Domain Driven Design: The Good Parts
The greenfield project started out so promising. Instead of devolving into big ball of mud, the team decided to apply domain-driven design principles. Ubiquitous language, proper boundaries, encapsulation, it all made sense.
But along the way, something went completely and utterly wrong. It started with arguments on the proper way of implementing aggregates and entities. Arguments began over project and folder structure. Someone read a blog post that repositories are evil, and ORMs the devil incarnate. Another read that relational databases are last century, we need to store everything as a stream of events. Then came the actor model and frameworks that sounded like someone clearing their throat. Instead of a nice, clean architecture, the team chased the next new approach without ever actually shipping anything.
Beyond the endless technical arguments it causes, domain-driven design can actually produce great software. We have to look past the hype into the true value of DDD, what it can bring to our organizations and how it can enable us to build quality systems. With the advent of microservices, DDD is more important than ever - but only if we can get to the good parts.

How does a developer find a new tool to add to their stack? There’s no single answer, but most will tell you that technical content is part of that journey. Certainly, documentation is crucial to developer experience. But more often than not, the first piece of content they’ll discover is a helpful resource returned as search results or shared from another dev. Your goal is simple: be that resource.
زبان برنامه نویسی Erlang
زبان Erlang در سال 1986 توسط شرکت Ericson سوئد به منظور استفاده در سرورهای switching تلفن ساخته شد. این زبان توسط تیمی به سرپرستی Joe Armstrong معرفی شد تا بتواند از برنامههای توزیعشده، مقاوم در برابر خطا، بلادرنگ و بیوقفه پشتیبانی کند. بعدها این زبان به شکل متنباز در اختیار عموم قرار گرفت. یکی از روشهای برنامه نویسی که توسط این برنامه میشه ازش استفاده کرد، روش تابعی (Functional Programming) هست. این روش قبلا وجود داشت و مدتی هم از مد افتاد، ولی با اومدن پردازندههای چند هسته ای استفاده از زبانهای برنامه نویسی که میشه با اونها تابعی نوشت از سر گرفته شد و حتی مایکروسافت در سال 2010 زبان برنامه نویسی #F رو معرفی کرد. یکی از قابلیتهای زبانهای تابعی سرعت اجرا شدن کدهای اونها هست که اونها رو از زبانهای امری مثل #C و Java جدا میکنه.
Scala هم یک زبان برنامه نویسی همه منظوره هست که ویژگی هایی رو از زبانهای برنامه نویسی شیء گرا داره و همچنین توسط اون میشه برنامه نویسی تابعی انجام داد. از اون به عنوان جانشینی برای جاوا یاد میکنند چون قابلتهای اضافه بر جاوا رو داره.

Integrating SignalR and Angular
“My browser lost its cookies” has long been one of the most longstanding Support complaints in the history of browsers. Unfortunately, the reason that it has been such a longstanding issue is that it’s not the result of a single problem, and if the problem is intermittent (as it often is), troubleshooting the root cause may be non-trivial.
The first preview of Entity Framework Core (EF Core) 8 is available on NuGet today!
