By contrast, JB Pritzker told me that people should flood the No Kings protests precisely in order to let the American people know that something is deeply amiss. More Dems should be doing this, to send the message widely that we are in real trouble right now.

Ok it's Prime Day or whatever and Amazon is gross but also if we are ordering stuff there WHY NOT ADD ON A PREORDER OF MY JUSTICE-FOCUSED BOOK. It's broadly accessible and has a positive message and will make you feel better when it finally ships. Shamelessly, Love, Chad

Hey Twin Cities! Anybody need an aloe plant? I have two like this that were offshoots from a much MUCH larger one a year ago. And now that big one is putting up more shoots. The little ones are free to a good home. Let me know and weโll work out the details.

Hey friends! Little tech help, please? A highly specific ask. I understand that MathType equations in a Word document can be re-rendered in LaTeX in order to export for another medium (say google docs). But I don't have access to either Word or MathType.

Hot writing tip! It is very common, in a piece of writing that has any length at all, to know what a part of the writing needs to do without also knowing how you want to write it.

If you followed me over at the bad place you may remember how OBSESSED I was with Stick and Split. TT was 3 at the time and even at that age, he was developing a basic understanding of factors and multiples. So imagine my utter delight today to discover MORE mathy games! Off to play Number Ramble!
