Dear Hannah Wolfe,

in your tweet you say you'd like to know why we need a database cluster for our blog. Thanks for that question, I'm happy to respond.

Every now and then, every piece of hardware fails. That's why we employ clusters for every server app we are running and go to length to avoid single points or failure.

Our cluster is built on the idea of immutable infrastructure. Our apps run inside Docker containers. When a node in our cluster fails, the containers running on that node are started on a different node. In the meantime, identical instances of the apps running on other machines handle the requests.

This principle is common for stateless applications, but we also want it to be valid for databases. To avoid having a database server be a single point of failure, databases must be run on clusters which share parts of their data.

Dear users,

we have an important question for you regarding the improvement of one aspect of our product.

When you create a service on Giant Swarm using the service definition (usually in a swarm.json file), after creation of the service you currently can't modify your service.

We know that many of you want this to change. The question is, how would you like this to work?

1) Submitting new swarm.json

This is an unofficial manual for the couchdb Python module I wish I had had.

Installation

pip install couchdb

Importing the module

marians

function(doc) {
  if (doc.request_context.user_name
    && doc.timestamp
    && doc.day
    && doc.request_context.activity
    && typeof doc.request_context.activity !== "undefined") {
    var is_error = 0;
    if (typeof doc.response_status !== "undefined" && doc.response_status > 400) {
      is_error = 1;
    }

Getting Started with a D1 mini (ESP-8266EX) and Arduino

These notes from June 2016 document how I got a successful start with a Wemos D1 mini on Arduino (Mac).

Installation

USB Serial Connection

I'm on Mac OS Sierra, so I need a driver for the USB serial bridge on the board, which is a CH340. The driver can be downloaded from this page:
