When we say that "an algorithm is biased" we usually mean, "biased people made an algorithm." This explains why so much machine learning prediction turns into phrenology.

1/

 Researchers with phrenological delusions ask machines to find statistical correlates of personalities or emotions, and machines dutifully provides them. It's high-stakes, machine-human collaborative apophenia, detecting patterns where none exist.

Regrettably, this junk science gets published in respected journals. In 2017, @nature published a study by Stanford's Michal Kosinski claiming that machine learning could detect the facial correlates of homosexuality, creating an alleged AI gaydar.

3/
Unsurprisingly, Kosinski's study spectacularly failed to replicate. But as is so often the case, the blockbuster finding gets all the press, the careful replication work that calls it into doubt is roundly ignored.

https://t.co/J4rd6nLA4n

4/
Kosinski hasn't given up on AI phrenology. His lab's latest paper (published by Nature...again!) claims that he can detect political affiliation from social media photos.

https://t.co/kNPJ4vOwEr

5/
Spoiler: he can't.

What his system is most likely detecting is certain conventions in poses and expressions that are used in different political subcultures. Resting Karen face, basically.

6/
Unfortunately, this claim is being credulously reported in the tech press as true, even as the writer notes that this ML system barely outperforms random chance.

Scientific racism has been with us for centuries. It's enjoying a renaissance today, driven in part by the neophrenologists of the ML world. They are the modern descendants of the caliper-wielding eugenicists of yore.

8/
To understand the genomic science that refutes all of this nonsense, you can read @AdamRutherford's brilliant, short, witty, vastly informative book HOW TO ARGUE WITH A RACIST. You'll be glad you did.

One of the most Monkey's Paw things about my life is my relationship to books. When I was a teenager, I read all the way through the school and public libraries, spent everything I had on books, and still couldn't get enough and dreamt of more.

1/


Today, as a reviewer, I have more books than I can possibly read, huge, teetering mountains of books that I'm desperate to read, far beyond my ability to ever get through them. Periodically, I declare "book bankruptcy," sweep away the backlog and start over.

2/

Even then, my eyes are bigger than my stomach: I keep back a few books that I can't bear to part with and promise myself I'll read them someday. Usually I don't, but I just did, and boy did I ever make the right call with @TheUniverse's BROAD

I have read a LOT of histories of computing, and I had a front row seat for a lot of the events depicted in this book - people I worked with, people I worked against - and yet I was surprised over and over again with details and perspectives I'd never encountered.

4/

For example, for some reason, my ninth grade computer science course included lengthy readings on ENIAC, Univac, the Mark I and the Mark II, but none of those mentioned that they were all programmed exclusively or primarily by women.

Inequality requires narrative stabilizers. When you have too little and someone else has more than they can possibly use, simple logic dictates that you should take what they have.

1/


The forbearance exercised by the many when it comes to the wealth of the few isn't down to guards or laws - rather, the laws and the guards are effective because of the STORY, the story of why this is fair, even inevitable.

2/

Think of the story of monarchy and its relationship to the Church: the Church affirms that the monarch (and the aristocracy) was chosen by God ("dieu et mon droit") and the monarchy reciprocates by giving the Church moral and economic power within the kingdom.

3/

Capitalism replaced the story of divine will with a story of a self-correcting complex system: humans are born and raised with a variety of aptitudes and tastes, and at any moment, historical exigencies dictate that some individuals are better suited than others to do well.

4/

When it's railroad time, there are people who were born to oversee the laying of track and the coordination of rail networks: markets find those people, allocate capital to them, and allow them to mobilize that capital to produce shared prosperity for all of us.

One of the arguments for permitting monopolies is that they are "efficient." That's the logic under which Universal was allowed to acquire Comcast and NBC - the "vertical integration" would make all three companies better and we'd all reap the benefit.

1/


It turns out that there are DISeconomies of scale, what Brandeis called "the curse of bigness" and really, the Universal-NBC-Comcast octopus is a poster child for that

Comcast has just informed its subscribers that they are at risk of losing access to "Bravo, CNBC, E!, Golf Channel, MSNBC, Olympic Channel, Oxygen, Syfy, Telemundo, Universal Kids, NBC Universo, USA Network and NBC Sports

That is, Comcast has warned its customers that Comcast might not license its channels to Comcast anymore.

This is a "carriage dispute" - a dispute over how much the cable operator will pay the broadcaster. It's a common dispute to have.

