I don’t know if it’s too early to ask but are there plans for this years AOC and donations from AdaCore? Would love to participate this time (and help donate to some cause)!
Last year it was very string and pattern intensive and I didn’t fully understood adas type system 
Advent of Code is going to be a bit different this year- Only 12 days instead of 25 and no global leaderboard. Private leaderboards will still be available.
I’m planning to work on the puzzles in Ada again, though I haven’t decided yet if I’m going to share my solutions on a daily basis or wait until the end.
Just when I thought I was out… they pull me back in.
I plan to do it all with HAC again, and add a short row to the regression tests on the way.
