Tbh I'm not sure but they've done accelerated dosage testing to simulate long term use by repeatedly exposing people to use of the machine over a more frequent period of time.

But mmWave really just is not dangerous. Current generation 5G cellular and WiFi standards are mmWave and they are just as harmless.

Molecular damage just starts showing up with THF/terahertz emissions band but mmWave is in the EHF and is has more than 10x the wavelength of THF (i.e. it is far wider/more gentle than THF). In a very real sense mmWave can't even interact with most of the molecules in your body.

mmWave can interact with the water in your body but at the levels it's being used it's only really useful for seeing the water. You'd needs orders of magnitude more powerful emissions than what these scanners use to actually cause damage at that frequency.

i.e. It's the difference between using the flashlight on your phone to see in the dark and using the concentrated light from solar-thermal heliostats to boil water or heat molten salt. No matter how hard you try, your flashlight is never gonna boil water.

This is a good analysis of the yen carry trade but i'd argue the causality is backwards. Record high margin debt in the U.S. is the root cause as it's a powder keg. The yen is just the fuse being lit. When system-wide leverage is this extreme, any funding sock (whether it's the BOJ rate hikes, hawish fed, or geopolitical event) can initiate the liquidation cascade. The yen carry trade is one source of that leverage but the fragility was baked in. If Japan didn't do anything something else would have cause the liquidation cascade, only a matter of time.

The real story isn't Tokyo, it's that Wall Street built a house of cards and ran out of steady hands.

I have a public ThetaEdge card that monitors margin debt and calculates the correlation with the S&P here:

The stocks of a lot of these SaaS companies were priced on the expectation that they could become the next IBM: become entrenched with the customer and then hike prices until their eyes bleed.

A lot of companies have been too smart for that, and a lot of SaaS offerings are too small to be truly entrenched. Arguably the investment horizon is too short (IBM took decades getting to that point).

The only real vendors who managed to become the next IBM are the cloud providers.

It is a shame that jart got control of @OccupyWallSt and occupywallst.com and never gave it up. It seems like her politics and views are very out of line with many of the people who were originally involved in that movement. Repurposing occupywallst.com for something like this compared to it's origin is a big disappointing contrast. https://web.archive.org/web/20111021162924/http://www.occupy...

Thank you, your comment made me aware of this event I didn't know. [1] I have found at least one concrete evidence you assertion is correct [2]: The Dusseldorf Agreement of March 16, 1939.

> The British historian Martin Gilbert believes that "many non-Jews resented the round-up", his opinion being supported by German witness Dr. Arthur Flehinger who recalls seeing "people crying while watching from behind their curtains". Rolf Dessauer recalls how a neighbor came forward and restored a portrait of Paul Ehrlich that had been "slashed to ribbons" by the Sturmabteilung. "He wanted it to be known that not all Germans supported Kristallnacht."

This passage is particulary eerie IMHO, since I've been reading "I don't condone this" of current world events over and over.

> In 1938, just after Kristallnacht, the psychologist Michael Müller-Claudius interviewed 41 randomly selected Nazi Party members on their attitudes towards racial persecution. Of the interviewed party members, 63% expressed extreme indignation against it, 5% expressed approval, and the remaining 32% were noncommittal.

Also particurlarly eerie to me. Yet the regime went on.

There's only ten possible guesses, and most people use their thumb and/or index finger, leaving four much likelier guesses.

Also, IANAL, but I'm pretty sure that if law enforcement has a warrant to seize property from you, they're not obligated to do so immediately the instant they see you - they could have someone follow you and watch to see how you unlock your phone before seizing it.

I don't know if even they know that they're looking for with the question as they marked it as experimental and optional but the explanation perhaps gives some hint:

"Optional: attach a coding agent session you're particularly proud of.
This is an experimental question for the Spring 2026 batch to give people a chance to show off their skills with AI coding tools."

Maybe they're hoping to gain some signal around a correlation between good AI coding skills and future company success?

