Someone tosses a coin ten times; it comes up heads every time. What's the probability it comes up heads on the next toss? (Pretty darn high—part of @nntaleb's work is unprogramming you from your high-school rules of thumb.) Now consider the (related) Gambler's fallacy...

 In this case, it's a theory about compensation: the worse one's luck is, the more likely it is to see a reversal. On the surface, it's irrational. The more bad luck you have, the more you accumulate evidence that the system is rigged.
But there's also an anthropic component. If the luck is bad enough, it starts to become inconsistent with your survival. You've accumulated evidence for correlations in the environment, but these correlations (may be) inconsistent with (people like you) being in this environment.
An example. You're in a city where everyone takes public transport. You encounter a string of bad delays. It's reasonable to conclude they'll end—otherwise people wouldn't take public transport. It's unlikely that you happened to show up right when the network collapses.
Of course, that's a bad heuristic in a casino, which relies on a constant influx of losers. But in other environments, particularly with persistent populations and no evidence for sudden changes in the underlying laws, it makes sense.
Another example: the three-card monte scam in a big city. You meet some guys on the corner, who convince you to go in on the game. You win, a few times. The more you win, the more you ought to be convinced that your luck will turn. Otherwise, how are these guys there?
(In this case, the anthropic reasoning concerns the scamsters—it's unlikely that you showed up right when their operation starts to fall apart.)
The general principle, which again is due to @nntaleb, is a new kind of failure. The "IYI", intellectual-yet-idiot. IMO, this is driven by standardized testing—we started to promote people on the basis of their ability to internalize fake-but-difficult-to-master rules...
In a previous cycle, the British ran their empire by fast-tracking twelve year olds who could master Latin grammar. The ambiguities of interpretation make this a much better idea than the SAT version, where one learns more abstract "grammars"—e.g., integration by parts.
Everything can be degraded, of course. When I give CMU students the coin-toss problem, it's usually unfamiliar enough that they're thrown back on a more complex, and life-integrated, form of reasoning. But ask that question enough, and tutors will arise to teach the solution...
...which negates the original value of the puzzle. (BTW, nearly all the students "get it", which bodes well for our future engineers.)
A final thought on this, before I get back to my real work. If you pose this kind of problem as a teacher, there's a second level to what's going on: your students are also modeling you! (and your class.)
i.e., they're asking themselves—is this a class where we're all living in la-la land, or is there some substance here, some connection to our own lived experience?
So, yes, I'm proud that most of my students get it. :)
This is lovely—yes! "I can't be the only idiot" summarizes why we keep waiting for the train with rising hope. https://t.co/s3d4aFg7Tv
You might also connect it to the bulk-vs-long-tail. "I'm not the only idiot" is true when there are repeated tests of the system of similar magnitude.
OK, truly one last thought. A scam is more likely to succeed if you're doing something new, but can convince people you've always been around, that this is "normal". Certainly psychologically obvious, but it's fun to look at it from the point of view of rational analysis.
(In the case where the scam operates by inducing the Concorde/sunk-cost fallacy—slowly extracting money from the person, who continues to believe in a final payoff.)

This is a pretty valiant attempt to defend the "Feminist Glaciology" article, which says conventional wisdom is wrong, and this is a solid piece of scholarship. I'll beg to differ, because I think Jeffery, here, is confusing scholarship with "saying things that seem right".


The article is, at heart, deeply weird, even essentialist. Here, for example, is the claim that proposing climate engineering is a "man" thing. Also a "man" thing: attempting to get distance from a topic, approaching it in a disinterested fashion.


Also a "man" thing—physical courage. (I guess, not quite: physical courage "co-constitutes" masculinist glaciology along with nationalism and colonialism.)


There's criticism of a New York Times article that talks about glaciology adventures, which makes a similar point.


At the heart of this chunk is the claim that glaciology excludes women because of a narrative of scientific objectivity and physical adventure. This is a strong claim! It's not enough to say, hey, sure, sounds good. Is it true?

