Guidance on how to develop a progressive web app using react native!

Shelly Megan

Growth of mobile web traffic has been outpacing desktop web traffic for years, and data reveals that users are likely to abandon experiences that too long to load. Progressive web apps aim to be reliable, fast and engaging, regardless of form factor or quality of internet connection. We'll walk through several key aspects of PWAs, illustrating performance and usability improvements by showing quantitative comparisons to an equivalent "classic SPA".

These are the slides used in my #devone (www.devone.at) keynote presentation: DevOps is one of the most abused and overrated marketing terms in the last years! That’s not an alternative fact! It’s just Andi’s opinion! Yet - it is a very real thing that allowed many software companies to transform the way they think about software engineering. DevOps can mean something totally different thought depending on who you are and what type of business your company is doing. To clarify things, Andi gives us insights on how he explains the benefits to “DevOps Newbies” and how software companies around the world implement it in their own ways. Andi will answer: What does it really mean for developers, testers and operators? What will change? How does Facebook deploy twice a day without big issues? How does DevOps work in financial, government or healthcare where you have tight regulations? Does it mean Devs are responsible for Ops? Does it only work in the cloud? Or can we apply it to “old fashioned” on premise software as well? Learn for yourself and make up your own mind on whether DevOps is just a marketing term or something that can benefit you!

Becoming the next Uber is only possible when bringing your ideas faster to your end users. Some aspects of DevOps are perfect for that as it only works if Ops and Dev work closely together. But what does this mean for you as a developers? Delivering code faster with the high chance of failing faster? In my opinion we need to look at Key Technical Metrics such as Memory Usage per User or Request, # of SQLs, # of Service Calls, Transferred Bytes, ... - these are metrics you need to track starting at your workstation all the way through CI into Ops – and don’t forget the Business: How often is the new feature really used? What does it cost to run it? Let these metrics act as Quality Gateways and stop builds early before they Crash your System: faster than ever. In this session we look at how companies like Facebook, CreditOne and Co apply metric-driven DevOps. We look at use cases that crashed rapid deployments, identify metrics that identify the reason of the crash and learn how to use these metrics to steer your pipeline to build better code, deploy faster, without failing faster!

Slides used for https://www.devopsdays.org/events/2017-toronto/program/andreas-grabner/ In 2011 we delivered 2 major releases of our on premise enterprise software. Market, technology and customer requirements forced us to change that in order to remain competitive. Now – in 2017 - we are deploying and providing feature releases every 2 weeks for both our on premise and SaaS-based offering. We deploy 170 SaaS production changes per day and have a DevOps pipeline that allows us to deploy a code change within 1h if necessary. To increase quality, we built and provide a DevOps pipeline that currently executes 31000 Unit & Integration Tests per Hour as well as 60h UI Tests per Build. Our application teams are responsible end-to-end for their features and use production monitoring to validate their deployments which allows them to find 93% of bugs in production before it impacts our end users. In this session I explain how this transformation worked from both “Top Down” as well as “Bottom Up” in our organization. A key component was the 4 people strong DevOps Team who developed and “sell” their DevOps Pipeline to the globally distributed application teams. I will give insights into how our pipeline enables application teams to design, code, test and run a new feature for our user base. I will also talk about the “dark moments” as change is never without friction. Both internally as well as with our customers who also had to get used to more rapid changes.

React Native is often our first choice for mobile app technology. This framework is high-speed and allows for profound control over mobile projects. Mobile application usage has increased dramatically over the past few years. Many apps can do everything, from booking flights to getting a home manicure/pedicure, finding a partner, and even searching for a flight. The race is on for app developers who can deliver a classic User Interface (UI) and a fantastic User Experience (UX) for iOS and Android. They are looking for apps that can be used across all platforms to reach a larger audience and lower development costs.

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
