The learning coffee break is back! Today with a few tips I collected from others about preparing and giving conference talks:
To me, a good talk is one where I learn something new or come away with some change in perspective. The more I learn / the more the speaker makes me think differently about something, the better. So, to give a good talk, you need to say a new-to-your-audience thing in an understandable way.
I don’t mind too much how many times you say “um” or how nice your slides are.
This Tweet in 2015 blew my mind. I learned a bit about designing interactive systems and psychology in design, so I could relate immediately. It inspired me to a talk “Usability for Programmers” at WebCon Aachen, that unfortunately never went public because the event was cancelled, and I am yet waiting for a new chance to deliver it.
But I find the content too interesting to leave it hidden any longer, so here’s a blog post!
One of my goals for 2017 is to make TDD katas a part of my daily routine. What is a Kata? Just as in martial arts it is training through repetition, practicing the same exercise again and again until you can do it in your sleep.
Some would say, it is the only way to learn TDD. This makes sense for several reasons: you start in a small, protected scope and can apply pure test driven development. This way you are able to train the different mindset (the red-green-refactor cycle) without frustration. It means, you will not have to learn working around the quirks of a framework at the same time. Continue reading “TDD Kata 01 – The Bowling Game”
I’m proud to annouce that I will present the Nomad Mage session of January 2017. Nomad Mage is the Magento offspring of Nomad PHP and describes itself as:
Nomad Mage® is a virtual user group for Magento developers who understand that they need to keep learning to grow professionally. We meet online monthly to hear some of the best speakers in the community share what they’ve learned.
My topic: “Keep Magento Out of Your Magento Extensions – Refactoring to Framework Independent Code”
To port an existing Magento 1 extension to Magento 2, it can be helpful to first extract the business logic into a reusable library. This also makes for more testable and future-proof code. But how can it be done?
On Nomad Mage I’m going to walk through real examples to show you how such a refactoring can be approached. Although we will focus on refactoring existing Magento 1 extensions, the patterns you will learn are also useful for new extensions, Magento 1 or Magento 2.
Recently I had the opportunity to take a peek into the source code of Spryker, the e-commerce framework that’s composing itself to be the new player in the enterprise area. Spryker was originally developed by the Berlin based incubator Project A to be used in the companies that they build up and is supposed to be released to the public this year. While “public” is not enirely true, I can say so much in advance: An open source version is not planned, licenses will cost about 100.000 € / year. Agencies can register as partner, to get access to source code and documentation without a license. With the first sold license they get access to additional training material. Freelancers are not addressed. Already listed as partner are the agencies CommercePlus and Symmetrics that are well-known in the German Magento scene.
What is special about Spryker?
Spryker doesn’t consider itself as ready-to-use product but as framework that provides the building blocks for an individual e-commerce solution from which you can choose and extend for your project. This takes the reality into account that no project is equal to the next and each shop has its own processes and infrastructure, which you have to address individually.
The core of Spryker are two separate applications, Yves and Zed. In short, Yves is a lightweight application for the frontend, Zed the big gun for the backend.
Yves (in the first version developed with Yii, now with Silex) reads any needed data from an in-memory NoSQL backend such as Redis.
Zed (Zend Framework 2) handles communication with MySQL, message queue and external systems, and contains the business logic for order processes and so on.