So—probability. Do we really need it? This has been on my mind since 2017, when I finally sat down to think through quantum theory. (/n)

One thing that’s always struck me is how *late* probability theory came in intellectual history. We had integral calculus before we had probability. And probability is insanely simple, mathematically!

I’m tempted to say that probability theory is not, in fact, Lindy. Frequentist probability is (for all the usual reasons) best understood as a heuristic. Bayesian interpretations, by contrast, take the remarkable step of tying it to mental states.

You have to work very hard to convince yourself that beliefs really are “degrees of belief in sets of events” (or whatever). It’s not natural—and I won’t rehearse the whole story about rational choice and decision theory...

So with those critiques in the back of my mind, when I read David Wallace’s decision-theoretic account of the Born Rule I was rather primed to say, hey, so what? Meaning...

So, today, for the first time in 25 (!) years of Apple, I downgraded. From the 2016 MacBook Pro to my 2013, which I had kept in a drawer...


It was pretty simple to do—Apple Time Machine backups let me do it with one click.

That first tweet captures, in two pictures, how badly Apple has “lost the plot” (to quote @wylieprof). On the right is the Apple MagSafe adapter, from 2013. On the left, what I had “upgraded” to.

Thanks, Apple! I really was nostalgic for worrying about yanking my computer off the table.

Oh and I really appreciated not knowing if my computer was charging. What was great was the little whoop sound you used, so that the speaker before me could be informed I was charging my laptop.

On Bayesianism, the Many Worlds Interpretation, and personal identity.

Some thoughts worked out in a letter to a friend, which is the kind of thing you do when off Twitter for a glorious week. (🧵)

“Chance is ignorance”—the Bayesian story; all probabilities represent states of mind, not states of the world. One *could* put (some) chances “in the world”, but let’s take Occam’s Razor seriously...

That the probability of a fair coin coming up heads is 50% simply means that marginalizing (tracing, as the physicists say) over the hidden facts leaves you, nearly, maximally ignorant of the outcome.

Quantum uncertainty (access below!) poses an apparent challenge to this story. There seems to be nothing to be ignorant about when it comes to (say) electron spin—there is nothing “inside” the

The electron is a simple object, in other words. So where does the uncertainty come from? One could follow David Wallace’s wonderful interpretation in terms of chaotic dynamics and decoherence, but let’s see if we can take another route...

One thing that goes unremarked about Wikipedia: the vast majority of the content was written over 12 years ago—which means (given turnover) that the editors dominant today were not directly involved in that creation.

Put another way, the editors who built the dominant nodes in this network...


...have little overlap with the ones who made this much more recent managerial flowchart.


Internet time runs at hundred-fold speed—the difference between the people who painted what's in the Uffizi, and the people in charge of keeping those paintings from deteriorating. Very different tasks, and (one presumes) very personalities as well. @PaulSkallas?

1/ ETH reached 18-month low today and there is this narrative that the price of is dropping because ICOs are liquidating their treasuries. Well, it’s completely wrong. Let’s look at the data!

https://t.co/yG0vecC7VT


2/ The sum of ETH holdings of ICO treasuries is now a little over 3.57M ETH (3.5% of supply). In April, the treasuries held 4.65 million ETH (4.5% of supply) indicating that they likely liquidated (or moved) about 23% since then.

3/ Despite the decline in ETH price, the selloff hasn’t been as drastic as many analysts anticipated. In the past two months, treasuries of projects that held ICOs liquidated (or moved) 172,00 ETH, or ~4.6% of total holdings.

4/ The most aggressive sellers were Status, district0x and Tierion (in order), which sold (or moved) nearly 55,000 ETH combined since September 9. Out of the 57 companies I tracked, 50% didn’t touch any of the ETH in their treasuries.


5/ At least 11 ICOs currently have a smaller “market capitalization” than the amount that they hold in their ETH treasuries alone (see table below).

Election day in US; to skip the politics and get straight to the money, here's our quarterly update. How do gold, silver, and government fiat money compare with bitcoin's 21 million? #Bitcoin is the 10th largest money in the world, ex-gold & silver. This is update #10.


