How can research claim the genetic component of IQ is so high when there are so many environmental variables that have to be accounted for in order for the genetic component to even be able to manifest?

For example, if two identical twins are separated at birth. If one is raised in an educationally rich and nurturing environment and the other is raised in a horribly abusive and neglectful environment, then I am not sure the two would probably score the similarly on any given IQ test despite their genetic commonalities. Meanwhile, I imagine things like eye color, hair color, etc. which have a strong genetic component would remain consistent between the two.

It’s called forward collision avoidance assist (a safety feature).

There’s another safety feature for reversing which stops your car in its place when there’s a car passing behind you, for example as you’re exiting a driveway.

Coupled with pre-collision throttle management, it provides exactly the experience I am describing—the car comes to a stop.

Granted, I don’t speed, so maybe that’s why it’s easier for these features to manage the car in these cases.

> You seem to be speaking about your own link, not the linked article on Hacker News.

Correct. The hacker-news linked article talks about drugs that made mice live longer, my article talks about drugs that made humans live longer with some supporting evidence from mice studies.

> Be especially careful with TRT advice on the internet or from local clinics that push TRT treatments.

Correct. If you read my article, it repeatedly talks about working with a Dr on this. Ideally an endocrinologist (in USA), or potentially a urologist.

Healthy doses of TRT, where studies found benefits are with hypogonadal men whose low T is verified via two separate tests (<200 or <250 total T). The dosages used (~100 mg / week or less) are nowhere near gym bro doses (~200, 300, 400 mg/week etc).

An endo will ask you to make lifestyle changes first, and resort to supplemental testosterone as a last resort.

> it’s on the short list of medicines that can make you permanently dependent by causing testicular atrophy.

I believe you're factually wrong on this. I know a lot of people personally who stopped TRT successfully, some after being a decade on it.

> It’s not appropriate to mix into a list of supplements to take

This is a non-sensical idea, because supplements are much like drugs except they don't go through the FDA approval proceess. They're simply unregulated drugs with potentially significant sides. You shouldn't take a light view of them.

Actually, if I were to choose between a drug and a supplement for the same problem (such as living longer), I think people should prioritize drugs first as they go through rigorous clinical trials, their side effect profile is well known, there's post-approval drug monitoring.

Cool idea. I grew up with the most basic Snap Circuits kit[1] and a solderless breadboard kit from RadioShack[2] - other toys you might look to for inspiration.

I think I was about 12 when I got these, and I remember that the learning curve between them was pretty steep - I was building all sorts of custom circuits with Snap, but had maxed out the capabilities of such basic parts pretty quickly. I never did figure out how to make anything other than the step-by-step projects with the breadboard kit. Although the ICs on Snap are kind of laughable, I could at least figure out what they did (also I seem to remember every one of them just played a sound), but the Radio shack kit never really explained why anything worked the way it did or what the applications were outside of its recipes, so eventually it just went on the shelf and was forgotten. That would be one trap to avoid from my experience.

4chan's response (through lawyers): https://x.com/prestonjbyrne/status/1956391746029428914

Full text:

"BYRNE & STORM, P.C.

ATTORNEYS-AT-LAW

Re: Statement Regarding Ofcom's Reported Provisional Notice - 4chan Community Support LLC

Byrne & Storm, P.C. ( @ByrneStorm ) and Coleman Law, P.C. ( @RonColeman ) represent 4chan Community Support LLC ("4chan").

According to press reports, the U.K. Office of Communications ("Ofcom") has issued a provisional notice under the Online Safety Act alleging a contravention by 4chan and indicating an intention to impose a penalty of £20,000, plus daily penalties thereafter.

4chan is a United States company, incorporated in Delaware, with no establishment, assets, or operations in the United Kingdom. Any attempt to impose or enforce a penalty against 4chan will be resisted in U.S. federal court.

American businesses do not surrender their First Amendment rights because a foreign bureaucrat sends them an e-mail. Under settled principles of U.S. law, American courts will not enforce foreign penal fines or censorship codes.

If necessary, we will seek appropriate relief in U.S. federal court to confirm these principles.

United States federal authorities have been briefed on this matter.

The Prime Minister, Sir Keir Starmer, was reportedly warned by the White House to cease targeting Americans with U.K. censorship codes (according to reporting in the Telegraph on July 30th).

Despite these warnings, Ofcom continues its illegal campaign of harassment against American technology firms. A political solution to this matter is urgently required and that solution must come from the highest levels of American government.

