Persistence makes you capable

During my research of operating systems kernels, I got side tracked towards security mechanisms in operating systems and their kernels.

An operating system design

Conversations in #Ada on IRC yesterday turned back to developing an OS in Ada, this has actually been a goal of mine for some time.

New hosting

Well, there were problems with my last web host, so I closed down that site and shifted everything over to a new host in the US.

Restarting work on ANTLR's Ada95 Target

Well, I've begun to look at the ANTLR source and the source I started writing for the Ada95 language target and I'm getting to the point where I'm seeing problems with the Java implementation again.

Interfacing to C from Ada95

In this tutorial I will take you through the steps of interfacing to C variables and functions.

Dot notation for tagged types

Using the code from the interface types tutorial, we can now use the dot notation provided by Ada 2005.

Interface types

Carrying on from the abstract types tutorial, the natural progression is to add multiple inheritance.

Abstract types

This tutorial will show you what an abstract type is in Ada. I will also provide information on how the Ada type equates to the C++ class.

An abstract type provides the "specification" for a family of a user defined types.

wxAda: an Ada95 binding to wxWidgets

wxWidets was a piece of software I was using at work, I liked it so much that it made it's way into my home projects.

As I was using wxWidgets a lot, I was getting rather annoyed with C++.

Dreamcast

Whilst working for a games company I ported one of their games to the Dreamcast without the use of an official development kit (which was called Dolphin/Katana), I used the freely available tools.

The game was very slow due to the fact that it was all done in 2D, there was no 3D interface f
