Integrating Eiffel in to a COM environment is remarkably easy as the tools that handle the majority of the heavy lifting related to COM development already exist. Programming dynamically with COM is very different than programming statically with Eiffel so I've included common pitfall concept translations for these instances.

Having looked at code for interfacing Eiffel to C and creating callbacks from C to Eiffel, I frequently found that things were not done properly, resulting in potential memory corruption or crashes.

Using a C/C++ external in an Eiffel system is pretty easy. Simply do a C/C++ inline and provide the arguments to the C/C++ externals.

When transforming the same system into a multithreaded application one has to pay attention to something else: C/C++ externals that may take a long time to execute.

This is a short tutorial for building web applications with Goanna

It covers the following topics

• Installing all the software you need
• Getting to know Goanna
• A short description on how to develop a web application with Goanna

How it all works

Goanna offers many different services and layers of abstraction.

Since some time Eiffel supports a serialization method completely written in Eiffel. It directly supports serialization to a file or to memory. This example shows how to use this to serialize an arbitrary object structure to a string.

On Unix/Linux a daemon is a program that runs in the background independent from the logged in user.

The way to achieve this is normally to directly fork after the execution and let the parent process exit. This results in the child process having lost its parent which leads to the init process automatically inheriting this process.