4/

But in this case, Comcast's dispute is over the accounting fiction of how much one division of a vertical monopolist will nominally charge another to access its products.

A couple days back, I wrote up my best understanding of what happened with /r/wallstreetbets and meme stocks like Gamestop, trying to show how all the different, seemingly contradictory takes on the underlying financial stuff could all be true.

https://t.co/xWzre4r0Yj

1/


In the days since, a new series of contradictory takes has emerged, these ones disputing the meaning of this bizarre financial spectacle, and likewise what response, if any is warranted as it unfurls.

2/

I think that all of these takes can also be true, and as with the trading itself, reconciling them requires that we widen the frame.

Let's start with Jimmy Carter.

3/

In 1978, Carter's IRS created the 401(k), a tax-sheltered account for people who wanted to gamble on stocks to fund their retirement.

That was a fringe proposition at best.

4/

The normal retirement system was a "defined benefits" pension where your employer guaranteed you a certain monthly percentage of your salary from retirement to death.

The vast majority of Americans wisely prefered a guaranteed payout to a tax-advantaged gambling account.

2022 is shaping up to be a bloodbath. The Trump census cooked the numbers to advantage Republicans, and GOP statehouses are poised to redistrict in ways that will hand potentially permanent minority rule to the GOP in Congress.

1/


There's a potential way out: #HR1, an omnibus bill of electoral reforms that would create durable, structural protections for voting rights and a level playing field for campaigning.

2/

To get a sense of how urgent the looming crisis is - and of how important HR1 is - listen to @ryangrim interviewing @schwarz and Rep @JohnSarbanes [D-MD] on this week's

In theory, HR1 could be blasted through - Dems control the Senate, Congress, and the White House, and the future of the party depends on it, but I'm far from confident that they'll find the discipline and political will to make it happen.

4/

The Democrats keep squandering their majorities and wasting opportunities to make real change - changes that are must-haves, not nice-to-haves; changes needed to head off existential threats to the nation itself.

So, I want to talk about how sexual harassment and fair pay are linked at Google (and beyond), because I think that's an angle that isn't being highlighted enough in the coverage of these walk-outs. I'm going to frame it largely around my personal experience there. Thread.

When I was sexually harassed by the director of the area I was working in, I was afraid to report it because I was worried that "getting him in trouble" would result in the subtle retaliation of missed leadership opportunities.

I wanted to continue working on the team I was on, because I'd gained a lot of very deep knowledge and expertise in that area, as well as reputation and camaraderie with the other folks working in that area. I didn't want to make the situation more "difficult."

To get promoted at Google, several need to happen: 1. you need opportunities for ownership and leadership above your current level (basically, opportunities to show you're working at the next level you're trying to get promoted to). The work you're "assigned" has a big impact.

2. You need glowing reviews from peers, *at or particularly above the level you're hoping to get promoted to.* Basically, you need people a lot more senior than you to say you're doing awesome work.

Here’s a SPAC thread covering some basics for new followers. I will pin this to my profile if you want to share to anyone interested in SPACs.

SPAC timelines consist of these stages:
IPO – SPAC raises cash and begins trading as a unit. The cash is placed in Trust.
Searching phase – After IPO, the SPAC management team looks for a company to merge with. This is typically 24 months but can be shorter depending on the SPAC

LOI/Rumor – A letter of intent is announced publicly or Bloomberg/Reuters etc. breaks news of a rumor that a SPAC is close to a deal with a target.

The LOI/rumor stage does not always happen, most go straight to a definitive agreement. Rumors should only be considered to have value if from a trusted news source, internet rumblings are pure speculation. During this stage, a deal can still fall apart and not be signed.

Definitive agreement (DA) – deal officially inked. The SPAC begins filing paperwork with the SEC to have the merger approved to take the target company public. This process typically takes 4+ months after the DA is announced.

Some people really benefit from hearing advice that everyone knows, for the same reason we keep schools open despite every subject in them having been taught before.

In that spirit, here's some quick Things Many People Find Too Obvious To Have Told You Already.

Your idea is not valuable, at all. All value is in the execution. You think you are an exception; you are not. You should not insist on an NDA to talk about it; nobody serious will engage in contract review over an idea, and this will mark you as clueless.

Technologists tend to severely underestimate the difficulty and expense of creating software, especially at companies which do not have fully staffed industry leading engineering teams ("because software is so easy there, amirite guys?")

