> That goes well beyond simply making sure that people are able to care for themselves.

I am not sure in understand the issue, if Japanese want this, what’s the problem?


Just because some people want something that doesn't suddenly make it reasonable or wise. In this case it's a problem for many already successful people living in Japan currently who will be forced to leave. It's also a problem for Japanese companies who have hired those people or who want to attract foreign talent to positions that pay well, but don't typically leave someone fabulously wealthy compared to most of the people living around them. It's also a problem because the policy is coming in at a time of increased xenophobia and overt racism and while this policy is likely to reduce the total number of foreigners living in Japan, it's unlikely to address the problems people have with the foreigners who will remain, and it could actually make those problems worse.


It's their country. They can do what they want as long as they don't start another war.


I don't think anyone plans on trying to step in and intervene, but I hope people also don't shy from talking about how foolish this move is, the problems it won't solve, the problems it's likely to cause, and the people whose lives are being negatively impacted by it.


Why don't you trust the Japanese to know wha they're doing when it comes to their own society? After all, they're the ones who built an amazing country everyone wants to visit!


Because the yen is weak is a big reason why visiting is appealing. Its also a big reason why their population is dwindling.

The govt is just trying to point fingers at foreigners to hide their weakness. I think recently they made a big deal about foreign owned real estate then quickly forgot about that talking point when their own study showed it equated to something like .05% of their total housing.


That’s not the point I’m making. Japan is clearly a wonderful society, seeing as how many people want to visit and immigrate. Why not trust the people who built that society that they know what they’re doing?


> Japan is clearly a wonderful society

I don't think so.

> seeing as how many people want to visit and immigrate.

That's true for Qatar and UAE too. Wonderful societies.


If you think this is true then you simply lack the creativity to understand how bad domestic laws can get.


you're on a discussion forum. The point is to discuss things. Why are you being such a scold about what we're allowed to talk about.


Something must be done, this is something, we must do it!

Just because something can be done doesn't make it good for the society. Japan has a shrinking population and is currently dependent on immigrants for low wage work. Plenty of actions can make the current problem worse and have unintended consequences. Whether they happen or not is a political question, not a moral one.

Who determined "what they want?" Did you want your government to attack Iran? Are you responsible for it? Why not?


> Just because something can be done doesn't make it good for the society.

In this case the consequences will make people to elect a better government next time and try better ideas. Democracy at work.


That's their problem to solve however they want, if they want. The population shrinking by some large percentage doesn't seem to be inherently bad to me, and probably is good.

It's so laughable to me when people say "BUT THE SHAREHOLDER VALUE!" when we talk about things like the important life trends of millions of people.


For Japan, shrinking population will mean an aging population with no one to care for them.


Not if we have robots and AI.


[dead]

> A people can recover from that, though

Absolutely. They’ll just go through a period of a bunch of social workers discovering a new corpse every three days. Whole towns dying because there is nobody to maintain the public services. The people will get exactly what they were asking for, and they’ll die for it.


>and they’ll die for it

I've yet to meet people immune from the inevitability of death, via the immigration policies of their country.

What exactly was your argument here? Because I'm not seeing the downside in what you wrote.



A few generations ago they were enslaving people [0]. This is what racism can lead to. Maintaining their heritage, their way of life, some would say.

Hopefully their population decline doesn't hit them too hard. But that, and their lack natural of resources, could lead to bad things. Fascists and their ilk thrive in such situations.

> I am not sure in understand the issue, if Japanese want this, what’s the problem?

The problem is I’ve built my life here and they keep treating foreigners as a lesser life form. People here can unironically be standing next to me bitching about foreigners. Then turn to me and say something like “not you, you are fine.”


Clearly Japanese feel like they don't want immigrants or want very few of them, which is fine.

With these laws, they are pushing 99% of people out while saving face from being called racists.

I think every country should have a right over their borders. Japan wasn't built on multiculturalism like United States or Canada, so I'm not surprised.

That being said, I would probably think twice about traveling to Japan as a tourist.


I disagree, it's not fine.


United States wasn't exactly built on multiculturalism either.

Laws dating back to 1790 restricted naturalization to white people, which arguably makes the US a sort of white ethnostate from the very beginning. This stuff only really went away after the 1965 Hart-Celler Act, and repealing that act appears to be an objective of the american right wing as of 2026.

