A (very) opinionated guide to MSBuild and Project FilesDavid Wengier
This document discusses project files and MSBuild. It explains that project files are MSBuild files that define properties, items, imports and targets. It compares legacy project files to SDK-style project files. It also discusses how MSBuild works by parsing the project file and evaluating properties, items, imports and targets. Finally, it recommends using build logging to see how MSBuild evaluates the project file.
Data Loading Made Easy with Mike Nakhimovich DroidCon Italy 2017Mike Nakhimovich
The document discusses data loading and how the NY Times built the Store library to simplify it. Some key points:
- Store manages fetching, parsing, and caching of data for a specific model. It handles all the data flow in a reactive and persistent way.
- Stores are Observable objects that provide methods like get(), fetch(), and stream() to interact with data.
- The Store library uses repositories, parsers, and persisters to abstract where data comes from and how it's stored, cached, and transformed.
- Stores help achieve goals like surviving configuration changes, reducing memory usage, and standardizing offline behavior. They make data loading asynchronous, reactive, and dependent calls easier.
The document summarizes the New York Times' open source Store library for Android, which provides a unified way to fetch, parse, cache, and retrieve data in Android applications. The Store abstracts these processes and enforces unidirectional data flow while exposing data as RxJava Observables. Key aspects include using StoreBuilders to configure Stores, adding fetchers and parsers, using middleware like GsonSourceParser, and enabling disk caching. The document also provides guidance on open sourcing a new library, including using Android Studio and GitHub to set up the project, adding documentation like README and license, and publishing to Maven Central.

- The document discusses creating an Android Studio plugin to generate CreateIntent methods for passing data between activities.
- It provides examples of how code generator plugins work by modifying the code in the current file based on the cursor position. The plugin would generate the CreateIntent method code based on the fields in the class.
- The key aspects of creating such a plugin involve using the Android Studio API to access the current file and class, generate the method code as a PsiElement, and insert it into the class. This allows automatically generating boilerplate code to reduce errors and effort.
“Program to an interface, not an implementation” they[1] say …
But when IMyInterface foo = new IMyInterface() is not valid code … how are you supposed to achieve that ? The answer is Dependency Injection.
In this talk, we’ll talk about Dependency injection, what it is and what it is not. We’ll see how it is a valuable set of practices and patterns that help design maintainable software built on top of the SOLID object-oriented principles.
We’ll see how, when used properly, it delivers many benefits such as extensibility and testability … We’ll also cover some anti-patterns, ways of using Dependency Injection that can lead to code that is painful to understand and maintain
This talk is not about DI/IOC containers per se, but focuses on the core concepts of Dependency Injection. Those concepts are essential to understand how to use those “magic-looking” tools (if they are needed at all …)
This talk is not only for .NET developers. It will contain code examples written in C#, but should be understandable by developers with knowledge in other statically-typed object-oriented languages such as Java, Vb.NET, C++ …

This document describes a library management system that includes both Windows and web-based interfaces. It aims to handle common library functions with minimal training while maintaining easily maintained and validated code. Code samples demonstrate validation of member information and error handling. Sections also describe the main interface, forms for checking in/out items and adding members, and how juvenile members are promoted to adults.
Unit testing patterns for concurrent codeDror Helper
Getting started with unit testing is not hard, the only problem is that most programs are more than a simple calculator with two parameters and a returns value that is easy to verify. Writing unit tests for multi-threaded code is harder still. Over the years I discovered useful patterns that helped me to test multi-threaded and asynchronous code and enabled the creation of deterministic, simple and robust unit tests. Come learn how to test code that uses concurrency and parallelism – so that the excuses of not writing unit tests for such code would become as obsolete as a single core processors.
Demostración del paso a paso para conectarse a los datos de una lista de SharePoint utilizando llamadas a la API desde una WebPart de SharePoint Framework, realizando las tareas de Creación, Actualización, Eliminación y Consulta de Datos.
Using the SharePoint Framework as a surface to express yourself through client side solutions is great but at some point in time, you will require that this beauty you built interacts with APIs holding data that lives within the Office 365 environment. In this session, you will learn how to utilize and optimize your calls to SharePoint via its REST APIs, to the Microsoft Graph and to external services that you might find useful to deliver a rich experience in your solution. You will also learn about how to simplify those calls using the Community-Driven library PnP JS Core that aims to save your time (and sanity) by simplifying the access to the SharePoint REST APIs and to the Microsoft Graph. Goodbye URLs, hello intellisense!

