scantis··on If everyone were vegan, only a quarter of current farmland would be needed
I was supplying nuance and another perspective.

Sorry but eating chips, french fries and drinking energy drinks won't save the planet.

scantis··on If everyone were vegan, only a quarter of current farmland would be needed
We easily feed them and move a year supply of food around the world just mess with the prices. Also we throw away about 70% of human food.

Canibalism can cause severe deseases, if the protein isn't prepared correctly, but for craps it seems the way to go to find stability with any habitat.

It is my personal opinion to strive for a future with more variety in food and more opportunities.

Instead of being vegan and eat a block of starch each day.

scantis··on If everyone were vegan, only a quarter of current farmland would be needed
You are absolutely right.

With sustainable methods, we would have to severely cut down meat consumption or depopulate.

I wouldn't say I propose a solution, but there is a middle ground and quality is very important.

If you think about it, photosynthesis is about 4-6% effective while high end solar cells are about 20%. LEDs give you a yield of up to 60%. So we could look at a future, where farmland is not required.

Seems strange, but growing plants below a city could be even more sustainable then on farmland.

Making everyone go vegan definitely isn't.

scantis··on If everyone were vegan, only a quarter of current farmland would be needed
There are tons of justifications

nutritional value availability it being delicious tradition and heritage sustainability

and so many more

Even you whole food vegan types have a final form as a hunter.

It is the logical conclusion if you care about the environment and animals, want low CO2 emissions and stay away from high intensity farming.

scantis··on If everyone were vegan, only a quarter of current farmland would be needed
This calculation is fatally flawed. Meat processors are extremely efficient in producing calories from unusable material in any environment. For example a reindeer eats basically moss, wild mushrooms and gras and can grow to 60 to 80 kg in a year. They can occupy unfarmable land.

Goats can be easily raised in mild desert, where there is no way to efficiently farm anything else.

There other even more efficient protein processors, like fish, who don't even require farmable land.

There are various types of wild chicken that can be held a forrests. They eat various insects and are much more tasty because of it.

Most high end pigs are exclusively fed by acorn and the like to aquire an astonishing well defined taste. You can not eat acorns directly, and even if you process them into oblivion, they can not compete with bacon.

We waste 70% of our produce, but it can be easily put into pigs as meat processors. We can also extract the fat first and put it through insects first as a protein processor. This can then be fed to meat processors and produce something delicious.

Ever heard of free range gras fed cows in the Alps? The land is basically unfarmable for anything else. These cows are super delicious.

The vegan diet requires a lot of different materials shipped from all over the world to meet a sufficient nutritional baseline. Due to climate shifts and wate consumptions, Farmland for such specialized nutritions of high value becomes more and more rare. Sure we can easily reach our calorie intake by producing a ton of highly processed starch, with a minimum of farmable land, but we would start to severely reverse Flynn's effect because of it.

scantis··on [dead]
According to scmp china is an autocracy?

What is a virtue in a democracy is a dissident in an autocracy.

scantis··on Ask HN: Why do profs supervise PhD students not smart enough to ever be peers?
There is a monetary compensation in most fields. Even though the PhD student might be bad, it is all his doing and choices, he can freely learn new skills and develop himself.

Even a horrible degree can lead to a comfy job.

It depends on the field, in chemistry it looks like exploitation in engineering it's totally different.

In art, languages, etc getting paid to learn is already a cherry on top.

scantis··on Ask HN: Can AI detect mask mandates?
For the x-ray AI this is possible because a lot of data exist with clear results. One famous model included the patients information in full text on the x-ray images, which the AI quickly picked up on and which was overlooked by humans.

I believe this was with cancer not race. With a good data set you can create a projection with a mathematical tool that has capabilities to predict something. This sometimes called an AI, but includes a variety of methods and recipes in machine learning or adaptive filtering processes.

Mask mandates already are not providing a clear data set. I don't think an AI can help here. There are some studies indicating a 10% decrease in transmission on average, but are those studies are riddled with confounders.

There are various types of masks and different situations. With highly trained personal in full protective gear transmission still reached up to 70% in some settings. If enough viral load is present it is very easy to get infected with the slightest mistake. So this would count for 30 % or more in transmission reduciton, which is better than 0% without masks.

