I don't think people have quite internalized *how* the US became the global leader in science and technology. It's partially a story of massive global talent migration.

And it's important to get this story right if we want to maintain

 Around 1900, the US was a bit of a scientific backwater when compared to Europe. Most of the exciting work was being done in Germany and Austria, especially.

Then came three enormous waves of academic and scientific talent to the US.
1) First came a group of Jewish scientists fleeing persecution.

In a massive own-goal, 1930s Nazi Germany dismissed ~15% of the physicists who made up a stunning 64% (!) of their physics citations.
The group who fleed to the US included intellectual superstars like Albert Einstein, Leo Szilard, John von Neumann, and Edward Teller who formed the backbone of the Manhattan Project.
In a pithy quote, Churchill’s military secretary Sir Ian Jacob is said to have remarked that the Allies won “because our German scientists were better than their German scientists.”
And this wasn't just a 1:1 transfer of talent, this new intellectual community pushed our domestic fields to become more productive and drew in new inventors.
2) After WWII there was a scramble between the US and the USSR for the remaining German scientists.

With the Cold War looming, the US brought over ~1,600 scientists through Operation Paperclip and the Soviets ~2,500 through Operation Osoaviakhim.
While the Americans brought fewer experts, they may have reached the brightest individuals. Included in the group was Wernher von Braun, who became the chief architect of the Saturn V rocket, and Adolf Busemann, who pioneered the concept of swept wings in aeronautics.
So the Manhattan and the Apollo projects, arguably the two greatest US techno-engineering feats of the 20th century, were the result of international scientific talent embedded in American scientific institutions.
3) A third wave of international talent recruitment could be identified in the waning years of the Cold War, as Soviet mathematicians and other academics began to look for an escape hatch.
American universities suddenly had their pick of top Soviet scientists and were bidding against each other for the brightest stars. https://t.co/O2vKx2zpTF
There was even a policy proposal at the time to subsidize employers of these scientists, in the hope that we could assimilate all this newly available global talent as rapidly as possible.
https://t.co/i0QMZeQaEa
The net effect of these three waves has been America’s consistent domination of international science and technology.

Using the Nobel Prize in Physics as a rough proxy, American scientists were involved in only three of the thirty prizes awarded between 1901 to 1933.
From 1934 to 2020, Americans have been involved in roughly two thirds!

And a huge share of these Nobel laureates have been either first- or second-generation immigrants from these three waves.
For a period after the fall of the Soviet Union, the US was effectively able to rest on its laurels.

We were unquestionably the best location for scientific research and so most inventors/promising academics wanted to come here.
The results were stunning! Look at this chart of immigrant inventors from 2000 - 2010 from @william_r_kerr.
But that's been starting to change. A combination of three things:
1) US immigration restrictions are growing more burdensome
2) There are better opportunities to contribute to cutting-edge research at home
3) Other countries are starting to grow more *proactive* in their attempts to poach international talent
https://t.co/EYSUhofYeO
There's a lot more we could be doing! Obviously, our immigration system is a big barrier...
But we should go beyond these reactive measures and take a more proactive approach to talent immigration.

Today we grudgingly let the most talented individuals apply to live here; we do not actively recruit them.
Today it is concerns about identifying and stopping threats that dominates the day-to-day work of DHS.

The main job of immigration agents seems to be “avoid letting in terrorists” rather than “maximize the growth potential of the United States.”
To correct for this, I suggest we need a new department/office that has the sole mandate of finding and recruiting the most talented inventors and scientists from around the world and inviting them to live in the US.
The strength of the US has always come from being the melting pot for the world's greatest scientists and technical practitioners.

We are the R&D lab for the world and we should act like it.

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.

Facebook may well be exceptionally nasty and it’s leadership particularly deceitful, but the whole enterprise is the natural conclusion to an ad-powered social network. Ever greater surveillance, hyper targeting, and engagement baiting is what the basic incentives demand.

Facebook cannot change course. The best they can do is keep dishing out empty apologies, commit to inconsequential adjustments to its algorithms, and spend more money on positive PR and negative projection. The rot is at the core of its very being.

This is why we, consumers and citizens, must make the change for Facebook. Antitrust forcing a breakup of the business, and consumer revolt driving #DeleteFacebook. Zuckerberg will never conclude that what he built has become such a net negative for the world on his own.

That’s why its so tragic that WhatsApp sold out to Facebook in particular. Finally a challenger that had a different model and different ethics. But few would say no to $19B, which is why we need antitrust enforcers to do it for them.

you know how Atari called the Jaguar as a "64bit system", because it had two 32bit CPUs? (or because it had a 64bit bus, but let's not worry about that)
we should apply that logic to the current generation of consoles.
So the Switch is a 256bit console. It's the Nintendo 256.

The Xbox Series X? terrible name.
Better call it the "Xbox 512 Blu-ray".
like the Jaguar CD, the Sega CD... the good old days when consoles had their media type in the name.

Boringly the PS5 is also a Playstation 512 Blu-ray, because both of them are using the same AMD Zen 2 CPU.

The Switch one is weeeird. It's built on an Nvidia Tegra X1, which is an 8 core 64-bit CPU, so that should be 512, right?

Well... no. Four of them can't be used. And later documentation doesn't even mention them.

it's some weird system where the system-on-a-chip has four Cortex-A57 cores and four Cortex-A53 cores but only the A57s are usable?

A thread about Eastshade's bike mechanic!

