• Support for .NET Core 2.0: you can now edit, run, debug, test, navigate and refactor your shiny new .NET Core applications.
  
• Rider 2017.2 comes with ReSharper 2017.2 as its engine for providing .NET support. This means a number of features announced with ReSharper 2017.2 are now available in Rider. 

With a great pleasure and great relief OpenCV team finally announces OpenCV 3.0 gold release, the most functional and the fastest OpenCV ever. And yet it’s very stable too – all the thousands of tests that we created during the project + many new tests pass successfully on Windows, Linux and Mac, x64 and ARM.

In this episode, Robert is joined by Phil Japikse for a chat about design patterns. Software design patterns have been around long before the MVC Framework gained momentum. Phil starts with a review of Robert C. Martin's (Uncle Bob) SOLID macronym. After building the proper foundation,he reviews several design patterns, their C# implementation and when and how they should be used in modern software development. 

• شاید امروز معنای یک کد را متوجه شوید، ولی آیا در آینده، مثلا یک سال بعد هم چنین خواهد بود؟
  
•  آیا می‌توانید هر سیستمی را که طراحی می‌کنید، به خاطر بسپارید که فعالیت‌هایش را به چه نحوی انجام می‌دهد؟
  
• اگر در یک کار تیمی باشید، شاید شما متوجه کدتان می‌شوید، ولی آیا تضمینی وجود دارد که دیگران هم متوجه روش شما شوند؟
  
• آیا کدی که شما بر روی آن فکر کرده‌اید و در ذهن خود روش انجام آن را ترسیم کرده‌اید، می‌تواند برای برنامه نویسی که کد شما را می‌بیند هم رخ دهد؟ 
  
• اگر شما به صورت تیمی کاری را انجام دهید و یکی از برنامه نویس‌های شما از تیم جدا شود، چگونه می‌توانید کار او را دنبال کنید؟
• اگر برای برنامه نویسی اتفاق یا حادثه‌ای پیش بیاید که دسترسی شما به او ممکن نباشد چه؟
  

PCMBOAT5.PAS*************************************************************
**
File: PCMBOAT5.PAS
Author: B. Spuida
Date: 1.5.1999
Revision: 
1.1 
PCM-DAS08 and -16S/12 are supported.
Sorting routine inserted.
Set-files are read in and card as well as
amplification factor are parsed.

1.1.1
Standard deviation is calculated.

1.1.2
Median is output. Modal value is output.

1.1.4
Sign in Set-file is evaluated.
Individual values are no longer output.
(For tests with raw data use PCMRAW.EXE)

To do:
outliers routine to be revised.
Statistics routines need reworking.
Existing Datafile is backed up.

Purpose: 
Used for measurement of profiles using the
Water-SP-probes using the amplifier andthe PCM-DAS08-card, values are acquired
with n = 3000. Measurements are taken in 1
second intervals. The values are sorted using
Quicksort and are stacked "raw" as well as after
dismissing the highest and lowest 200 values as
'outliers'.


Requirements:
The Card must have an A/D-converter.
Amplifier and probes must be connected.
Analog Signal must be present.
CB.CFG must be in the directory specified by the
env-Variable "CBDIREC" or in present directory.

dotnet-format is a code formatter for dotnet that applies style preferences to a project or solution. Preferences will be read from an .editorconfig file, if present, otherwise a default set of preferences will be used. 

We are extremely excited to announce the general availability of EF Core 3.0and EF 6.3 on  nuget.org . 

What’s new in EF Core 3.0

Including major features, minor enhancements, and bug fixes, EF Core 3.0 contains more than 600 product improvements. Here are some of the most important ones:

•  LINQ overhaul
•  Restricted client evaluation
•  Single SQL statement per LINQ query
•  Cosmos DB support
•  C# 8.0 support (Asynchronous streams, Nullable reference types)
•  Interception of database operations
•  Reverse engineering of database views
•  Dependent entities sharing a table with principal are now optional

AutoMapper 8.1 adds a major new feature - attribute-based maps. Attribute maps let you easily declare maps on destination types when you have straightforward scenarios. Instead of: 

public class OrderProfile {  
    public OrderProfile() {
        CreateMap<Order, OrderIndexModel>();
        CreateMap<Order, OrderEditModel>();
        CreateMap<Order, OrderCreateModel>();
    }
}

You can declare your type maps directly on the destination types themselves with AutoMapAttribute: 

[AutoMap(typeof(Order))]
public class OrderIndexModel {  
    // members
}

[AutoMap(typeof(Order))]
public class OrderEditModel {  
    // members
}

[AutoMap(typeof(Order))]
public class OrderCreateModel {  
    // members
}

The fourth preview of .NET 7 includes enhancements to observability in the .NET implementation of OpenTelemetry, the addition of properties to track microseconds and nanoseconds in date and time structures, new metrics for caching extensions, performance-boosting “on stack replacement,” APIs to work with .tar archives, and additional features as part of an ongoing effort to improve the performance of and add features to regular expressions in .NET 7.  

Microservices are groupings of lightweight services, interconnected, although independent of each other, without direct coupling or dependency.
