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).

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!

2. Measurement Principle
Goniophotometer with Moving Mirror (also called Goniphotometer with Rotating
Mirror) can test luminaries rotating in the prescribed burning position and around
the vertical axle and a reflecting mirror rotates around the horizontal axle,
meanwhile, a synchronous axle will rotate toward the opposite direction
synchronously. The photometer head located at a fixed position of the limiting
photometric distance in front of the reflecting mirror to gather the light in each
direction.
The rotation priority is determined by the software. If mirror axle is took precedence
of rotation, the goniophotometer will continuously measure the luminous intensity
at each γ angle on a vertical plane determined by the C angle, the measuring trace
is equivalent to the longitude. Similarly, while the luminaries axle is priority, the
system will continuously measure the luminous intensity at each C angle on a
conical surface determined by the γ angle, the trace can be looked upon the woof.
See the following figure.

reflected by the rotating mirror in the LSG-2000 system. The light given off
directly by the luminaries and reflected by the wall and floor is warded off
by the light fence. Internal surface of the dark room and dark path together
with the surface of the light fence should be painted unpolished black or be
covered by black cloth and black carpet.

Temperature around the lamp or luminaries must be 25℃±1℃ during the test.
Exceptions can be given according to relative lamps as following.
a. Tungsten Incandescent Lamp: 25℃±5℃
b. Double-caps Fluorescent Lamp: 25℃±1℃
c. High Pressure Mercury Lamp: 25℃±2℃
d. Metal Halogen Lamp: 25℃±2℃
e. High Pressure Sodium Lamp: 25℃±2℃
f. Low Pressure Sodium Lamp: 25℃±2
4) Airflow
Airflow may be induced by natural aeration, air conditioner or movement of the
luminaries in the goniophotometer, but the speed of the airflow couldn’t
exceed 0.2m/s.
5) Vibration and shock
When the lamp is in lighting, the vibration couldn’t exceed 10m/s2(4 ~
3000Hz), or the moving scope of the lamp couldn’t exceed 30mm (at most
4Hz)
6) Smoke, Dust and Moisture
The test environment must free from smoke, dust or moisture. At the same
time, even not during the measurement, smoke, dust or moisture will also
influence the reflectance of the reflecting mirror and induce more stray light.
So, the test room must be kept clean, no smoke and dry. The humidity should
be less than 60% RH.
6. Service
1) Installation and Training
LISUN GROUP engineers will take responsibility for installation and Training of
the system at the customer’s
2) Period of Guarantee: 24 months
The service is for free except technician’s travel payment if the service
provided by LISUN GROUP implement at the customer’s.
3) Upgrading the applications software for free

9. Application Software
This system can export data files as following formats:
This kind of format files can be transferred by other illumination and luminaire
design software such as DiaLux
Application software can also implement essential calculation for lighting design as
iso-illuminance distribution curve on a working plane, luminance limitation curve,
luminaire efficiency, effective beam angle, upward luminous flux ratio, downward
luminous flux ratio, effective luminous flux, utilization factor curve etc.