2/ Bitcoin's monetary system marches on its continuously-lowering coin emission; meanwhile, other world monetary systems' units inflate, either naturally (like gold & silver ounces), or via monopolistic privilege (like government fiat money "printing").

3/ What follows isn't a lesson in stimulus or bailouts, whatever the world faces. It's an attempt at painting the monetary landscape around the globe. The dollars, euros, and yen we're all familiar with, collectively, are worth $25 trillion. This is an exercise in perspective.

4/ As many know, the response from governments worldwide to Covid-19 has been drastic, so expect big moves. Also interestingly, central banks have been much slower to update their data these days.

5/ Gold & silver is base money of the past. Government fiat is base money today. It comprises both physical cash… and a digital cash component. Bitcoin may be base money of the future. Before we get to the charts, it's important to clarify a few common misconceptions in money.

This "bitcoin is better than gold" statement going around once more show that bitcoiners have no clue about monetary history and what the purpose of a monetary system is. A thread.

1- Metal standards were never inflexible; they could not in order to operate properly. Qty of metal was changed, usually lowered, to accommodate for changing economic conditions: price of metal, scarcity of coins, financial needs of economic units (state and private), etc.

2- The purpose of a monetary system is to make the rest of the economy go. It is there to accommodate financial needs. The more elastic one can design the supply, the better.
That doesn't mean that monetary creation & destruction shouldn't follow any rules & have no constraint.

3- Rules and constraint impose depend on economic system and evolve over time has we learn how to manage better the system. In a capitalist economy, the private sector is subject to the profitability constraint. We have learned from experience that this is not enough.

3 (ii) Financial stability requires a "hedge finance" constraint for most private agents: profitability should be judged on income gains, not capital gains.
In the government sector, the constraints are ressource availability and political constraints.

Story time. There will be a couple crypto wallet addresses at the end of this one.

You follow this account, you know that I straddle the terminator - one foot in light, one in shadow. Good-ish bad guys, bad-ish good guys, I've never belonged anywhere else.

Right before the election, I was shown some things. How it started, it was worth following. Caution was indicated. *extreme* caution.


Given the starting context, the amount of time, the volume of information, the veracity of the parts I can check without triggering suspicion ... it's real and I think there'd be some advantage to getting it all.

This is going to require some bare metal in a facility outside the U.S.

This is something that will stay up, maybe clear till the midterm election.

And it needs a significant amount of disk space, for unpacking and sorting and such.

Unlike #ETH and #BTC $ Algo uses delegated proof of stake (DPOS) #AlgorandandFriends


Under the DPOS mechanism, the community will empower a number of users the delegates to choose the next block. This is a mechanism that is used by blockchains such as EOS etc. $Algo

There is a fixed number of delegates & these delegates can be viewed as having centralized control. In the adipose blockchain, the delegates may own a tiny fraction of the total money in the system. Yet, the whole blockchain is secure. $Algo

The Algorand consensus mechanism is called pure proof of stake. And it operates on this simple principle. It makes cheating by a minority of the money impossible and cheating by the majority stupid. $Algo

$Algo developed a mechanism so that those with small stakes cannot cheat, those that have a large stake in the network won’t cheat. It will completely devalue their holdings & make no economic sense. As long as 2/3 of the majority are honest, the protocol will work just fine. $

THE NOTICEABLE SIGNS OBSERVED ON IMPENDING DEATH(मृत्यु के संकेत या चिन्ह)

As per Skanda Puran, Kartikeya had narrated to Muni Agastya about the signs of the coming death. This is as per this ancient scripture.


If one experiences the air coming out of right nostril continuously then it is observed that the person dies within three years. If the breathing is continuous towards upper side from both the nostrils, then the person can die within two three days.

If the breathing is through the mouth instead of the nostrils then the person may live only for two days. The person should take into coignance these signs of the occurance of any sudden death.

As per astrology when the Surya is in the 7th house and Chandrama is in its own house and the breathing is only through the right nostril then the danger exists. If you see a yellow black coloured figure who becomes invisible immediately then the life span is limited to 2 years.

