  • Silvopasture is an ancient practice that integrates trees and pasture into a single system for raising livestock. Pastures with trees sequester five to 10 times as much carbon as those of the same size that are treeless while maintaining or increasing productivity and providing a suite of additional benefits. Livestock continue to emit the greenhouse gases methane and nitrous oxide, but these are more than offset by carbon sequestration, at least until soil carbon saturation is achieved.

    Silvopasture also offer financial benefits for farmers and ranchers. Livestock, trees, and other forest products, such as nuts, fruit, and mushrooms, generate income on different time horizons. And help protect farmers from risk. The health and productivity of both animals and the land improve.

    Trees in silvopasture systems provide livestock with protection from sun and wind, which can increase animal comfort and improve production. Trees can provide shade in the summer and windbreaks in the winter, allowing livestock to moderate their own temperature. Heat stress in livestock has been associated with decreased feed intake, increased water intake, and negative effects on production, reproductive health, milk yields, fitness, and longevity.[4][5]

    Certain tree types can also serve as fodder for livestock. Trees may produce fruit or nuts that can be eaten by livestock while still on the tree or after they have fallen. The leaves of trees may serve as forage as well, and silvopasture managers can utilize trees as forage by felling the tree so that it can be eaten by livestock, or by using coppicing or pollarding to encourage leaf growth where it is accessible to livestock.[1]

    Well-managed silvopasture systems can produce as much forage as open-pasture systems under favorable circumstances. Silvopasture systems have also been observed to produce forage of higher nutritive quality than non-silvopasture forage under certain conditions. Increased forage availability has been observed in silvopasture systems compared to open-pasture systems under drought conditions, where the combination of shade from trees and water uptake from tree roots may reduce drought impacts.[1]

  • The raison d’être for RISC-V is domain-specific architecture. Currently, computational demands are growing exponentially (especially with AI), but Moore’s Law is ending, which means we can no longer meet our computational demands by scaling single-core speed on general-purpose CPUs. Instead, we are needing to create custom architectures for handling particular computational loads to eke out more performance. Things like NPUs, TPUs, etc.

    The trouble is designing and producing these domain-specific architectures is expensive af, especially given the closed-source nature of computer hardware at the moment. And all that time, effort, and money just to produce a niche chip used for a niche application? The economics don’t economic.

    But with an open ISA like RISC-V, it’s both possible and legal to do things like create an open-source chip design and put it on GitHub. In fact, several of those exist already. This significantly lowers the costs of designing domain-specific architectures, as you can now just fork an existing chip and make some domain-specific modifications/additions. A great example of this is PERCIVAL: Open-Source Posit RISC-V Core with Quire Capability. You could clone their repo and spin up their custom RISC-V posit chip on an FPGA today if you wanted to.

    It also had a second rule set where a land value tax was implemented, and the winning condition was when everyone made a minimum amount of money.

    A land value tax (LVT) is a levy on the value of land without regard to buildings, personal property and other improvements upon it.[1] It is also known as a location value tax, a point valuation tax, a site valuation tax, split rate tax, or a site-value rating.

    Some economists favor LVT, arguing it does not cause economic inefficiency, and helps reduce economic inequality.[2] A land value tax is a progressive tax, in that the tax burden falls on land owners, because land ownership is correlated with wealth and income.[3][4] The land value tax has been referred to as “the perfect tax” and the economic efficiency of a land value tax has been accepted since the eighteenth century.[1][5][6] Economists since Adam Smith and David Ricardo have advocated this tax because it does not hurt economic activity, and encourages development without subsidies.

    LVT is associated with Henry George, whose ideology became known as Georgism. George argued that taxing the land value is the most logical source of public revenue because the supply of land is fixed and because public infrastructure improvements would be reflected in (and thus paid for by) increased land values.[7]

    It’s just a stupidly good tax policy, and we should be implementing it in more places.

  • NYC itself doesn’t have much (although it still has some! see image below) low-density zoning, but their suburbs sure do. The city itself also has a lot of other bureaucratic barriers to development that result in it having abysmal housing construction rates.

