Continuing my annual tradition, here's a new thread to celebrate the new year.
I wish everyone just one shutdown each this year. No shutdowns, and you aren't pushing hard enough. More than one, and you're pushing so hard that you'll miss out on good opportunities.
So just one per person, please!
Last year's thread is here, for reference:
2018 Shutdown Thread
And I'm seeding the Wiki with the info from that thread.
