Mr. Ravi Shankar Gopal | Roadmap for growth in nonwovens industry in india
The document outlines opportunities and challenges for growth in the nonwovens industry in India. It notes that per capita consumption of nonwovens in India is much lower than in countries like the US, representing significant growth potential. However, the industry faces challenges like a lack of domestic raw material suppliers and need for imported equipment, making projects capital intensive. It recommends that major international players invest in key market segments in India like personal care, hygiene, and medical disposables to help create a base for the industry and drive application development and import substitution. The need of the day is attracting strategic investment from global leaders in areas with high growth potential.
New Products - Template and Roadmap Best Practices
The document outlines the new product development process which includes concept development, market assessment, product building, marketing, sales and aftersales. It involves defining the product concept, conducting a feasibility study and market assessment, ranking potential products, defining a timeline, writing an internal strategy brief, resource planning, and getting buy-in from teams. The process aims to bring new products from the concept stage through approval, piloting, and launch.
Reverse Engineering for exploit writers
The document discusses reverse engineering binaries to reconstruct missing symbol and section header information. It provides an overview of the ELF file format and issues with stripped binaries. It then describes heuristics and techniques for rebuilding symbol tables and section headers to allow analysis with standard tools like objdump and gdb. Examples are given of finding function labels like main() and global constructors/destructors. The goal is to refactor binaries as little as possible to make them usable again without affecting execution.
Asap roadmap
The document discusses the AcceleratedSAP (ASAP) methodology for implementing SAP solutions. It describes the five phases of the ASAP implementation roadmap: 1) Project Preparation, 2) Business Blueprint, 3) Realization, 4) Final Preparation, and 5) Go-Live and Support.

Includes a brief intro to Smalltalk design principles and Pharo Smalltalk. Also some demos to show how Smalltalk embraces a new way of understanding programming as a dialogue with your live objects in a running system.
Velocity conf 2013 freedom in disguise - khushil dep
This document discusses the concept of an autonomic cloud platform and operations engineering. It proposes using CFEngine as a configuration management tool to allow machines to manage themselves autonomously based on constraint models defined by users. This would maximize hardware performance and scalability while allowing deep system introspection and flexibility. Key aspects are recommended technologies like SmartOS, Joyent cloud, and DTrace for monitoring. The goal is for machines and humans to work as a team through evolving communication, trust, and a theory of mind approach rather than imperative commands that do not suit autonomous machine operation.
Moore for less
The document discusses the agile practices of 1960s programmers, noting that they wrote whole operating systems and applications from just a handful of machine instructions (the "MVP"). Programmers in this era understood principles now considered agile such as writing their own domain-specific languages, keeping software simple, and avoiding speculation. They were able to port code between different machines and achieve agility even with computers that had only a few kilobytes of memory and storage. The summary questions who now considers today's software to be heavyweight, slow, and clunky in comparison.

COSMOS - DNAi
COSMOS is a proposed 6th generation programming language that describes a digital world and objects within it rather than directly programming behaviors. It runs simulations to allow software entities to learn and evolve autonomously within the defined environment to achieve goals. The technology behind COSMOS is inspired by DNA and aims to produce "DNA Intelligence" whereby software worlds learn through comparison rather than being fully programmed. It works by defining needs, actions, rules and other parameters to simulate how living organisms evolve based on their DNA programming.

The Emo Spark is a 90mm cube that uses artificial intelligence to interact with users based on their emotions. It can detect emotions like joy, sadness, trust and more using face tracking and content analysis. Over time, it builds an emotional profile graph of each user to better understand their preferences. The cube can communicate through conversation, play music and videos tailored to the user's emotions. It has various hardware components like a CPU, memory and custom emotion processing unit. The cube can connect to other devices and share media with other cubes based on similar emotional profiles. It aims to enhance how users experience media like music by understanding their emotional responses.
Flow based-1994
This document provides an introduction and background about the author. The author was born in London before World War II and studied anthropology. He joined IBM in 1959 and became fascinated by symbolic logic and computers. Over 33 years at IBM in different countries, he observed many programming techniques and approaches but found that none delivered the large productivity improvements that were sought. He began focusing on why application development should be so difficult given computers' capabilities.

