K8s on (vanilla) Raspbian Lite

Yes - you can create a Kubernetes cluster with Raspberry Pis with the default operating system Raspbian. Carry on using all the tools and packages you're used to with the officially-supported OS.

Pre-reqs:

• You must use an RPi2 or 3 for Kubernetes
• I'm assuming you're using wired ethernet (Wi-Fi also works)

Configure Synology NAS as Git Server

Instructions for setting up a git server on a Synology NAS with Diskstation. Specifically, I am using a DS414 with DSM 5.0.

Set Up User and Folder

• Create user gituser via Diskstation interface (with File Station and WebDAV privilages)
• Add new shared folder called git (located at /volume1/git) with read/write access for gituser and admin. This folder will hold all the repos.
• Install Git Server package via Diskstation

Local SSL websites on macOS Sierra

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on macOS Sierra, but they have been known to work in El Capitan, Yosemite, Mavericks, and Mountain Lion.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward the edit command to Sublime Text:

alias edit="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"

Self isolating binaries

This is a play proposal for a new wrapper around go build that would build your binary but wrap it in code that would prepare isolation around your binary on run.

A concept of this is in https://github.com/jfrazelle/binctr, in that it takes a docker image and embeds the contents into a final binary so you have a self-contained binary.

The binctr example is unnessesarily heavy for go binaries because all you need is a completely static binary.
