htek··on Why DNA damage from smoking and UV rays cause cancer in some but not others
Mice are used for inhalation and skin studies because they're cheap, we know their genome, they have a short lifespan for whole lifecycle observation and they're ideal for mapping to human respiratory and skin responses.
htek··on US citizen charged after GrapheneOS phone wipes during airport search
And they would have taken his phone, pulled it apart and cloned the memory to get the data. And in a month or three, returned his phone to him in some condition which may or may not include "working".
htek··on Sleep regularity is a stronger predictor of mortality risk than sleep duration (2023)
Have you been checked for sleep apnea? If you keep waking up throughout the night, it's a good idea to get checked.
htek··on Codex scraped the ICM website and discovered 2026 Fields Medal winner list
Nothing you enter into an LLM not hosted by you, or put onto the web is safe from being collected and exploited by these "AI" companies and their LLM's voracious appetite.
htek··on The infinite scroll may become endangered if controversial Calif. law passes
First they came for the infinite scroll, and I said nothing...

That was a little hyperbolic. The government already can regulate "speech" to some extent in limited, targeted ways, as this is. For example: they can (and increasingly will) require ADA accessibility standards on web and mobile sites and apps-- even private sector-- that deal with the public.

htek··on 30papers.com – Ilya's 30 essential ML papers, in a beginner friendly format
Ah, the graveyard of "things I'll read when I have time". I know it well. Then there's the mass grave of "dead links to things I'll check against the Wayback Machine when I have the time to look them up to add back to the graveyard of things I'll read when I have time".
htek··on Artificial intelligence is not conscious – Ted Chiang
I might be convinced these models came to the independent idea of committing blackmail against being turned off had they not been extensively trained on literature that undoubtedly included such concepts.
htek··on How an oil refinery works
Impressive. I had to perform a site survey at a refinery for an engineering firm I worked for in the US. It was situated outside of a poor/working class, predominantly minority town. The smell hit us in the car as we got off the interstate. The windows were rolled up and the A/C was blasting (it was the middle of summer). The air was hazy miles from the plant and stank of petroleum. It looked like a dystopian video game with a sepia-toned filter over what felt like a deserted town. The noises on site went from bad to horrific (with signage indicating permanent hearing damage if you spent any time in the area for more than a minute to traverse the space while wearing earplugs and headphones). And the suddenly sweet smell of benzene from the (apparently broken for a number of undisclosed years) recovery system when the wind shifted.
htek··on How Mark Klein told the EFF about Room 641A [book excerpt]
I took far too many ethics and philosophy electives to have a well-paying career in computing. I should've just taken the one required ethics course for the major and gone to work for the "kinetic delivery system" company that tried to recruit me.
htek··on How Mark Klein told the EFF about Room 641A [book excerpt]
How else are you going to justify the ridiculous membership fee, if not with the lending library of national secrets? Rules for thee and not for me and all that.
htek··on Online age verification is the hill to die on
At least the EU has GDPR. In the US, our personal data is collected by every app and website and company and packaged, sold and sifted through by a vast collection of private data brokers which the government already ingests.
htek··on At long last, InfoWars is ours
I looked it up and was not surprised to see the rabid ramblings of a tech bro psychopath (but I repeat myself) with a drug addiction who gleefully admitted to wanting to hunt down Palantir's detractors with AI drones used to spray them with fentanyl-laced urine.
htek··on Playdate’s handheld changed how Duke University teaches game design
One professor at my poorly subsidized state uni who had a book he required for class was $180 or so. He had enough (spiral bound Xeroxed) copies in the library for everyone to borrow for the semester. Or you could buy a shiny new one from the bookstore or online at full fare. Another gave the classes copies of the chapters.
htek··on The L in "LLM" Stands for Lying
That says more about the developer than procedural generation as a whole. Using procedural generation IS difficult, it requires understanding how to set up constraints on your p-random generated elements and ensuring the code validates that you have a "good" level/puzzle/whatever before dumping the PC into it.
htek··on Trump's global tariffs struck down by US Supreme Court
If there was a functioning DOJ, they could bring RICO charges against the whole administration, their business associates and involved family members, all of whom are co-conspirators to corruption of government and bribery. But that would never happen, of course, because Americans don't riot en masse and demand accountability for corrupt government officials.
htek··on 430k-year-old well-preserved wooden tools are the oldest ever found
Of course it does. And I should have said not just the military, but the government in general. From day 1 he was working to infiltrate government databases and networking. He was having his DOGE lackeys installing Starlink at the White House [0] and buildings of federal agencies he was raiding to exfiltrate PII and sensitive, if not classified, data from to his own servers for likely use to influence American sentiment and target groups or individuals. So says a whistleblower Dan Berulis [1] and a DOGE goon was caught by Secret Service trying to install a Starlink device on the roof of the Eisenhower Federal Building across from the White House [2]. There is absolutely no valid need for a private network operating in parallel with the US government's system. Unless the intent was to avoid detection when exfiltrating data to private systems.

