scantis··on Bitcoin’s Last Stand
"It does not generate cash flow (like real estate) or dividends (like equities), cannot be used productively (like commodities) or provide social benefits (like gold)."

What are the social benefits that gold provides?

scantis··on Ask HN: Which is your favourite instant noodle?
After intensive study sessions

Mama shrimp creamy tom yum with additional creme cheese, must be eaten standing up, preferably over the sink and under strobing flourecend light for maximum effect. The illusion of nurishment combined with the freshness of lemon grass.

scantis··on Ask HN: Are privacy concerns around Microsoft Windows 11 overblown?
That is not true, Microsoft is still widely regarded as the industry standard. It doesn't matter how horrific their products are or become.

I have so many measurement devices that run some form of windows on them and are impossible to port to anything else. I still run windows XP and 7 in private networks for some machines and still have to use windows 95 to rewrite some 8bit routines to floppy to run some ancient controllers.

Not because I want to, but because I have to.

Windows 11 is a giant problem, as it uses ridiculous amounts of ram. Around 2025 we will not be allowed to have win10 on the network.

So this is serious question for some, is windows 11 any good with privacy? Well I certainly hope so, as I'm not in the position where I have any choice.

scantis··on Revisiting a controversial question, looking for honest feed back not shaming
What does well understood mean in this context? The mRNA enters the cell because of some addition to it, which seems to be the key here. What is exactly coded in front of that spike protein to enter a cell and what happens with it inside the cell? Is this part required to enter the cell just discarded?

The cell starts production of viral protein by copying the mRNA again and keeps doing so for while. Then it somehow stops... What exactly stops this process, except for heat shock?

Are the cells injected with the mRNA gobbled up by the immun system or does it stop on its own to produce the viral protein?

How does the viral protein leave the cell after it is produced inside of it? For a production of a virus it would stay inside until the virus is fully assembled. Is there a trick to the mRNA stuff, that makes the cell produce the viral particles outside of itself so the immun system can get to it?

Or is the cell bursting at some point when it is completely overloaded with viral protein?

scantis··on If bumblebees can play, does it mean they have feelings?
There is a lot we don't understand in nature. Maybe the humble bumble bee has deep philosophical thought about it's own existence and requires escapism through play. There is a viral video of bees opening a soda bottle.

It also could be that those wooden balls just had the right odor, gustatoric or sensoric properties to be very interesting to them. What can they do besides cling to it and move around with it anyway? Colored wood, that hasn't been sufficiently cleaned and maybe touched by unprotected hands in an otherwise dull environment, could be a wealth of information to them, that triggers various routines. Maybe it is behavior to explore, while leaving again a chemical trail, that makes the object more interesting for other bees that follow. The observations based on the age or gender of the bees could have a lot to do with previous interactions the object had.

Ants may run into a death spiral, when their chemical path closes in a loop. Insects are sophisticated sensors, that communicated chemically and based on simple algorithms to great success.

So there could be just algorithmic behavior behind this.

We are indeed still far of from bumble bee football, but with the right chemical trails, who knows what could be possible.

scantis··on Ask HN: Is AI for online segregation ethical?
Interesting thought. I think this falls in line with explaining mistakes to people and is quickly off topic to op.

If AI could help people to bring their point or grievance across in a clear manner, this would be the opposite of a shadow ban. This can be done transparent, in Form of a suggestion.

E.g to write penis as p.e.n.i.s. to make clear that proton enhanced neutron induction spectroscopy is abbreviated here, might be helpful to some.

AI can create a feedback loop ethically, if it makes itself know as an AI or automated system or Eliza 2.0. The user can choose to just opt out or mash on his keyboard as he pleases, as we do since 1964.

That is all ethical, but deceiving users and trapping them definitely isn't.

scantis··on Ask HN: Is AI for online segregation ethical?
Censorship is already unethical. One would have establish a need for censorship first. Can a book be written, that causes people to become a danger and thus needs to be forbidden? Is it even possible that a text on a computer screen can cause harm to someone?

I'm not aware of this and any argument for censorship is usually quite a long stretch of hypertheticals.

For violating TOS people should know what rule they have violated. For example doxing, spamming or just being insufferably rude. Punishment without explanation or reason is obviously unethical.

