Course Description
The mood in the meeting on the 12th floor of an international investment bank was as bleak as it gets. The developers of the firm met to discuss the best way forward after a critical core application failed and caused a system wide outage.
"Guys, we have a serious issue here. I found out that the outage was caused by a race condition in our code, introduced a while ago and triggered last night." says Mark Adams, senior developer.
The room goes silent. The cars outside the floor to ceiling windows slowly and silently creep along in the heavy city traffic. The senior developers immediately understand the severity of the situation, realizing that they will now be working around the clock to fix the issue and sort out the mess in the datastore. The less experienced developers understand that a race condition is serious but don't know exactly what causes it and therefore keep their mouths shut.
Eventually Brian Holmes, delivery manager, breaks the silence with "The application has been running for months without any problems, we haven't released any code recently, how is it possible that the software just broke down?!"
Everyone shakes their heads and goes back to their desk leaving Brian in the room alone, puzzled. He takes out his phone and googles "race condition".
Sound familiar? How many times have you heard another developer talking about using threads and concurrent programming to solve a particular problem but out of fear you stayed out of the discussion?
Here's the little secret that senior developers will never share... Multithreading programming is not much harder than normal programming. Developers are scared of concurrent programming because they think it is an advanced topic that only highly experienced developers get to play with.
This is far from the truth. Our minds are very much used to dealing with concurrency. In fact we do this in our everyday life without any problem but somehow we struggle to translate this into our code. One of the reasons for this is that we're not familiar with the concepts and tools available to us to manage this concurrency. This course is here to help you understand how to use multithreading tools and concepts to manage your parallel programming. It is designed to be as practical as possible. We start with some theory around parallelism and then explain how the operating system handles multiple processes and threads. Later we move on to explain the multiple tools available by solving example problems using multithreading.
In this course we use Google's Go programming language with its goroutines, however the concepts learned here can be applied to most programming languages.

This is truly an excellent course, but if you don't know the basics about Golang, maybe you should look for an introductory course first. Still, if you're looking to learn more about how to use Golang in a multithreading way, this is probably what you were looking for.

James is an outstanding instructor. He explains concepts in a concise and intuitive way. There are great coding exercises to help students reinforce their learning. The material he's prepared is fundamental for any developer looking to utilise concurrent programming in their projects.
By Diego C. Rodrigues on 2/1/2022
The course is amazing! The way the instructor conducts the classes is amazing. Just one note that the first example of boids was not so good because the example had a high complexity so we spend to much time to understand and we loose the focus of the course that is about threads in go.
By Sean Macdonald on 1/10/2022
The examples chosen are well thought out. Not too academic or contrived. They perfectly illustrate the concepts. I am very impressed. After little effort, I have a much more solid understanding of concurrency features in Go
By Dmitriy Lozhkin on 1/8/2022
This course has a lot of interesting, non-trivial examples using both in-built multithreading tools in go and some other techniques. Thank you for the course, really enjoyed it! This is one of the best courses I've watched on Udemy.
By Nav M on 12/21/2021
This course provides a clear and appropriately concise coverage of background theory, followed by a practical coding example. This is an excellent format that strikes the perfect balance between theory and practice. The instructor speaks clearly and carefully uses precise terminology without undue pauses and does not rush the topic. The visual guides are appropriately minimalistic, consistent and well-timed. This was the best course I have so far come across on Udemy.
By Bruno Zica2 on 6/17/2021
A strong point is that the teacher actually answers the questions and he answers very carefully. What could be improved is adding exercises for us to try and really absorve the content. I think the examples sometimes are too advanced, and since the teacher implements the solutions, we don't have time to elaborate for ourselves. I like the topics he covers during the course.
By Alexander Betz on 11/10/2020
Mastering multithreading, suggest the the course deals with all aspects of multithreading, yet this course is far from achieving this. However, the material presented is excellent, albeit at times overly complex. The course feels very incomplete. I hope the author addresses this over time. At the moment the course ends abruptly with chapter 7. If by the time you read this the course has 14 chapters, ignore this and assume 5 stars from me.
By Adam Niedźwiedź on 8/28/2020
The theory was explained in a great way. However, I think examples were too complex. The art of passing knowledge is to use examples as simple as possible. Here, I cannot deny, the examples were spectacular, but I would rather to focus on the topic than how to calculate the movement of the boid. The best section is the Deadlocks. Examples are spectacular and not too complex. Overall the course is very interesting. In the docs, I see the sync lib has also Map, Once, and Pool. It would be nice if the author says a few words about them also.
By Tulio Ruiz on 5/16/2020
This was a good course, I'd love that it was a little more in depth in some topics like the pool worker and condition variables as the course is called "masterig" I wanted to see more in depth information, but I liked it very much, the examples and the explanations are good. If the author decides to expand it I'd definitely do it