It really made me question whether it was possible for a third worlder like me to ever become an american.


Plenty of foreigners are in fact quite rude towards their new hosts though. It can and does bring out the worst in people, and I can't say I blame them.

The whole idea of naturalization is to assimilate into the new culture and become one of them. Far too many people just don't put in the effort to do that.


That's the risk you run immigrating to another country.

I immigrated to another country and I went in eyes wide open knowing that at any point I might have to pack up and head home. In fact, it became far harder to immigrate only a few years after I did. Likelihood is that if I hadn't come when I did I never would have been able to.

It took 10 years to finally become a citizen, but I did so the first day it was an option (yes, I counted down the days and sent in the application on day 1), because I knew it was the only way I could safely assume I'd never be forced to leave.


You are a guest in a home that belongs to others. You're not entitled to their indefinite hospitality


We’re not allowed to have opinions?


It would be fine if it was a well documented recurring issue that plagued society. As is it, it feels more like a canary in the coal mine, for dirtier times to come.

In practice, most visas are short term, and none of them will allow you to benefit from social aids for very long. At most I imagine you could extend your working visa to 5 years, get sick the first year and be at charge for the remaining 4 years ? There will be ink spent on these cases, but statistically how often does that even happen to need stricter laws ?

The current political climates needs the gov to look "Japan First" and these kind of rule change are very cheap to do, especially as the people directly impacted don't vote nor can complain. It goes well with the very anti-foreigner sentiment, especially as the current wave of tourists is very unpopular despite the money coming in.

The longer view is Japan getting less workers in total, yet more of the worse immigrants as they're calling for people who either don't need Japan (have enough money to go anywhere and don't need to think long term) or are willing to take more risks (high return grifts etc.), in a time where Japanese salaries and productivity are already lower than surrounding countries.

They're basically making a bad situation worse, just for short term political play, giving in on the worse trends.


[flagged]

There is nothing cruel about it. Nobody has been forced to go and live in Japan.


telling a person that has build a successful life after eight years, is assimilated and speaks the language and can support themselves that they have to leave on completely absurd conditions that virtually nobody could meet, including native citizens, is cruel by just about every definition of that term.

Those people have only ever paid in, have much better options than Japan at this point economically given how far the country has fallen behind, and the logical terminus of this is basically being some kind of ethnic chauvinist second world clown country.

If you're even turning skilled tech workers and law abiding people away your immigration problem is solved by virtue of being poor in another 10-20 years. Japan fell below replacement fertility in the 70s, 35% of the population is over 60, good luck caring for those tens of millions of people about to retire.


    > they have to leave
No one is forcing them to leave. They can continue to live and work in Japan on their current visa, and renew it. Japan is simply raising the requirements for permanent residence using the traditional ten year path. To be clear, there are numerous paths to permanent residence that are much easier than the traditional ten year path. (Your favourite LLM can tell you all about it.)

    > completely absurd conditions
The new requirements are not this. In short: (1) modest Japanese language requirements, (2) more pension (or personal) savings, (3) higher salary.

    > If you're even turning skilled tech workers ... away
They are not. As I understand, Japan does not limit the number of skilled visas, such as engineer, humanities, or manager. Also, many of those foreign tech workers will make more than 10M JPY per year and can easily qualify for something called the "Highly Skilled Professional" (HSP) visa. Depending upon your "HSP points", you can get permanent residence after one or three years without any of the other requirements.

The real issue is the people who have lived and worked in Japan for a long time, but don't earn large salaries. Japan is basically closing the door for permanent residence for those people unless they marry a local. My hot take: I am OK with closing the door for those people. They are basically earning a lower middle income. I'm not sure Japan wants or needs to have those people as permanent residents. However, they are free to live and work here as long as as they want. After they finish working, they can return to their home country. No one is taking that away.

    > good luck caring for those tens of millions of people about to retire.
They will do it by expanding their existing (enormous) technical intern programme. There are already many low(er) skill foreigners working in elderly care.


> No one is forcing them to leave. They can continue to live and work in Japan on their current visa, and renew it.

