Catch me there! I'll be present during the whole conference and I'm really looking forward to meeting you all 🥳

While creating my space engine with #golang, I made a discovery! COCONUTS-2: look at this BEAST 🤯 Caught my eyes because the planet's orbit is visible from SO far away. For fact: it takes the planet 1 MILLION years to orbit its star! 1:1 scale 👇 #buildinpublic

How I color exoplanets in my #golang space engine: • Small + cold = rocky/icy (blue-gray) • Small + hot = rocky (brown-orange) • Large + any temp = gas giant (pale colors) Temperature and radius reveal composition. Difference is subtile though! #buildinpublic #gamedev

The heart of orbital mechanics: Kepler's equation. *Real-time* positions! 121 lines of Go implementing 400-year-old math. Throwback when I compared my calculated planet positions with @NASA graphics. Look carefully: it's a match! 🥳 #buildinpublic #astronomy #physics #gamedev

Automatic system detection! The app now knows which star system you're looking at: their bounding box is simply the size of their largest orbit Pan to Alpha Centauri, HUD updates. Pan to TRAPPIST-1, HUD updates. Notice the "Current System" UI! #buildinpublic #golang #gamedev

Zoom range in my space engine: from 1e-11 (interstellar scale) to 100x (planet level). That's a 10 trillion:1 ratio. Rendering at every scale took some work: no rendering of items at a certain distance is a great start Stack: #golang + #Ebiten by @hajimehoshi 💥 #buildinpublic

This was the first moon in my space engine: Earth's Moon. A body orbiting a body that's orbiting another body. Nested orbital mechanics! This was the moment I knew the physics engine was working! #buildinpublic #gamedev #golang

Underestimated #gamedev challenge: camera systems 🎥 World position ≠ screen position. Today I added a function to handle all the coordinate transformations depending on the camera position. Old-school vibes: managing the whole camera system yourself! #buildinpublic #golang

Sometimes the best progress is invisible (and not fun). Simplified celestial body initialization, removed useless constructors, etc. Same functionality, less complexity. Necessary before going further. Refactoring is shipping! #buildinpublic #gamedev #golang

First real bug in my space engine: time wasn't updating correctly. Planets moved wrongly, depending on the frame rate. The fix: proper frame timing calculations. Classic trap in game dev: not all machines run the app at the same FPS 😅 #buildinpublic #golang #gamedev

Shoutout to NASA's Exoplanet Archive! Free access to: • 46,996 stellar hosts • 6,134 confirmed exoplanets • Orbital parameters, temperatures, radii Open data enables projects like the one I'm creating. Thank you, @NASA! 🥳 #buildinpublic #opendata #golang

Most underrated feature in my space engine: the parallax starfield. Did it first almost 20 years ago when creating a space shooter! Less than 90 LOC, just dots moving at different speeds. Transforms a flat 2D view into something infinite. Details matter. #buildinpublic #golang

Current stats for my 2D space engine in #golang: • 27 commits • Less than 2 weeks of work • ~1,500 lines of Go • 53,000+ celestial objects Building in public works it seems! #buildinpublic #gamedev

Tech stack for my 2D space engine: • Go • Ebiten, the 2D game engine • NASA Exoplanet Archive with free, comprehensive data • Achieved to avoid using LLM agents! Total dependencies: 3 Sometimes less is more. #buildinpublic #golang #gamedev

Couple weeks ago: "I want to build a 2D space engine" Today: • 8 planets with accurate orbits • 46,996 real star systems • 6,134 real exoplanets • Temperature-based star colors • Parallax starfield • Full HUD system What's stopping you from starting? #buildinpublic #gamedev

Exoplanets are now orbiting in real-time! ✨ Orbital periods calculated from actual @NASA data, once again (from exoplanetarchive.ipac.caltech.edu) See the exoplanets dance, and notice the time factor! The simulation is in GREAT shape! #buildinpublic #golang #gamedev

6,134 real exoplanets now loaded from @NASA. Each one linked to its host star. Colored by radius and temperature of course! You're not looking at made-up data: these are real discoveries, CONFIRMED exoplanets! 🪐 #buildinpublic #gamedev #golang

