C# 6 introduced several new features to the popular C# language, including null-conditional operators to simplify null checking, the ability to await asynchronous operations in catch and finally blocks, nameof expressions to protect against refactoring bugs, and string interpolation for more readable string formatting. Other additions in C# 6 were auto-property initializers, using static for less verbose access to static members, and collection initializers that allow explicitly setting indexes. While some saw the new features as simply reducing boilerplate code, migrating the compiler to a new platform allowed continued innovation in C#.
Functional programming is a paradigm which concentrates on computing results rather than on performing actions. That is, when you call a function, the only significant effect that the function has is usually to compute a value and return it.

How much performance can you get out of Javascript? - Massimiliano Mantione -...Codemotion
JavaScript started as a slow, interpreted language, but in more than two decades things have changed completely and now we have even game engines running in the browser. What is its maximum theoretical performance, and how can you write code that exploits its full potential? We'll see everything a developer must know to write regular Javascript code that literally rivals C++ code, and learn what WebAssembly adds to this.
Building Services With gRPC, Docker and GoMartin Kess
gRPC is an open-source framework for building language agnostic services and clients. This hands-on session will cover techniques for building, testing and monitoring gRPC services using Docker and Go. During this session you will build a simple gRPC service and client, as well as an HTTP reverse-proxy to allow your service to also receive HTTP traffic.
ReactiveCocoa is an elegant framework that radically changes the way we structure our applications and handle flows of data. However, it's beauty is somewhat marred by Objective-C!
In this talk Colin will cover the basics of ReactiveCocoa and the principles of Functional Reactive Programming. Through simple practical examples he will show how ReactiveCocoa and Swift form a beautiful partnership.

The PVS-Studio team is now actively developing a static analyzer for C# code. The first version is expected by the end of 2015. And for now my task is to write a few articles to attract C# programmers' attention to our tool in advance. I've got an updated installer today, so we can now install PVS-Studio with C#-support enabled and even analyze some source code. Without further hesitation, I decided to scan whichever program I had at hand. This happened to be the Umbraco project. Of course we can't expect too much of the current version of the analyzer, but its functionality has been enough to allow me to write this small article.
The front-end React developer world is all abuzz with the fondness of using and preferring TypeScript over JavaScript. Although it’s not recommended for all types of projects it strongly overcomes many shortcomings of JavaScript and improves over it.
Of complicacy of programming, or won't C# save us?PVS-Studio
Programming is hard. I hope no one would argue that. But the topic of new programming languages, or more exactly, search of a "silver bullet" is always highly popular with software developers. The most "trendy" topic currently is superiority of one programming language over the other. For instance, C# is "cooler" than C++. Although holy wars are not the reason why I'm writing this post, still it is a "sore subject" for me. Oh, come on, C#/lisp/F#/Haskell/... won't let you write a smart application that would interact with the outer world and that's all. All the elegance will disappear as soon as you decide to write some real soft and not a sample "in itself".
The presentation talks about the new keywords and behavior for C# 6.0 in Visual Studio 2015. The features are listed as a comparison between C# 6.0 and C# 5.0.
To assess the quality of PVS-Studio C# diagnostics, we test it on a large number of software projects. Since projects are written by different programmers from different teams and companies, we have to deal with different coding styles, shorthand notations, and simply different language features. In this article, I will give an overview of some of the features offered by the wonderful C# language, as well as the issues that one may run into when writing in this language.
Describe the C#.Net major features. This slide includes C# 5.0, C# 6.0 and C# 7.0. C#.net evolution part 1, that is published previously included the C# 1.0, C# 2.0, C# 3.0 and C# 4.0.

Consequences of using the Copy-Paste method in C++ programming and how to dea...Andrey Karpov
I create the PVS-Studio analyzer detecting errors in source code of C/C++/C++0x software. So I have to review a large amount of source code of various applications where we detected suspicious code fragments with the help of PVS-Studio. I have collected a lot of examples demonstrating that an error occurred because of copying and modifying a code fragment. Of course, it has been known for a long time that using Copy-Paste in programming is a bad thing. But let's try to investigate this problem closely instead of limiting ourselves to just saying "do not copy the code".
This slide covers the basic fundamental to start with RactiveJs, All the Practise links as well as the source and reference links are given in the slide.

