The difference between hobbyists and professional developers, besides their ability to teamwork quite often, is their knowledge and familiarity with the tools used in modern software development. The presentation will have a look at which categories of tools are used today, why those tools are used, and how quality, understanding, and cooperation can be improved by using various tools. The presentation aims to provide an overview of the tools-landscape, and to rebut the often heard claim: "real developers just need a text editor".
