by Thorsten Liebig At: FOSDEM 2019 https://video.fosdem.org/2019/AW1.125/openems.webm openEMS is an electromagnetic field solver using the FDTD method. The tool can be used to design and understand the electromagnetic behavior of antennas, filters, PCBs and more. It has an Octave (or Matlab) and Python interface to setup and analyze the simulation model. This allows for a great flexibility and the possibility to integrate or interface to other software. The talk will give a short introduction...

A new network administrator is hired, and while going around, he notices that the app is making network calls to an unknown external endpoint. After some investigation, it’s found that this app has been sending for years confidential data to a competitor (or a state, or hackers, whatever). This is awkward. Especially since it could have been...

by Akihiro Suda and Giuseppe Scrivano At: FOSDEM 2019 https://video.fosdem.org/2019/UA2.114/containers_k8s_rootless.webm Kubernetes supports several security mechanisms such as Seccomp, Apparmor, SELinux, and runAsUser for protecting the hosts from container-breakout attacks. However, these mechanisms are not sufficient for the security demand because Kubelet and CRI/OCI runtimes require the root privileges on the hosts, and these components are seriously bug-prone. The dependency on the root...
