We highlight a dangerous pitfall in the state-of-the-art evaluation methodology of deep learning algorithms, as applied in several CPS and IoT application spaces, where collecting data from physical experiments is difficult. The article is inspired by the real experiences of the authors. An extended version appears in the IoT-AE Workshop in conjunction with MILCOM 2022 [1]. Few would disagree today…

Picture credit: Pixabay Machine learning is en vogue, being applied to many classes of problems. One of them is cybersecurity, where ML is used to find vulnerabilities in code, simulate attacks, and detect when an intruder has breached a system's defenses. Ignoring that intrusion detection is an admission of defeat (it comes into play when your system is already compromised!)…

Unlike most disciplines, in Computer Science, conference publications dominate over journals, and program committees carry out the bulk of the peer reviewing. Serving on a PC is a yeoman’s service, and the community owes them a debt of gratitude. However, I believe that a toxic culture has emerged. This blog is a call for PCs to change their priorities. We…

Milan Cathedral is the largest Gothic cathedral in the world Welcome to the trip report on the 28th IEEE International Symposium on Real-Time and Embedded Technology and Applications Symposium (RTAS'22)! For the third time, our travel route does neither include planes nor trains but only a short walk to our desks. Due to the tapering pandemic, the General Chair Nan Guan had to…

A story heard thousands of times “Software complexity is increasing” — I’m sure this is not the first time, nor will be the last time you read this claim. It may sound rhetorical, but repeatedly claiming overtime that software complexity is increasing is nothing but a concrete observation about the incessant pace with which several technological domains are evolving thanks…

"Verified Lustre normalization with node subsampling" by Timothy Bourke, Basile Pesin, Paul Jeanmaire, and Marc Pouzet is the best paper winner of the International Conference on Embedded Software (EMSOFT) in 2021. This blog post gives an overview of the work. The Coq development described in the paper is available online. There is also a page of links between the article…

Introduction Welcome back to a second hands-on blog post in which we explore the implementation of classic real-time concepts in POSIX operating systems. In a previous post, we examined the classic periodic task abstraction and how to implement it in Linux. This time around, let’s explore its equally well-known counterpart: the sporadic task model for event-driven workloads. As we'll compare…

In July, we held another successful ECRTS, with high quality papers, great sense of community, novel concepts, and the same spirit as in previous years. Behind the scenes, however, significant changes happened. The group of persons responsible for the development and organization of the conference, the Executive Board of the Technical Committee of Real-time Systems of Euromicro, has changed, and…

Take 100 lines of C code and a hardware platform. How long will it take for the hardware to execute the code? Being able to construct an answer to this question in the scope of real-time systems is akin to solving one of the Millenium Prize Problems. Of course, the first instinct is to wonder if any loop in the…
