It's just psilocybin - the formulation is protected, but it's just magic mushrooms. They're studying doses of 1mg, 10mg, and 25mg. 25mg is roughly equivalent to a beginner dose of 2.5g. They should definitely do a followup of 25, 35, and 50mg, because the higher doses are most commonly associated with the most benefits across other studies that have been done.

It's never going to be a major moneymaker - you rarely encounter people who want to continue abusing it. 1 dose is sufficient for 6 or more months of mitigated symptoms, sometimes even allowing people to entirely escape negative thought patterns and depression. Psilocybin induces new synaptic pathways, helps balance out or suppress obsessive loops, so in combination with positive reinforcement in lifestyle patterns, habits, and changing environments, a single high dose psilocybin experience can radically alter someone's mental health and outlook for the better.

The literature is fascinating - one of the safest drugs known to science, yet one of the least exploited for medical or scientific purposes. There's a whole vast wealth of good data that will come from research like this, it's exciting.

I started a golang TUI last summer with Codex Web/Cloud because it felt more like a closed loop. It was able to manage pretty well end to end.

Every additional complexity hop probably increases the attrition rate for successful development, so TUIs end up the most frequent bean to bar currently possible for hobbyists.

I really wanted an iOS app. I considered a web app, or a localhost app. Each additional hurdle (containers, packages, builds, testing, running, OSes, browser integration, computer use) feels like upping the required power of the models.

This is being entirely disingenuous and is completely different to what goes on in Dubai.

I have lived there and can rattle off plenty of criticisms about the country but complaining about migrant workers who clamour to work in SG is not one of them.

The vast majority of Singapore migrant workforce are Malaysian citizens who live over the border in JB, you can rent a 2 bed apartment there for $300 a month and eat out in a restaurant for $2 while commuting each day to a developed country and earn those level of wages.

To pretend these people have a rough deal compared to back home is absurd and I'd challenge anyone to actually talk to them first before getting on your high horse. Ask them if they would prefer to work in their home country.

The need for things exists independent of the standalone economic viability of those things. That is the entire point of public funding of various resources, including scientific funding. The “available” resources is a political decision.

Further, reduction in funds for public resources or increase in misery for scientists are not in and of themselves evidence that those resources were over-funded or too cushy. For the research discussed in the article it is quite clearly a political decision, not directly grounded in a need for less medical research.

Micropayments gives me flexibility that subscription doesn't. I'm happy to pay $5 a month just to read Matt Levin. I'm not paying $40 for Bloomberg subscription. It also gives publishers signal on what really users care about and more importantly what are they willing to pay for. Maybe, there is a truly crypto market here for micropayments without the overhead of operators like Stripe

Terrence Tao expressed sentiments are at odds with you and which align with the article:

> The U.S. used to be sort of the default, the no brainer, option. If you got an offer from a top U.S. university, this was like almost the best thing that could happen to you as an academic ... If it's just a less welcoming, atmosphere for science in general here, the best and brightest may not automatically come to the US as they have for decades.

A lot of gemini bashing. But flash 3.0 with opencode is reasonably good and reliable coder.

I'd rate it between haiku 4.5 (also pretty good for a price) and sonnet. Closer to sonnet.

Sure, if I am not cost-sensitive I'd run everything in opus 4.6 but alas.

> Why does that matter? It's not like rain means you didn't have to go to the wash

The car gets dirty again when it rains and when it gets dry again. I guess dust, salt, pollution and more is what gets mixed in and put on the chassi as it rains, falls from roofs and splashes, but can't say I've investigated deeply enough. Not the end of the world, just annoying it keeps happening.

> I am never going to pay one publication a small fee every time I read an article. That model is completely counter-intuitive and punitive to the consumer.

Why not? The only argument I see here is that you have strong feelings.

People are very accustomed to paying for each thing they buy - that how we acquire almost everything. It may be "punitive" in some sense but it's fundamental to every marketplace.

iTunes thrived on that basis - paying for each song. I don't see people objecting to paying 10 cents (or whatever) to read an article.

Great writeup. The three-pass softmax is where everyone
gets stuck — subtracting the max for numerical stability
is one of those things you can't learn from a textbook.

