Design and Implementation of a DDD-Based Modular Monolith
Kamil Grzybek recently published a project where he has designed, implemented, and in detail described a monolithic application with a Domain-Driven Design (DDD) approach. His goal is to show how a monolithic application can be designed and implemented in a modular way. He also discusses some architectural considerations and design patterns he has found useful in the application.

Eric Evans Wants to Improve the Language of DDD
Eric Evans wants architects to actively engage in improving the language used when modeling and designing complex systems. Some of the fundamental terms used in DDD, such as Bounded Contexts, are often misunderstood. Evans wants to see an active community try to address these concerns, with the goal that DDD "should be a real, living body of thought."

Optimized Lazy Image Loading with Progressive JPEG and HTTP Range Requests
Christoph Erdmann recently detailed an interesting technique for image lazy loading using Progressive JPEG and HTTP range requests. Unlike other image placeholder and lazy loading techniques, using range requests do not result in downloading extra image data while still providing a small preview image similar to the original.

UX Design Ethics: Dealing with Dark Patterns and Designer Bias
It’s easy to design an interface that persuades users into something that’s in the interest of a company. The question design community needs to ask more often is if we should comply with such practices, argued Agnieszka Urbańska and Ewelina Skłodowska, UX designers, at ACE! 2019. Dark patterns and even unconscious designer’s bias contradict empathy and are incompatible with human-centered design.

Pixi.js, HTML5 Alternative to Adobe Flash, Adds WebGL Support for Cross-Platform, Interactive Apps
PixiJS, a standard-based alternative to Adobe Flash, released its fifth major version with faster rendering and lower GPU utilization. PixiJS v5 abstracts WebGL features behind a new API which falls back to HTML5’s canvas if needed. Developers thus need not dive into the WebGL API or deal with device compatibility to create rich, interactive graphics, cross-platform applications, and games.

How Design Systems Support Team Communication and Collaboration
By using design systems, design teams can improve their workflow, reuse their knowledge, and ensure better consistency, said Stefan Ivanov. They allow one to fail faster and to speed up the iteration cycle, enable spending more time collecting user feedback in the early stages of product design, and reach the sweet spot of a product market fit much faster.

Human Centered Design for Special Needs: Q&A with Mileha Soneji
Observing users to understand their needs helps to define the problem you need to solve, argued Mileha Soneji. In her talk at ACE Conference 2019 she showed how human-centered design with minimum viable prototypes can help to gain better insight faster, and that breaking down problems into smaller problems can be used to ideate simpler solutions.

Design and Security in Agile: QCon London Q&A
Reviews of design diagrams by domain experts can detect potential security breaches not found by vulnerability scans or security automation. Such reviews should focus on critical functions like issuing and managing access tokens, transferring data to external services, and running untrusted code, said Kevin Gilpin, enterprise software engineer and co-founder of AppLand, at QCon London 2019.

Are Frameworks Good or Bad, or Both?
Preferring frameworks or libraries is somewhat controversial, Frans van Buul, Evangelist at AxonIQ, the company behind Axon Framework, writes in a recent blog post. Many argue in the favour of libraries but Van Buul thinks that a framework can be very valuable when building business applications. He believes this to be especially true for applications based on CQRS, DDD and event sourcing.
