Rivian's pace of growth is far more measured (podcast very much worth the listen) and I think that until their smaller models arrive, their growth is going to be more constrained. The R3X is probably the first product that will make sense for an international market (since the R1T and R1S are both quite large) and that's not coming until 2027.

BMI is mostly useless metric when comparing genetically diverse cohorts. Weight gain is mostly in fat and that is proportional to fat cell count. There is a saying "nerve cells are born and die, but fat - lives forever". The truth to it is that at an adult age fat cell count is mostly constant and mostly genetic. As you get fatter you don't produce more fat cells, they just get fatter, pun intended.

There is huge genetic diversity between geographic regions / ethnic lineages in this regard. On one end you have northern european / african lineages, on the other end you have far east lineages, with other lineages somewhere in between, with northern european / african lineages having the largest fat cell counts, east asians the lowest. Furthermore, north european / african lineages tend to have fat distribution much more biased towards subcutaneous fat, whereas east asian lineages are biased towards abdominal fat, so many of the problems associated with high body fat (not insulin resistance) are seen at lower body fat percentages in east asian lineages.

On top of that, body fat percentage does not map to BMI. BMI may roughly linearly scale with body fat percentage around the "healthy" region, however there will be huge offset between genetic cohorts, including sex.

You should expect east asian BMIs to be lower across the board given similarly "unhealthy" diets.

Right, well even without AGI (no two people agree on whether it's coming within 5 years, 30, or 100), finely-tuned LLMs can disrupt the economy fast if the bottlenecks get taken care of. The big one is the robot-economy. This is popularly placed further off in timescales, but it does not require AGI at all. We already have humanoid robots on the market for the price of a small car, they're just dumb. Once we scale up solar and battery production, and then manufacturing, it's coming for menial labor jobs. They already have all the pieces, it's a foregone conclusion. What we don't know how to do is to create a real "intelligence", and here the evangelists will wax about the algorithms and the nature of intelligence, but at the end of the day it takes more than scaling up an LLM to constitute an AGI. The bet is that AI-assisted research will lead to breakthrough in a trivial amount of time.

With white-collar jobs the threat of AI feels more abstract and localized, and you still get talk about "creating new jobs", but when robots start coming off the assembly line people will demand UBI so fast it will make your head spin. Either that or they'll try to set fire to them or block them with unions, etc. Hard to say when because another effort like the CHIPS act could expedite things.

> Quite dystopian thinking how a full factory and beyond could be run completely in the dark, just robots running around doing their thing.

There is nothing dystopian about this image. Human being weren’t designed, evolved, nor destined to be a worker in a factory. Their absence in factories isn’t in and of itself a problem.

The dystopian part is how the wealthy and powerful will chose to use the fact that so much can be automated. I doubt they’ll be willing to use it to create Fully Automated Luxury Communism.
Fake reviews or just negative reviews? UK bans fake reviews
by aperi | 2025-04-08 14:02:09+00:00
2 days ago, the UK government banned fake reviews and hidden fees but the extent to which the former is enforceable is laughable to say the least.

A £2 Billion problem?

Apparently, £2B+ every year is wasted by consumers in the UK due to fake reviews and on the surface this seems like a problem needing a fix. So, I decided to dig deep.

After analysing more than 1000 products on Amazon (UK) alone across tech, fashion, accessories, and home improvement categories, only 17% reviews came out to be real — despite various strategies it all boiled down to the sentiment of reviews. About 12% reviews were duplicated which skews the average rating (for the thought that only purchasers can add a review) and about 33% reviews were 1-star or 5-star (just an observation and not too much of analysis here).

But all this data didn’t seem great enough due to sheer lack of volume (and patience), so I took a nap. After the hard earned nap, it occurred to me that this law would make it difficult to leave negative reviews. Most online platforms nowadays have a review system for user reviews which does a bad a job at not approving useful negative reviews.

It hit me — its almost like how YouTube removed the dislike count to support content creators and some PR statements.

So, what could this mean for us consumers? Difficulty in giving negative feedback or getting free returns without giving a feedback (some ebay sellers add this note with your package) or just a pseudo level playing field for all businesses to optimise for quality than reviews?

I don’t know that yet, but enforcing something that is nearly impossible to enforce is surely a fun way to utilise resources — this doesn’t mean it shouldn’t be a law but there must be publicly available and understandable measures to keep checks.

Thought I'd share some points and hear some :))

Why is it dystopian? This is how you keep cost of stuff low. Many people don’t realize that prices of cars have remained stable over last 20-30 years (beating inflation), because we outsourced and made a global economy work for us. Similarly the ‘cheap robot factory’ will output more and should cost less. Maybe we get a 20k car in next few years…

I will add that they are also a quite self reliant people; many of them live in areas where the government doesn’t provide much services at all (other than an occasional shakedown for a bribe). They are very good farmers. Their main opinion as I heard it expressed on foreign affairs is that they’d just like to be left alone and deal with less corruption.

One of the most amazing things was craftsmen who machine parts out of ebony wood or other tropical hardwoods - and use these to keep engines running. (I remain perplexed how they handle high heat, temperature changes, etc., but it works). I have never met a people more able to keep an ancient motorbike running.

