In order to process a lot of work we have to parallelize work across all cores, and especially if it’s CPU bound. Go has goroutines, which can be used to parallelize the work, but there is the cost of context switching for a lot of goroutines. Minimizing this context switching can be achieved by using a fork-join model when processing work. Parwork solves this problem by using goroutines, channels and waitgroups. It creates workers (goroutines) that pull work of a queue (channel), process the work and report the work back to a queue (channel). This is done in a abstracted way so the user has to provide implementation for: ...

A lot of times i was wondering what is the best performing code. In order to determine that i had to benchmark my code, but benchmarks are hard to write. Luckily there is a open source project that does this work perfectly good and very easy. The name of the library is BenchmarkDotNet and the documentation can be found here. The only thing you have to do is: Create a console application project (.NET/.NET Core) Install the nuget BenchmarkDotNet and it’s dependencies Always run in release mode! The following code is needed in the Program Main ...

This is probably one of the most useful “cloud” patterns out there and it is fairly easy to implement. There are great articles and implementations, like Polly, already on the internet about this pattern so why another one? Κρείττον οψιμαθή είναι ή αμαθή.

The presentation was about the current state of .NET Core in the Linux World. Here are the slides of the presentation and the github repository. Thanks for attending.

Yes, i know not this again. Is this not the one millionth time that someone blogs about that? Yes, yes and yes but… It is always good to repeat things and we all know that “Repetition is the mother of learning, the father of action, which makes it the architect of accomplishment.” ― Zig Ziglar There are still implementations out there that might benefit from this… So let’s start with some definitions. ...
