  • Experiences from Getting Started as a Lead

    Having a transition period to lead teams together with a mentor helped Dan Persa to have a smooth switch from senior software engineer to engineering lead. At Codemotion Amsterdam 2019 he shared some of his experiences and learnings, in order to inspire other developers to take the leadership path.

  • Mature Microservices and How to Operate Them: QCon London Q&A

    Microservices is an architectural approach to keep systems decoupled for releasing many changes a day, said Sarah Wells in her keynote at QCon London 2019. To build resilient and maintainable systems you need things like load balancing across healthy nodes, backoff and retry, and persistence or fanning out of requests via queues. The best way to know whether your system is resilient is to test it.

  • Reconciling Kubernetes and PCI DSS for a Modern and Compliant Payment System

    Ana Calin, systems engineer at Paybase, gave an experience report at QCon London [slides PDF] on how the end-to-end payments service provider solution managed to achieve PCI DSS level 1 compliance (the highest) with 50+ Node.js microservices running on Google Cloud Kubernetes Engine (GKE), and using Terraform for infrastructure provisioning and Helm for service deployment.

  • Lynne Cazaly on Making Sense Using Hand-Drawn Images

    At the recent Agile on the Beach New Zealand conference, author and graphic facilitator Lynne Cazalay presented a masterclass on sensemaking; some techniques to clarify ideas through graphical images - simple diagrams which can help identify the important elements of any narrative and represent them in a style that makes content meaningful.

  • Sitting Considered Deadly: Introduce Movement in Our Workdays

    Prolonged sitting wreaks havoc on our bodies and our minds. A first step to introduce more movement throughout your workday is to organize a sit-stand workstation, claimed Marek Stój in his talk Sitting Considered Deadly at Codemotion Amsterdam 2019. He suggested alternating between the two and trying out various ways in which one can sit or stand.

  • Build a Monolith before Going for Microservices: Jan de Vries at MicroXchg Berlin

    Most developers don’t work at global large-scale companies like Netflix. Most developers work in much smaller companies with maybe up to 50 – 80 developers, Jan de Vries noted in his presentation at MicroXchg Berlin, where he argued that a properly built monolith in many cases is superior to a microservices based architecture. With a well-built monolith, it will also be easy to pull services out.

  • Reflecting on Top-Down or Bottom-Up System Design: Vaughn Vernon at MicroXchg Berlin

    Should software design be driven by a top-down or bottom-up approach? Vaughn Vernon asked the question in his presentation at MicroXchg Berlin, where he discussed different approaches to software design, actor model, reactive domain-driven design and the importance of an emergent architecture.

  • Samsung's Agile & Lean UX Journey

    Samsung has applied a team-led agile transformation followed by a culture-led agile transformation, to focus teams on real users and valuable products. Teams create and use personas which they use to do team-driven user research throughout product development, said Jaesung Jo, senior UX designer at Samsung SDS, in his talk at the Lean and Agile ME Summit 2019.

  • Creating Events from Databases Using Change Data Capture: Gunnar Morling at MicroXchg Berlin

    When you store data in a database, you often also want to put the same data in a cache and a search engine. The challenge is how to keep all data in sync without distributed transactions and dual writes. One way is to use a change data capture (CDC) tool that captures all changes made. In a presentation at MicroXchg Berlin, Gunnar Morling described Debezium, an implementation of CDC using Kafka.

  • Migrating a Retail Monolith to Microservices: Sebastian Gauder at MicroXchg Berlin

    In his presentation at MicroXchg in Berlin, Sebastian Gauder described how he and his teams migrated an existing food retail monolith at REWE, a large German company, into several business domains with 270 microservices, while increasing the number of teams from two up to 48. He also discussed the different design goals and rules they setup to make this possible.

  • Discovering Culture through Artifacts: QCon London Q&A

    Behavior and values are two critical components to organizational culture; values denote what the organization believes in, and behaviors are rooted in those values, argued Mike McGarr, engineering leader at Slack. At QCon London 2019 he spoke about improving your understanding of an organization’s culture, the key components of culture, and what to look for in order to learn about the culture.

  • Building High-Quality Products with Distributed Teams

    To ensure the quality of the products and services, Intermedia uses a common test & pre-production environment for all distributed teams. Lilia Gorbachik, product manager at Intermedia, mentioned at European Women in Tech that having a mature testing process, working with risks, and making daily decisions from a high-quality product perspective are key aspects to build high-quality products.

  • Mashreq Bank’s Lean Agile Journey

    After having seen and evidenced the tangible benefit of lean at Mashreq Bank, agile was seen as a natural progression, an evolutionary step. Agile and lean are well-linked; you still need to identify waste, and remove non-value add activities so you can spend more time doing what the customer needs, argued Steve Snowdon. Together with Ed Capaldi he spoke about Mashreq Bank’s Lean Agile Journey.

  • QCon New York 2019 (June 24-28) Tracks Announced & Registrations off to a Fast Start

    The 8th annual QCon New York returns to the Marriott Marquis June 24-26, 2019. QCon, organized by the people behind InfoQ.com, is dedicated to providing a platform for innovators and early adopters to tell their story in hotbeds of software development like Beijing, London, San Francisco, Sao Paulo, Shanghai, and New York.

  • Agile in Higher Education: Experiences from The Open University

    Universities need to embrace an agile and product mindset, as they are grappling with hypothesis-driven development of new kinds of products and services of which they understand very little, for users whose behaviours and needs they little understand, said Matthew Moran. He presented applying the agile mindset, principles and practices for online course development at Aginext 2019.
