1/ Amazon is famous for its writing culture:

• "Mock press releases / FAQs" for new product pitches
• "6-page memos" instead of Powerpoint

Two former Amazon execs wrote a book called "Working Backwards" detailing the philosophy.

Here are some insights 🧵

 2/ The "Working Backwards" playbook

Instead of creating a product then finding customers, Amazon asks "What does the customer need?" and works toward the product.

✅Customer need --> Create product
❌Create product --> Find customer
3/ Write a mock press release

To determine if the customer need makes biz sense, employees write a press release:

• What problem is the new product solving
• Why it's better than existing options

To persuade a customer, the document has to be jargon-free and tell a story.
4/ Press release forces big thinking

You don't write a press release for an incremental improvements.

Creating a product worthy of a press release means really solving a customer problem and going after markets with large TAMs.
5/ Include an FAQ in press release

Addressing every potential customer question can help identify hurdles to getting something to market...and also uncover opportunities.
6/ Why memos over Powerpoint?

Amazon famously has execs write 6-page narrative-driven memos instead of Powerpoint decks.

The practice began in 2004 when Jeff Bezos noticed nothing was being decided after 60-minute long meetings with his inner circle (AKA S-Team).
7/ Memos > Powerpoint #1: More info density

People read faster than people can talk meaning that -- for a 60 minute meeting -- reading a memo before discussing an issue conveys much more information (10x more per one of the book's authors).

Narratives are also more memorable.
8/ Memos > Powerpoint #2: Ideas > Charisma

In Powerpoint presentations, a great presenter can sell a bad idea. Conversely, a poor presenter may be unable to sell a great idea.

In a memo, the idea wins.
9/ Memos > Powerpoint #3: Better analysis

Powerpoint's hierarchical (and sequential) structure is not ideal to address complex issues.

Narrative-driven memos can be multi-causal and provide a 360-degree view on a topic.
10/ Memos > Powerpoint #4: Focusses a meeting

If every meeting participant spends the first 1/3rd of a 60-minute meeting reading, there is a huge transfer of information.

It's a forcing function to get everyone on the same page and makes the remaining 40-minutes high quality.
11/ Memos > Powerpoint #5: Shared understanding

Whether or not one agrees with everything in a memo, focussed reading of a document provides a shared knowledge base with which to begin discussions.

Further, someone can quickly "get up to speed" by reading past memos.
12/ Memos > Powerpoint #6: Decisions need narrative

Powerpoint and Excel are great at communicating data.

However, at the executive level, you are making complex decisions and leading. This requires a mastery of narrative (AKA memo writing) to persuade stakeholders.
13/ Writing is crucial to help a company scale

At 20 employees, Bezos could be in every meeting. At 1k+ employees, he needed a way to “inject his lens of thinking” into the organization.

An archive of writing helps encode the thinking across the company (e.g. Annual letters)
14/ If you enjoy business breakdowns (and dumb memes), def HIT THAT FOLLOW.

The Wall Street Bets due diligence on Wendy’s is gold.

◻️ The release of a new summer salad
◻️ The @Wendys Twitter account, which has mastered “meta pragmatic roasting” (which is effective with younger people)

Steve Jobs famously said innovation is "saying no to 1000 things" before you say yes.

For more than a decade, Apple has used Pablo Picasso's Bull to drive home the lesson.

Here's a breakdown 🧵


In Dec. 1945, Picasso created "The Bull", a series of 11 lithographs (stone prints).

With each successive print, a bull is simplified and abstracted. Picasso's goal was to find "spirit of the beast".

At Apple, employees are taught this philosophy.


Below are the 1st, 4th and last stone print.

The bull progresses from:
◻️a realistic drawing
◻️to a deconstructed image w/ the famous "abstract" style
◻️to lines outlining a shape

Through 11 iterations, Picasso simplified the image until it captured the "essence" of the bull.


Picasso said of the abstraction process:

"Two holes. That’s the symbol for the face, enough to evoke it without representing it. But isn’t it strange that it can be done through such simple means? Whatever is most abstract may perhaps be the summit of reality.”


Enter Apple University.

In 2008, Steve Jobs tapped the dean of Yale School of Management to create an internal training curriculum for Apple.

The program was meant to teach new employees Apple's culture and design philosophy (the teachings are rarely shared with the public).

A Netflix user will browse the app for 90 seconds and leave if they find nothing.

Thumbnail artwork is actually NFLX's most effective lever to influence a viewer's choice. A user will look at one for only 1.8 seconds, so NFLX spends huge to optimize them.

Here's a breakdown🧵


1/ Spoiler alert: humans are visual animals.

Our eyes move 3-4x per second to process information and we can analyze an image in as little as 13 milliseconds.


2/ In 2014, Netflix consumer research showed that thumbnail artwork:

◻️ is "the biggest influencer...to watch content"
◻️ is the focus of 82% of browsing time

A user looks at one for only 1.8 seconds. If they can't find Netflix content in 90 seconds, they'll leave the app.


3/ Consequently, Netflix uses an elaborate thumbnail selection process for each of its 200m+ users.

The process is called aestethic visual analysis (AVA), which starts by pulling all the frames from a video.

For reference: a 1hr episode of "Stranger Things" has 86k frames.


4/ In a process known as "Frame Annotation", each frame is tagged with metadata identifying key variables:

◻️ Saliency
◻️ Frame #
◻️ Brightness / Contrast
◻️ Nudity probability
◻️ Face / skin tone

“I spend too much at Starbucks” is a legendary meme.

It's also not an accident: the coffee retailer -- worth $120B -- uses many psychological hacks in its store and menu designs to get you to drop more cash.

Here are 11 of them 🧵


1/ Starbucks is all about positioning

The chain has higher prices vs competitors. But that's the point.

People typically assign higher value/quality to higher prices. Known as "irrational value assessment", this makes Starbucks an everyday luxury that people will pay for.


2/ Premium brand = premium customer base

By setting its prices higher, Starbucks attracts clientele that are relatively price insensitive.

Starbucks frequently raises its prices with little negative effect to its bottom line.


3/ "More than coffee"

Former Starbucks CEO Howard Schultz created the premium feel by emphasizing experience:

◻️Positioned SBUX as a "third place" (b/t home, work)
◻️Brought bean grinding in-store (for aroma)
◻️Banned auto espresso machines (it took away from the barista craft)


4/ Lighting and visual cues

The Starbucks operations is about "flow", efficiently moving people around the store+ getting them to spend.

To form lines, it directs people to well-lit areas (usually the merchandise, which provides the added benefit of nudging products for sale).

Our intuitions often leads us astray. A good reminder: study counterintuitive math and economic results.

Here are 9 of them 🧵

The Birthday Paradox

In a room of 23 people, there's a >50% chance that 2 people share the same birthday.

This type of probabilistic thinking does *not* come naturally to many people.


The Coastline Paradox

Fractal geometry is also confounding:

The coastline of a landmass does not have a well-defined measurement. As the unit of measurement gets smaller (eg. from KMs to cm), the length increases without limit.


Winner's Curse

In an auction, the winning bid will usually exceed the intrinsic worth of an item leading to a significant overpay (and negative net profit for the winner).


Braess's Paradox

Removing an extra road can make everyone's commute time faster.

Why? The existence of a "fast" road leads to congestion because everyone uses it. If you remove the shortcut, traffic flows better.

So I was talking to @gewt about Job: A Comedy of Justice and I came up with a theory that I think explains why Heinlein's late-period work is so kinda-terrible and why I still enjoy it so much


So Heinlein had always been very interesting in the short parts of his novels, like the little snippets inside chapters. He had a very fun writing style, and wrote some fun dialogue with fun characters, right?>
It probably comes from how much of his early stuff was short fiction

And I think what happened with a lot of his longer works is that he'd just start writing fun bits and hope it would end up going somewhere or having a bigger plot by the end. like eventually he'd figure out where this was going, then go back and rewrite it into a cohesive whole

and I'm sure he had editors that'd help this process. No editor would let you publish something as rambly and changing-gears-every-other-chapter as The Number Of The Beast, for example... unless you were God-King Of Science Fiction 1980s Robert Heinlein.

so basically I think what happened is that by the 80s (when he was in his seventies!!) he lost the drive to go back and rewrite and he was too Untouchable for editors to make him.

