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?

🔥 It's probably common knowledge that Netlify makes deployment incredibly simple- you can connect a repo, pick a build command and 🚀

or just drop a folder in and you're done!

...but here are some other things you might not know about our deploys that are very special 🧵

Netlify has a concept of "atomic" deploys- which means a few things:

- You can preview a deploy when you've or someone else has just put in a PR

- You can roll back to ANY previous state, with one click, in milliseconds

- You always know what state your cache is in!

Netlify allows you to cancel a deploy- did you just put in a change, merge it and then realize you've made a terrible mistake? I've never done that. 😬 er...

No worries. You can cancel that deploy with the click of a button.

You can lock a deploy. Let's say you get everything ready for a big release, code review and tests are complete, it's all ready.

You can lock a deploy in a state to get ready for a major release, so that you know exactly what you're releasing and sleep well the night before. 😴

You can even get notifications about locked deploys via email, outgoing webhook, or Slack. Netlify can notify you when a deploy is either locked or unlocked.

Some of the things I've learned in more than 20 years in the tech industry.

You need to hear these.

🧵👇

Listen to more people who don't look like you, don't speak your language, and don't come from the same place you do.

We aren't doing this near enough.

Small habits compound.

No small improvement is too small.

Just aim for something new every day, and you'll be surprised at the end.

Take responsibility.

It doesn't really matter how you feel, I'm sure you could have done better.

Always keep the big picture in mind and never lose the forest for the trees.

Be the person that pulls everyone out of the rabbit holes.

A quick thread on intelligence analysis in the context of cyber threat intelligence. I see a number of CTI analysts get into near analysis paralysis phases for over thinking their assessments or over obsessing about if they might be wrong. (1/x)

Consider this scenario. A CTI analyst identifies new intrusions and based on the collection available and their expertise note that the victims are all banks. Their consumer wants to know when threats specifically target banks (not just that banks are victims).

The CTI analyst has, from their collection, at this time, and based on their expertise enough to make an activity group (leveraging the Diamond Model in this example) that meet's the requirement of their consumer. So what's the problem?

The CTI analyst begins to over think it. "What if I had more collection? Would my analysis change? I really don't *know* they aren't also targeting mining companies in Australia as I don't have collection there."

The analyst knows their analysis is going to be shared. Maybe even public. "What if another team or professional intelligence firm has more collection and ends up noting that it isn't banking specific at all. Banks are victims, not targets. Will my consumer distrust me later?"

South Korean carmaker Hyundai on Wednesday presented the first 7 hydrogen-powered trucks to customers in Switzerland, out of 50 such vehicles scheduled this year to bring zero-emission commercial vehicles to European roads


For long haul, proponents say hydrogen-powered trucks have an advantage over electric rivals as they have a greater range and require less charging times but their uptake and mass production has been slow because they are expensive

However, a McKinsey study in January said that once relative efficiencies of the power sources and lifetime costs of a truck are factored in, green hydrogen could reach cost parity with diesel by 2030

PARITY WITH DIESEL ???

Hyundai has been partnering with Swiss companies to build a value chain covering the production of green hydrogen from hydropower, hydrogen charging stations and the service and maintenance of the trucks

The customers, which include supermarket chain Migros, will be leasing the trucks from Hyundai Hydrogen Mobility HHM to transport goods around the country, backed by the new hydrogen infrastructure

Ever wondered how the JVM debugger 'Evaluate' feature works in IDEs? Long ago I thought that the Java debug interface (JDI) actually allows you to specify the expression and get back its value.

However, this is not quite possible: there's no Java language compiler inside the JVM. When the process is paused JDI allows you to read or write any variables and fields or even execute an existing method with given arguments. But nothing like addition or multiplication.

On the other hand, #IntelliJIDEA debugger allows you to evaluate even statements! You can write there `for`, `if`, `while`, `switch` - whatever. You can even declare local variables. So how this works?

The answer is simple: IDEA debugger has a built-in interpreter for Java! If you access an existing variable or a field, call a method or instantiate an object, it queries JDI. Otherwise, IDE itself does all the calculations.

The amusing thing is that debugger authors didn't bother to make it as strict as Java itself, so the language inside the interpreter is a much more permissive version of Java. For example, you don't need to initialize variables there! Default values like 0 are used automatically.

"Working software is the primary measure of progress" is an enabling constraint. Sometimes, managers use the phrase as a club to get people coding. Coding, however, is a necessary driver of creating software, but it's not the only thing you have to do. 1/5

Standing in front of a whiteboard and discussing design, creating and running tests, just staring out the window and thinking, are all necessary parts of the development process; but if you don't get that software into your customers hands, you've accomplished nothing. 2/5

Using working software (the result of the process) as your measure of progress, puts natural limits on the entire process, including the staring-out-the-window parts. It forces you to work small (thus the "constraint") enough to deliver frequently. 3/5

I'll add that sometimes, progress does have to slow down so that you can think things through. That's fine. That's natural overhead in the process. Incorporate it into your planning. 4/5

But, if the overhead overtakes valuable work (creating "working software"), then you need to take a long hard look at how you're doing things. 5/5

The vast majority of images are jpegs, which are internally 420 YUV, but they get converted to 32 bit RGB for use in apps. Using native YUV formats would save half the memory and rendering bandwidth, speed loading, and provide a tiny quality improvement. It would also be \

a good path to supporting better video codec still image formats and 10 bit components. You can do it today, but you need to do the color conversion manually in a shader, which can be a big ask for some devs. Defining a FMT_JPEG_YUV that does driver injection akin to the \

external image support on Android could make it much more of a drop-in. Even doing it the hard way seems like it would be worthwhile for web browsers today.

One segment I have been absolutely upbeat is IT/Tech. Tech has always been the hidden moat for many companies - AP/BFL to name a few. Tech is no longer a vertical in market. It has become horizontal that cuts across every single vertical.

Be it Pharma/API, Finance, Insurance, Manufacturing, Retail, CD, or any other segment, Tech is going to give you edge over peers.

The spend on IT/Tech is going to increase stupendously in coming 4/5 years to levels we haven't even imagined. The investment in tech is going to help big get even bigger and put very hard survival barriers to new entrants.

BFL/HDFC Life from Fin/Insurance segment have one of the best tech platforms. IndiaMart relies on customer data monetization, Dmart has a very small but extremely strong team of data scientists

Even Nestle has very strong data scientist pool, Asian Paints story is well knows to everyone now. Not investing in IT/Tech is going to be your biggest mistake in investing journey.

@RubinReport Your commentary on the dangers of silicon valley coming under the spell of wokeness and cancel culture is spot on. I know this to be true because in Bitcoin we have already lived through a similar culture war against crypto anarchists.

We experienced firsthand the tactics such groups use to eliminate ¨wrongspreak¨ from public debate. And as you rightly recognize, this exact thing is currently happening in society as a whole. And not surprisingly often by the exact same people.

For example, Jack Dorsey, investor in and honored by the BTC cult, is the same person responsible for the twitter bans of many people, including a lifelong ban for the former president of USA. BTC ideology and such policies may seem incompatible with each other, but it is not.

As we stood up against social engineering and the destruction of language in Bitcoin we have been demonitized and deplatformed. Evidence: Just read the whitepaper and see how BTC, what they tell you is Bitcoin, doesn´t even come close to it.

So, just like you, we have been busy building our own alternative platforms based on new incentive structures and the Own Your Data philosophy.

For example have a look at this excellent presentation on @twetchapp

NEW INTERVIEW: Former Chairman of Sony Entertainment on Nintendo's Everlasting Intellectual Property

'Mario is probably impervious to extinction'

Nintendo has 100 years of experience in gaming.

'They are the masters in this field'

'As a platform holder, our job is to create a wider audience, continually.'

'I think Nintendo really understands the game design maxims for a handheld platform and then how to leverage their very powerful IP vault in that medium.'

It seems Fortnite and Roblox is additive to the industry and not exactly zero-sum vs AAA games?

Been reading up a lot about these jabs, esp as I know they are going to be a condition of a return to normality

Was on a zoom call last evening with a testing company that had some fascinating evidence on protection etc.

I have more reading to do.

I do not want to be coerced into something I don't want, BUT i want normal back as soon as possible.

Basically i'm at the point in my isolation and thinking that I'll take whatever just so this bullshit can end.

That is a desperate mindset, but so is 12 months of being cut off from the world.

All i have is what goes round and round in my head.

There's no one else to help balance it.

So i'm in group 6, and my surgery are doing group 6 right now. And i am at the point i want to do it to get it DONE.

And also to study what happens. Because i have that kind of mind.

I remember Pandemrix.

But we live with risk every day.

I risk my life climbing walls with only a harness around my waist to catch me as i lean back and fall off

And rational risk assessment is at the heart of everything going wrong these last 12 months
