The most frustrating aspect of working in computational probability/statistics is that it's basically impossible to construct algorithms that actually return well-defined probabilistic quantities and this results in no end of chaos.

 At best algorithms can return approximations with quantifiable error, but to understand when approximations are useful you have to learn enough math to understand the exact result and how the algorithmic approximation relates to that exact result. Many do not do this.
More commonly programmers project the heuristics that prove successful in other computing problems -- pattern matching, type consistency, unit testing, relying on compiler errors, etc -- but these test only the algorithm and not the relevance of the algorithm to a stats problem.
Unaware of these subtleties many end up conceptually replacing the algorithm for the output being approximated, assuming that algorithmic properties are inherent and well-defined features of the underlying probabilistic/statistical system.
Needless to say this generalizes...poorly. Even worse: without formal knowledge of what is being approximated the poor generalization performance itself is easy to ignore and naive applications drift ever so steadily away from any well-defined mathematical objective.
At some point the algorithms drift too far and it becomes impossible to make any formal critique of the emergent heuristics. How can you criticize an algorithm when it's doing everything people believe it's supposed to be doing?
Of course statistical procedures and methodology in general follow the same pattern. Many methods that are abused today were at one point grounded in mathematical validation, only for those foundations to be gradually lost as the methods were taught less and less carefully.
All of this is to say that most math people going around critiquing heuristic methods and advocating for learning more irritating, burdensome math are not being exclusionary cynics: we're just trying to help ensure that contributions are, and will continue to be, constructive.
Probability and statistics is fundamentally difficult. Compromising the math by replacing subtle concepts with vaguely overlapping algorithms and heuristics leads only to superficial inclusion that typically does more harm than good.
In order to responsibly expand our communities we need recognize this challenge, respecting the math and consistently evaluating our current understandings while also working like hell to guide those starting their journey towards a meaningful destination.

1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."

3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital:

5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.

It's funny how so many people who claim to worship "democracy" also dismiss nationalism as selfish xenophobia. Democracy is absolutely meaningless without strong national sovereignty. Under globalism, citizens of any given state have little influence over how they are governed.

Nationalism isn't just mindless tribalism. People are correct to insist their government has a responsibility TO THEM that vastly outweighs any imagined responsibility to foreign governments they have absolutely no influence over, or foreign populations.

We've seen that point taken to absurd extremes by the Left during the Trump administration, with whack-job judges ruling that foreigners have rights that EXCEED those of American citizens, including absolute rights to enter the U.S. and influence its government.

And we're frequently told that some international elite "consensus" completely overrides our ability to make individual decisions - or even to petition our own government, or vote for representatives who disagree with whatever "the world" has supposedly decided.

All of that is the absolute negation of "democracy" in any form, including the dangerous mob rule and majoritarianism that the Left selectively advocates. (Notice they always have a list of things nobody gets to vote on anymore, no matter how strong the majority vote would be.)

I've been wanting to write this thread for a while. It has been inspired by hearing a common thought: why can't people just "listen"? If people just followed the rules, we wouldn't be in this mess. I think this is oversimplification of the problem with COVID: 1/

It is true, there are people who haven't been following guidelines (by definition that happened a LOT at Christmas/NYE in my region), but even before, we know transmission in private gatherings happens. 2/

These private gatherings are pictured to be big raucous parties, but in reality, even before lockdown, this is just people having dinner, watching TV, doing things we did before on a daily basis. These little ripples when added across the country make a big wave.. 3/

...and little can be done about this apart from positive messaging. You can't very well have police patrolling neighbourhoods across the country. 4/

Next thing is we keep hearing over and over and over, stay home. There are diminishing returns with this advice, but also, most people who can stay home ARE. So what's the issue? There are a HUGE # of people who can't stay home because they work in essential jobs 5/

women of twitter: raise your hand if you’ve ever discovered that a male colleague with the same (or less!) years of experience and same job title as you was actually making more money?

i’ll go first: 🙋🏽‍♀️

i’ll never forget the feelings i experience when i found this out. initially, i felt shock, followed immediately by self-loathing—it seemed like the company had gotten me “on the cheap” and it made me feel incredibly like i had been incredibly stupid to not negotiate for more.

that quickly evolved into rage: how did they think it was okay to meet his negotiation demands when he was hired but not think to look at the other people at the same level and wonder if their compensation should be raised to match his, too?

i had always thought that i had always been an excellent performer at every company and role that i’ve held, so finding this news out felt a bit humiliating; i had to fight feelings of self-doubt and push myself to remember that i am stellar and deserved better—i deserved equity.

this is the moment in my career where i fully realized that i had to be own fiercest advocate. that was the moment that i decided to never assume that the company would see your worth—instead, it was always going to be on me to MAKE them to see it, or to go somewhere that would.

Having spent 2020 telling covid denalists that they were overly optimistic about the pandemic, I now look forward to spending 2021 telling covid maximalists that they are overly pessimistic about the end of the pandemic.

Telling a denialist in May that we shouldn't open bars back up = telling a maximalist in February that we should open schools back up.

Look, folks, the math is straightforward. ~13% of Americans have been vaccinated as of this

And the 7 day average continues to rise; we're approach 2 million vaccine doses per day. Meaning that we'll double that ~13% much faster than the two months it took us to get there.


