Moving all private cars to electricity will increase total electricity consumption by 19% (https://phys.org/news/2015-07-cars-electric.html). This number is not something worrying in any way, and well manageable by the current incremental improvement of the electricity grid.
I think the vast majority of this is due to high home and rental prices. I really think we need to fix this, especially when demographics are trending towards less people.
Here's my quick intro to hydroponics.

If you want bridge your grow with automation and coding I recommend everyone take a look at

https://github.com/kizniche/Mycodo

If you're looking for instrumentation/controllers for your grow (CO2, PH, TDS, EC) I recommend:

https://atlas-scientific.com/

If you're indoor and need lighting, build your own LED based lighting. Use the Samsung LM301B or LM301H led. I shopped https://atreumlighting.com/ for my last DIY kit and my light fixture came out perfect.

If you're buying nutrients or supplements, always try to get them in powered formula. Liquid based formulas are typically more expensive because you're paying to ship the water around and water is heavy. Most nutrient lines provide a feed schedule and dosing. When doing nutrients, less is more, never give your plants too much fertilizer, you will damage your grow and burn your plants.

Yes, I'm growing cannabis, you can see some of the fun we've had over the years at:

Because bourbon takes (something like) ten years to "age" if you want to start a bourbon distillery you either have money to run ten years with no product, or you white label something else for ten years until you get your own going.

So many industries are like this, just out of sight of the average customer, it's hilarious.
To expand on that:

Comcast would much rather sell a dedicated fiber to a business with capital and guarantees.

Selling to the individual consumer doesn't make a lot of sense business-wise, because of the deployment costs and continued support costs.

Comcast is also abusing their status as oligopoly to gouge costumers financially and qos-wise, but if they're selling to a business that buys large quantities and has staff who's job it is to handle network problems, they actually like that (right up until that business threatens to compete with them in areas where said oligopoly is in place, of course)
Yeah, I'm thinking that such people, if they exist at all, are heavily outnumbered by the people saying

* Not actually physically possible

* Its just coal powered

* It's worse for the environment because batteries die after 3 years

* Rare earths!!

* Subsidized foolishness

* Toys for rich people

* Communism

And weirdly those people all get paid to write op-eds in right wing tabloids.
My father has worked in the meat industry his entire life and said that over the decades, he was shocked how unnaturally cheap meat has become.

I'm in no way anti-meat, but a lot of people have normalized eating a huge amount of meat per day at ultra low cost, and internalized this as some basic right. Natural consumption of meat is to eat meat sporadically, not 3 times per day.

I'm not questioning whether one likes meat, I do too. I'm saying you don't need it in these amounts nor should you expect it to be this cheap forever.
Uncanny timing, I literally just bought a Numatic George yesterday!
Wikipedia's discussion seems pretty good. Fundamentally, force calculations in classical physics tend to be replaced by perturbation calculations in quantum mechanics.

https://en.wikipedia.org/wiki/Coupling_constant

> "A coupling plays an important role in dynamics. For example, one often sets up hierarchies of approximation based on the importance of various coupling constants. In the motion of a large lump of magnetized iron, the magnetic forces may be more important than the gravitational forces because of the relative magnitudes of the coupling constants. However, in classical mechanics, one usually makes these decisions directly by comparing forces. Another important example of the central role played by coupling constants is that they are the expansion parameters for first-principle calculations based on perturbation theory, which is the main method of calculation in many branches of physics."

Perturbation theory and calculations depend heavily on the coupling constant. If I recall correctly, in quantum electrodynamics (Feynman diagrams) the coupling constant is ~ 1/137. If you raise this number to higher powers (adding terms in the pertubation process) it quickly falls off towards zero, so you can get very accurate calculations using this approach in QED.

https://en.wikipedia.org/wiki/Perturbation_theory

With the strong force, this coupling constant is much larger and so the higher powers in the perturbative calculation are significant, meaning it's much harder to calculate accurately with QCD compared to QED. From the paper, this reference:

* Improving our knowledge of αS is crucial, among other things, to reduce
the theoretical “parametric” uncertainties in the calculations of all perturbative QCD (pQCD) processes whose cross sections or decay rates depend on powers of αS , as is the case for virtually all those measured at the LHC. *

It does not unless that money is spent competing with businesses and citizens for resources. However, in this case the money had already been earmarked for rural internet service and is not being used to purchase goods and services that citizens would be buying instead.
Yes, inflation is currently a world-wide issue, and explanations at the world level lead somewhat obviously to the pandemic and Russia's invasion of the Ukraine.