Totally wrong, people who were eligible for the business manager visa are no longer elgibile with zero warning or grace period granted, so yeah, total BS. If you built a business here, that's been destroyed if you don't have enough money to quality for another business manager visa under the new (ridiculous) requirements.

What about the people who have worked for 10 years , paid all their tax, not broken the law, but don't have 30 years worth of money to live on, do you think they should be rewarded with the rejection of a PR? On what grounds is that fair?

I get the feeling you either have zero connection to Japan, or you do live here and are married to a Japanese, so you're happy to see the ladder get pulled up because "you're ok".


    > people who were eligible for the business manager visa are no longer elgibile with zero warning or grace period granted
To be clear, they can continue to run their business for the duration of their visa. It is not an immediate order to leave the country. That is a false statement.

You are right that a significant change was made to the business manager visa. Old rules: 5M JPY was required as "minimum capital". New rules: 30M JPY is required. The primary reason for the change was to close a loophole that many mainland Chinese used to get a business manager visa to move their family to Japan. (There is no group of people less liked by Japanese people.)

I agree: They should have added a carve-out for legitimate small businesses. Alternatively, they should have created a programme to lend money at a reasonable interest rate and X years to become compliant. There are many non-Japanese restaurants that are run by first generation immigrants from South Asia, Southeast Asia, and East Asia. However, the actual number of small businesses that have been "forced to leave" as a result of this change are as yet unknown.

There were a few very noisy folks that the mainstream media reported about over and over. However, they should try to borrow money from friends, family, or a bank. Personally, I contacted one of them via WhatsApp to offer to lend money to make the 30M JPY requirement, but I never heard back. After that, I assumed that they were "blowing smoke" (bullshit). Interestingly, for all the ones that were very publicly complaining about the changes (that I saw), none of their businesses have closed. I guess they made it work.

    > 30 years worth of money to live on
I won't repeat myself here, but I answered that concern here: https://news.ycombinator.com/item?id=49864179

The financial situation of the Japan central gov't is the same or worse compared to ten years ago. They don't want to grant permanent residence to people who are less than middle class. It is very likely that these people would consume in public benefits during retirement far more than they ever paid into the system. I think Japan is being financial prudent about what foreigners they allow to "stay forever". So, yes, I agree: They "pulled up the ladder", economically speaking.

Another myth of the traditional (my term) ten year permanent residence route: It is not guaranteed to be granted even if you followed all of the known and public rules -- good salary, paid all taxes (incl social), no traffic violations/arrests, etc. They look at your integration into Japanese society. If your Japanese language is poor, they frequently reject. If you are unmarried, they also frequently reject. If you belong to no civic orgs or never volunteer, they also frequently reject. If you don't have multiple personal recommendations for PR from Japanese citizens and/or other PRs, they also frequently reject. There are many, many Reddit and blog posts about such rejections.

Finally, have these changes affected you? You seem very emotionally charged in your posts about the matter.


I agree, but unfortunately, looking at the news from Japan, far-right support rates are higher than one might expect.

So it's true that those in power are harming innocent people in order to maintain their power, but it's also true that Japanese people believe they are being harmed by foreign immigrants.

And some of it is actually true. Of course, conversely, there's also the problem of many Japanese companies hiring Southeast Asian workers at low wages and mistreating them.

But whether it's me as a Korean or Japan, both tend to have a certain authoritarian mindset instilled based on "ethnic" identity. So one aspect of this policy is "we only welcome rich foreigners who spend money and leave," and the media responds accordingly.

Strictly speaking, if you look at these policies strengthening restrictions on foreigners from a third-country perspective, you can see them from the angle of far-rightization. That is, sanctions against outsiders for the sake of internal cohesion[1]. But considering the severe aging population in Japanese industry right now, it's effectively cutting off one's own nose to spite one's face.

However, East Asians receive a somewhat different education from you, so that's how it is.

The real cause is the failure of Abenomics and the resulting weak yen, which benefits financial companies and exports but sacrifices the Japanese people—the incompetence of the regime is the problem. But because it's hard to grasp all of that complex background, people want to attack something else that's near them.

And also, because the morality of some underdeveloped countries (I know it's an example...) differs from that of developed countries, friction often occurs. Just as the sense of time differs between agricultural regions and cities, for instance.

