Hi, Manlio. I like your idea of putting the reusable code in a separate Git repository, and then vendoring it into the application project. That makes a lot of sense. I hadn't thought of that. Thanks for the idea. I also like the idea of making it an internal package, and move it to a separ

Hi, Manlio. Thank you for your reply! The project is an application, however, I’m planning to write the underlying components so they are reusable, so they can be leveraged elsewhere. Since I will be using the packages to build an app, I need to make sure the builds are reproducible. ☺ I ha

Hi Folks, So some good news on the issue but still not out of woods. After getting rid of all statically built libs and replacing them by dll's, I was able to compile and link against GO code. So far so good, but when running a test I get an error code: exit status 3221225781 getting closer :)

I make a test to see the performance of select, and found the result is not good. I make 1000 SeqQueue objects and run its messageLoop function (which does a small piece of work, and is listed as below) in 1000 separate go routines. The CPU cost is more than 20%. If I make the ticker 1 second,
