Sharing here my strategy to dramatically increase noise/signal ratio from twitter (and stay sane). The problem: the timeline is full of garbage. Much of this garbage is semi-political pornography: very attractive, mostly cheap, and highly toxic. Adding new accounts to follow is a simple click. The immediate cost is close to null. But the long-term price is huge. It's a little bit like feature creep (en.wikipedia.org/wiki/Feature_c…). Add one account here, one account there. Easy.

I am in total LOVE with this book on the science of learning (learningscientists.org/book).

Many methods feel like they are useful (reading and rereading) but they are suboptimal compared to others (retrieving information from memory).

Reflections while teaching InfoVis for the zillionth time. The pedagogy of vis is heavily skewed towards accurately representing quantitative information. Fine. But there are a couple of fundamental notions we do not seem to spend enough time on. 1/ The role of "data transformation".

One of the unexpected advantages of being an homeschooling parent is that I discovered tons of material that any parent can use even if he or she is not homeschooling (in fact I use it with my other kids who are not homeschooled). Here are some of the main "gems" ... 1) Susan Bauer's "History of the World" series is so much joy (welltrainedmind.com/landing/story-…). I now read it to my kids at night when they go to sleep. They love the stories and they learn history while having fun.