Not everything gets counted in GDP… I am not sure the country would be improved if it somehow got replaced with a lifestyle of living like Europeans or Americans.

There are countless usecases for redirects.

A few examples of the top of my head:

when urls have changed,

when a resource/entity has been deleted,

when you wish to provide a unified entrypoint that sends users to another url so that you can easily change the redirection target in the future (i.e. redirecting a / to a /entities, so youre but blocking the / path if you want to add a homepage/landing page later)

I don't think I'd help with posts though. They do indeed usually send back a redirect - but the post is likely still in the history unless the website send it as AJAX/without a history entry (basically via JS fetch() instead of form action=)

The idea of taking an answer from any black box is profoundly unacceptable. Even if the black box didn't hallucinate. Why wouldn't I prefer to follow a link to a site so that I can evaluate its trustworthiness as a source?

Why would I want to have a conversation in a medium of ambiguity when I could quickly type in a few keywords instead? If we'd invented the former first, we'd build statues of whoever invented the latter.

Why would I want to use a search service that strips privacy by forcing me to be logged in and is following the Netflix model of giving away a service cheap now to get you to rely on it so much that you'll have no choice but to keep paying for it later when it's expensive and enshittified?

Just to clarify, GitMatcher is primarily designed for the sourcing stage of recruitment — helping recruiters and hiring managers discover devs based on actual contributions rather than résumés or LinkedIn profiles.

It’s not meant to be the only tool in the hiring process, but rather to help make the first step more data-driven.

I appreciate your thoughts — it helps make GitMatcher better.

It's more than that; it's also git's incredibly unfriendly way of naming things.

Take for example the "index" which is actually a useful thing with a bad name. Most tutorials start by explaining that the index is a staging area on which you craft your commit. Then why is it called index and not staging area? Incredibly bad name right there from the get go. If you ask what the word "index" means in computer science, people usually think of indices into an array, or something like a search index that enables faster searching. Git's index doesn't do any of that.

And git's model leaks so much implementation detail that many people mistake these for essential concepts; there are people who would tell you any version control system that doesn't have the "index" is not worth using because they don't allow one to craft beautiful commits. That's patently false as shown by jj and hg. This useful concept with a bad name becomes one amorphous thing that people cannot see past.

My public repos on GitHub are not a good way to judge me as a candidate. Not even close.

Frankly, I don't have much time to contribute to open source these days. I send a PR maybe once a year.

Almost everything on my profile is from my university days, and none of it is related to my career specialty (ML SRE).

And my employer asks me to fill out a form before I publish personal projects, so that they can be sure it is unrelated to my job (and thus that they do not have a patent or copyright claim over the code). This means most of my weekend projects simply aren't public, because I can't be bothered to do the paperwork.

LinkedIn, on the other hand, clearly shows where I've worked and what I've worked on. It's a much more accurate resume for me that GitHub.

I can’t decide if I’m skeptical of the entire concept or not. I guess I believe it will do something to the network to add this EMA of vectors in, so I’m surprised you didn’t get at least a change in animals after talking about cats. But, I’m not clear that reweighting logits at the end is super useful. I guess this is supposed to be in some way a realtime LoRA, but then what do you have except a super-undertrained LoRA, trained just off whatever conversations you’ve had?

I find the Win 11 start menu pretty bad. It's not as awful as a couple of the other attempts at revamping it, but worse than Win 10. Letting you get rid of the recommended stuff is a step in the right direction. Making it larger is a step in the wrong direction. If there were some way to configure it to be more compact and omit most of the frills, I'd be much happier with it.

Instead, I use stardock to replace it.

Yes, it's true, but digital services tax was only supposed to be temporary and the UK agreed to move away from it once a global tax system was negotiated at the OECD. https://www.gov.uk/government/news/uk-agrees-transition-towa...

I think those talks have ultimately stalled, so the right solution is getting back on track to a global tax system.

(Interestingly the deal struck in 2021 exchanged the promise of no US tariffs with the transition away from DST. It's no surprise this is a hot topic again with Trump's tariff regime.)

> I'm thinking, maybe controversially, centralized national payment service like this should be government-run based on my experience with Alipay which is a digital payment service in China.

After dealing with many private sector services, I think a lot of things should be government run.

For instance: weather apps. Private sector ones are just a vector to track and sell your location data, and they rely on government data anyway. It'd be much better the government roll out an API and an app that uses it, so you can avoid the private sector altogether.

> Unfortunately, that means that the tradeoff is that you're optimizing for user experience instead of developer experience

Not really, your backend has rich domain logic you can leverage to provide users with as much data as possible, while providing comparable levels of interactivity. Pushing as much logic (i.e., state) while you're developing results in a pale imitation of that domain logic on the front end, leading to a greatly diminished user experience.

> Or was it the gradual phasing out of mainframe-class hardware in favour of PC-compatible servers

Proprietary Unix is still around. Solaris, HP-UX and AIX still make money for their owners and there are lots of places running those on brand-new metal. You are right, however, that Linux displaced most of the proprietary Unixes, as well as Windows and whatever was left of the minicomputer business that wasn't first killed by the unixes. I'm not sure when exactly people started talking about "Enterprise Linux".

