  • 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’s not, though. The classical factors of production, whence we get the concept of “capital” as a factor of production, has land and capital as clearly separate:

    Land or natural resource — naturally occurring goods like water, air, soil, minerals, flora, fauna and climate that are used in the creation of products. The payment given to a landowner is rent, loyalties, commission and goodwill.

    Labor — human effort used in production which also includes technical and marketing expertise. The payment for someone else’s labor and all income received from one’s own labor is wages. Labor can also be classified as the physical and mental contribution of an employee to the production of the good(s).

    Capital stock — human-made goods which are used in the production of other goods. These include machinery, tools, and buildings. They are of two types, fixed and working. Fixed are one time investments like machines, tools and working consists of liquid cash or money in hand and raw material.

    https://en.m.wikipedia.org/wiki/Factors_of_production

    And it’s an important distinction. The fact that land is not made and inherently finite makes it zero-sum. Meanwhile, the fact that capital such as education, tools, factories, infrastructure, etc. are man-made and not inherently finite makes them not zero-sum. This distinction has truly massive implications when it comes to economics and policymaking. It’s the whole reason LVT is so effective, so efficient, and so fair: it exploits the unique zero-sum nature of land.




  • Property taxes != Land value taxes

    Further, it’s not a tax on capital; it’s a tax on land. It’s very explicitly designed to target land, as land has distinct economic properties that make it a prime target for taxation.

    And yes, it does target speculative investments like those of Blackrock:

    It reveals that much of the anticipated future tax obligations appear to have been already capitalised into lower land prices. Additionally, the tax transition may have also deterred speculative buyers from the housing market, adding even further to the recent pattern of low and stable property prices in the Territory. Because of the price effect of the land tax, a typical new home buyer in the Territory will save between $1,000 and $2,200 per year on mortgage repayments.

  • They are taxed, but I think they could be taxed more and better. Specifically, we should implement a land value tax (LVT).

    As for why LVT? In short, it’s just a really good tax. Progressive, widely regarded by economists as “the perfect tax”, incentivizes efficient use of land, discourages speculation and rent-seeking, economically efficient, and hard to evade. Plus, critically regarding landlords, land value taxes can’t be passed on to tenants, both in economic theory and in observed practice.

    As for the difference between LVT and property taxes? This video explains well how property taxes enable land speculation and disincentivize housing development, and how replacing them with land value taxes would alleviate these issues.

    Further, even places (such as the Australian Capital Territory) that have implemented quite milquetoast LVTs have seen positive impacts on housing affordability:

    It reveals that much of the anticipated future tax obligations appear to have been already capitalised into lower land prices. Additionally, the tax transition may have also deterred speculative buyers from the housing market, adding even further to the recent pattern of low and stable property prices in the Territory.

  • Sounds similar to some of the research my sister has done in her PhD so far. As I understand, she had a bunch of snapshots of proteins from a cryo electron microscope, but these snapshots are 2D. She used ML to construct 3D shapes of different types of proteins. And finding the shape of a protein is important because the shape defines the function. It’s crazy stuff that would be ludicrously difficult and time-consuming to try to do manually.

    This is so true for the housing crisis. Conservative NIMBYs will be like “deregulation good!” and “free market good!”, but then they religiously show up to any and all city hall meetings to rant and rave about how we need to use heavy-handed regulations to protect “historic” parking lots and the “neighborhood character”.




  • I moved from California to Montreal a few years back to study, and now I’m staying for good. I tried duolingo on and off for far too long, but I found it super uninteresting and hard to remain committed to.

    Best strategy I’ve found is called comprehensible input. The idea is to find books or other reading material that you can get the basic gist of when reading, despite not understanding every single word and phrase and grammatical construction. The more you read, the more you’ll find yourself able to understand, which is also very motivsting!

    Also, make sure it’s material that actually interests you. The idea is it’s better to read extensively, reading things that actually interest you to some degree and keep you mentally engaged, than to just really intensively study a much smaller amount of (less interesting) material.