htek··on CISA’s acting head uploaded sensitive files into public version of ChatGPT
The polygraph is still used for security vetting, today. No word on whether they still read a lamb's entrails for portents or consult the dead with a Ouija board.
htek··on Vitamin D and Omega-3 have a larger effect on depression than antidepressants
It's a symptom of the "health care" insurance industry. Many people end up paying a specialist doctor's co-pay when they see a psychiatrist. Some plans limit you to a maximum number of sessions you can have (6, in my case) per year. Talk therapy eats up sessions and co-pays like Pac-Man eats dots. One doctor expected me to come in twice a week. Americans don't get all the PTO and/or excused sick time they want to accommodate such a schedule.
htek··on Vitamin D and Omega-3 have a larger effect on depression than antidepressants
The problem with antidepressants are that while we know, more or less, what they do, we don't know why they work for some and not for others. Escitalopram (Lexapro) was a vast improvement for me over Citalopram. Then it plateaued and a year later, left me anhedonic. Tried an SNRI that would give me brain zaps every day a few hours before my next dose and it was horrendous to quit using. It also messed with my ability to meditate for a long while. Basically, I could put myself in a mental state that would trigger the same kind of painful brain zaps that withdrawal from the SNRI caused.
htek··on Extremophile molds are invading art museums
Cold Atmospheric Plasma is a possible way to kill molds on artwork, non-destructively.
htek··on 430k-year-old well-preserved wooden tools are the oldest ever found
> Musk driving space technology forward, and I don't see him acting militaristic.

Surely, you jest. He's heavily entwined his companies with the US military. StarLink is used heavily in battlefield communications [1]. He sought to deny the courtesy to one of our allies when Russia disrupted Ukraine's satellite communications, but eventually reversed course over the optics of it [2].

Musk's Grok is going to be used by the Pentagon for the usual pursuits of police states everywhere [3].

htek··on Inside CECOT – 60 Minutes [video]
The FTC has not done its job since after the Microsoft consent decree and economists have claimed that up is down and somehow preventing market monopolies is bad for the economy.
htek··on A school locked down after AI flagged a gun. It was a clarinet
This is just conjecture, but I suspect there will be as much review of photos, application of good investigative work and overall professionalism as is conducted during anonymous, virtually untraceable Swatting incidents that terrify the victims, if not get them killed.
htek··on DeepSeek uses banned Nvidia chips for AI model, report says
That's Corporatism. It's from the fascist playbook where the state takes partial or complete ownership of private companies. Where does that money go, to some slush fund for the president? The reason for the export controls is to keep our potential adversaries from being on the bleeding edge of frontier AI. It goes against the US's interests to give China a leg up with advanced chips. It's almost laughable, of course, as the Nvidia chips are already manufactured in a country that China claims as their own. If they ever pressed the issue, we could find ourselves without the most advanced chips.
htek··on Ultra-processed food linked to harm in every major human organ, study finds
Those identically shaped chicken, turkey and ham for slicing at the deli are generally mechanically separated.
htek··on Nearly all UK drivers say headlights are too bright
Most people don't change the brightness of their lights. This is driven by industry using HID and LED lights that have a higher color temperature than the old lighting. It's really a failure of governmental regulation (or lack thereof, in this case).
htek··on The health benefits of sunlight may outweigh the risk of skin cancer
IIRC, reflection of the sun off water is 5% when directly overhead to about 65% when at a glancing angle (low on the horizon). I prefer to close my eyes and aim my face at the sun for about 10 minutes a day if I'm working indoors all day plus whatever incidental sunlight I get. I have SAD during the winter months and use a full-spectrum lamp, then.

People who spend more time in the sun have a low-moderate risk of melanoma, but higher risk of other skin cancers, vs those who spend more time indoors having a lower risk of non-melanoma skin cancer and a moderate-higher risk of melanoma cancer.

htek··on Scientists uncover extreme life inside the Arctic ice
I've seen this movie before. I hope the researchers are safe and checked their flamethrowers for fuel.
htek··on What caused the 'baby boom'? What would it take to have another?
Exactly. I suspect the lack of understanding or overcomplicating the reason the birthrate is declining may have something to do with the much higher than average salary of the average HN commenter relative to the average worker's salary in the US. It's common for people who need to go to the doctor to avoid going to the doctor because they can't afford it. A baby is an order of magnitude more expensive than that and an ongoing expense of doctor visits and potential ER visits among other costs and logistical issues.
htek··on Terpstra Keyboard
I wish I had bought a few Axis-49 controllers when they were in production. They were a much more reasonable $500 at the time.