  > The real cause is the failure of Abenomics and the resulting weak yen
i think you are right, there is a lot of over-tourism (and from some places 'rude' tourists that are really aggravating to people) but that is also being caused by weak yen in the end...

whats the saying? everything is downstream from economics?


> ACA?

How’s ACA hard-hitting on corporations?

The 15/20 rules is what resulted in recorder profits in health insurance business, how’s this anti-corporate?


> How’s ACA hard-hitting on corporations?

"You must sell insurance to sick people!", "I don't wanna!", "I don't care, the law now says you must."

I mean, the whole insurance industry had spent the better part of a century (basically its whole existence) denying coverage to people with pre-existing conditions, and the ACA fixed it via fiat.

Not only is it clearly "hard-hitting", I'd argue it's probably the single most "hard-hitting" invasive change to corporate regulation of the post-war era. Certainly it is in terms of the amount of money involved in the affected market.

> how’s this anti-corporate?

And this is where the rub is. You're not saying that your desired regulatory structure is something different than existing proposals, you're demanding that your government engage in behavior that is expressly "anti" whatever you perceive "corporate" interests to be.

That's not democracy, that's just warfare. You have enemies and you want to win. And the problem there is that the structure of our government requires compromise.


ACA literally forced every person in the US to become a customer of health insurance companies.


It "literally" did not. What enforcement exists is financial (a tax penalty) and not compulsory. And obviously most people are covered via employer plans or Medicare, as has always been the case. A quick Google says that 19.2M Americans are enrolled in ACA plans. I don't have statistics, but I'd bet that the overwhelming majority of those are willing purchasers. Most people view health care as desirable.


The "everyone has access to the ER" has to be paid somehow, which is through tax dollars. The USA has a for-profit health system but typical neo-liberalism has a safety net where corporates get to dip into a different bottom-less pot. So it makes sense that we make this visible by taxing everybody who isn't paying their own insurance, since they still expect access to ER.


No, it didn't. If you didn't want to buy health insurance, you just had to pay a couple extra thousand in federal income tax:

https://landline.media/affordable-care-act-tax-penalties-end...

>The penalty for not having an ACA-compliant plan or forgoing coverage in 2018 is the greater of $695 per adult and $347.50 per child for a maximum of $2,085 or 2.5 percent of adjusted household income. The percentage penalty is capped at an amount equal to the national average premium for a bronze plan, the minimum coverage available by law


Ah yes, the very hard hitting anti-business rule that says if you don't become a customer of my friend's company, you must give me money. I'm sure the businesses were quivering in their boots when every citizen either became a customer, paid a fine, or became a felon.


Then why do the 7 publicly listed health insurers have shitty shareholder returns?

If their profits are so good, their shares would be worth owning.

Could it be because their profit margins are actually terrible (3% if lucky), and they have to get the price of their product approved by 50 different state government employees, and the federal government constantly changes their customer’s subsidies making revenue and expenses extremely volatile and difficult to forecast?


If you bought shares of those 7 companies in 2010 when the ACA passed, how much would you have today? More or less than if you bought the S&P 500?

If you're looking for policies to blame for insurance companies having a rough 2025-2026, look to the Republican-led efforts cap Medicare fees and alter eligibility requirements.


You would have about the same or less. Maybe UNH gets you a couple extra percentage points per year, but that's because they have an enormous healthcare provider business instead of just being an insurer. But it's still nowhere near a positive risk adjusted return when comparing to a relatively risk-less investment in SP500.

https://dqydj.com/sp-500-return-calculator/

https://dqydj.com/stock-return-calculator/

Since Jan 1, 2010, 18% for UNH, 15% for MOH/CNC, 14% for CI/ELV/HUM/SP500, 8.5% for CVS.

Also, these businesses are competing to sell a completely fungible commodity good with tons of non profits like Kaiser Permanente, HCSC, Cambia, Independence Blue Cross, and many others. It makes no sense to expect those businesses to be able to earn any decent profit margin when their competition only needs 0%.


> Then why do the 7 publicly listed health insurers have shitty shareholder returns?

CNC is up 90% YoY. That's far more than any of the largest tech companies. Alphabet is the highest of the tech stocks, and it's up 38% in the same period. When we look at the performance of the seven large U.S. publicly traded health insurers, their returns were extraordinary in the decade following the ACA.


