I think it makes sense that people who, due to trauma or other lived experiences (in addition to those who are genetically predisposed), have a brain chemistry that leaves them not feeling as well as they could, would be more vulnerable to getting addicted to substances that make them feel better (or ”normal”, even).
Not really true.

It’s widely accepted that the average intelligence is the same for male and women, but the variance is larger among men.

Of course women are capable in chess, and there are women capable of beating nearly everyone with extreme ease.

However, when looking and the very tail of the distribution, you will find mostly men due to the higher variance.

Hence, more men Nobel prizes, more man chess champions, etc...

I am not ruling out societal factors, but way too many people today rule out biological differences altogether!

I'm not sure I agree. Of course, Fred has invested in Carta, and he wants to push Carta X.

But a stake in a company is absolutely different than a fungible sport ticket. He should know, as he has also invested in non-fungible tokens in the Blockchain (cryptokitties). [0]

Startup equity is not exactly fungible. Plus, startup equity is an incentive for founders and early employees to work hard and smart to make their company successful. Giving that incentive away too soon might reduce the chance for the company to become a big hit one day.

Wind turbines have no intrinsic problems in extreme cold (cf. the Nordic countries, for example), but you have to make the investment to weatherize your turbines.

Texas didn't prepare properly. Perhaps because they didn't want to spend the money, or because the people in charge think climate change is not real and won't affect them. I wonder how many "100 year" storms it is going to take for the latter to change. Probably more than just this one, though.
wouldn't hashing be mostly int operations, while 3D graphics would be FP32? I dunno if they still do this, but nvidia used to artificially limit the rate for other float widths on geforce parts to segment the market.
You are exactly right you don't take a 25 year loan during a war to build a mall. You devalue your currency by firing up the money printer.

America’s Vaccination Rollout: Fragmented Communication, Misallocated Supply
> I've read a bunch on this, and haven't been able to find an authoritative source for what the efficiency conversion is -- how many acres of solar panels power how many acres of vegetables, and is it greater or less than 1:1? -- but it's certainly not as simplistic as "solar would need 3x more land because they are 30% efficient."

I own a townhome, so my only real ability to grow plants is through a grow-light connected to electricity.

As such, I've spent some time calculating the PAR values of a decent grow-light, as well as the amount of PAR that natural sunlight gives. Plants need a ludicrous amount of PAR (basically blue + red lights, green not needed cause green just bounces off of plants).

Sunlight is mostly broad spectrum: broader than plants need and therefore a source of inefficiency (green light is wasted) that LEDs can somewhat replace.

Grow-lights have a benefit that they can be placed very close to the plant (maybe just 1-foot away) to "focus" the energy a bit better. Nonetheless, the amount of PAR / PPFD from a typical day sun (or even a cloudy day) far exceeds what you'd get from 500W or even 2000W grow lights.

--------

Its just a hobby of mine, and I'm not growing anything especially hard (just Basil, which is really easy to grow... but Basil is a summer plant that really wants sunlight).

Still, once you start calculating PAR and actually mapping out how much electricity your "emulated sunlight" needs, you'll realize how grossly inefficient that "solar panel -> electricity -> LED" plan really is.

EDIT: Natural sun is like 2000 PPFD or something FAR in excess of what most plants need. Still, a good growlight solution might hit ~1000 PPFD constantly. Lets take this 650W LED and think about it: https://allgreenhydroponics.com/collections/american-made-le...

You'll get ~500 to ~1000 PPFD across a 4'x4' or 16-square foot area from that 650W LED (and most of that light is focused on the center: you'll want to overlap your lights a bit for more consistency).

Then think about how much solar panels you need to power a 650W LED for the 16-hours / day your typical plant would want (to account for the lesser PPFD indoor plants get, you run the lights for a bit longer than sunrise-sunset).

Just some napkin math. Nothing serious here: just guestimating the area in my head.

