Judy Weedman presentation for "More Than Meets the Eye? Retrieving Art Images by Subject" session at VRA + ARLIS/NA 2nd joint conference in Minneapolis, MN.
Requirements Elicitation is a technical and analytical process, but it is also a highly social and potentially emotive activity. All but the smallest software developments can have a wider organisational impact and the potential to change people’s working lives in positive and negative ways. Users’ reactions to such changes are shaped by their own personal values, motivations and emotions. Exploring and understanding such information can help requirements analysts in:
■Developing a deep understanding of users’ long term goals, working practices, preferences and problems
■Making design decisions
■Building a rapport with users
■Anticipating user wants and needs
Sarah Thew has been exploring these ideas during her PhD, carrying out a series of interviews with novice and experienced analysts investigating if and how they consider users’ values, motivations and emotions. These interviews contributed to the development of a method to support analysts in considering and exploring values, motivations and emotions during the requirements elicitation process, which she is currently evaluating.
When analyzing and designing a product, service, or system, minor adaptations to existing design processes can go a long way to expand beyond a techno-centric system perspective, or an exclusively "convenience and ease of use" user experience profile. By assigning critical questions to each step of a design process, we can resituate our working understanding of a technical system within its human context and expand our sociotechnical analysis to include matters of normative and ethical concern. These critical questions address concerns including inclusivity, duty of care, sustainability, and prevention of harm. From the newly expanded ethical context these questions help construct, it is possible to imagine opportunities for value-led change within the relationships of a sociotechnical system.
Normative Research Director Rebecca Pardo gave a series of presentations as an internal "workshop" with the Normative team to discuss research in a design context. This is the first of the series.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex 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).

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.

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.

6. Root definition
Definition:
‘A system to paint the garden fence’.
Root definitions are complex BUT NOT definitive:
‘A householder-owned and staffed system to paint the
garden fence, by hand-painting, in keeping with the overall
decoration scheme of the property in order to enhance the
appearance of the property’.
7. Investigating and understanding
unstructured problems
The investigation of a situation (case) should provide a
written agreement between the systems analyst
(remember the ‘systems analyst’ could be ‘you’ or ‘you +
team’) and the owner of the problem (one or several
‘stakeholders’). This often forms the basis for the design
of the solution service, product or system (depending on
the scope of the problem/solution)
Agreement between analyst and the owner of the
problem is essential so that both parties are clear as to
what the problem is before a solution design is sought.
8. The unstructured situation
Understanding a new place you have just
arrived at - e.g. on holiday
A new company that you have just started to
work for
studying an organisation as part of your
degree course - Organisation Study
A case study that you have been provided as
an assignment
9. Understanding unstructured
situations
Unstructured means - “not formally or
systematically organised:loose, free, open
etc,” - this may seem to be in contradiction to
the term “organisation” itself.
Exploring and understanding an unstructured
situation requires objective investigation and
analysis
e.g. Why are hospital waiting lists in the UK too long?
10. Exploring the Unstructured Situation
Initially,
the problem owner has identified that something is
wrong or that something needs improving
Critical analysis is usually applied:
Approach the problem with an open mind
View the problem from multiple perspectives
(particularly technological, organisational and people
perspectives)
The analyst engages in fact finding using
conventional methods, including:
interviews, observing, reading background material
and documentation, providing questionnaires and
measuring processes.
11. Exploring the Unstructured Situation
The analyst gains a mental picture of the
unstructured situation.
Identifies
roles,
responsibilities,
processes and
accepted norms.
Produces a definition of the unstructured
situation, by using, for example:
Rich pictures and/or CATWOE
12. Rich Picture
A rich picture is a sketch or diagram, using specific
symbols, usually hand drawn, that depicts these key
aspects of a situation:
the organisational structure
the physical characteristics of the situation, buildings
etc.
the processes that are carried out by the
situation/system
the relationship between processes
issues expressed or felt by individuals in the situation -
complaints, criticisms, feelings etc
13. Commonly used symbols
A few symbols are commonly used to describe certain entities within
the situations. But these symbols are not prescriptive and any such
pictorial representations may be used.
Movement or Transportation
External Scrutiny
Conflict or disagreement
A person in roleA thought or opinion
A relationship

15. The Rich Picture – more art than science?
Holistic, ongoing, subject to revision as
problem is further investigated …
Hazards include:
assumptions made must be justified
small issues can be blown out of proportion
too much detail will obscure the overall
richness of the picture
too little detail will not serve the purpose of
the picture.
16. Drawing rich pictures
The rich picture techniques may appear
childish at first but can be a very powerful tool
in understanding an unstructured situation …
17. Purpose of the Rich Picture
1. To help visualise the complex (unstructured)
situation from all its many perspectives
2. To avoid imposing a rigid structure on the
appreciation of the problem situation
3. To aid an investigative approach by the analyst
4. To act as a communication tool between
participants
18. The Relevant System
The rich picture is a pictorial representation of the
problem situation
In order to move on this needs to be viewed from a
systemic point of view – using the Soft Systems
approach, this is known as the “relevant system”
The relevant system should be discussed and agreed
between all involved parties
It is expressed by the use of a root definition –
describing the essence of the relevant system
