A 21 de abril, este carril bici en París va ya por el millón y medio de ciclistas, 14.000 sólo hoy. Imagínate si toda esta gente hubiera elegido el coche para moverse, el puto atasco que habría montado. Pues nada, en Madrid no lo entienden.

[Matt Dancho (Business Science) @mdancho84]

Microsoft is making moves again.

A quiet little Python tool just shot to the top of GitHub’s trending charts.

100,000+ stars.

It’s called MarkItDown.

And it does something deceptively simple:

It turns almost any file into clean Markdown.

PDFs. Word docs. PowerPoints. Excel files. Images.

Drop a file in. Get structured Markdown out.

Sounds small.

It’s not.

Because one of the biggest bottlenecks in AI workflows — especially RAG systems — is getting messy, real-world documents into a format models can actually use.

And real-world documents are brutal.

PDFs are chaotic.
Word docs are full of hidden formatting junk.
PowerPoints are messy and often image-heavy.
Spreadsheets can be a nightmare to parse cleanly.

That’s where this gets interesting.

MarkItDown strips away the friction and gives you something LLM pipelines can actually work with.

In other words: less preprocessing, less pain, faster AI implementation.

Even better, this isn’t some random side project.

It’s an official Microsoft open-source tool.
Free. Commercially usable. Practical.

I tested it on a 200-page PDF.

A few seconds later, I had Markdown that was shockingly clean.

And that’s what big tech does at its best:

They take an annoying, universal problem that everyone has been duct-taping together…
and turn it into a simple standard.

That’s why this matters.

It’s not just a file conversion tool.

It’s infrastructure for the next wave of AI applications.

Hace casi ya 10 años que Rafael Uribe Noguera secuestró, abusó sexualmente y torturó hasta la muerte a la menor Yuliana Samboní, de 7 años, y la familia Uribe Noguera no ha reparado a la familia de la menor por su asesinato, como lo dictó un juez.

¡¿Por qué nadie habla de esto?!

Desde nuestra curul del @PartidoVerdeCoL Radicamos nuestro cuarto Proyecto de Acuerdo en el @ConcejoCali_ y ante @MovilidadCali denominado 𝗖𝗮𝗹𝗶 𝗲𝗻 𝗕𝗶𝗰𝗶, en aras de una ciudad que le de más espacio a las personas que a los carros, este es un proyecto construido y 𝙋𝙀𝘿𝘼𝙇𝙀𝘼𝘿𝙊 𝙀𝙉 𝙇𝘼𝙎 𝘾𝘼𝙇𝙇𝙀𝙎, de manera participativa, escuchando las experiencias de los colectivos y organizaciones de biciusuarios.

En #Cali 𝟱.𝟰% 𝗱𝗲 𝗹𝗼 𝗰𝗶𝘂𝗱𝗮𝗱𝗮𝗻𝗼𝘀 se mueven en 🚲, contamos con 𝟭𝟲𝟱 𝗸𝗺 𝗱𝗲 𝗰𝗶𝗰𝗹𝗼𝗿𝘂𝘁𝗮𝘀 𝗽𝗲𝗿𝗼 𝗺𝗲𝗻𝗼𝘀 𝗱𝗲𝗹 𝟰𝟬% 𝘀𝗼𝗻 𝗿𝗲𝗮𝗹𝗺𝗲𝗻𝘁𝗲 𝘀𝗲𝗴𝘂𝗿𝗮𝘀 𝘆 𝘀𝗲𝗴𝗿𝗲𝗴𝗮𝗱𝗮𝘀, además entre 15 y 25 ciclistas fallecen en las vías y 400 son lesionadas.
El modelo actual no es suficiente, por eso, le apostamos a que la #bicicleta sea reconocida como un 𝗺𝗲𝗱𝗶𝗼 𝗱𝗲 𝘁𝗿𝗮𝗻𝘀𝗽𝗼𝗿𝘁𝗲 𝗽𝗿𝗶𝗼𝗿𝗶𝘁𝗮𝗿𝗶𝗼, proponemos un proyecto que le dice 𝗦𝗜́ 𝗔 𝗟𝗔 𝗠𝗢𝗗𝗔𝗟𝗜𝗗𝗔𝗗 𝗦𝗢𝗦𝗧𝗘𝗡𝗜𝗕𝗟𝗘‼️🌻

Christopher Nolan admits he was inspired by Heat (1995) when making opening scene of The Dark Knight.

“We make it a city story. Heat was an influence because Mann understands how city can be a playground."

[The Vigilant Fox 🦊 @VigilantFox]

This teacher-turned-cognitive scientist shared a disturbing reality that left the room stunned.

“Our kids are LESS cognitively capable than we were at their age.”

Every previous generation outperformed its parents since we began recording in the late 1800s.

So, what happened?

Screens.

Dr. Jared Horvath explained:

“Gen Z is the first generation in modern history to underperform us on basically every cognitive measure we have, from basic attention to memory, to literacy, to numeracy, to executive functioning, to EVEN GENERAL IQ, even though they go to more school than we did.”

“So why? … The answer appears to be the tools we are using within schools to drive that learning (screens).”

“If you look at the data, once countries adopt digital technology widely in schools, performance goes down significantly, to the point where kids who use computers about five hours per day in school for learning purposes will score over two-thirds of a standard deviation LESS than kids who rarely or never touch tech at school. And that’s across 80 countries.”

But screens aren’t just decimating learning and making new generations less intelligent than the ones before them.

They’re doing something far worse. And when you take a closer look, it isn’t pretty. 🧵

Excited to share a new open-source project for the web-mapping and LiDAR community: maplibre-gl-lidar 🚀

With maplibre-gl-lidar, you can visualize large-scale LiDAR point clouds (LAS/LAZ, including COPC) directly in the browser using MapLibre GL JS. It supports point-cloud data stored locally or hosted on the web, and comes with an interactive GUI featuring customizable color schemes, classification legends, and point picking. It even works seamlessly inside Jupyter Notebooks.

Visualizing tens of millions of LiDAR points has never been this simple or fast, making it easy to build modern, lightweight, and fully interactive web-based LiDAR viewers.

Introducing the NASA Earthdata Plugin for QGIS!

NASA’s Earthdata archive hosts over 120 petabytes of satellite imagery and geospatial datasets, but accessing it has often required navigating complex web portals or writing code.

This new QGIS plugin changes that.

With the NASA Earthdata plugin, you can search, filter, preview, and download NASA datasets directly inside QGIS, no programming needed. It’s designed for anyone who wants fast, seamless access to NASA data within their existing GIS workflow.
