Show HN: EarthToPixels – Turning real cities into explorable pixel art Hi HN! A few friends and I built EarthToPixels, a project that turns real-world cities into explorable pixel-art maps. We fine-tuned an open-source Qwen image model and built a pipeline that takes aerial imagery, generates pixel-art tiles, and keeps neighboring generations visually continuous so they can be stitched into a large map. We built the pipeline to work with arbitrary coordinates rather than a specific city. For the first complete render, we chose our hometown: João Pessoa, Brazil. You can explore it here: https://ift.tt/7WJpBib Would love to hear what you think, especially about the technical side. https://ift.tt/Xl9572J September 12, 2026 at 11:14PM

Show HN: Bodily Oddities When I was about 11 years old, my best friend and I were playing during recess at school, and I was carrying him around on my back, presumably pretending to be a multipart attack robot. All of a sudden, my heart started hurting, and I collapsed to my knees, and the robot was no more. Every time I inhaled, it would feel like a spike was being driven into my heart, and my breathing got completely shallow. I was sure I was done for, when all of a sudden, after an exhale, it disappeared. It wasn't until I was in my twenties that I learned this was called Precordial catch syndrome and it happens to most everyone. Every friend I've told about it was surprised, and also most knew the feeling. I collected a growing list of strange things bodies do ever since. And now finally I made it into a little page for others to see: https://ift.tt/qIBf4V2 It includes a form to tell me about new things, if you think they belong on the page.

Show HN: News observability site tracks coverage by party lean/distraction/etc. Heya HN! I'm helping launch this site which uses Qwen 3-32b to process thousands of news articles and analyze them by region, public interest, partisan lean, etc. We would love your feedback! https://pressaudit.org/ September 11, 2026 at 12:20AM
