A gun in the hand of a soldier and same gun in the hand of a robber ideally serve different purposes.

It is dangerous and detrimental empowering the morally bereft

Education must encompass orienting towards pro human, pro life values

[Alex Onyia @winexviv]

There is no country on earth where a child will be sent to prison because they scored an F in an exam.

But every day, people lose their freedom, destroy their futures, or even lose their lives because of poor character, lack of discipline, greed, dishonesty, or violence.

Yet many parents panic over grades and ignore character.

If your child leaves school with integrity, discipline, empathy, resilience, and the ability to do the right thing even when nobody is watching, you’ve already won.

Academics can open doors.

Character determines what happens after those doors open.

The greatest product of any school should not be straight A’s.

It should be responsible human beings.

What’s your view?

O desastre do Challenger visto de um helicóptero. Em 28 de janeiro de 1986, um helicóptero registrou de um ângulo “privilegiado” os 73 segundos finais do ônibus espacial Challenger, que levava sete tripulantes, entre eles Christa McAuliffe, a primeira professora escolhida para viajar ao espaço.

A investigação concluiu que o frio extremo comprometeu os anéis de vedação (O-rings) de um dos propulsores de combustível sólido, permitindo o vazamento de gases superaquecidos que provocaram a destruição da nave. Todos os astronautas morreram.

A tragédia levou a NASA a suspender os voos dos ônibus espaciais por quase três anos e a reformular seus protocolos de segurança e engenharia, tornando-se um dos episódios mais marcantes da história da exploração espacial.

My students sometimes ask why they should memorise things in the age of Google and LLMs. But internalised facts are your bullshit filters and your raw material for creative association. Facts outside your head are inert.

The goal of parenting is not raising an obedient child.

It is raising a child who can make good decisions when you are not in the room.

This girl earns about half a million naira a month. One time, I was supposed to give her 8k for something, but I sent 10k instead.

When we spoke later, she was genuinely thanking me for the extra 2k.

I laughed about it, but she was completely serious.

I really admire grateful people. For them, it isn’t even about the money; it’s about the thought. The fact that someone considered you worthy of spending their hard-earned money on.

[Millie Marconi @MillieMarconnni]

A Japanese engineer invented the QR code for one job, tracking car parts on a Toyota line, then his company chose to give the patent away for free, which is the only reason it ended up on every restaurant table on Earth.

His name is Masahiro Hara. The company was Denso Wave, a parts supplier owned by Toyota.

In 1992 the problem landed on his desk, and it was not glamorous. Workers on the factory floor were drowning.

Every car part had a barcode, but a barcode can only hold about twenty characters, so to track one component they had to stick five or ten barcodes on it.

A worker would stand there scanning a single part ten times in a row. Some of them were scanning close to a thousand barcodes a day. The job had stopped being about building cars and turned into pointing a scanner at stickers all day long.

And there was a second problem nobody upstairs cared about. This was a factory. Oil got on everything. A smudge of grease across a barcode and the whole thing became unreadable, and the line stopped.

Hara was asked to make the scanner faster. He looked at it for a while and realized the scanner was not the problem. The barcode itself was the ceiling. A line of black bars can only hold information going one direction, left to right.

He decided to build something that held information in two directions, up and down as well as across, so it could store hundreds of times more in the same little square.

Then came the part that sounds made up but is not.

Hara played Go on his lunch breaks, the old board game with black and white stones sitting on a grid. He was staring at the board one day and it clicked.

The grid of black and white stones was already a way to store information in two directions. That was the shape of his code.

But building the code was the easy half. The hard problem was speed, because the whole point was to be fast, and a scanner wastes most of its time just trying to figure out where the code is and which way it is turned.

The fix came to him on a train. He was looking out the window at buildings, and one building stood out from all the others because of its shape against the sky. That was the idea.

He put three little square targets in three corners of the code. The moment a scanner sees those three squares, it knows instantly where the code is and how it is rotated, even upside down, even at an angle.

Now here is the detail that shows how far he was willing to go. Those three corner squares only work if nothing else on the page looks like them.