    This actually mirrors how we acquire languge. The idea is to intuitively understand French by having seen a lot of it rather than to basically memorize French. You ultimately want to be able to glance at a sign, for instance, and just know what it means without having to translate in your head.

    Some resources I found useful were these French illustrated books in Dollarama, but even better is a series of books designed to be comprehensible input by Olly Richards. He’s a native English speaker and polyglot who has written a bunch of graded readers that gradually increase in vocabulary and difficulty. He has several books for French, including beginner short stories, intermediate short stories, beginner conversations, intermediate conversations, climate change, WW2, and philosophy. The nice thing is he actually does a good job of making the stories and content interesting to an adult learner, unlike the children’s books at Dollarama.

    Even his beginner books might be a little too advanced for your level so far, though, from what you say. If they are, it’d be best to find some material at a lower level that you can understand a little better. After all, if it’s too hard for you, it will make the process much slower and less enjoyable, which will make it much more likely that you quit. You could even simply try googling “french comprehensible input” to try to find material suitable for your level.

    One last resource is the government of Quebec offers free in-person courses for immigrants and many French learners. They are part-time, and they offer multiple options for hours per week, so you could pick what works best for you. It would be worth checking to see if you might qualify for those courses once you move here.



  • taxing the shit out of third homes for example

    There’s actually a far more elegant type of tax that would have the effect you desire: land value tax.

    In short, it’s a progressive, difficult-to-evade, and extremely economically efficient tax that – both in economic theory and in observed practice – cannot be passed on to tenants. Further, it strongly incentivizes new housing development, heavily penalizes real estate and land speculation, and improves affordability. In fact, it’s so well-regarded a tax that it’s been referred to as the “perfect tax”, and is supported by economists of all ideological stripes, from free-market libertarians like Milton Friedman – who famously described it as the “least bad tax” – to social democrats and Keynesians like Joseph Stiglitz. It’s simply a really good policy that I don’t think is talked about nearly enough.

    Even a quite milquetoast land value tax, such as in the Australian Capital Territory, has been shown to reduce speculation and improve affordability:

    It reveals that much of the anticipated future tax obligations appear to have been already capitalised into lower land prices. Additionally, the tax transition may have also deterred speculative buyers from the housing market, adding even further to the recent pattern of low and stable property prices in the Territory. Because of the price effect of the land tax, a typical new home buyer in the Territory will save between $1,000 and $2,200 per year on mortgage repayments.


  • Then tax land. Make landlords sweat if they fail to rent out units.

    The solution to housing affordability is all about negotiation power. Currently, tenants in many cities do not have negotiating power because an overall shortage of housing and thus no credible threat of vacancy (and with no land tax, vacancy isn’t enough of a financial loss). Build more housing by making it legal and easy to build housing, tax land, and tenants will have far more negotiating power.

    A good example is my city, Montreal. Thanks to being one of the most YIMBY cities in North America, we have far more missing middle housing than any other city of this size on the continent. The result? More power to the tenants, less to the landlords. And the result of this power? Not only is my rent waaaaay cheaper for what I get compared to my sister in Boston (we pay about the same, but she has 3 roommates and lives farther out, while I have 1-br and live right next to downtown in an insanely walkable neighborhood), but I also negotiated down my rent when moving in. The reason I could negotiate down my rent was because the landlord had a credible threat of vacancy, so they’d rather lower rent by a hundred bucks than risk vacancy.


  • The urban area is what people refer to as Paris. A good comparison is Los Angeles. Lots of people say they “live in LA” but in fact live in Santa Monica or Long Beach or Pasadena or any of a million other suburbs that together form the Los Angeles urban area.

    When people say they live in Paris, 99% of the time they’re not talking about the arbitrary municipal boundaries; they’re talking about the urban area.

    When people say they live in LA, 99% of the time they’re talking about the urban area.

    When people say they live in Buenos Aires, 99% of the time they’re talking about the urban area.

    When people say they live in Tokyo, 99% of the time they’re talking about the urban area.

    “Urban area” is simply a term meant to capture what people mean when they refer to a city, unrestricted by the arbitrariness of municipal boundaries.