One of the BIGGEST update! Click a star 👉 Press G 👉 You're there. Exploring 47,000 systems is now actually feasible. Before, with just keyboard shortcuts, it became a nightmare 💀 Also some REAL support for mouse drag/wheel! #buildinpublic #golang #gamedev

Stars are now colored by their surface temperature. Hot stars 👉 blue Cool stars 👉 red Real astrophysics, not random colors: the Hertzsprung-Russell diagram in action! #buildinpublic #golang #gamedev

Just loaded 46,996 real stellar hosts from @NASA's database. My #golang solar system app can now render the entire known catalog of star systems. This changes everything. Got to hide planet labels when far enough and only display the system name! #buildinpublic #gamedev

Big refactor today. Moved from "list of planets" to "star systems" architecture. The app detects which star system you're exploring. Foundation for something bigger as you can guess ✨ (Notice the "Current system name" updating in the video!) #buildinpublic #golang #gamedev

Built a complete HUD system: • Zoom level • Time scale • Pause status • Keybind hints 200+ lines of organized UI code. Honestly, this was near-zero fun, but it was absolutely necessary at this point. #buildinpublic #gamedev #golang

It happened this morning! It was a really fun talk to give, already looking forward on presenting it again 😊

Added rings to Saturn and Uranus. 45 lines of sprite generation code. Some features are purely aesthetic. And that's okay. Yes it's ugly, but trust me: it was SO weird for these planets to have nothing at all! #buildinpublic #gamedev #golang

Made planet sizes match real astronomical proportions (finally!) in my #golang space engine. Jupiter is now properly massive. Earth is a tiny dot. Perspective on how small we really are, first run was... mind-blowing 🤯 Look by yourself! #buildinpublic #astronomy #gamedev

Optimized rendering in #golang! Before: calculating every frame After: cache + invalidate when needed Also reduced orbit position precision. It useless to be that accurate: my CPU shouldn't burn for that 😬 Heard about quadtrees 20 years ago, is it the next step? #buildinpublic #gamedev

Added a procedurally generated starfield with parallax scrolling in #golang ☄️✨ Background stars move slower than foreground objects. 88 LOC. Infinite depth perception. The universe feels WAY more alive now! What should I add next to make it feel more alive? #buildinpublic

Keyboard shortcuts update in my #Go 2D space engine: • L = toggle labels • O = toggle orbit paths • Arrow keys = pan camera • D/S = zoom in/out Already building muscle memory into the app 👀💪 #buildinpublic #ux #golang

Small feature, big impact. That's the kind of little things I love. Added labels to every celestial body. Pressing "L" toggle them on/off. Simple UX wins. Just like DX should always come first when it comes to code! #buildinpublic #gamedev #golang

Added real orbital mechanics to my #golang space engine! Planets now orbit the Sun using Kepler's equations. And the Moon orbits Earth of course + more realistic orbit sizes! Physics > static positions. 121 lines that changed pretty much everything. #buildinpublic #gamedev

Day 1 of #buildinpublic a space exploration engine from scratch in 2D. @golang + #Ebiten. No real game dev experience. First milestone: the 8 planets orbiting the sun with basic camera controls. It's just circles on a screen but we all start somewhere! #buildinpublic #golang

Crazy about the Reflection #API in #PHP? Hold onto your hats, because game-changing updates might be on the way: introducing isWritable() and isReadable() methods. I think these enhancements are very welcome, especially with asymmetric visibility. What’s your take on this RFC?

I’ve been struggling with some issue on #FrankenPHP. Asked #Claude Sonnet many times and it’s been looping over and over without success. Then I asked Opus and it found the issue one shot. It eats so many tokens but it’s a BEAST.

How are you still not using #FrankenPHP? That's free perf for everyone and every #PHP project! Just look at those benchmark results. Worst case scenario: same perf as Nginx/FPM, but with one less point of failure. What's holding you back?

Big news! @xai just unleashed their For You feed algorithm on GitHub, now open-source for all. Here's what I discovered diving into the repo 👇

20 billions times the World's RAM to store 100 qubits? Yep, you read that right! 🤯 Seems unbelievable, but it's a fact. Let me explain, with words that everybody can understand, in this new story 👉 medium.com/itnext/20-bi...
