The "doomed" project, which had cost me over three months to finalize just came back from review and it got really nice, helpful and easy to fix comments! Fantastic, fantastic, fantastic! It was a massive amount of work and I'm very relieved that I don't have to do much more to get it out to the world.
Additionally, my promotion application was granted, so I will jump to the next academic and salary level at the beginning of next year!
I'd say, the December has started well so far!
