That was long before current events, not that I would have had much influence in that particular case, similar to some of the other talented security people who still work there. I liked the language when I tried it but then got away from programming in it for a while due to the particular problems I was solving. I’m exploring it again to see what has changed.

Number one reason to use Golang? Built-in Concurrency

Whenever selecting a technology, you should have a reason. The reason should not be “because all the cool kids do it.” In this case, I’m considering using Golang because of the way it handles concurrency. What’s that? I’ll explain in a few simplified pictures.

In this first picture, the program executes the steps sequentially. Each step takes 2 seconds to run the program. The program takes 8 seconds from the start of execution to…
