Link not working, but no worries, no time to listen. I just find all this science on optimizing caffeine drug delivery kind of hilarious. I’ve seen the stuff on cortisol suggesting to wait an hour or two on waking. Not sure if that’s the same as the adenosine stuff. But I mean, it’s a drug. It’s interrupting naturally occurring cycles of cortisol no matter when you drink. It’s somehow more healthy to use coffee as a stop gap between cortisol cycles than as a multiplier during a cortisol cycle? I mean, come on.

I’ll take your word on the adenosine science, but coffee first thing in the morning definitely has a high impact, not a low impact.

Thanks! Yeah still looking. I know enough GIS to make the river into straight line segments defined by river length with each segment having the attributes of the census boundary it went through, but I don’t know what process to use to “warp” the census boundaries like on that ruler. On the ruler, the boundaries are abstracted bc they’ve been pulled/pushed to make a straight line, but they still correspond to the original geography/topology.

Anyone have an idea how to make a straight line representation of a river as a "ruler" attached to other polygon data, eg, surrounding census boundaries?

Like this ruler in the LA River Master Plan.

I know some GIS and can't figure it out, but I'm guessing this was done using D3 or something?
