In short, most peasant farmers must sharecrop at least some of their land, and on sharecropped land, extraction rates are on the order of 50% (for basically nothing in return).
You can still draw arcs without sideways slipping. If you do out the math, you’ll see that a skater traveling in a circle has no sideways velocity, but does have sideways acceleration.

Social dancing’s demise has been greatly exaggerated! If you live in any moderately large city, there is almost certainly a swing dance scene, and you can find people doing social Latin (salsa, bachata) pretty much everywhere. My city’s swing dance club has a social every Sunday, with events on most Saturday evenings too.
Whether you're looking to replicate your hometown, explore urban environments, or simply build something unique and realistic, Arnis offers a comprehensive toolset to achieve your vision.
I will however note that simply using an option in the return value is probably the best choice both API- and performance-wise. The consumer may want to do different things if the key doesn’t exist versus if the key has no neighbors. Additionally, returning an Option means there’s only one check for whether the retrieval was correct, rather than checking at every call to `next`.

While NASA requires its aerospace contractors to have quality assurance programs that comply with SAE International’s AS9100D standards on quality management systems, we found Boeing’s quality management system at Michoud does not adhere to these standards or NASA requirements.
The lack of a trained and qualified workforce increases the risk that Boeing will continue to manufacture parts and components that do not adhere to NASA requirements and industry standards.
Boeing’s delivery of the EUS to NASA has also been delayed from February 2021 to April 2027, and when combined with other factors, suggests the September 2028 Artemis IV launch date could be delayed as well.Mississippi welfare scandal: https://en.m.wikipedia.org/wiki/Mississippi_welfare_funds_sc...

Bret Devereaux (oft featured on HN) recently finished up a series on the Roman and classical Hellenistic tactical systems; for a view of an army doing sword-based combat, check here [1].

Oddly enough, Salman Rushdie’s Midnight’s Children covers this exact feeling almost in the same way as you describe. If you haven’t read it, I definitely recommend it - it’s a long read but also very enojoyable.
If you're interested in methods for actually learning policies for these sorts of dynamic motions, note that this paper is simply applying proximal-policy optimization. They're pulling in the training and implementation methods from Margolis's [1] and Shan's [2] work.
So, in sum, the contribution of this paper is exclusively the method for generating reward functions (which is still pretty cool!!!!!), not all the learning-based policy stuff.

It would be really nice to have fine-grained control over frame pointer inclusion: provided fine-grained profiling, we could determine whether we needed the frame pointers for a given function or compilation unit. I wouldn't be surprised if we see that only a handful of operations are dramatically slowed by frame pointer inclusion while the rest don't really care.