I think shadow banning people and then actively keeping them in loop can hardly argued to be ethical. Shadow banning itself is barely ethical.

scantis··on Ask HN: What are your best life hacks/best tools in life/time savers?
Laying out my clothes and everything I need for the day in the evening. After waking up my brain takes hours to boot properly. Selecting the correct clothes can take long and it is way to difficult to even figure out what work requires that day. I zombie walk into the bathroom first thing and start the basic hygiene routine, then I put on the clothes for the day.

Before I know it I'm at work and ready.

I figured that out embarrassingly late and it saves so much time.

scantis··on Ask HN: Are there recorded instances of people being framed through hacking?
I remember reading this on HN a long time ago, but I can not find it anymore.

The method was explained in detail and concerned the source engine for this exploit. When I search the web for it, I only find articles of the game being banned in China, this feature being removed and then coming back as a monetized feature.

Also searching for this felt extremely sparse.

Maybe you are right and this never happened and it is just some clever internet hoax. The insta ban thing seems far fetched.

But I am certain this was used to troll, protest and circumvent censorship with gusto and must have had some consequences.

scantis··on Ask HN: Are there recorded instances of people being framed through hacking?
The usage of locally forbidden material in online gaming, to insta ban opponents or as a form of protest is a well known trivial hack. Some games allow to spray an image file to a wall, the picture is downloaded by all players. Locally enforced censorship then causes disconnects and even legal repurcussians to some gamers.

In some countries you are strongly obligated to make contact with illegal images know to the authorities. Failing to do so is punishable.

Such an attack is as trivial, as annomously sending illegal material to the target, depending on the country. There are thousand of cases of minors sending nudes and causing legal investigations. You find articles of parents sending pictures to doctors and being banned from online services, which are known.

Other social attacks, such as giving out free USB sticks with incriminating material are thinkable. Allthoug I am not aware of this being proven to have happened, one can find cases where people used this as a defense.

People providing free uncensored internet by running a Tor node are known to have lots of legal troubles because of it, with different severity depending on the country. Even making it to no flight lists.

Illegal pictures might not be viewed by the public. A government could just claim they found them on your device and may have a way to exclude them to be viewn by anyone. So an individual may have to start a defense from the fact that illegal material has been found on a device, without a chance to ever see the image. Again depending on the country and legal system, there might not even be a need for those illegal pictures to actually exist. Here a document from a governmental entity suffices.

scantis··on Is opening and filming lost luggage a morally defensible act?
Generally you could just take any luggage from the conveyer belt and may get away with it. Which allows for a much targeted approach of stealing with the intend to shame or harm somebody, an immoral act, that is illegal.

My luggage was pillaged for valuables during a longer bus trip in Thailand, the criminals took a ride along in the luggage compartment of the bus. Luckily they only got my electric toothbrush and some shaving blades. Still...

Just have everything of value in your carry on and only check in things that can get lost. The bulk of lost luggage is simply this, stuff people don't value enough for the hassle to get it back, which is a pain with airlines. I have lost luggage on conferences and lost a really cool beany and umbrella because of it, I can't get anywhere anymore. No question, it sucks especially with airlines. The process of getting something back or compensation is very annoying on purpose.

Still I wouldn't assume that I could buy illegal or incriminating material from auctions of lost luggage or that such an transaction is generally immoral.

I'm afraight that if it is possible for one to identify the owner of auctioned lost luggage, one would be obliged to contact them about it. While using this for blackmail or shaming would not only be immoral, but also illegal in most cases.

The act of selling the luggage after some effort to find the owner, is not, I think.

scantis··on Is opening and filming lost luggage a morally defensible act?
Professional open the bag before the auction and try to find identifyable documents or illegal materials. There should be no way to clearly identify a person over their lost luggage, otherwise they are not given into the auction. Furthermore some time has to pass, so there is no claim on the specific luggage item. Only then the luggage is truly lost and without identifiable owner.

I really don't see a moral problem with this. Allthough you have a point and this can be done immorally, if these measures weren't in place. Does this put your mind at ease? Or does something else needs to be done to ensure the privacy of the previous anonymous owners?

scantis··on As EU is asked to mobilise all available energy, anger at Germany grows
It is still incompatible to our current system. Allthough there are very efficient solution to recycle nuclear garbage and bring it on faster decay chains, this process is messy and nobody wants to really touch it. We have the capability, but there is little money to be made and it comes with insane liabilities. Politicians would need to create a robust and efficient framework, but it is more lucrative to move the waste around with ever exploding costs and fear monger towards the public. We will never see this clearly.

