Seeing usually smart folks getting rope-a-doped into arguing for LLM utility like there's a moral justice zero-sum trolley-problem slider between "useful" and "ethical" and we're just arguing about the best setting
But the real problem is even dumber
-is its mere use a climate disaster? Yes
-is its data provenance founded on theft? Also yes
-will it be used to ruin ordinary workers' lives? Yup
-will it ruin countless organizations wh…

“Apocalypse forces us to radically change. But by facing the future with optimism instead of doom, we can transform ourselves into the kinds of people-the kinds of communities—who can survive.”

New shelves came in, went ahead and pulled the shorter ones out, installed the full length ones, installed the supports, and cleaned up the power cables. Also adjusted the hooks on the back so they make a bit more sense.
Do the new shelves seem crooked? Yes. However they should support the MS-A2s a bit better.

Yale Climate Connections (YCC) is an excellent resource for anyone interested in climate and extreme weather, and among other things they host the Jeff Masters / Bob Henson "Eye on the Storm" blog, which ran under another name on the old #Wunderground site. I don't need social media, I have the EotS comments section. Their coverage of

Why donate to Yale Climate Connections?
Only 28% of Americans regularly hear about climate change in the media, but 77% want to hear those stories.

YSO Jets Magnetocentrifugally Driven by Reconnecting Atmospheric Avalanche Accretion Streams Above Inner Circumstellar Disks
Fast, collimated jets are ubiquitous features of young stellar objects (YSOs). They are generally thought to be powered by disk accretion, but the details are debated. Through 2D (axisymmetric) MHD simulations, we find that a fast ($>100$~km/s) collimated bipolar jet is continuously driven along the north and south poles of the circumstellar disk that is initially magnetized by a large-scale open poloidal field and contains a thermally ionized inner magnetically active zone surrounded by a dead…

Imposing the Fundamental Dynamical Constraint of Hydrostatic Balance to Improve Global ML Weather Prediction
Forecasting weather accurately and efficiently is a critical capability in our ability to adapt to climate change. Data driven approaches to this problem have enjoyed much success recently providing forecasts with accuracy comparable to physics based numerical prediction models but at significantly reduced computational expense. However, these models typically do not incorporate any physics priors. In this work, we demonstrate improved skill of data driven weather prediction approaches by incor…

Meter-scale Observations of Equatorial Plasma Turbulence
The multi-Needle Langmuir Probe collects an electron current through four fixed-bias cylindrical copper needles. This allows for an extremely high sampling frequency, with plasma properties being inferred through polynomial fitting in the current-voltage plane. We present initial results from such a multi-needle probe mounted on the International Space Station, orbiting Earth at an altitude of around 400 km. That altitude, and its orbital inclination (~50 degrees), place the ISS as a suitable p…

Highly Variable Magnetic Pressure-Driven YSO Jets in the Polar Cavity from Toroidal Fields Generated by Inner Disk Accretion
Jets and outflows are commonly observed in young stellar objects (YSOs), yet their origins remain debated. Using 3D non-ideal magnetohydrodynamic (MHD) simulations of a circumstellar disk threaded by a large-scale open poloidal magnetic field, we identify three components in the disk-driven outflow: (1) a fast, collimated jet, (2) a less collimated, slower laminar disk wind, and (3) a magneto-rotational instability (MRI)-active turbulent disk wind that separates the former two. At high altitude…
