Xhyve – Lightweight Virtualization on OS X Based on Bhyve

Docker Considered Harmful (2016)

I don't think Elasticsearch is a good logging system

Don't Use Protobuf for Telemetry
Protobuf needs no introduction, but this post argues that you shouldn’t use it for telemetry. The basic premise of this post is that a good telemetry library needs to be lightweight to avoid perturbing the application; inefficient diagnostic tools are self-defeating.

Tarsnap: No heartbleed here
There's a few reasons for this. First, the Tarsnap client-server protocol does not use TLS; instead, it uses a protocol which is about 100x simpler (in terms of the number of pages of documentation required to define it). This means there's less code and far fewer edge cases where bugs can lurk without being triggered…
