We all know them: brute force attacks. Be it SSH, SMTP, IMAP, your favorite web application, ... they happen. And they happen all the time.
Little over a year ago I ordered 2 Yubico U2F security keys, through the Github offer. When they arrrived, I was immediately annoyed by the fact that only Chrome (and Chromium) supported the U2F standard.

While upgrading the Linux kernel on my XPS13, I noticed that I could no longer find the option to enable the ASoC driver that is needed when the sound card is running in I2S mode. The symbol (SND_SOC_INTEL_BROADWELL_MACH) was still there, but it didn't show up at the expected location. I also had all dependencies enabled, so I was a bit surprised it didn't show up. After looking again, I noticed this in the dependencies:
DW_DMAC_CORE [=m]=y
It's not the first time I write about cgroups, but a lot has changed since I wrote that post.
