Spark and Shark: Lightning-Fast Analytics over Hadoop and Hive DataJetlore
Spark is an open source cluster computing framework that can outperform Hadoop by 30x through a combination of in-memory computation and a richer execution engine. Shark is a port of Apache Hive onto Spark, which provides a similar speedup for SQL queries, allowing interactive exploration of data in existing Hive warehouses. This talk will cover how both Spark and Shark are being used at various companies to accelerate big data analytics, the architecture of the systems, and where they are heading. We will also discuss the next major feature we are developing, Spark Streaming, which adds support for low-latency stream processing to Spark, giving users a unified interface for batch and real-time analytics.
The talk present a new Data Aggregation System for CMS experiment at CERN. We use MongoDB database as caching layer to query multiple data-provides (backed up by RDMS) and aggregate data across them.
Talk has been presented at ICCS 2010 conference.

Scaling Big Data Mining Infrastructure Twitter ExperienceDataWorks Summit
The analytics platform at Twitter has experienced tremendous growth over the past few years in terms of size, complexity, number of users, and variety of use cases. In this talk, we’ll discuss the evolution of our infrastructure and the development of capabilities for data mining on “big data”. We’ll share our experiences as a case study, but make recommendations for best practices and point out opportunities for future work.

V-Kid Knowledge Boost (VKKB) Program: Gifting of Education to V-kids
PARD, in its pursuit to promote educational standards through enhancement of competitive spirit among early school going children in rural areas (we call them V-kids who are often denied with the equal opportunities in their up-bringing, study environment and exposure to the competitive world), has been pioneering “V-kid Knowledge Boost (VKKB)” program.
The presentation covers highlights of VKKB programs organized for the last three (3) years.
This document aims to specify the service design of the ARIADNE Portal, and provide a common vision, a user perspective on the functionality, and a framework to identify, discuss and validate the requirements for the underlying technical services. As such, the audience of this document will be both technical and non-‐technical.

On a Deterministic Property of the Category of k-almost Primes: A Determinist...Ramin (A.) Zahedi
In this paper based on a sort of linear function, a deterministic and simple algorithm with an algebraic structure is presented for calculating all (and only) k-almost primes (where ∃n∊ℕ, 1 ≤ k ≤ n) in certain intervals. A theorem has been proven showing a new deterministic property of the category of k-almost primes. Through a linear function that we obtain, an equivalent redefinition of the k-almost primes with an algebraic characteristic is identified. Moreover, as an outcome of our function’s property some equalities which contain new information about the k-almost primes (including primes) are presented.

NoSQL is not a buzzword anymore. The array of non- relational technologies have found wide-scale adoption even in non-Internet scale focus areas. With the advent of the Cloud...the churn has increased even more yet there is no crystal clear guidance on adoption techniques and architectural choices surrounding the plethora of options available. This session initiates you into the whys & wherefores, architectural patterns, caveats and techniques that will augment your decision making process & boost your perception of architecting scalable, fault-tolerant & distributed solutions.
What is NoSQL? How does it come to the picture? What are the types of NoSQL? Some basics of different NoSQL types? Differences between RDBMS and NoSQL. Pros and Cons of NoSQL.
What is MongoDB? What are the features of MongoDB? Nexus architecture of MongoDB. Data model and query model of MongoDB? Various MongoDB data management techniques. Indexing in MongoDB. A working example using MongoDB Java driver on Mac OSX.
If NoSQL is your answer, you are probably asking the wrong question.Lukas Smith
This session is not about bad mouthing MongoDB, CoachDB, big data, map reduce or any of the other more recent additions to the database buzzword bingo. Instead it is about looking at how NoSQL is a confusing term and a more realistic assessment how old and new approaches in databases impact todays architectures...
NoSQL Data Stores in Research and Practice - ICDE 2016 Tutorial - Extended Ve...Felix Gessert
The unprecedented scale at which data is consumed and generated today has shown a large demand for scalable data management and given rise to non-relational, distributed "NoSQL" database systems. Two central problems triggered this process: 1) vast amounts of user-generated content in modern applications and the resulting requests loads and data volumes 2) the desire of the developer community to employ problem-specific data models for storage and querying. To address these needs, various data stores have been developed by both industry and research, arguing that the era of one-size-fits-all database systems is over. The heterogeneity and sheer amount of these systems - now commonly referred to as NoSQL data stores - make it increasingly difficult to select the most appropriate system for a given application. Therefore, these systems are frequently combined in polyglot persistence architectures to leverage each system in its respective sweet spot. This tutorial gives an in-depth survey of the most relevant NoSQL databases to provide comparative classification and highlight open challenges. To this end, we analyze the approach of each system to derive its scalability, availability, consistency, data modeling and querying characteristics. We present how each system's design is governed by a central set of trade-offs over irreconcilable system properties. We then cover recent research results in distributed data management to illustrate that some shortcomings of NoSQL systems could already be solved in practice, whereas other NoSQL data management problems pose interesting and unsolved research challenges.

We prepared a small 30 min workshop for the Dutch Java User Group to introduce MongoDB basics. This slideshow contains the mongoDB concepts, which will be workout basic in labs . The labs could be found at: http://mongodb.info/labs/
Vote NO for MySQL - Election 2012: NoSQL. Researchers predict a dark future for MySQL. Significant market loss to come. Are things that bad, is MySQL falling behind? A look at NoSQL, an attempt to identify different kinds of NoSQL stores, their goals and how they compare to MySQL 5.6. Focus: Key Value Stores and Document Stores. MySQL versus NoSQL means looking behind the scenes, taking a step back and looking at the building blocks.

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
