I've been using Copilot for almost 10 months, useful when learning new code but after a while become a bit more advanced auto complete.

I think it is good for short lines, repeating tasks; for example when writing tests and want to assert different fields, assert string, int, etc; for these sort of lines was really good and fast.

my main problems: 1. sometimes make a horrible mistake, takes couple of minutes to understand 2. repeat the same mistake over and over 3. adding a single tab take a bit of time, had to copy & paste tab to avoid copilot suggestion!

Thanks for suggestion, played with CDK a little while back, much better than others.

What I'm looking for is some sort of advanced, battle testes designs or patterns. for example found iam role permission boundary.

I’m in a very similar situation, and recently have been laid off. My plan is to find an open source project which is aligned with what I am looking for. My main problems are staying focused in one area and mastering it.

I'm not sure that working on an open source project is good way to learn a new subfield of coding. I've done it and, in retrospect, this time could've been better spent elsewhere.

When working on an opensource project, you'll become an expert on the few functionalities (and code that realises it) of that single project that you will be working on - while you'll be oblivious about everything else in the subfield. IMO just doing a project that's typical for the subfield will allow you to learn much more. So, for example, when learning ML, don't go do obscure work on R codebase, but instead try some simple challenges from Kaggle.

Sorry to hear this. I hope things are OK, I’m trying to find it too, failing almost everyday.
