Several serverless patterns are then outlined, such as hosting a static website or REST API using AWS Lambda and API Gateway. Finally, the document demonstrates a serverless application and discusses future directions for serverless technologies.
Azkaban
Azkaban is a batch workflow job scheduler created by LinkedIn to run Hadoop jobs. It features a simple web UI, scheduling of workflows, tracking of user actions, and email alerts. While it has a small community and only time-based scheduling, it can run command-line processes making it a good alternative to cron. The architecture includes a solo server mode for investigation and a two server mode for production.
Serverless Systems: The Future is Here
This document is a presentation about serverless systems and architectures. It introduces serverless computing as a highly abstracted cloud computing model where infrastructure is fully managed by a third party. Key benefits of serverless include no server management, easy scalability, and pay-per-use pricing. The presentation demonstrates serverless concepts like AWS Lambda and event-driven architectures using examples and demos. It also discusses developing serverless applications locally and using frameworks like Spring with serverless.

Surati Tech Talks 2022 / Build reliable Svelte applications using Cypress
Tired of having users email you that your Svelte application is broken? Turns out that building reliable applications is hard and requires a lot of testing. You can write unit tests but quite often these all pass and the application is still broken. Why? Because they test parts of the application in isolation. But for a reliable application we need more. We need to make sure that all parts, including the backend API’s, work together as intended.
Cypress is a great tool to achieve this. It will test you complete web application in the browser and use it like a real world user would. In this session Maurice will show you how to use Cypress during development and on the CI server with Svelte. He will share tips and tricks to make your tests more resilient and more like how an actual end user would behave.

Angular universal
This document discusses Angular Universal, which allows Angular applications to render on both the server and client. It provides an overview of web history from static pages to single-page applications (SPAs) and the problem of increased load times and SEO issues with client-side rendering alone. Angular Universal solves this by combining server rendering with client rendering. Key points covered include pre-rendering, routing, syncing state between server and client rendering, and limitations to consider for server-side rendering with Angular.
React in production
In the talk we have covered how to manage React application in production, we focused on Webpack, caching, client side logs, error handling, NPM dependencies.
Multiplayer game with angular and firebase
This document discusses building a multiplayer game using Angular and Firebase. It introduces Phaser as a game framework for handling game logic and rendering. Angular is used for the browser UI and pre-game steps, while Firebase provides a real-time database for synchronizing game state across clients. The document explains how to initialize Phaser within Angular, load game assets, add player input handling, and sync the game with Firebase to enable multiplayer functionality.
How to: node js & micro-services
This document discusses how Node.js can help address challenges with microservices architectures. It outlines common problems like logging, configuration, health checks, and common logic that must be addressed across microservices. Node.js solutions like common logging packages, tracing middleware, and process managers like PM2 are presented as ways to solve these problems by creating reusable components and standardizing infrastructure across services. Examples of implementing common logging and tracing are provided to illustrate how Node.js can help build more maintainable microservices applications.
Javascript issues and tools in production for developers
1) Front-end code needs to be prepared for the varied environments and browsers that users will consume it in, as users can cause bugs and not follow test scenarios.
2) When issues arise, stories should be collected, reproduced, and fixes understood to prepare for the future. Error tracking and context logging are important.
3) Tools like Gulp and Grunt can be used to minify, concatenate, and version code for deployment to avoid caching issues and enable source maps for debugging minified code.

React vs angular (mobile first battle)
React Vs angular in the fight to be the best at mobile.
Reviews the native vs hybrid solution, also address both angular 1.x and angular 2.x
React vs-angular-mobile
This document compares Angular and React frameworks for mobile development, discussing hybrid solutions using Ionic and native solutions using React Native. It provides an overview of Angular and React, describing Angular as an MVC framework with two-way binding and React as a component-based library with unidirectional data flow. It then discusses Ionic as an Angular-based hybrid framework that allows access to some native APIs and React Native, which compiles JavaScript to native code for better performance and full native API access. In the comparison section, it summarizes that Ionic shares more code with the web but has limited performance and native capabilities, while React Native requires more platform-specific code but has native performance and full feature support.
MEAN.js Workshop

You could find the code: https://github.com/habmic/MeanDemoCode
AWS intro
In this talk we will take an "regular" solution and turn it into cloud solution, we will also see a bit code example in NODE.js
Angular Unit Test
The document discusses unit testing in Angular. It explains that there are three main parts to unit testing: the process to run tests, a test runner, and an assertion library. Karma is recommended as a test runner that works with Jasmine, a popular assertion library for writing Angular unit tests. The document provides examples of how to set up Karma and write unit tests using Jasmine's matcher methods and expectations. It emphasizes the importance of writing code in a testable way by isolating dependencies and single responsibilities.
Unit-testing and E2E testing in JS
Unit testing and end-to-end (E2E) testing are important types of automated testing for JavaScript applications. Unit tests focus on testing individual functions or components in isolation to catch bugs, while E2E tests ensure that user flows work as expected by interacting with the application through a browser. The presentation discussed setting up testing frameworks like Karma and Jasmine for unit testing and Protractor for E2E testing. It also covered writing testable code, handling dependencies through dependency injection, and selecting elements and interacting with them during E2E tests.
XAML/C# to HTML/JS
This document discusses transitioning from .NET/XAML development to web development using HTML, JavaScript, and TypeScript. It covers choosing TypeScript and a MVVM framework like Knockout to leverage existing skills in data binding, object-oriented programming, and requirements handling. The document demonstrates TypeScript features like classes, inheritance, interfaces and generics. It also shows how to implement the MVVM pattern in Knockout through data binding, commands, and iterating over collections.
XAML/C# to HTML5/JS
This document discusses transitioning from XAML/C# to HTML5/JavaScript using the Knockout library. It explains that while HTML5/JS doesn't natively support features like MVVM, Knockout provides data binding, collections, commands and other features to emulate the MVVM pattern. A comparison is made between XAML and Knockout, and the presenter encourages attendees to experiment with Knockout on their own to become more comfortable with the transition.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
Microservice Teams - How the cloud changes the way we work
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
