Reliable Array of Independent Nodes
RAIN Technology

Existing Problems on Internet
• Single points of failures
They are devices that have no inherent
redundancy or backup.
• Bottlenecks
They are devices that do not have enough
processing power to handle the amount of traffic
they receive.
These two problems decrease the reliability and
performance of the network.

What is RAIN Technology?
 RAIN Technology originated at California Institute
Of Technology and its purpose was to overcome the
existing problems on the internet.
 A component that stores data across distributed processors and
retrieves it even if some of the processors fail.
 A communications component that creates a redundant network
between multiple processors and supports a single, uniform way
of connecting to any of the processors.
 A computing component that automatically recovers and restarts
applications if a processor fails.

Goals of RAIN Technology:
• RAIN technology was able to offer the solution by
minimizing the number of nodes in the chain connecting
the client and server
• By RAIN technology making the existing nodes more
robust and independent of each other

Features
•Communication:
Since the network is frequently a single point of
failure, RAIN provides fault tolerence in the
network
•Group Membership:
A fundamental part of fault management is
identifying which nodes are healthy and participating.
•Data Storage:
It is achieved through redundent storage schemes
like storing data over multiple disk.

•Original data can be recovered against nodes
failure.
•It provides dynamic reconfigurability.

DESIGN, CONSTRUCTION AND EVALUATION OF RAIN WATER HARVESTING SYSTEM FOR SBIT ...IAEME Publication

As the scarcity of water is rapidly increasing everyday particularly during the summer season, the demand for water also substantially increases. Previously around thirty to forty years back, the major part of the earth is unpaved and the amount of infrastructure built on the earth were also very low, hence during the monsoon season the rainwater easily percolates into the earth through the soil and the ground water level increases. But now the scenario is completely different, most of the areas have been paved and the chance of percolation of water is completely reduced. Hence to replenish the ground water table and also to re-utilize the rainwater for domestic and agricultural purposes, the rainwater harvesting method is adopted. The rainwater harvesting is simple collection or storing of water through scientific techniques where the rain falls. The rainwater harvesting not only helps in meeting the daily water usage but also helps in increasing the groundwater levels quality and quantity. Here in our project, we are going to adopt the roof-top rainwater harvesting method and implement it in college itself, without allowing the water to be wasted through the gutters. In this project main focus is to design the collection procedure, store the rainwater from rooftop of the main block building of Swarna Bharathi Institute of science & Technology, Khammam.

Midokura OpenStack Day Korea Talk: MidoNet Open Source Network Virtualization...Dan Mihai Dumitriu

OpenStack deployments for public or private clouds require overlay networking. Due to the scale and rate of change of virtual resources, it isn't practical to rely on traditional network constructs and isolation mechanims. Today's deployments require performance, resilience, and high availability to be considered truly production-ready. In this session, we deep dive into the MidoNet architecture, and process of sending a data packet across an OpenStack environment through a network overlay. A distributed architecture implements logical constructs that are used to build networks without a single point of failure, all while adding network functionality in a highly-scalable manner. Network functions are applied in a single virtual hop. By applying network services right at the ingress host, the network is free from unnecessary clogging and bottlenecks by avoiding additional hops. Packets reach their destination more efficiently with the single virtual hop. After this session, the audience will understand how distributed architectures allow efficient networking with routing decisions and network services applied at the edge. Also, the audience will understand how it is easier to scale clouds when the network intelligence is distributed.

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora

Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik

This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements. Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows. We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure. The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik

Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe. We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved? Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

Exploring Code Comprehension in Scientific Programming: Preliminary Insight...University of Hawai‘i at Mānoa

This presentation explores code comprehension challenges in scientific programming based on a survey of 57 research scientists. It reveals that 57.9% of scientists have no formal training in writing readable code. Key findings highlight a "documentation paradox" where documentation is both the most common readability practice and the biggest challenge scientists face. The study identifies critical issues with naming conventions and code organization, noting that 100% of scientists agree readable code is essential for reproducible research. The research concludes with four key recommendations: expanding programming education for scientists, conducting targeted research on scientific code quality, developing specialized tools, and establishing clearer documentation guidelines for scientific software.

Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AIdanshalev

If we were building a GenAI stack today, we'd start with one question: Can your retrieval system handle multi-hop logic? Trick question, b/c most can’t. They treat retrieval as nearest-neighbor search. Today, we discussed scaling #GraphRAG at AWS DevOps Day, and the takeaway is clear: VectorRAG is naive, lacks domain awareness, and can’t handle full dataset retrieval. GraphRAG builds a knowledge graph from source documents, allowing for a deeper understanding of the data + higher accuracy.

1. Name :- Pratik Gondaliya Roll No :- 13 Reliable Array of Independent Nodes RAIN Technology

2. Existing Problems on Internet • Single points of failures They are devices that have no inherent redundancy or backup. • Bottlenecks They are devices that do not have enough processing power to handle the amount of traffic they receive. These two problems decrease the reliability and performance of the network.

3. What is RAIN Technology?  RAIN Technology originated at California Institute Of Technology and its purpose was to overcome the existing problems on the internet.  A component that stores data across distributed processors and retrieves it even if some of the processors fail.  A communications component that creates a redundant network between multiple processors and supports a single, uniform way of connecting to any of the processors.  A computing component that automatically recovers and restarts applications if a processor fails.

4. Goals of RAIN Technology: • RAIN technology was able to offer the solution by minimizing the number of nodes in the chain connecting the client and server • By RAIN technology making the existing nodes more robust and independent of each other

5. Features •Communication: Since the network is frequently a single point of failure, RAIN provides fault tolerence in the network •Group Membership: A fundamental part of fault management is identifying which nodes are healthy and participating. •Data Storage: It is achieved through redundent storage schemes like storing data over multiple disk.

6. •Original data can be recovered against nodes failure. •It provides dynamic reconfigurability. Features of Data Storage
