Sioux Hot-or-Not: Essential Unified Process (Ivar Jacobson)siouxhotornot
The document discusses the need for a new paradigm in software development processes that focuses on practices rather than predefined processes. It argues that processes should be composed of lightweight, independently applicable practices from different methodologies. This allows teams to select the practices most suitable for their needs and change practices flexibly over time. The Essential Unified Process is presented as an example of a practice-centric process delivered through practices rather than rigid methodologies.
This document provides an introduction to model driven engineering and software models. It discusses how models provide an abstract representation of a system that can be used to investigate and verify properties before production. The document then covers the history of software models and milestones like the Object Management Group adopting standards like the Unified Modeling Language (UML) and Model Driven Architecture (MDA). It defines key concepts in model driven engineering like platform independent models and platform specific models. Finally, it discusses how models are specified using meta-models and transformations between models.

Chapter 10 - http://www.slideshare.net/jcabot/mdse-bookslideschapter10managingmodels
This book discusses how approaches based on modeling can improve the daily practice of software professionals. This is known as Model-Driven Software Engineering (MDSE) or, simply, Model-Driven Engineering (MDE).
MDSE practices have proved to increase efficiency and effectiveness in software development. MDSE adoption in the software industry is foreseen to grow exponentially in the near future, e.g., due to the convergence of software development and business analysis.
This book is an agile and flexible tool to introduce you to the MDE and MDSE world, thus allowing you to quickly understand its basic principles and techniques and to choose the right set of MDE instruments for your needs so that you can start to benefit from MDE right away.
The first part discusses the foundations of MDSE in terms of basic concepts (i.e., models and transformations), driving principles, application scenarios and current standards, like the wellknown MDA initiative proposed by OMG (Object Management Group) as well as the practices on how to integrate MDE in existing development processes.
The second part deals with the technical aspects of MDSE, spanning from the basics on when and how to build a domain-specific modeling language, to the description of Model-to-Text and Model-to-Model transformations, and the tools that support the management of MDE projects.
The book covers introductory and technical topics, spanning definitions and orientation in the MD* world, metamodeling, domain specific languages, model transformations, reverse engineering, OMG's MDA, UML, OCL, ATL, QVT, MOF, Eclipse, EMF, GMF, TCS, xText.

