  • ContainerAware Considered Harmful

    by Tobias Schlitt on Mon, 07 Oct 2013 11:25:46 +0200

    A while ago I tweeted

    ContainerAware is the new Singleton.
    While many people agreed by retweeting and faving. I feel the need to elaborate some more on this statement and safe the explaination for the future.

  • Fixing Legacy Code

    by Kore Nordmann on Mon, 09 Sep 2013 07:07:03 +0200

    Working on a green-field project where you can start from scratch and avoid all the annoyances you experienced in earlier projects is fun. However, most developers cannot enjoy this pleasure but work with legacy code 99% of their time. Even harder, many green-field projects turn into legacy within months or even weeks.

  • Finding the right Test-Mix

    by Benjamin Eberlei on Mon, 19 Aug 2013 10:50:38 +0200

    The topic of Test Driven Development (TDD) and unit-testing usually creates heated discussions among developers. We at Qafoo are not an exception and the topic how to apply TDD in our daily work regularly leads to heated discussions. One reason for this is that both TDD and unit-testing combined are by some people seen dogmatically as the only way to do software development.

  • Testing: Find the Sweet Spot

    by Kore Nordmann on Wed, 17 Jul 2013 08:07:58 +0200

    How we need to craft architecture and design in order to significantly reduce the cost for tests. How to escape from the trap of the inner-platform antipattern, where we need to provide all infrastructure and business models with an ugly, mocked twin. Simply: How to efficiently write tests? And how to avoid that everyone hates them within 10 months, so that they would rather deactivate them instead of fixing them.

  • Ducks Do Not Type

    by Kore Nordmann on Thu, 11 Jul 2013 14:51:23 +0200

    I consider public methods not originating from an abstract class or interface a code smell – at least when following class based object orientation design principles. Let me explain why…

  • A tricky Thing: The arguments-object

    by Jakob Westhoff on Mon, 01 Jul 2013 08:10:13 +0200

    Incited by a tweet regarding JavaScripts arguments-object, I decided to detail this object in this blog post. A lot of people are somewhat confused about the inner workings of JavaScript engines in general. Every now and then most JavaScript developers can't explain why certain things happen and others don't. One of those mysteries fueling the confusion is the arguments-object. This post will help to solve this mystery once and for all.

  • Embedding REST Entities

    by Tobias Schlitt on Thu, 13 Jun 2013 10:35:27 +0200

    During my talk at IPC Spring I showed an approach for embedding entities in REST responses. This methodology might be useful if the standard use-case for your API is to request multiple related entities together. The downside of such an approach is the raised complexity of caching and especially purging logic. In this blog post I will further elaborate on the approach of resource embedding.

  • Dependency Management / Mocks, Stubs and Spies with JavaScript

    by Kore Nordmann on Fri, 16 Sep 2016 11:44:49 +0200

    At this years IPC Spring I gave two sessions about different JavaScript-Topics. Eventhough most of us are PHP-Developers at their heart, in todays world JavaScript has become an integral component of most webapplications. That's why I give a lot of trainings about JavaScript these days. Take your chance to peek at the two sessions I just presented.

  • Pragmatic REST & BDD at IPC

    by Tobias Schlitt on Wed, 05 Jun 2013 18:59:13 +0200

    On the train back I'm just uploading the slides of my talks at the International PHP Conference in Berlin, which ended some minutes ago. In my first talk I captured my experience with designing RESTful web services, summarizing pitfalls and low hanging fruits under the topic "Pragmatic REST". The second talk dealt with Behavior Driven Development on basis of Behat. Find the slides for download here.

  • Slides: Behat & Beautiful APIs

    by Kore Nordmann on Thu, 16 May 2013 08:14:14 +0200

    Last Wednesday I did a little talk marathon by first presenting a Webinar on Behavior Driven Development with Behat and afterwards going straight to Cologne for the Symfony Usergroup, where I spoke about Designing Beautiful APIs. Find the slides of my talks here.
