Open Thread #40

The last Open Thread was in Oc­to­ber 2017, so I thought we were over­due for a new one.

Use this thread to post things that are awe­some, but not awe­some enough to be full posts. This is also a great place to post if you don’t have enough karma to post on the main fo­rum.

Con­sider giv­ing your post a brief ti­tle to im­prove read­abil­ity.
