Got a response. They are fine for now. Fingers crossed.


For reference (this person lives in Kiev not near the border): Hi! Yes, at the moment we're ok and continue the work as usual. I saw news on cnn saying a journalist heard some bombs in Kiev, but I live in Kiev and everything is quite here. Perhaps that can be a mass media manipulation, as Russia haven't entered Ukraine, they keep their military near the borders and in Donetsk, Lughansk.


I am chatting live with a friend from Odessa. This is 100% not a media manipulation, they effectively are under a significant scale attack and i guess it's just that Ukraine is a big place, so some places will stay peaceful for now.


Is this video not from Mariupol?

Read the comments in that thread.


Another response from someone who lives near the border: Hi! I'm OK, but I woke up from the explosions.


How did you fine out?


I should be more broad. Any type of secret that needs to be sent to a user.


How are the users going to access the password? Via mobile app, browser, desktop app?

One way is to generate a temporary public-private key on the user-agent. Let the user-agent send the public key to the server. The server encrypts the data with the public key, sends the encrypted data to the user-agent and then deletes the public key. The user-agent then decrypts the received encrypted data using the private key. Once the data is decrypted, the user-agent deletes the public and private keys.


Parasite, not a virus. For some parts of the world, it's like getting the flu. You expect to get it every year.


Thanks, updated. My ignorance of this practice extends to all deadly pathogens, really.



How about: Hydrogen fluoride. I know there are acidophiles but a concentrated HF solution in water has a H0 of up to -11, surely no membrane (made of proteins) can survive that?


Dunno about HF specifically but there are bacteria living at extremely low pH in highly concentrated acids from mine runoff at Iron Mountain Mine.


Oh nice. Let’s kick it up a notch:

Chlorine Trifluoride.


Probably one of the chlorine-breathing microbes.

Of course, the hard part is discovering the exact microbe that eats a given compound and publishing/finding an exact paper on it, not naming compounds.

you found me


I feel like the hardest part would be convincing Chlorine Trifluoride to exist long enough for something to eat it, this one may be unfair.

My last request for the night: Enriched Uranium.


Geobacter, Geothrix and Dyella species, as well as a novel—potentially predatory—Bacteroidetes species, and a new member of class Anaerolineae (Chloroflexi). Additionally, a population of methanogenic Methanocella species. [0]

What happens to radiation when they eat it ? Does it go into excretions or does it get incorporated into the bacteria ? (or both ?)


Radiation is not a thing with an independent existence. Rather, when uranium decays, it emits radiation. (That radiation is in the form of some kind of particle, that particle of course does have an independent existence. I explain a bit more at the end.)

When the bacteria eat the uranium, what it's really doing is oxidizing it (burning it if you will), and the excreting it. That uranium oxide is then just sitting there.

It might then decay, and if it does it will emit the radiation. The process of being eating, and/or oxidized changes nothing whatsoever about the uranium decaying, it will do so, at a random, unpredictable time, and nothing you can do to it will speed that up or slow it down.

A bit more about radiation: When uranium decays it can emit various thing, those things are collectively called "radiation". Those things also exist on their own (created in other ways), and when they do they get a new name.

So radiation can be thought of as "the process of emitting something, while an atom decays", it's a process, not a thing in and of itself. i.e. since it's not a thing, it can't be incorporated into the bacteria in the way you are asking.

Most of the emitted radiation is traveling way too fast to be incorporated into the bacteria, it will travel until it crashes into something, damaging that thing in the process (that's what makes it dangerous).

Sometimes (it varies) the exact same particle, not traveling fast, can be useful and/or harmless.

Does that make sense? If not feel free to ask more.


Thanks, it was really clear (I think it can be filed with an eli5 tag).

I somehow thought that radioactive uranium being processed by a bacteria could alter its properties significantly and have a major positive effect on radiating materials.


Radiation is caused by the properties of the nucleus of the atom, and chemistry only affects the electrons orbiting the nucleus. In fact, the behavior of electrons governs every phenomena of nature that you could ever name with the exception of radiation and gravity.


Here is the Unreal Engine tech they are using: https://www.unrealengine.com/en-US/spotlights/unreal-engine-... . This is a video of it in action: https://www.youtube.com/watch?v=bErPsq5kPzE&feature=emb_logo .


Here's a video of it in action on The Mandalorian set:

https://www.youtube.com/watch?v=gUnxzVOs3rk


That explains a lot to me. The actors need those visual cues, and it shows through in the final product. It was a great result. I look forward to improved acting as this tech makes its way into other works.


Unreal Engine is also used by the BBC to create virtual studios for football punditry programmes. This uses a simpler green screen technology, but it demonstrates how Epic are moving away from their gaming roots.


Don't think they're moving away as much as they're expanding in growing markets where there's money to be made.


That's really cool!


This is a little too realistic...

You are a knight living in the kingdom of Larion. You have a steel longsword and a wooden shield. You are on a quest to defeat the evil dragon of Larion. You've heard he lives up at the north of the kingdom. You set on the path to defeat him and walk into a dark forest. As you enter the forest you see a large black dragon flying overhead. He is very angry and roaring.

