p-values that are not in the physics ranges are ridiculous.

It's a shame everyone started copying physics but decided for higher acceptance/rejection values.

I was a little bit disappointed when I realized that a bunch of valid modern science is just proper experiment design and number crunching. If it's not physics, there's no models of why things work, there's just a p-value on the correlation or some other comparison function.

Medicine has turned into a field where you can't know a thing.

I love reading reports like the above:

> There is currently no evidence that supports or refutes that these interventions(chiropractic intervention) provide a clinically meaningful difference for pain or disability in people with [lower back pain] when compared to other interventions.

p-values really do not help that much.

What is not the case? 1-2% of total CO2 footprint? That flying a full plane is equivalent to months if not a year of driving a nontrivial distance every day?

I'm not saying cars are more efficient. It's just that the distance travelled is huge when one uses an airplane.

Depends on how many. Flying airplanes is around 1-2% of our total CO2 footprint. Of course, for an individual, doing 1 intercontinental flight with a full plane is equivalent to months if not a year of driving a car to work every day, but in total, not many people fly.

Depending on the efficiency of the rocket and the reduced number of people doing this, the numbers shouldn't be that much higher.

But there's only 3-4 DOM elements. I'm pretty sure doing this in canvas is not as trivial as this.

Given there's only a single svg element changing I'm not exactly sure you could have done it better.

It might just be that the ease-out transitions for the stroke are not efficiently implemented in whatever browser you're using.

If you've tried and check out and understand the code you'd see there's so little being done in JS that this stuff is surely not the bottleneck.

Holocaust is a word that has its origin long before The Holocaust happened. [0]

I did not call the non-human animal holocaust as The Holocaust (committed by the nazis).

Here's a Jewish Holocaust survivor https://www.reddit.com/r/IAmA/comments/2h8df0/i_am_an_80year... that gladly uses the word holocaust to talk about what is happening to docile, domesticated animals all over the world.

Here's a notable survivor too https://en.wikipedia.org/wiki/Isaac_Bashevis_Singer#Vegetari...

I'm pretty sure SpaceX hired the old experts that are stuck in the past.

There's nothing stopping you from iterating after the experts gave you a perfect start.

About a billion cows or so annually.

Cage free is still factory farming, there's just no cages, but a huge big closed dark cage. I'm in no denial when I'm buying those eggs.

The thing is, people don't really care about animals. Especially not the kind, calm and docile ones.

A holocaust is happening currently, 60 billion most docile and mostly female cows and fowls are eliminated every year. No one gives a damn.

Heck, even I don't. I drink my milk and eat my chicken. I consider those things mine and don't care if the milk is a product of forced selection that created a monster of a species, or that chicken is a flesh of an innocent animal.

I do not even care about what it does to the environment.

I'm voting with my money to have this practice continue.

The whole system is built for meat and milk to work. Yeah, it's some wierd suboptimal local minimum but that's what it is. I live in a meat culture and don't care if I can survive eating only plants.

I'm confused that Tesla did not hire these experts. I see Munro & Associates dropping criticism, and am baffled, given so much expert knowledge available that no one hired these guys or their competition.

I think C++ compiles down to a pure functional language that is then optimized into an efficient beast. So I'm not sure that pure code is hard to optimize.

The rest of my comment explains that worrying about BTC CO2 impact is useless.

People do a bunch of stuff that has magnitudes bigger CO2 footprint.

Are we profiling CO2 usage? If so, what, we want to optimize the tiny footprints instead of the biggest?

BTC mining, just like Christmas lights, can work with solar. Then we are going to complain about electricity wasted.

I'm not sure. Given that he was in a relationship with a professor there, he might have got an easy pass.

Ton of CO2 is generated by christmas lights. It trumps BTC or is very close.

Yes, producing a lot of cheap energy is an opportunity to use more of it.

There's a bunch of stupid things people do with energy and increase their CO2 impact. Bitcoin is just one.

I'm pretty sure abstaining from flying planes throughout all your life is more CO2 not emitted than building a small mining operation and mining for life.

I'm pretty sure if we summed up the CO2 impact of increased dietary requirements of athletes and body builders and similar would get to huge numbers.

Weird, no Animal Liberation by Peter Singer, one of the best applications of utilitarianism.

When profiling are we optimizing the fastest functions?

Heating and cooling trumps the transport sector with 30%+. Globally, stuff does skew a lot from our first worldly habits.

If you do the calculations similar to those done in http://withouthotair.com/ you'd see your first worldly habits put your heating and cooling at the top, and probably your diet at the second place.

The CO2 impact of your car driving is much less than impact from heating-cooling, and probably also from your diet. Cars are efficient machines. Houses are rarely built well, especially in the US, and the production of common US diet ingredients is ridiculously inefficient but heavily subsidized.

There is deactivate and delete option for years now.

Zuckerberg stated that they delete all of the data after user deletes their account (not deactivate).

Thing is, I do less than 1 lesson per day. Probably 3 lessons per two weeks. Meaning that I press Practice button about 100 times in that two week period.

After about 40 days, I went back to go through some of the previous lessons, given their new Crown update, and realized I haven't seen some of the words at all.

Despite having around 400 words learned so far.

I still find their spaced repetition lacking. I never see some of the words again after seeing them for the first time.

I'm pretty sure taxing by calorie density would make things better. There's no cost in doing that, it would just shift people to eat less calorie dense food like fruits, vegetables and leafy greens.

The main problem is that the current laws, taxes and infrastructure are heavily optimized to produce calorie dense foods. Another is that people like some of those foods on a regular basis in their diet, so they might complain.

I would say this would cost more in political points than in real money.

For a country that is so weighed down by the health issues around obesity, it's quite weird taxes/incentives based on calorie per gram isn't anywhere in sight. The savings from not having to take care of so much sick people would be enormous.

It's clear from the situation that the free market choices are suboptimal. Who wants to suffer through most of their life and die early? Yet these choices are still made. If you can't educate, then tax fairly and force them to make the right choices.

You can use the same trick to make your models sparse. Less parameters means less flexibility to interpret output "correctly".

It is a common mistake to characterize communism as collectivist. Marxist notion of communism is brutally individualistic.

Antibiotics for human use are nothing. There's around 70 billion domesticated land animals being born and dying every year. That's 700 billion Petri dishes with varying antibiotic power in just 10 years, and that number is more than all of the humans that ever lived on Earth. More than enough for some massively superior bacteria to evolve.

Well, spinach E Coli is there because we use cattle poop all over it. Nothing better than fertilising our vegetables with manure rich in antibiotics resistant E Coli.

Are discoveries about black holes legit?

Isn't it still the case that they have not been experimentally confirmed to exist, and all talk of discoveries is just conceptual?

If only we didn't waste all of the antibiotics on non-human animals. Such a bad use of brilliant biotechnology.
