Of course market participants agree?

Exchanges have calculation rules for every type of mark and payment and will always specify rounding.

Paris would need significant infrastructure work across the distribution system to handle AC at NYC’s rate of 90% on summer heat wave days.

Sure he does.

It's not handwaving to complain that shipped features are never completed and a functional CLI for fundamental and critical tasks is never delivered.

The same way you get value out of a dev container.

Regulators don’t want to provide arbitrarily detail into their interpretation or likely judgements on issues that may come up for many reasons, good and bad.

One good one is that providing concrete razors for compliant and non-compliant behavior accelerates the gaming of the rules.

How are resource and territorial pressures not environmental pressures?

If you take Pliny’s word for truth, they did achieve 10% of the scale of the largest currently operating gold mine using hydraulics at Las Medulas.

Modern geological estimates are radically lower.

Cool. It is!

Tack is short for tackline, a length of line used to delimit messages encoded with flags in the days before shipboard radio communications.

Military and civil emergency communications use alternative pronunciations where clarity and brevity are critical.

This is one of the most sustained bad-faith arguments I’ve seen on HN.

The idea that 4 of the largest investment banks in the US were destroyed is not just utterly false, it’s hard to imagine how one could interpret the outcome in this manner.

Why would anyone be happy that the government offered handouts that were stolen, low-level criminals prosecuted, meanwhile every single principal who was culpable went unpunished?

I don’t need to hear from you how this is off-base or I’m misunderstanding. I’m close to principals involved in the crisis and worked for years in the response to it, and have heard what went on in the meetings dramatized afterwards.

These companies innovate in all of those areas and direct those resources towards building hyper-scale custom infrastructure, including CPU, TPU, GPU, and custom networking hardware for the largest cloud systems, and conduct research and development on new compilers and operating system components to exploit them.

They're building it for themselves and employ world-class experts across the entire stack.

How can NVIDIA develop "more integrated" solutions when they are primarily building for these companies, as well as many others?

Examples of these companies doing things you mention as being somehow unique to or characteristic of NVIDIA:

Complex kernel drivers or modules:

- AWS: Nitro, ENA/EFA, Firecracker, NKI, bottlerocket

- Google: gasket/apex, gve, binder

- Meta: Katran, bpfilter, cgroup2, oomd, btrfs

Hardware simulators:

- AWS: Neuron, Annapurna builds simulations for nitro, graviton, inferentia and validates aws instances built for EDA services

- Google: Goldfish, Ranchu, Cuttlefish

- Meta: Arcadia, MTIA, CFD for thermal management

Optimizing Compilers:

- Amazon: NNVM, Neo-AI

- Google: MLIR, XLA, IREE

- Meta: Glow, Triton, LLM Compiler

Acceleration Libraries:

- Amazon: NeuronX, aws-ofi-nccl

- Google: Jax, TF

- Meta: FBGEMM, QNNPACK

You're generalizing a failure at delivering one consumer solution and ignoring the successful infrastructure research and development that occurs behind the scenes.

Meta builds hardware from chip to cluster to datacenter scale, and drives research into simulation at every scale, all the way to CFD simulation of datacenter thermal management.

You might be confusing conservation of momentum and energy with respect in the context of elastic and inelastic collisions.

In a perfectly elastic collision, both momentum and kinetic energy are conserved.

As you say, many real collisions are inelastic to a significant degree. In these cases, momentum is still conserved, but the kinetic energy is converted to another form of energy.

Conservation of linear and angular momentum are fundamental and exact laws of nature resulting from translational and rotational invariance.

The air doesn’t need anything “else” to push against. It pushes against itself and the balloon. Conservation of momentum will cause propulsion.