Charge more. Charge more still. Go on.

The press is a lossy and biased compression of events in the actual world, and is singularly consumed with its own rituals, status games, and incentives. The news necessarily fails to capture almost everything which happened yesterday. What it says is important usually isn't.

Companies find it incredibly hard to reliably staff positions with hard-working generalists who operate autonomously and have high risk tolerances. This is not the modal employee, including at places which are justifiably proud of the skill/diligence/etc of their employees.

A long time ago I coded up a feature for SocialCoder which converts a link - any link - to a short URL. I use it all the time for sharing links to volunteer profiles and to volunteer opportunity listings.

The feature doesn't care what the link contains, it just hashes the URL, including any query params, and returns a shortened code.

More recently, around Christmas time, I added another feature where I can click a button to send a template notification to a charity that their new listing has been reviewed and published. I call it a next-steps email.

For the past few weeks, its all been working well. Its nice to keep automating things that previously were done by hand.

Fast forward to today.

A new opportunity listing is posted by a charity.

I review and publish it, tweet about it, then click a button to send the charity an emailed notification of next steps.

After getting good feedback on yesterday's thread on #routemobile I think it is logical to do a bit in-depth technical study. Place #twilio at center, keep #routemobile & #tanla at the periphery & see who is each placed.


This thread is inspired by one of the articles I read on the-ken about #postman API & how they are transforming & expediting software product delivery & consumption, leading to enhanced developer productivity.

We all know that #Twilio offers host of APIs that can be readily used for faster integration by anyone who wants to have communication capabilities. Before we move ahead, let's get a few things cleared out.

Can anyone build the programming capability to process payments or communication capabilities? Yes, but will they, the answer is NO. Companies prefer to consume APIs offered by likes of #Stripe #twilio #Shopify #razorpay etc.

This offers two benefits - faster time to market, of course that means no need to re-invent the wheel + not worrying of compliance around payment process or communication regulations. This makes entire ecosystem extremely agile

What Happened To Bhakt Prahlad after Hiranyakashipu Vadh
#Thread
Prahlada became the mighty king of the Asuras after Shri Narsimha killed Hiranyakashipu. Prahlada was even more powerful than his father, Hiranyakashipu ever was. He enjoyed the love and respect of his subjects.


By virtue of his good behaviour, Prahlada conquered the three worlds easily and Indra ran away from the Heavens. Indra then deceived Prahlada into giving him the power of his behaviour and Prahlada lost control of the three worlds.


Asuras grew angry at the Devas for taking advantage of their King's virtuous behaviour and invaded the heavens. The Devas, afraid of the Asuras, enlisted the help of human Kings such as Yayati, Raji and Kakutstha and defeated them.

Prahlada attacked the gods and defeated Indra in battle, forcing the King of the Gods to run for his life. Indra sought help of Lord Vishnu. Infused with his power, Indra defeated Prahlada. The latter understood that Vishnu was helping Indra in battle and he withdrew his forces.


Prahlada first gave his kingdom to Andhaka, but the latter was defeated by Shiva. So Prahlada gave it to his son Virochana and undertook a Tirtha Yatra.

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

#bharatmandir #navratri2021

Created by Maharshi Parasurama and also one among the 108 Shakthi Peethas in the world. The name Kanyakumari stands for Kanya(Virgin) and Kumari(girl).
Devi took this form to vanquish the demon Banasura
@GunduHuDuGa


Once, Banasura(grand son of Mahabali) obtained a boon from Shiva that he could be vanquished only by a virgin.
So, Devi took the form of a kumari and started meditating with the desire to marry Shiva at Suchindram.
Pleased Shiva fixed the midnight hour for marriage with Devi.


Devarshi Narada knew that the marriage would end the chance of killing Banasura. So, he assumed the form of a cock and crowed. Shiva returned back to Suchindram thinking that it was dawn.
Angered, Devi cursed that all food and articles meant for wedding turn into sand and shells


When Banasura heard about Devi’s beauty, he tried to take her by force. Devi, then, killed him and granted the wish of Devas to remain there always protecting them.
The murti of Devi stands with a rosary in hand. Her diamond nose-ring is said to be visible even from the sea.


Once an ancient mariner mistook it for a lighthouse and sailing towards it, his ship wrecked upon the Kanya Kumari rocks. In order to prevent such a tragedy from happening again, the eastern door of the shrine is opened only on five special occasions throughout the year.