The document discusses the role of the modern software architect. It provides definitions of a software architect as someone who makes high-level design choices and dictates technical standards. The main responsibilities of an architect are to limit development choices by choosing standards and frameworks and communicating designs to developers. The document also discusses how the role of the architect changes with the size of the organization and types of architectures like enterprise, solution, and application architects. It notes challenges with more agile development where architecture may not receive focus and issues like technical debt can increase over time.
Simon Brown: Software Architecture as Code at I T.A.K.E. Unconference 2015Mozaic Works
This document discusses software architecture and how it relates to code. It suggests that software architecture should be more accessible to developers and embodied in the code through architecturally evident coding styles. Components can be extracted from code if naming conventions, packaging, and other patterns are used. Both diagrams and code should reflect the architectural abstractions. Software architecture models can be maintained as code to keep them in sync with implementation changes.
This document discusses various architectural styles including data-centered, data-flow, call and return, layered, and client-server architectures. It explains how to map a data flow diagram (DFD) showing transform or transaction flows to a call and return architecture. Examples are provided of mapping transform and transaction flows from DFDs to the corresponding call and return architecture. Homework tasks are assigned to map DFDs for course registration and temperature monitoring systems to a call and return architecture.
Basics of Software Architecture for .NET DevelopersDan Douglas
The document discusses the basics of software architecture for .NET developers. It defines software architecture as the structure and design of an application, including its components and how they are connected. A good architecture provides advantages like compatibility, extensibility, reliability and maintainability. The software architect must take implicit requirements into account, such as scaling and future needs, even if stakeholders are not aware of them. Architects should understand object oriented principles, design patterns, emerging technologies and focus on reusability.
This document provides an overview of software architectures by presenting examples of architectures from various software systems. It begins with an introduction to software architecture and what it entails. It then shows numerous diagrams and visualizations of architectures for different types of systems, such as editors, compilers, operating systems, middleware, and web applications. These examples are intended to demonstrate common architectural patterns and styles. The document discusses analyzing and comparing the architectures visually and recognizing patterns within them.
Model Driven Architecture (MDA) is an approach proposed by the Object Management Group to address challenges of business and technology change by separating business logic and system specifications from implementation details using model-driven engineering. MDA uses standards like UML, MOF, and XMI to transform platform-independent models into specific platforms through automated transformations. Adopting MDA promises benefits like increased portability, interoperability, and adaptability of systems while reducing costs and shortening development times.
This document discusses software design principles and methods. It covers topics like abstraction, modularity, coupling and cohesion, and information hiding. It also describes different design methods including functional decomposition, data flow design, design based on data structures, and object-oriented design. Key aspects of these methods are explained, such as the stages of object-oriented analysis and design. The document provides examples to illustrate different design concepts and metrics.
This document discusses Model Driven Architecture (MDA), an approach to software development promoted by the Object Management Group (OMG) that uses abstract models to promote portability, interoperability, and reuse of assets. It defines key MDA concepts like platform independent models (PIM), platform specific models (PSM), and the OMG's four-layer meta-modeling architecture. The document also examines modeling languages like UML and COSEML that can be used at the PIM layer and how MDA aims to reduce costs and improve quality through model-based development and code generation from models.
2013 Good Design Is Good Business MDD Embedded SystemsRoger Snook
Agenda:
1. Code in the world of model-driven development (MDD)
2. Using model-driven development to accelerate traditional development
3. MDD capabilities and technologies for code centric development
The document discusses using model-driven architectures and code generators to increase efficiency in software development. It proposes generating code from models and databases to avoid duplicative work. This allows focusing on domain-specific architectures and knowledge work rather than repetitive coding. Examples of code generators like MyGeneration and CodeSmith Studio are provided.
The document introduces model-driven software development (MDSD) and provides examples to illustrate key concepts. MDSD uses models as primary artifacts in the development process which are transformed to executable code. Models conform to metamodels and can be transformed through one or more steps. Examples show models of components, workflows, and a power grid, along with their corresponding metamodels. MDSD aims to increase reuse, separate domain expertise from technical concerns, and make the development process more efficient.
- Yogesh Kadam is a software developer with over 5 years of experience working in Java. He currently lives and works in Dresden, Germany.
- He has a Bachelor's degree in Engineering and is proficient in languages like Java, frameworks like Spring and databases like Oracle.
- His work experience includes projects for companies like Daimler and Motorola where he served as team lead and developed modules using technologies like Java, Hibernate and Struts.
The document discusses key design concepts and principles for software design. It explains that the goal of design is to meet requirements while being readable, understandable, and providing a complete picture of the software. Good design exhibits modularity, appropriate data structures, distinct representations, and interfaces that reduce complexity. Design principles include considering alternatives, traceability to analysis, reuse, minimizing abstraction, and accommodating change. Abstraction and refinement aid in creating a complete design, while modularity makes large problems more manageable by breaking them into smaller pieces. Modularity is balanced by finding the optimal module size and granularity.
The document discusses different methods for component level design:
1. There are three main types of component level design methods: graphical design notation using flowcharts, tabular design notation using decision tables, and program design language using pseudo-code.
2. Flowcharts use sequence, if-then-else, and repetition constructs. Decision tables map conditions to corresponding actions.
3. Pseudo-code describes programming tasks in plain English without strict syntax. It depends on the designer's style.
In the last two decades, refactoring for code and design smells have received considerable focus from both academia and industry. This talk covers large scale refactoring for architectural smells which is gaining considerable attention from the software engineering community in the last few years. The main focus is on real-world case-studies and experiences in performing large scale refactoring for architectural smells from both industrial and open source projects. This talk will provide useful pointers to the participants on how to deal with refactoring for architectural smells in real-world contexts; further, it will also suggest research questions for the software engineering community to explore.

