This book is not about catching more fraud.
It is about understanding when suspicion itself is legitimate — and when systems pretend to know more than they do.

Minerva — Minimal Context for Transactional Fraud Assessment examines how modern financial systems make decisions under extreme uncertainty, time pressure, and abstraction. Instead of offering formulas or frameworks, the book asks a deeper question: what can responsibly be known before money moves?

Written for readers who work with data, risk, payments, and automated decision-making, this book explores why more data does not necessarily lead to better judgment, why context cannot always be inferred, and why responsibility cannot be delegated to models operating in milliseconds.

If you are looking for checklists, scores, or promises of accuracy, this is not that book.
If you are willing to confront the limits of automation — and think more carefully about what we choose to decide — Minerva is an invitation to slow down, question assumptions, and rethink what defensible judgment really means.

This is not a guide to implementation. It is a discipline of thought.

Read it if you are ready to think more carefully than the systems you build.

While the Band Plays is a collection of short stories that transform the everyday into poetry. In a small mountain town, where the early mornings smell of coffee, camellias, and light rain, life pulsates silently—until the band begins to climb the hill. It is the band that weaves together all the stories: loves, fights, domestic scares, births, departures, kept secrets, discreet miracles, and memories that insist on remaining.

Each story is a window that opens onto an extraordinary moment hidden in the ordinary. Each character experiences a different dawn. And each reading reveals a new path up the same hill. This book can be read in order or randomly. In any direction, the stories converse with each other—like echoes that cross houses, streets, and generations.

With humor, lyricism, and a rare tenderness, While the Band Plays celebrates what makes life worthwhile: the detail, the gesture, what almost goes unnoticed. This book is for those who love deeply moving narratives, for those who recognize beauty in simplicity, and for those who know that sometimes an entire city can fit within a single night.

Upon closing the book, you might discover: nothing is small when experienced attentively.

This book is a curated collection of articles published throughout 2025 by DataS2, an independent research laboratory dedicated to understanding data as a way of thinking — not as a product or a promise of optimization.

Rather than offering tutorials, frameworks, or definitive answers, these texts document questions as they emerged in real time: questions about small data, decision-making under uncertainty, automation, ethics, system design, and the limits of scale. Each article reflects a moment of inquiry, shaped by practical constraints, technical trade-offs, and intellectual doubt.

Readers should approach this book not as a guide to implementation, but as an invitation to slow down and examine how data-driven decisions are framed, justified, and often misunderstood. The value of the book lies in its coherence over time. Taken together, the articles reveal a consistent way of reasoning — skeptical of hype, attentive to context, and cautious about delegating judgment to systems.

This book is for readers who are less interested in quick answers and more interested in how good questions are formed. For professionals, researchers, and decision-makers working with limited data, imperfect information, or complex systems, it offers a way to recognize familiar problems from a different angle.

Reading this book means engaging with uncertainty deliberately. Not to resolve it, but to understand where it comes from — and why that understanding matters.

Billions of years ago

When nothing existed in matter

Only the silence of the great nothingness.

Destiny met Chance.

From an impossible kiss

Antimatter saw the material.

From the glow of the elektro

In gold and silver

The universe came into being.

Regarding the case of sunset

The first clock turned.

Because before, I had nothing.

After the kiss...

Everything came together.

Which clock turned?

The world was made

The large hand pointed to the dust.

From the dust I arose

And the stardust flew away.

From the deep earth emerges a magical place,
Keflavik is what they call it.
Beautiful landscapes of a friendly people
Before the
North Pole.
Climb the coast
Verdant lands full of warm air
Feel the breeze of
Europe to the Southwest
Walk the land of ice to the north.

"Pane e circum"
That's how the Empire was.
Some men were chosen,
salt was sprinkled on their bodies, and
"Live to die and die to live."

Gladiators fought.
Cries of euphoria echoed from the people, and
in the Colosseum,
blood flowed for bread.

Make your day worthwhile.

Call those you love.

Listen to what people have to say,

for we receive the greatest teachings

from where there is the most silence.

Dedicate yourself more to what you enjoy,

while it still loves you.

Meditate on the mandacaru cactus.

Night falls and a flower blooms

On that night, nothing will be so fragrant.

From sunset until its reappearance,

it will nourish souls and hearts.

Dawn breaks and

the last petal falls to the ground.

A lesson must be learned:

No one is eternal, love while you can.

I don’t just want to write a sentence.
Why write a sentence,
when I can set a poem to music?
I want to write about things from the past,
while laughing at the first rays of the future sun.

