I did the math myself at one point, but I lost the link. However, here's a reference for the same kind of thing:

https://pthree.org/2016/06/19/the-physics-of-brute-force/

The total energy output of a supernova is enough to count up to 2^220, making a lot of generous (invalid) assumptions. You'd need 2^36 supernovas to just count up to 2^256, never mind actually running SHA256. At minimum.

There are circa 2^38 stars in the Milky Way, and they're not going to all go supernova. Add in the actual cost of compute and it just isn't happening, not in this galaxy.

For 128-bit crypto we can look at a more earthly calculation. Using the same math as that article, but at room temperature, and taking the total solar irradiance on the Earth as an energy source, it would take this long to count up to 128 bits (calculated using Google):

((2^128) * (1.38064852 * ((10^(−16)) (ergs / K))) * (298 K)) / ((1361 (W / (m^2))) * (pi * (radius of Earth^2))) =
8.04911615 seconds

Definitely more on the plausible side, but we're already moving away from 128-bit crypto and there's a staggering number of generous assumptions being made here; we aren't going to be getting thermodynamically ideal computers using a significant fraction of the total solar irradiance on the Earth any time soon.

Just to give you an idea of how far away we are from that, looking at actual SHA256 calculations:

https://www.iea.org/data-and-statistics/charts/efficiency-of...

22222 MH/J is the highest, or 4.5 × 10^-12 joules per hash. That's a factor of 2^30 worse, so if we used the total solar irradiance of the Earth to power Bitcoin miner style ASICs, it would take about 272 years to go through 128 bits' worth of brute forcing something of similar complexity to SHA-256.

The factor is more like 2^36 relative to the first "temperature of outer space" calculation. That happens to be about the number of galaxies in the observable universe, so using current technology, it would take somewhere on the order of all the stars in the observable universe going supernova to power through a single SHA-256 brute force.
He certainly controls the public media and Democratic Party Covid narrative in the US. If you have that much power in your corner, your influence is vast.

Interesting. What about hiring people from the leading companies? Isn't that how a lot of knowledge transfer happens in all industries? Are non-competes enforceable internationally?

Of course. I guess, what I wanted to say is that anything is better than setting up a trap and just executing the guy, like the other commenter said.
I wasn't using China as a positive example, I was using it as a contract in the negative. As in they don't have freedom during COVID, as they're literally locked into their homes. The United States has had and continues to have "freedom" even in face of the mandates.

Yes. I like to see faces. I like to smile at my daughter and see her face and have her see mine.

Masks are absolutely corrosive to society. They should have stayed off last June.
Citation please. What children had this happened to? You can’t throw out fear mongering claims about terrible outcomes with no data.

Also, are you aware that children sometimes die from RSV and even the common cold? The problem COVID vaccines for kids are facing is that the problems from COVID in that age are so infrequent that they are essentially in the noise.

I think the very young child (<18 months) is at higher risk, though.
A friend got a head injury (kid kicked her on the ear pretty hard) and had to wait about 5 hours in the ER before they could see her, they sent her home saying it would be nothing bad. Two days later she went back and they concluded she had a concussion..
Slowly pushing the data wars into the public field of view. Kudos to Apple for pushing so hard on this front. Now to put some pressure on the FCC to have some rule making done about disallowing telecom interference in the data packets.
STEM is a category. As a whole, it's split pretty much 50/50.

I'm sure you can slice and dice it into subcategories and then pick and choose those that have a higher number of men, but I can do the exact same thing with those subcategories you arbitrarily exclude to create a mirror image showing how STEM is biased against men. But it's a silly game.

> On the other side of "ridiculous": 6 feet of "social distancing" wasn't enough to begin with

Its not enough for you as an individual.

But such a rule lowers the "blast radius" of who gets infected when a case comes up. People's breath travels like 20 feet. If everyone is 6-feet apart, you only get ~3 people in front of you sick.

If people are ~2 feet apart instead, you infect 300% more people.

There's a thing about big groups. What's good for the group isn't necessarily what's best for the individual.
Eh, some people where born and raised there. I don't really feel like I had any agency over the policies of the state of California despite it having been my home for the first 33 of my 34 years.

I would have loved to stay in California if I felt like there was any chance of fixing policy in the state (and relatedly fixing affordability of living there).
> In New York, hospitalizations among kids quadrupled.

In New York, hospitalizations among everyone more than quadrupled. So if kids quadrupled, they are doing better than average:

Quotes about staggering, flaming rocket ships aside, if you don't bother to normalize your data to a meaningful baseline rate, you're either not capable of objectively analyzing the situation, or you're trying to mislead.

