> If I ate like her I'd die of a heart attack before I turned 40. And I'd be pretty obese, too.

No you wouldn’t. Obesity rates back then were near zero. For the general population, not just for farm laborers. Heart disease killed far fewer people per capita per year. If you remove the infectious diseases that we have practically cured, mortality per capita per year in 1900 and 2020 is pretty similar.

Mind you, those infectious diseases were 90% eliminated by sanitation and understanding and 10% modern medicine; tuberculosis deaths were down by 90% from the 1860s to 1947, which is when streptomycin, the first antibiotic effective against TB, was used.

For some time I ate similar diets to the one you describe - a poor farmer’s diet high in potatoes and bread, with some vegetables, meats and dairy - and I know people who eat that diet today. None of them are fat. It’s because potatoes and bread aren’t very calorie-dense. It is difficult to eat a caloric surplus every day when the majority of the food in front of you is greyish brown, vaguely mushy and of a sufficiently insufficient density that you must take your time to eat it. Modern processed foods, even the fairly simple ones, take the labor out of eating and make the regular things around us infinitely snackable. Modern foods have just the right amount of sweetness and salt and crunch with the right color and appealing packaging and advertising and so on. A standard potato in a standard kitchen will never have that. There’s a reason why obesity rates precisely track consumption of processed foods.

Gmail has no desktop app, though it has mobile apps.

The web or PWA Gmail has more features and settings than any third-party desktop app would offer when using IMAP or POP. Gmail is a custom-designed first-party app. If you read mail from Google through Outlook or Thunderbird, it will have lowest-common-denominator features through the lens of a different vendor's structure.

Now you may consider it a superior advantage if the Gemini AI isn't available, but probably won't be able to create custom filters without the PWA.

I don't think AI is a sham, but I would like to see more effort to quantify AI's improvements to productivity and practical applications - rather than countless charts detailing the increasing watts and flops and GPUs and dollars being dedicated to AI. I have zero doubt that companies are spending a lot of resources on AI. It's difficult to exist in society and not recognize that.

There were a few practical use cases mentioned here, but the only quantified impact to worker productivity from LLMs that I noticed was a single study of call center agents from 2023 that showed a 14% increase in cases handled per hour.

> I cannot help but feel that all ai stuff is entirely incapable of replicating the real thing

But that's what they were saying about a simple paragraph of coherent writing five years ago. And what they were saying about structured output three years ago. And now I can ask for a coherent breakdown of the functionality that might be required for a ticket tracking system, with a list of use cases and screens to support them, and user personas, and expect that the result will be a little generic, but coherent. I can give Claude a picture of a UI and ask for suggestions for improvement, and half the ideas will be interesting.

Farmers do an intense amount of work. The only other profession that works out as much in the modern economy are professional athletes and maybe elite soldiers. Also, farmers get tons of sun, which has beneficial effects on health as well as the deleterious effects people endlessly repeat: although it does raise the risk of skin cancer, it decreases the risk of other cancers so much that total cancer risk is lowered.

No one is asking you to spell out the edge cases, but when you claim that a halting oracle can be used as a general-purpose theorem prover and I point out the edge cases where that won't work, it's pretty egregious to then say that I'm mixing things up, I am misusing standard terminology, etc...

If you claimed every prime number is odd, and I point out that 2 is an even prime number, you don't get to turn around, pull out your credentials, claim I'm mixing things up and bickering around because I am pointing out an exception to your generalization.

The fact is a halting oracle cannot be used as a general-purpose theorem prover. At best it can be used as a way to classify theorems in specific first order theories with recursively enumerable axioms and I even admitted that much in my original response to you.

That some first order theories do not have recursively enumerable axioms and for these theories even an oracle for the halting problem is insufficient to either prove, refute, or classify as independent particular propositions is actually a fascinating topic in and of itself which could have led to a much more engaging conversation than the one you decided to go with by talking about your failed academic career and claiming I'm misinformed, but alas that ship has sailed and at this point and with that I don't think there is much further to discuss here.