Aww, then you missed the best part! Who wouldn't be head over heels for the opportunity to follow this financial advice and lose all of their "monopoly money" (funsie term for real cash!)?

Call To Action
This won't just be the big one. This could be the last one. If you've been preparing your whole life, knowing that something's coming, then this could be the thing you've been preparing for. One final opportunity to get the guys who did this. [...] The worst that can happen is you lose your monopoly money, but that's been happening anyway.

For everyone to make up their own opinion about this poster's honesty, here's where his quote is from [1]. Chosen quotes:

> CSAM includes both real and synthetic content, such as images created with artificial intelligence tools.

> It doesn’t matter if the child agreed to it. It doesn’t matter if they sent the image themselves. If a minor is involved, it’s CSAM—and it’s illegal.

I ran the command, looked at the report.
It said something like 300+ sessions are about database migrations.
That can't be its a new project I only had like 10 claude code sessions so far.

I asked Claude about it it looked into some files and this was its response:

> The "336" number was fabricated by the insights generation process. It doesn't exist anywhere in the underlying facets data. The insights generator appears to have hallucinated
statistics that sound plausible but aren't grounded in actual data.

The facets only analyzed 7 of your sessions, so any aggregate statistics like "336 database_changes" or "168 multi_file_changes" are made up.

So the whole report is fabricated, great. This kinda stuff just doesn't work (yet, maybe it never will).

If you live in the most pro-2A state, which is Texas, then you need not worry about this because not only will Texas vote Republican in a wildly lopsided fashion as usual, and not only will the state of Texas gleefully cooperate with Trump election interference, it is also the one place where ICE goons won't stalk the streets carrying arms and wearing skull masks because by statute and by jurisprudence Texas has already firmly established that it's reasonable to shoot such a person dead, due to doubt about their identity as genuine peace officers.

And, to be perfectly clear, it is reasonable to shoot that person on sight. But so far only Texas has codified it.

Certainly the higher your fiscal positioning, the better each recent decade has felt. Sure, we all have color TVs in our pockets [/s == "rich"], but can young people even afford to educate themselves in this economy?!

I know some very poor (and rich!) doctors and lawyers. Student loans and privatized healthcare are both evil within the USA — they can capture/demoralize just about any professional.

It’s nice, but the previous version wasn’t actually that great compared to Parakeet for example.

We need better independent comparison to see how it performs against the latest Qwen3-ASR, and so on.

I can no longer take at face value the cherry picked comparisons of the companies showing off their new models.

For now, NVIDIA Parakeet v3 is the best for my use case, and runs very fast on my laptop or my phone.

Author here. Happy to answer questions.

The problem: when you have multiple LLM agents working together and something fails, which agent is responsible? Traditional RL gives you one reward at the end, so all agents share the blame equally.

Our approach: an external LLM (we used Gemini) watches each agent's actions and tool outputs, then assigns per-action scores. When agent 3 crashes because agent 1 forgot to save a file, the coach traces back through the tool outputs and blames agent 1, not agent 3.

This gives you dense training signal without needing ground truth labels. The coach provides the supervision.

Practical angle: you use the API calls only during training. Afterward you have a team of local models that run offline. We tested with Qwen and LLaMA base models.

Results: +17pp on AIME math competition, +38% F1 on Kaggle-style data science tasks.

Hardware requirement is 2-8x 80GB GPUs depending on model size. Code is MIT licensed.

The framework is general - plug in your own agents, your own task, your own coach model.

I was the one who registered it. Occupy as a movement has always been inclusive of people with different points of view. My job running the website and twitter has always been to give the people a voice. I think that's important, don't you? The only guy with more credibility than me in Occupy is Micah White but he's been growing vegetables in Oregon ever since he visited Davos a few years back. So I'm the best you've got.

Here's my take: the bigger picture is one of "lessening humanity" - and it's death by a million paper cuts. Social media is one of the bigger cuts, but it's an awful lot of other things as well.

