The city’s chief, Brian O’Hara, confirmed the man had died following the incident, describing him as a white male and a resident of Minnesota.
The man was also a “lawful gun owner” with a permit to carry the weapon, O’Hara said, adding that the victim’s name was known to police but would yet be released.

Abstract: Collective patterns of motion emerge across biological taxa: insects swarm, fish school, and birds flock. In particular, large migratory birds form strikingly ordered V-shaped formations, which experiments and direct numerical simulations have demonstrated provide substantial energetic benefits during long-distance flight. However, the precise aerodynamic and morphological mechanisms underlying these benefits remain unclear. In this work, we develop a reduced-order model of the wake-vortex interactions between two flapping birds flying in tandem. The model retains essential unsteady flapping dynamics while remaining computationally tractable. By optimizing over a six-dimensional state space, which comprises the follower's three-dimensional relative position and three independent flapping parameters, we identify the energetically optimal leader-follower configuration of northern bald ibises. The predicted optimum agrees quantitatively with live-bird measurements. Because of its simplicity, the model allows for direct interrogation of the physical mechanisms responsible for this optimum. In particular, it isolates precisely how the follower's wing kinematics interact with the leader's wake to enhance aerodynamic efficiency. The model predicts an 11% reduction in total mechanical power for a follower in formation flight -- consistent with experimental estimates -- and shows that this saving arises from reductions in both induced and profile power, dominated by decreased profile power enabled primarily through reduced flapping amplitude and, secondarily, reduced upstroke flexion. These results provide a mechanistic explanation for the structure of V-formations and offer new insight into the aerodynamic principles governing collective flight.

Made new test prints on some off-cuts, using a slightly stronger developer solution than usual to see impact on max. depth. The main image (Eagle Creek, Oregon) is using 18% sodium acetate (curve corrected negative), the test strips are of 20% and 15% solutions (both uncorrected). The phone capture doesn't really show the differences too well, but I think I will go for the 18-20% from now on...

Why are we having fewer children?

- Couple formation happens at later age
- Women are choosing "careers" and not just "jobs"
- More people choose not to have kids at all

So here’s a little JavaScript initialisation order quiz.
Take the following code:
```js
class A {
constructor (parameters = {}) {
Object.assign(this, parameters)
}
}
class B extends A {
foo
constructor (parameters) {
super(parameters)
this.foo ??= ‘no’
}
}
const b1 = new B()
const b2 = new B({ foo: ‘ok’ })
console.info(`${b1.foo}, ${b2.foo}`)
```
What output would you s…

„It’s a path puzzle. You draw a path that enters the grid at the top and exits at the bottom. Along the way, there are 50 sections, each following a different ruleset. Consecutive sections overlap by a few rows, creating short hybrid sections in between.”