I think actually 4o image generation in ChatGPT is still a tool call with a prompt to an “image_gen” tool, I don’t think the generator receives the full context of the conversation. If you do a ChatGPT data export and inspect the record of a conversation using 4o image gen, you’ll see it’s a tool call with a distinct prompt, much like it was with dalle. And if you pass an image in as context, it’ll pass that to the tool as well.

I imagine this is for anti-jailbreak moderation reasons, which is understandable

"The country is Europe’s largest oil and gas producer, which helps support Norwegians’ aspiration to live green. Norway has invested its fossil fuel profits into what has become the world’s largest sovereign wealth fund, a nest egg worth $1.7 trillion. Returns from that fund help cover government expenses, which in turn makes it easier to accommodate climate-friendly tax exemptions."

> This is false because the interchange fees, and in fact all of the fees, have to pay for the entire company’s operations, not just for your points program.

Sure. But the default and reasonable presumption is that at that scale, companies do things because they're profitable; in this case, they implement rewards programs because they make more money by doing so. In particular, the default and reasonable presumption is that companies don't spend more money acquiring a class of customers than they expect to make from those customers. The claim by the Atlantic article is that credit card companies lose money on the rewards programs for rich people. There's no evidence of that, and some evidence to the contrary.

> Without more detailed data it’s not possible to rule out the possibility that points programs are a subsidy for the rich.

That's not where the burden of proof lies. Without more detailed data it's not possible to demonstrate that rewards programs are a subsidy. The conclusion is not presumptively valid.

I'm not suggesting, either, that the argument from the linked Twitter thread is ironclad, just that it's compelling evidence against.

> The second assumption he makes is that volume is the same across the board. It’s not, there’s way more customers on the lower end, and the company charges them even more fees. So sure, rich customers individually pay more interchange fees, but the company could still be making most of its money from poor customers.

"more customers on the lower end" is in fact refuted by the data; see figure 2 (F) in the linked paper.

"making most of its money from poor customers" might be true, but note that figure 2 (E) is scaled by "percentage of average daily balance", and if you were to view it in absolute terms, it seems less likely to be true. Even if it were true, though, it's not evidence of a subsidy of rich customers by poor customers. The credit card companies very obviously think that rich customers are profitable to acquire and keep, or they wouldn't pursue them so heavily. The evidence from the thread supports that claim.

The argument being made in the thread is, precisely, if the rewards program pays for itself an individual customer, that customer is not being subsidized in any way.

If you want to claim that the rewards programs offered to richer customers aren't in fact profitable for the credit card companies, that seems like an even more extraordinary claim, and not one that seems to have supporting evidence.

Alternatively, if you want to define "subsidy" so broadly that any business making more money from one group of customers than another is having one group of customers subsidize the other, even if they are making money from both, then I'd question your definitions and use of evocative terminology. They're spending money to get a group of customers, and if they're spending more to get those customers than they make from those customers, they wouldn't spend it in the first place; if they're spending less to get those customers than they make from those customers, then those customers are not being subsidized.

There's definitely an element of what we saw in the '90s -- software didn't always make people faster, it made the quality of their output better (wysiwyg page layout, better database tools/validation, spell check in email, etc. etc.).

But we're going to get to a point where "the quality goes up" means the quality exceeds what I can do in a reasonable time frame, and then what I can do in any time frame...

The solution not existing in PyTorch does not mean the solution doesn’t exist elsewhere on the internet. Remember - PyTorch is largely maintained by employees of companies that have their own priorities for the SW and those priorities may not include hyper optimizing fp32 kernels.

That being said, it is cool if AI is enabling lower cost adoption of better more optimized kernels with less effort.

Get your point but could you mention a specific LLM? Cuz the ones I’ve tried honestly aren’t great at truly emulating style, even with context.

