Lutz is a fast and small stealth port scanner, similar to nmap. It has the most popular scanning options (SYN, FIN, XMAS Scan, PROTO Scan, etc.) and simple OS detection.
It supports some very beta idle scanning and several other options. It can also scan subnets, or scan a list of hosts specified in a file.
Enhancements:
- FIxed a Bug in the get_host_list() function. You got an segmentation fault when not specifying ports on the command line. Now you wont :)

This chapter serves as a gentle introduction to Maypole and setting up Maypole applications. We look at what Maypole is, how to get it up and running, and how to start thinking about building Maypole applications.

What is Maypole?

Presumably you have some idea of what Maypole is all about, or otherwise you wouldnt be reading this manual. But Maypole is good at many different things, and you may have accidentally focussed on one aspect of Maypole while missing the big picture.

For instance, you may know that Maypole is extremely good at putting web front-ends onto databases. This is true, but its only a part of what Maypole does. You may have heard that Maypole is a web application framework, which is true, but it doesnt mean very much. There are a huge number of things that Maypole can do, because its very much a blank slate. You can make it do what you will. In this manual, well be making it act as a front-end to a database, as a social network site, as an intranet portal, and many other things besides.It is a framework.

I like to think that Maypole is a way of going from a URL to a method call to some output. If you have a URL like /product/order/12, Maypole is a way of having it load up product number 12, call an order method, and produce a page about what its just done. The reason Maypole is such a big deal is because it does all this for you. You no longer have to care about your web server. You hardly have to care about your database. You dont have to care about templating modules, parsing CGI parameters, or anything else. You only need to care about business logic, and the business logic in this instance is how you order a product, and what you need to display about it once youve done so. This is what programming should be: only caring about the work that distinguishes one program from another.

It does this using a technique called MVC for web applications.

What is MVC for web applications?

Maypole was originally called Apache::MVC, reflecting its basis in the Model-View-Controller design pattern. (I had to change it firstly because Maypole isnt tied to Apache, and secondly because Apache::MVC is a really dull name.) Its the same design pattern that forms the foundation of similar projects in other languages, such as Javas Struts framework.

This design pattern is found primarily in graphical applications; the idea is that you have a Model class which represents and manipulates your data, a View class which is responsible for displaying that data to the user, and a Controller class which controls the other classes in response to events triggered by the user. This analogy doesnt correspond precisely to a web-based application, but we can take an important principle from it. As Template Toolkit author Andy Wardley explains:

What the MVC-for-the-web crowd are really trying to achieve is a clear
separation of concerns. Put your database code in one place, your
application code in another, your presentation code in a third place.
That way, you can chop and change different elements at will,
hopefully without affecting the other parts (depending on how well your
concerns are separated, of course). This is common sense and good practice.
MVC achieves this separation of concerns as a by-product of clearly
separating inputs (controls) and outputs (views).

This is what Maypole does. It has a number of database drivers, a number of front-end drivers and a number of templating presentation drivers. In common cases, Maypole provides precisely what you need for all of these areas, and you get to concentrate on writing just the business logic of your application. This is one of the reasons why Maypole lets you develop so rapidly: because most of the time, you dont need to do any development at all.

Class::InsideOut::Manual::About is a guide to this and other implementations of the inside-out technique.
This manual provides an overview of the inside-out technique and its application within Class::InsideOut and other modules. It also provides a list of references for further study.
Inside-out object basics
Inside-out objects use the blessed reference as an index into lexical data structures holding object properties, rather than using the blessed reference itself as a data structure.
$self->{ name } = "Larry"; # classic, hash-based object
$name{ refaddr $self } = "Larry"; # inside-out
The inside-out approach offers three major benefits:
- Enforced encapsulation: object properties cannot be accessed directly from ouside the lexical scope that declared them
- Making the property name part of a lexical variable rather than a hash-key means that typos in the name will be caught as compile-time errors (if using strict)
- If the memory address of the blessed reference is used as the index, the reference can be of any type
In exchange for these benefits, robust implementation of inside-out objects can be quite complex. Class::InsideOut manages that complexity.
Philosophy of Class::InsideOut
Class::InsideOut provides a set of tools for building safe inside-out classes with maximum flexibility.
It aims to offer minimal restrictions beyond those necessary for robustness of the inside-out technique. All capabilities necessary for robustness should be automatic. Anything that can be optional should be. The design should not introduce new restrictions unrelated to inside-out objects, such as attributes and CHECK blocks that cause problems for mod_perl or the use of source filters for syntatic sugar.
As a result, only a few things are mandatory:
- Properties must be based on hashes and declared via property
- Property hashes must be keyed on the Scalar::Util::refaddr
- register must be called on all new objects
All other implementation details, including constructors, initializers and class inheritance management are left to the user (though a very simple constructor is available as a convenience). This does requires some additional work, but maximizes freedom. Class::InsideOut is intended to be a base class providing only fundamental features. Subclasses of Class::InsideOut could be written that build upon it to provide particular styles of constructor, destructor and inheritance support.

ROX-All is a single archive containing launchers for most of the ROX applications.

It contains everything you need to get started with ROX, a GTK desktop based around the file system.

Because actually putting all the software in this archive would make it very big and quickly out of date, it will download the latest versions of programs when you run them the first time.

Therefore, you will need a network connection (but only when downloading or upgrading programs).