Cs8392 u1-1-oop intro
This document provides an overview of an Object Oriented Programming course taught by Rajasekaran S. The course covers 5 units: introduction to OOP and Java fundamentals, inheritance and interfaces, exception handling and I/O, multithreading and generic programming, and event driven programming. It defines key OOP concepts like objects, classes, abstraction, encapsulation, inheritance, and polymorphism using examples like cars. The document also lists the prerequisites for the course as a computer with Java installed, internet access, a text editor or IDE like Eclipse, and a reference book.
Learnig describes with Machine learning
This document discusses learning and machine learning. It defines learning as a relatively permanent change in behavior resulting from experience. Machine learning is described as enabling computers to learn from experience and adapt without being explicitly programmed. The goal of machine learning is to build systems that can learn from data rather than relying only on explicit programming. It is argued that machine learning is important for developing more intelligent artificial systems that can learn from mistakes like humans rather than always producing the same outputs.
PHP Unit-Testing With Doubles
Unit testing involves testing individual units or modules of code to determine if they work as intended. It is important because it finds problems early, facilitates change, simplifies integration, acts as documentation, and saves time. Unit tests work by being independent, automatic, fast, and isolated from external systems. Isolation is achieved through test doubles like dummies, stubs, mocks, and fakes that stand in for real objects to simplify testing.
What is knowledge representation and reasoning ?
Knowledge representation is a field of artificial intelligence that represents information about the world in a way that a computer system can understand to perform complex tasks. It simplifies complex systems through modeling human psychology and problem-solving. Examples of knowledge representation include semantic nets, frames, rules, and ontologies. Knowledge representation allows for automated reasoning about represented knowledge and asserting new knowledge. While first-order logic provides powerful and compact representation, it lacks ease of use and practical implementation for real-world problems. Effective knowledge representation requires balancing expressive power with practical considerations like execution efficiency.
Natural language processing(AI UNIT 2)
This document provides an overview of various topics in natural language processing including speech recognition, natural language understanding, natural language generation, chatbots, and machine translation. It discusses key aspects of each topic such as how speech recognition works, the challenges of natural language understanding, and how machine translation systems have evolved to consider context and domain specificity.

What is inheritance- How is it useful- Discuss 3 advantages and disad.docx
What is inheritance? How is it useful? Discuss 3 advantages and disadvantages of Object Oriented Programming over traditional procedural programming.
Solution
What is inheritance? How is it useful? Inheriance is the concept of reusing the readily available code. It is building a new set of classes on some existing classes. Instead of re-writing the code again, just using the existing code, and building on top of it. Inheriting the properties of a base class, into a derived class, and ofcourse derived class is allowed to have its own unique properties.
d. Advantages of OOP over POP.
1. Object orientation is more secure. Data is not flowing freely over the machine/memory. All the data, and the methods that are allowed to operate on the data are tied together and is called object.
2. Will communicate with outside world or other objects usually through the public methods which are allowed to communicate.
3. Provides some standard template libraries called STLs, so that we can make use of them. Polymorphism, inheritance will make the classes more robust.
The disadvantages include:
1. Mostly the objects are abstract, and will restrict to access low-level or hardware level resources directly.
2. OOP programs are slower than POP programs, because of the code they are supposed to compile/run.
3. OOP classes are larger in size when compared to POP raw codes.

Puppet camp2021 testing modules and controlrepo
This document discusses testing Puppet code when using modules versus a control repository. It recommends starting with simple syntax and unit tests using PDK or rspec-puppet for modules, and using OnceOver for testing control repositories, as it is specially designed for this purpose. OnceOver allows defining classes, nodes, and a test matrix to run syntax, unit, and acceptance tests across different configurations. Moving from simple to more complex testing approaches like acceptance tests is suggested. PDK and OnceOver both have limitations for testing across operating systems that may require customizing spec tests. Infrastructure for running acceptance tests in VMs or containers is also discussed.

It includes information about Corey Osman and NWOPS, as well as sections on efficient development, presentation content, demo main points, Git strategies including single branch and environment branch strategies, and workflow improvements. Contact information is provided at the bottom.
2021 04-15 operational verification (with notes)
The document discusses operational verification and how Puppet is working on a new module to provide more confidence in infrastructure health. It introduces the concept of adding check resources to catalogs to validate configurations and service health directly during Puppet runs. Examples are provided of how this could detect issues earlier than current methods. Next steps outlined include integrating checks into more resource types, fixing reporting, integrating into modules, and gathering feedback. This allows testing and monitoring to converge by embedding checks within configurations.

