  • WebAssembly Used to Extend Life of Flash Legacy Content

    Adobe will stop distributing and updating Flash Player after December 31, 2020. The large amount of Flash content accumulated over the years is however not entirely lost. Ruffle, a Flash emulator, and CheerpX, an x86 virtualization technology, both leverage WebAssembly to play .swf files in the browser.

  • After MS-DOS, Microsoft Now Open Sources GW-Basic

    Microsoft released on GitHub the original 8088 assembly language sources for its interpreter for GW-BASIC 1.0, a dialect of the BASIC programming language released in 1983 and bundled with MS-DOS operating systems on IBM PC compatibles. After re-open-sourcing MS-DOS, Microsoft proceeds with releasing GW-BASIC under an MIT license due to numerous requests.

  • Decomposing a Monolith Does Not Require Microservices - Sam Newman at QCon London

    Sam Newman says the goal of decomposing a monolith must be independent deployability, and developers need to focus on the outcome, not the technology. Speaking at QCon London, he said, "The monolith is not the enemy" and, "Microservices should not be the default choice."

  • WebAssembly Used by Java-to-Web Compiler CheerpJ 2.0 to Port Java Applications to Browsers

    LeaningTech recently released the second major iteration of CheerpJ. CheerpJ 2.0 may convert Java applications into a mix of HTML, WebAssembly and JavaScript, so that developers can run Java applications (including applets) in browsers or integrate Java libraries into web applications. CheerpJ 2.0 uses WebAssembly to improve runtime speed.

  • 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."

  • Creating a Multi-Team Test Automation Solution

    A solid test framework with automated tests can increase the confidence to release. Cross-team pairing on the framework made it possible for a team to build quality in from the start; it also brought the teams together and upskilled the testers in test automation.

  • Michael Feathers Wants Error Elimination to Be a Design Driver

    Michael Feathers finds errors fascinating, but acknowledges that most developers don't spend a lot of time focusing on them. He also thinks most error handling is kind of giving up. Although best known for his books about working with legacy code, Feathers used his keynote presentation at Explore DDD 2018 to discuss how eliminating errors can be a design driver for software systems.

  • Why Software Developers Should Take Ethics into Consideration

    Most of the software that influences the behavior of human beings wasn’t created with strong ethical constructs around it. Software developers should ask themselves ethical questions like “who does this affect?”, “who could get hurt by this?”, and “who does this disadvantage or advantage?”, try to answer them, and be comfortable with questions they can’t answer yet.

  • Bridging the Gap between Legacy Systems and Modern Techniques

    Aging platforms that are managed with manual, time consuming processes can be costly. Teams can make a business case to management based on hours lost by repetitive work or re-work caused by human error for introducing modern techniques like automation tools and containers. The result is a predictable and repeatable process with minimal human interaction to deploy more often and more confidently.

  • Refocusing e-Commerce with Lean

    Auchan:Direct, the online grocery delivery service of Auchan France, decided to apply lean to develop a new e-Commerce website.

  • Continuous Delivery at Klaverblad Insurance

    Continuous delivery should be treated as an agile project as it is about automating your deployment. You have to speed up in small steps and gain trust by doing small deliveries and solve problems fast. The story about how Klaverblad insurance has implemented Agile, DevOps, continuous delivery, and microservices.

  • Understanding Large Codebases with Software Evolution

    InfoQ interviewed Adam Tornhill, author of Your Code as a Crime Scene, about software evolution and mining social information from code and how to use this to increase the understanding of large codebases, how to create a geographical profile of code, and the benefits that can be gained from techniques like mining social information and geographical profiling.

  • Technical Debt and Team Morale when Maintaining a Large System

    Thomas Bradford talked about his experience with maintaining a monolith Java based system with zero test coverage and large technical debt at the Agile Testing Days 2015. InfoQ interviewed him about the problems that they had maintaining the system and the technical debt that had been build up, why they decided to take a different approach and how they improved team morale.

  • Rebuild or Refactor?

    Should you rebuilding or refactoring software?An interview with Wouter Lagerweij about what it is that makes refactoring so difficult, if rebuilding software is less risky than refactoring, and how continuous delivery fits with rebuilding software.

  • Directing complex IT-landscapes with Agile

    Where many organizations use agile to develop IT products, agile principles and practices can also be applied for maintaining landscapes of commercial products. Gert Florijn and Eelco Rommes will talk about directing complex IT-landscapes in public sectors such as healthcare and local and national government organizations at the Agile and Software Architecture Symposium 2015.