It is nice to see good news from time to time. I think the bigger question here is what role Chinese policy is playing in this story. Is their involvement strictly commercial? Have Chinese politicians decided on some sort of Marshall Plan-style approach to the Middle East?

The US has spent decades destabilising this region of the globe. I am hopeful that China and India will want peace and prosperity instead and we're hitting economic tipping points where they are going to start getting what they want whatever it is. The US isn't in a position to cause as much trouble now if the Chinese military thinks their western flank needs to start calming down.

It's hard to say, super subjective. It's just wrong more often and sometimes it goes off in tangents wrt. what I asked. Also I might ask a question and it starts coding an entire React project. Every once in a while it will literally max out its response tokens because it can't stop writing code.

Just feels less "stable" or "tight" overall.

Incredibly prescient. This quote from 2011 really sums it up:

> The original promise of the Californian Ideology, was that the computers would liberate us from all the old forms of political control, and we would become Randian heroes, in control of our own destiny. Instead, today, we feel the opposite—that we are helpless components in a global system—a system that is controlled by a rigid logic that we are powerless to challenge or to change.

I completely understand your situation. GitHub isn't the perfect fit for everyone, especially for those in specialized roles like ML SRE

GitMatcher is primarily aimed at the sourcing stage, where recruiters can find devs based on their actual code contributions. But I agree, it's not a one-size-fits-all solution — it's not meant to replace LinkedIn or fully capture your career.

> But surely you’d agree that “vat of chemicals” is not the only metric by which to evaluate a substance

So you're positing a spiritual or etherial nature for strawberries? Such that pure materialism is inadequate to address?

> , and that not all vats of chemicals are strawberries.

Yeah, this is elementary logic really. All A are B does not imply that all B are A.

> Everything is just a concoction of atoms.

yes, exactly. So what is the difference between an artificial and a natural arrangement of the atoms, if they are otherwise the same?

> The fact that they’re all just atoms doesn’t mean they share other properties like: safe to eat, tastes good to humans, etc.

Yes, which is why this wasn't my point.

> Yes, this is my whole point. The American Rescue Act and subsequent policies that were very much propping up salient jobs (certainly not wfh tech jobs that are, definitionally, resistant to lockdowns) fueled inflation that led to the end of zero interest rate period which led to large layoffs in tech.

Those are of little consequence compared to FRS interest rate policy. Also, those people need a place to work. Sorry.

> Flint falsifies your point, it is a democratic bastion. If you'd expect that to radicalize people, it should be deep deep read.

Democratic or Republican doesn't matter. When you have no more money because of major regional economic changes, you can't do the basic functions of government. There's also demographic differences.

> Out of bounds is a social norm over time. Donald Trump, their far and away champion, gives such egregious conduct I can't read this with a straight face.

That's what rage does.

> But we can go further back. Was 'just say no' not egregious enough for you? AIDS shaming? The vicious anger against gay people? I can take any snapshot of the past - conservatives will always be the cry bully at any of the years in time you want to pick.

You're confusing "conservative" with people in the part of the country that we're talking about.

Brazil was in constant economic chaos in the 80s and 90s, so the banking system invested a lot in automation and communications.

Off-topic, but the image captioned "Including workers in traditional dress handling solar infrastructure" looks AI generated. The workers on the extreme left and right are standing on solar panels, and the one in the centre is holding some metal bars that merge Escher-like with the panels behind him.

Even the caption sounds like part of an AI prompt to generate the image.

If you are like me, you have to stay ahead on (too) many fronts: - Clients: both companies AND stakeholders - Competitors - Tech advancements - Events - Regulations …

Last week, we launched SubstantAI (beta) to solve that problem.

As we hoped and expected, consultants and account managers got excited. But surprisingly many founders jumped on it too. So, I thought I’d share it here.

After a small week, SubstantAI is becoming more than “a cool personal newsletter” for our users. - Yes, they like that their AI screens everything they wish they did. - Yes they appreciate the curation/ that we’re solving information overload. - But what they love is that their AI suggests actions (not just FYIs).

We’re in beta and only offer briefs for now. But we’re of course putting this in an MCP server very soon.

Would love to hear your thoughts!

My Master's supervisor, at Wits university in Johannesburg, worked on the architecture of the 360 after graduating from the PhD program at Harvard. I remember him telling us how they went about deciding whether or not 32 bits would be a sufficient size for "most" floating point numbers. They were very systematic about it, scouring journals, talking with physicists and mathematicians and so on.

I was thinking about this and realized that if we want an AI boom to lead to UBI, AI needs to start replacing the cushy white collar jobs first.

If you start by replacing menial labor, there will be more unemployment but you’re not going to build the political will to do anything because those jobs were seen as “less than” and the political class will talk about how good and efficient it is that these jobs are gone.

You need to start by automating away “good jobs” that directly affect middle/upper class people. Jobs where people have extensive training and/or a “calling” to the field. Once lawyers, software engineers, doctors, executives, etc get smacked with widespread unemployment, the political class will take UBI much more seriously.