(It's also worth pointing out that in NY, something like 40-50% of "Covid hospitalizations" are unrelated to Covid, per the state's own statistics [1])

And yet modern advances point to tech bros trying to limit the USERS power of that internet.

It's already impossible for a lot of people to host their own web server from their home, to own the media they purchase without it potentially being erased by the vendor at a whim, to opt out of social media without a massive social (and professional) hit and computer power is being wasted on shitty electron apps and built-in OS adware.

Oh, on the subject of computer power being wasted, on a global scale it's being wasted on crypto, another attempt by a bunch of elitist executives to invent something that allows them to invent a new financial system in which they're still on top, but allows them to more easily commit tax evasion and money laundering.

All of our tech advances have largely been from massive companies trying to add scarcity to a system we invented that absolutely doesn't need it. Can't copy a MP3, can't copy an EXE, and now, you can't copy a JPG.

Yes, we do in fact have to participate in these dumbarse discussions. The choice to simply walk away from these things, particularly AS a tech worker, is bullshit artistry.

FCBuild2021 Talks
You're aware that "unvaccinated" includes the vaccinated < 14 days after 2nd shot?

UK numbers show that only 1% of Covid-recovered people are reinfected, which is why the EU pass equated recovery with vaccination (which does not prevent infection or transmission).

It would be more accurate if US hospital data was separated into:

Fully vax
Partly vax
Unvax + Covid-recovered
Unvax + Covid-naive

Not necessarily. Life expectancy is affected by the most mortal part of your species: it might be that pigs’ hearts are fine, but they’re prone to cancers after a certain age.
Yes.

The "size" you are talking about is the "process node". It's basically a shorthand for how large the transistors are. These nodes are not fungible, once a chip is designed and a mask set is taped out it must be fabricated on that specific process node. Even if you have a chip designed on an older/larger node, it cannot be fabricated on a newer/smaller node without significant expense and delay.

Older nodes are generally in lower demand, although strictly speaking they are a tighter supply bottleneck, since nobody is incentivized to build fabs at older process nodes.

But the picture is even more complicated than this. Virtually all semiconductor fabs specialize in certain kinds of chips. Even at roughly the same process node, a DRAM fab cannot easily retool to make NAND, a NAND fab cannot easily retool to make logic (CPU, GPU, FPGA...), a logic fab cannot easily retool to make MEMS or image sensors, and so on.

In fact, not only are individual fabs tooled to make particular kinds of chips, but individual fab operators will generally have their own "design rules" at a certain node. So suppose that you have an ASIC you've been making at TSMC 22nm; just because GlobalFoundries has capacity at 22nm doesn't necessarily mean you can just have them start making your chips.
If you had a flock of a million birds and sixty of them died and you wrote a thesis with the term "mass die off" you would be laughed out of the room.

According to NatGeo "mass die off" is 90% of the population. I'd be alarmed at 6% die off in humans and not even be posting on the topic, but we are at less then 1%. For the unvaxxed.

"Killing each other off" just doesn't fit here.

And this is being obtuse about "these declarations" to avoid acknowledging the fact that the person at the top of this thread is correct: COVID, statistically, almost never transmits outdoors. It's been studied, multiple times, all coming to the same conclusion.
You don't but my government does.
>The only meaningful difference with high-end coffee is that those have a softer, smoother taste. Less bitter. That's it.

respectfully disagree, and i'm not even a coffee snob -- just a life long addict who doesn't analyze, just drinks.

Wine tastes like shit to me, but i'd never be so sure that my interpretation of it was correct that i'd try to explain why wine snobs exist. I understand there all wines have nuances that I may miss as someone who is inexperienced with wine and without a preference towards it.

Coffee , more so than most other plant products, has a wide variety of tastes. How could it not? It's a plant grown in varied areas with varied problems, varied soils, and then roasted or treated in varied manners.

We disagree, I understand I won't convince here, but I can confess my own experience : coffee is a spectrum of flavors , and not everyone has the tongue (or time) to notice -- but to dismiss it as 'pure boredom' is something I absolutely disagree with.

You don't need a 12kUSD espresso rig to notice that there are more than two taste profiles in the world of coffee.
RCS is a shitty system set up by a shitty telco industry. The protocol is behind what most countries in the world use already. I see it as just an attempt from the telco industry to start charging subscriptions for Whatsapp again, but about five to ten years too late.

iMessage would be fine if it wasn't for the shitty vendor lock-out. Everyone I know uses some kind of cross platform chat app, usually either Whatsapp or Telegram. It's sad to see the green bubble shaming that Apple's exclusionary tactics has created be of such influence in US social circles.
Even better, the "MI Drive" site (for Michigan road conditions) actually shows live webcam footage from many (all?) of the DOT plows.

