Intern asked me yesterday: "How do you always know what to do?"
I looked him dead in the eye.
"I don't. I just know how to look like I do."
He laughed. Thought I was joking.
I pulled up my browser history from last Tuesday.
"How to configure VLAN on Cisco switch"
"What is VLAN"
"Cisco switch won't save config"
"Cisco switch blinking orange meaning"
Showed him a ticket from that same day where I "expertly resolved a critical network segmentation issue."
It was the same switch.
His face went pale.
"So you just... Google everything?"
"Not everything. Sometimes I ask ChatGPT."
He asked what he should focus on learning.
"Learn to sound confident when you have no idea what you're doing. The technical skills will follow."
He starts his senior role next month. I'm training him well.
@wojakcodes Boredom isn’t a lack of things to do, it’s a lack of curiosity. The world is overflowing with knowledge, strength, and skill waiting to be explored. Staying bored means ignoring life’s endless playground.
The immune system is powerful.
Sometimes, too powerful.
If it goes unchecked, it can turn on us -
attacking our own organs, tissues, even our blood.
That’s why the 2025 Nobel Prize in Medicine matters so much.
It honors three scientists who figured out how the body stops itself from self-destructing.
🧬 Mary Brunkow
🧪 Fred Ramsdell
🧫 Shimon Sakaguchi
Here’s the story :👇
Every day, your body fights off thousands of invaders - viruses, bacteria, fungi.
But the real magic? It knows not to attack you.
That precision is everything.
And for decades, scientists thought they knew how it worked:
Bad immune cells were weeded out early in the thymus (central tolerance). End of story.
Except… that wasn’t the whole story.
Sakaguchi’s bold idea (1995)
He challenged the dogma.
He found a new class of immune cells doing something unexpected:
➡️ They weren’t attacking.
➡️ They were protecting.
He called them regulatory T cells - the immune system’s peacekeepers.
They roam the body and tell other immune cells:
“Stand down. This is us. Don’t attack.”
It was a radical idea at the time. But he was right.
Brunkow & Ramsdell’s breakthrough (2001)
They were studying a mysterious mouse.
It had a single mutation - and developed devastating autoimmune disease.
They found the cause: a gene called Foxp3.
🧬 Foxp3 isn’t just any gene.
It’s the master switch that tells cells to become regulatory T cells - the same ones Sakaguchi discovered.
Mutate it in mice or humans… and the immune system spins out of control.
In kids, that mutation causes a rare and deadly disease: IPEX syndrome.
The missing link (2003)
Sakaguchi came back to close the loop.
He proved that Foxp3 is what powers the regulatory T cells - the body’s tolerance enforcers.
This confirmed the whole mechanism.
➡️ We don’t just delete dangerous immune cells early on.
➡️ We also deploy specialized cells to watch over the rest.
➡️ That’s how we avoid autoimmune chaos.
The impact? Massive.
Their discoveries opened an entire new field: peripheral immune tolerance.
We now have:
🔹 New approaches to treat autoimmune diseases
🔹 Promising advances in organ transplant tolerance
🔹 Immunotherapies that fine-tune the immune system to fight cancer - without turning on the body
Some of these are already in clinical trials.
This isn’t just a scientific triumph.
It’s a reminder that:
✅ Curiosity still drives paradigm shifts.
✅ Going against the mainstream can change everything.
✅ Basic science leads to better medicine.
And sometimes, three scientists working decades apart can quietly solve one of biology’s deepest mysteries.
👉 That’s worth a Nobel.
When you throw a ball at a wall, you can be sure it will bounce back at you.
You would be extremely surprised if the ball suddenly appeared on the other side of the wall. In quantum mechanics this type of phenomenon is called tunnelling and is exactly the type of phenomenon that has given it a reputation for being bizarre and unintuitive.
The 2025 #NobelPrize laureates in physics John Clarke, Michel H. Devoret and John M. Martinis, used a series of experiments to demonstrate that the bizarre properties of the quantum world can be made concrete in a system big enough to be held in the hand. Their superconducting electrical system could tunnel from one state to another, as if it were passing straight through a wall. They also showed that the system absorbed and emitted energy in doses of specific sizes, just as predicted by quantum mechanics.

I used to talk like this until I realized our leaders are only a reflection of our collective values.
It’s the people wasting their own time; politicians are only representatives of the people’s aspirations.
