PHP and its community has evolved really fast in the last few years to allow for professional architectures and solutions. However, there are thousands of existing PHP applications which have not evolved in the meantime and are now crippled and unmaintainable because of that. These applications represent a real threat to the competitiveness of the business that relies on them. The best approach in terms of business to solve this problem is progressive rewrite. Symfony2 and its modular architecture make it possible. This talk covers the main technical difficulties of the progressive approach when rewriting legacy PHP applications, and the corresponding solutions, some of which rely on the modularity of Symfony2.

Do you already know what big ball of mud means? And code smell?, Is your nose prepared to detect them? Can you affirm that you are commited with the mantainability? Do you have architectural sensibility to avoid these kind of situations? Or you are comfortable with the inertia of the day-to-day task of patching the holes. (it doesn't matter if it works..) While much attention has been focused on high-level software architectural patterns, what is, in effect, the de-facto standard software architecture is seldom discussed. This talk is intended to identify and summarize the causes that lead to misusing our time on complex maintenance, and give tips and best practices to avoid the big ball of mud and to achieve the best quality products.

Plastic SCM is a distributed version control system engineered for companies who require extensive branching and merging, distributed (multi-site/global) scenarios, and/or high performance. Plastic SCM is unique because it provides support for fully distributed and/or centralized repositories, a full graphical multiplatform user interface, a superior branching and merging technology, and provides security and management tools. Our Semantic Merge technology is the world’s first language-aware merge tool that fully supports C#, VB.NET, and Java, with additional languages soon to be supported. This tool facilitates complex refactoring while coders continue to work on their code. Contact us at sales@codicesoftware.com

Web Experience Factory (WEF) has matured as a framework and web and mobile solution development tool over the last several years. While the WEF design interface and services enable rapid custom development, too often implementation emphasis has focused more on speed versus how it fits into proper architecture.(The tendency is just start coding)! By its nature WEF allows for many levels of integration, but it still has to be structured in a way that fits proper design. This session is geared towards IT architects and developers and provides guidance to leverage WEF as a part of their overall architectural plan. We will discuss how WEF fits in various combinations of architecture. The goal will be to refer to best practices patterns, identify where WEF “fits” in your plan and to give you a head start on a successful use of WEF in your multichannel solutions. Topics covered will include WEF in Architectural patterns A sample Navigation Pattern in the View Some Patterns for WEF page automation and profiling Starting and governing a WEF project including QA Integrating your unique developer skills with WEF

As it was given at WeAreDevelopers World Congress, May 2018 in Vienna Austria # Get into Open Source! How to start or do more in the OSS community In this talk, we will go over the many ways in which you---YES YOU!---can get involved with open source. Whether you are highly technical or not technical at all, there are many ways to contribute to the open source community through: code contributions, issue triage, project management, communications, community relations, design, writing, testing, documentation, integrations, and more!. The more people involved the better, so let's destroy all barriers to entry, establish some on-ramps and hit the road! This talk is not just cheerleading. We will go over real examples and real entry points for becoming a valuable contributor to the open source community.

Fuse Tooling is a powerful Integrated Development Environment for integrations projects based on Apache Camel and Jboss Fuse. During the talk, I will show the best features of Fuse Tooling which had a reworked UI this year: how to graphically defines Camel routes how to graphically debug your Camel routes how to leverage the IDE with OpenShift as target platform Apache Camel is an integration framework based on Enterprise Integration Patterns. It empowers developers to define routing and mediation rules. JBoss Fuse is the productized version of Apache Camel provided by Red Hat. It helps you to configure and deploy in tested and supported environments. Environments that can be on-premise or in the Cloud.

How to contribute to Eclipse

Aurélien Pupier

After one year of regular work on our build mechanism and Continuous Integration infrastructure, we are able to provide RCP products, along with their complete test suite, more than 3 times faster than before. And guess what, we are using less physical resources. The path to this result was quite long and sometimes tedious, but we finally managed it. I will share our experience and provide tips so you can speed up your own build. I will also mention which improvements are coming. I will explain the methods used to identify bottlenecks and which technical solutions we applied (and the ones we dropped). This talk will go through the usage and possibilities brought by Tycho, Target Platforms, Hudson/Jenkins with some of its plugins and a Maven Repository Manager.

During this presentation, I will demonstrate how to generate an automatic custom memory report integrated in a Continuous Integration. It detects memory leaks very early in development process and provides a preliminary report. The Bonitasoft team implemented such a solution with the Hudson continuous integration server and the Memory Analyzer Tool (MAT) on our Eclipse RCP application. This talk will be an opportunity to share our experience and present the steps to achieved the goal: Take a Heap Dump programmatically at the end of Test execution Create a custom MAT report or use the ones provided Launch MAT reports analysis on the Heap Dump Integrate reports analysis in the Hudson/Jenkins job

Ever caught yourself nodding along when someone mentions "delivering value" in Agile, but secretly wondering what the heck they actually mean? You're not alone! Join us for an eye-opening session where we'll strip away the buzzwords and dive into the heart of Agile—value delivery. But what is "value"? Is it a mythical unicorn in the world of software development, or is there more to this overused term? This isn't going to be a sit-and-get lecture. We're talking about a face-to-face, interactive meetup where YOU play a crucial role. Come along to: Define It: What does "value" really mean? We’ll build a definition that’s not just words, but a compass for your Agile journey. Contextualise It: Discover what value means specifically to you, your team, your company, and your industry. Because one size does not fit all. Deliver It: Share strategies and gather new ones for uncovering and delivering true value—no more shooting in the dark!

ScyllaDB has the potential to deliver impressive performance and scalability. The better you understand how it works, the more you can squeeze out of it. But before you squeeze, make sure you know what to monitor! Watch our experienced Postgres developer work through monitoring and performance strategies that help him understand what mistakes he’s made moving to NoSQL. And learn with him as our database performance expert offers friendly guidance on how to use monitoring and performance tuning to get his sample Rust application on the right track. This webinar focuses on using monitoring and performance tuning to discover and correct mistakes that commonly occur when developers move from SQL to NoSQL. For example: - Common issues getting up and running with the monitoring stack - Using the CQL optimizations dashboard - Common issues causing high latency in a node - Common issues causing replica imbalance - What a healthy system looks like in terms of memory - Key metrics to keep an eye on This isn’t “Death-by-Powerpoint.” We’ll walk through problems encountered while migrating a real application from Postgres to ScyllaDB – and try to fix them live as well.
