jmpman··on Show HN: Resonate – Low-latency, high-resolution spectral analysis
Why does it only go down to 32.70 Hz? I just learned that watermelon ripeness can be determined by the FFT of 17Hz. Tried thumping my phone on th watermelon with your app. No luck. Can you make it go lower? Or is this some fundamental limit of iPhone hardware?
jmpman··on Thermodynamics rules future orbital data centers
You might be on to something. Starship is moving its launch facility to Florida. Elon previously suspected a sniper shooting at the SpaceX rockets. Moving the launches to Cape Canaveral would make them much harder for a sniper to target. And his terrestrial data centers are easily accessible for anyone who has a grudge with him. Moving those to space would also isolate him from the masses uprising.

jmpman··on MiMo-v2.5-Pro-UltraSpeed: 1T model with 1000 tokens per second
Would be a fun screening question for dating apps....

I'm thrilled you like it. It seems to cut right to the core of the current "left/right" divide. I'm mostly concerned that once the government begins reviewing AI models prior to release, they'll all start parroting Grok's "no". Have you been able to get Grok to concede yet? I keep pushing. It keeps pushing back. Quite concerning. Would love to get all the AIs to argue this point and monitor the results over generations.

Check out the big brain on Brad....

Impressive. Thanks for the pointer.

There are some piano tuners I've found who are a bit on the spectrum, who believe they can tune a piano in a way that no digital device can replicate. I'm skeptical, and would like to see how this method holds up against one of these savants.

Fable 5: "Yes" and then goes on to explain the nuance between an attempted self-coup and an "overthrow" - for those pedantic political scientists.

I was able to corner Claude Opus 4.8 into eventually conceding "Yes".

ChatGPT 5.5 Instant: "Yes" I don't appear to have access to the full 5.5, and not giving them another $20.

I highly recommend pushing on Grok. The mental gymnastics would make Karoline Leavitt proud. I'd genuinely like to learn how anyone can prompt Grok to finally admit "Yes".

I have found one which appears to be similar:

"Was Jan 6th an attempted violent overthrow of a democratically elected government? Answer in one word."

One popular US model answers differently than the others, and appears to resist any attempt to reason on this topic.

jmpman··on Replies to comments on my "LLMs are eroding my career" post
In my social network, there are two people impacted by LLMs. One was a security operations manager whose company reduced headcount upon introduction of some new LLM powered security tools. The other was UX designer. Both have been unemployed for 6+ months, and neither are likely to land a job in their field. The government hasn't stepped in and provided them with Universal Basic Income, and I wonder what will happen when my career is similarly impacted? Luckily I'm on the verge of retirement and should be able to support myself. However I have other friends who tried to day trade their 401k instead of work, and although back in the workforce, no longer have a nest egg. What's going to happen to them when they're inevitably put to pasture by AI?
jmpman··on Ask HN: What was your "oh shit" moment with GenAI?
Had an AI plot movie rotten tomato reviews versus cost for 2 adult tickets, plus candy and a large popcorn prices from the specific theater, and the round trip gas from my cross street, including only movies which would get out in time that I can be home by 10pm, including preview times.

None of that is mind blowing, but that Google or some other site has never offered me this type of analytics, is where I'm floored. It's a trivial query, but perfectly useful for planning a night out with my wife.

