Cross-platform Mobile Development

Xamarin

Presentation (Dutch): https://www.youtube.com/watch?v=J7GHFf3M9Ow With the release of Xamarin 3.0, a new way has been created to develop the UI for mobile applications. This library, named Xamarin.Forms, is the next generation of abstraction and makes it possible for developers to create cross-platform applications with 99,9% code re-use. Using Xamarin.Forms, you'll be able to use C# or XAML to define the mobile UI using one single way. Xamarin deliveres a load of standard controls, but makes it possible to create custom controls for a specific platform with ease. This way, you can create full native controls, and get the best performance and user experience out of your app. We'll dive into some basics of Xamarin.Forms, and check the power of the library as well as some bumps you might run into.

Android L and So Much More Webinar Slides

Xamarin

The Android L Developer Preview introduced a plethora of new APIs for developers to take advantage of, including Material Design, notifications, and new animations, to name a few. Xamarin developers can access these new APIs right now with our recently announced preliminary support in Xamarin.Android. With Google expected to release Android L fully this fall, it will be increasingly important to take advantage of these new APIs and get your app up-to-date. In the slides from our Android L and So Much More webinar on Tuesday, September 16th, Developer Evangelist James Montemagno walks through the top new and updated APIs in the release. In addition to everything new in the Android L Developer Preview, he also covers everything new in the Google Play Services, Support Libraries, Android Wear, and Android TV SDKs.

Visual Studio Toolbox - Introduction To Xamarin.Forms

James Montemagno

Video: http://channel9.msdn.com/Shows/Visual-Studio-Toolbox/VS-Toolbox-Xamarin-Forms Robert welcomes James Montemagno, a developer evangelist at Xamarin, back on the show for another series on building cross-platform apps with Xamarin and C#. In this episode, part one of four, we take a look at Xamarin.Forms, a cross-platform UI toolkit that sits on top of Xamarin.iOS, Xamarin.Android, and Windows Phone. We will see how to share not only the business logic of an application, but also how to build a fully native cross-platform UI completely in XAML, including features such as data binding, styles, and triggers.

C# everywhere: Xamarin and cross platform development

Gill Cleeren

C# is hotter than ever. Using Xamarin, we can use C# to not only build our apps on Windows Phone but also on iOS and Android. The magic that sits between are PCLs (Portable Class Libraries) that we can re-use on all these platforms. The goal is of course achieving the highest level of code sharing and re-using. In this talk, we'll see how we can share code between Windows Phone, iOS and Android to build a cross-platform app using Xamarin. You'll also see how much of the marketing fluff is real: do we really get a lower time-to-market when sharing code and is this approach really cheaper than building 3 apps separately? Come to this talk and learn all about it

Accelerate Mobile Success with a Mobile Center of Excellence

Xamarin

From streamlining employee activities to providing customers access to your business anywhere and any time, mobile is a crucial driver in transforming the enterprise. A successful mobile program is critical in order to innovate in your business and remain competitive for your customers, but going mobile presents numerous challenges to the enterprise that can force long delivery cycles and costly projects. An incomplete mobile strategy that is executed without proper governance and delivery framework will impair your mobile programs. What does it take to be successful with your mobile strategy? How can you navigate the multiple stages involved in creating a mobile app? How do you apply best practices and reduce maintenance costs on apps? And, lastly, how do you scale your mobile initiatives to dozens or potentially hundreds of apps across your enterprise? A Mobile Center of Excellence (MCoE) is the key to implementing your mobile strategy and setting up a scalable solution. * How a MCoE enables you to accelerate and scale in a manageable way * The five stages of the Mobile App Lifecycle: Design, Build, Test, Monitor, Maintain * The key elements to keep in mind when setting up a MCoE, including standards and governance * Insights on MCoE’s role with respect to Security, Integration, DevOps, Testing and Partnering

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

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). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

PHP Frameworks: I want to break free (IPC Berlin 2024)

Ralf Eggert

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.