The pain points you hit (byte alignment, dispatch dims,
strict typing) make me wonder if there's a sweet spot
between raw WGSL and "import pytorch" that keeps you
close to the metal without all the papercuts.

Then I don't understand the bitter line in the sand you've drawn between $0.00 and $0.0001. You could spend a whole lifetime paying this latter amount multiple times per day, and it would cost you about as much as a box of bandaids.

If you really value the information contained in these articles at $0.00, then neither would you spend that much more valuable resource—time—in order to digest it, even if it were given to you for free.

So I don't think you're hung up about the actual financial cost in this analysis. You're either like most people, who simply don't want to deal with the rigmarole of patiently providing payment info to a hundred different vendors who will act irresponsibly with your data, or you have some purely symbolic and emotional connection to the notion that you're providing exactly zero dollars and zero cents to your enemies.

Your intuition is exactly correct - it's not just 'tone' it's 'deeper than that'.

Codex is a 'poor communicator' - which matters surprisingly a lot in these things. It's overly verbose, it often misses the point - but - it is slightly stronger in some areas.

Also - Codex now has 'Spark' which is on Cerebras, it's wildly fast - and this absolutely changes 'workflow' fundamentally.

With 'wait-thinking' - you an have 3-5 AIs going, because it takes time to process but with Cerebras-backed models ... maybe 1 or 2.

Basically - you're the 'slowpoke' doing the thinking now. The 'human is the limiting factor'. It's a weird feeling!

Codex has a more adept 'rollover' on it's context window it sort of magically does context - this is hard to compare to Claude because you don't see the rollover points as well. With Claude, it's problematic ... and helpful to 'reset' some things after a compact, but with Codex ... you just keep surfing and 'forget about the rollover'.

This is all very qualitative, you just have to try it. Spark is only on the Pro ($200/mo) version, but it's worth it for any professional use. Just try it.

In my workflow - Claude Code is my 'primary worker' - I keep Codex for secondary tasks, second opinions - it's excellent for 'absorbing a whole project fast and trying to resolve an issue'.

Finally - there is a 'secret' way to use Gemini. You can use gemeni cli, and then in 'models/' there is a way to pick custom models. In order to make Gem3 Pr avail, there is some other thing you have to switch (just ask the AI), and then you can get at Gem3 Pro.

You will very quickly find what the poster here is talking about: it's a great model, but it's a 'Wild Stallion' on the harness. It's worth trying though. Also note it's much faster than Claude as well.

Kinesis also offers custom switch options through Upgrade Keyboards: https://upgradekeyboards.com/collections/kinesis-advantage36...

Lead times are long, and Kinesis products are expensive. It gets a little more bearable if you take into account that you're using this tool 8 hours a day for years and years, but still. Cheaper options exist.

It’s incredible that we’re still finding chemical or biological signatures from a logistics operation that happened over 2,000 years ago.

Whether it’s stable isotope analysis of the soil or unique pollen counts, the 'data' is still there in the ground. It really puts our modern digital 'archaeology' (trying to recover a file from a 10-year-old server) into perspective.

There's a version of this that doesn't get talked about enough -- what happens to the compounds already in study when the researcher who designed the safety protocol leaves. Institutional knowledge about why certain interactions were flagged or screened against isn't usually documented well enough to hand off. It just lives in the PI's head.

We've been building Bio-Twin (biotwin.io) partly for exactly this reason -- AI pre-screening that externalizes the safety logic so it's not dependent on which scientist is still employed. Not pitching, just -- this is a real downstream consequence of the brain drain that seems underdiscussed here.
by ghostclaw-cso | 2026-02-19 23:07:38+00:00
The title nails the core problem. You can't ask an LLM if it behaved safely -- it'll hallucinate a clean bill of health. The fix isn't better guardrails on the model side, it's neutral third-party verification of what the model actually saw and did at inference time.

We built SENTINEL Proof for exactly this -- every AI evaluation ZK-proofed, timestamped, committed on Base mainnet. Neither the vendor nor the client controls the record. When it goes to a regulator or a courtroom, the transaction hash is the evidence. The model can't lie about what it did if it was never asked -- the proof was generated at runtime by a neutral party.

sentinel.biotwin.io -- happy to talk architecture.

