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!

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.
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.

4. The Fukushima DaiichiAccident Plant Designs (Covered by Tom Hafera) What Happened? Accident Progression Spent fuel pools Radiological releases Impact on US
17. The Real Catastrophe was from the Tsunami 26,000 (dead &missing) & 130,000 homeless (April 28, 2011) Lead four plants at Fukushima I to fuel damage and large releases of radiation
24. Plant Designs - Fukushima Dai-Ichi BWR is a Boiling Water Reactor Unit 1 is BWR/3 Units 2-4 are BWR/4 There are 56 Reactors in Japan (1-FBR, 4-ABWR, 29-BWR, 23-PWR) compared to 104 Reactors in the USA (35 BWRs & 69 PWRs) The Fukushima I reactors began operation in the 1970’s so they are all thirty - forty years old. Fukushima I Units 1-4 all are early vintage Mark I Containment Designs
25.
26. All AC power to the station was lost when the tsunami flooded the EDGs, which occurred about 1 hour after the earthquake.
27. At that point, the plant experienced a complete blackout (no AC electric power at all). Commonly called a “Station Blackout”.
34. Boiling began in the suppression pool and the drywell pressure began to increased in about 11 hours after the SBO.
35. In about 16 hours the water level in the core began to decrease and core degradation occurred (through some combination of zirconium oxidation and clad failure).
36. Venting occurred at about 23 hours after SBO and the hydrogen explosion occurred in the RB about 1 hour later.
46. DC power from batteries and/or the use of DC powered pumps were lost after 70 hours, which is phenomenal considering that they are only designed to last 8 hours.
47. Although sea water was injected within an hour after the loss of RCIC, it appears that water level continued to decrease in the RV and DW pressure increased. Significant pressure increases were observed in the RV.
54. DC power from batteries and/or use of DC powered pumps were lost after 35 hours (half the time when using only RCIC system for Unit 2), which is great considering that they are only designed to last 8 hours.
55. Sea water was injected within 6 hours after the loss of RCIC & HPCI, and it appears that water level continued to decrease in the RV and DW pressure increased. Core damaged was assumed to occur during this time period.
56. Venting of the DW was observed at 43 hours and at 64 hours after SBO.
91. Fukushima Observations Not a Public Heath Catastrophe Inconsequential to Earth/Tsunami Impacts The Fukushima event rating was provisionally increased from level 5 to level 7 by Japanese officials on April 12, due to computer analyses indicating total discharged iodine-131 and caesium-137 in the early days of the event were sufficient to warrant an increased rating level. This rating increase did not reflect any new event. The radioactive release from Fukushima is very roughly estimated by Japanese officials to be about 10 percent of that released from the Chernobyl accident – with very important differences.
92. Fukushima Observations Not a Public Heath Catastrophe The most important difference between Chernobyl and Fukushima is no deaths or illness among the public are expected from the Fukushima incident. The Chernobyl accident emitted radioactive particles high into the atmosphere, which spread downwind across Europe, and a reactor fire continued this process for at least 10 days. Radiation from the Fukushima incident is mostly in the form of liquid runoff into the ocean and low-altitude particles that have frequently blown out into the ocean. At Fukushima, the reactor fuel remains inside the primary containment structures, whereas the Soviet Chernobyl design did not have a containment structure.
93. Fukushima Observations What is the risk of radioactivity getting into the US food supply? Normally very little food from the Fukushima region is imported into the USA. Affected foods from the region around the Fukushima plant have been banned from export by the Government of Japan. Any food from that area not already restricted by the Government of Japan will be detained for testing by the U.S. Food and Drug Administration (FDA) and not allowed into the USA unless shown to be absolutely free of contamination.
94. Three Mile Island History Reactor Scram: 04:00 3/28/79 Core melt and relocation: ~ 05:00 –07:30 3/28/79 Hydrogen Deflagration: 13:00 3/28/79 Recirculation Cooling: Late 3/28/79 Phased Water Processing: 1979‐1993 Containment Entry: July 1980 Reactor Head removed and core melt found: July 1984 Start Defuel: October 1985 Shipping Spent Fuel: 1988‐1990 Finish Defuel: Jan 1990 Evaporate ~2M gallons Processed Water: 1991‐93 Cost: ~$1 Billion
95. Impact on US Reactors US has implemented B.5.b requirements in 2008 Beyond Severe Accident Guidelines Onsite high pressure portable pump Procedures and appropriate staging areas and requirements for fire hoses and equipment on site MOUs with fire local fire stations to establish the plant as a priority in case of an emergency.
96. Impact on US Reactor Some of the things that should be reviewed Review all external events, i.e., fire, flooding, explosions and earthquake, to ensure that there is backup emergency equipment that can support a station black out. Review training for extreme station Blackout events and procedure. Ensure that emergency batteries are qualified for worst case events for fl0od, fire, explosions and seismic. The portable high pressure pump and associated equipment that was required because of B.5.b should be housed in a structure that is qualified for worst case fire, flood, explosion and seismic events.
