You need to comprehend the complete loss of trust in authority. This has gone so far as to be inverted: if the government, academia, media, etc enthusiastically endorse something then it is assumed to be harmful until proven otherwise.
I say this as someone who shares this mindset. It is as shocking to me that you would queue up for a dangerous vaccine, support mass 3rd world immigration, consume slop full of soy and seed oils, etc as it no doubt is to you that I would be an openly racist anti-vaxer who gets his steaks and eggs straight from the farm (and would my milk too, if it wasn't illegal here).
It doesn't help at all that the champion of pasteurization was one Lord Rothschild, whose only two addresses to UK parliament were for Zionism and the prohibition of raw milk. If one is considered a program of genocidal supremacist hatred of my people, it's a very tough sell that the other is supposed to help keep me safe and healthy.
A healthy scepticism for gov and media seems good to me but inverting what they’re saying seems less than sound. At that point what’s left as a sound basis? Fringe blogs? Facebook lunatics?
Do your own research isn’t viable either given that I can’t be an expert in everything. Especially with the rise of misinformation. At some point you’ve got to trust something
Steak and eggs from the farm seems quite reasonable to me. ;)
“Do your own research” would be ok if people actually did research. Or at the very least, if they were just reading other research they’d look at primary sources and considering how innumerate most people are, made the effort to learn statistics before.
“Do your own research” is absolutely ridiculous when what it means is diving deeper into the rabbit holes presented by the YouTube or TikTok algorithms.
Where are all the mass deaths and murders since then?
Even overall death rates and mortality rates have fallen across the world after jumping up during COVID itself.
Even an extremely tiny risk of say 0.1% should have seen aroun 4 million dead. Where are all the overflowing morgues and need for new hospitals we saw when COVID, which has a low mortality rate, and had definitely not infected even close to 70% of people in Italy, or China, was spreading in the early months?
If you think that will increase their appeal then you don't truly understand why diamonds are valuable. It's what they represent.
The princess doesn't want a gem on her finger that has been cultivated by a nerd and comes with a "vegan, soy-based, cruelty free" approval on it. She wants a warlord to return from conquering and pillaging foreign lands, leaving rivers of blood in his wake, to deliver the prize to his queen as a symbol of her value and his material investment and dedication to her.
Obviously no woman in her right mind is consciously thinking that, but that's the psychology behind it. "Bloodless" is icky.
That's like your nan being frustrated that there isn't a single definitive guide to buying a laptop.
There are so many factors that it's a near-impossible task. And even if you somehow managed to do so, it would already be obsolete by the time you stopped typing.
The datasheet (for each of the ESPxx, regulator, etc) will specify power consumption in different states. But sadly there's a lot of misleading amateurish pseudoscience in Arduino-land so you're best to ignore everything else (which would even include a guide like this, for example).
I think there's some misunderstanding on the expectations. Documenting a combination of all the available peripherals, boards and power sources is virtually impossible but that is not what I meant.
Given a power source and board with defined power requirements (e.g. say 3.3v upto 150mA) if we can easily find what commonly available components are needed and how to wire them up (with tradeoffs) is sufficient.
PS: If you find the video format of tutorials useful for learning about electronics, Andreas Spiess and Great scott channels on youtube have very good content that is helpful for beginners.
If you're this new to electronics though, you're better off buying a hobbyist development board like any of those suggested in the guide. You don't need to concern yourself with this. Just plug in the USB cable.
If you're designing your own board, you would simply enter 3.3v and >150mA into the parametric search on Mouser, Digi-Key, TI, etc and pick whatever part takes your fancy.
This is so simple that there isn't any need for a guide. The datasheet for whatever regulator you choose will tell you the recommended input capacitance, output capacitance, inductance, any configuration resistors, etc.
Same goes for battery charger ICs, which can be just as simple or far more advanced, and there are new devices being announced all the time for everything from tiny energy harvesting applications to USB PD, which is what I mean when I say it'll be obsolete by the time it's announced.
It's daunting at first but you need to take the plunge: find a part that interests you on Mouser, integrate it into a design according to its datasheet, and order some PCBs. You'll be amazed how accessible it is.