In public, where people are even less capable to wear these mask correctly, this drops below 10 %. Which is basically in the statistical noise for this kind of thing. You will not be able to predict or notice a 10% change in an exponential growing curve that easily.

Especially if it's riddled with confounders and weird onset behaviour.

scantis··on Ask HN: Content about the Scientific Method?
They don't.

Usually you have a general topic you like to talk about, but you can't because it is all well known. So you have to give it just a little twist.

This can be a new method you try, for example a neural network that does some thing. You then explain the general topic, then give some Infos about the NN and may compare its success to an established method. This has been done in every field now, that people already get sick of it. But this generally holds, just apply an out of field method and compare. It makes for interesting content and you can regurgitate the known theory to get enough mass.

If you have hard data, that is not easily available, because the process to receive it is espensive, you can publish with just some basic evaluation. Just make it a tiny bit more shiny.

In your case with environmental modelling you should be in between the two. Just keep it simple and well struktured.

The scientific process is the art of adding a lot of very small steps. You contribution can be tiny if you already walk a well known path.

It's all luck and knowing people in the end anyway.

scantis··on I can delete my FB, Google, Apple and Reddit data. Why not Hacker News?
Most HN users are circumventing copyright restriction and paywalls to make content available to a wider audience. Weirdly enough they draw the line with citations, this is why so many projects are attributed to weird internet nicks.

Usually doxxing those nicks wouldn't result in financial compensation, but lots of legal trouble.

What you want is fringe and confusion to me, especially in this context. You control your nick and your comments are attributed to it.

If somebody else uses your comments for something useful, they can cite your nick.

scantis··on Anonymity No More? Age Checks Come to the Web
Well what is it? Youth protection or punishing them for circumventing age restriction and parental oversight?

Who is the victim and who is the offender?

The child exposing itself to the content or the internet not protecting it's content from the grasp of some user?

Protecting the offender from commiting the offense seems kinda dumb. Do we as a society are responsible for crimes, because we don't prevent them?

If a twelve year old wants to see some boobs, he will find a way. Making it more difficult will make it only more rewarding.

We would have colonized mars by now, if it had the same motivational power...

scantis··on Ask HN: Can world-changing industries still emerge from garages?
Sure, technology isn't about complexity but simplicity. The trick is to take a complex problem or process and simplify it, so it becomes cheap and easy.

Quantum computing is based of components of many small specialized company's, employing fringe process skillfully. I can build you some some BCI ( one way) with components for less than 5 euros. I don't know what supercomputing is, but if you want to rent a super computer or cluster it will be very cheap. AI has pretty much peaked and is just a general tool by now. It would be great for a simple project with high impact, if you got the right idea.

scantis··on Autonomous vehicles create new problems and solve none
Not really, autonomy is probably not the way to go.

One could easily drive all trains remotely, like kids playing with a toy probably since electric trains exist.

We still prefer human drivers all over the world, except for some systems. Those need to be very small or closed to be safe enough. Having a driver and personal has many advantages especially for unforeseen events. Autonomous vehicles may have the advantages in safety when nothing unforseen happens, but they can cause catastrophic chain reaktions. As critical infrastructure autonomous driving vehicles are an easy target, play them the right radar sequence and they will stop moving or endanger others.

scantis··on Paracetamol use during pregnancy – a call for precautionary action
When a woman becomes pregnant, everyone is only seeing a fragile infant that has to be protected from the environment.

That evolution already provides the infant with some very strong protection including two blood barriers to protect the developing brain is easily overseen.

The dosis makes the poison and there are numerous examples of addicted, underfed, stressed and overworked pregnant women giving birth to healthy intelligent childs, even in dirty and polluted environments.

Drinking a beer or taking medicine is not harming the child in any way, as long as it is done in moderation.

The paracetamol problem is an old one, because people tend to take to much of it, when feeling the slightest discomofort. Combined with coffein, aspirin and or alcohol it has a huge draw on liver and kidneys. You have to diffentiate between taking a pill once a month and eating one package per week. Both would be inside the recommended dosage, but are clearly different.

