In this blog post, I’m going to show you how to test Kubernetes locally on OSX/macOS. Testing Kubernetes without having access to a cloud operator in a local lab is not as easy as it sounds. I’d like to share some of my experiences in this adventure. For those who have already experienced in Virtualbox & Vagrant combination, I can tell you that it doesn’t work. Since Kubernetes will require virtualization, setting another virtual environment within another VirtualBox has several issues. After trying to bring up a cluster for a day or two, I gave up my traditional lab and figured out that Kubernetes has an alternate solution called minikube.

Installation

If your OSX/macOS doesn’t have brew I strongly recommend …

In this post we describe MySQL connections, user threads, and scaling. We hope that an increased understanding of how MySQL works will help application developers and system administrators to make good choices and trade-offs.

I remember wanting to create MySQL Cluster sandboxes several years ago. By then, however, MySQL-Sandbox technology was not flexible enough to allow an easy inclusion, and the cluster software itself was not as easy to install as it is today. Thus, I kept postponing the implementation, until I started working with dbdeployer.

I included the skeleton of support for MySQL Cluster since the beginning (by keeping a range of ports dedicated for this technology, but I didn’t do anything until June 2018, when I made public my intentions to add support for NDB in dbdeployer with issue #20 (Add support for MySQL Cluster)). The issue had just a bare idea, but I needed help from someone, as my expertise with …

Facebook Reality Labs (FRL) is using groundbreaking 3D capture technology and AI systems to create lifelike virtual avatars. The technology could one day make social connections in virtual reality as natural and common as those in the real world.

Facebook has worked on virtual avatars for several years. At F8 2016, Facebook Chief Technology Officer Mike Schroepfer introduced new avatars for Facebook Spaces, replacing the floating blue head in use at the time with an updated model featuring new facial features and lip movement. At F8 last year, he debuted Facebook’s efforts into more lifelike avatars being developed by FRL Pittsburgh. In the brief demo, audiences saw two realistic digital people animated in real time by members of the team.

The FRL team has made significant progress in the two years since Schroepfer debuted …