    As for vacancy, yes, the threat of not being able to sell is what stops builders from building too much. For example, it’s the reason no one’s even trying to build the Burj Khalifa in Bakersfield. But if you make it legal and reasonably easy to build, yes, people will build.

    Perhaps Tokyo is the best example. Biggest city in the world, and yet it’s actually relatively affordable, thanks largely to good land use policy:

    In the past half century, by investing in transit and allowing development, the city has added more housing units than the total number of units in New York City. It has remained affordable by becoming the world’s largest city. It has become the world’s largest city by remaining affordable.

    Two full-time workers earning Tokyo’s minimum wage can comfortably afford the average rent for a two-bedroom apartment in six of the city’s 23 wards. By contrast, two people working minimum-wage jobs cannot afford the average rent for a two-bedroom apartment in any of the 23 counties in the New York metropolitan area.

    In Tokyo, by contrast, there is little public or subsidized housing. Instead, the government has focused on making it easy for developers to build. A national zoning law, for example, sharply limits the ability of local governments to impede development. Instead of allowing the people who live in a neighborhood to prevent others from living there, Japan has shifted decision-making to the representatives of the entire population, allowing a better balance between the interests of current residents and of everyone who might live in that place. Small apartment buildings can be built almost anywhere, and larger structures are allowed on a vast majority of urban land. Even in areas designated for offices, homes are permitted. After Tokyo’s office market crashed in the 1990s, developers started building apartments on land they had purchased for office buildings.

    I think the key idea is to not have government bureaucrats or existing homeowners or landlords decide whether there’s “enough” housing, but rather let builders determine if there’s unmet demand. If there is unmet demand, they will build if you let them. If there truly is enough housing in a certain city, then you don’t need to tell builders not to build – they’ll simply stop building if they sense there’s not enough demand for it.


  • The “we have enough homes already” is a common (and unfortunately very harmful) myth.

    A couple good in-depth videos on the topic:

    The gist of it is that statistics on how many vacant homes exist are highly misleading, for two main reasons:

    1. Many of the homes are not where the demand is. A vacant home in St Louis does nothing to help with a housing shortage in NYC. People want to live in NYC because that’s where the jobs are. A house in St Louis isn’t worth much if you can’t find work there. And statistics consistently show that the most expensive cities have the lowest vacancy rates.
    2. A lot of the homes that are counted as “vacant” aren’t actually just free for the taking like “vacant” would have you believe. In these statistics, “vacant” can mean: 1) a unit that is between tenants, 2) a unit that just finished being built and is awaiting its tenant’s move-in, 3) a unit occupied by someone who doesn’t legally state it as their primary residence (e.g., student housing where the student still lists their parents’ home as their primary address), 4) a unit in horrible disrepair that is unfit for occupation, etc.

    Add to this the fact that high vacancy rates are GOOD for you, as it means landlords and sellers have a credible threat of vacancy, meaning they can’t demand ludicrous prices. Reducing vacancy rates is an incredibly anti-consumer, pro-landlord move.


  • Yeah, political opinions based on “regulations always good” or “regulations always bad” are lazy and unhelpful. For one, it ignores that many regulations are written for the express purpose of manufacturing or solidifying a monopoly.

    Regulatory capture

    And NIMBY land use policies really are just a textbook example of regulatory capture. Homeowners, who expect their homes to perpetually increase in value, lobby their local governments to manufacture an artificial scarcity of housing so as to drive their property values to the moon. All of this at the expense of renters and new home buyers.

    Imo, we should all be trying to form nuanced political opinions where we judge policy on whether it’s good policy or not.



  • Exactly. When the accused has paid off half the jury, you shouldn’t put much stock in the verdict.

    The only thing I care about when determining whether something is a genocide is the facts of the case (which are overwhelmingly in favor of describing the Uyghur genocide as a genocide), not the outcome of a highly political vote by countries all with their own motives and interests.
