power dissipation scales sublinearly in body mass, scales roughly as mass^.75

humans can dissipate 360W easily, though not necessarily comfortably.

that being said, the power usage is high. assuming uniform absorption, 4w/kg works out to roughly 200mw in the brain. here's a neuro paper that sets an optimistic limit at 40mw.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3807567/#B34

OTOH, we pump a lot more than that (relative to mass) into fly brains during imaging, although they're not expected to survive much longer than the imaging session. the laser in our lab is about 1w, after losses from the optics path and pulse picking, the power on the brain is usually around 20mw

"you need a trusted third party to save you from yourself and enforce the rules" is the complete antethis of what blockchains are all about. Some real doublethink there that you think there can't be ownership without that.

> Currently, the supply of no-code developers and agencies is far greater than the demand. Anecdotally, I'd estimate in the high hundreds or low thousands of entities explicitly marketing themselves for this service. Then when it comes to ones who've worked on apps that have scaled 2-10x farther than yours (assuming you have a few thousand rows in your primary database table), there are far fewer. Most of the freelancers experience is centered around prototyping. All of these variables mean you'll be quoted in the range of ~$150+/hr for these freelancers.

> Now looking at a code-based developer (like one who builds apps with Node or Rails apps), you can hire great ones for $50-100/hr. This is simply because there are millions of developers out there.

The Hanoi Hilton has been "sanitized" significantly over the years, as have the war museums.

The War Remnants Museum in HCMC is a must see for people interested in the history. But it went through several versions as Vietnam sought to restore relations with the US. It was originally called "Exhibition House for US and Puppet Crimes" in 1975, then changed to "Exhibition House for Crimes of War and Aggression" in 1990, then prior to US/Vietnam relationships normalization it was renamed as it is today.

Plenty of the exhibits have had their language modified as well.
Organic chemistry is covalent polar bonds, which don't require ionizing radiation to break. Emag can also effect biochemical processes in ways other than simple bond-breakage[0]. The brain is an electro-chemical system. Persistently nudging the electrons this way instead of that can also have a significant effect[1].

Yes I had a dentist who told me all of a sudden "you need 3 crowns" and I was like "bwah?" . Just 6 months before I was notified he was happy I hadn't had a cavity the 6 years I'd been seeing him. Naturally I went to another dentist who told me my teeth were fine and to not go back to the other dentist for anything let alone crowns but he said that was just his opinion as he didn't know the dentist personally. So I switched over to him. He took the time to point out on xrays from people who had decay bad enough to get crowns and that my teeth were nothing like those.

We have plenty of real-world experiments. Military radio operators, research station personnel, air-traffic controllers. Even food-service personnel that work near a frequently in-use Microwave. They all have orders of magnitude more RF exposure than the average person and yet no statistically significant difference in health outcomes has been found.

Contrast this with employees who worked closely with leaded gasoline, ionizing radiation, asbestos where the statistical signals are overwhelming.

>You asked what they do.

I asked for their ostensible justification. A valid answer should not involve making up a justification I never referred to, with the implication I had done so, with you refuting said justification, even if other people proffer said justification.

And the reason that I asked, was because the first reply eye-rolled at the problem I ran into, and then (seriously, as best I can tell) suggested I should have solved it by nesting a VM within the existing VM to control the dependency chain that led to the problem — even though that was what the first VM exists to solve!

To clarify, here is that (dubious) reply again:

> That's not what containerization is about as can be easily demonstrated by simply running your container on a kernel that's built without some config option you rely on.

That is, surrounding the container by a controlled environment would avoid the problem… but I was already controlling the environment by a VM that exists to solve that problem! Hence, (sardonically) wondering what the first one is accomplishing.

> The most useful feature is they reduce the pain associated having negligently-large build and runtime dependency trees.

No, the most useful feature is locking down a machine spec that Just Works. When I have to go and debug things about that machine that suddenly fail, for reasons Docker (not the machine) introduced, I lost the most useful feature.

Justification? For what? Seems like you're the one who feels entitled for something, it's you who needs justification.

