Progressive Web Apps: o melhor da Web appficada

The document discusses techniques for improving frontend web performance, including splitting codepayloads, loading scripts without blocking, and not scattering scripts across pages. It recommends focusing first on optimizing frontend performance since 80-90% of end user response time is spent loading frontend resources. Specific techniques include splitting JavaScript payloads into above-the-fold and below-the-fold code, using techniques like XHR and iframes to load scripts asynchronously without blocking page rendering, and avoiding placing inline scripts between stylesheets and other page resources.

The document discusses techniques for loading JavaScript files to optimize website performance. It describes methods like splitting the initial payload, loading scripts asynchronously without blocking parsing and rendering, and deferring non-critical scripts. Examples of major sites like Gmail, Facebook, Google and Wikipedia that use these techniques are also provided.

The document discusses techniques for improving frontend web performance, with a focus on optimizing JavaScript loading.

The document discusses techniques for improving frontend web performance, including splitting code into critical and non-critical sections, loading scripts asynchronously without blocking other downloads, and avoiding scattering scripts throughout a page. It provides examples of sites that could benefit from these techniques and recommends tools like YSlow for auditing performance. The overall message is that frontend optimizations like JavaScript improvements can significantly speed up sites.

This document discusses strategies for improving JavaScript performance on websites. It begins by noting that JavaScript is often the number one cause of slow web pages. It then reviews the history of JavaScript loading approaches, from loading scripts in the page head in 1995 to more modern async and deferred loading. It discusses using localStorage as a cache and the Google Analytics async snippet as examples. It concludes by recommending tools and resources for measuring and improving JavaScript performance, including WebPagetest.org, ControlJS, and Steve Souders' own site and books.

HTML5 is the latest version of HTML that introduced new elements such as <video>, <audio>, <canvas> and new form input types. It allows embedding multimedia directly in web pages through elements like <video> and <audio> and drawing graphics on the fly using <canvas>. New input types like email, number, range etc provide better user experience for entering different data types.

The document discusses web frameworks and how they provide libraries and structure for common tasks in web application development to promote best practices and allow developers to focus on their specific application needs rather than solving common problems.

This document discusses responsive web design techniques including: - Using viewports and media queries to adapt layouts for different screen sizes. - Sizing images fluidly using max-width: 100% so they are responsive. - Design patterns for responsive tables, hiding/showing content, and converting menus to dropdowns. - Tools like Modernizr, Respond.js, and frameworks like LESS to support responsive design goals. - Tips like using relative units (ems/percentages) over fixed pixels and transitions for visual changes.

This document introduces progressive web apps (PWAs), covering their origins, advantages over mobile apps, implementation basics, and key elements for conception and development. It discusses how PWAs make the best of both web and app concepts by being instantly accessible like web pages but also engaging users through features like push notifications. The document provides code samples for implementing service workers, manifest files, and other PWA features and recommends tools and references for building PWAs.

Progressive Web Apps (PWAs) are websites that utilize modern web features to deliver native app-like experiences to users. The minimum requirements for a PWA are that it is served over HTTPS, includes a web app manifest, and registers a service worker. Service workers allow PWAs to work offline by handling fetch events and caching assets. While adding a PWA to a user's home screen can improve engagement, the true battleground is changing user perception of the capabilities of web apps versus native apps.

One of the main advantages of web applications is their ease of deployment. The same can't be said about desktop applications. However, desktop applications work without a network connection. While this used to be a deal breaker for web applications, recent developments in HTML 5 and browser plugins such as Flash and Silverlight allow developers to create web applications that work both online and offline. In this session, Matt will demonstrate how to create offline web applications in HTML 5, Silverlight and Air. Also, other factors for offline applications, such as client-side data storage, will be examined in detail.

Palestra sobre imagens responsivas dadas no Encontro Locaweb 2015 pelo Sérgio Lopes

O documento descreve as principais diferenças entre HTTP 1.1 e HTTP 2.0. HTTP 2.0 introduz binário, multiplexação e compressão que otimizam o desempenho reduzindo tráfego de rede e latência da conexão. HTTP 2.0 permite várias requisições em paralelo em uma única conexão TCP.

"Essa história vai melhorar as vendas. Essa refatoração vai melhorar a manutenção". Será? Se queremos escolher histórias e manter um produto melhor para o cliente final, essa decisão deve ser baseada em alguma medida. Complexidade do código? Coesão? Aguentar altas cargas? Diminuir taxas de erro? Efetuar mais compras? Para entender qualquer uma delas é preciso medir: veremos nessa palestra como pegar um projeto cujo build mínimo está automatizado, mediremos a complexidade do código, o desempenho em relação a erros, a vendas e a percepção do usuário final. Mantemos um rastreamento dessas métricas com o passar do tempo: encontrando os commits responsáveis pela quebra nas regras estabelecidas. A decisão se algo é bom ou não deixa de ser romântico e passa a ser algo lógico.

The document discusses HTTP 2.0 and SPDY. Some key points include: 1. HTTP 2.0 uses a binary format instead of text and allows multiplexing requests over a single TCP connection to reduce latency. 2. Features like header compression, server push and request prioritization help optimize loading of web pages. 3. SPDY is an experimental protocol developed by Google that implements many of the same optimizations as HTTP 2.0.

Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data. The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs. Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution! Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.

Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality. Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality. Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality. Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank? ** Episode Overview ** In this first episode of our quality series, Kristen Hansen and the panel discuss: ⦿ What do we mean when we say patent quality? ⦿ Why is patent quality important? ⦿ How to balance quality and budget ⦿ The importance of searching, continuations, and draftsperson domain expertise ⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications https://www.aurorapatents.com/patently-strategic-podcast.html

Kief Morris rethinks the infrastructure code delivery lifecycle, advocating for a shift towards composable infrastructure systems. We should shift to designing around deployable components rather than code modules, use more useful levels of abstraction, and drive design and deployment from applications rather than bottom-up, monolithic architecture and delivery.
