“Digital democracy” helen milner digital leaders annual lecture 24 february 2015Helen Milner
My speech at the Digital Leaders Annual Lecture in February 2015 about Digital Democracy. Slides have notes of the full speech. This is about people and democracy more than technology. I talk about social media, the Arab Spring, the crowdsourced constitution in Iceland, and the Net Party in Argentina. I talk about the findings of the UK House of Common's Speaker's Commission on Digital Democracy - as a Commissioner. Not radical but perhaps a very quiet and polite revolution.
Design patterns are known and tested solutions to common problem. In software engineering we constantly come across similar problems. The same problems or tasks need to be programmed again and again, hence patterns. Design patterns catalog and document these solutions.They are built on industry knowledge of what works and why. We will look at what design patterns are, their history and the structure of documenting patterns.
As an example we look at the Observer pattern.
We will also look at Liskov Substitution Principle and the Open Close Principle, both which are very useful in building enterprise systems. Finally we look at creating objects.

Creating a Use Case
Introduction
With this paper I will show how a use case diagram should be used. I base this paper from fig. 3
– 11 pages 78 – 80 in our textbook titled: System Analysis and Design in a Changing World, 6th
edition, by Satzinger, Jackson, and Burd. In the Use Case Diagram that I make, I will depict a
use case for a RMO CSMS subsystem. I will also be describing the overview of the diagram. I
will also provide an analysis of the characters.
Use Case Introduction
An activity that a system performs is known as a use case. It is mostly in response to the
user. Use case analysis is a technique that is used for identifying the functional requirements of
the software system. A use case is to designate the point of view from a client and customer, this
is a use cases main purpose. An analytical role in the development process is done by the
developer. The other definition of a use case is as an objective or as an actor. Actors are with a
particular system and they want to achieve. In the use case diagram that I create, I will show the
actors and use cases for the RMO CSMS subsystem for marketing.
Marketing Subsystem
RMO CSMS
Marketing Merchandising
Overview
The overview of this use case diagram has the following: It shows the system boundary,
the association and the actors. The one that does the interaction with the system by entering or
receiving data is called a group, actor, external agent or person. Another part of the whole system
are the system boundaries. System boundaries are the computerized part of the application along
with the users who operate it. When a customer places a relationship between certain things such
as a certain employee in a department and an order, this would be a logical association. In my
diagram I have included two actors, one is representing marketing and the other represents
merchandising.
Analysis
The events and actions that define the interactions with a system and the role in order to
be able to discover a goal is a list of actions or steps in an event in a use case. The elements that
make up a use case diagram and the connections that are between a use case and the actors is an
association. This lets us know that there is communication between the actors and the use case.
On the marketing side they need to be able to update / add promotions, production and business
partners. On the merchandising side they need to be able to update / add production information
and accessory packages.
Summary
The important part of a use case diagram is that you can identi ...
Package diagram is used to simplify complex class diagrams, you can group classes into packages. A package is a collection of logically related UML elements.

I have been writing a lot about advanced topics like MVC, Entity Framework, Repository Patterns etc., my priority always remains to cover the topic as a whole, so that a reader do not have to search for missing links anywhere else. My this article will cover almost every OOPS concept that a novice/beginner developer hunt for, and not only beginners, the article’s purpose is to be helpful to experience professionals also who need to sometimes brush-up their concepts or who prepare for interviews .

There are many design principles that have become best practices over the years. Using these principles we can develop scalable and maintainable enterprise application with time tested approaches.
Hönnunarmunstur er þekktar og reyndar lausnir við almennum vandamálum. Hugbúnaðargerð felur í sér að leysa vandamál og oft rekumst við að sömu vandamálin aftur og aftur. Þessi vandamál má leysa með þekktum leiðum, svo kölluðum munstrum. Hönnunarmunstur skjala þekktar lausnir. Þau eru byggð á þekkingu úr iðnaðnum, segja hvað virkar og af hverju.
Í þessum fyrirlestri skoðum við hönnunarmunstur, sögu þeirra og hvernig þau eru skjöluð. Við lítum á ýmis dæmi og tökum svo fyrir grunnmunstur - base patterns. Þá skoðum við Open Close Principle sem er eitt af þessum prinsippum sem við þurfum að hafa í huga.

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).

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.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra 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!
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias 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.

Use case realization is the set of class diagrams and interaction diagrams that implement a use case
Data model that can be changed to domain model
There is no such thing as a "correct" list. It is a somewhat arbitrary collection of abstractions and domain vocabulary that the modelers consider noteworthy
Fact: Each responsibility is an axis of change. Reminder: We must agree that if a change occurred on a class, then all the dependencies must be: Rebuild Retest Redeploy Because we have many responsibilities then we have many reasons to change which means a huge rebuild, retest and redeploy for all the clients
Geometric Rectangle has less reasons to change which means less probability to change the class. But if you are sure it will change, then use Design Patterns (Strategy design pattern)
LSP violation means you need to re-design your abstractions hierarchy.
Through the discussion of SOLID principles, we show some useful principles to apply through the design by showing classes with problems and solving them; but we didn’t show how did we get these classes and how did we assign their responsibilities. In the following section we will talk about how to find the responsibilities and how to assign the proper responsibility to the proper class.
