For development environments with Docker, a fundamental requirement is the synchronization of host folders with a Docker container.
With it, a developer can employ the full power of the host to work on code locally, and instantly see these changes reflected inside the Docker container.
While Docker Compose includes a command to trivially define synchronized folders with the
volume command, development performance is impaired when the docker daemon is not running on the host itself—such as on OS X.
This post aims at giving an overview on the host volume performance impacts when running Docker on a non-Linux host.
This post assumes a basic understanding of the capabilities of Docker and Compose. This preceding post introduces the fundamentals of Docker if you are not familiar with the Docker stack yet.

Docker has gained significant traction and stability since its beginnings in 2013.
My previous experience was that creating complex application containers with multiple services was complicated and full of workarounds.
Since then, Docker has taken over the linking tool Fig into Docker Compose, and has gained an interesting set of abstractions towards container orchestration.
Still, there are many pitfalls regarding Docker use in both development and production.
This post aims at giving an introduction to the possibilities of Docker and its limitations for isolated development environments.

In this post, we extend our database schema with two more tables: Users
and Comments. This will demonstrate the use of relationships between
tables using DBIx::Class.

In this post, we start versioning our database for upcoming changes in
the requirements of our app. To avoid replacing the schema and data
alltogether, we'll employ
DBIx::Class::Migration to create seamless
migration paths for the database.

For my thesis, I'm employing Scrapy as a Crawler
for several Online Social Networks. It provides an extensive pipeline
for scraping, processing and storing pieces of information (or Items).
I found myself using the Item pipeline in a way that it wasn...

In this post we integrate the DBIx::Class schema we created last time
into our Mojolicious blog app.

In this post we create a database schema for our blog with DBIx::Class
and scrape the surface of its capabilities.

In this third post we introduce forms for user login to the blog app and
handling of that login form's GET and POST request data.

In the second post of the series we look into the bascic mechanisms of
routing and rendering within Mojolicous and create the first requests of
Monday, 7. April 2014
This is the first post of a series on the Mojolicous web framework
originating from my experiences at ISP, Fachbereich
Informatik of the
Technische Universität Darmstadt. Step by
step, we will create a simple blogging platform using Mojolicious.
This first post will motivate the use of Mojolicious and provide an
introduction on how to set up a project.
