Ring founder 'backs the blue,' says AI is helping Amazon-owned doorbell unit fight crime
Ring founder Jamie Siminoff returned to the company he founded in April to lead the business, which is part of Amazon's devices division.

Update on attempt to emulate a Shockwave Director web page: I have tried the DirPlayer Chrome extension but get this error:

I included both <object> and <embed> tags pointing to the same .dcr file. Does anyone have other emulators to recommend?

Predictive Criteria for Electrospray-Assisted Droplet Dynamics in Aerodynamic Flow Fields
Electrospray technology enables external electric fields to steer charged droplets, with potential applications in fuel-air mixing and aerodynamic flow control. This study develops a computational framework that couples a steady OpenFOAM RANS solution of a NACA 1912 airfoil channel flow with a reduced-order Lagrangian particle model to examine droplet trajectories under viscous drag and electrostatic forces. Baseline uniform-flow tests confirmed that electrostatic deflection weakens as inertial…

Red onions make better solar panels 🧅☀️ Scientists in Finland and the Netherlands made a biofilm from onion skins that blocks 99.9% of UV and boosts solar durability. 🌍⚡ #solar #renewables #onions

@… AFAICT, Cloudflare’s durable objects are a kind of persistent actor, and I think it’s well-known that actors and OOP have problems with hidden state getting out of sync. Akka’s persistent actors have similar trouble eventually.
It’s a trade-off; you’re trading simplicity (state is in one place and strongly consistent) for speed (state is loca…

Lough Neagh in Northern Ireland has a serious cyanobacteria bloom problem and doesn't look like it will improve anytime soon. The system is hypereutrophic, with more than half of the phosphorus load coming from agriculture, but also a large contribution from aging wastewater treatment plants.

Droplet rebounds off a fluid bath: kinematic match simulations and experiments
We present a method to simulate non-coalescing impacts and rebounds of droplets onto the free surface of a liquid bath, together with new experimental data. The method is derived from first principles and imposes only natural geometric and kinematic constraints on the motion of the impacting interfaces, yielding predictions for the evolution of the contact area, pressure distribution, and wave field generated by the impact on both impacting masses. This work generalises an existing kinematic-ma…
