• Airsick Gaming with the Switch

TL;DR: Anecdotally, the best Switch games to play if you get mildly airsick. The winner is Diablo 3.

• Using fanotify within Docker Containers

I was recently dockerizing tests for a program I’m working on that utilizes fanotify and noticed that the tests, which worked in a VM, were failing to run. Reviewing the logs yielded the culprit: fanotify_init could not be called in the container. TL;DR: you need to run the container with the CAP_SYS_ADMIN capability. But I’m new to the Linux kernel and wanted to know why this was necessary.

• Dumpster Diving through Namecoin and Emercoin

I was at Defcon 27 recently and saw a talk titled “Secrets Worlds in Plain Web. The BlockChain DNS.” by Fernando Amatte. He spoke about blockchain based DNS infrastructure, specifically Namecoin and Emercoin, as a means of hiding secrets in plain view. I missed the beginning of the talk, but I don’t recall him presenting any specific examples of people using blockchain DNS services. This gave me a few questions:

• Is anyone using these blockchain DNS services?
• What are they using them for?
• Are any interesting services “hiding in plain site?”
