[$] A 2018 retrospective

The December 20 LWN.net Weekly Edition is the final one for the year; as
usual, we will be taking the last week of the year off for a brief rest.
LWN, which is about to conclude its 21st year of publication, has had the
time to build up some traditions, one of which is a year-end retrospective
that evaluates the predictions we made back
in January. As usual, some of those predictions aged rather better than
others; read on for our report card.