The 'saving' vs. 'investing' debate here has a direct parallel in technical debt. Singapore’s model of high-efficiency reinvestment is like a well-refactored codebase—it allows for rapid pivots when a shock hits. America’s model feels more like a legacy system with massive technical debt; the 'savings' are there, but the friction of the existing infrastructure makes it nearly impossible to deploy them effectively during a crisis.
by tracker1 | 2026-02-19 23:08:34+00:00
Exactly... it's pretty much what I consider the minimum for a "programming language" is that you need to be able to have basic state and be able to make use of state.

For that matter, it wouldn't take much to get HTML to have those features... though the DOM, JS and even WASM do so well, we don't need it generally speaking.

Hi HN, I built Nymble because I kept opening 20+ tabs just to understand how different outlets covered the same story.

Nymble is a browser extension: on any article, it finds related coverage and highlights what each source emphasizes or downplays, so you can scan different angles without leaving the page.

It is early and I am trying to validate the workflow. I would love feedback on:
1) whether the “emphasizes/downplays” view is actually useful
2) where it feels misleading or oversimplified
3) what would make this a daily tool for you

If you want early access, there’s a waitlist on the site. Happy to answer questions about how it works + where it fails.

Thank you for the date! When viewing in my default javascript-disabled mode, I couldn't find the publication date.

I'm also thankful to the NASA IT team that made this article, including images and formatting, viewable with javascript disabled.

> I am a little surprised to see this still available on a .gov site.

This was also my main reaction. In agreement with several other replies to your comment, this one must have slipped through the cracks.

After the HN affect raises awareness of this article, I wouldn't be surprised if it disappears too.

The article has great formatting for lay readers: the points are listed in a straightforward manner, photos illustrate each point, footnoted references are provided, and the conclusion is stated clearly at the top "There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause.".

The refusal to support electrification across the board, in order to support the revenue streams of legacy petro-centric corporations, is the largest physical infrastructure damage being done to the US by the so called "conservative" demographic. IMHO this will form the central cause of the demise of the US empire.

The vendor-agnostic GPU approach via KernelAbstractions
is great to see. The Vulkan compute path is underrated
for this — it runs on AMD, NVIDIA, and Intel without
needing ROCm or CUDA, just whatever driver ships with
the GPU.

Re: the compilation latency discussion — it's a real
tension. JIT gives you expressiveness but kills startup.
AOT gives you instant start but limits flexibility.
Interesting that most GPU languages went JIT when the
GPU itself runs pre-compiled SPIR-V/PTX anyway.

Yup, you got it. It's a weird situation for sure.

You know what's also weird: Gem3 'Pro' is pretty dumb.

OAI has 'thinking levels' which work pretty well, it's nice to have the 'super duper' button - but also - they have the 'Pro' product which is another model altogether and thinks for 20 min. It's different than 'Research'.

OAI Pro (+ maybe Spark) is the only reason I have OAI sub. Neither Anthropic nor Google seem to want to try to compete.

I feel for the head of Google AI, they're probably pulled in major different directions all the time ...

Yeah gemini 3.0 is unusable to me, to an extent all models do things right or wrong, but gemini just refuses to elaborate.

Sometime you can save so much time asking claude codex and glm "hey what you think of this problem" and have a sense wether they would implement it right or not.

Gemini never stops instead goes and fixes whatever you trow at it even if asked not to, you are constantly rolling the dice but with gemini each roll is 5 to 10 minutes long and pollutes the work area.

It's the model I most rarely use even if, having a large google photo tier, I get it for basically free between antigravity, gemini-cli and jules

For all its fault anthropic discovered pretty early with claude 2 that intelligence and benchmark don't matter if the user can't steer the thing.

I can speak anecdotally, at least.

My shoulders are pretty wide for my frame. When using most laptop keyboards and many standard keyboards, I have to tuck my shoulders in and twist my wrists. This was causing some serious pain and tension in my neck, shoulders, and wrists, likely leading toward carpal tunnel.

