This is how I imagine those bullies right now 😅

NodeOS

This repo contains first operating system powered by node.js and npm.

Is this the future of operating systems, or just a wildly cool experiment?

💥 EU slaps Google with €2.95B fine 💥

Brussels claims Google abused dominance in ad-tech, giving unfair preference to its own platforms (AdX & DFP) over rivals 🚫📊

Google allegedly made sure publishers and advertisers had to go through Google’s marketplace to get the best deals - squeezing out competition.

⚖️ This is one of the biggest antitrust penalties in EU history 💶

📊 Infographic Elements That Every Data Person Should Master 🚀

After years of working with data, I can tell you one thing:
👉 The chart ou choose is as important as the data itself.

Here’s your quick visual toolkit 👇

🔹 Timelines

* Sequential ⏩ great for processes
* Scaled ⏳ best for real dates/events

🔹 Circular Charts

* Donut 🍩 & Pie 🥧 for proportions
* Radial 🌌 for progress or cycles
* Venn 🎯 when you want to show overlaps

🔹 Creative Comparisons

* Bubble 🫧 & Area 🔵 for impact by size
* Dot Matrix 🔴 for colorful distributions
* Pictogram 👥 when storytelling matters most

🔹 Classic Must-Haves

* Bar 📊 & Histogram 📏 (clear, reliable)
* Line 📈 for trends
* Area 🌊 & Stacked Area for the “big picture”

🔹 Advanced Tricks

* Stacked Bar 🏗 when categories add up
* Span 📐 for ranges
* Arc 🌈 for relationships

💡 Pro tip from experience:
If your audience doesn’t “get it” in 3 seconds, change the chart. The best visualizations speak louder than numbers
