Doi MVP si doua prezentari despre Xamarin , Machine Learning si Azure

Prezentare 1:

Titlu : Cross-platform mobile application with Xamarin and Integration with Azure DevOps`

Descriere: Just a few clicks and you will have your app up and running inside out favorite DevOps Tool. You can create your dedicated Xamarin pipeline from the portal. Join me to find out more!

Speaker: Codrina Merigo , https://mvp.microsoft.com/en-us/PublicProfile/5003771?fullName=Codrina%20Merigo

 

Prezentare 2:

Titlu:
Deploying a Machine Learning Model with Azure ML Pipelines

Descriere:
Azure Machine Learning pipelines are independently executable workflows of complete machine learning tasks. They are extremely flexible, and can be used for a large variety of scenarios, from simple offline scoring scenarios, to complex deep learning architectures.

During this talk Vlad will discuss the difference between online and offline scoring, the need for applying solid development principles such as SOLID in machine learning, and how pipelines help in that regard.

He will also show how to create a pipeline for deploying and running a simple model, and discuss possibilities for improvement.

Speaker: Vlad Iliescu, https://vladiliescu.net/

RSCG – Curry – Partial function – part 12

 

 

name PartiallyApplied
nuget

https://www.nuget.org/packages/PartiallyApplied/

author Andrei Ignat

This will generate curry for your functions
 

The code that you start with is


    public class Accounting                                            

    {

        public static float Discount( float discount, float price)

        {

            var val= price * (1- discount);

            return val;

        }

    }


The code that you will use is



    var disc10Percent = Partially.Apply(Accounting.Discount, 1/10f);

    Console.WriteLine(disc10Percent(disc10Percent(100)));

 

The code that is generated is


    public static partial class Partially

    {

           public static Func<float, float> Apply(Func<float, float, float> method, float discount) =>

                  new((price) => method(discount, price));

    }

This will generate code to decorate methods with anything you want ( stopwatch, logging , authorization…)
 

The code that you start with is


    [AutoMethods(template =TemplateMethod.CustomTemplateFile,MethodPrefix ="prv" ,CustomTemplateFileName ="MethodDecorator.txt")]

    public partial class Person

    {

         public string FirstName{ get; set; }

         public string LastName { get; set; }

    

         private string prvFullName()

         {

              return FirstName + " " + LastName;

         }

    }


The code that you will use is



    var p = new Person();                 

    p.FirstName = "Andrei";

    p.LastName = "Ignat";

    Console.WriteLine(p.FullName());

nuget

author Robin Hermanussen

This will generate Mock classes directly for any interface – with your implementation.
 

The code that you start with is


    public interface IMatOps               

    {

        public int Add(int a, int b);

    

        public int Division(int a, int b);

    }


The code that you will use is



    var mock = (IMatOps)new MatOpsMock

    {

        MockAdd = (a, b) => a+b,

        MockDivision = (a,b)=> a/b

    };

 

The code that is generated is


    public partial class MatOpsMock : global::MatOps.IMatOps                                                                                                           

    {

        /// <summary>

        /// Set this to true, if you want members that don't have a mock implementation

        /// to return a default value instead of throwing an exception.

        public bool ReturnDefaultIfNotMocked { get; set; }

    

        private System.Collections.Generic.List<HistoryEntry> historyEntries = new System.Collections.Generic.List<HistoryEntry>();

                }

                else

                {

                    throw new NotImplementedException("Method 'MockAdd' was called, but no mock implementation was provided");

                }

            }

    

            return MockAdd(a, b);

        }

    

        /// <summary>

        /// Implemented for type global::MatOps.IMatOps (Public, same assembly: False)

        /// </summary>

        public Func<int,int,int>? MockDivision { get; set; }

        public int Division(int a, int b)

        {

            historyEntries.Add(new HistoryEntry("Division", new [] { $"{a}", $"{b}" }));

    

            if (MockDivision == null)

            {

                if (ReturnDefaultIfNotMocked)

                {

                    return default(int);

                }

                else

                {

                    throw new NotImplementedException("Method 'MockDivision' was called, but no mock implementation was provided");

                }

            }

    

            return MockDivision(a, b);

        }

This will generate code to retrieve the values of properties directly, not by reflection
 

The code that you start with is


    [AutoMethods(template = TemplateMethod.CustomTemplateFile, CustomTemplateFileName = "GenerateFromPOCO.txt")]

    public partial class Person

    {

        public string FirstName { get; set; }

        public string LastName { get; set; }

    }


The code that you will use is



    var p = new Person();                                      

    p.FirstName = "Andrei";

    p.LastName = "Ignat";

    var last = p.ValueProperty(Person_EnumProps.LastName);

    var first = p.ValueProperty("FirstName");

    

    Console.WriteLine(last + " "+first);

 

The code that is generated is


    public enum Person_EnumProps{

Implements the Builder Design pattern for any class. Useful , at least, for test projects
 

The code that you start with is