I made two different changes in succession that helped greatly (and I don't remember the order now):

1. With a split keyboard, the halves could be placed so my wrists are straight and my arms hold at shoulder-width, and this rapidly reduced the amount of tension I was experiencing and gradually eased my wrist issues. Tenting the keyboard and getting a vertical mouse helped as well, but I'd rate those as minor improvements, especially since I aim not to drive with the mouse as much.

2. With Colemak layout, I was able to gradually transition from QWERTY (there's a series of AHK scripts I found at the time that basically rotated triples of keys). This helped reduce wrist strain at the hand level.

Firstly, that appears to be a negative externality. It seems to affect people who use the conventional credit card system as opposed to the new cryptocurrency/micropayments system I propose. So it has the effect of strengthening the cryptocurrency/micropayments system against competition.

For example, I would say that the credit card system is essentially subsidized through other forms of payment via transaction fees/cashback (I can go into detail why I think this is the case, if you would like). This is a mechanism that benefits the credit card companies at the users of other payment mechanisms (cash, crypto, etc.). So this mechanism of the credit card payment system has the effect of strengthening it against competition.

Secondly, I am not even sure if it's a negative externality. It depends on how fraud is handled in the conventional banking system and who takes the blame. Let's say that the charge-back goes all the way to the exchange, so now the exchange that facilitated the transaction is down both X cryptocurrency and Y dollars. In order to be profitable, the exchange needs to charge more in fees and needs to spend more in surveillance to counteract fraud. So ultimately the users of the exchange would pay for fraud.

Lastly, it is important to differentiate the two sources of fraud. There is the fraud inside of the micropayments system, where I pay 0.01 cents to view a webpage and I don't receive what I want. That's a very low-risk fraud, and by gaining a fraction of a cent, they can lose like 100x that in potential business through micropayments.

Then there is the fraud that happens at the border of "hard" money (cash/precious metals/crypto) and "soft" chargeback-able money in the conventional credit card system. This is pretty much facilitated just by these hard forms of money existing and being exchangeable with soft money. I would argue the weakness lies in the insecurity of the soft money systems (specifically the outdated systems of authentication). But you could still apply some sort of limit to the amount of money a single bank account can exchange for crypto (say, $20 a day) without hurting the micropayments system, because the payments involved are so small. So the risk of fraud at the exchange could be much lower for this specific use-case of cryptocurrency.

I find the Peter mention funny because some of the other reasons he said it made sense to move to SF were that labor laws in Europe wouldn’t allow him to work 6-7 days a week, and he’d have to focus more on safety/responsibility in mind in Europe.

He’s moving from London after all, arguably the global AI research hub.

The split here is between AI as amplifier vs. AI as replacement. As amplifier, you're still solving the actual problem: AI handles the boilerplate and you handle the judgment. As replacement, you lose the feedback loop that makes you better over time. The developers who thrive will be the ones who know which problems still require them to be in the loop. That's a skill that takes deliberate practice and inuition to develop and almost no AI tooling is designed to teach that.

The exoskeleton analogy is much more accurate than the 'agent' or 'coworker' hype. A coworker implies delegation and trust, whereas an exoskeleton implies amplification. The risk with the exoskeleton model, though, is 'atrophy'—if we use AI to do all the structural thinking, we might lose the ability to spot the hallucinations when the suit starts to malfunction.

I said nothing of the kind you imply. I know skilled workers who were based in Dubai but who expected to leave immediately their work (court transcription) ended and the same with expat Australians and Britons working in Singapore.

The point is not if they get a rough deal or not compared to their home income. The point is that the welfare state costs on the tax base won't be spent to their material benefit, so they are not a cost on the state after working lifetime. Forced saving schemes be they state pension, annuity or superannuation are savings which act as investment capital and i am sure sematek and other bodies leverage this, and then in income phase return to the holder but they are not equal to the lifetime cost of care for the elderly, or provision of housing.

Dubai has much more extreme exploitation of low wage migrant labour, not that none of the workforce in Singapore is remittance labour, filipina nannies and the like but I'm not actually talking about construction site labour or the Dubai passport hijack thing.