Being on screens all the time - especially when out and about (and whether it's social media or maps, it doesn't really matter) - means less casual conversation, less "hello, how you doing", less banter, less touch points with real people. It means toddlers look up out of their prams and can't meet their parents' eyes, it means you don't smile at strangers, or exchange a common glance about something trivial. It means kids don't get to sit in pubs with their parents and have to "do adult conversation". It means if you're in a situation as a teen and you're uncomfortable, you just reach for your phone instead of reaching out to the next awkward teen, who might just end up being your lifetime friend.

And then beyond that there are infinitely many takes-away-the-humanity cuts. Even something like this: once upon in our country you could buy a parking ticket for a space in a car park, then what typically happened when you got back to your car with time to spare is you then pulled up next to someone and offered them your ticket for free. This shit doesn't happen now - spaces are tied to number plates (because: profit), and so another little touchpoint with other humans is eroded.

Getting hold of many of the companies you use is becoming harder, through profit motives / AI chat / whatever - high street banks disappear, and immediately there's a whole source of contact that disappears.

We got a deal on our post-wedding train journey 25 years ago because we did it face to face with a guy in the station, and when we got chatting about the occasion and he discovered it was our wedding, he upped our ticket to 1st class. No such luck now, when you order all your tickets online, and the customer support is outsourced to somewhere a thousand miles away.

Real people are for the most part lovely people, and their motives are 95% aligned with each other - love your family, help people, be generous, be kind - but the more time we spend slipping behind digital facades, being taken away from human contact through these many papercuts, the worse things are likely to get. IMO.

Look at what happened to Jacques Baud because he criticized the EU on the Ukranian war and is now considered a "pro-russia" and propagating "disinformation". [1]

I read what he wrote ("L’art de la guerre russe, comment l’Occident a conduit l’Ukraine à l’échec"), you can download it temporarily here : [2].
His book is absolutely not pro-russia nor pro-EU.

> This may prove out if after 5yr+ of it being banned or limited, nothing changes in the youth (et al.) -- that would be my prediction.

You're speculation here could be a counterargument to Jonathan Haidt's meta studies on the effects of social media on teenage girls, if you can supplement your speculation with a better explanation for the increase in major depressive episodes in the time range he cites than the correlation with Instagram use.

For this article, however, all the participants are aged 18-30. Using it as a jumping off point to paint all concern over social media as a "moral panic" is reductive and unhelpful.

>> From now on, every time anyone says anything about Iran, I'll be pushing the narrative that "whatever Iran did, it was to defend itself".

> Israel was actually attacked

I was responding to your claim that Iran was defending itself... Whether or not Israel responded disproportionately to October 7 (it did), I don't think it's fair to say Iran's actions are "self-defense" in the same way that Israel's war was self-defense.

I am on the opposite side of what you are thinking.

- Blocking access to others (cursor, openai, opencode)

- Asking to regulate hardware chips more, so that they don't get good competition from Chinese labs

- partnerships with palantir, DoD as if it wasn't obvious how these organizations use technology and for what purposes.

at this scale, I don't think there are good companies. My hope is on open models, and only labs doing good in that front are Chinese labs.

I believe Perplexity is doing this already, but specifically for looking up products, which is how I use AI sometimes. I am wondering how long before eBay, Amazon etc partner with AI companies to give them more direct API access so they can show suggested products and what not. I like how AI can summarize things for me when looking up products, then I open up the page and confirm for myself.

Billions of people don't use calendar apps so they're useless; just remember your meetings.

Billions of people don't use todo list apps so they're useless; just remember what to do.

Billions of people don't use post-its apps so they're useless; just remember what you're going to write down.

Billions of people don't have cars; just walk.

It's definitely lead.

But when you do look at the details it doesn't look like the results point to the measured lead coming directly from gasoline itself.