But here in the USA, people like to believe it must be political and local, completely unrelated to the totally-coincidental worldwide issue that happens to be very similar.

A Renault Twingo weighs about 2150 lbs. This is a sensible car which seats two comfortably and four in a pinch. It also gets 40-50 mpg. No, you can't transport your quad with it, and it's not very useful when moving house. It's also not the right car if you're currently raising three kids; most aren't. The average occupancy rate for cars is 1.5.

Car taxation should scale quadratic with weight.
I'm saying to allocate budget to maximize as much as possible the public/global interest.

Yes it's nicer to have optic fiber, but this is somewhat luxury if Starlink exists, and if the gov funds it already.

I'm sure some other people in the US need more these 30'000 USD than optic fiber to watch Netflix with a little less buffering.

Budget could be used somewhere else (to build roads, or to support medicine/health, education, animal welfare, etc).

So it's not about refusing to help rural / remote people, but rather about optimising allocation in order to support as much people as possible.
There are FPGA dev kits that are fairly affordable. It's probably still cheaper to get a breadboard and a bag of 54xx chips if you want to learn digital logic but I'd say the problem for hobby FPGAs is that the developer tools are poor and the FPGA vendors keep the bitstream format secret so there is no competition to produce better developer's tools.

I was also going to mention some dev boards NVIDIA had come out in the last few years that were affordable (I think) but they are all out of stock now and the ones you can get are $2000+ now.
5G base stations have a range on the order of 1000 feet, and need to be connected to a high-speed backbone to function.

In rural areas, a 1000 foot radius doesn't get you very many people, and since you ran fiber all the way to that antenna, you might as well run fiber the rest of the way.
Well, in this case they're not just inventing nonsense to fix one little thing. There are a lot of various pieces of evidence, all pointing to this fix. If you want to patch up a lot of little pieces of evidence, each with it's own magic, that would be even more "un-parsimonious".

The evidence for dark matter is pretty solid.

As this [1] article states, while giving 5 independent reasons scientists think dark matter exists, "No other idea explains even two of these".

Wikipedia lists eleven different places it shows up.

The research literature has more. And AFAIK there is no other unified (or even close to unified) explanation for all these observational pieces of evidence.

Workers can't afford to pay the rent being asked though? If you're paying such insanely high prices for land, you need to get a pretty high return on the land to fund the next purchase ? In that regard it seems like a race to the bottom?

Also, remote work is now becoming more of a thing than ever, so people have much less of a need to live in Sydney itself and pay crazy high rent. I can see this happening in many other major cities.

I actually left a major city recently where I was paying 5x the rent I was paying pre-pandemic. Things just aren't what they used to be in this regard. I also now have way more money to save and invest in property myself, or other things such as shares. I feel like before I was a slave, now I'm somewhat liberated.
It's increasingly difficult these days to write scrapers that don't at some point need to execute JavaScript on a page - so you need to have a good browser automation tool on hand.

I'm really impressed by Playwright. It feels like it has learned all of the lessons from systems like Selenium that came before it - it's very well designed and easy to apply to problems.

I wrote my own CLI scraping tool on top of Playwright a few months ago, which has been a fun way to explore Playwright's capabilities: https://simonwillison.net/2022/Mar/14/scraping-web-pages-sho...
I remember being one of the first units to get google fiber in Provo, UT back in 2014. Up until that point there was other fiber providers but they had no competition. Once google fiber came in suddenly Comcast tripled their offering speeds for no additional cost, and units and homes that had google fiber were more desirable.
If you can put USD 50-100 in your antics, you may add an XT-IDE ISA card with a Compact Flash adapter.

The one I have has a slot in the backside metal bracket: I can load a Compact Flash (1 GiB, FAT-32 formatted) in a modern PC with a USB adapter, then I insert the Compact Flash in the back of my IBM PC and switch it on with new fresh data and software.