For pregnant women it is a bit more difficult than 9 month from modern comforts, so some little remedy once in a while can go a long way.

scantis··on Non-native Spanish speakers urged to use language in public to combat stigma
"Freedom of speech includes freedom of language choice. So, we are actually protected by the Constitution in speaking the language of our choice," Carr said. "And yet, we hear about violent verbal attacks, threats of deportation and assaults for speaking Spanish while brown, Black or Indigenous."

Those people don't get it.

Henry Drummond: I don't swear for the hell of it. Language is a poor enough means of communication. We've got to use all the words we've got. Besides, there are damn few words anybody understands.

scantis··on Ask HN: Constant electrocution from MacBook enough to cause You heart issues?
My wording was maybe a bit bad, but this really sounds like AC current leakage. When you feel it, it is above the action potential, therefore activating your nerves and muscles.

This could be due to improper grounding or faulty components. This is not normal and shouldn't be!

It can cause all kinds of symptoms, but the general consensus is, that if it is below the dangerous threshold of around 30 mA, there will be only discomfort but no permanent or irreversible damage.

Discomfort is lightly said, but can have a huge impact on your quality of life. Please do something about this and maybe complain to the vendor. Even though this is not seen as health risk.

There are some studies suggesting in vitro damage for all kinds of cells at low levels of current, you as a complete system will be very resilliant to this.

scantis··on Ask HN: Constant electrocution from MacBook enough to cause You heart issues?
It is at least plausible, that you could run an AC current over your arms and over your chest. This can cause a stimulus to your nervous system if the current is high enough to overcome the action potential.

A tingling sensation, muscle spasm and aching would be the cause for low levels of current and prolonged exposition.

But since you found the culprit, you would be easily be able to mitigate your exposure. Either by wearing latex or rubber gloves or proper grounding of your device, which should not shock you btw.

Above the action potential you muscles will contract and your nerves will give stimuli, which can cause tension and anxiety.

If you feel the shock sometimes you are definitely above action potential.

There is another threshold above the action potential, which will cause irreversible damage, heart failure or death. A residual current device is usually installed with your circuit breakers to prevent residual current above this threshold.

scantis··on Ask HN: What would happen if we did _not_ electrify cars?
Gasoline would run out in about 50 years, but we have been wrong about this prediction so many times over, that it probably last forever. We would burn the gasoline to power anyway to fuel the electric car, so it is not an issue at all. We would switch to synthetic methanol, that can be produced very cheaply with CO2, water and energy. Bio fuels have the disadvantage of actually burning potential food supply, Haiti had to suffer great hunger because of that once and we should not repeat it. We may will and it would be very bad.

Without electrified cars, much less resources would be required to produce batteries and electric infrastructure. We would produce less harmful waste in the long run.

The battery electrified car does not have a better ecological footprint, as of now. It only has the potential to perform better, if we would use more renewables and less toxic and polluting processes... Which we also probably won't, cause we like our stuff cheap.

So nothing much will happen, but there is a big chance that not electricfying the car could be better for the environment and the climate. If we would act smart about it.

scantis··on Closest known relatives of virus behind Covid-19 found in Laos
Let me give you the scope of the problem.

The genetic code is a redudant code, small difference in the code can still yield the same information. There are 64 triplets, start is one and stop are 2 and there are 20 coded amino acids coded with the rest. So 22 out of 64.

There is a direct similarity and a similarity of information. For redudant code the former is useless. You can have a direct similarity of 30% and a similarity of information of 100%. (Considering a 1:3 redundant code at its worst, DNA performs much better)

There is also a third layer of redundancy, that is still under investigation, where certain sequences of triplets can be permuted and still yield the same result. The order of assembly is redundant for some big projects also, allowing for the code to be permuted in chunks as well.

So we are looking for the similarity of a redundant code that allows for permutations on two scales.

Without considering how the measure of similarity is taken, something being X percent identical means absolute BUNK. It can not be a direct comparison of the code.

SARS COV2 ~ 30000 pairs HIV ~ 10000 pairs Spike ~ 4000 pairs

The SARS COV 2 virus has 3 times the code of HIV. You are also dealing with different sizes.

