Again drones above Denmark, it is so strange they are not shooting them down, or at least one....🤔
Even if they don't pose a threat you have to sent a signal to the people that control them or collect evidence from the wreckage. Is there no air defence?
The drones don't drop bombs but cause damage and inflict costs, besides the psychological aspects.

Solar breakthrough—hotter panels mean better storage
Scientists have uncovered a surprising advantage in next-generation solar technology—the hotter it gets, the better it can store energy. Traditionally, heat has been seen as the enemy of solar power. Standard solar panels lose efficiency as temperatures rise.

Monodromy and rigidity of crystalline local systems

Monodromy and rigidity of crystalline local systems
We study several rigidity properties of $p$-adic local systems on a smooth rigid analytic space $X$ over a $p$-adic field. We prove that the monodromy of the log isocrystal attached to a $p$-adic local system is ''rigid'' along irreducible components of the special fiber. Then we give several applications. First, suppose that $X$ has good reduction. We show that if a family of semistable representations is crystalline at one classical point on $X$, then it is crystalline everywhere. Second, com…

One advantage of separate collection of plastic/packaging waste (here in the Netherlands) is that it shows us the amount of it.

Black holes black out: total absorption in time-dependent scattering
We uncover a new class of phenomena in gravitational physics, whereby resonances in the complex plane can be excited via tailored time-dependent scattering. We show that specific forms of temporal modulation of an incoming signal can lead to complete absorption for the entire duration of the scattering process. This, then, makes stars and black holes truly black. Such ``virtual absorption'' stores energy with high efficiency, releasing it once the process finishes via relaxation into the charac…

An angry rant about locales and filenames in libarchive.

stream_libarchive: workaround various types of locale braindeath · mpv-player/mpv@1e70e82
Fix that libarchive fails to return filenames for UTF-8/UTF-16 entries. The reason is that it uses locales and all that garbage, and mpv does not set a locale. Both C locales and wchar_t are shitf...
