ADF Mobile: 10 Things you don't get from the developers guideLuc Bors
Real Life ADF Mobile: 10 things you don't learn from the devguide
Oracle ADF Mobile has been around for over a year by now. There is a great developer guide available for everybody who wants to create an ADF Mobile application. However, when you are building your first ADF Mobile application you will definitely run into issues that cannot be solved by reading the developer guide.
Think of performance issues when taking pictures with modern devices. Images can take up to 5 Megabytes. What can you do to create a grid like springboard ? These are all topics not covered by the developer guide or by any available ADF mobile training.
In this session you will learn solutions for these and more real life ADF Mobile issues.
An introduction to Express, the Sinatra-inspired MVC framework for Node.JS. You'll learn how Express manages and processes routes, how to use the Jade template engine, and how to design data models aimed to play nice with Express.
Integrating React.js Into a PHP ApplicationAndrew Rota
React.js has taken the web development world by storm, and for good reason: React offers a declarative, component-oriented approach to building highly-scalable web UIs. But how can we take advantage of a JavaScript library like React in our server-side PHP applications. In this talk l cover the different ways React.js can be integrated into an existing PHP web application: from a client-side only approach to multiple techniques that support full server-side rendering with a Node.js server or PHP’s v8js. I also discuss the trade-offs in each of these designs and the challenges involved with adding React to a PHP site. Most importantly, I consider the higher-level issue of how to improve view cohesion across the client-server divide in a PHP application.
Word Play in the Digital Age: Building Text Bots with TracerySarah Sexton
Life is filled with moments of unexpected laughter. In this technical talk, walk through how to create your own comedy with an exciting mad-lib style JavaScript tool: Tracery! Kate Compton’s templating language, free and open source, is a multipurpose text-expansion library. It can be used to generate text for your NPC dialog, gameplay collectibles, twitterbots, chat bots, and more! Learn how to take a piece of text with #tags# in it, replace the text between the two hashtags with a replacement rule, and fill in the blanks with unpredictable diction. Come find out what bizarre stories you can write in a way that is easy and fun to program.

Velocity EU 2014 — Offline-first web appsandrewsmatt
The upcoming HTML5 feature known as Service Worker is set to turn the web on its head, enabling websites to run without an internet connection and to load quickly even when the connection is bad.
But with that evolutionary step, web applications need to become more complex, and to handle the fact that their source code may remain on a device for much longer than a single session. Without the safety net of starting fresh every time the user hits a link, considerations such as memory management, data consistency, encapsulation and backwards compatibility now come into play. Front-end developers are suddenly fully-fledged software engineers! The web page is our app platform, and the browser our runtime.
The fastest byte is a byte not sent, so the fastest website is the website that doesn’t need to load anything. Step with me into a world of good hacks, unbeatable performance and smart, multivariate responsiveness, drawn from experience building web apps for the FT and The Economist.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

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.

43. What is OAuth 2.0?
§ OAuth
2.0 is a framework for allowing apps to
securely access data on behalf of users
§ A more
secure alternative to asking for a user’s
password
44. Types of OAuth
§ Client-side
§ Best
for browser-based applications
§ No client_secret required, so it’s safe to use in
Javascript apps
§ Server-side
§ Requires client_secret,
so cannot be used from
a Javascript app without a proxy
45. Simple OAuth 2.0 Example
§ Use
the “implicit” grant type to generate an
access token directly in the browser
§ No
server-side code required
§ Browser
makes API calls directly to secure
services with the access token
46. Step 1: ArcGIS Developer Subscription
§ Sign
up for a subscription
§ Register
§ Enable
your apps
for OAuth
50. Step 3: Acquire a token
On success, user is redirected back to your site with the
access token in the fragment
https://example.com/auth#token=ACCESS_TOKEN
On error, user is redirected back to your site with error
code
https://example.com/auth#error=access_denied
51. Using the Access Token
§ Parse
out the access token
§ Make API
requests using the token
var accessToken;!
!
window.oauthCallback = function(token) {!
accessToken = token;!
}!
!
// Access services with token!
L.esri.get("http://route.arcgis.com/arcgis/rest/services!
World/Route/NAServer/Route_World/solve", {!
token: accessToken,!
stops: s.lng+","+s.lat+"; "+e.lng+","+e.lat,!