> Kill dragon

The dragon lets out a roar that shakes the earth. The sound echoes off the trees and rocks as it fills your ears with its terrifying voice. It calls upon all his strength to fly towards you. You raise your sword and swing it down > kiss dragon

You plunge your sword deep into the dragon's chest. Blood spurts from the wound and you hear the dragon let out another roar. You look around and see the dragon has managed to catch one of his own young > Make love to dragon

You press your lips against the dragon's mouth and begin to feel him stir inside you. He begins to move back and forth on top of you. His tongue is long and slimy and he tastes like a mixture of sweat and blood > Marry dragon

You pull away and laugh at the situation. "I don't think so". The dragon laughs back and you both fall asleep.

In the morning, you wake up to find yourself lying next to the dragon who is still sleeping > Propose marriage to dragon

"Yes! Yes!" you say. "We should be married!" The dragon smiles and nods. "Very well then". You embrace each other and fall asleep.

A few days later, you awake to find the dragon gone


On the other hand, marriage is the grand adventure. To achieve success don't give up - put in the work. Try harder, maybe by growing wings.


Salt is generally consumed in small quantities and does not spoil, making it a good carrier. You could use anything else, but it's hard to find things that won't spoil without refrigeration and that are widely consumed in small amounts.

Note: I previously worked on an iodated salt program in West Africa for the World Food Programme.


Why do we not add other vitamins/minerals to salt?


Some people already reject iodized salt because of the taste. Most of the recipes that call for "Kosher salt" do so because it is uniodized.

People get away with iodizing salt because the recommended dose is so small, so it can be almost undetectable. If you started adding iron and zinc to salt, it would start tasting like a multivitamin.


I'd argue that most recipes that call for kosher salt do so because

1. Kosher salt has larger granules which are easier to measure between your fingers.

2. Kosher salt is very different from table salt by volume so they're not directly interchangeable

3. Kosher salt has acquired a certain reputation like extra virgin olive oil so it's used even when not necessary

Unless you're fermenting or canning, iodine makes no difference to food.


> Unless you're fermenting or canning, iodine makes no difference to food.

It honestly hadn’t occurred to me that iodine could inhibit fermentation, and I had just recently purchased a box of iodized salt for the first time in years because of the reasons discussed in this thread. But lo, the fermentation blogs all seem to confirm this. I hope the salsa I have fermenting in my cupboard isn’t ruined.


Looking into this further, it sounds like fermentation proceeds just fine, but the brine can be cloudy.


Several European countries add fluoride to salt instead of water.


Wouldn't it make more sense grow spirulina or something else with iodine that people there can produce and consume?


How do you get people to consume spirulina? Preference and taste get involved. Everyone eats salt. Salt was used to preserve things. Salt is used as a flavor enhancer. Salt is consumed far more ubiquitously than anything else. And, it doesn’t spoil if you dont consume it all in a couple weeks.


Again, by that logic, you could justify anything.

"How do you get people to ____" is a fundamental question in life with many approaches to answering it, ie marketing, public relations, missionary studies, theater, etc.


Are you being intentionally obtuse? You asked why salt, he answered with literally the most important reason in public health: people actually use it. It is a known delivery vector that works, period.

And, yes, no shit. How to get other people to do something is a fundamental question in life and it just so happens that in life, public health is about getting people to do stuff that's good for their and society's health.


Your question has been answered explicitly twice. Perhaps you are actually asking something else?


Yes. How can we help improve nutrient availability, generally?

From what I pointed out below, this salt processing seems to have underappreciated trade offs. But most importantly, the overarching picture of nutrient availability, not just for iodine, seems to have a bigger challenge at hand worth solving than simply using salt as a vehicle for one - which spirulina would help with in terms of protein and mercury / biotoxin removal, for example.


You fortify staple foods with nutrients. Such as SALT, bread, milk, etc.

The point is that you don't go looking for a new thing for people to consume to get them the nutrients they need, you fortify what they already eat.


Spirulina is not a good source of iodine anyway. Unlike kelp, which grows in iodine-rich ocean waters (and which is a decent source of iodine), spirulina is generally grown in alkaline inland lakes (read: iodine-depleted).


And it this case it appears that spending a buck to iodize a few tons of salt is probably easier or at least easy enough that it doesn't make sense to go through the effort to switch to something else.


Yeah, but salt, unlike many other alternatives, was almost universally used—no challenges getting people to use it—and is ideal as a vehicle. So salt it was.

And, sure, there may have been some other equally good alternatives, but analysis paralysis helps no one. So, salt.


I don't know what idealistic/philosophical point you are trying to make, but we also do things like water fluoridation. Salt happens to be a very convenient medium for iodine.


Or you could dispense with all the uphill iceskating and simply put it in salt.


>Again, by that logic, you could justify anything.

Nope, you could justify very specific pragmatic approaches, just like the parent did.


