TODAY'S COMIC: Crabby
PANEL 1: A red-orange crab stands on sand with a blue sky behind him. Next to him is a paper coffee cup with lid and a brown sleeve.
CRAB: Before Coffee: Crabby.

PANEL 2: The same scene.
CRAB: After coffee: STILL CRABBY.

PANEL 3: The same scene, the crab stares at the viewer.

PANEL 4: The crab turns to the side, thoughtfully.
CRAB: …but better able to articulate why.

Cut down from a 2 minute shot (also trimmed to fit flickr's 1G/1080p limits.)  Heron pouncing on and eating a small fish. Loud aircraft noise, I recommend muting.

Engineering ethics are complicated and imperfect, but I will always vividly remember how my Materials Science professor opened the course by showing us pictures of the Hyatt Regency walkway collapse and then walking through the free body diagram diagramming the exact mistake that caused the disaster

Meme thoughts while I was riding to Babes Bike Boston 🚴🏻‍♀️
A meme in two parts. Top is a photo of a speed limit sign on a road declaring it a safety zone with a 20MPH speed limit. Text reads "reject artificial speed limit signs that drivers ignore." Bottom is a collage of photos of turkeys in the middle of streets in Cambridge/Somerville. Text reads "Embrace natural, chaotic traffic calming measures"

The image is of a four panel comic.
In the first panel we see a dragon sitting on a pile of treasure. A speech bubble pointing off panel reads, “Dragon, why do you have all this treasure?”
In the second panel we zoom in on the dragons face. He simply says “shiny”.
In the third panel we pan to the left and see that there is a crow standing next to the dragon on the treasure.
In the fourth panel we zoom in on the crows face. He says “hell yeah”.

Coyote v. Acme was glorious. (Granted, it might as well have been made for me personally; the classics were one of the unmistakable influences on my choices of career. But they made *excellent*, even respectful, use of the source material, and the new stuff *clicked*.)

As we approached maximum eclipse, my camera's long moon exposure mode really wasn't helping so I finally set up a tripod.  (Also it had gotten pretty hazy, but the moon wasn't *completely* hidden from here.)  What Doctor Becky Smethurst refers to as a "toenail moon", but in a "wrong" orientation...

Digital zoom (and haze and tiny phonecam aperture) makes this look like a watercolor, but it does get it across, especially if you remember that this was *full* 2 hours ago :)

Might lose it to clouds before peak, but for now they just give it a Spooky look.