But one can cut everything between start and stop, translate it to amino acids and permute the result into oblivion. Whatever is left can be compared by a huge variety of measures.

But when working with it, you just sequence your stuff, feed it into the commerical software and click compare.

scantis··on Britain Signals Intent to Revert to the Imperial System
Apparently you may order 1 oz of whiskey and get 25mL in England and Whales, but 35 mL in North Ireland and Scotland.

So I say they think differently about it, but they all know.

Maybe someone from UK can elaborate further.

scantis··on Ask HN: How can I bring in some money soon (very) as a programmer?
If you need cash quick and you are punctual, good with people and focused on the task, you have a lot of options.

There are a ton of jobs in the service Industry, in healthcare or transport.

Just get any job to pay the bills, there is no shame in flipping burgers or washing the old. Since you can view it as only temporary, like for 3 month or 6 month period you can give it your best shot. Try to be outstanding and try to get the best performance review possible.

It is often easier to switch jobs, than to apply from nothing. A good performance review in a totally different field can do wonders for interviews.

Show human resources something they understand.

scantis··on Ask HN: How would I make 3 millions euros in two weeks
3 Million is odly specific, you need get 1 € from about 1 Million people.

Set up a company and some basic Hompage, with impressum and contact information and complaint form. Your company sells heartwarming personalized messages. Set up banking form on the homepage for your services, to collect occasional personal data. Just send some heartwarming email, with a picture of a dog or flower or whatever.

Withdraw 1 € from around 60 Million personal accounts, for services from your company. Get this information from some other shady buisness, there are also some data bases online. Just shoot it over your form to be safe.

Create some aumtomatic responses to your complain email with some heartwarming messages, must include cute picture for legal reasons. When a customer writes a few times have an apology ready and send the euro back, but take a 5 cent transaktion fee. Be very polite.

Since it's only a euro and most people won't look at their banking details anyway, you target sum could be safe in two weeks.

You should be able to get at least 3 Million out of it, that you can use to stay out of jail as long as possible.

A group did this back in the day, but they couldn't get the money from the account. Since it belonged to an old couple, which was charged, but it all was dropped in the end.

They collected receeds from gas stations to get the info, this should be easier by now.

You can get this money back from the government, if you fill out a form and for a small working fee. Astonishingly, very little people reclaimed their money.

scantis··on Ask HN: How to get almost complete electronic components database for offline
Just download the library of the distributors.

E.g. digikey, mouser, farnell... etc

There are crawlers available and projects that download all information and change them according to your needs. Picture and datasheet seems kinda fringe though.

We will only buy your component if all information can be easily integrated in our design process. Depending on the design software used, we receive component libraries of available components, including step and spice files, directly from the vendor.

Any good vendor will give you his full component library for free. You can just ask them, they may even tailor it to your needs.

scantis··on Ask HN: To what extent is Transhumanism an ideology promoting genocide?
The idea of improving humanity by optimizing breeding has the obvios shorthand of getting rid of the interior by killing them all off. In transhumanism murder and forced sterilization are necessary progress humanity beyond it's genetic limits.

I wouldn't fall as short as concluding that is an idiology promoting genocide, since inferiority spans above race and ethnicity. It is the inherent common ground of being human.

Transhumanism is promoting more then just genocide. To transcend our humanity it wants to rid us of it completely.

Transhumanism is an ideology with the goal to move the human common ancestor point further into the future.

Genocide is just one of a multitude of tools for this.

Transhumanism is the fevered dream of people who do not grasp the limits of our technology. People who think we are just 100 or 1000 years short of mastering gravity and bend it to our will. People who think we can genetically construct the perfect human somehow. Really? Have you ever seen our software mess at all?

It is a dangerous ideology, that denies our most inherent human trait of being a failure. Btw. the failures and inferior people have been the ones, who improved our technology, science and so on. Take 10 software developers or engineers that are any good and throw something at them. Those who scream or try to protect their equipment are the brains.

Transhumanism is oblivious to this simple evolutionary trick of cooking up genius from a pile of inferior slime.

scantis··on Anyone know the name of this signal processing discovery? I’ve been using FST
What you describe is the Hartley transform. In your case it is the fast discrete Hartley transform.