> and then (seriously, as best I can tell) suggested I should have solved it by nesting a VM within the existing VM

You were the first to suggest anything like that. My answer did not offer any suggestion for solution at all, read it again.

> No, the most useful feature is locking down a machine spec that Just Works.

That's not a feature Docker ever had or intended to have. Seems you have misunderstood something about what containers actually are. They're very explicitly not "virtual machines lite", and it sounds like you want an actual virtual machine instead.

I am still confused why one needs to produce a document as "program" as opposed to set of pixel to be printed. If we know the page size in advance (which we do while pressing the print button), I would expect document program rasterizes it and so "print anything" can be achieved pretty simply. Why they needed to invent a new programming language called postscript?

One doesn't have to ditch all "western food". Just being sensible with it is good enough:

- ditch plant fat for animal fat

- avoid excessive sugar

- eat real food (no fake milk, meat etc.)

- stop eating vegetables, specially raw vegetables

Food is one of those things I take an ultra conservative stance on. The food industry has made eating literal poison (plant seeds, plant oils, spinach, brussel sprouts etc.) seem healthy with corrupt research and marketing.

You can't just take a food ingredient from one culture, throw away the indegenous preparation techniques and eat it completely different way and expect it to work. Take spinach for example. It comes from ancient Persia where it was added to a meat stew... you can't eat that raw. Spinach has high oxalate content... which gets reduced when you cook it for a long time. The remaining oxalate binds with high calcium in the meat stew and the resulting dish has no oxalate content at all.

Oxalates are one of the anti-nutrients, which are phytotoxins that plants use to avoid being eaten... Anti-nutrients in particular attack animals by affecting essential nutrient absorption. Indegenous preparation, which has evolved with the cultures, has ways to manage these toxins or counter them with some other ingredient which makes it edible. You can't do away with those preparation techniques.

I think the real meat of the article is further down, where they discuss replacing the Haber-Bosch process. That's what the article really ought to be about. Haber-Bosch is a huge emitter of CO2, and our industrial agriculture depends on it. That they intend to replace methane with ammonia would be nice, but regardless of that, if this Tsubame process can be made to work, it will have applications beyond that.

I was asking to clarify what your very confusing sentence meant. Because it seemed to be saying that, if I define a VM to use OS 1.2.3, because I know my app will work with that version, then my app on that VM should cease to work when 1.3.0 is released. And that seems dubious.
Not necessarily. I bought a very expensive cat toy robot that had a companion app. The company that made it didn’t just hide the app, they delisted it entirely. When I upgraded to a new phone, the download links were dead. It started me down a journey of coding my own replacement and reverse engineering the device’s firmware and BLE protocols which was a fun and rewarding experience. But, the fact that this was even necessary really stunk.
But how does purchasing assets by the wealthy (what you call hedging) produce inflation?

Inflation can only be produced if the demands for goods and services cannot be met and the price rises as a result.

Asset price increases are not inflation. A house's price going up is not inflation. Rent going up is. A house's rent is only indirectly related to the price of the house - there's a lot more that directly affect rents such as population growth or movement of people, changing preferences (some people might used to have house mates, but now prefer to live alone due to covid etc).
Meta investors brace for a difficult quarter
It's not for this particular study, but here is a possible mechanism for RF harm that I've been wondering about for a long time, and it drives me up the wall that people think I'm crazy for mentioning it. I'm also tired of the "it's not dangerous unless it's ionizing" dogma.

1) we know DNA is an electrical conductor. This is work by Jackie Barton, et. al, Caltech, she's been talking about it on the talks circuit for about 10 years but the papers are now coming out.

2) it seems like DNA error correcting enzymes use electrical potentials and current (or rather lack of current due to mutations causing geometric disruptions in DNA and "opening the circuit") to reduce the search space and make mutation repair more efficient.

3) high frequency RF can induce current in DNA.

4) it's important to note that this mechanism (RF can jam error correction) does not itself cause mutations so standard tests like the Ames test, blasting mice with RF, or related, will miss the mechanism, especially in well-controlled lab environments. An experiment would need to be set up to directly test error repair. Yeast might be a good model species since there is a comprehensive knockout library so you could see if the relative repair rate is unaffected in repair-deficuent strains.

