  • Ultimate Guide to the Processing Language Part I: The Fundamentals (Publication)
    Rapid prototyping and the ability to produce quick visual results are features of many programming languages and frameworks. However, some take it even further by making these their primary goals. Processing, a programming language based on Java, allows its users to code within the context of visual arts and has been designed from the ground up to provide instant visual feedback. In this article, Toptal engineer Oguz Gelal provides a gentle introduction to Processing and some insights into its inner mechanics.
