I haven't spent any time looking at Go because I'm pretty satisfied with Ada, but these libs do smell a bit like the Ada time handling functions which only get better through each ISO revision. Not handling dates like POSIX is nothing new, but it some of us just haven't been exposed to it. Of course, Ada would never guess at a format. Blasphemy. The more you know™
I am a freelance Ada developer who is currently working on a contact management system for call centers for a small company. It's the usual array of DB access, webserver and AJAX/websockets. The product is exclusively in Ada though it relies on Freeswitch currently and has recently allowed some Python scripting for calls. The front-end is handled by Ada Web Server which is a rather good Ada HTTP library among other things. Mounds of concurrency and threading in the product back-end.