So it's entirely reasonable that absent any other intervention, we should expect to hit ~30% vaccinated by the end of March.

So friends here is the thread on the recommended pathway for new entrants in the stock market.

Here I will share what I believe are essentials for anybody who is interested in stock markets and the resources to learn them, its from my experience and by no means exhaustive..

First the very basic : The Dow theory, Everybody must have basic understanding of it and must learn to observe High Highs, Higher Lows, Lower Highs and Lowers lows on charts and their

Even those who are more inclined towards fundamental side can also benefit from Dow theory, as it can hint start & end of Bull/Bear runs thereby indication entry and exits.


Next basic is Wyckoff's Theory. It tells how accumulation and distribution happens with regularity and how the market actually

Dow theory is old but

Hello Dear Tweeples!

It’s Siddhars time of the week! Last week I shared story of Guru (Machamuni or Yogi Matsyendranath), this week I bring you information on his Shishya.

#Thread on Gorakanathar Siddhar.

@LostTemple7


His origin story is interesting, though I couldn’t verify it’s authenticity, so not sharing the story here. He’s shishya of Machamuni Siddhar and also learnt from Agasthiya Siddhar.

@HelloNNewman @RajiIndustani @Kishoreciyer1

Unlike other Siddhars, he is depicted as either with a Tiger or seated & wearing Tiger skin. While I couldn’t find any explanation for this. My interpretation is as follows:

Tiger is a predator that lurks around and attacks unexpectedly.


Our 5 indriyas and 5 vikitis also similar to Tiger, they lurk around and attacks our thoughts when we’re least expecting. Gorakkar is said to have mastered these aspects, thus to denote this, he shown with Tiger.

@Itishree001 @VarierSangitha @jananisampath

Gorakanathar or Gorakshnath (as he’s known in the Nath Sampraday) is celebrated Guru in both Northern and Southern part of India. He’s one of the NavNath in Nath Sampraday and also 18 Siddhars of Tamil tradition. During his life, he’s travelled Indian subcontinent extensively +

1/ Throughout my startup career, I’ve seen many founders have an aversion to sales. This is a mistake that can kill your startup.

2/ Sales is often viewed as either a saving grace or proof that the product isn’t good enough (because it should sell itself). Neither are ever true. Some common mistakes that result in...

3/ Mistake 1: Hire a sales rep before reaching product/market fit to get your initial batch of customers. This is a mistake because founders need to work through their MVP with early adopters to truly understand what it is they’re selling.

4/ Mistake 2: Reach product/market fit, need to scale, and rely entirely on self-serve. For enterprise products that require big commitments and internal shifts, almost no product is self-explanatory enough to sell itself.

5/ Mistake 3: Make a first sales hire who isn’t scrappy enough to help mold the sales process from scratch. Some salespeople are amazing at their jobs, but not cut out to establish the processes that others end up following. This skillset is what @rdedatta calls a “sales ninja”.

A #story from #Thiruvilayadal puranam-one of divine leelas of Bhagwan Shiva

#threadseries #Madurai

Story 16- it is about how Bhagwan Shiva explained the meaning of Vedas to the Rishis.

வேதத்துக்குப் பொருள் அருளிச் செய்த படலம்


Once there was a great deluge,everything in the world was destroyed.All lifeforms that existed got perished.Afterwards ,due to Bhagwan Shiva creation started.Then from Bhagwan Shiv ji's mouth-birth of 🕉 OM- Pranavam happened.From Pranavam,4 vedas appeared. Rishis learned them.

Many Rishis in Naimisharanya learned Vedas&recited them but they didn't understand the meaning&essence of Vedas. They were worried as they couldn't find any guru who can teach them the meaning of Vedas.That time,Rishi Arabhatar visited them.Rishis told him about need their worry.

Rishi Arabhatar told them that Bhagwan Shiva has given Vedas &he would be grateful enough to teach the meaning as well.But for that rishis have to rigorous penance at a sacred place.Also told them to go to Sundareswarar temple in Madurai to do tapas in front of Dakshinamurthy.

Assured them that Dakshinamurthy himself will come & teach them.Rishis proceeded to Madurai & started their tapas in front of Dakshinamurthy sannidhi for almost a year starting from Karthigai month pournami to next year Karthigai month pournami following all rituals..annadan

Mangottu Bhagavathi Temple
#Palakkad #Kerala
#keralatemples 🚩

Mangottu Bhagavathi Temple is situated in Athipotta near Alathur of palakkad district. Devi is kshipraprasadi here and grants relief to those who worship with full faith.
Mookken Chathen, situated on the Northern 👇


side of the temple, is guarding Devi here.
Story says that, once there lived a weaver named Kuttan who was a Devi Bhaktan. During one festival time Kuttan was so pleased by the Devi Vigraham that he requested her to come along with him. At that time wind blew heavily and Cloths


in Vigraham flew. Kuttan immediately decorated Devi with his cloth which stuck to Vigraham and returned to his village and with his Umbrella. Devi came with him in that Umbrella and stayed in his place. This place is Mangottu Bhagavathi temple now.