Also, this one claims to be different. It’s not just prompt-based mimicry, with the need to say "write like me". It stays in your voice for everything, even something as small as a “how are you” message. You don't need to ask it to write in this style and that style every time.

Considering New Hampshire’s lack of sales tax, I’m patiently waiting for Micro Center to establish a new presence in Nashua or Salem. The Cambridge location, while personally cherished, isn’t that accessible by car because of Boston’s stress-induced car traffic congestion. Even on foot, getting to the store is still a bit of a journey. Also, let’s not forget Massachusetts’ 6.25% sales tax.

In New Hampshire, I am positive Micro Center would attract customers from all over New England and make an absolute killing from sales, potentially overshadowing their Cambridge profits. I would never shop online or in Cambridge for hardware again. But, I’m sure they wish not to jeopardize the Cambridge store or their MIT and Boston tech hobbyist clientele. Otherwise, I am surprised they have not yet acted upon this idea.

But, a man can dream!

Things I love:

1. Start and stop button. I love this explicit control over who is talking when.

2. Ability to upload files while the voice chat is going. Great idea. Often times I use gpt voice chat for studying, and it's annoying when I need to add another PDF to the context, since I need to stop the chat, upload, and then restart the voice session.

3. Real-time text display during voice chat. I asked you to take the derivative of a function I described, and it outlined its steps, but it wasn't just the transcription of what it was saying.

Things I hate:

1. The transcription is terrible. It took me 10 tries during the conversation to describe f(x) = x^2. Looking back on the transcriptions, it's literally nonsense.

2. There was a buggy moment when the voice conversation started but it was still demoing all the voice options simultaneously. Need some polishing.

That only means you need a couple of instructions to do each one [1]. The five output registers are each dependent on (at most) a pair of the four input registers, but not on each other.

[1] a left shift, a right shift, and an OR. Or just one 2->1 funnel shift instruction if your ISA has that e.g. arm64. And then ANDing with a 51 bit mask.

> The issue with AVX512 is not (just) that you need a very wide vector unit, but mostly that you need an incredibly large register file

Not necessarily, you need to behave as if you had that many registers, but IMO it would be way better if the E cores had supported avx512, but half of the registers actually didn't exist and just were in the L2 cache.

This may be my single biggest pet peeve. I think of this problem more broadly every time I see some new movie is the highest grossing movie of all time. No shit, Sherlock. More people, more screens, more movie theaters, inflation... the record is always going to be broken.

I hate this so much I actually ran the numbers and saw that per capita box office revenues have remained generally stable since the 1980s.

GCS's metadata layer was originally implemented with Megastore (the precursor to Spanner). That was seamlessly migrated to Spanner (in roughly small-to-large "region" order), as Spanner's scaling ability improved over the years. GCS was responsible for finding (and helping to knock out) quite a few scaling plateaus in Spanner.

Yeah, I totally get that! W++ isn’t meant to copy Python’s syntax exactly — instead, the inspiration from Python is in its simplicity and low barrier to entry.

I drew from multiple languages — Python, JavaScript, even a little C-style flavor — to make something that’s readable, expressive, and beginner-friendly, especially for quick scripting in .NET.

Appreciate the suggestion! I’ll make sure the SYNTAX.md is linked more clearly from the README.

Presumably the semaphore would be used to limit the number of concurrent virtual threads.

Incoming tasks can be rejected proactively if a system would overflow its limit on concurrent tasks. This approach uses a semaphore’s non-waiting acquire and release operations. See the “bulkhead pattern.”

Alternatively, if a system has a fixed number of threads ingesting tasks, these would respond to backpressure by waiting for available permits before creating more virtual threads.

I thought article would be about significant battery capacity loss in freezing weather - ie ( from Google ) ...Another study by Recurrent showed the loss can be up to 30% in cold weather between -7 and -1 degrees. In both studies car model and battery size mattered. So while you don't lose all your range, colder temperatures do affect your EV range......

but no mention of range loss in freezing weather ....