Oil can be bought by the barrel and moved around the globe quite easily, while the carbon footprint can be blamed on any of the producer or you the customer. Wind energy and solar can be injected without much care and little regulation. Both can make a ton of money and need little care. A nuclear driven hydrogen and methanol economy on the other hand, that disposes of the waste with complicated processes, is expensive, complicated, thankless and nearly impossible. Especially with an ever changing political framework.

scantis··on Ask HN: Which strategies work best to reduce/eliminate alcohol use?
I use a simplified point system to keep track. I rarely drink, but used to escalate when I do.

I usually calculate a beer, a shot or a glass of wine as a 1. Big or strong beer 1.5. My favorite cocktail is a 2.5. Reduct one point per hour and 1.5 per hour with heavy movement.

Sober is strict 0 points. Non drinking is 1 point. Work related drinking, I never go above 2-3 points. Exception is the Christmas party, 6-8 points. Out alone, usually never above 5 points. Family gatherings 1 point per family member for small gatherings, with a variety of bonus points for certain people.

I consider more than 8 points to be problematic to keep track of the point system.

scantis··on [dead]
But what if it really was simple? Just having smaller classes, a better school lunch and a better outlook for the future could potentially half school shooting per decade? Which would be huge and is maybe measurable. School shootings are extremely rare.

While also benefiting the million students in despair, who share many significant traits with the FBI standard issued 52 page school shooter, that aren't violent?

For every shooter there are a million mistreated students, who choose to suffer in silence. So it will take a lot of effort to reduce the amount of very fringe outsiders, who can commit the willpower to kill their own peers, but somehow lack something to use this willpower to improve their own situation in a positive way.

I like your general rule and there is actually no simple fix. But there are simple things you can do, that improve a situation a lot.

Making schools less hateable isn't a bad idea and probably easier to achieve, then getting rid of all available weapons and everyone on happy pills.

scantis··on Carbon capture train concept could clean air as it zooms along the tracks
"CO2Rail is still in the pre-prototype stage and proceeds will be used to help transform the CO2Rail vision into a commercial reality"

Most certainly a scam. Over the thumb, not viable.

scantis··on Ask HN: How do I deal with high levels of formaldehyde in my apartment?
Work space is 0.37 ml/ m^3 living space is 0.1 in Germany. Translates to roughly 370 and 100 ppb over the thump.

If I'm not mistaken.

So this isn't nice, cause you touch upon the threshold. You keep an eye on it and you are aware. So you will be fine hopefully it drops further. Your body also produces this stuff, so there are urine tests I think.

It can also come from candles and cleaning agents.

scantis··on U.S. death rates show how politics are affecting public health
They address this and find the same gap in the normalized subset of rural vs metropolitan areas. The gap goes from 5 point to 66, which is slightly less.

democrat 143 counties, n=91 809 974 to 156 counties, n=133 796 619 And republican 292 counties, n=61 407 202 to 280 counties, n=46 244 883

So overall health is improving, but it is improving more when increasing sample size. It is normalized, but still different things are compared.

Thanks I didn't know all that about democrats and counties, seems more involved then I thought.

scantis··on U.S. death rates show how politics are affecting public health
Okay so the counties flip, the democrats loose counties overall and gain 40 million ish people?
scantis··on U.S. death rates show how politics are affecting public health
Why are the democratic counties nearly halfed over the study, while the republican counties increase slightly? While the number of people increase? Are democrat counties growing together?

"The study period covered five presidential elections from 2000 (673 Democratic counties, 132 833 397 population; 2439 Republican counties, n=147 957 141) to 2019 (490 Democratic counties, n=176 971 611; 2622 Republican counties, n=145 413 920) (supplementary tables 1 and 2)."

scantis··on Ask HN: Bothered by Loud Music in Restaurants?
General loudness has limits since it can damage hearing, assume we are always below discomfort using damping if necessary. It is said that 6dB SNR would be enough to still follow a conversation, but there seem to be some exceptions to this. Even if the system, ear, drum, hammer, cochlea and nerves are fully intact, older people seem to sometimes loose the ability to differentiate properly between different sources. I don't assume you are old, this effect is quite complicated. I don't use a hearing aid, but I foolishly assume it will not improve SNR only general loudness. Like most amplifiers would.

There are some known exceptions, such as musicians, who can differentiate quite well. Which lets us assume, we can better this by training hearing properly.

