Links for Feb 2021: Hello World
https://amp.cnn.com/cnn/2021/02/19/health/what-is-simp-teen-slang-wellness/index.html I’ve finally gotten a third article in my collection of classic Gen Z journalism. For reference, here are the first two articles in my collection: https://www.theverge.com/2018/9/23/17882996/teens-electric-scooter-age-requirement-bird-lime and https://www.theatlantic.com/technology/archive/2019/06/why-teens-try-airdrop-you-memes-concerts/591064/. Every sentence in all of these articles is quotable so just read them all.
This is the first time I’ve been personally scared of AI now that it’s coming after my own grift: trollish thought experiments (click through to see all 10)
https://beta.nsf.gov/science-matters/scientists-break-through-wall-sleep-untapped-world-dreams “researchers achieve two-way communication with lucidly dreaming people” If this checks out, it could be one of the biggest science stories of the year.
A note on the physics section: I don’t read all the links claiming a revolutionary breakthrough. I’m posting them because I think it’s interesting that there seems to be a few dozen revolutionary breakthroughs in physics each month, plus eventually when we figure out which one of them was actually a breakthrough I’ll be able to point back at it and look prescient. I’ve put the links I actually find interesting in the beginning of the section.
https://arxiv.org/abs/2102.01522 Robin Hanson is out with a paper on “Grabby Aliens” - aliens that expand very quickly and take over whatever they can reach. Many of these ideas turned out to have been explored previously by S. Jay Olson. See https://www.overcomingbias.com/2021/02/hail-s-jay-olson.html

https://phys.org/news/2021-02-life-sustaining-planets.html “The method described in the paper provides more than a tenfold improvement over existing capabilities to directly observe exoplanets, Wagner said. Most studies on exoplanet imaging have looked in infrared wavelengths of less than 10 microns, stopping just short of the range of wavelengths where such planets shine the brightest, Wagner said.”

https://www.atlasobscura.com/places/immovable-ladder-church-holy-sepulchre “Arguments and violent clashes are not uncommon. In November 2008 the internet was flooded with videos of a fistfight between Armenian and Greek monks in one such dispute. A small section of the roof of the church is disputed between the Copts and Ethiopians. At least one Coptic monk at any given time sits there on a chair placed on a particular spot to express this claim. On a hot summer day he moved his chair some 20cm more into the shade. This was interpreted as a hostile act and violation of status quo. Eleven were hospitalized after a fight resulting from this provocation.”
”Some time in the first half of the 18th century, someone placed a ladder up against the wall of the church. No one is sure who he was, or more importantly, to which sect he belonged. The ladder remains there to this date. No one dares touch it, lest they disturb the status quo, and provoke the wrath of others.”

One is genuinely romantically interested (θ=2) while the other is simply being friendly (θ=1). Unfortunately, it is difficult to differentiate between the two in practice, because we cannot simply find out people’s true parameter values.”

At that point, according to Amir Siraj, a Harvard student who co-authored the paper with Professor Avi Loeb, "Jupiter acts as a kind of pinball machine."
The theory goes: Jupiter's gravity shot this incoming comet into an orbit that brought it very close to the sun, whose tidal forces caused the comet to break apart. Some of the comet's fragments entered Earth's orbit, and one slammed into the coast of Mexico.”

https://blogs.nvidia.com/blog/2021/02/18/geforce-cmp/ Nvidia is producing a separate line of GPUs for mining, and they’re limiting the hash rate of their main line of GPUs so it’s only useful for gamers, not miners. Interesting solution, although they should really scale up supply until they no longer have an issue with miners buying up too many GPUs and creating shortages for gamers.
