Overview

Microsoft’s Quantum team is excited to announce the Q# Coding Contest – Winter 2019! In this contest you can put your quantum programming skills to the test, solving quantum computing tasks in Q#. Winners will receive a Microsoft Quantum T-shirt!

Quantum computing is a radically different computing paradigm compared to classical computing. Indeed, it is so different that some tasks that are believed to be classically intractable (such as factoring integers or simulating physical systems) can be performed efficiently on a quantum computer. In 2017 Microsoft introduced the Quantum Development Kit which includes the Q# programming language. Q# can be used with Visual Studio, Visual Studio Code or the command line, on Windows, macOS, and Linux.

Introduction & Recap

In the previous blog post, we learned how to create a second level of drill-down (detail of detail) and how to interact with OData and ODataModel (v2) in order to delete a database record.

What will be covered on this exercise

With Part 5 of this series of blog posts, we will learn how to create a SimpleForm within a Dialog that will allow us to update the information of a Sales Order Item.

Before updating the database order we have to check that everything typed by the user validates our constraints.

• ODataModel: we have already used it to display server-side information about our Business Partner, Sales Order, and Sales Order Items. We’ve also used it to delete a database record. We’re now going to use it to update a record thanks to the submitChanges method or remove what we’ve done with the resetChanges method.
• Expression Binding: an enhancement of the SAPUI5 binding syntax, which allows for providing expressions instead of custom formatter functions
• SimpleForm: a layout that allows users to create a pixel-perfect form

F# Software Foundation has recently announced their new initiative — Applied F# Challenge! We encourage you to participate and send your submissions about F# on Azure through the participation form.

Applied F# Challenge is a new initiative to encourage in-depth educational submissions to reveal more of the interesting, unique, and advanced applications of F#.

If you’re unfamiliar with TypeScript, it’s a language that brings static type-checking to JavaScript so that you can catch issues before you even run your code – or before you even save your file. It also includes the latest JavaScript features from the ECMAScript standard on older browsers and runtimes by compiling those features into a form that they understand. But beyond type-checking and compiling your code, TypeScript also provides tooling in your favorite editor so that you can jump to the definition of any variable, find who’s using a given function, and automate refactorings and fixes to common problems.

We’re excited to announce that Visual Studio 2019 will ship a new version of F# when it releases: F# 4.6!

F# 4.6 is a smaller update to the F# language, making it a “true” point-release. As with previous versions of F#, F# 4.6 was developed entirely via an open RFC (requests for comments) process. The F# community has offered very detailed feedback in discussions for this version of the language. You can view all RFCs that correspond with this release here:

• F# 4.6 RFCs
• FSharp.Core 4.6.0 RFCs

This post will detail the feature set and how to get started.

The C++ Core Guidelines’ Lifetime Profile, which is part of the C++ Core Guidelines, aims to detect lifetime problems, like dangling pointers and references, in C++ code. It uses the type information already present in the source along with some simple contracts between functions to detect defects at compile time with minimal annotation.

Hi. My name is Michael Kapelko. I've been developing software professionally for more than 10 years. Recent years were dedicated to iOS. I develop games and game development tools in my spare time.

Overview

Today I want to share my experience of teaching kids to program. I'm going to discuss the following topics:

• organization of the learning process
• learning plan
• memory game
• development tools
• lessons
• results and plans

Swift 5 for Xcode 10.2 beta

Swift

Apple Swift version 5.0 (swiftlang-1001.0.45.7 clang-1001.0.37.7)
Target: x86_64-apple-darwin18.2.0
ABI version: 0.6

Swift apps no longer include dynamically linked libraries for the Swift standard library and Swift SDK overlays in build variants for devices running iOS 12.2, watchOS 5.2, and tvOS 12.2. As a result, Swift apps can be smaller when deployed for testing using TestFlight, or when thinning an app archive for local development distribution.

Visual Studio 2019 Preview 2 is out! And with it, a couple more C# 8.0 features are ready for you to try. It’s mostly about pattern matching, though I’ll touch on a few other news and changes at the end.

Introduction & Recap

In the previous blog post, we learned how to move our current application into a Master-Detail app displaying Business Partner as a list (master) and its detail information with Sale Orders inside the detail page (detail).

What will be covered on this exercise

With Part 4 of this series of blog posts, we will learn how to create a second drill-down page with information about the Sale Order detail and display a table of Sale Order items.

The most important part of this exercise is to understand how to Delete (part of the CRUD operations) a Sale Order Item of a Sale Order.

• ODataModel: we have already used it to display server-side information about our Business Partner, Order Sale. Now we’re going to use it to display Sale Order Item and delete them from the set. For this purpose, we’re going to use the remove method

This is our main task in this exercise but it’s not the only thing we’ve done in the code. Here’s a list of the things you have to do to get to the final result:

• Add a new route and target in the manifest.json to navigate to the BusinessPartnerSeleOrderItem page
• Listen on the Sale Order click event and navigate to the SaleOrder detail (where we will display sale order detail and sale order items)
• Add a FilterBar to filter the Sale Order Item’s table
• Add a ViewSettingsDialog to sort/group Sale Order Items
• Expand the ToProduct navigation property of a SaleOrderItem entity to display Product information into table’s rows

As 2018 has come to an end, now is the time to look towards the future. We typically look out 6 to 12 months and establish topics we want to work on.

As we go we learn and our assessment of some of the topics listed changes. Thus, we may add or drop topics as we go.

We describe some initiatives as «investigations» which means our goal in the next few months is to better understand the problem and potential solutions before scheduling actual feature work. Once an investigation is done, we will update our plan, either deferring the initiative or committing to it.

As always, we will listen to your feedback and adapt our plans if needed.

Introduction & Recap

In the previous blog post, we learned how to filter, sort and group our table. This is a fundamental aspect of every CRUD application because most of the time users have to deal with hundreds of hundreds of records.

What will be covered on this exercise

With Part 3 of this series of blog posts, we will learn how to create a Master-Detail application leveraging the SplitApp UI control and how correctly configure the app’s manifest to handle routes and targets.

• SplitApp: UI control that allows you to create a Master-Detail application (used as a replacement of the App control)
• Routing: we will configure the manifest.json to correctly handle the routing of the application
• ObjectHeader: control that enables the user to easily identify a specific object. The object header title is the key identifier of the object and additional text and icons can be used to further distinguish it from other objects
• Navigation to a detail view and bind the element context: you will learn how to navigate and open a detail page and bind the current View (of the detail) to a new context
• List: in the master page we will use a list to display BusinessPartner because we will have less space

There are only two hard things in Computer Science: cache invalidation
and naming things.

— Phil Karlton

We, developers, spend more time reading code than writing it. It is important for the code to be readable and clear about its intent.

Below are some advice based on my experience naming things.