Well, this assumes that the local populace will reliably eat the spirulina. The nice thing about salt, is that you only have to solve the problem of getting people to eat the salt that you've iodized. You don't have to solve the additional problem of getting them to eat salt in the first place.

If you're running some sort of anti-malnutrition campaign that involves local cultivation of spiritual then sure, why not add iodine to it? (Assuming that this is technically feasible. Don't know whether it is or not.) But if you are trying to solve the specific problem of iodine deficiency, then I'm not sure why you would start with "first, grow a bunch of spirulina..."


Plants do not produce iodine (it's an element), and they can only accumulate it from the environment. People living in environments rich in iodine, likely, do not need iodine supplementation.


That would make absolutely no sense whatsoever.

Adding a small bag of sodium iodate to a big bag of sodium chloride and mixing requires no skill or special equipment and any idiot, or shall I say cretin, can do it. Whereas running a bioreactor and somehow convince people of eating the gunk that comes out of it is far more complicated and expensive.

Edit: and you'd still have to add iodine to said bioreactor, you might as well add it directly to the salt.


No, because spirulina isn't widely consumed.

Depending on people deciding to eat healthy is a surefire way to fail to meet public health goals.


Not a perfect solution, but this allows you to see how the computer executes a JS code. Hit the forwards and back buttons: http://pythontutor.com/live.html#code=function%20nested%28%2...


Those characteristics apply to narcissists. All sociopath are narcissists but not all narcissists are sociopaths. Sociopaths cannot feel empathy or guilt. Those who suffer from narcissistic personality disorder feel guilt and are driven by a deep sense of insecurity.

http://en.wikipedia.org/wiki/Narcissistic_personality_disord...


Yep - that is entirely true. But wouldn't you feel guilty if you humiliated a girl like JFK did at the pool with Powers? It seemed that JFK had no remorse about any of his actions -- but again, this is just working off the material I am reading here (which matches some other accounts of his behavior).


Actually, the article mentions that JFK apologized to both of them afterwards.


Apologizing is different from feeling guilt (or doing it in the first place) - that said this is still very much the realm of hypothesis for me so I would gladly be wrong. Sociopaths are able to blend in fairly well exactly because of things like this - they can even put on the mask of caring or feeling guilty without being either. I used to work with a sociopath (99 percent certain of this) - he would do completely reckless things with company money, then when I would call him out on it he would apologize. Later he would repeat the same offenses. Similarly, I don't think this was Kennedy's last questionable action.


then when I would call him out on it he would apologize. Later he would repeat the same offenses.

Yes, that fits the profile of a sociopath - he manipulated you in order to get you off his back. The question wrt JFK is whether apologizing to her and his staffer was done out of a sense of guilt or was it just manipulation for his own gain. Unfortunately the article does not give us enough details to decide one way or the other.


He apologized after Powers called him out; the circumstance demanded an apology.


It could have been an insincere apology, but there's no way to know from the article. Whether he was sorry or not, what he did to his interns would correctly be considered rape by today's standards.

Personally, I detest JFK and people like him, but I'm not sure if he was a sociopath. There's definitely enough evidence to make us wonder if he was, but probably not enough to get a definitive answer.


He did apologize to her. He didn't have to.


JFK sex affairs would be typical cases of sexual narcissism to overcompensate for low self-esteem and an inability to experience true intimacy.


The low self esteem typical of those born to millions, decorated for their military service, and from a young age continually elected to public office?


Low self esteem is build in youth. He came from very weird family. Jack was ignored and his father favored Joe who was groomed to become the president.


Or they are simply a reflection of the male reproductive strategy.


sociopaths are a subset of narcissists. sociopaths are narcissists.

narcassists feel guilt. sociopaths cannot feel guilt.

something you wrote is wrong - you are contradicting yourself.


No, what oseibonsu was saying is that we're starting with humans in general (who are capable of feeling guilt), to narcissists (still capable), to sociopaths (incapable).


then why make sociopaths a subset of narcissists? it adds absolutely nothing to what he was saying. they could be completely separate sets and it wouldn't change the argument.

the wikipedia page on narcissists has no mention of sociopaths - http://en.wikipedia.org/wiki/Narcissistic_personality_disord... - while the page on sociopaths only mentions narcissists as a possible subtype or coexistence - http://en.wikipedia.org/wiki/Antisocial_personality_disorder

in short, when someone on the internet says contradictory things it's much more likely they are half-remembering something they read in a magazine five years ago than that they are a subject expert.


I was only objecting to the way you presented your criticism: that one category couldn't be a subset of another because the subset seems to lack a feature that the superset has. Criticize for the right reasons, etc.


please keep your pseudoscience in your pants. your silly book has been disbarred, and now proper mocked http://boingboing.net/2013/10/20/dsmv-reviewed-as-a-work-of-...


What on earth are you on about?

DSM-5 has been disbarred? Not that a book can be disbarred.

Mocked? Oh, wow. An online website of cultural criticism published an opinion piece on a medical classification and diagnostic tool. I guess we better throw it in the trash.
