Solar Power outstripped all others in Europe last Month for First Time

#SillyPoll about money 💰
Every month, with you newly-earned salary (or equivalent) do you generally:
(Note: option 1 means that if you suddenly get more money, like a bonus, you will buy something with it instead of saving it while option 2 means you would save it instead)

£13.2bn fund to fix draughty homes and install heat pumps and solar panels.
Nothing else that I can see on reduction of energy demand.
And here is the money being wasted:
'£30bn in investment in nuclear power, about half on the Sizewell C reactor'
Small tidal schemes in the Mersey, Severn and other estuaries would give a better, and safer, approach to "always on" energy supply.

Chiral non-Abelian domain walls in dense QCD
In this paper, we study chiral non-Abelian domain walls in a phase of unconventional vacua of dense QCD. The phase is characterized by asymmetric vacuum-expectation values (VEVs), for example with the left scalar field, corresponding to the left quark-quark condensate, having a nonvanishing VEV and the right field having a vanishing one. The domain wall soliton interpolates between this vacuum and another where the left and right scalar fields switch roles. We contemplate that such vacua could …

Hybrid Classical-Quantum Sampling for Lattice Scalar Field Theory
We investigate lattice scalar field theory in two-dimensional Euclidean space via a quantum annealer. To accommodate the quartic interaction terms, we introduce three schemes for rewriting them as quadratic polynomials through the use of auxiliary qubits. These methods are applied on D-Wave quantum annealer, and their effectiveness is assessed by examining the annealer-generated distributions. Using these distributions, we perform Monte Carlo sampling via the Metropolis-Hastings algorithm and c…

What Monads Can and Cannot Do with a Few Extra Pages
The delay monad provides a way to introduce general recursion in type theory. To write programs that use a wide range of computational effects directly in type theory, we need to combine the delay monad with the monads of these effects. Here we present a first systematic study of such combinations. We study both the coinductive delay monad and its guarded recursive cousin, giving concrete examples of combining these with well-known computational effects. We also provide general theorems stati…

Defense Secretary Pete Hegseth has ordered the Navy to rename the
USNS Harvey Milk,
a highly rare move that will strip the ship of the moniker of a slain gay rights activist who served as a sailor during the Korean War.
The change was laid out in an internal memo that officials said defended the action as a move to align with Trump and Hegseth’s objectives to
“re-establish the warrior culture

Pete Hegseth orders Harvey Milk's name scrubbed from US Navy ship
U.S. officials say Defense Secretary Pete Hegseth has ordered the Navy to rename the USNS Harvey Milk in a highly rare move. The ship was named after the slain gay rights activist who served as a sailor during the Korean War. The officials say Navy Secretary John Phelan put together a small team to rename the replenishment oiler, and that a new name is expected this month. It marks the latest move by Hegseth to purge diversity, equity and inclusion references, and it comes during Pride Month. T…

Here's an idea: People in tech want better AI criticism? It's all just too $something? I'm willing to take off a month from work to write a whole bunch of detailed structural criticism if the people demanding better, more specific criticism pay my salary for that month.

<<Global growth of power demand last overwhelmed growth of wind and solar. Power generation grew by 4.3%, or 1,293 TWh from 29,963 to 31,256 TWh. Combined wind and solar generation grew by just half that total, 649 TWh. The gap between the two, 644 TWh, was filled by 1) nuclear and hydro generation grew by a combined 272 TWh -unreliable growth technologies. Meanwhile, 2) coal generation continued to grow, by 152 TWh.>>