Note that the Compact Flash is seen by DOS (6.2 in my case) as a hard disk drive, you may boot on it. It may also co-exist with an MFM harddrive: in my case, the MFM drive is C: and boots, the Compact Flash is D:.

It is a very convenient setup to make the IBM PC a smooth place in our modern IT world.

What's the expensive part of a new fibre run? With $30k you could hire an excavator and operator for maybe 15 to 20 weeks straight, but I'm guessing the pits are expensive and dealing with obstacles is hard.
words no longer mean things.

We’re living in a world where nearly everything is low quality. It’s the old Sam Vimes narrative about being poor being expensive, but it is currently challenging for people of any means to find a quality product without loads of research and expertise.

And even then, it’s subject to change as good brands get bought by someone larger or new management comes in and cuts quality to increase margins.
Don't be ridiculous.

The Fed has aggressively raised interest rates and signals that it will continue to do so, and there is widespread worry about a recession. We've had two quarters of negative GDP growth! (though I tend to think the numbers will revised upward eventually).

Thank you for this. Seriously, it had to be said.
There's also the concept of "speech is violence". The parent comment makes the assertion that there is a difference between hate speech and speech that incites violence.

While the line seems very clear, the issue becomes when you start redefining what "violence" is, or start extrapolating. Say you go out and make a disparaging comment about a protected class, the comment is disparaging but it does not directly call for violence.

An argument will be made my some that even though your comment does not cause violence, a crazy person will hear your comment and then proceed to commit violence based off of that. You can extrapolate that to almost anything.

I can say "I think Javascript is a terrible programming language". Some crazy will take that to mean: "JS is terrible, therefore all JS devs are terrible, therefore I need to go out and commit violence against JS devs". The argument could be made here that the comment "I think javascript is a terrible programming language" is actually a call to violence because someone interpreted it that way.

Google is too be solely blamed for it.
Pretty much all android users prefer Whatsapp, Line, Wechat etc compared to traditional SMS. They could have had one proper chat application rather than having 10 of them in this decade alone. They are doing the same thing right now with Google Meet/Duo.

While iOS users prefer imessage, SMS, over other messaging services like Whatsapp.
The problem here IMO is that although intelligence can be fairly well defined and measured and it tends to be fairly static over a given period of time, happiness can be more difficult to measure or define and fluctuates.

Someone may say they are less happy on Monday Morning than on Friday afternoon, or they were happier last year but then the pandemic lock down saddened them. And, some people perceive their own happiness differently, on person may say, I am very happy, but they perhaps are not as happy as another person who says they are only moderately happy because they may have a higher expectation of happiness.

And what is it really, many philosophers have spent a lot of time on that topic. Is it that all my needs and wants are met and I am in a committed relationship? Others may define it differently. The article touches on these points.

In my view these are just two different unconnected attributes, asking if intellect and happiness are correlated is like asking "how big is the color red?" it is not really a meaningful question.

Anyone can be happy, whether they have a high IQ or not.

Say you have one man who has a low IQ, works as a laborer, but comes home to a wife and loving children. They do not have a large house or fancy car but if you ask him, he may say he is very happy.

Another man, lives alone in a large home with a nice car but enjoys solitude and contemplation, perhaps occasionally having a friend over and they have a deep conversation about quantum mechanics. You ask him and he might say he is very happy.

Obviously, you could easily reverse those examples and add many more.

Now let's measure that?

Personally, I just don't see how.
Ah but "Big Data" attracts the people who took a course on Spark and now see it as the tool to apply everywhere. It's turtles all the way down ;)

When I'm hiring I've settled on sticking with "Software Engineer" and gasp being as specific as possible on what I'm looking for. But nothing will ever be perfect, or even great.
They were broken out into a subsidiary in 2015, which means their management will be seeing pressure to show growth. I’d imagine they’ve probably hit about as much as they can hope for on their existing markets and are especially looking at the number of people now working remotely for the long-term.
There are other reasons: the boiler is from the 1940s (59% efficiency) and the oil tank is at least 30 years old.

