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.

Description COOL March 2023 edition:

There are a large number of recipes to patch the Linux kernel in order to convert it into a real-time operating system. This is straightforward when the vanilla kernel can be used, but there might be a number of issues to make a vendor kernel real-time conformant. But even then, there are many issues that still may go wrong or may not behave as intended; therefore, this COOL edition will cover the long way from a vanilla Linux kernel to an optimized real-time kernel. Nevertheless, this is only half of the work at most, since in addition user space programs must be written in such a way that they take into consideration the particular concept of the Linux PREEMPT_RT kernel. For example, not all system calls may be used at any time, and not all arguments can be used as explained in a function's manpage. Therefore, the second talk of this COOL edition will cover the dos and don'ts when writing userspace real-time applications and exemplify a number of scenarios that real-time programmers may encounter in their daily routine.

Recommended audience COOL March 2023 edition:

Software developers and engineers, hardware developers and engineers, system integrators, field application engineers, etc.