----------

EDIT: Now it should be noted: I've heard of good hydroponic greenhouses that have the "do both" approach: glass roofs to let the sun in most of the time, and LEDs to augment the natural sun (cloudy / rainy days, as well as winter-settings when you have fewer hours of sun). The sun isn't nearly as consistent as we'd like, but... that means that you need something aside from solar power powering those LEDs.

But the concept of building a all-LED underground (or "inside a building") without any natural light just... seems grossly inefficient to me. Such a setup only seems useful to those growing contraband IMO.
I flew to Austin back in 2013, spent a week looking at places and checking out hiking areas and running. I loved the food/friendly people but that was about all. For me it was a dealbreaker on lack of trails/wilderness, and also the very high humidity there. In addition housing was expensive as I looked at a few condos and they were roughly the same cost as the one I used to own in San Jose.

WA seems very nice, the no state tax thing basically means a free mortgage payment if you are making good money in tech(not paying CA taxes)
How to Digitize a Logo for Printing
Look through several nuclear locations and ~1000 acres is fairly typical. In theory they could be more compact, but security concerns etc means nobody puts 2GW of nuclear on a 200 acre site.

1,000 acres, https://en.wikipedia.org/wiki/Beaver_Valley_Nuclear_Power_St...

1,782-acre, https://en.wikipedia.org/wiki/Byron_Nuclear_Generating_Stati...

2,767 acres https://en.wikipedia.org/wiki/Callaway_Nuclear_Generating_St... for just 1,190 MW.

Some are significantly more compact for example 391-acre https://en.wikipedia.org/wiki/Catawba_Nuclear_Station, but that’s surrounded by water.
Because evacuations are not done on perfect hindsight. They are done with limited and often incorrect live information. When building are collapsing atop a reactor, when nobody knows for sure what is happening inside, it is only reasonable to start moving people away.
I think the broader point as to why that comparison doesn't work is in situations where its trying to communicate the point "I can't do this, so the government can't do it."

In this situation, its "I'm able to do this, so why not the government?"

You're saying that a couple of 50 year old reactors when including a safety zone and adjusting for lifetime capacity outputs about twice the maximum power of commercial solar panels before adjusting for capacity factor.

When you adjust PV for capacity factor the difference ends up at over an order of magnitude.

I'm really getting sick of seeing all of this rhetoric from people on HN, reddit, etc. that seems to want to dance on the graves of a bunch of people in Texas who have literally frozen to death.

It is especially ridiculous considering that many of these people doing the dancing are from California, and many of them have fled that state towards Texas, a place they now are demanding implement California-like policies. It would be funny if it wasn't so sad.

California has massive wildfires, rolling blackouts, and deaths as a result of these things every single year and has for the last decade. It happens, like clockwork, every single summer. And yet every single year the state throws its hands in the air, blames the federal government, and waits until next year.

Texas is facing a once-in-a-century black swan event[1]. If Texas got a storm like this every February for a decade, and continued doing nothing about it, then sure, maybe they could start looking to others (although literally anyone except the Californians) for help.

Until then I hope that everybody either proverbially picks up a shovel, or closes their mouth and gets out of the way. There are people suffering. Stop trying to extract joy from it.

[1]No. The storm that Texas saw in 2011 is not comparable to this. Yes, there were recommendations made on how to mitigate catastrophic temperatures like Texas is seeing. There are also mitigation strategies for things like: war, flooding, meteor strikes, hacks, earthquakes, and other "acts of god". It is simply not feasible to put ALL of these recommendations into practice.

I was scratching my head too. It's also a broad statement to cover who knows what but I read "ground faults" while getting our tinker on. Agree the frequency and voltage would drop out of phase tolerance. That shouldnt cause fires unless there's a spinning resource that fails. The sudden availability or lack of power would create imbalances across the grid, frankly I don't think they know what would break. Might also drop one circuit and accidentally overload another, there's lots of failure points so they just broad stroke it.

