The document discusses making progressive web apps reliable. It recommends using service workers to cache assets and responses so the app works offline. Service workers allow precaching assets during install and returning cached responses to fetch requests. If the response isn't cached, the request can fallback to the network. When new updates are available, the service worker will update in the background. Other service worker events like sync allow background updating. Reliable progressive web apps provide instant loading offline through effective caching with service workers.

Progressive Web Apps aim to bring the benefits of native mobile apps to the web. They use newer web capabilities like app manifests and service workers to deliver app-like experiences through the browser. App manifests allow web apps to be installed on home screens and launched full screen like native apps. Service workers enable features like offline access and push notifications. Early adopters are seeing increased user engagement through Progressive Web Apps, with metrics like conversions and time spent improving. While browser support is still evolving, Progressive Web Apps provide a promising approach for delivering high-quality mobile experiences through the web.

SpringOne Platform 2017 Matthew McNeeney, Pivotal; Sam Gunaratne, Pivotal "The Open Service Broker API, a collaboration between Google, Red Hat, IBM, Pivotal and more, allows developers to deliver their services to applications running on multiple platforms across multiple clouds. After providing an introduction to cloud-native applications and the need for stateful services, we will explain how the Open Service Broker API project can help Spring developers build a variety of services that can be deployed once and consumed anywhere. We will then run a live demo where we build and deploy a service broker in Spring and consume it in via the Cloud Foundry marketplace."

The document is a slide presentation about AMP (Accelerated Mobile Pages) that discusses: - Mobile web challenges like slow devices and networks where JavaScript does heavy lifting. - How AMP addresses these with techniques like inlined CSS, prioritized resource loading, and async JavaScript to make pages load instantly. - Examples of companies that use AMP and the types of content it works for. - How AMP can be used as an entry point or data source to build progressive web apps with features like service workers for offline use.

Modern day web applications live and operate in a complex eco-system (Browser, Network/wifi, CDN, Cert Authorities, 3rd party sub resources and more). Securing the web server and web application business logic is not sufficient. The eco-system outside your direct control also contribute to the security risk posed to users of web applications. Security weaknesses and compromised elements in the eco-system would make , otherwise secure, applications risky for the users. We need to think of protecting your users in this un-trusted environment. The presentation describes such risks and options available to deal with them. NOTE: The same talk was presented in Armsec2016 conference (http://armsec.org/) and in OWASP Pune chapter meetup (29th Sep, 2016)

Caridy Patiño presented on the challenges of building mobile HTML5 applications. Some key challenges include browser fragmentation across devices, network failures, and the need to optimize applications for different runtime environments and adapt them for varying screen sizes and features. Patiño advocated writing applications using a single language, JavaScript, and customizing output per runtime and context while adapting the UI per form factor and feature detection. The goal is to build flexible applications that can run on multiple platforms.

HTTP/2 has been out for about a year. Over that time, Michael Gooding and Javier Garza have worked with many customers to implement it. However, beyond a turnkey solution that offers instant performance gains, HTTP/2 has led to a large amount of questions and confusion about how to optimize for it. Michael and Javier share their experiences with HTTP/2 over the last year, discussing case studies that demonstrate how performance can be improved over HTTP/2 while addressing backward compatibility, exploring using RUM data to review performance-related observations of customers after switching to HTTP/2, and offering hands-on demos of HTTP/2 with server push and HTTP/2 + QUIC. Topics include: Rendering impact without prioritization: Many solutions currently do not support server push or prioritization, which can have a negative impact on rendering when all resources instantly compete for the same bandwidth. Michael and Javier discuss solutions to mitigate this problem. Breaking out to smaller files: Best practices used to dictate combining CSS and JavaScript into as few resources as possible. In an HTTP/2 world, the advice is to leave files alone and serve them as they are. Michael and Javier look at examples where trade-offs exist between the delivery, management, compression, and caching and advise how best to approach the problem. Sprites: As with smaller files, what should we do with sprites in an HTTP/2 world? Looking at examples, Michael and Javier analyze the trade-offs in breaking a sprite out to smaller parts, looking at the effects of less-complex CSS against network performance to see how much of a difference it actually makes on performance. Delivering for HTTP/1.x: Many websites today still have a large user base from older browsers that do not and will not support HTTP/2. By reviewing case study sites optimized for HTTP/2, Michael and Javier display the delta between a site delivered over an HTTP/2 connection and an HTTP/1.x connection. Taking these differences into account, they then explore some common trade-offs and review the delivery options to provide good performance for both protocols at the same time. Real-life HTTP/2 web performance data: Michael and Javier explain how to use RUM data to review web performance data from large websites after enabling HTTP/2 and see the conditions where the performance improvements are at their best. Hands-on demo comparing the web performance of HTTP/2 versus HTTP/1.x 1 and HTTP/2 with server push and QUIC.

Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states. In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing. Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.
