The ancient Middle-East had a solution for surviving the heat without chillers: windcatchers (and the related solar chimneys). Such things should be employed for first-tier cooling where possible to reduce energy demand, leaving chillers to take up the slack (until we figure out how to get infinity gigawatts of free power into every house, at which point we should just capture all the excess heat from running chillers and use the Seebeck effect to convert it into electricity to power a giant…

Very interesting developments in Ukraine. I can only think it is normal for a state that is at war to have very strong opinions within its government.
“One participant in the president’s meeting with lawmakers recounted Zelensky’s words this way:
They live in two different worlds. [DM] Misha wants to digitize everything, to build a system around technology. The military just wants to be heard. They ask for one category of weapons to be procured, and he refuses and funds other areas instead. They’ve simply stopped hearing each other. I can’t allow the Defense Ministry and the General Staff to be at war with each other in a country that’s at war. Ideally, I’d replace them both. But I can’t do that at the same time.”
I just hope they can keep and achieve the goal to push Russia out of Ukraine.

Disney, DreamWorks Animated Titles Nab Nearly $72 Million In California Tax Credits
This round of subsidies is headlined by DreamWorks' 'Donkey,' Disney's 'Hexed,' and an untitled movie from Pixar. Changes to California's tax credit program expanded the eligible categories of production to include animation.

Rigid Functions, IP-Systems, and Topological Mild Mixing

Abstract: We study uniform rigidity and topological mild mixing through continuous observables. For a fixed sequence of times, the observables rigid along that sequence form a closed unital $T^{\pm1}$-invariant algebra and determine the maximal factor uniformly rigid along the prescribed sequence. We then give functional forms of the classical ${\rm SIP}^{*}$- and ${\rm IP}^{*}$-return-time criteria: a topological dynamical system is mildly mixing exactly when it has no nonconstant locally SIP-rigid observable, and in the minimal category the same property is equivalent to the absence of nonconstant locally IP-rigid observables. Finally, a locally IP-rigid observable yields a canonical orbit-name factor carrying marked local data. For fixed local data, the $T^{\pm 1}$-invariant core of the local rigidity algebra determines a uniformly rigid factor whenever the core is nontrivial.

CRAN Task View: Optimization and Mathematical Programming
This CRAN Task View contains a list of packages that offer facilities for solving optimization problems. Although every regression model in statistics solves an optimization problem, they are not part of this view. If you are looking for regression methods, the following views will also contain useful starting points: MachineLearning, Econometrics, Robust Packages are categorized according to the following sections. See also the “Related Links” and “Other Resources” sections at the end.