Why write loose phrases,
when I envision them forming books?
I want to express my joy to the world,
but poems aren’t well-received...
when they speak the truth.

I want to express in writing
what I think
, and repeat in my heart:
“I did more than I could have imagined.”

I don’t want to just write a sentence.
Why write a sentence,
If I can write music’s and poems?
I want to write about things in the past,
While I laugh at the first rays of the future sun.

Why write loose sentences,
Once I think about them forming books?
I want to write my joy to the world
However poetry’s aren’t well accepted...
When it speaks the truth.

I want to say whit lyrics
What I think
And I say in the heart
“I did more than I could imagine”.

Many hearts are broken by something so simple.

The length of days spent away from loved ones.

“It’s impossible to love from a distance.”

Kilometers, that’s what prevents it.

It’s not the distance that matters, but how much we love each other.

Are there no relations with the East in the West?

Don’t emails travel through servers in the other world?

A car made here in the Southern Hemisphere, isn’t it used in the Northern Hemisphere?

Why is loving from afar impossible?

Because you’re afraid to try and to love,

I’ll answer.

I was a child.

I was joking,

I fell, but with my head held high I ran.

Into my mother’s arms.

In my youth,

Among the trees behind the house,

I loved it and was rejected.

But your arms were still in pain...

Heartache in a storm of great fury within me.

Today, old and tired, I am

Remembering your eyes

Always saying

“I love you, my dear son.”

I was walking down a path
The fine grass I cut my foot.
I crouched
I picked up a stone
I played in the water
And made....
Pugum, pugum, pugum.

The roads aren’t ready for our love yet.

Knowing this saddens me.

Because you, even from afar, seem to be by my side.

I would start the billionaire revolution for your sake.

I would hold him in my arms.

It should be protected.

Next to mine

Heart

The side from which he wouldn’t let him leave and which would throb strongly.

They haven’t built roads for our love yet.

But we’ve already walked that path.

Every day we fight against our monsters.

However, we are afraid of those who are not yet born.

Just look around and you’ll see that we’re all on the same train.

Get off slowly at the next station.

Review the changes you’ve already made.

It will suffice to see that the world is too big not to be enjoyed.

There is a path I don’t want to return from.

I chose to walk through it without looking back.

Instead of wasting time on the absurdities of history,

I’m groping my way through the darkness in order to compose my happiness.

The fact is, I will never be the same again.

I made your arms my home.

I took refuge in them as I fled.

I’m running away.

I want to disappear into the waters.

Going beyond the sea

And not to return.

I climbed the banana tree.

To pick a bunch of grapes.

Hail the King of the Quinces!

Who gave you these tomatoes?

We smell each other's scents,
we embrace tighter.
Mine is your waist,
mine is your hair.

Spin, spin, in the air the whirls,
with each step we find our fate .
Spin, spin, in the fragrances of the heights,
to the rhythms of Mindelo.

To the sound of the Bollero.
I want
you to dance.

Dance,
child.
singing...

Yesterday, in the mirror,

He insisted on talking about things that had already been forgotten.

Not through persistence, but through

Pride, pure pride.

It was late,

I walked through the streets,

Before I loved you.

My reflection faded away, oblivious.

Amidst the lost nights.

Forgotten in pain

From the beating of the heart, a cooing sound.

Mera megera dos sons esfalera

When looking at the IMEI

Forgotten, reflecting the mark of the sea.

Sitting beside me was my grandfather. Always humming melodies that danced in the air. The happy birds completed the chorus. And the chorus of ladies joined in the murmur.

He stopped for a moment. The wind sang at the foot of the mountain. Jarinu had never been so quiet. The bell rang two more times. My grandfather expired.

The procession didn’t have time to pass. He had looked at his family, his body at the sea. Nothing was possible but to go and pray.

She lies bent over for hours spinning. She weaves here. She mends there.

He made this machine his life. On this wheel he created his family. And the ticking of the needle stitched himself together.

How many times have I seen tears well up in your eyes, slowly turning into cufflinks? Perhaps the most beautiful ever sewn on.

Take out the thread. Focus on the eye of the needle. Close your left eye. Wet the end of the thread, but just the very tip. Zap!, the thread will pass through in one go. Soon the ticking will begin again.

In the patchwork quilts, the crocheted embroidery, the satin ribbons, the finishing touches on the garments, your heart will race with every beat.

She girds her hips with the ruler and her hands with pins. She goes to take the measurements. She binds her tears in the clothes so that they may clothe not only the king, but the vagabond as well.