This document provides tips and tricks for using Puppet with VS Code, including links to settings examples and recommended extensions to install like Gitlens, Remote Development Pack, Puppet Extension, Ruby, YAML Extension, and PowerShell Extension. It also mentions there will be a demo.
Modules of the twenties
- The document discusses various patterns and techniques the author has found useful when working with Puppet modules over 10+ years, including some that may be considered unorthodox or anti-patterns by some.
- Key topics covered include optimization of reusable modules, custom data types, Bolt tasks and plans, external facts, Hiera classification, ensuring resources for presence/absence, application abstraction with Tiny Puppet, and class-based noop management.
- The author argues that some established patterns like roles and profiles can evolve to be more flexible, and that running production nodes in noop mode with controls may be preferable to fully enforcing on all nodes.
Applying Roles and Profiles method to compliance code
This document discusses adapting the roles and profiles design pattern to writing compliance code in Puppet modules. It begins by noting the challenges of writing compliance code, such as it touching many parts of nodes and leading to sprawling code. It then provides an overview of the roles and profiles pattern, which uses simple "front-end" roles/interfaces and more complex "back-end" profiles/implementations. The rest of the document discusses how to apply this pattern when authoring Puppet modules for compliance - including creating interface and implementation classes, using Hiera for configuration, and tools for reducing boilerplate code. It aims to provide a maintainable structure and simplify adapting to new compliance frameworks or requirements.
KGI compliance as-code approach
This document discusses Kinney Group's Puppet compliance framework for automating STIG compliance and reporting. It notes that customers often implement compliance Puppet code poorly or lack appropriate Puppet knowledge. The framework aims to standardize compliance modules that are data-driven and customizable. It addresses challenges like conflicting modules and keeping compliance current after implementation. The framework generates automated STIG checklists and plans future integration with Puppet Enterprise and Splunk for continued compliance reporting. Kinney Group cites practical experience implementing the framework for various military and government customers.
Enforce compliance policy with model-driven automation
This document discusses model-driven automation for enforcing compliance. It begins with an overview of compliance benchmarks and the CIS benchmarks. It then discusses implementing benchmarks, common challenges around configuration drift and lack of visibility, and how to define compliance policy as code. The key points are that automation is essential for compliance at scale; a model-driven approach defines how a system should be configured and uses desired-state enforcement to keep systems compliant; and defining compliance policy as code, managing it with source control, and automating it with CI/CD helps achieve continuous compliance.
Keynote: Puppet camp compliance
This document discusses how organizations can move from a reactive approach to compliance to a proactive approach using automation. It notes that over 50% of CIOs cite security and compliance as a barrier to IT modernization. Puppet offers an end-to-end compliance solution that allows organizations to automatically eliminate configuration drift, enforce compliance at scale across operating systems and environments, and define policy as code. The solution helps organizations improve compliance from 50% to over 90% compliant. The document argues that taking a proactive automation approach to compliance can turn it into a competitive advantage by improving speed and innovation.
Automating it management with Puppet + ServiceNow
As the leading IT Service Management and IT Operations Management platform in the marketplace, ServiceNow is used by many organizations to address everything from self service IT requests to Change, Incident and Problem Management. The strength of the platform is in the workflows and processes that are built around the shared data model, represented in the CMDB. This provides the ‘single source of truth’ for the organization.
Puppet Enterprise is a leading automation platform focused on the IT Configuration Management and Compliance space. Puppet Enterprise has a unique perspective on the state of systems being managed, constantly being updated and kept accurate as part of the regular Puppet operation. Puppet Enterprise is the automation engine ensuring that the environment stays consistent and in compliance.
In this webinar, we will explore how to maximize the value of both solutions, with Puppet Enterprise automating the actions required to drive a change, and ServiceNow governing the process around that change, from definition to approval. We will introduce and demonstrate several published integration points between the two solutions, in the areas of Self-Service Infrastructure, Enriched Change Management and Automated Incident Registration.

The Dynamic Duo of Puppet and Vault tame SSL Certificates, Nick Maludy
The document discusses using Puppet and Vault together to dynamically manage SSL certificates. Puppet can use the vault_cert resource to request signed certificates from Vault and configure services to use the certificates. On Windows, some additional logic is needed to retrieve certificates' thumbprints and bind services to certificates using those thumbprints. This approach provides automated certificate renewal and distribution across platforms.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

For the full video of this presentation, please visit: https://www.edge-ai-vision.com/2024/06/how-axelera-ai-uses-digital-compute-in-memory-to-deliver-fast-and-energy-efficient-computer-vision-a-presentation-from-axelera-ai/
Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
