Lunchtime links

Even when I work from home, I have a lot to do. At least I don't have a commute today, giving me extra time to catch up later:

• On March 8th, The Hitchhiker's Guide to the Galaxy turns 42. Yes, 42.
• It won't surprise anyone to learn that Donald Trump sucks at business. He certainly sucks at medicine. And at nominating people properly.
• Farhad Manjoo wants to live in Elizabeth Warren's America, and so do I.
• Josh Marshall analyzes why Bernie Sanders hit a wall last night.
• Philip Bump explains what happens to delegates when a candidate drops out.
• February set another record for the Lake Michigan-Huron system's water levels, causing extensive damage to beaches.
• Winter 2019-20 ended Sunday. In Illinois, though February was pretty normal, the winter itself was not.
• Let's Encrypt needs to invalidate most of its certificates due to an error.

And now, back to work.
