What is COOL?

COOL - Compact OSADL Online Lectures: Open Source meets Industry

  • COOL is an OSADL webinar series.
  • COOL takes place regularly once a month and covers new and state-of-the-art topics on Open Source software in industry, either on legal or on technical aspects.
  • COOL editions each consist of two lectures covering a special "Open Source meets industry" topic followed by a discussion round. The first "basic" lecture provides basic knowledge with regard to the respective topic and the second "advanced" lecture dives deeper into the topic and highlights special aspects. The discussion round gives all participants the possibility to ask questions and discuss with the respective speakers and the audience.
  • COOL speakers are OSADL experts on the one hand and external specialists on the other hand who kindly agreed to share their expert knowledge on the respective topic.
  • COOL is a virtual event. The lectures are held by live video streams. Speakers will be available for questions and discussion in a video conference which will take part subsequent to the live video streams.
  • COOL in general is designed to provide support how to best and compliantly use Open Source software in industry.

Discussion and possibility to ask questions

Description COOL September 2023 edition:

In the good old days when the GPL and LGPL license texts were drafted, security aspects were less relevant than today. Over the past 30 years, however, the reality of the environmental and usage conditions of embedded systems have changed drastically while the (L)GPL license texts are still the same. So it is not surprising that there are some areas of conflict between these license conditions and today's security requirements. Fortunately there are solutions that have been developed, among other, in an OSADL legal seminar in 2016 and continuously developed and fine-tuned until today.

In the theoretical part of the September COOL edition, Carsten Emde, OSADL, will provide a refresher on the particular obligations that (L)GPL licenses impose with respect to allowing the customer re-installation of the software. In the practical part, Caren Kresse, OSADL, then presents solutions to overcome this perceived dilemma. In the use case part, Christian Johannes, Hirschmann Automation and Control GmbH, will give an example of how a solution was implemented in a real-world embedded system. Thank you, Christian Johannes, for accepting our invitation to contribute to this COOL edition as external speaker.

Recommended audience COOL September 2023 edition:

Open Source officers, software developers and engineers, system integrators, employees of internal legal departments, external legal advisors, purchase department employees who deal with Open Source software, employees of QA departments, etc.
