Container Isolation Gone Wrong
One of the main advantages of embracing containers is "lightweight virtualization." Since each container is just a thin layer around the containerized processes, the user gains enormous efficiencies, for example by increasing the container density per host, or by spinning containers up and down at a very fast pace.
However, as the troubleshooting story in the article will show, this lightweight virtualization comes at the cost of sharing the underlying kernel among all containers, and in some circumstances, this can lead to surprising and undesirable effects that container users typically don't think about.
This troubleshooting tale is rather involved. I've started from the basics and worked up to the more complex material in the hope that readers at all levels can get value out of it.

Introducing Agones: Open-source, multiplayer, dedicated game-server hosting built on Kubernetes
In the world of distributed systems, hosting and scaling dedicated game servers for online, multiplayer games presents some unique challenges. And while the game development industry has created a myriad of proprietary solutions, Kubernetes has emerged as the de facto open-source, common standard for building complex workloads and distributed systems across multiple clouds and bare metal servers. So today, we’re excited to announce Agones (Greek for "contest" or "gathering"), a new open-source project that uses Kubernetes to host and scale dedicated game servers.

HHVM 3.25 Released, Now Defaults To PHP7 Mode
Facebook developers working on the HHVM Hack/PHP language stack have released version 3.25 of the HipHop Virtual Machine.
HHVM 3.25's PHP support now defaults to PHP7 rather than the PHP5 mode, which is now in an unsupported state. As expressed previously, Facebook will be focusing more on their Hack language support than PHP7 thanks to all the upstream improvements with PHP 7 especially on the performance front. But the large compatibility with PHP7 will happen to continue at least for the time being. With HHVM 3.25 includes support for PHP7 Throwable/Error/Exception hierarchy, changes to visibility modifiers, and other compatibility work.
