Cloud computing is a large-scale and complex distributed computing paradigm where the configurable resources (servers, storage, network, data and software applications) are provided as multi-level services via virtualization technologies. Software aging is the biggest problem in Cloud Application.
I propose a novel and holistic software rejuvenation based fault tolerance scheme to counteract aging obstacles for cloud applications.
First, an adaptive failure detection and aging degree evaluation approach is proposed to predict which cloud service components deserve foremost to be rejuvenated. Second, a component rejuvenation approach based on checkpoints with trace replay is proposed to guarantee the continuous running of cloud application systems.
this project based on Fault Tolerance In Cluster Computing and this project is only Done in C language using Linux operating System. it uses MPICH2 package to handle and mpi commands to operate system.
Here is a Very Simple Description about Linker and Loader, and this will surly help all of you to understand logic of Linking And Loading regarding any Programming Language.

Taming startup dynamics - Magnus Jungsbluth & Domagoj Cosicmfrancis
OSGi Community Event 2016 Presentation by Magnus Jungsbluth & Domagoj Cosic (Bundesdruckerei GmbH)
If you had to name a single great thing about OSGi, it would probably be its dynamics. Services come and go; other services react to those events, configuration can change and so on. Even the startup is dynamic: start levels are increased synchronously; however, configuration, Declarative Services, and Blueprint are started asynchronously after bundles turn active. We love that but sometimes you want to exercise control over when your application is actually fully started or more importantly when it is not. You certainly do not want your system to be accessible with a security module that threw an exception during startup. Unlike monolithic applications, an OSGi application behaves more like a distributed system that converges to a final state eventually.
We will show you a way to monitor startup of your application by creatively using some common OSGi mechanisms and demonstrate failure scenarios for common subsystems like configuration and Blueprint. We will also demonstrate the concept of start phases which are a higher-level concept on top of OSGi start levels. A phased start enables a higher level of security in the face of failures during startup.

Embedded Linux Conference 2013
https://github.com/ystk/sched-deadline/tree/dlmiss-detection-dev
Real-time system need to meet deadline. In this point of view, the system is required two functions to have determinism. One is interrupt latency stabilization and the other one is processing time reservation. SCHED_DEADLINE has a feature to reserve CPU time in advance to ensure predictable behavior. However there is a lack of feature to control deadline missed processes.
In this presentation, we would like to discuss the requirement for the feature and also show a sample implementation to control deadline missed processes.

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.

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).