If a magazine ad or a cardboard box happened to have the same black and white pattern nearby, the scanner would get confused and grab the wrong thing.

So Hara and his tiny two-person team went and surveyed printed material. Magazines. Flyers. Cardboard boxes. Piles of it, for days, reducing every picture down to its ratio of black to white area, hunting for the one ratio that almost never shows up in print anywhere. They found it. One to one to three to one to one.

That exact rhythm of black and white is baked into every corner square of every QR code on Earth, and it is there because it is the pattern the printed world almost never produces by accident.

Then he solved the oil.

He built the code so it carries a backup of its own information, spread mathematically across the whole square. You can tear off, smudge, or scratch out up to thirty percent of a QR code and it still scans perfectly, because the code rebuilds the missing piece from the copy it kept of itself.

A worker could get grease on a third of the label and the line would keep moving. This is the same math that lets a scratched CD still play and lets a spacecraft send data back across the solar system without asking to repeat itself.

He finished in 1994. He named it Quick Response, after what it does for the person using it, not after what it is.

And then Denso made the decision that actually mattered.

They held the patent. They could have charged a fee on every single scan, and given how many billions happen now, that would have made someone unimaginably rich.

Instead they announced they would not enforce their rights to collect royalties, and they published the specification openly so anyone could use it. Hara later said it was not even a big argument inside the company.

That one choice is the whole story. A code that costs nothing to use is a code everyone builds on. Airlines put it on tickets. Phone makers built readers into cameras.

Then a pandemic hit and the world needed a way to hand someone information without touching anything, and the free little square that a Toyota engineer built for greasy factory workers was suddenly on every menu, every payment, every door.

Hara still works there. He has said, more than once, that he never imagined it would spread this far, and that the part he is proudest of is that it got used to keep people safe.

The man built it to survive oil on a factory floor. It ended up surviving everything else too.

You have scanned his work a hundred times this year. Now you know whose it was.

B4 I got a dog three years ago, I read a book on how to raise one. The core idea was simple: positive reinforcement, and correction without frustration. I spent the next 14 months training that dog. I applied the same approach to my two boys, who were toddlers at the time.

A wife went viral for admitting she and her husband are mediocre. Average looking, not funny, no friends, mentally ill. And she can't explain why their marriage feels like a fairytale.

A psychologist in Seattle solved this exact puzzle in the 1990s.

John Gottman wired an apartment near the University of Washington with cameras and brought in 130 newlywed couples to just live in it. He tracked something he called bids: the tiny reaches for attention partners make all day. "Look at that bird." "Listen to this." A sigh that wants acknowledging.

Six years later, 17 couples had divorced. When his team went back to the tapes, the still-married couples had turned toward those bids 86% of the time. The divorced couples had managed 33%.

That one behavior predicted the outcome better than anything else in the data. Looks never entered the model. Humor never entered the model. Intelligence, money, status, shared hobbies: none of it showed up.

Now reread her post. "I can spend every minute of every day with this dude and not really get tired of it. We can get in the car and just drive for hours and talk."

Two people driving nowhere for hours are exchanging hundreds of bids and catching nearly all of them.

She graded the marriage on every trait that predicts nothing, and missed that they're elite at the one behavior that predicts almost everything.

Charlie Munger’s advice to ambitious people on how to “become a billionaire”:

[James Clear @JamesClear]

Learn to love the interruptions. Find the fun in the delay, the humor in the challenge, the pleasure in the daily commute.

A great deal of life is spent dealing with interruptions and waiting for the conditions to turn. We think, "If I can just get past this, then things will open up." But the interruption is not standing between you and your life. It is your life.

Yes, I prefer hassle-free days too. But you'll rarely find a situation that is all bad. There are little pockets of joy folded inside the annoyances we face. There is always fun to be had, if you go looking for it.

This is one of the arts of living. It's the art of enjoying the imperfect days. It's the art of making all the moments count.

@aakashgupta this is exactly why phones are so harmful in social spaces; they suck up attention and prevent you from even noticing others' bids
