I heard about Over The Garden Wall ↗ series for the first time two days ago. It is an almost 10 years old miniseries with runtime of 1 hour 40 minutes. It is rare to find a series with so much care given to it; I can wholeheartedly recommend it. The miniseries format gives it a short runtime and gave the creators incentive to tie all the knots, an important feature that I seek in any series that I consider watching. I will not do a thorough analysis of the series as it seems internet has enough of those.
Aside from the above recommendation a post about Representative Sets, a technique to design parameterized algorithms, is being prepared and should be ready by the end of this week.