We call on the Trump Administration to invoke all diplomatic and legal levers available to the United States to protect American companies from extraterritorial censorship mandates.

Our client reserves all rights."

I'm more optimistic. Open source and open weights will eat this whole space.

Training is capital-intensive, yes, but so far it appears that there will always be some entities willing to train models and release them for free. All it takes is a slowdown at the frontier for the open models to catch up.

This is why it always make me so mad about people who cry about how big vehicles are getting and why can’t we have the tiny thin dangerous vehicles from like 30 years ago instead.

Shut up. You’re just standing in the way of progress. Vehicles have to be bigger in order to be safer and more deformable, and they’re even safer for pedestrians. If they take up too much space on a road, build bigger roads. You cannot miniaturize automotive safety.

Paul Graham wrote an influential essay in 2001 arguing that online hosted software was going to be great:

https://www.paulgraham.com/road.html

The benefits that he described did come to pass, but the costs to user autonomy are really considerable. Companies cancel services or remove functionality or require updates, and that's it: no workaround and no recourse for users.

The hosted LLM behavior issue is a pretty powerful example of that. Maybe a prior LLM behaved in some way that a user liked or relied on, but then it's just permanently gone!

My son struggled quite a bit learning to read. He was very slow to do so, and it frustrated him quite a lot. But interestingly, once he did get it, he became a voracious reader, and he's never since scored below 95th percentile on reading tests. So his developmental dyslexia did not carry over into general dyslexia.

One of the interesting things about nvld, at least in his case, is that you would never know he had a learning disability by talking to him. He comes across as a smart, mature, knowledgeable young man. Mostly because this is what he actually is. But when he does struggle with something, it is often interpreted as him not trying or being lazy.

That's the thing with activities anyone can do - pretty much anyone does. And 90% of everything is... not great. I think a lot of those doofuses on LinkedIn just portray some level of success when in reality they're desperate for business, at least some folks I spoke to that are very active there were like that. But that's anecdotal evidence. Depressingly, just how some folks succeed with just a good offering, some folks just succeed with good marketing. But I suppose if you manage to be reasonably good at both, you have a good chance to succeed.

> In many ways, the tuple (BBC Micro, Acorn Computers, arm) is analogous to (IBM PC, Intel, x86).

There was a radical difference in the relationship between the two corporations in each tuple. In the BBC-Acorn relationship, Acorn designed and manufactured the computer; BBC just offered their brand, did marketing, and supplied some high-level requirements. In the IBM-Intel relationship, IBM designed and manufactured the computer, and Intel was the CPU vendor, with many other customers. The 6502s used in the pre-ARM BBC systems were from MOS Technology–or one of their licensees, such as GTE/CMD–so those companies were really the Intel equivalent here

> I'm more shocked that so many people seem unable to come to grips with the fact that something can be a next token predictor and demonstrate intelligence.

Except LLMs have not shown much intelligence. Wisdom yes, intelligence no. LLMs are language models, not 'world' models. It's the difference of being wise vs smart. LLMs are very wise as they have effectively memorized the answer to every question humanity has written. OTOH, they are pretty dumb. LLMs don't "understand" the output they produce.

> To them, if something is a token predictor clearly it can't be doing anything impressive

Shifting the goal posts. Nobody said that a next token predictor can't do impressive things, but at the same time there is a big gap between impressive things and other things like "replace very software developer in the world within the next 5 years."

This article is one of those “technically true” things I’m tired of hearing about from modern economics. It’s technically true we could retrain all white collar folks who lose their jobs to LLMs to work in blue collar work, it’s technically true that the glut of new folks wouldn’t cause wages to go down, it’s technically true that once we have all that economic productivity it could be redistributed to make everyone more prosperous.

As many a wise man has said before me, gdp doesn’t reflect prosperity on the ground, or put another way:

Two economists are walking in a forest when they come across a pile of shit.

The first economist says to the other “I’ll pay you $100 to eat that pile of shit.” The second economist takes the $100 and eats the pile of shit.

They continue walking until they come across a second pile of shit. The second economist turns to the first and says “I’ll pay you $100 to eat that pile of shit.” The first economist takes the $100 and eats a pile of shit.

Walking a little more, the first economist looks at the second and says, "You know, I gave you $100 to eat shit, then you gave me back the same $100 to eat shit. I can't help but feel like we both just ate shit for nothing."

"That's not true", responded the second economist. "We increased the GDP by $200!"

