Yes, I work for Apcera and linux-toys.com is my personal blog where I talk about open source technologies (mainly Docker lately) and software that I develop. Like the article states, I am a Docker fanboy and want them to be great again. The blog website is actually running on a four node Raspberry pi cluster that I referenced in the blog as a link. The reason I joined Apcera is because they are also developing cool container technology. Until recently, Apcera was only available to enterprises and didn’t have a solution for “homeduction” users like me to host and run applications like my blog and a few other services. With the community edition of the software, I can gather a few spare x86 boxes and make the switch. I will still be running the same Docker images but using Apcera’s orchestration software instead of swarm.
Your submission page is heavy on the linux-toys.com domain, implying that it's yours. That same site identifies the author as working at Apcera.
There is also a submission in your account that points directly to an Apcera blogpost, with the same author name.
Disclosure: I work for Pivotal, we donate the majority of engineering to Cloud Foundry. Apcera has beef with us.
