This document discusses the use of open source tools in software development. It outlines the typical toolstacks used, including programming languages, databases, and frameworks. It notes that open source tools have accelerated startup development by reducing costs and allowing developers greater flexibility in choosing technologies. The document also discusses SAP's embrace of open source, both in powering their own products and services with open source software, as well as contributing their own open source projects.

and the digital televisions and the PCs... we see a
large opportunity of perhaps 3 billion to 4 billion
units per annum, but we see an embedded market
that’s maybe 30 billion to 40 billion units per
annum”
- ARM CEO Warren East

In tegenstelling tot:

21. Purchasingfirst
“Operating systems, databases, web and application servers, devtools all required money. To get anything done, then, developers needed someone to write checks for the tools they needed to build. That meant either raising the capital to buy the necessary pieces, or more often requesting that an employer or other third party purchase them on the developer's behalf.”
Stephen O’Grady –New Kingmakers