Autophagy research is all over the place and its hard to understand this stuff or make blanket statements, instead we just have to be flexible with it. Autophagy is always working and the ramp up happens pretty quickly for a lot of people. I think aiming for the 48-72 hour peak isn't helpful. Most people cant or wont fast that long. A lot of people on 16-18 hour daily fasts see benefits that suggest autophagy working well.

Also biology isnt computers, its not exact and all our bodies are very different. For example, say your standing autophagy rate is 3. 16-18 hours fasting its 7 out of 10. But at 48 hours its 10. The difference between 7 and 10 might not even be very meaningful on a practical health level. The difference between never getting to 7 because of "it takes 48 hours" thinking and never trying is then huge. Just a couple hours a day at level 7 autophagy or whatever could be life changing. I do about 14-16 hours a day and am happy I made that decision for myself. I do see benefits that are real seeming to me.

From what I've seen there's no real downside to 14-18 hour daily fasting and in theory incredible benefits. Its also worth mentioning for a lot of people just sleeping with an empty belly means a higher quality of sleep, so there's secondary benefits as well. Your gut 'taking a break' during those hours may also be another benefit in terms of gut health as well, but I'm more skeptical of that claim.

As a recently laid off tech worker, I was excited to have a recruiter contact me regarding what seemed like a dream job. After passing an initial phone screen, a face to face interview was scheduled. I spent several days preparing. On the day of the interview, I took the train into the city and had a 4 or 5 block walk to the new company's office. While walking, I noticed a scraggly dog laying in the alley. I was pressed for time, but stopped to get some food and water to give to the dog. He was very appreciative, barked playfully, and licked my face. I continued on my way. When I got to the office, I signed in, took the elevator to the 7th floor, and opened the door. Imagine my shock, the dog was the interviewer. <-- This is the kind of nonsense I generally see posted on LinkedIn, perhaps only slightly exaggerated.

C'mon, this is not hard.

What takes more time to master: Learning how to be a competent woodworker, so that you can build a piece of complex furniture from scratch, by hand. Or learning how to punch in instructions, following templates.

The first can take years to master, the latter is done in mere months. You don't need to be a master woodworker to operate a CNC machine.

With LLMs, we're now at the point where non-programmers can get working CRUD apps. Nearly impossible only 2 years ago. LLMs are encroaching what is the bread and butter to thousands of webdevs out in the world.

You can still be a rock star dev that writes world class code, but you better be working for employers that value it - because AI will force prices down. When customers discover that a $20 subscription, or service can create them things that would previously cost thousands of dollars in dev money, there's no way back. Once that cat is out of the bag, you won't get it back in.

Emulating a physical TPM doesn't always help when you cannot get a valid certificate signed by AMD/Intel. These are stored on the TPM and cannot be easily dumped. You'll want to passthrough your PC's TPM to the VM rather than emulating one.

https://www.reddit.com/r/linux_gaming/comments/1mkb3s8/under... talks about an example of a timing check that games use to detect running in VMs. There's additional checks besides this, but give you an example of how it's possible to block VMs.

In the absence of actually lengthening the telomeres, everything falls short in the anti-aging department.

Most lifestyle habits contribute to shorting the telomeres as little as possible, which guarantees good health no matter the age, but still aging, albeit slower.

Given the current technology trajectory, many people including me, think that we are very close to totally stopping aging, and even reversing it.

Sounds like "enshittification" to me: During the growth phase the offering is good, but as growth inevitably slows, most companies will extract value by other means: Cutting costs/quality and raising prices are the most obvious and perhaps least nefarious tactics. There's companies that don't fall too far into this, but I think most successful ones do.
Show HN: Provability Fabric – From Guardrails to Guarantees for AI Agents

Show HN: Provability Fabric — From Guardrails to Guarantees for AI Agents https://mateopetel.substack.com/p/provability-fabric-the-saf...

Most AI “safety” today is just vibes. Prompts get hardened, heuristics stacked, dashboards blink green. But when agents can call tools, stream outputs, or mutate state, vibes don’t scale. You need math wired into the runtime.

Provability Fabric (PF) is a framework for proof-carrying behavior:

Spec-to-Proof layer → ActionDSL policies compile to Lean 4 obligations + runtime monitors

Provable Agent Bundles (PABs) → signed packages binding spec, proofs, SBOM, provenance

Rust sidecar → complete mediation of all events (call, ret, log, declassify, emit_chunk, emit_end)

Egress certificates → every output gets a signed verdict (pass/fail/inapplicable)

TRUST-FIRE test suite → stress tests for chaos, rollback, privacy burn-down, adversarial adapters

The core bet:

“Safety isn’t a setting. It’s a correspondence proof between your semantics and your runtime.”

