esperent··on Reasons to Dislike AI Coding
> as cnc grew, machinists shrunk in headcount and wage.

Headcount, yes, wages, no.

However, you're assuming that cnc operators can't be artisans. Why?

If we allow anyone with a craft to be considered an artisans if they have a high enough skill level - and we should - I'd counter that the overall number of artisans has likely increased even if less of them now have the title of machinist.

> I wonder how much AI companies lost on this?

Probably zero, or even a profit. The idea that these companies are making a loss on subscriptions is an unsubstantiated HN fallacy.

On the contrary, they're probably making a small profit on subscriptions, or at least break even, and absolute bank on API pricing. Anthropic recently reported an 80% gross profit margin, for example.

> I suspect they are all a bunch of shysters opportunistically abusing us.

At this point we conclusively know that.

What frustrates me is the constant unshakeable belief here that subscriptions must be running at a loss, based on zero evidence.

Anthropic have said they have 85% margin, which presumably means their normal API pricing. 85% margin is insane. No business deserves that. We can easily assume the subscription is running at a more sane margin like 5-15%.

I did the same and my billing also starts tomorrow so... I guess we'll find out!

Also how tokenization works. There was a post the other day saying 150k OpenAI tokens is equivalent to 250k Anthropic tokens.

Can't find the link now it was a the pi harness author saying you could load the entire harness into context with those budgets IIRC.

I'm absolutely hitting the limits with 6.1. I'd say maybe hitting them a bit slower than before, but only because the model is dog slow, not because it's more efficient.

My chatgpt pro account gave me 62k of their "credits" which they try to sell you at extortionate rates when your subscription runs out. I spent two days hammering it and used about 4k of those.

This is clear manipulation to prevent me from complaining about lower limits until it's out of the news cycle, but I don't care. As soon as those are gone, if my $200 account doesn't give me the value it used to, I'm out.

The random resets are also clear manipulation in this regard as well. Rather than just give me a fixed weekly limit which I could then get a sense of and know if it's getting reduced, they throw out a ~0-3 resets a week at random, unexpected intervals so that I'll never know.

esperent··on Opus 5.5 agents discover two room-temperature magnetic semiconductor candidates
The title has been editorialized.

Actual title:

Two Room-Temperature Antiferromagnetic Semiconductor Candidates

There's nothing unusual about finding room temperature semiconductors. I assume whoever posted it misread this as room temperature superconductors, but it has nothing to do with that.

What's interesting here is the antiferromagnetic part of the title, which was removed. I think this makes it relevant for e.g. RAM, but not superconducting. Someone can correct me if I'm wrong.

No, the implication is that something "tastes off" so you need to add a pinch (+) of salt to make it palatable. The more off it tastes, the more salt you need.

(+) Or a "grain" if you're from the US since American English sayings seem to all date from the middle ages, while the rest of the English speaking world tends to update ours over time. No shade meant, I've just always found that interesting.

esperent··on The technology to eradicate mosquito-borne disease exists
I did read the article, actually. It says they did a randomized trial of wolbachia infected mosquities, presumably on a small area, while the person I was replying to was implying that all mosquitos in Singapore have been eradicated. So presumably they're also using other methods like DDT spraying.
esperent··on Norway Eyes Partial Ban of Smart Glasses
> This seems similar to how much of SE Asia requires a “click” sound from camera apps

I live in "SE Asia" - specifically Vietnam - and I've never heard of such a law. I just looked it up and the two countries that come up are Korea and Japan, neither of which are in SE Asia.

esperent··on The technology to eradicate mosquito-borne disease exists
Do they achieve it by regularly spraying poison on the air like they do in Malaysia? Feels like a pyrrhic victory to me. I know they were trialing genetic modification but I don't know how successful that was and I'm certain it's not the only thing they're doing.

Maybe you're right. It definitely wasn't possible a couple of years ago but I'll look into it again, thanks.

Years ago I had a kobo and put kohreader on it. But I left it on a bus and got a kindle Paperwhite as a replacement. I definitely regret that and second this comment: kohreader is such a superior experience. I'll never again get an ereader that can't run it.
esperent··on Why don't more developers “use the platform”?
Here's equivalent svelve code. I can't format it correctly because I'm on mobile but even without proper indentation it's easy to read.

<script> let count = $state(0); let dialog; </script>

<button onclick={() => { count++; dialog.showModal(); }}> :) </button>

<dialog bind:this={dialog}> <p>Hello, I was clicked {count} times</p> <form method="dialog"><button>Close</button></form> </dialog>

> web components are browser native

I would say very few people are using bare web component. They'll be using a library like Lit at the very least, so your argument is moot.

esperent··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
> MIT does not wave the right to attribution

Waive. And no, it doesn't but it doesn't require attribution either. So you're falling back on copyright law which is unlikely to protect you here - there's a reason people include licenses, after all.

esperent··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
Morally, I completely agree, but legally that's not something you can prevent with a weak license like MIT.

It might be possible to pursue this as illegal under general copyright law but it would be difficult.

If you don't want something like this to happen to your work, use a stronger license.

It's not stolen. It's MIT licensed and the attribution is still there.

esperent··on 1 in 8 cancer cases worldwide are caused by infections, study finds
There's downsides to heavy or frequent drinking, sure. But since the cancer risk is minimal, what's the downside of a glass of wine or beer a couple of times a week?

I'm less convinced of the negatives of this than I used to be. Humans are quite well adapted to alcohol.

If it's something you enjoy, I'd say go for it, in moderation. It's probably less unhealthy than e.g. living in a city, eating processed meat, or working an office job.

esperent··on Jev Can't Be Calibrated
> The true probability of face 1 is 1/6, but Jev always chose face 1 and the probability it returned was about 83%

I think this is a misunderstanding of what that 83% probability means. You think you're asking Jev to assign a probability to a dice roll, and if so then obviously it should pick each answer 1/6 of the time.

However, what Jev is doing is assigning a probability to the answer it should choose. And it's choosing 1 with 83% probability, as the correct answer to give, when there's no additional knowledge available.

1 is a perfectly valid answer here. In the absence of other data there's no more (nor less) valid answer than that. and I assume that just like LLMs, the token prediction must assign higher probability to one outcome.

If you keep feeding the previous answers back in (if you can do that with Jev) I assume it would start giving other numbers because it's no longer operating from zero info. Maybe that would even reach ~1/6 after enough rounds, although maybe not.

esperent··on Apple M6 Pro Achieves the Highest Single-Core CPU Score in Geekbench 7
There's also the Snapdragon X2 Elite Extreme, 3,438 points in single-core and 27,519 points in multi-core, which I think was the record when it was released a year ago.

I guess they'll release an X3 in six months. So it's interesting to see the race is now between Apple and Qualcomm, both on Arm, with Intel and AMD getting left behind, at least on this benchmark.
