Welcome to the first video of Concurrency in Go video course. In this video you'll get a bigger picture of what Concurrency really is, a good theory grasp on Concurrency and Parallelism, and of course we will slightly touch on some Go examples. But it's all just scratching the surface. There's so much more we'll dive into this course.

Software engineering is one of the most accessible fields nowadays, but it's easy to get lost in the huge amount of technologies and ways to approach engineering problems. Lots of languages, frameworks, solutions and ways to be a productive engineer.
I share my own experience on what is like to be a software engineer and the skills required to be a productive one. On this channel I share my thoughts, opinions and video tutorials about topics related to a certain technology, to make it easier for you to ultimately make a choice or just get better at software engineering by learning from my mistakes/experience.
Make sure to also check out 5m Friday every Friday, where I share my thoughts and opinions about different engineering topics. I'll c you around 😎
Stay tuned!

Everything related to Go Scheduler will be discussed in later lessons, but now that you asked. When main exits it destroys all it’s child go routines and frees any kind of resources used

@SteveHook 3 жыл бұрын

Yeah it’s hard to dial things in, many devices and depends on the volume you listen at. I usually edit on headphones volume at 65% which is what most people have enabled. So it might be too loud for some, and normal for others 😅

Claiming "go routine" creates/forks a process kind of confuse us. It doesn't create a typical OS process i.e. you don't see a separate process while executing go routines. Go routine are kind of very lean OS threads.

But a very rich video you create. Thank you.

@SteveHook 3 жыл бұрын

I never said OS process. I explained that in the context of the Fork Join model. In that context the terminology is correct. I tried not to deviate from the topic, hence there will be many more lessons only on go routines which will explain that in details

@roku_on_it Жыл бұрын

I don’t find it helpful to define concurrency and parallelism in that way. We can simplify it with an example like this: Concurrency is writing to two papers with your one hand and switching between papers over time, and if you do it too fast it looks like you write to both papers at the same time but it’s not. Parallelism is writing both papers with both your left and right hand, literally, physically the same time.
