I've mentioned this before. Masha Gessen says you know when you have moved from democracy to autocracy when you stop saying, "It can't happen here," and start saying, "It won't happen to me."

The opening of this article makes me think that there is some parallel comment that applies to the Florida Coast and rural much of California. Probably other places as we better see long-term climate impacts.

Something like...
You know climate change has become a problem when you stop saying, "It won't happen here" and you start saying, "We'll probably be okay."

>drag

Could you fill the gaps with some lightweight foam? That should actually add some rigidity (like a SIP or a filled bollard), though not much

Endorsed by honey bees the world over. And then copied by engineers for application in military aircraft, skis and lunar landing modules.

It is the same thing in a way.  You can't remove the risk from the economic equation.  Also, crystal balling is getting harder.  Like what is the conflict around the strait of Hormuz going to do to oil consumption in the next couple of years?  Getting oil that isn't from a war zone is good for people who produce elsewhere.  Yet, I am sure EV sales are going to increase due to supply issues and once a consumer switches to EV, they are permanently consuming less oil.

The biggest group seems to be people who dont want to write but have to for their job or feel like they have to.

I have to believe this is a brief window in time where that type of writing still has legacy value, but that value will soon be gone, especially given the big jump with Claude Fable (Mythos but fences to try to prohibit security use/exploit)

Been looking for an excuse to post Ethan Mollick's first look

All 50 leases would be $96 million and 95% failed?

I wonder how much is the pure economics and how much is fear that a new admin will revoke them.

1 inch tall grid like that on the roof is going to create a ton of drag. I asked Gem about any kind of plastic/polymer sheet material it could think of. It said for the application, aluminum is the absolute best.

FRP might work.  It's used for pier decking now.  A similar aluminum grid panel is used in farm equipment a lot --these may be cheaper since they're sorta commodity items.

Update: Moving in the right direction, but sheesh. I need to find the Chinese equivalent of SendCutSend to make this viable.

I want to cut some aluminum sheet to add a walkable roof deck to my SUV's aftermarket roof rack.

The panel is 39 inches by 23.5 inches, material is .25 inch 6061 aluminum. Need four copies of this panel.

I fed Gemeni the use case, roof rack support specs. I asked it for a slotted holes design, then a round holes design, then a hexagon holes design to minimize weight while maximizing strength.

It said hexagons are the most efficient. I asked it to optimize the hexagon size and spacing for the use case.

Unfortunately, the first optimized design was a small, dense hexagon pattern with 2,800 holes. The fabricators said the laser will warp the panel with the tight spacing. Also the initial burn through for a new hole takes extra time, raising cost. I did get one quote back for $36,000, heh.

The below photo is an updated version with larger hexagons. Trying again today with the simplified design.