It is an involuntory form of the FFT.

It is a very interesting find indeed.

Edit: fyi it retains all properties of the FFT of course.

scantis··on Ask HN: How to cope with the death of a dear person?
There is nothing you can do for yourself, except giving yourself the time and space. There is no magic potion for it, it just takes time.

Just know there are always others who also have to cope with the same loss in their own complex ways. Some people cope by changing their memory and describe the characteristics of a person completely differently, alienating your experience. Nobody will correct them, because everybody becomes so respectful towards others. Without real notice this damages relationships in the long run. It shouldn't, but at some point you can't stand the people close to you and their sadness and twisted polished stories anymore.

There is no malice to it, we all experience things differently. Do you ever really know a person? A whole life is quite a long time and some of us only see some facet of the life of others and there are things we don't want to see.

It seems strange, but the dead really don't care about this world anymore, it is only for the living. It is not about respecting their whishes, it never was, the dead are owned by the people close to them and they even decide who that person was. It is about what they need and that is the unimportant stuff you should forget anyways.

Many great mathematicians are buried with citations, they already regretted when they were alive.

But after a few years and without the haze of pain and emotions, real human and normal stories and memories can emerge again. If you lucky, somebody is there who can acknowledge them with a smile and a mind falling back in time. That is the good stuff.

May your experiences be different.

Your time machine is between your ears, it is very powerful and can be tainted by emotions and pain, so be careful when to use it out loud.

scantis··on The Hyperloop May Disrupt More Than Just Travel - Bloomberg
It is a pipe dream. We already have cars, that already change the "game" as a few small pods in a giant open network.

The slight advantage of reducing wind resitance has to take on so many disadvantages, why would anyone believe that the Hyperloop would ever be viable?

scantis··on Ask HN: Is anyone worried about the monetary mass?
I'm not too certain, I am a scientist not a business suit, so I could easily be wrong... but ... From my point of view the crisis of 2008 came by calling the bet and seeing it wasn't backed up by cash or collateral. This was circumvented by increasing the cash flow and saving the banks at that time. In 2009 the US gave stimulus pack to restart the economy, since only saving the banks didn't help anyone else.

So the resession was healed by providing more moving money and everything bounced back.

This is what we see again now.

So the system is actually holding up because the amount of money is increased. This is not the symptom, but the cure.

This way everything can go on as it is, but you are right, there can be more effects. Although I'm not sure which.

If the cash flow goes away so do all products and people starve... This is avoided by printing more cash. At least that is the theory and it seems to hold, for now...

Again I could be wrong on this.

scantis··on Ask HN: Is anyone worried about the monetary mass?
This problem is world wide. Nearly all countries print more money, while the global economy reduced it's output by 10% on average.

This is why we can not see the effect yet, because everything is still somehow in a balance.

Around 2008 there was about 4 times more money than things you can buy, now we approach 20 times and over. So this is not a new problem.

This money is stored somewhere and not part of the economy, so this usually does not matter, but the implications are crazy. If you look at Tesla for example they are worth more then the next 6 biggest car companies combined, while only producing the tiniest amount of product and having very little people employed. This will continue and continue, over years people assumed it would crash and have been wrong.

This makes no sense to me, but having more money and less stuff is actually a booming economy in the making. The problem is, the money can not be used right now. The world economy is stalling.

But give the money just a place to be stored or a product worth buying and boom its value goes through the roof. Housing, rare materials and companies like tesla will suck up money like crazy for now... Other then that nothing much will happen for now.

scantis··on Tesla 10x times safer than average car
Safer than old cars, they compared with all cars including Teslas with and without autopilot. Assuming with autopilot engaged reckless driving is severely reduced and the small number of Tesla's on the road, it is not that impressive at all.

Teslas crashes are more lethal, which is expected considering all supporting structures are filled with lithium batteries.

They count accidents, which includes every little fender bender, on crashes with severe injury Tesla is closer to old cars. There is no EV in top 50 survivability cars at the moment.

So good news, you have less parking accidents with a Tesla and avoid some other stupid ones, but when you crash hard you will burn to death.

It is a good deal.