I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

C# 6.0
1. C# 6
One of the popular languages c-sharp has evolved over the years, under the guidance of
Anders_Hejlsberg, into a feature rich language that is used on billions of devices world-wide.
Version 6, is the first to be compiled with Roslyn the new compiler as a service. This is
important because unlike in previous versions, that were compiled with C++.
2. Roslyn is actually part of the .Net ecosystem. This will allow everybody to leverage the
compiler and ensure Microsoft can innovate C# at a faster cadence, while at the same time
ensuring more robust grammar parsing.
Null-conditional operators
This has to be the most important new feature and is designed to strengthen defensive
programming. By simply allowing you to write your code naturally while at the same time
providing null checking.
int? length = (users!= null)?users.Length:null;
This can now be re-written as.
int? length = users?.Length;
As you can imagine if require multiple levels of null checking, the code quickly becomes
unreadable.
string postCode = ((user != null) && (user.Address != null))
3. ? user.Address.PostCode : null;
Is now far more succinct.
string postCode = user?.Address?.PostCode
Additional we can perform a null check against a delegate.
if (OnPropertyChanged != null)
{
OnPropertyChanged(this, value);
}
To this.
OnPropertyChanged?(this, value);
4. Await in catch and finally
The Async operator introduced in C# 5 didn't allow for the await keyword use in catch and finally
blocks. Which only forced the developer to implement workarounds to compensate. Now with C# 6
we have this feature and the last hurdle to Async programming has been removed.
Service service = new Service();
try
{
res = await service.OpenAsync(…); // We only had this.
}
catch(Exception e)
{
await LogService.LogAsync(service, e); // We Now have this.
}
finally
{
if (res != null) await service.CloseAsync(); // … and this.
}
5. nameof
Refactoring is good programming and Visual Studio includes refactoring tools, like renaming,
this works looking at parse the code to look too understand how to update the code. However,
consider the following:
public string SomeMethod(string valueOne, int valueTwo)
{
if (valueOne == null)
{
Throw new ArgumentException("the parameter valueOne of SomeMethod
is null");
}
If we now try to rename the SomeMethod or valueOne, visual studio would simple ignore
the message found in the argument exception, leaving this code stale.
However, with the nameof expression, we can rewrite this code to protect against rename
and event validate against spelling errors.
6. public string SomeMethod(string valueOne, int valueTwo)
{
if (valueOne == null)
{
throw new ArgumentException($"the parameter {nameof(valueOne)}
of {nameof(SomeMethod)} is null");
}
Some tools like Resharper do attempt to fix these issue they are not perfect.
7. String interpolation
String.Format is versatile and is preferable to concatenation, but it is little clunky and error prone. In
particular the placeholders {0} must match the arguments supplied separately or an exception is
thrown:
var s = string.format("{0,20} is {1:D3} years old", user.Name, user.Age);
Now becomes.
var s = $"{user.Name,20} is {user.Age:D3} years old";
Whats more you can also not included method call and and even extensions methods.
var s = $"{user.FullName()} is {DisplayAge(user)}";
This will produced more concise, readable and error less prone code.
8. Auto-Property Initializers
Properties have been in C# since the very beginning with a minor tweak. With version 6 we
can now initialize properties with an expression, so this.
public class Custom
{
public DateTime TimeStamp { get; private set; }
public Address address { get; private set; }
public Customer(string first, string last)
{
TimeStamp = DateTime.UtcNow;
Address = new Address();
Address .AddressLineOne=”197 Home Street”;
Address .PostCode = ”XX1 1SS”;
}
}
9. Becomes this.
public class Customer
{
public DateTime TimeStamp { get; } = DateTime.UtcNow;
public Address address { get; } = new Address {
AddressLineOne=”197 Home Street”,
PostCode = ”XX1 1SS”
};
}
10. using static
Previously if you wanted to access static methods you needed to prefix the contain class
which lead to more verbose code
using System;
class Program
{
static void Main()
{
Console.WriteLine(Math.Sqrt(3*3 + 4*4));
Console.WriteLine(DayOfWeek.Friday - DayOfWeek.Monday);
}
}
11. Now with the static using we can reduce this repetitive code too this.
using static System.Console;
using static System.Math;
using static System.DayOfWeek;
class Program
{
static void Main()
{
WriteLine(Sqrt(3*3 + 4*4));
WriteLine(Friday - Monday);
}
}
Like many of the other feature this improves readability, however the possibility namespace
clashes also increases.
12. Index Collection Initializers
We also have a small improvement to initializers, that allow us to explicitly declare that we're
setting an index, so this.
var numbers = new Dictionary<int, string> {
{7, "seven"},
{9 , "nine"},
{13 , "thirteen"}};
Becomes this.
var dict = new Dictionary<string, string> {
[7] = "seven" ,
[9] = "nine",
[13] = "thirteen" };
13. Now while if example above show that we're actually setting an index property, this feature
really shines with objects rather than values.
var customers = new Dictionary<string, Customer> {
["1"] = new Customer("joe","doe"),
["2"] = new Customer("joe","doe")
};
Under the covers all c# is doing is rewriting use the Add methods.
This boilerplate code while not necessary does increase the readability. I addition, C# will
can now resolve extension methods with will be able to allow any collection utilize Initialize rs.
Conclusion
You could be forgiven for thinking Microsoft is running out of idea's and the new feature are
only boiler plate code and that C# is starting to fossilize. While It's true that as programming
language mature, innovating is harder, as the grammar becomes more complex.
The process of migrating a language compiler onto a new platform is a huge undertaking. So
in future release we can expect more innovation to return. Finally, while these feature could
be described as boilerplate I would counter that this is true for high level languages as they
ultimately compile down to Assembly.
