Jetty 9 is not only a great production server but provides features such as the Jetty Maven plug-in and embedded Jetty that help you in application development and integration testing. This session covers Jetty 9ās scalability, stability, performance, and features such as the new HTTP client and how to configure Jetty for optimal production performance.
HTTP 1.1, which is the backbone of pretty much everything weāve been using on the Internet, has been around for over 15 years. Recently the HTTP 2.0 specification has been completed and gradually application servers will start supporting it. It does make one wonder though: why change if something has been working for so long. In this talk weāll examine the shortcomings of HTTP 1.1 and how 2.0 intends to address those. Weāll see what we need to know and how itās going to affect our existing applications, and future ones.

JUDCon 2013 Presentation by Mark Addy, C2B2 Senior Consultant- JBoss Data Grid and WebSockets: Delivering Real Time Push at Scale
The real time web is coming with WebSockets in HTML 5. The big question is how to deliver event driven architectures for WebSockets at scale. This session delivered by the experienced middleware consultant provides an insight on how combining JBoss Data Grid with WebSockets can deliver enterprise scale push to web devices. The session first provides an introduction to WebSockets and delves into typical JBoss Data Grid architectures and how they deliver linear scalability and high availability. We then look at the event capabilities inherent in JBoss Data Grid that when hooked up to a WebSockets server can deliver data grid updates in real time to HTML 5 mobile devices.

Art and Science of Web Sites Performance: A Front-end ApproachJiang Zhu
Ā
People love fast web sites, but up until now developers have been focusing on the wrong area. Network (TCP, buffers, routing) performance and Backend (web server, database, etc.) performance are important for reducing hardware costs and improving efficiency, but for most pages 80% of the load time is spent on the frontend (HTML, CSS, JavaScript, images, iframes, and others). We will talk about the best practices for making web pages faster, provide case study from top web site, and introduce the tools we use for researching performance. In addition to know how to improve web performance, we will also try to gain an understanding of the fundamentals of how the Internet works including DNS, HTTP, and browsers. This talks was given as an Educational Series called Fog Computing Reading Group at Cisco Advanced Architecture and Research. The content is derived from the materials by Steven Sounders (Google/Stanford), Collin Jackson (Stanford/CMU) and Daniel Austin (eBay).

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
Ā
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
Ā
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more āmechanicalā approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Ā
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navyās DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATOās (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