HBM is a stack of DRAMs, so there is no “instead”.


The vias to enable stacking is a significant amount of the die area.


If they're talking about production capacity, that is some product of die area and process steps, right? It doesn't have to be 3x die area, just 3x lower factory throughput for the same number of functioning memory bits.


HBM is less dense at a water scale than DDR because of all the vias, but each memory but is as dense or denser.

You make HBM instead of DDR and the number of bits you're making goes down.

It's really that simple.


> They're still recording everywhere and sending a transcription to iCloud and they're doing it without consent.

Plenty of jurisdictions are single consent.

Moreover, what is the difference with using your phone to record?


> when it is in fact a well-documented and pretty mundane practice

Practiced by Apple? Just because someone is doing it doesn’t mean that every company does it.


Or an agency on their behalf, but either way, there's really no way for us to really know, due to the stealthy nature of this sort of advertising.


There is no factual accuracy at all, only speculation and empty claims.

Do you have a proof that Apple has bot farms to push its narrative?


I have no proof, only personal experience interacting with commenters on HN. No other tech company gets as much positive support when exerting its soft power under the guise of (bullshit) technicalities, e.g. all the issues with EU digital markets, API restrictions, 30% tax. Specifically, people were defending Apple vehemently when they feature gated remote phone control for EU citing concerns about EUs privacy laws (???).

I never stated that I know for a fact that Apple deploys bots, but I would not be surprised. I don’t even need to know if anyone is paid or not - if I cannot distinguish paid posts from fanatic apologism, then I need not care. The resulting posts are worrying all the same.

Similarly, I do not know if Apple was caught off guard by the demand - I wouldn’t trust this article. But Apple does plan production well ahead of time and forecast demand rather precisely. They could’ve been wrong. Them being unable to produce enough 1/2tb mac studios seems like a loss to me.


Do you have proof Apple is facing unexpected demand for the Mac Mini because of AI? Do these news sites?


I am not the one making claims here.

You can’t claim A, and then when someone asks you for a proof reply with “prove that it’s not A”.


Interesting that Samsung still pursues PIM. IIRC they had a paper in ISCA21 or 22 where they showed HBM2 module with PIM, which back then impressed me quite a lot.

That being said, I am not sure what’s the killer application for this technology, and without such application adoption is unlikely.


As I understand it, the killer app is llms. You could run MACs directly in RAM, offloading a lot of work from CPU and cutting down on insane (external) memory bandwidth required.

Imagine (this is a fantasy pitch but potentially achievable for some use cases) wanting to run a larger llm and all you have to do is buy more RAM so it fits.


> You could run MACs directly in RAM

Sure, MACs are nice. However, unless there other, PIM-specific/optimal, algorithms, regular matrix multiplication algorithms like tiling-based won’t work here I think — how would the tile be shared? By doing read/write all the time?


Attention calculations aren't shared across more than one vector during next token prediction (thinking and writing) which this sounds almost perfect for. Per attention layer, for deepseek at 1M context, you want to broadcast a single 1KB vector to 4GB of dot products, and map reduce a 1KB vector back.


How exactly the map-reduce will happen though? Won’t you need to do it host-side, or make a lot of reads and writes?

Also, doesn’t it mean that you forgo batching?


Map-reduce is implemented as a rolling calc, see: online softmax in FlashAttention kernels.


Rollie calculation, like the online softmax in FA, implies a centralized computing unit that does the compute and stores the intermediate results in its registers. With PIM you have no centralized compute unit, you have a bunch of memory, and a bunch of MACs all over the place.

How would you do map-reduce across multiple DIMMs w/o extra reads/writes?

PIM implies some sort of distributed compute, which can work for some cases, but I am not sure LLMs are one of them.


Is there a single reason why we can't just "distribute" the online softmax?

Each die-attached PIM accelerator computes online softmax for its own KVs. Then the central unit gathers the softmax intermediates, one intermediate per die, and uses those to compute the final softmax.

The PIM win is that we crater the memory traffic between the central accelerator and the memory dies for attention ops. Most of the attention bandwidth never leaves the memory.

This isn't "run the entire LLM in PIM", no - this is "offload the parts of LLM that benefit from PIM the most to PIM".