Just as likely if not more so coming from the neighborhood lead smelter that operated over a period of decades where the phaseout probably overlapped from both mineral and gasoline sources, in step with the regulations.

These are rare samples but I wonder if it would be possible to determine how much lead was on the outside of the hairs which could be expected to settle from the atmosphere, compared to within the biological matrix itself which could have been incorporated metabolically?

And in a ubiquitous TEL-using environment, would that form of lead build up more so on the outside of the hairs or the inside?

With or without a lead smelter in the neighborhood?

There are two separate concerns here: who the credentials are associated with, and where the credentials are used. IMDS's original security flaw was that it only covered "who" the credentials were issued to (the VM) and not where they were used, but aforementioned IAM conditions now ensure that they are indeed used within the same VPC. If a separate proxy is setup to inject credentials, then while this may cover the "where" concern, care must still be taken on the "who" concern, i.e. to ensure that the proxy does not fall to confused deputy attacks arising from multiple sandboxed agents attempting to use the same proxy.
Show HN: Fast Sudoku solver that enumerates all solutions

Hi HN, I built a Sudoku solver web app focused on speed and correctness.

It solves standard puzzles quickly, but it can also handle ambiguous puzzles: instead of stopping at the first solution, it enumerates all valid solutions and reports the total number of solutions.

I built it mainly to explore performance and edge cases.

The author is implying that BoJ can/might/will cause appreciation of the Yen, which will force folks who are short(borrowing Yen) to buy USD assets to go underwater, forcing liquidation to pay back the Yen, and appreciating the Yen more. It's possible but there is no guarantee it would be a disruptive feedback loop or this year or etc.

If you believe them, then you can hedge buy either shorting TLT(betting treasury yields will rise), or going long Yen (e.g. FXY shares/calls).

I bought some FXY calls but just enough to hedge the Yen prices of my upcoming Tokyo trip in case they're right.

Basically anything goes with this administration, what's going on in the dark but will come out after 2029 will probably be outrageous, just imagine what he's got the CIA doing

They just seized six-year-old state ballots, with an incorrect illegal warrant, outside statute of limitations, with the agents calling the President in the middle of the action

By the way just a reminder they don't need any warrant at all to read any of your emails that are over six months old and you'll never know it happened, it's why the Clintons kept their email server in their basement because he signed that law and knew not to keep them remote

I mostly agree with what you said, but disagree on one point:

> Optimism is the precondition for doing good.

It is still possible to do good when things are bleak and there is no possible way out - just because doing good is the right thing[1]. Optimism helps a lot for morale, but is not a precondition.

The Iranian government is responsible of all sorts of human rights violations, and also for the drought (at least partly), but the economic collapse was triggered by the US.

Bessent said so at Davos:

"President Trump ordered our Treasury and our OFAC division (Office of Foreign Asset Control) to put maximum pressure on Iran. And it's worked, because in December, their economy collapsed. [...] So this is why people took to the street. This is economic statecraft". https://youtu.be/VQQXLnXlWqY?t=1722

Is this how America helps dissidents? Make them so miserable they can't bear it anymore? Anyways, it never works. It just makes civilians more miserable and the government more repressive. Look at Cuba or North Korea.

The reason why virtualization approaches with true Linux kernels is still important is what you do allow via syscalls ultimately does result in a syscall on the host system, even if through layers of indirection. Ultimately, if you fork() in gVisor, that calls fork() on the host (btw fork() execve() is expensive on gVisor still).

The middle ground we've built is that a real Linux kernel interfaces with your application in the VM (we call it a zone), but that kernel then can make specialized and specific interface calls to the host system.

For example with NVIDIA on gVisor, the ioctl()'s are passed through directly, with NVIDIA driver vulnerabilities that can cause memory corruption, it leads directly into corruption in the host kernel. With our platform at Edera (https://edera.dev), the NVIDIA driver runs in the VM itself, so a memory corruption bug doesn't percolate to other systems.
