The document discusses how Rich Internet Applications (RIAs) can be done effectively by leveraging modern web technologies like Ajax and RESTful web services. It advocates for building RIAs using a client-server architecture with thick clients that rely on RESTful APIs and lightweight markup from servers, as this allows for improved performance, mobility, and a better user experience compared to traditional web applications. It also provides examples of implementing RIAs using technologies like GWT, Flex, and RESTful web services.
How Pony ORM translates Python generators to SQL queriesponyorm
Pony ORM is an Object-Relational Mapper implemented in Python. It uses an unusual approach for writing database queries using Python generators. Pony analyzes the abstract syntax tree of a generator and translates it to its SQL equivalent. The translation process consists of several non-trivial stages.
This talk was given at EuroPython 2014 and reveals the internal details of the translation process.
s React.js a library or a framework? In any case, it is a new way of working that represents a revolution in the way of building web projects. It has very particular characteristics that allow us, for instance, to render React code from the server side, or to include React components from Twig tags. During this talk we will present React.js, we will explore how to take advantage of it from PHP projects and we will give answers to practical problems such as universal (isomorphical) rendering and the generation of React.js forms from Symfony forms without duplication of efforts.
Solving CSS Problems With eCSStender - An Event Apart - Chicago 2009Aaron Gustafson
Though the web is constantly evolving, browsers and standards bodies have been struggling to keep up. This is where eCSStender comes in. eCSStender is an open source JavaScript library that helps make CSS better by generating a platform that serves the dual need of smoothing out browser inconsistencies and innovating the language. In this session, Mr. Gustafson will debut eCSStender, show you how it works, and demonstrate how it can be used to solve real problems with CSS right now. At the end of this session, you will be able to wave goodbye to -moz- this and -webkit- that and say hello to using CSS the way it is meant to be.

This talk describes how to build RESTful JSON services using Python on Google App engine. It looks at how this can be done with straight webapp2, Google Cloud Endpoints, and a library I wrote called Pytracts.
WCF Data Services (formerly known as "ADO.NET Data Services") is a component of the .NET Framework that enables you to create services that use the Open Data Protocol (OData) to expose and consume data over the Web or intranet by using the semantics of representational state transfer (REST). OData exposes data as resources that are addressable by URIs. Data is accessed and changed by using standard HTTP verbs of GET, PUT, POST, and DELETE. OData uses the entity-relationship conventions of the Entity Data Model to expose resources as sets of entities that are related by associations.
When you write unit tests for your projects, there’s a fair chance that you do so by following the classical « Given-When-Then » paradigm, in which you set some input data, execute the code you’re testing, and finally assert that its outcome is indeed the one you expected.
While this approach is perfectly sound, it does suffer one downside: your program will only be tested on the static input data defined in your tests, and there is no real guarantee that this data does cover all edge cases. This can be especially problematic for SDK developers, who, by definition, have a very hard time anticipating all the different situations in which their code will be used.
To improve on this issue, another approach exists, and it is called property-based testing. The idea behind it is very simple: you write your tests by defining properties that must always be true for your program. For example, « an array reversed twice is always equal to itself ». The testing framework will then generate random input values and test wether the property holds or not. And, as you can imagine, this approach is extremely good at narrowing down on overlooked edge cases.
In Swift, we are lucky enough to already have a full-fledged implementation called SwiftCheck, that enables property-based testing (https://github.com/typelift/SwiftCheck). The goal of this talk is thus to explain how property-based testing can be a powerful addition to a testing suite, and give actual and actionable examples of how it can be added to a project using SwiftCheck.

Ajax is the web's hottest user interface. Struts is Java's most popular web framework. What happens when we put Ajax on Struts?
In this session, we look at writing a new Struts 2 application from square one, using the Yahoo User Interface (YUI) Library on the front end, and Struts 2 on the backend. YUI provides the glitz and the glamour, and Struts 2 provides the dreary business logic, input validation, and text formatting.
During the session, we will cover
* How to integrate an Ajax UI with Struts 2
* Basics of the Yahoo User Interface (YUI) Library
* Business services Struts can provide to an Ajax UI
Who should attend: Ajax developers who would like to utilize Struts as a back-end, and Struts developers who would like to utilize Ajax as a front-end.
To get the most from this session, some familiarity with an Ajax library, like YUI or Dojo, is helpful.

This is a talk I gave at AnDevCon. It talks about ways to take advantage of features introduced in Android 3.0 to create more modular and better looking apps.
That’s My App - Running in Your Background - Draining Your BatteryMichael Galpin
You have seen the ads where Android based devices like to brag about how awesome their multitasking is and now even the iPhone claims to have multitasking. Unfortunately it’s pseudo-multitasking borrowed from Android, but fear not. Android has “real” multitasking as well. It’s easy to do, but even easier to screw up. In this talk you’ll learn how to do it right, and how to do it without killing a phone’s battery. We’ll discuss the dreaded “P” word (polling), as well as alternatives such as Android’s cloud to device messaging and persistent connections.
Are the smartphone wars wearing your out? When asked to choose between Objective-C and Java do you answer “None of the Above”? Do you think app stores are so 1995? Then there is good news for you and it’s called the mobile web. This isn’t about trying to port iFart to the browser, and it’s definitely not about tweaking an existing website so it doesn’t look awful on your mom’s iPhone. It is about writing full featured, engaging applications on the web. This talk is all about how to create killer web apps using HTML5, CSS3, as well as some other not-so-standard technologies available on a wide variety of popular smartphones. We’re talking about multi-threaded, high performance apps that can track your movement or even take pictures of whatever you think is interesting.
This is brief presentation on the Scala programming language. It is aimed at Java developers who are curious about Scala. It was given at a San Francisco Java User Group in January 2009.

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.
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