If any person sneezes, passes urine, stool and semen all together he has only a year more to live. If a person sees blue coloured snakes flying in the sky then he has only six more months to live. If a person sees any thing opposite to its real self like colours

Thirumalai Murugan Kovil
#Panpoli
#TamilNaduTemples 🚩

Thirumalai Murugan Temple is located in Tenkasi district of Tamil Nadu. Muruga is worshipped as Thirumalai kumarasamy. Temple is situated near Kerala border and known to be where Shri Murugan gave darshan to Rishi Agasthiar


Devi is worshipped in the temple as Thirumalai Kaali amman

Sthala Puranam says that, there was a priest named Poovanbhattar of Thirumalai Kaali amman. Murugar appeared in a dream of the bhattar and said to find a Vigraham, lying in particular place which is of Thirumalaikumaran


Bhattar conveyed the news to the Pandalam Raja and they went to find out the vigraham. Surprisingly ants showed the way to find the Vigraham. Thus Murugan vigraham was found and Prathista was done here. There is a lake with pure water on the top of the hill


which is said to be created by Agasthiyar. It is believed that kannaki of
Chilapathikaram visited here before going to Kerala. Sapthamathrukkal also worshipped Murugan here. Kanthashashti Thiruvizha is very famous here.

Okay look - I didn’t grow up with comic books. But I read stacks of science fiction digests and I kit-bashed model cars into fantasy rods, and just tried to maintain a low profile until I could get out of the house. So you could say I’m a distant cousin of the comic book fan. /1

And sometimes one’s childhood passion follows them into adulthood, sometimes not, sometimes as an adult one finds a passion they never had as a child and embraces it. For me, that must include getting involved with a puppet show at the age of thirty. /2

So who’s to say whose passion’s legitimate and whose is bogus? Nobody. Someone might indict your passion but they have no ground to stand on and should be dismissed out of hand. /3

Maybe they’re envious that you have a passion, maybe they think that their passion is cooler than yours, or maybe they’re just insecure, who knows. Doesn’t matter. /4

What matters is that if something gives you joy, and in the process doesn’t hurt others, then by all means follow it. It’s how we explore our secret hopes, our shadow sides, our inner character. /5

Sharing one incident... After Modi's Trichy youth conference, the very next morning when police were clearing up their mini-control room, they found 5 strange boys who were roaming there with bags. When police enquired them "Sir, we are from Subramaniapuram in Trichy.

Whatever political meeting or conference is held in this ground, we come here on the same night or morning hours to collect the Liquor bottles to sell in the scrap shop for 50 paisa to 1 rupee per bottle and we used to earn Rs 200 to Rs 400 on each such event.

Even in the last DMK meeting the very next day we collected around 1500 bottles. But for Modi's BJP meeting, we could not find even a single bottle in the whole ground. We are coming around and around and not a single bottle in any corner of the G Corner ground in Trichy,

we are much disappointed, sir!". Police seem were stunned and pleasantly surprised. This is what Modi magic does in this nation. Modi is the one who can lead our nation and make everyone prosper with hardwork in right direction and proper approach.

This funny but interesting anecdote was published by a statewide local daily Dinamalar. I have just translated and posting it here for rest of the nation;

I doubt there are many outside of Norway that know that the Norwegian pop group A-ha was critical in the introduction of electric car incentives in Norway. I certainly didn't. Read on...


In 1989, two members of the group, Morten Harket and Magne Furuholmen were in Switzerland with environmentalist Frederic Hauge, when they came across a hobby-converted Fiat Panda. Stated range: 45 km. They snapped it up and imported it to Norway.

Photo: In Switzerland (Bellona)


On arrival in Norway, the regs didn't accommodate the registration of electric cars so it couldn't legally be driven on the road. Since it had a propane-fuelled heater, just like a motorhome, they registered it as a motorhome.

Moreover, in contrast to petrol cars, diesel cars paid registration fees based on how far they were driven, and our heroes thought this should also apply to electric cars. So the two-seater Swiss-converted Fiat Panda was registered as a diesel motorhome in Norway.

They managed (somehow) to avoid paying the one-off registration fee in 1990, and ever since then electric cars have been exempted this now-substantial fee.