A bit of both. The ones who said it and meant it were always a minority, the rest who said it were saying it because it let them fit in. Once power shifted, they switched their message because their position has always been about obtaining and retaining power, not about taking a stance.

The power in a political party (in the US) is never really held by a principled faction of the party, it's bolstered by the unprincipled majority that see public support leaning one way or the other and choose a (somewhat) principled faction to throw themselves behind.

>logistics of moving and living in another country are always harder than expected, both culturally and bureaucratically.

You know what's hard? Moving from a poor "shithole" to a wealthy country, with expensive accommodation, where a month of rent is something you'd save up months for.

Knowing and displaying (faking really) 'correct' cultural status signifiers to secure a good job. And all the associated stress, etc.

Moving the other direction to a low-cost-of-living or poor shithole country is extremely easy in comparison with a fat stack of resources.

You literally don't have to worry about anything in the least.

The problem seems to be two-fold.

Firstly, the capex is currently too high for all but the few.

This is a rather obvious statement, sure. But the impact is a lot of companies "have tried language models and they didn't work", and the capex is laughable.

Secondly, there's a corporate paralysis over AI.

I received a panicky policy statement written in legalaise forbidding employees from using LLMs in any form. Written both out of a panic regarding intellectual property leaking but also a panic about how to manage and control staff moving forward.

I think a lot of corporates still clutch at this view that AI will push the workforce costs down and are secretly wasting a lot money failing at this.

The waste is extraordinary, but it's other peoples money (it's actually the shareholders money) and it's seen as being all for a good cause and not something to discuss after it's gone. I can never get it discussed.

Meanwhile, at a grass roots level, I see AI is being embraced and is improving productivity, every second IT worker is using it, it's just that because of this corporate panicking and mismanagement, it's value is not yet measured.

Worse yet, AI has been consuming Scott Adams quotes as part of its training...

"The reality is that women are treated differently by society for exactly the same reason that children and the mentally handicapped are treated differently. It’s just easier this way for everyone. You don’t argue with a four-year old about why he shouldn’t eat candy for dinner. You don’t punch a mentally handicapped guy even if he punches you first. And you don’t argue when a women tells you she’s only making 80 cents to your dollar. It’s the path of least resistance. You save your energy for more important battles." -Scott Adams

"Women define themselves by their relationships and men define themselves by whom they are helping. Women believe value is created by sacrifice. If you are willing to give up your favorite activities to be with her, she will trust you. If being with her is too easy for you, she will not trust you." -Scott Adams

"Nearly half of all Blacks are not OK with White people. That’s a hate group." -Scott Adams

"Based on the current way things are going, the best advice I would give to White people is to get the hell away from Black people. Just get the fuck away. Wherever you have to go, just get away. Because there’s no fixing this. This can’t be fixed." -Scott Adams

"I’m going to back off from being helpful to Black Americas because it doesn’t seem like it pays off. ... The only outcome is that I get called a racist." -Scott Adams

I used to love visiting the Microcenter near our family home back in the early 90s. In those halcyon days, they had a exceptionally LIBERAL return policy - 30 days even on opened software. (the L.L. Bean of electronics).

As a child whose modest income was derived solely from weekly lawn mowing, needless to say I coincidentally became quite accomplished at beating PC games within a month's time.

In defense of my somewhat dubious behavior, I did go back as an older teenager with far more disposable income and purchase a ton of big-box PC games from them. Most of which I still have including one of my all-time favorite RPGs, Betrayal at Krondor.

We built the pilot to show a standard lightning invoice with a QR code and NFC. Any wallet capable of paying that invoice could pay.

Whatever wallet you use did need to have liquidity on the network that can reach our routing node, c=, but we worked hard to make sure we had plenty of liquidity to all major wallets. I definitely recommended cashapp without shame at the conference, but I did a lot of testing with other wallets too. I never had much trouble, even with non-custodial lightning wallets.
