A Nigerian fintech just lost ₦20 million to a fake webhook.
Attacker didn’t hack anything.
They just POSTed this to the endpoint:
{
"event": "transfer.success",
"amount": 500000,
"status": "success"
}
Backend credited the user. Zero money moved.
This is happening more in crypto payments too.
What every backend dev must do in 2026:
1. Verify webhook signature + IP + timestamp (not just event name).
2. Never credit on webhook alone always confirm on-chain + NIBSS.
3. Add rate limiting and replay attack protection.
4. Reconcile every stablecoin inflow against blockchain truth.
Crypto rails move fast. One lazy endpoint and you’re done.
Save this like your production depends on it.

I want to be rich. But not Lamborghini
or Rolex rich, I want to be rich enough to go to the gym at 3pm and nobody can tell me no. To tap the family in front of me at the supermarket and say, "It's on me," Rich enough that my future wife never has to worry about getting a job. Rich enough to show my children the world, not pictures of it. Rich enough to take my friends to dinner and say, "| got this", Rich enough that God uses me to help the people who are in need. That's my version of rich.

When we were growing up, we made plans with our friends. We wanted to be successful and we wanted our friends to be successful as well. But the reality is that our clock is different. We would not all be successful and even the ones that are successful, succeed at different times.
The beauty of friendship is that, if one of us succeed, we have a measure of protection to leverage on. I do not know what you people call friendship but a person that want friends must show himself friendly, and there are friends closer than a brother.
This idea of making it and suddenly blacklisting the people you used to call friends, is insane. If they were not good people, you would have cut them off before you made it. The only person changing here is you.
It would be a shame if my friends need help and they can't ask me. Why am I in their lives then? What is the point of being friends for 10, 15, 20 years and I can't come through for you. I come through for strangers. Why wouldn't I show up for my own? My friends know me and they trust me. In fact, I'm sure they know that God forbid they die, their kids education and welfare will be sorted as I would my own kids.
Making new friends is good. We connect and expand on the relationships we have as we grow in life. If you keep cutting off the people you used to know as soon as you climb up the ladder, why should the new friends and connections trust you? The higher you climb, the harder it is to trust. That is why people say it is lonely at the top. People are not stupid, they are vetting your character whether you know it or not.
I have friends I made from secondary school. I have close friends from university who are my brothers. I have friends from my time in the UK and we are very close. I've made friends from X whom I am close with. Current relationship does not erase past relationship. Your new friends have other friends. There is nothing happening in your life currently that warrants cutting off your friends just because you're doing better. If you're doing better, you have a responsibility to look after them and be kind to them. Your friends are the only people in this cold world who allow you to be yours and who can call you to order, while still having your back against all odds.
DO BETTER!!!

A PhD student at Oxford got caught submitting "AI-generated" work.
Except he hadn't used AI to write anything.
He used it to think.
Here's the workflow his advisor called "the most sophisticated research process I've seen in 20 years."
He starts every essay with a brutal diagnostic prompt.
Dumps his rough argument into Claude and asks: "What are the 3 weakest logical jumps in this reasoning? Where would a hostile examiner attack first?"
The AI doesn't write his essay. It destroys his draft.
Then he rebuilds.
But the next step is what separates him from every other student using ChatGPT or Claude to generate paragraphs.
He uploads the top 5 papers in his field and asks: "What claims in my argument contradict or oversimplify what these authors actually found?"
Most students cite papers they've skimmed. He cites papers he's been forced to genuinely understand.
The final move is almost unfair.
Before submitting, he pastes his conclusion and asks: "What would a philosopher of science say is missing from this argument? What assumptions am I making that I haven't defended?"
His essays come back with comments like "unusually rigorous" and "demonstrates rare critical depth."
He's not using AI to write.
He's using it to think harder than he could alone.
The tool hasn't changed. The workflow has.

You see that genuine smile, this is of a result of marrying a feminine virgin from a financially stable home.
He doesn't have to worry about any exes or how to out fuck any previous men before him.
He knows her womb is intact and doesn't have to worry about a damaged womb cause he married her a virgin.
She has no whoring digital footprint.
Bro is confidently sound and firm which is why he can post her countless times on the internet, and no man will come under his comment section to say:
"I don knack your babe before."
"Your babe remove belle for my guy that year.'
"I get your babe nudes and sex tape."
At the end of the day, his boldness, happiness and relaxation is that he married a woman with a clean past and luckily for him, she's not a Nigerian.
You can never conceive me there's not an internal joy that comes with marrying a feminine virgin from a financially stable home.
Whereas an average Nigerian man will settle for a non virgin who was raised from a poor home and come on social media to say "I won"
Settle for a non virgin at your own peril.

$800B plus in networth, and not happy.
Solomon also mentioned this in the bible, that the love of wealth often leads to dissatisfaction and unhappiness.
This is absolutely true, you can wait until you get there to understand, and one thing about wealth is that the wants are unending.
Something i noticed is that being close to God helps create a satisfactory spirit in you, when you give arms, it gives a huge relief and joy to your heart, when you make others smile, you gain some atom of happiness.
So if you’re rich, and not really happy; make out time to get close to God, and give charity (in person) to people who really need it.

Whoever said “money can’t buy happiness” really knew what they were talking about 😔