Anyways. It should be a relatively easy Nobel prize if someone wants it. I'm not a scientist anymore, so I don't really have access to what I need to do this.
Isn't Facebook known for hiring full stack or is that no longer the case?
At least in the United States, anyone can create a credit score. There is VantageScore (the one you get for free from CreditKarma or your bank/credit card), at least 20 different versions of FICO, JSS Scorelogix, LexusNexus RiskView, Equifax FICO and RISK, ChexSystems Consumer Score, PRBC, and a million others.

You have a right as a consumer to the underlying data from the credit reporting bureaus, but not the proprietary algorithms that determine risk.

I understand the desire for transparency, but at its core credit scoring is fraud prevention. It is like asking Visa to explain what criteria they use to determine if a charge is fraud, which predominately helps the people trying to do the frauds.
I made the choice to use Firefox because of the monopolistic direction that we're headed, but I think it will become harder and harder to argue for Firefox.

I wonder if there is another way to create an information network that simplifies the user experience by scraping website code and reformatting it into a simple template with defined ux-patterns like navigation, font, text size, colors, buttons, links, media, etc. and excluding unwanted content like ads, filler bg images and such.

So basically creating a design system that you apply to all websites. The scaping/tagging would need to be smart and there would probably be a need for separate templates for some use cases (could twitter work?) but maybe the focus should be on information-driven sites like blogs, wiki, search, media, etc.

Are there any small (affordable, energy-efficient) switches with those speeds? Say, around 8-24 of the 25G lanes? You can buy a dual-port SFP28 card for 250 EUR by using the QNAP "accessory"[0] which is just a ConnectX-6 Lx EN with a fan to work in the NAS systems they market it for.

This is quite efficient due to the PCIe4 support not hogging many lanes (half of the 8 lanes can be enough depending on usage), but to use the speed one needs a 25G switch. Is the cheapest way just an Ryzen with 5 of these directly attached to the CPU, and running routing on the CPU via DPDK?

I'm 36, and I've had 32 cavities filled in my lifetime. I can't stand the procedure every time, and it's been heartbreaking for me not to be able to pinpoint why I've had so many cavities. I'm vegetarian, and I don't drink soda or alcohol. I brush regularly but should probably floss more. I do drink a lot of coffee and a lot of water. I completely avoid any candy and processed sugar (except for the occasional bit of something sweet in a restaurant dessert once or twice a year). I also eat a lot of acidic fruits and vegetables like tomatoes, lemons, limes, and pineapples.

Most were in my early teens (I had eight filled at once one time) so I was convinced it was the dentist racketeering and my parents wouldn't let me out of getting them filled. I should note my parents have a similar diet and a similar amount of major dental work. The handful of cavities I've had in adulthood have been major blows to my mental health.
Part of the point was that it was device independent, and simple rasterization wasn’t practical for printing on both low end office printers and the highest end commercial printing imagesetters.

Definitely not trolling. If you don't know how to prepare vegetables in indegenous culture that you got it from, you are better off not eating it.

Also, even if you did follow indegenous preparation methods, the food industry may have changed the plant by artificial selection or genetic modification such that the indegenous preparation is not as effective, so you're better off ditching them anyway.

Vegetables have significant phytotoxin content without significant nutrient content, specially in forms bioavailable to us (eg. a lot of carotinoids in carrots, except we are terrible at converting that to Vitamin A... we need the retinol form, readily available in milk, eggs, fish, meat etc.).

Plants are living beings and don't want to be eaten. They can't fight or flight so their defense is toxins. We have domesticated some of the plants and learnt how to remove those toxins over thousands of years... but if you don't know how to do that effectively, you're better off not eating them.
Many accounts sat the in the UK in the early 20th century dentistry was still so expensive that some people chose to have all their teeth pulled to spare themselves a lifetime of pain. Having all your teeth removed was considered the perfect gift for a 21st birthday or a newly married bride. My mother-in-law had her teeth out under this practice.

The foundation of the NHS in 1948 made dental care affordable for all and in the first nine months four million cavities were filled and queues formed outside surgeries.
