Squeak Smalltalk is wholly unlike any other open source programming tool you’ve worked with – and mostly in good ways. Unfortunately, it’s the bad ways that make the first impression. This hands-on tutorial will help you get past the unfamiliar and the unwieldy so that you can take advantage of the elegant and productive environment that lies underneath. We’ll cover what makes Smalltalk so wonderful: the “turtles all the way down” approach to language design, the highly integrated code browsers, object inspectors, and debuggers, the accessibility (and hackability) of every piece of library code, the built-in refactoring and unit testing support, and the extreme dynamicity and portability of the environment. But we’ll also address the practical concerns that keep people away from Squeak: how to get rid of the pastel colors and bitmapped fonts so that you can stand to look at it; how to get your source code into version control so you can collaborate with others; how to find documentation and examples; how to integrate with the OS and with C libraries; how to manage deployment.

Draw es un potente programa de dibujo que crea gráficos vectoriales orientados a objetos, es decir, por mucho que se amplíen mantienen su calidad. Los gráficos vectoriales están orientados tienen algunas ventajas sobre los de mapas bit: permiten la edición individual de cada elemento, pueden cambiarse de tamaño sin pérdida de calidad y se pueden almacenar usando menos bytes. Draw es un componente de OpenOffice, lo que nos permite conseguirlo de forma gratuita así como copiarlo y distribuirlo, a diferencia de los programas propietarios.

Most open source work is done in C or C++, often using tools developed decades ago. It’s too difficult for most people to download the source and build an open source project and those that could do it often don’t feel they have the time or patience to do it. In the Squeak environment, there is no build process, and no long waits for recompilation, nor do you have difficulty jumping into a running system to find out what is happening. Programming happens at a much higher level of abstraction in Squeak Smalltalk. Due to difficulties with C and C++ most people see open source programming as a badge of hacker machismo. Old Smalltalkers, and the new breed of Squeakers can be forgiven for asking, “Why do you people keep torturing yourselves when there’s a better way?”
