This document provides instructions for setting up a Django development environment, including creating a Django project and application. It discusses installing virtualenv and Django, creating a project structure with manage.py, settings.py and urls.py files, setting up a SQLite database, creating models, forms and views for a TODO application, adding templates, and enabling the admin interface. The steps allow a user to build a basic TODO list application with Django to learn its core functionality and development process.
When working with enterprise applications, you want to have the same user experience that you know from for instance office applications and browsers. People know how to use the features that can be found in browsers such as bookmarking, favorites, and working with tabs. The search mechanism provided by Google, that uses suggestions based on the text typed by the user, is so common that people expect this in every application. And there are more of these UI patterns. In this session, you will learn how to implement some of the common UI patterns in your ADF application.
By the sum of PHPUnit assertion power and Symfony2 functional testing tools the developer can obtain a deep control on the developed application.
Here you can find some suggestions on how to leverage that power.
Silex is a brand new PHP 5.3 micro framework built on top of the Symfony2 de decoupled components. In this session, we will discover how to build and deploy powerful REST web services with such a micro framework and its embedded tools.
The first part of this talk will introduce the basics of the REST architecture. We fill focus on the main concepts of REST like HTTP methods, URIs and open formats like XML and JSON.
Then, we will discover how to deploy REST services using most of interesting Silex tools like database abstraction layer, template engine and input validation. We will also look at unit and functional testing frameworks with PHPUnit and HTTP caching with Edge Side Includes and Varnish support to improve performances.

Practical JavaScript Programming - Session 4/8Wilson Su
JavaScript is one of the most popular skills in today’s job market. It allows you to create both client- and server-side applications quickly and easily. Having a solid understanding of this powerful and versatile language is essential to anyone who uses it.
“Practical JavaScript Programming” does not only focus on best practices, but also introduces the fundamental concepts. This course will take you from JavaScript basics to advanced. You’ll learn about topics like Data Types, Functions, Events, AJAX and more.
This course will give you the knowledge you need to properly and effectively start integrating jQuery, the popular JavaScript library, into your web development projects. Over the course of two days, you'll learn the fundamental concepts of JavaScript and jQuery and tackle real-world exercises to solidify your understanding of the language and the library. This class is aimed at beginning jQuery users, although intermediate users may also benefit from the more formalized introduction to the library this class will offer.
We, as developers, often think that we don’t have to or don’t need to know what are what they call design patterns. We think that we already know how to build a software and don’t need all this theory. Years after years, by having to deal with the low maintainability of my own codebases, I explored a lot of ways of decoupling applications, in order to have enterprise-grade software that last for years. With concrete examples, I want to share with you some design patterns and how they can help you to grow well structured and decoupled applications.

Open-source projects often struggle with finding contributors and getting off of the ground. Communities, such as Github and PyPi, are host to redundant projects and libraries. In the development space, how do you distinguish your project from others, get people excited to contribute to it, and ultimately create a successful open source project? The answer is to apply user-centered design techniques to the development of your project. User-centered design is usually applied to web applications and products on the front-end of a website, but these techniques can be applied to open source libraries.
In this talk, Jackie will illustrate some user-centered techniques that have been used on her own project — Mesa (https://github.com/projectmesa/mesa), along with other successful open source projects. This talk will include a survey of interviews with a focus on successful techniques, along with additional user-centered design techniques that could be leveraged to inspire increased community engagement into your project.
It's not news how even some very high profile websites have suffered from serious performance issues owing to large hits on their websites- eventually resulting in monetary loss and above all loss of valuable customers. At Mindfire, with our expert team of Load and Performance testers, we help ensure that streamlined efforts are also being aligned towards this very important aspect of development.
Google App Engine in 40 minutes (the absolute essentials)Python Ireland

Creating and breaking a module in Drupal 8.
Configuration Steps: https://www.gitbook.com/book/zivtech/debug-tools-for-drupal8/details
Debug your PHP code efficiently without Devel module’s dpm(Drupal Print Message). With Drupal 8’s adoption of Symfony and object-oriented architecture, we need to adjust how we debug our code. Up until now, many of us have been using the convenient dpm function for debugging and introspection. However, dpm cannot print protected properties or provide information about methods of an object.
This makes it difficult to debug objects and classes. It’s time to learn a new approach! We will look at alternative methods to solve this problem such as:
Xdebug with PHPStorm configuration - http://xdebug.org
Devel and the WebProfiler (D8+) Drupal module https://www.drupal.org/project/devel
Using the continuous integration tool Probo CI to speed up the testing and approval process - http://probo.ci/
We will create a module, break it and use the above tools to debug, test and fix the code. Whether you are dipping your toes into object-oriented PHP or you're an advanced developer, everyone can benefit from debugging their code more efficiently.

Awesome State Management for React and Other Virtual-Dom LibrariesFITC
Presented at FITC's Web Unleashed 2017 conference
More info at www.fitc.ca/webu
Fred Daoud
Modernizing Medicine
Overview
Do you use React or any other virtual-DOM-based library that you love, but wonder about how to structure and manage application state? Perhaps you’ve looked at Redux, but got bogged down in boilerplate and action constants. Then you wondered about asynchronous actions. Does the list of libraries and dependencies that you need to solve common problems just keep piling up? Wasn’t React supposed to be a simple view library?
Let’s talk about other ways to manage the data flow of your web applications. We want a single state object, one-directional data flow, reactive views as plain functions, decoupled and reusable components, routing, time-traveling, …all without any fuss. We’ll assemble this in a way that lets you keep using your favourite libraries (React, Preact, Inferno, Snabbdom, Mithril, etc.), and write your code with regular JavaScript functions, giving you state management with the freedom to structure your application as best suits your requirements.
Objective
Show developers great ways to manage the state of applications using React or any virtual-DOM library.
Target Audience
Front-end JavaScript developers
Assumed Audience Knowledge
JavaScript and basic React or other virtual dom library.
Five Things Audience Members Will Learn
Managing application state with a single model and unidirectional flow
Creating decoupled, reusable components (with plain objects and functions!)
Assembling and composing with simple functional programming techniques
Routing made simple, using the library of your choice
Time-travelling and other cool development tools

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