Would love HN’s take:

Is this the right way to move beyond vibes toward falsifiable guarantees?

Should proof-carrying bundles (like PAB-1.0) become the standard for deploying agents?

What would it take for you to trust an agent in prod — proofs, monitors, or something else?

If the "on the go" experience is important to you, i.e. you actually want some care and intention put into the phone experience. There are 4 apps I'm aware of:

- Happy Claude Code Client: open source (MIT) effort for a quality mobile app

- Omnara: closed source mobile app, $9/month

- CodeRemote: closed source mobile app, $49/month

- Kisuke: closed source mobile app, private beta, unknown price

If you know of others, I would appreciate a PR to update the table I put together, or just let me know and I'll add it.

There are more more desktop apps, probably because those are easier to design.

Many practical optimisation problems are less like "let's go hiking and climb a literal hill which we can see in front of us" and more like "find the best design in this space of possible designs that maximises some objective"

Here are some alternative example problems, that are a lot more high dimensional, and also where the dimensions are not spatial dimensions so your eyes give you absolutely no benefit.

(a) Your objective is to find a recipe that produces a maximally tasty meal, using the ingredients you have in your kitchen cupboard. To sample one point in recipe-space, you need to (1) devise a recipe, (2) prep and cook a candidate meal following the recipe, and (3) evaluate the candidate recipe, say by serving it to a bunch of your friends and family. That gets you one sample point. Maybe there are 1 trillion possible "recipes" you could make. Are you going to brute-force cook and serve them all to find a meal that maximises tastiness, or is there a more efficient way that requires fewer plan recipe->prep&cook->serve->evaluate cycles?

(b) Your objective is to find the most efficient design of a bridge, that can support the required load and stresses, while minimising the construction cost.

Ironically, the most prominent advances have not actually been in cryptocurrencies themselves but rather in the traditional financial institutions that interact with them.

For instance, there are now dozens of products such as cryptocurrency-backed lending via EMV cards or fixed-yield financial instruments based on cryptocurrency staking. Yet if you want to use cryptocurrencies directly the end-user tools haven't appreciably changed for years. Anecdotally, I used the MetaMask wallet software last month and if anything it's worse than it was a few years ago.

Real developments are there, but are much more subtle. Higher-layer blockchains are really popular now when they were rather niche a few years ago - these can increase efficiency but come with their own risks. Also, various zero-knowledge proof technologies that were developed for smart contracts are starting to be used outside of cryptocurrencies too.

This is pretty nice, though I'd suggest you call it a transparent syntax highlighter.

For https://grack.com/demos/adventure/, I used a hidden <input text> for something similar. I wanted to take advantage of paste/selection and all the other goodies of text, but with fully-integrated styling.

Like you, I found that standard text input boxes were far more interesting than contentEditable because they're just so simple overall.

I think there's probably an interesting middle ground here where you render real markdown with the textarea effectively fully hidden (but still with focus), emulate the selection events of the rendered markup into the textarea, and basically get a beautiful editor with all the textarea solidness.

RiscOS simply had to start the whole OS cycle from scratch, it wasn't as good as what was already available on the Amiga and it wasn't Unix. It was fun to work with if you came from the BBC Micro it all made good sense and was a step up. But when looking at it from a corporate angle it wasn't quite what you'd expect from a workstation and it didn't run anything that you needed right there.

> Paranoia about this is silly.

Having had to deal with some clients with slightly sensitive data, I wish. Photocopies and printed screenshots lying around in the open, CC data copy-pasted manually to other fields or to generic excel sheets because otherwise "it disappears and we can't book late fees" etc. Not even only the "random third-party" companies vetted and specialised in ID verification, but then they get a new support contract down the road, and a fourth- or fifth-party agent who had the cheapest offer now has remote admin access to those desktops.

Probability is low, true. But all it takes is one compromised access.

We all choose our battles probably.

Not all auto makers just up and decided backup camera are now a standard feature. Rather: it’s a regulation put in place by Congress. To assume that cars will continue getting the same level of steady safety updates also assumes that the regulatory environment of the next 20 years looks like the last 20 years. As opposed to a regulatory environment that looks like the last 20 months.
