The document discusses Docker and containers. It explains that Docker manages containers which share the host system's kernel and are isolated from each other. Containers have fast boot times and low overhead. Docker images are templates used to create containers. The document demonstrates how to build a web application using Docker images, Docker Compose to define and run multi-container applications, and Docker Machine to provision virtual machines for development. It shows how containers can be used to develop applications incrementally and focus on software development.

Solidariteit en de waarde van cultuur

Socius - steunpunt sociaal-cultureel werk

Presentatie Quirijn van den Hoogen - Socius Trefdag 'Solidariteit?!' (20 november 2014) Wat levert dat eigenlijk op, investeren in cultuur? Wat zijn de echte meerwaarden verbonden aan cultuur en hoe vinden we daar bewijs voor? Om een antwoord te geven op dergelijke prangende vragen startten een 15-tal actoren uit de brede cultuursector, waaronder ook Socius, een collectief onderzoek. Uit het onderzoek blijkt onder meer de belangrijke rol die cultuur speelt bij het bevorderen van de sociale cohesie, het bereiken van kansengroepen en het zorgen voor verbinding in onze samenleving. Onderzoeker Quirijn van den Hoogen (Rijksuniversiteit Groningen) overloopt met ons de belangrijkste resultaten maar gaat ook in op de vraag wat het betekent dat we bewijs nodig hebben voor de werkzaamheid van cultuur en hoe dat vandaag de dag vooral wordt verzameld en geïnterpreteerd.

Socius - steunpunt sociaal-cultureel werk

Presentatie Maarten Loopmans - Socius Trefdag 'Solidariteit?!' (20 november 2014) Aan solidariteit zit een belangrijk ruimtelijk aspect: lokaal, nationaal en internationaal. Solidariteit overstijgt (culturele) grenzen en krijgt daardoor ook vaak een andere invulling. Sociaal geograaf Maarten Loopmans (KULeuven) bekijkt in deze sessie solidariteit vanuit een ruimtelijk perspectief. Maarten Loopmans is als sociaal geograaf verbonden aan de KUL en de Erasmus Hogeschool Brussel.

Deep Learning Demystified - A (Mostly) Effortless Introduction: AWS Developer Workshop at Web Summit Speaker: Gabe Hollombe - Technical Evangelist, AWS Getting started with deep learning can feel really intimidating. In this session I'll dive right in to explaining the basic concepts of deep learning with barely any jargon and only a bit of high-school math. We'll see how easy it is to take an existing pre-trained general-purpose image classification model from the cloud and re-train it to identify objects from a specific business domain. I'll show how to do all of this with python, using a Jupyter notebook hosted from Amazon Sagemaker (a service from AWS that makes it easy to develop, train, and deploy deep-learning models in the cloud). Finally, we'll finish up with a review of where to continue learning more.

How can you help your company evolve, adapt, and succeed using Artificial Intelligence and the Metaverse to stay ahead of the competition? What are the potential issues, complications, and benefits that these technologies could bring to us and our organizations? In this session, Jen Stirrup will explain how to start thinking about these technologies as an organisation.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs

Alex Pruden

This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra 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!

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.

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.
