The more I use Docker, the more I notice it being used. One interesting example was when I recently decided to add a Discourse site to jeffknupp.com (it's not ready yet, but will be soon). When I finally found instructions for installing a self-hosted version of Discourse (rather than their SaaS hosted version that requires a monthly payment), I was shocked.
There have been a number of technology innovations in the field of software development over the last five or ten years. Cloud computing, Hadoop, and NoSQL are just a few technologies that have seen reasonably quick growth and adoption. But in terms of long-term effect on the software industry, these technologies are miles behind a relative newcomer.
That technology is docker.
class is a fundamental building block in Python. It is the underpinning
for not only many popular programs and libraries, but the Python standard library as
well. Understanding what classes are, when to use them, and how they can be
useful is essential, and the goal of this article. In the process, we'll explore
what the term Object-Oriented Programming means and how it ties together with
Much of my work recently has been focused on API creation (REST APIs in particular) and, in my spare time, trying to push the boundaries of ORM usage (through sandman). While I once believed these to be entirely separate pursuits, now I'm not so sure. Thinking about all the REST API hype, and hypermedia's neglected client, perhaps the two are more closely intertwined than I thought.
Most of the population of people who have read Roy Fielding's dissertation tell us that, while we may understand HTTP verbs, we don't know anything about hypermedia. Our REST APIs, they say, are not really RESTful, and certainly do not exhibit Hypertext As The Engine Of Application State, or HATEOAS. The fact that we have APIs you need to read documentation to understand is a clear signal, they tell us, that the client is using out-of-band information to navigate the server. Hypermedia, they say, is the answer. We simply embed enough information in our responses that the client can intelligently choose what action to take next using only the contents of the HTTP response.
Why This Is Tremendously Stupid