Re-arrange x+(y+(z+w)) into (x+y)+(z+w) to accomplish a distributed sum. Shared bus, interconnect fabric. This is a supercomputer on a chip.


> Imagine (this is a fantasy pitch but potentially achievable for some use cases) wanting to run a larger llm and all you have to do is buy more RAM so it fits.

Isn't this how it works today already? Granted you wanted to run it on RAM rather than VRAM.


Yes, but running out of RAM is impractical due to low memory bandwidth.

According to the article/Samsung RAM dies inside can support way higher bandwidth than they expose, they're limited by external interface / bus width:

> Together, they can utilize the chip’s internal bandwidth across all 16 banks, which comes out to 614 GB/s. For comparison, regular DRAM accesses can hit two banks in parallel and max out at 76.8 GB/s.

And that's just for single 64-bit IC. So way faster and more power efficient.


You can scale with more memory channels. Workstation/server platforms go up to 12 or 16 channels if I remember correctly.

Consumer platforms have been stuck at dual channel for decades; most of it I attribute to intentional product segmentation. I'm hoping that LLMs might change eventually for an upcoming consumer platforms; going to 4 channel would be really nice.


How do you scale past 16 channels though? 16 channels give you around 614 GB/s, while PIM can do that per chip, so it can achieve 58TB/s.


You: "AI, please write me $COOL_APP."

AI: "Sorry, all the hardware is made for running AI."


We can run Doom on everything. Surely we can run some interesting apps on hardware that's originally made for AI. (One big moment for AI was when people figured out how to run it on hardware originally meant for Doom's successors.)


The idea is this:

You have an eight socket server with 96 memory slots, you add 96x PIM memories into the server (optimistic), load all the LLM parameters or KV cache in RAM and exclusively let it perform GEMV and let it rip.

614 GB/s x 96 = 58,944 GB/s.

Alternatively, the memory is used for embedded inference tasks. You can now upgrade from the limited single or two digit MB SRAM accelerators to reasonably fast single digit gigabyte models. Without MoE you could reach 100 tokens per second with an 8B fp8 model on a single channel. With MoE you might break 500 tokens per second.


> load all the LLM parameters or KV cache in RAM and exclusively let it perform GEMV and let it rip.

Won’t you have a bunch of extra reads/writes via the CPU because these DIMMs won’t be able to compute matrix multiplications?


And now the 96 memory slots need individual cooling.


Which might be easier since the surface is larger


> That being said, I am not sure what's the killer application for this technology...

Build it, and they will come ;)


I am not sure a vote of non-confidence would have helped here — there are only two parties.


> I am not sure a vote of non-confidence would have helped here — there are only two parties.

But why are there only two parties?

The rest of the Anglosphere–Australia, Canada, Ireland, New Zealand, the UK–have multiparty systems–some are more multiparty than others, but none of them have the hard two-party system that the US has, in which third parties have a very marginal role (not completely marginal – e.g. in a close election, the decisions of New York's Conservative and Working Families parties can make a real difference to the outcome – but certainly at a national level third parties have no real power in the US.)

First-past-the-post is a popular explanation, but it can't by itself explain it, since the UK and Canada use it, yet lack a US-style hard two party system (and with the rise of the Reform party in the UK, the British system is becoming less two-party than it has been in a long time.)


Even if first-past-the-post could change, it's not the whole ballgame. To get on a state ballot you need thousands of petition signatures, and those signatures can be invalidated on technicalities brought up by major parties' legal teams. To be covered by the media or be included in a debate you need to poll at a high percentage. You can't get public funding to campaign unless you already had a high percentage of the vote in a previous election. Nobody will donate to you because the third party just detracts from the other two that will give the big donors what they want. And gerrymandering ensures the same people keep getting elected. All those roadblocks are in place because the two major parties put them there to prevent 3rd party challengers. The whole thing is rigged.

Just to show up and get 1% of the vote, you would need a grassroots national movement to elect someone who was wildly popular, who could build a 50-state network of volunteers (including legal, political, financial, community organizing, etc), sponsored by someone with extremely deep pockets that doesn't want anything from established political figures. And you'd still lose.

We have representatives already. The problem is we never hold their feet to the fire. We keep voting for the same useless bastards, and we don't vote them out when they do nothing. Half the country doesn't vote. That's our own responsibility we're shirking. Rather than get a new party, we need to get off our collective asses, and use the existing power we have to force the parties to do their jobs.


