If the deceased turns out to have been lawfully armed
and ICE unlawfully attempted to detain him for filming,
does that that mean ICE just executed someone for exercising their 2nd Amendment rights?
ETA: The Minneapolis chief of police just stated on CNN via WCCO that they believe the victim did have a permit to carry.
They shot him AFTER the gun was removed from his person.
And then double and triple and quadruple tapped well after obvious signs of death.

apparently, the velvet underground did a quad broadcast in the bay area in june 1970, aired on KQED/KPFA. maybe taped at their final san francisco shows in late '69, so some more MIA (pro mixed) tapes!? via @grantmcphee.bsky.social awesome VU project. https://grantmcphee.substack.com/p/the

I needed to build up our inventory of parts to build our network testing products.
So I discover:
1. The Chinese vendor who makes the motherboards has stopped shipping to the US.
2. The memory I need - pretty basic 16gb DDR 4 and 5 SODIMS - unavailable or more than quadrupled in price.
3. M.2 NVME SSDs - unavailable or much higher prices.
F**k those AI companies especially the one that bought all those memory wafers it can't use just to block its competition…

Determination of nuclear quadrupole moments of $^{25}$Mg, $^{87}$Sr, and $^{135,137}$Ba via configuration-interaction plus coupled-cluster approach

Abstract: Using the configuration-interaction plus coupled-cluster approach, we calculate the electric-field gradients $q$ for the low-lying states of alkaline-earth atoms, including magnesium (Mg), strontium (Sr), and barium (Ba). These low-lying states specifically include the $3s3p~^3\!P_{1,2}$ states of Mg; the $5s4d~^1\!D_{2}$ and $5s5p~^3\!P_{1,2}$ states of Sr; as well as the $6s5d~^3\!D_{1,2,3}$, $6s5d~^1\!D_{2}$, and $6s6p~^1\!P_{1}$ states of Ba. By combining the measured electric quadrupole hyperfine-structure constants of these states, we accurately determine the nuclear quadrupole moments of $^{25}$Mg, $^{87}$Sr, and $^{135,137}$Ba. These results are compared with the available data. The comparison shows that our nuclear quadrupole moment of $^{25}$Mg is in perfect agreement with the result from the mesonic X-ray experiment. However, there are approximately 10\% and 4\% differences between our results and the currently adopted values [Pyykk$\rm \ddot{o}$, Mol. Phys. 116, 1328(2018)] for the nuclear quadrupole moments of $^{87}$Sr and $^{135,137}$Ba respectively. Moreover, we also calculate the magnetic dipole hyperfine-structure constants of these states, and the calculated results exhibit good agreement with the measured data.
