Last weekend I had the pleasure of attending FOSDEM 2017. For many years, it is probably the most exciting event exclusively on Free Software to attend every year.
My personal highlights (next to meeting plenty of old and new friends) in terms of the talks were:
20 Years of Linux Virtual Memory by MM-Guru Andrea Arcangeli
GPU-Enabled Polyphase Filterbanks by Jan Kraemer
Secure Microkernel for Deeply Embedded Devices by Jim "jserv" Huang
A discussion of Fedora's Legal state by Tom Callaway
Radio Lockdown Directive by Max Mehl
I was attending but not so excited by Georg Greve's OpenPOWER talk. It was a great talk, and it is an important topic, but the engineer in me would have hoped for some actual beefy technical stuff. But well, I was just not the right audience. I had heard about OpenPOWER quite some time ago and have been following it from a distance.
The LoRaWAN talk couldn't have been any less technical, despite stating technical, political and cultural in the topic. But then, well, just recently 33C3 had the most exciting LoRa PHY Reverse Engineering Talk by Matt Knight.
Other talks whose recordings I still want to watch one of these days:
