''Curiosity is the engine of achievement''

About Me

Hi, I'm Loris.

By day I wrangle data and write SQL queries. By night I'm lost in a book, a habit that's been with me since I was a kid. If you can't find me, I'm probably on the floor with my laptop. Yes, actually on the floor. Something about it helps me think. My friends call it weird. I call it productive eccentricity.

When I get deep into a problem, I tend to pace around and talk to myself like a human fidget spinner. That same energy comes out when I'm discussing books or tossing around ideas with open-minded people who don't mind the occasional philosophical tangent.

I'm a little shy at first, but once that melts away I'm the friend who checks in regularly and genuinely wants to know how you're doing. I'll even watch TV series with you, though I secretly believe books are better, after all, you can control the pace.

Lately I've been on a bit of a self-discovery journey. Like most people, I sometimes find myself wondering where I fit in and what unique perspective I can bring to the table. I don't have it all figured out (who does?), but I'm starting to see that understanding yourself is a lot like reading a great mystery: you're both the detective and the main character.

Solving Klotski Without Help

From manual solving to building an automated solver

I challenged myself to solve Klotski without any external help, spending hours exploring different strategies. The breakthrough came when I discovered a set-based approach that identifies key intermediate positions from which the puzzle becomes solvable. This insight led Daniele and me to build a complete solver: the script first explores all possible board states, then uses Dijkstra's algorithm working backwards from the goal state (where the 2×2 block reaches the exit) to find the optimal solution path. It was fascinating to see how a manual solving strategy could be formalized into an elegant algorithmic solution.

Corsica: The Other Mediterranean Jewel

Seven days discovering France's island paradise

Just returned from a week in Corsica and I'm convinced it's Sardinia's equally beautiful twin sister. The island offers everything you'd expect - stunning beaches, crystal-clear waters, and genuinely warm locals who made every interaction memorable. While the famous beaches like Palombaggia were predictably packed, the real magic happened during those spontaneous hikes that led to completely secluded coves. Sometimes the best discoveries come from simply walking away from the crowds.

A Weekend in Umbria

Discovering Perugia's tranquility and Assisi's spiritual beauty

Spent a wonderful weekend exploring the heart of Umbria with my girlfriend. Perugia charmed us with its peaceful medieval streets and tranquil atmosphere, while Assisi captivated us with its spiritual heritage and countless churches. The highlight was witnessing an incredible sunset that painted the entire sky in shades of red and orange - a natural spectacle we'll never forget.

A Weekend in Marburg

Visiting friends, exploring forests, and solving puzzles

Spent a wonderful weekend in Marburg, a charming small city near Frankfurt, visiting my best friend and another close friend. We explored the picturesque old town with its winding cobblestone streets and half-timbered houses, enjoyed a lovely brunch together, and took long walks through the surrounding forests. The highlight? When we got back, we decided to tackle Klotski together and ended up writing a Python script to solve it. There's something special about combining good company, beautiful scenery, and a shared puzzle-solving challenge.