A lot of people outside the US don't realize how new all our city layouts are. The majority of American cities were built out after cars came onto the scene. Did the cities exist before cars? Sure, but except for a few east coast cities, only with population numbers that could best be described as laughable.

While it 'can', it never has for me.
Not sure I understand exactly what you are saying

As for VR I think that's an excellent illustration of my point - we know that many people don't do well at 60FPS per eye in VR due to motion sickness. Move up to 90FPS per eye though and there is a massive improvement that I have seen first hand others. By the time you get to 120FPS the experience feels pretty damn smooth and while I would of course like to see more frames I am not convinced going a ton beyond 120 is really worth it performance wise considering you have to render that twice and the extra compute could be instead spent on the new shiny like ray tracing.

Luckily when I was working at a VR startup I was one of the few people that never seemed to get motion sickness so I became the test dummy for everyone's work - they would throw me in something they hadn't optimized at all yet that was only getting 40fps on a system with dual Xeons and quad Nvidia top of the line workstations cards and while it felt a little weird it for some reason never bothered me :-D

Can it do that after 5 years of use? At 5 degrees F? Can it charge in 5 minutes? Even the cheapest gas powered cars can do this.

This sort of performance may not matter to you if you only commute to work and back, but its the kind of performance that many people need on a day-to-day basis.
In the Netherlands at least, we use "familie" to refer to the extended family. To talk about the immediate family or one's household, we would use "gezin" (Although I think some parts of the Netherlands may use "familie" for the nuclear family as well? Not where I live, though.)

We don't generally distinguish between matrilineally and patrilineally related family, which is what the "cousin outside the family" was originally about.
>they have to solve all those solved problems again because companies that solved the problems won't share their solutions.

...because those solutions are the company's competitive advantage that China has tried to steal for years on end now? Not to mention in many instances those 'solutions' are owned by or access controlled by the parent country of said company, many of which view China as at the least a bad faith actor, and at the worst an inevitable opponent?

Pretending China hasn't engaged in the world's largest industrial espionage campaign over the last two decades, and then victim blaming the companies involved for not "sharing their solutions" with China is a perverse form of logic.
The only novel benefit, as you say, is "decentralized trust".

I've also pondered how these sorts of VC things work. Are they just targeted towards people fresh out of university who can afford to live cheaply? Seems a lost opportunity to hire experienced (expensive) people who can execute with no problems. For instance, what if say 2 experienced people went in on a startup, simply paying themselves out of eg that 500k - 125k each per year? For instance in australia that'd almost be competitive vs just taking a normal software job if you're experienced. I'm just curious how these things work :)
> The number of deer who've caught COVID19 in Ohio seems to suggest otherwise.

It doesn't suggest anything.

You're conflating two uses of the English word "effectively". One means "efficiently", which is the only one in use in the thread above, and the only one under debate. The other means "functionally" or "the effects are the same as", which is what you used in this single comment - but not even correctly. 1/3 of the deer population is not "effectively" the entire Ohio deer population in the sense that you meant it.

Furthermore, COVID19 does not spread effectively (in the sense of "efficiently") outside, as a comment that you've already read has pointed out[1]. 18 to 25 times less likely to spread to co-workers in an "open-air environment" (which kind of implicitly is still not like being in a park) fulfills the definition of "ineffective".

> Any reasonable application of Occam's Razor is that humans are spreading COVID19 to deer through some kind of outdoor setting.

Nobody claimed that there were no cases of outdoor human-to-deer infection - you were suggesting that the virus spread effectively outdoors in [2], which Occam's Razor does not support in the slightest.

You also moved the goalposts from "The fact that there's a bunch of infected deer means that covid effectively transmits outside" to "There's some outdoor transmission", and those two positions are completely different.

So, yes, Occam's Razor does support your (silently) revised claim in this comment, but definitely not the comment you originally invoked the Razor in.

In the U.S. it's mostly kids that aren't vaccinated at this point. Among people over 18 years of age, 73.3% have at least 2 doses and 86.4% have at least 1 according to the CDC. Two shots and a booster is obviously better, but the number of adults that haven't been vaccinated at all and haven't gotten Covid at least once is dwindling.

Covid seemed to be on track to have be almost entirely wiped out in the U.S. until Delta and Omicron came along, and now it's not clear that even 100% vaccination rates would be enough.