How to read that info from the sheet? Problem: I have my NodeMCU gizmo with sensors and stuff, that works while powered via USB charger. I want to make it portable and powered by AAA batteries. How do I do it? I feel that my nan would've had an easier time figuring out on her own what laptop to buy.
That's not what it's designed for. That's like asking how to run your iPhone on AAAs.
The hobbyist solution would be to find some obscure product on AliExpress with a holder for 2xAAAs and a 5V boost regulator with a USB connector. It's janky and inefficient, but that'll power your board, or your iPhone.
The 'proper' solution would be to then take this prototype to an optimised design in your ECAD software of choice, integrating a AAA holder and choosing an appropriate regulator, and having some PCBs assembled.
I'm not sure what else you could want. If the latter sounds daunting to you, it would be very easy for even an inexperienced EE on Fiverr to whip up for you.
Same thought. It’s a bit of a bait and switch as the title implied to me a major milestone. But it’s not and the real milestone of renewables providing power continuously day and night remains.
“a specially designed photovoltaic cell could generate up to 50 watts of power per square meter under ideal conditions at night, about a quarter of what a conventional solar panel can generate in daytime”
The idea is to capture the energy that escapes into space when solar panels cool down during the night.
So batteries are too expensive, but space launches aren't? Even assuming the light can be sufficiently focused to bypass the inverse-square law, it'll still need precision manufacturing to actually deliver the power to the panels reliably. And that's assuming mirrors are enough, and you don't need space-side solar panels and microwave/laser beams (which will be even more expensive than hundred-mile-focus mirrors).
Push am (ever so slightly) larger fraction of the sun's energy output into our atmosphere, what could possibly go wrong!
I know, the amount of net electricity per added total energy might end up no worse than in a fusion power best case scenario, but still... When you add the climate effect of re rocket launches required I don't think it could ever become worthwhile.
So they could build a battery big enough to serve 15 minutes of the nighttime trough and declare mission accomplished with only enough solar to fill the battery on a rainy winter solstice day? Some goalposts just beg for getting moved. (I assume that this is unrelated to the 2045 goal, so it's not really bad, just bad headlining)
Is it not obvious that scarcity provides the harsh and unforgiving conditions for the natural selection of positive traits?
Taking Europe, for example, our ancestors would not have survived without their adaptation to the climate and its consequences, breeding cooperation, empathy, industry, invention, efficiency, etc. A frivolous, impulsive, unintelligent people seeking immediate gratification would not have survived the winter.
What I mean is, it's not clear that those traits are sufficiently genetic in basis for natural selection to occur. There may be more of a cultural incentive to encourage those traits.
Of course there's a strong genetic component. For an extreme demonstration, no amount of cultural pressure is going to prompt the emergence of these attributes in a population of watermelons or earthworms.
I agree that you need to code for some level of intelligence in the first place. But I think you need to go further and show that there is genetically-driven variation in those traits among humans. Otherwise it may be that the variation is due to socialisation or epigenetic factors.
Beat me to it. I was going to point out that there's a ye olde black and white photo in my town's information centre of that one time we had snow here!
Boring short article that names three Tinder founders and adds no other founder details other than two claim to attend their parents’ Shabbat dinner tables every Friday.
>You see people on Tinder dates sitting at a restaurant table each still scrolling
Do you actually? That's appalling.
Some time ago I was on a second date with someone (met through a friend, not Tinder) whose phone was frequently pinging the Tinder notification sound. She was very pretty, I was under no illusions about the level of competition, but I was so insulted by the disrespect. Imagine not even putting your phone on silent! Had no idea it could've been worse, god help me if she got it out and started swiping.
I say this as someone who shares this mindset. It is as shocking to me that you would queue up for a dangerous vaccine, support mass 3rd world immigration, consume slop full of soy and seed oils, etc as it no doubt is to you that I would be an openly racist anti-vaxer who gets his steaks and eggs straight from the farm (and would my milk too, if it wasn't illegal here).
It doesn't help at all that the champion of pasteurization was one Lord Rothschild, whose only two addresses to UK parliament were for Zionism and the prohibition of raw milk. If one is considered a program of genocidal supremacist hatred of my people, it's a very tough sell that the other is supposed to help keep me safe and healthy.