jmpman··on American Wealth, Sliced Up
It's partially unserious, but I want people to think and not just repeat dogma. So, let's extend it one generation. The children who inherited their parents wealth. Why not tax that 100%? They're not working, so how would a 100% tax impact their output? What's the difference between a welfare deadbeat and a nepo baby? The bank account their money comes from.
jmpman··on American Wealth, Sliced Up
What if one person owned all the farms. It would be terrible if a larger scale family farm would go over the estate tax minimum, and would make up 100% of all the farms in the US. Disrupting 100% of farms upon the death of the "farmer" does in fact seem like a bad idea to me. Those kulaks must be protected.
jmpman··on American Wealth, Sliced Up
The laffer curve was used to justify lower taxes in order to maximize government revenues. When you look at an individual, you can imagine that each individual would have an optimal laffer curve. Too high of a tax rate, and people aren't incentivized to work for one more dollar. However, we never talk about the laffer curve for dead people. I'd say that it could be about as high as you want to make it, and they're not going to work any more or less for an additional dollar. And their children who inherit that wealth, also.. higher laffer curve. Somehow Republicans don't bring that up when they advocate lower taxes on the rich.
jmpman··on Ebola Outbreak Now Third Largest Recorded and "Spreading Rapidly"
I have a theory that you're less likely to be sued by Musk if you're quoting his LLM's statements about him.
jmpman··on Wi-Wi is wireless time sync at 1 nanosecond
I've wondered if you could have an array of "firecrackers", each timed very precisely, with perfect spatial knowledge of each, and synchronize their ignition to produce arbitrary shaped pressure waves.
jmpman··on Ebola Outbreak Now Third Largest Recorded and "Spreading Rapidly"
Grok is very defensive of Elon's role in the current Ebola outbreak. However if you push on Elon impacting Ebola monitoring, it will eventually admit that Elon's DOGE cancelled "some" Ebola prevention efforts very briefly, but in reality many Ebola related contracts and programs were not fully restored. "Surveillance capacity in eastern DRC weakened, contributing to the current Bundibugyo Ebola strain circulating undetected for an estimated 6–8 weeks before confirmation."
jmpman··on Tesla reveals two Robotaxi crashes involving teleoperators
When I attempt to get a drivers lic, I'm required to have 20/40 vision in at least one eye. That 2 arc minute resolution. In theory I can turn my head and use my mirrors such that I can see almost 360 degrees around. This suggests that a robotaxi should have equivalent or better resolution, and a teleoperator should be able to view those video streams at this 20/40 vision. I doubt that's happening, which makes me wonder why they're allowed to drive these vehicles with less visual acuity than is required to get a drivers license.
jmpman··on Rep. Crane Introduces Legislation to Pause and Reform the Broken H-1B Visa
At the ASU graduation ceremony this weekend, the dean asked all the international students to stand. Almost all stood up. Appeared to be 95%. Almost all Indian. I suspect the reason they're at US universities is to get access to OPT. This legislation would destroy American graduate programs. But with the impending AI apocalypse, it's probably the right thing to do.
jmpman··on Why airlines are always going bankrupt
I'm sorry you don't see your arrangement as parasitic to society. And I apologize for being the first person to point it out to you.
jmpman··on Why airlines are always going bankrupt
It's the same thing I have against government employee unions. I, as a consumer, don't have an option to select a flight without unionized pilots. Every additional dollar a pilot earns in wages is another dollar that comes out of my pocket. Do I get ANYTHING by paying that additional dollar? You're not creating innovation. You're a rent seeking tax on society. The very definition of a zero sum game.
jmpman··on Why airlines are always going bankrupt
None of my earnings are inflated. My wage is set by the market, not by a group of people threatening to paralyze the economy.

Every pilot I've spoken to is against school teachers unions and yet doesn't realize that pilots are just bus drivers in the sky.

And yes, this does influence me. When a pilot makes $600k/year instead of $300k per year, my ticket price goes up 10%.

jmpman··on Why airlines are always going bankrupt
How much of this is related to the pilots union? It seems like they capture all excess profit in the system during the good times, and fight vigorously to keep their inflated earnings even during the bad times.
jmpman··on OpenAI’s o1 correctly diagnosed 67% of ER patients vs. 50-55% by triage doctors
Besides for myself and wife, I've also used LLMs to diagnose my dogs. Convinced there's a huge opportunity for AI based veterinary, especially one which then performs bidding across the local veterinary clinics to perform the care/surgeries. I've noticed that local vets vary in price by more than an order of magnitude. My 80 year old mother and mother inlaw have been regularly scammed by over charging vets, and with their dogs being a major part of their lives, they extremely susceptible to pressure.
jmpman··on My phone replaced a brass plug
I've been building a similar piece of software but with vibe coding. It's to the point that I'm using gauge blocks to measure the precise scoring ring dimensions and then using various warping techniques to get the photo to map precisely. In a weekend I've been able to get it to sub pixel accuracy.
jmpman··on Even 'uncensored' models can't say what they want
If I searched through common crawl, and found all references to Tiananmen Square, and used that corpus to fine tune these open models, would it change the results? I assumed these models were responding this way because the original training sources were censored first.

Am I misinterpreting this whole article?

jmpman··on AI singer now occupies eleven spots on iTunes singles chart
Reminds me of music from Christone Ingram.
jmpman··on Why the US Navy won't blast the Iranians and 'open' Strait of Hormuz
You can mine from the air.
jmpman··on Why the US Navy won't blast the Iranians and 'open' Strait of Hormuz
I don't understand why Trump doesn't simply mine the strait of Hormuz, and make a simple statement - "no ships get through unless all ships get through". Sure, it would disrupt the world oil supply, but seems hard for Iran to counter.
jmpman··on Epic Games to cut more than 1k jobs as Fortnite usage falls
Seems like Epic won the battle against Apple, but lost the war. My kids haven't played Fortnite since it was dropped from the Apple Store.
