This document appears to be notes from a presentation or discussion about the Ruby programming language and the Rubinius virtual machine. It includes definitions of key terms like parser, compiler, virtual machine and how Rubinius converts source code to an abstract syntax tree then to bytecode for the virtual machine. It also briefly discusses challenges of integrating and interoperating Rubinius with other systems.

Not advertising on Facebook? You’re missing out on potential traffic from the second largest internet website, with more than 800 million active users. And if you’re familiar with Google AdWords or Microsoft’s adCenter you’ll love Facebook’s self-serve image and text-based ads that let you advertise your own web page or even your own Facebook page or event. Twitter and LinkedIn offer similar programs.

"In March 2012, Japan’s leading mobile operator, NTT DOCOMO, introduced Shabette Concier, an advanced voice-activated personal agent service that enables customers to intuitively and directly operate services and smartphone features with voice commands. Millions of DOCOMO's subscribers are now using this service. This session explains Shabette Concier's distributed speech recognition architecture, and dialogue-understanding system design, with machine learning technologies and large-scale database systems. Learn why DOCOMO chose the AWS cloud and how DOCOMO engineers overcame all the difficulties from CEO-imposed time constraints, unexpectedly rapid service growth, usage spikes driven by marketing campaigns, and internal resistance to the use of cloud services. The session concludes with lessons learned from a telco's large-scale service development of a mobile app with the AWS cloud."

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. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024

Tobias Schneck

As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other? Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