This document provides an overview of software design engineering concepts in 3 sentences or less:
The document outlines the key concepts in software design including the design process, design quality, abstraction, architecture, patterns, modularity, information hiding, and functional independence. It also summarizes design models, principles of data design, architectural styles like layered architectures, and common architectural patterns for concurrency, persistence, and distribution.
The document discusses key concepts in software architecture, including:
1) Software architecture establishes the overall structure and organization of a system, including its components and relationships.
2) Architectural design involves decomposing a system into subsystems or modules to improve modifiability, reusability, and portability.
3) Key principles for architectural design include simplicity, modularity, low coupling, separation of concerns, abstraction, and postponing decisions.
The document discusses key concepts and principles of software design. It explains that design involves two major phases - diversification, where alternative solutions are considered, and convergence, where elements are chosen and combined to meet requirements. Good design principles include modularity, information hiding, and functional independence. The goal of design is to produce models and specifications that can be implemented to meet a customer's needs.
The document discusses the results of a recent Progress client survey on database vendors and technologies. It hints that the winners of Apache, MariaDB, and MongoDB will be revealed, as well as the preferred database vendor for the future based on responses from a global customer base. Readers are encouraged to review the unbiased survey results to empower their company.
The document discusses Lewis diagrams and the octet rule for drawing molecular structures. It notes that most atoms form bonds to gain eight valence electrons, with exceptions for hydrogen, groups 1-3, and atoms that can exceed eight electrons. It provides instructions for drawing Lewis diagrams: determine total valence electrons, arrange atoms with singular in middle, form bonds between atoms, and distribute remaining electrons to give each atom an octet where possible. Examples of drawing Lewis diagrams for CF4, BeCl2, and CO2 are included to demonstrate the process.

Factors influencing popularity of branded content in Facebook fan pagesToni Cañabate
Social media is achieving an increasing importance as a channel for gathering information about products and services. Brands are developing its presence in social networking sites to meet brand awareness, engagement and word of mouth. In this context, the analysis of the factors that are conditioning consumer interaction with branded content becomes a matter of interest. These slides introduce a research work that aims to shed light on those factors that are expected to impact on Facebook branded post popularity. Results suggest that the richness of the content (inclusions of images and videos) raises the impact of the post in terms of likes. On the other hand, using images and a proper publication time are significantly influencing the number of comments, whereas the use of links may decrease this metric.

3) A 2005-2007 Europe-wide study found internet health users increased from 44% to 54%. The growth occurred across all countries. The internet will be important for future healthcare.
Thomas Paine was an English-American political activist and philosopher. He was born in 1737 in England and died in 1809 in New York City. Paine is known for writing influential pamphlets and papers that advocated for American independence and challenged institutionalized religion. Some of his most notable works include Common Sense, published in 1776, which was instrumental in promoting revolutionary ideas in the American colonies. Paine also wrote The Age of Reason and Rights of Man, which criticized institutionalized religion and advocated for liberalism and republicanism. He influenced many American and French revolutionaries with his writings and political ideas.

Reference Scope Identification in Citing SentencesAkihiro Kameda
This document describes an approach to identify the scope of references in sentences containing multiple citations. The approach uses a conditional random field (CRF) sequence model with features including distance, position, part-of-speech tags, and syntactic dependencies. It first segments sentences using punctuation and conjunctions, then applies the CRF and a majority voting scheme to label each word as inside or outside the scope. The method achieved over 90% accuracy on a dataset of citations from ACL papers.

Banner and Bursar: A match made ... somewhere?F. Tracy Farmer
The document describes the process of transferring library fines and fees from the library system, Voyager, to the university's ERP system, Banner. Initially, the library used the Bursar Transfer System alone but the data it produced was not acceptable. Over time, custom code was developed to reduce the data into a simpler format of patron ID, finance code, term code, and amount. The code also combines charges for the same patron into one line and adds a summary line. The new charge file is then transferred between systems to import the fines and fees into patron accounts.
The document contains review questions about momentum, impulse, and the conservation of momentum. It asks about the equations for momentum and impulse, examples of their application like a bird's momentum and a truck's runaway ramp, and problems involving conservation of momentum such as a fish swallowing another fish or a person jumping out of a moving golf cart. It also questions the differences between elastic and inelastic collisions, and how impulse relates to safely catching or stopping moving objects without damage.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
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).

TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
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.

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?
