Last September I gave a talk at EuroBSDcon in Paris. It was about the VPN setup for connecting the branch offices of my employer.

It was not my first EuroBSDcon but the first time I delivered a talk! I feared that only few people will show up at to my talk since Michael W. Lucas had his talk at the same time and also covered an OpenBSD topic. But the room was full and my talk was well received.

After the talk I received a nice gift from the EuroBSDcon organizers: a cartoonist made drawings from the presenters during the talks!

The new code depends, of course, on the corresponding firmware package, ported by Patrick which can be installed using a very recent fw_update(1). Of course, this all plays into the recently revealed problems in Intel (and other) CPUs, Meltdown and Spectre.

ITWire has published an article regarding Theo de Raadt's (deraadt@) reaction to the Meltdown/Spectre disclosures.

One choice quote reads:

Intel engineers attended the same conferences as other company engineers, and read the same papers about performance enhancing strategies – so it is hard to believe they ignored the risky aspects.
