This document summarizes a presentation about adopting Lean UX practices. It discusses moving from a traditional waterfall development process to an Agile approach, with an emphasis on continuous collaboration between designers and developers. Key aspects of Lean UX covered include using proto-personas and story mapping to validate user needs, wireframing and style guides to externalize work, and specification by example through acceptance criteria and documentation. The presentation argues for focusing on outcomes rather than outputs and adapting processes based on context rather than rigid adoption.

Martin Förtsch, Thomas Endres - Stereoscopic Style Transfer AI - Codemotion A...Codemotion
What if Virtual Reality glasses could transform your environment into a three-dimensional work of art in realtime in the style of a painting from Van Gogh? One of the many interesting developments in the field of Deep Learning is the so called "Style Transfer". It describes a possibility to create a patchwork (or pastiche) from two images. While one of these images defines the the artistic style of the result picture, the other one is used for extracting the image content. A team from TNG Technology Consulting managed to build an AI showcase using OpenCV and Tensorflow to realize such goggles.

Lars Wolff - Performance Testing for DevOps in the Cloud - Codemotion Amsterd...Codemotion
Performance tests are not only an important instrument for understanding a system and its runtime environment. It is also essential in order to check stability and scalability – non-functional requirements that might be decisive for success. But won't my cloud hosting service scale for me as long as I can afford it? Yes, but… It only operates and scales resources. It won't automatically make your system fast, stable and scalable. This talk shows how such and comparable questions can be clarified with performance tests and how DevOps teams benefit from regular test practise.

Don Goodman-Wilson - Chinese food, motor scooters, and open source developmen...Codemotion
Chinese food exploded across America in the early 20th century, rapidly adapting to local tastes while also spreading like wildfire. How was it able to spread so fast? The GY6 is a family of scooter engines that has achieved near total ubiquity in Europe. It is reliable and cheap to manufacture, and it's made in factories across China. How are these factories able to remain afloat? Chinese-American food and the GY6 are both riveting studies in product-market fit, and both are the product of a distributed open source-like development model. What lessons can we learn for open source software?

Dave Farley - Taking Back “Software Engineering” - Codemotion Amsterdam 2019Codemotion
Would you fly in a plane designed by a craftsman or would you prefer your aircraft to be designed by engineers? We are learning that science and empiricism works in software development, maybe now is the time to redefine what “Software Engineering” really means. Software isn't bridge-building, it is not car or aircraft development either, but then neither is Chemical Engineering. Engineering is different in different disciplines. Maybe it is time for us to begin thinking about retrieving the term "Software Engineering" maybe it is time to define what our "Engineering" discipline should be.
