FirmLeak: A framework for efficient and accurate runtime estimation of leakage power by firmware
Arun Joseph, Anand Haridass, Charles Lefurgy, Spandana Rachamalla, Sreekanth Pai, Diyanesh Chinnakkonda, Vidushi Goyal
2015 28th International Conference on VLSI Design (VLSID),
3-7 Jan. 2015
Abstract:Separating the dynamic power and leakage power components from total microprocessor power can enable new optimizations for cloud computing. To this end, we introduce FirmLeak, a new framework that enables accurate, real-time estimation of microprocessor leakage power by system software. FirmLeak accounts for power-gating regions, per-core voltage domains, and manufacturing variation. We present an experimental evaluation of FirmLeak on a POWER7+ microprocessor for a range of hardware parts, voltages and temperatures. We discuss how this can be used in two applications to manage power by 1) improving billing of energy for cloud computing and 2) optimizing fan power consumption.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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.

Note 4: Definition of Response time
The response time is defined as the LCD optical switching time interval between “White” state and
“Black” state. Rise time (TON) is the time between photo detector output intensity changed from 90%
to 10%. And fall time (TOFF) is the time between photo detector output intensity changed from 10%
to 90%.
Note 5: Definition of color chromaticity (CIE1931)
Color coordinates measured at center point of LCD.
Note 6: Definition of Luminance Uniformity
Active area is divided into 9 measuring areas (Refer Fig. 2). Every measuring point is placed at the
center of each measuring area.
Luminance Uniformity (U) = Lmin/ Lmax
L-------Active area length W----- Active area width
Lmax: The measured Maximum luminance of all measurement position.
Lmin: The measured Minimum luminance of all measurement position.
Note 7: Definition of Luminance:
Measure the luminance of white state at center point.

10 Precautions for Use of LCD Modules
10.1 Handling Precautions
10.1.1 The display panel is made of glass. Do not subject it to a mechanical shock by dropping
it from a high place, etc.
10.1.2 If the display panel is damaged and the liquid crystal substance inside it leaks out, be
sure not to get any in your mouth, if the substance comes into contact with your skin or clothes,
promptly wash it off using soap and water.
10.1.3 Do not apply excessive force to the display surface or the adjoining areas since this
may cause the color tone to vary.
10.1.4 The polarizer covering the display surface of the LCD module is soft and easily
scratched. Handle this polarizer carefully.
10.1.5 If the display surface is contaMinated, breathe on the surface and gently wipe it with a
soft dry cloth. If still not completely clear, moisten cloth with one of the following solvents:
- Isopropyl alcohol
- Ethyl alcohol
Solvents other than those mentioned above may damage the polarizer. Especially, do not use the
following:
- Water
- Ketone
- Aromatic solvents
10.1.6 Do not attempt to disassemble the LCD Module.
10.1.7 If the logic circuit power is off, do not apply the input signals.
10.1.8 To prevent destruction of the elements by static electricity, be careful to maintain an
optimum work environment.
10.1.8.1 Be sure to ground the body when handling the LCD Modules.
10.1.8.2 Tools required for assembly, such as soldering irons, must be properly ground.
10.1.8.3 To reduce the amount of static electricity generated, do not conduct assembly and
other work under dry conditions.
10.1.8.4 The LCD Module is coated with a film to protect the display surface. Be care when
peeling off this protective film since static electricity may be generated.
10.2 Storage precautions
10.2.1 When storing the LCD modules, avoid exposure to direct sunlight or to the light of
fluorescent lamps.
10.2.2 The LCD modules should be stored under the storage temperature range. If the LCD
modules will be stored for a long time, the recommend condition is:
Temperature : 0℃ ~ 40℃ Relatively humidity: ≤80%
10.2.3 The LCD modules should be stored in the room without acid, alkali and harmful gas.
10.3 Transportation Precautions
10.3.1 The LCD modules should be no falling and violent shocking during transportation, and
also should avoid excessive press, water, damp and sunshine.
