Measles is the Winner by TKO


Measles is so powerful that after we defeated it with vaccines, it came back even stronger to infect our minds!

We might think of vaccines as a meta-defense, a meta-immune system, which could also be called Public Health or even just modern medicine. Measles has found a way to penetrate this defense.

The anti-vax meme is, perhaps, the first example of a disease making the transition from the biosphere to the noosphere, so that we now, in order to fight measles, we need to inoculate our minds in addition to our bodies. (A mental vaccine, that is.)

Via Dawkins' Selfish Gene, we don't get measles, measles gets us. And in 2018-2019, it's doing a damn good job.


Here's a few newsbits on the subject:

Analyzing a Facebook-fueled anti-vaccination attack - 'It's not all about autism'
Mar 2019, phys.org

An analysis of Facebook profiles for people who posted anti-vaccination sentiments reveals four key subgroups that are interconnected by various themes. Credit: Elsevier
...anti-vaccination arguments are not "all about autism" and center on four distinct themes that can appeal to diverse audiences in four distinct subgroups:
  • "trust," which emphasized suspicion of the scientific community and concerns about personal liberty;
  • "alternatives," which focused on chemicals in vaccines and the use of homeopathic remedies instead of vaccination;
  • "safety," which focused on perceived risks and concerns about vaccination being immoral; and
  • "conspiracy," which suggested that the government and other entities hide information that this subgroup believes to be facts, including that the polio virus does not exist.

Facebook Takes Steps to Curb Sensational Health Claims

On Deceptive Language:
April Fools hoax stories could offer clues to help identify 'fake news'
Mar 2019, phys.org

"April Fools hoaxes are very useful because they provide us with a verifiable body of deceptive texts that give us an opportunity to find out about the linguistic techniques used when an author writes something fictitious disguised as a factual account," said Edward Dearden from Lancaster University, and lead-author of the research. "By looking at the language used in April Fools and comparing them with fake news stories we can get a better picture of the kinds of language used by authors of disinformation."

The researchers found that April fools hoax stories, when compared to genuine news:
  • Are generally shorter in length
  • Use more unique words
  • Use longer sentences
  • Are easier to read
  • Refer to vague events in the future
  • Contain more references to the present
  • Are less interested in past events
  • Contain fewer proper nouns
  • Use more first person pronouns

Fake news stories, when compared to genuine news:
  • Are shorter in length
  • Are easier to read
  • Use simplistic language
  • Contain fewer punctuation marks
  • Contain more proper nouns
  • Are generally less formal—use more first names such as 'Hillary' and contain more profanity and spelling mistakes
  • Contain very few dates
  • Use more first person pronouns

Study busts myths about gossip
May 2019, phys.org

"There is a surprising dearth of information about who gossips and how, given public interest and opinion on the subject," said Megan Robbins, an assistant psychology professor who led the study along with Alexander Karan, a graduate student in her lab.

If you're going to look at gossip like an academic, remove the value judgment we assign to the word. Gossip, in the academic's view, is not bad. It's simply talking about someone who isn't present. That talk could be positive, neutral, or negative.

"With that definition, it would be hard to think of a person who never gossips because that would mean the only time they mention someone is in their presence," Robbins said. "They could never talk about a celebrity unless the celebrity was present for the conversation; they would only mention any detail about anyone else if they are present."
  • Younger people engage in more negative gossip than older adults. There was no correlation with overall frequency of gossip when all three categories were combined.
  • About 14 percent of participants' conversations were gossip, or just under an hour in 16 waking hours
  • Almost three-fourths of gossip was neutral. Negative gossip (604 instances) was twice as prevalent as positive (376)
  • Gossip overwhelmingly was about an acquaintance and not a celebrity, with a comparison of 3,292 samples vs. 369
  • Extraverts gossip far more frequently than introverts, across all three types of gossip
  • Women gossip more than men, but only in neutral, information-sharing, gossip
  • Poorer, less education people don't gossip more than wealthier, better-educated people.

So Fake


There's so much going on in the Fake sector that I just can't keep track; here's a few bits:

Author pulls software that used deep learning to virtually undress women
June 2019, Ars Technica

This is it. Deep learning, neural networks, generative adversarial networks, all that. We see now the world in the way it looked when the internet first started showing up in people's homes, but then all of the sudden, a phone could connect to the internet while you're walking down the street.

Deep learning is the robots doing things humans never thought a robot could do, and things we never even thought to ask for. It's absolute magic, and it's about to completely f--- our sh-- up.

Mona Lisa guest on TV? Researchers work out talking heads from photos, art
May 2019, phys.org

We can now extrapolate from photo to video. Is that what Mona Lisa really looked like? Does it really matter? It is astutely pointed out that unlike previous techniques, this one doesn't need 3-D modelling to make the leap.