The other component is decoupling health care and dental insurance from employment. Because that's a far bigger problem than retirement. A lot of people lost their jobs last year and suddenly had to pay full price on their insurance to keep going to their doctor.

The whole insurance system in the US is best described as a real-life re-enactment of The Trial by Franz Kafka.
Or it implies skilled people who would have had under the table side gigs are getting gig economy jobs because it's so easy and turnkey even if the pay is lower.

But you're ignoring the inefficiency of building separate hydroponic operations on individual rooftops and driving around to all of them, etc. Also as SamBam mention above, you don't have to make a simulated sun. Instead it can work as sun -> electricity -> narrow-spectrum-light-that-plants-convert-at-higher-efficiency. You might even genetically modify plants to be more productive with the smallest spectrum possible.

>I'm out in the countryside and I pay 20EUR per month for unlimited download LTE

You're simply not the target market. I live in the American countryside, where cell service of any kind is a distant memory several miles before I make it to my driveway. I pay $900/month to rent a second house in town because I'm fully remote but my current slow GEO satellite internet at home isn't suitable for remote work. $100/month for broadband internet is a phenomenal deal for me.
You could also do an alternate weighting, where you decrease the value of earlier votes before more projects were added.

Why would the device need to be any more complicated than a bluetooth speaker and microphone driven by a Raspberry Pi or something? That effectively reduces all the engineering necessary to making a case for the Pi that looks like a red rotary or push button phone, and stuffing a speaker and mic into the handset.
It’s a bit more complicated than this. A lot of big generators are induction generators, and the associated electronics can make a tradeoff of voltage and frequency. In a grid setting, the frequency will be maintained at 60 Hz plus or minus not very much. Everything is, hopefully, arranged to maintain the correct voltage and frequency. The actual mechanism behind this have always struck me as arcane and somewhat fragile, especially in light of modern loads that don’t act at all like resistors under varying voltage conditions.

Sitting in any closed space like that one, with other people, masks or no, is stressful right now. It's a shame that NASA can communicate with a rover 125 million KM away but their staff have to all be crammed into one small enclosed space. You'd think we'd be able to communicate just as effectively over several kilometers.

I imagine that people will look back on videos from this time period where ~3M people died (mostly unnecessarily) and wonder what on Earth people were thinking, carrying on like that.

That's why "real" space cameras usually have color filters on a carousel before the sensor - they take 3 pictures each with different filter and BAM, color!

That way you get high regulation as well as color. You can also have some special (infrared, ultraviolet, etc.) Filters on the carousel, not just RGB.
It's placing something that quite literally simply does not exist on the balance sheet.

A physicist who died 55 years ago said it'd be commercially deployed by 1975. 1954 was the "too cheap to meter" claim by an investment banker who worked for the Truman administration. That's still quoted today, said 2 years before Elvis debuted on Ed Sullivan.

We're all supposed to treat it like it's a valid opinion. While instead, 46 years after the predicted free energy for all bonanza, rate payers are getting hit with taxes to keep nuclear going. It's in practice, in actual reality, a more expensive option.

Continue to research. March on with science, sure. But as a matter of public policy and planning, relying on it is pure fantasy.

I don't know why hn is so koolaid-drunk on this stuff. It's a cult with 70 years of failed predictions. It's apparently like any other cult where wrong predictions make the true believers even more fanatical.

There is a big difference between installed capacity and how much is expected for a period of time. For instance, it is not 100% failure that a solar cell outputs no power overnight; that's just the way they work.

There is plenty of wind generation going on in Canada or Sweden; one presumes the "make a wind generation system work in the cold" is a solved engineering task. Those windmills are a little more expensive.

Is this a result of poor planning or is this novel failure? This smells like a failure driven entirely by inappropriate cost optimization.

Most of them didn't - our life expectancy in Texas today is miles above what it was in the mid 1800s and that's even without bringing in any self-selection of migration. Only the folks that thought they were particularly resilient would move to the frontier to begin with - someone with anemia probably isn't going to be traveling west and homesteading.