First past the post doesn’t explain historically why we have only two parties, but it explains why we will continue to have only two going forward unless something changes.


I actually think the US hard two party system isn't purely due to first-past-the-post, it is actually due to four interacting factors: (1) first-past-the-post; (2) presidentialism; (3) a deeply-entrenched primary system; (4) cultural homogeneity

Point (4) will likely strike many Americans as dubious, but the US doesn't have anything comparable to Québec – there is presently no US state where English isn't the majority language; nor anything comparable to Scotland or Northern Ireland (no state where a significant percentage of its population identify with a competing national identity). So, no matter how much (undeniable) diversity the US has, in the sense that counts for this purpose, it doesn't.

Hence: while abolishing first-past-the-post would no doubt do a lot to break the US hard two-party system, it could also be broken while retaining it if something happened to (2) or (3) or (4) instead.

But, in US politics, changing (2) or (3) is even more politically fringe than changing (1) is. Maybe that might change at some point though, who knows what the future holds.

And (4) will likely eventually cease to be true, but only in the long-run in which we are all already long-dead.


I don't mean that the two party system we have is due to first-past-the-post, it almost doesn't even really matter why we have it. But first-past-the-post is the mechanism which currently entrenches it and is the most likely to change. I think that (3) is a result of the system, not a cause.


It explains why you end up with two parties even if you start with more. The two largest will woo minority parties until they get a majority. And minority party members know they will be marginalized unless they are aligned with the majority (or hope to be in the majority some day.)

Changing that will require a radical reconsideration of democracy, like replacing FPtP with... something.


It doesn’t because the UK has FPtP yet doesn’t have a hard two party system.

Scotland, Wales and Northern Ireland have nationalist movements that want out of the UK-state independence movements exist in the contemporary US too, but they are very fringe

But even England has not just Labor and the Tories, but also the Lib Dems, Reform, the Greens, Restore

So England proves you can have multiple parties with real power, with FPtP, even in the absence of regional-nationalist movements


I dont see how the uk system's small parties are not marginalized. The larger parties still claim outright majorities with 35% of the votes or less (last time 172 seat majority with 33.2% of the votes) so they are irellevant.

If I am not mistaken all disruptions to fpp two party systems eventually settle back into them, maybe not the same parties but two nonetheless.


The smaller parties are all aligned with one of the two major parties. In a lot of ways they act more like caucuses than separate parties. Like Bernie Sanders being "independent".

That's overstating it, but it's why the largest group always can form a government. They go to the same aligned parties looking for a majority.


Can you elaborate what you mean?


In 2002, Hillary Clinton voted for the Iraq War. In 2008 Obama used that fact successfully to [help] win the Democratic nomination and went on to beat McCain.


> Okay then refresh the whole thing and not just a single row whenever TRR is triggered.

How would you refresh the whole DRAM? Refresh is simply reading the row and writing it back, it is sequential in nature.

> Or interleave activations with refreshes. Say, after every 5 activations, refresh the next row in the refresh cycle.

It makes zero sense. Refresh is disturbance in itself. You are entering a recursion here where the mere act of refreshing increases the counter values of victim rows making refresh even more frequent. At the end you have DRAM that you cannot read from or write to at all because it’s always refreshes itself.

> I'm not a DRAM expert

Yes


> At the end you have DRAM that you cannot read from or write to at all because it’s always refreshes itself.

Be so kind as to run the math on this for me? There must be something that I'm missing, because it looks like you're describing a system in which a refresh causes so much disturbance that another refresh is immediately required. Such a system seems incapable of reliably storing a byte and reading it back. The colloquial term for such a system is "unreliable garbage".


> you're describing a system in which a refresh causes so much disturbance that another refresh is immediately required.

Well, if you need to refresh a bunch of rows after any other read, you will spend more time refreshing things rather doing useful work.

That's not how infinite sequences work.

If each refresh causes 1/n more refreshes, then your total time spend on extras is is 1/(n-1) of your original number.

So even if you had an extreme 5:1 ratio, 100 accesses would cause 20 additional accesses which would cause 4 additional accesses which would cause 1 additional access. It would be fine.