For this music seems to be a key, since you can try to focus on specific parts like single instrument and try to ignore others, even though they are all present. This is done by the calculative power of our brain and happens in the signal processing stage of it. Not a hardware problem. It even uses additional information.

During the pandemic lots of people wore masks and I had trouble understanding many of them well. This isn't mainly a SNR problem, for me to get good differeniation seeing the persons mouth helps.

Sometimes I don't understand what people say, they repeat it and repeat it until my brain moves to the right place and everything is immediately clear.

I enjoy the occasional industrial death metal concert, here I noticed even with earplugs, shutting you ears with your hands, you can very well hear what a friend yells directly at you. Construction worker with earmuffs using insanely loud equipment, still exchange information by yelling. So even if an insane amount of noise is present and then damped to safe levels, direct communication is viable if SNR is good enough.

The problem is the processing stage, which requires additional training.

At least that is my theory. I assume loudness in public is at appropriate levels otherwise people would complain.

scantis··on Ask HN: Food Addiction
Those things are fun, I did a lot of abstinence experiments myself when I was young. I learned that I don't want any constraints for food ever.

Eating only powdered protein low quality and fake stuff will mess you up and your kidneys. So I once choose coma patient food. It comes in many varieties for all ages and is cheap in bulk. It is complete, tastes medium awful and you only feel horrible for the first few days. Then just drained, zombified and mildly happy until you can't take this stuff anymore. High fibre content is important.

scantis··on Is the Internet OK?
Squids seem to belong to the class cephalopods. Coffee comes in 3 classes, arabica, robusta and liberica. The last one is rarely used and autocorrect messes with it.

Using the search terms cephalopod and liberica on Google scholar I only get two results:

[1] A Vernon Harcourt, Rudolph Koenig The Journal of the Society of Arts 25 (1285), 795-806, 1877

and

[2]ROYAL MICROSCOPICAL SOCIETY. DMS WATSON Journal of the Royal Microscopical Society, 1906

Why is things?

scantis··on Ask HN: We do CS profs think programming is easy while SE profs say it is hard?
I think in theory you just assume optimal implementation. In engineering this is more of a luxury.
scantis··on ‘Enforced childbirth is slavery’: Margaret Atwood on the right to abortion
Yes, it isn't, otherwise this thread wouldn't exist.
scantis··on ‘Enforced childbirth is slavery’: Margaret Atwood on the right to abortion
Seems to me anti-slavery is an amendment to the constitution. So it is a right not a law. It doesn't dangle from a previous SCOTUS decision and half assed legislation.
scantis··on ‘Enforced childbirth is slavery’: Margaret Atwood on the right to abortion
This is completely blown out of any conceivable proportion. The supreme court is correct, they should strike their previous decision and let the lawmakers create the proper framework.

Weird to equate this to slavery. These people actually think the supreme court revoking its previous ruling will ban abortions outright.

scantis··on Elon Musk and the Tech Bro Obsession with 'Free Speech'
I also have trouble with it. Become an intolerant society before you become an intolerant society seems like a strange premise.

I think for me it comes down to the point, where the tolerant end up being destroyed.

How does this happen exactly? Shouldn't we focus more on that? Are we to destroy the intolerant prematurely before they destroy us?

How about just not destroying people, no matter the perceived tolerance or intolerance they exibit?

scantis··on Increased cardiovascular events in Israel during vaccine rollout and third wave
Would you like to discuss why they use Spearman instead of Kendall and if this negative binomial distrubition asumption is valid in this case?

It won't have any effect on the final result, which basically states that the data set is insufficient.

scantis··on Increased cardiovascular events in Israel during vaccine rollout and third wave
Looks like a straight forward article. Instead of a conclusion you are left with a discussion, which sadly is quite weak, but this seems to be the point. (As I understand it after skimming through it)

Basically you have a data set and some statistical evaluation. The gabs are filled with some medical and statistical "Mumbo Jambo" I didn't read. Seems professional, the graphs are pretty clear cut, which is nice.

The discussion basically states that the data is flawed for the purpose of making clear connections and urges the necessity to provide better data in the future. They aren't even able to make their derived call data public, due to privacy laws in this case.

They are absolute right and have a valid point here. No reason not to publish this and it conveys some important messages.

We should gather better data and find a way to share it, without touching on the privacy of individuals. A very difficult topic I personally wouldn't touch with a stick.
