Eric grover strategies for sharing code with windows 8 and windows phone 8 ...
The document discusses strategies for sharing code between Windows Store and Windows Phone apps. It recommends using a Portable Class Library (PCL) to share models, core view models, business logic, data services, and other generic logic. Linked files can be used to share converters, common platform implementations, and static assets. Where platform APIs differ slightly, compiler directives allow conditional compilation. Platform-specific code like navigation and local storage access can be abstracted using base classes and interfaces. Localization strings can potentially be shared by modifying the PCL project file, but the process is not straightforward.

Ekon23 (1) Kingdom-Driven-Design
After years working on Domain-Driven Design projects using Delphi for server-side processes, I eventually followed some kind of cut-back version of the DDD paradigms. Introducing Kingdom Driven Design (aka KDD) – since in biology “Kingdom” is the second highest taxonomic rank, just after “Domain”. We will present some principles to help writing not-database-centric code, without being bloated by all the DDD requirements.
Let your Kingdom come!
Domain driven design simplified
This document discusses the principles of Domain Driven Design (DDD). It explains that a domain and subdomains fall under the problem space in DDD. A bounded context and context map fall under the solution space. A bounded context defines a semantic boundary and uses a ubiquitous language that is specific to that context. Core domains are most important to a business's success. Context mapping shows how bounded contexts integrate and communicate with patterns like shared kernel, customer-supplier, and published language. The document provides an example of applying DDD to refactor a "big ball of mud" project into separate bounded contexts. It also explains DDD tactical patterns like entities, aggregates, value objects and ensuring transactional consistency within aggregates.
2011 iska - tim m - domain driven design
Domain Driven Design (DDD) is an approach to software development that prioritizes domain knowledge. It focuses on building a shared understanding between technical and domain experts through a ubiquitous language. The fundamentals of DDD include modeling the domain, domain objects like entities and value objects, aggregates, repositories, and bounded contexts. Patterns like modules, factories, and specifications help implement the domain model. The goal is clean, knowledge-rich design focused on the business domain.

This document discusses using Function Point Analysis (FPA) as a metric for Agile software projects. It provides context on replacing an existing trading system and outlines an architecture and development approach using Agile/Scrum. Metrics are proposed for use at the sprint level and cumulatively, including function points, story points, lines of code, and productivity rates. FPA is argued to provide benefits for scope management, benchmarking, and proving productivity and quality for Agile projects. Contracting based on function points is also discussed.
A Software Factory Integrating Rational & WebSphere Tools
The document discusses how a large automotive retailer integrated Rational Software Architect, WebSphere Message Broker, and Rational Team Concert into a software factory to develop an integration layer between a new point of sale system and SAP backend. Key challenges included a multi-vendor global team and parallel development of UI, integration, and backend layers. The software factory employed model-driven development, continuous integration, and practices like architectural modeling in UML, automated WSDL generation, tracking work items and impediments, and collaborative configuration management to help coordinate distributed development and integrate results.

Microservice Teams - How the cloud changes the way we work
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.

Graspan: A Big Data System for Big Code Analysis
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
- Accepted in ASPLOS ‘17, Xi’an, China.
- Featured in the tutorial, Systemized Program Analyses: A Big Data Perspective on Static Analysis Scalability, ASPLOS ‘17.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
