Benchmarking .NET libraries for image resizing: which performs best?
Which .NET library is fastest at image resizing? Which one uses the least memory? A benchmark comparison of ImageSharp, Magick.NET, NetVips, and SkiaSharp.
D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS. D3’s emphasis on web standards gives you the full capabilities of modern
I love Entity Framework. I also like (not love) nHibernate. That’s right, as a DBA and data professional, I’m telling you I love Object/Relational Mapping tools (ORM). I think this is a technology set that the DBA needs to more tightly embrace. Let me tell you why.
Moq is a mocking library for .NET Unit Testing (cue the TDD folks reminding us mocks are unnecessary), and it is by far the most widely used mocking library in .NET (475 million downloads vs 87 million for the next largest, NSubstitute). Yesterday, its author released version 4.20.1; which added nagware and a backdoor to Moq, in a bid to drive up paid usages of Moq through ‘Sponsorships’.
:When to use Async/Await
There are basically two scenarios where Async/Await is the right solution
I/O-bound work: Your code will be waiting for something, such as data from a database, reading a file, a call to a web service. In this case you should use Async/Await, but not use the .Task Parallel Library
CPU-bound work: Your code will be performing a complex computation. In this case, you should use Async/Await but spawn the work off on another thread using Task.Run. You may .also consider using the Task Parallel Library
In short, domain events help you to express, explicitly, the domain rules, based in the ubiquitous language provided by the domain experts. Domain events also enable a better separation of concerns among classes within the same domain.
It's important to ensure that, just like a database transaction, either all the operations related to a domain event finish successfully or none of them do.
Domain events are similar to messaging-style events, with one important difference. With real messaging, message queuing, message brokers, or a service bus using AMQP, a message is always sent asynchronously and communicated across processes and machines. This is useful for integrating multiple Bounded Contexts, microservices, or even different applications. However, with domain events, you want to raise an event from the domain operation you are currently running, but you want any side effects to occur within the same domain.
The domain events and their side effects (the actions triggered afterwards that are managed by event handlers) should occur almost immediately, usually in-process, and within the same domain. Thus, domain events could be synchronous or asynchronous. Integration events, however, should always be asynchronous.