"In Sydney, houses are so expensive my whole generation will be practically forced to rent for life"

Something i've been thinking about for a while. Gen Z and Millenials are not having children at replenishment. The older folks are living a lot longer, so our population is still going up today, but the 30 year olds who will have children are alive today, we can count them. There's less of them. As older generations start to dwindle, and are forced to move to long term care situations (which to be fair, I think a lot of boomers will resist as hard as possible), the housing supply crunch will probably go down. The real drain on society will be a raising retired population, and a dwindling working population. The older generations outnumbering the younger isn't going to help the younger generations politically either.
The programmatic transitions between still images use linear RGB space, which is the correct way to interpolate between two colours. The maths behind it is pretty simple - essentially just reversing the gamma correction from normal (0-255) sRGB space before the interpolation and redoing it for the final colour (no need to get into the hairy areas of LAB or perceptual colour spaces for this). Once we know the colour we want, we choose the character (from a list of 6) and attribute which most closely matches that colour. Of course, it's all done using lots of lookup tables so that we can process several hundred character cells per frame.

Further, they should be forcibly blocked from using any services they refused to pay taxes for. No highways, flood protection, low food prices, or access to the global trade network for you!
The problem is not what people read, but what they do not read - journalists have an axe to grind against Facebook, so they write titles that make it sound like Facebook willingly gave the data to the police, and most people don't go beyond reading the title.
And this is such a good example of why single-person review sites are not the answer to the problem. The site is in theory most useful to people who don't know much about the topic. But to know that the site isn't credible, you need to know a fair bit.

One solution is things like Consumer Reports and Wirecutter, where you have an institution that does some quality control. But I wonder if there's something in the middle, like a few good reviewers clubbing together and certifying one another, such that there's a recognizable brand that they share, one with meaningfully high standards.

Oh, that's interesting. I wonder how they get past regulation in countries like Germany as you said. I'd assume they'd have to be registered as an official operator there?

Quick plug for running scrapers in GitHub Actions and writing the results back to a repository - which gives you a free way to track changes to a scraped resource over time. I call this "Git scraping" - I've written a whole bunch of notes about this technique here: https://simonwillison.net/series/git-scraping/

Also a fan. Usually I generate indexes/urls, and then just wget and scrape the content offline once all is downloaded.
I get the idea, but this is basically just admitting that our representative form of government doesn't work. Ostensibly we control our taxes already by who we vote for.
Somewhat related, what do people think of Crystal (a compiled language with types with Ruby-like syntax)? How is it for web applications? Is there a Rails equivalent for it yet?
You should read reports by actual experts instead of media.

The RUSI - Royal United Services Institute - is a leading UK military institute that had boots on the ground assessing the situation. Here is their assessment. https://rusi.org/explore-our-research/publications/special-r...

"At present, however, several Russian advantages and Ukrainian weaknesses are leading to an attritional conflict that risks a protracted war, eventually favouring Russia."

And here's the companion podcast
https://podcasts.apple.com/gb/podcast/a-turning-point-in-ukr...

It will tell you a lot of things, including that Ukraine's losses are far higher than the general public estimates, as Ukraine successfully hid/minimized the awareness of its losses from phase 1 of the war.

I also recommend the War on the Rocks podcast with Michael Kofman, whose assessment of the situation is also not too rosy.

I am extremely pro ukraine. But that's the reality. At the moment Russia is winning and Ukraine is losing, just very slowly.
The US aren't at war with Russia.

Sure, they're helping an ally in a De facto war against Russia, but currently the us spends more on "defense" than both Russia and China combined, when it is technically at peace. In case of a war with China, are you expecting the military budget to not increase at all?
I believe the OP means what went wrong for consumers.
Yep, it’s not going to work for everyone immediately. But it will for the majority, and over time, it will for everyone. As they become more common, the culture will shift and make this resistance seem more and more obviously ridiculous.
The resources of this country are to be allocated for the benefit of its citizens.

In other words, it is our money, and we can spend it on decent internet for rural areas.

If you need to stick with Python, Joblib is more reliable and works better than Multiprocessing in my experience.

I ran into so many subtle quirks that needed workarounds in Multiprocessing. Joblib.parallel with the Loky backend just seems to be Multiprocessing done right.
