Continuous Delivery with Feature Flags (toggles) is More Difficult Than it Seems
What happens if you’re working on something that lasts much more than one sprint? Maybe 3 sprints or 10. Are you going to work on a separate branch, ending with a huge merge? Are you going to run automated tests on that branch? This matter is not that simple, as I recently experienced.
Pipeline Implementations in C#: TPL Dataflow Async steps and Disruptor-net
In the 3rd part of the series we'll see how to create asynchronous steps in the pipeline with TPL Dataflow. We'll also see a new implementation using the Disruptor-net library.
Pipeline Pattern in C# (part 2) with TPL Dataflow
In the First Part of the series, we talked about the Pipeline Pattern in programming, also known as the Pipes and Filters design pattern. In this part, we'll see how to implement such a pipeline with TPL Dataflow.
Pipeline Pattern Implementations in C# .NET - Part 1
The Pipeline pattern is a powerful tool in programming. The idea is to chain a group of functions in a way that the output of each function is the input the next one. The concept is pretty similar to an assembly line where each step manipulates and prepares the product for the next step.
Class Instantiation Guidelines in Object Oriented Languages: When to choose Singleton, Static, Extension methods or Dependency Injection
I'd like to tackle an old dilemma: Class instantiation. Which pattern do you use to create a class? Do you always use a new statement? Do we still need to use Singleton or Factory? Should we always use dependency injection? How about static classes, are they truly evil?
Performance Showdown of Producer/Consumer (Job Queues) Implementations in C# .NET
I recently wrote 3 blog posts on different Producer/Consumer (Job Queues) implementations. In this article, we will compare performance of all the approaches, including...
C# Job Queues (part 3) with TPL Dataflow and Failure Handling
In this article, we'll see how to implement Job Queues with TPL Dataflow, including implementations of several of the said variations. We will dive into the Dataflow mindset along the way, figuring out this awesome library.
C# Job Queues (part 2) with Reactive Extensions and Channels
In the last article we talked about what are Job Queues in C#. We saw several great implementation using BlockingCollection and the thread-pool. In part 2, we'll see a couple of great ones including...
C# Job Queue Implementations in Depth - Part 1
One of the most powerful tools in programming is the Job Queue. It's a simple concept that stands in the core of many software solutions. It's also a pretty interesting programming challenge, especially in a versatile language like C#.