When I originally thought of putting a bicycling in Eastshade, I was pretty sure it wasn't going to work, for the simple fact that if it was easy, we'd see a lot more rideable bikes in games. Well, I was wrong. It took a mere week.


Its essentially a first person controller with extra momentum, resulting in the the movement direction lagging behind your look direction. Then I used the angle between the look and the movement to dictate camera "bank" and handle bar rotation, and voila! Game changing feature!


The look of the bike was harder than the movement. Bicycles are fairly modern, so it was tricky to fit it to the setting. I took some artistic liberties and settled on a penny farthing (but wooden), ignoring how impossible that would be to ride on the rugged terrain in Eastshade.

Surprisingly, the hardest part was sound. It didn't feel like riding a bike until I found the right sounds and how to trigger them. For a while I was stuck thinking too realistically. A penny farthing is fixed gear, pedaling sounds nothing like a regular modern bike.

Finally I abandoned realism and went with sounds normal people would associate with biking. We're all so used to modern bikes that we strongly associate the distinct ticking of a freewheel mechanism (think of the sound when you stop pedaling and coast on a modern bike).

I read two-and-a-half decades worth of Jeff Bezos’s Amazon shareholder letters.

It’s like a mini MBA.

Here I’ve pulled out a free guide for startups, investing, marketing, and “web3”🧵

(It’s a thread, not an ebook)


First, why the focus on web3?

It’s the mid 90’s. A 30-year-old Jeff Bezos is trying to raise money for Amazon. And investors are wondering,

“What’s this internet thing?”

Fast forward, the year is 2022, and folks today are wondering,

“What’s web3?”

Now, a little background…

In 1994, Bezos quit a well paying job to start Amazon.

It wasn’t an easy decision. But Bezos used his famous “regret minimization framework.”

In other words, he didn’t want to be 80 and regret not doing what he really wanted to do.

But what did he want?

Bezos didn’t set out to disrupt retail from the outset.

He simply wanted to come up with a business idea based on the internet and then let the internet grow around it while he kept working on it.

Today, that idea is worth $1.7 trillion and counting.

Moving on to the lessons…

Each year since 1997, Bezos has written an annual letter to Amazon shareholders.

These letters reveal a great deal of lessons and secrets behind his massive success.

So what are they?

The chorus of this song uses the shlokas taken from Sundarkand of Ramayana.

It is a series of Sanskrit shlokas recited by Jambavant to Hanuman to remind Him of his true potential.

1. धीवर प्रसार शौर्य भरा: The brave persevering one, your bravery is taking you forward.


2. उतसारा स्थिरा घम्भीरा: The one who is leaping higher and higher, who is firm and stable and seriously determined.

3. ुग्रामा असामा शौर्या भावा: He is strong, and without an equal in the ability/mentality to fight

4. रौद्रमा नवा भीतिर्मा: His anger will cause new fears in his foes.

5.विजिटरीपुरु धीरधारा, कलोथरा शिखरा कठोरा: This is a complex expression seen only in Indic language poetry. The poet is stating that Shivudu is experiencing the intensity of climbing a tough peak, and likening

it to the feeling in a hard battle, when you see your enemy defeated, and blood flowing like a rivulet. This is classical Veera rasa.

6.कुलकु थारथिलीथा गम्भीरा, जाया विराट वीरा: His rough body itself is like a sharp weapon (because he is determined to win). Hail this complete

hero of the world.

7.विलयगागनथाला भिकारा, गरज्जद्धरा गारा: The hero is destructive in the air/sky as well (because he can leap at an enemy from a great height). He can defeat the enemy (simply) with his fearsome roar of war.

Starting my 2nd thread on Sringeri Parampara. This will cover the Jagadgurus after Sri Vidyaranya to Sri Shivabhinava Nrisimha Bharati.

It is really very tough to match the brilliance and achievements of Vidyaranya. After whom came 15 - Chandrashekara Bharati [1386-1389].

The next Acharya was Nrisimha Bharati [1389-1408]. Harihara raya found a town for this Acharya - Narasimhapuram. Acharya helped the king by guiding him in political affairs. He also initiated the kind with mahamantras for spiritual development.

Subsequent Acharyas were
15-Puroshottama Bharati [1408 - 1448]
16-Shankara Bharati[1448 - 1455]
17-Chandrasekhara Bharati II [1455 - 1464]
18- Nrisimha Bharati II [1464 - 1479]
19-Puroshottama Bharati II [1479 - 1517]

20-Ramachandra Bharati [1517 - 1560]. Sadashiva Raya was emporer of Vijayanagara during this time.
21-Nrisimha Bharati III [1560 - 1573]
22-Nrisimha Bharati IV [1573 - 1576]
23-Nrisimha Bharati V [1576 - 1600]

24-Abhinava Nrisimha Bharati [1600-1623]. When he visited Malahanikareswara temple for first time he noticed there was no Vinayaka there so he took piece of turmeric and drew outline of Ganesha on a pillar and offered puja.

On 13 October Mtila as defacto overlord of the Boko Harram gang, allegedly carried out his penultimate cash-in-transit robbery. Sources say he sustained a head wound in a shootout with security guards. Some friends believe he was killed by a fellow

He died two days later, on 15 October, after allegedly being in a coma for more than a day. His funeral was a spectacle, held on Nyanga Sports fields on 24 October and attended by hundreds of people. Sources say it was made possible by Paarl businessman Lukhanyo "Spur" Mangena.
