Web Development With Ruby - From Simple To ComplexBrian Hogan
Beyond the massive hype of Ruby on Rails, there's an amazing world of frameworks, DSLs, and libraries that make the Ruby language a compelling choice when working on the web. In this talk, you'll get a chance to see how to use Ruby to quickly build a static web site, create complex stylesheets with ease, build a simple web service, crete a simple Websocket server, and test your existing applications. Finally, you'll see a few of the ways Rails really can make developing complex applications easier, from advanced database querying to rendering views in multiple formats.
This presentation gives an overview of how we use Scala in Hulu's data platform, focusing on a couple of interesting features like its database interface layer (Slick), and parser combinators to implement DSLs
While python is widely used for automating administration tasks, it’s not still widely known and used between system administrators.
iPython is an interactive python shell that embeds bash functionalities. We’ll show how to :
* replace some bash tasks avoiding common errors
* resembling some bash behaviour
* create testing (nose) and monitoring scripts
* use flask to expose those scripts on HTTP
Il TechAdvisor Roberto Polli condivide l'esperienza maturata su iPython, una potente shell interattiva nata per affiancare la classica shell Bash comunemente utilizzata dagli amministratori di sistema. Attraverso degli esempi pratici mostra le principali differenze tra i due approcci ed aiuta a comprendere quale sia lo strumento più adatto a specifici casi d'uso.
Durante la presentazione mostra inoltre come:
- evitare errori comuni negli script bash;
- velocizzare la creazione di script per l'esecuzione di test mediante la libreria nose;
- riutilizzare moduli Python esistenti nella shell interattiva;
- usare il framework Flask per convertire facilmente gli script in web services.

Moving to Dojo 1.7 and the path to 2.0James Thomas
With the upcoming 1.7 release, The Dojo Toolkit is beginning to introduce major structural and architectural changes in the toolkit, setting the path for their new major 2.0 release due in 2012.
These fundamental changes to the architecture and technologies underpinning the toolkit will dramatically change how we write Dojo applications in the future, bringing with it huge benefits in performance, cross-library compatibility and support for mobile platforms.
In this presentation, I'll be walking through these changes, explaining the benefits and how it'll impact developers. I'll also be providing migration tips to help you start taking advantage of these benefits in your application today, based upon my experience using Dojo 1.7 on the Watson project.
This talk will be technical in nature, aiming at developers and team leads who are using the toolkit in their products or on client 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).

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.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