I've completely fallen down a well of reading crappy superhero comics. (virtually all superhero comics are crappy.)

it's a comfort food thing. takes me back to my ill spent youth.

read a bunch of Dan Slott's she hulk run, which is depressingly sexist, all things considered. (the old, there's something wrong with you if you're a powerful woman who enjoys being powerful trope.)

Gail Simone's Birds of Prey is pretty fun; character interactions are great but she's got trouble figuring out worthwhile plots. all the villains are pretty eh.

read some Bendis avengers and new avengers. he writes fun characters, but the crossover stuff is so omnipresent it's hard for him to develop any narrative cohesion.

David Baddiel is getting lots of coverage and feedback on his book which again focuses on so called 'left wing' antisemitism.

I will start by saying that I have seen antisemitic comments made by Labour members and some genuine cases.

However, I have huge concerns.


2/x

Let's look in detail at this article written in April 2019 in the @Guardian - and I will explain the concerns.

The areas highlighted guide you to believe this was all Labour - IT WASN'T.

It also occurred before 2015! Detail follows...

https://t.co/cK59FP83aG


3/x

So as you see the writer of this rather deceitful piece starts with

"THAT CHANGED IN SEPTEMBER 2015" 🙄

This was done to point the timeframe as Corbyn's leadership. Yet the article goes on to describe things that are not even related to Labour, which occurred in 2014.


4/x

So... What in fact the @Guardian writer is discussing here is this case - where a group of Neo-Nazi's spent months inflicting abuse on Jewish MP Luciana Berger

All the detail is in the Court Notes when Bonehill-Paine was sentenced by the judge.

https://t.co/wAyo6Yro5Q


5/x

The Justice sentencing remarks to Neo-Nazi explain the previous cases too. See the date 2014.

Yet the Guardian writer refers to this NON LABOUR case to effectively make her article a lie.

"Star of David" - this was Garron Helm another neo-Nazi..

You want to buy a house.

You take a loan from the bank.

The bank asks you, “what if you don’t pay back?”

You say, “take my home and sell it”.

(Thread)

That makes sense. The bank gives you a loan and in case you don’t pay, the bank will take over your house and sell it and recover its money.

That’s collateral.

Banks also lend money to big corporations. With them, banks don’t always have collateral.

So a loan where the bank has collateral is considered safer for the bank.

In the early 2000s, the banks in the USA were giving out loans to people for buying houses.

The economy had just recovered from the tech bubble in 2000 where many banks had given out loans to businesses that had shut down.

In that backdrop, the banks found giving home loans safer.

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

https://t.co/7QIx5CFdfJ


The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

Mr. Vijay Kedia built a net worth of over Rs. 800 crores.

But you probably never read past that headline.

So I binged hours of interviews to learn his investing principles and strategies.

Here are 20 lessons on investing from @VijayKedia1 Sir:

Collaborated with @AdityaTodmal


Before I start, a quick disclaimer, please don't ape his portfolio.

As the entry price, horizon and risk appetite would be far different than yours.

Rather lets draw inspiration and try to learn his stock picking skills.

Now let's DIVE IN👇

1/ Started off as a trader:

- Soon, beginner’s luck started to fade out and loses started to mount, to an extent where his mother was about to sell her ornaments.

- Although he was able to dodge the situation.

- This incident taught him the biggest lesson to have a stop-loss.

2/ Punjab Tractors:

- In 1990, he made his first investment by putting in his 10-years savings of Rs 35,000 in this stock, based on a news trigger that tractor industry will witness a turnaround.

- It worked and fetched him 4-5 times which he calls it as a fluke.


3/ He believes that an investor must possess three qualities:

i. Knowledge,
ii. Courage, and
iii. Patience.