And how?
"Lengthy meta-learning" that's how.

Facebook removes accounts from Russia, Iran for 'coordinated inauthentic behavior'
Mar 2019, Reuters

Has a nice ring to it. Reminds me of "Low-Credibility Information"

Anyway, the accounts were removed for their behavior and not their content. Let that be a lesson. Not sure if I see this as a good thing because it means that the screening algorithms are sophisticated enough to identify patterns of activity rather than simple vis/text content recognition, or it's a bad thing because it's getting harder and harder to get away with illicit activity on the web. Depends on which side you're on I guess.

Melbourne fake Chinese beggars scam busted by police

Last but not least; it wouldn't be a report on the state of the fake without some of the old masters showing up.

From the same people who brought you the fake zoo with a legit dog purported to be a lion, we now bring you -- fake homeless people!

They are literally shipped from China to Australia to look disheveled and beg for money. I refuse to believe it but in the article they're talking about them clearing a few hundred dollars a day. Fake homeless people. It's one thing when you shave your head and throw on a saffron robe to be a begging Buddhist, but to be a part of an international underground beggar syndicate where you don't shower for weeks and lie prostrate on the ground, that's dedication.

*Actually, the more I look into this, the less funny it becomes. It's way more common than it should be, and devolves into maiming kids to use as bait; few people can resist giving money to a crippled kid on the street.

On the Buddhist Beggar Syndicate and the geographic function of susceptibility:

"The men targeted out-of-towners, [Robert Hammond, executive director and co-founder of Friends of the High Line] said, adding that his office staff had a rule of thumb for watching the interactions: --Each second a visitor was willing to talk to one of the robed men was equal to 50 miles away from New York City that the person probably lived.-- New Yorkers would not give the men even a second’s worth of their time, Mr. Hammond added."

^Here we have a refined specimen. I can't tell you exactly what makes this jump out at me, but it screams "robot". Maybe it's a semibot, same difference, the purpose is to manipulate; there's something intentional about it. Maybe because people don't really comment on a message board in order to influence others, but to voice their opinion, and the two look pretty different.

NASA to open International Space Station to tourists from 2020

The International Space Station will open to tourists by 2020. I don't need to say much else beyond the headline here, except that in the article, they refer to tourists as astronauts. In other words, soon we can all be astronauts.

Lasers in Training


Shots fired:
"There is a sizzle as a white "I was here" message is burned off the grey stone by the 56-year old... ."

"The laser evaporates the graffiti, without damaging the stone underneath," Daniela Valentini, who heads up the Angels' team of cultural heritage restorers, told AFP as she pointed the fibre laser's beam at a scrawled signature.

The word graffiti comes from "sgraffito", which comes from "to scratch". It referred to the scratching away of residue to reveal the surface underneath. There's a great modern example of this where artists leave their mark by removing decades-deep layers of dirt on city walls. It's called "reverse graffiti", although it's more closely related to the original word than spraypainting a subway car. In fact, most of us are guilty of this kind of graffiti. "Wash Me" written on a dirty window anyone? Running your finger through beads of condensation on a wet window? 

Graffiti took a hard turn with the advent of aerosol spray paint. A revolutionary turn. Spray paint changed everything. It also made graffiti a lot harder to remove. Before, you removed the graffiti by cleaning the surface. It was, in a way, a public service, a nudge. Now we need powerful solvents and specially-engineered surfaces to keep it under control. Graffiti is now a costly nuisance for property owners (but not hip marketing hustlers, or millenial-hungry municipalities with a couple empty walls in their downtown.)

Blazing past the harsh chemical treatments of the past, we've now entered the new era of graffiti removal. It might seem like overkill to burn it off with a laser, but this technique does help to preserve the defaced surface, since it only takes off the very top layer of the graffiti and nothing else.

But, as all things go, as fire fights fire, we have to wonder how this could evolve. Let's imagine that graffiti artists start using lasers the way the way they did spraypaint in the 1970's; what would that mean?

Then again, let's not think too hard. GRL already showed us what lasers can do. So did the sticky LED throwies that shut down Boston for a minute after glowing pictures of Aqua Teen Hunger Force showed up all over the place.

I Am a Man


AKA Trees Are People Too

Lake Erie is now a person. "Environmental entity" to be specific. This is not the first time something like this has happened. There's also a river in New Zealand. The Amazon River as well.

It's interesting to see this happen as we approach a time when inanimate robots and synthetic biology alike are questioning our definitions of life, sentience and morality towards the "other".

Also, let's not forget that in Japan, Shintoism/Animism reveres all things, even mountains, as having a spirit. Even words have a spirit; What does that even mean!
