Application of the Method of Moments to solve full wave formulation of Maxwell's equations. To derive the EFIE using maxwell's equations is a massive pain. With geometric algebra, all you need is ∇F = J and the MoM becomes a mechanical process.

Commission your own solar and battery system. There is no reason to be a renter anymore. Stop giving other people power over you.

Search hybrid inverter and rack mount batteries.

The memory makers will not expand demand drastically. It is in the nature of their business to keep the market under-supplied, otherwise the following oversupply will kill them. Instead, supply is just rerouted from less profitable segments such as mobile and personal computing.

> Of course, like literally every other time this has played out in computing history, the companies focused on price performance will end up with more economic resources, and get to turn the upgrade crank more often and for longer.

The iphone is the best selling computing device in history and is among the most expensive in its category.

Photonics used in AI is different to what you would expect. I can't see photonics replace the transistor and VLSI stack of computers. For networking however, high bandwidth photonics is well on its way to replace copper.

> Potholes are a visible manifestation of society saying it's more efficient to prioritize capital than care.

How though. Roads are a public good and fixing them should come from the governments pocket. How can you say the problem is private industry, when the government is doing such a good job collecting our tax money. You should be asking where is that money going. And then you will see its because of mismanagement by the government. Trillions in debt, for what?

Potholes are a visible manifestation of society saying it's better to vote for people who vibe with you, than people who can provide essential services.

No, burning models into hardware won't make them faster or reduce the cost. It will cost way more for similar performance as what you would get with a gpu. I am not telling you why, you can go figure that out on your own.

> The fact that these high prices are caused by an actual lack of resources and that the higher prices are driving a reallocation of resources to those who need them most (ie. most willing to pay for them) is not on the radar for many

Careful using words like "need". The resources are allocated to the economically most efficient sectors. Since if you are economically efficient, your profits are higher and can afford to pay more than others.

Which is absurd, since all the technology he used was manufactured by the conventionally powerful forces and they can decide to not sell you their stuff.

These small proxy wars are irrelevant. Scrappy drones are only used because that is all these small countries can produce. For superpowers, the goal isn't to stockpile mediocre equipment; it is to develop intellectual capabilities. During wartime, manufacturing can then be rapidly ramped up. You cannot invent and develop advanced tech overnight, but you can rapidly scale production.

Also fighter jets are capable of doing so much more than fpv drones, its actually funny that people think drones are the future.

In China, engineers hold the most power, yet the country prospers. I don't think the problem is giving engineers power, rather a cultural thing. In china there is a general feeling of contributing towards the society, in the US everyone is trying to screw over each-other, for political or monetary reasons.

The mathematically correct way to distribute the winnings is 50-50. In a situation where value is created only if 2 entities come together, the only fair way to distribute the winnings is 50-50. If Alice provided $1m dollars of startup capital, but can only achieve her goal having Bob on the team. Mathematically, Bob should be entitled to half the profits. In your game Bob is clearly being disadvantaged. Real life doesn't typically have the constraint "In addition, they have no ability to communicate or negotiate the offer; it's a one and done thing". Without this constraint, Bob can act rationally by threatening and following through with spitefulness in order to negotiate better terms. If Alice is not willing to negotiate until the fairness mark is reached, they are just as liable for the net loss in value.

There is a difference between learning about things that you find interesting at your own pace, and learning about things that interest other people with tight deadlines. Even if I enjoy learning, there were absolutely courses that were just a waste of time.
