[go-nuts] Re: Accessing Slices Made From Same Array Concurrently

I am pretty sure that you will run into problems with this. On one hand passing pointers could lead to a write after a read, and on the other hand with pass by value you could get an out of date value and then stomp over another process write. I'm pretty sure the race detector will flag this.

Indeed it is possible to set the $GOPATH in a shell. And if I use other tools with a specific project, for example VSCode, then I have to start all of them from the same terminal. Which is not the most desirable outcome. Anyway, as I have mentioned before, this solves nothing when multiple

There could have been a data race in your code with the usage of allMax variable which is updated and checked by multiple goroutines. But you are saved by the use of mutex. All shared variables, in general, are subject to data races when there is a write involved. The local variables you create
