Somehow I came across a good example of applied hexagonal architecture in JavaScript, it's César Alberca's blog. He has all the source code on github.

Archijs describes itself as "A package to test javascript architecture".
TL;DR - it is not ready for use yet, I would not.

What advice/rules I may give to junior developers about the Ruby on Rails app design? This article is not only relevant for Rails developers, but also very general. I feel that rails devs need more support here, because Rails makes it especially hard to use magic.
Make sure to open the hood and understand how the engine ticks!

The original article where Alistair Cockburn describes Hexagonal architecture is the best intro and a good read, no matter what year it is.

This topic came up today when we discussed the #crewmeister API, and made me think. Until I remembered that we once in a project used to use the pure POST params, which are basically key-value pairs. And the question also reminded me of my PHP times, there the server-side knew how to handle a key which looks like user[0] and builds and array. But when I ran into that problem back then we used to use python and there we didn't have that.

There are seven kinds of coupling.

From The Clean Code Talks this is a very good one by Misko Hevery where he is talking us out of using IFs, or at least trying to explain what IFs actually mean in code. And how we can better cater for those cases using polymorphism and how this also enables us to test better.

Unfortunately I missed Franziska's session at SoCraTes 2015 on this topic, but fortunately she wrote about it, make sure to also read through her commits backwards, of course :). Very nice and readable! An article "Kickstart your next project with a Walking Skeleton" she referred to, that explains the process too. While reading more and more of the [c2 wiki] I am asking myself where is the difference to a spike which Kent Beck defined as

Linked in the comments of this I found another great article, which I just have to quote.

I was about to write a "Handler" class. But I remembered that the "er" classes are not so good.