Agile methodologies based on BDD and CI by Nikolai ShevchenkoMoldova ICT Summit
BDD is an agile methodology that focuses on describing an application from stakeholders' perspectives using scenarios written in a common language like Gherkin. It revolves around user stories made up of scenarios and executable steps. This ensures collaboration between business analysts, QA teams, and developers. CI integrates source code and runs tests after each commit for near-immediate feedback to catch errors early. BDD and CI provide benefits like lower barriers to entry, greater ROI, and predictability through automated tests that validate business needs are met.
This document summarizes the new features of JPA 2.0 as defined in JSR 317. Key additions include expanded object-relational mappings, improved domain modeling capabilities, enhancements to the Java Persistence query language including a Criteria API, standardization of configuration hints, support for validation via JSR 303, and second level caching.
Most frameworks such as ASP.NET or SignalR configures the data protection system and sum it to a service container you approach via dependency injection. The following sample explains configuring a service container for dependency injection and listing the data protection stack, receiving the data protection provider via DI, developing a protector and protecting the unprotected data
The document discusses upcoming features in Java EE 8 including enhancements to support HTML5, JSON processing, model-view-controller (MVC) architecture, and HTTP/2. Key areas of focus are improved JSON binding and processing APIs, support for server-sent events, an action-based MVC specification, and integration of HTTP/2 features in technologies like Servlet. The presentation also covers goals of easing development and enabling Java EE applications to better run in the cloud.
This document provides an overview of REST (Representational State Transfer), including the key aspects of RESTful architectures such as:
- Resources are addressed through URIs
- Standard HTTP methods like GET, PUT, POST, DELETE are used to manipulate resources
- Data is represented in various formats like JSON, XML, HTML
- Communication is stateless between client and server
It then discusses how these REST principles are implemented in RESTEasy, the JBoss RESTful Web Services framework, through annotations and APIs. Features like content negotiation, interceptors, asynchronous calls and caching are also covered.
Vaadin DevDay 2017 - Data Binding in Vaadin 8Peter Lehto
The document discusses improving editing of customer records in Vaadin 7 applications. It outlines issues with directly using setters and listeners on each field, such as lots of code, implicit saving, and difficulty validating values. It recommends using a FieldGroup to bind fields to properties, which avoids explicit setters, allows committing or discarding changes, and integrates validation into the commit process. However, it notes there may still be room for improvement over the Vaadin 7 approach.
RESTEasy is a framework for building RESTful web services in Java. It allows developers to write JAX-RS annotated Java classes to define resources and their representations. Resources are addressable via URIs and support standard HTTP methods like GET, PUT, POST, and DELETE. Resources return representations in formats like JSON, XML, and HTML. Communication is stateless and driven by hypermedia links between resources. RESTEasy supports features like interceptors, asynchronous jobs, caching, GZIP compression, and integration with Spring and other frameworks.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
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.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
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.

21. “ Even though developers follow TDD principle, without design
principles and patterns in the first place, software testing is still a
challenge task. This brings us into the search of design pattern which
eases software testing in general. One of the design patterns, which
associates with software testing, is Dependency Injection.
Dependency injection is claimed to increase testability of software
because by following the dependency injection pattern, external
resources such as database and web service can be mocked or faked
to allow testing software components in isolation from one another. ”
32. So why exactly does it happen? What makes tests brittle?
The reason is mocks.
Test suites with a large number of mocked dependencies require a lot of maintenance.

as your code base evolves.
Did you notice that, in order to make your code testable, you need to mess it up first?
And the tests look like a big ball of mud that is hard to understand and maintain?
Unit Tests report too many false positives
