Any suggestions on how to get something like this a…

Any sufficiently advanced disaster preparedness is indistinguishable from revolutionary dual power. This essay is a bit of a transition between the theory I've written earlier, and more concrete plans.
Even though I only touched on my life on the commune, it was hard not to write more. These are such weird spaces, with so much invisible opportunity. But they're also just so unique and special. For all the stress and uncertainty of making sure you stayed on Lorean's (the head priestess), there were also those long summer nights with the whole community (except the old lady) gathered around a fire, talking and drinking. There was almost a child-like play to the whole time.
There were so Fridays I'd come home with a couple of gallons of beer from the real world, folks would bring things from the garden, someone would grill a steak, everyone who didn't cook would clean up, and we'd just hang out and have fun. So many evenings I'd go over to Miles place with a guitar, or with his guitar, and we'd pass it around over a few beers, talking about philosophy, Star Wars, or some book or other. It's hard not to write about the strange magic of that space.
My partner and I bonded over similar experiences, mine on a weird little religious commune in California and theirs as a temporary worker at Omega Institute. Both had exploitation, people on weird power trips, frustrating dynamics, but also a strange magic and freedom. Both were sort of fantasy worlds, but places that let us see through this one, let us imagine something that something else is possible behind the veil.
There are many such veils.
Perhaps it's fitting that this is more meandering, as a good wander can help the transition between lots of hard thinking and lots of hard working.

Editing feedback (especially typos, spelling, grammar) is always welcome, as are questions and even wider structural advice. I've been adding the handles of folks who provide feedback to the intro in a "thank you" section. If you do help and wouldn't like to be added, please let me know.

STM32MP2 XC7K160T PCIe test board progress! 66 unrouted nets in the power supply, but I think it'll fit.
There's something for everybody in this board:
* 0201 passives? Check (under the SoC)
* Lots of FPGA? XC7K160T is decently sized
* Lots of CPU? Dual A35s, a M33, a M0 , and a M4
* High speed? PCIe gen2 and a SFP that is theoretically capable of 8 GT/s but I'm gonna try pushing the FPGA a bit and see if I can make it do 10Gbase-R with acceptable BER…

I bought some of these for a project and only realized once I had them that they are effectively gender changers and require USB-A-to-USB-A cables, which aren’t allowed by the USB spec.
I see that nevertheless such cables exist, and it’s for power only, but I wonder whether this can actually work?
Any ideas?

So the temporary placeholder name "Your Party" is made permanent.
None of the options on the shortlist were good. Most of them just as grammatically inconvenient as the dumb placeholder name.
The people who decide on the short-list, who can be a member, whose votes counts and what the options are, have quite a lot of power.
Zara Sultana boycotted day one over who sets the rules and who can be involved. If Your Party have a governing body with power to override conference they end up like the Labour party and just are easily taken over and usurped by a cabal of thatcherite neoliberal capitalists.
They did allow the dual membership system and a wider governance, so Zara won on who gets to be a member and who gets to be in charge. Which is probably good.
Coz as the terrible name shows, if you put the idiots in charge you'll get idiocy not good collective decision making.
For now the membership appear to have won, and I hear are they are all very excited and fierce and canny and not likely to let the old guard just set up another dictatorship from the top.
They currently have half the membership count of the greens, less than a quarter that claimed by Reform. Lets hope they can get some attention towards something other than how billionaires think the country should be run and focus on the people.
Here's hoping they can inflate that number by draining the Labour party and Reform members who just want change really rather than actually liking anything said by Farage.

Infinite-dimensional Lagrange-Dirac systems with boundary energy flow II: Field theories with bundle-valued forms

Abstract: Part I of this paper introduced the infinite dimensional Lagrange--Dirac theory for physical systems on the space of differential forms over a smooth manifold with boundary. This approach is particularly well-suited for systems involving energy exchange through the boundary, as it is built upon a restricted dual space -a vector subspace of the topological dual of the configuration space- that captures information about both the interior dynamics and boundary interactions. Consequently, the resulting dynamical equations naturally incorporate boundary energy flow. In this second part, the theory is extended to encompass vector-bundle-valued differential forms and non-Abelian gauge theories. To account for two commonly used forms of energy flux and boundary power densities, we introduce two distinct but equivalent formulations of the restricted dual. The results are derived from both geometric and variational viewpoints and are illustrated through applications to matter and gauge field theories. The interaction between gauge and matter fields is also addressed, along with the associated boundary conditions, applied to the case of the Yang-Mills-Higgs equations.
