Show HN: Phofee – Photography social platform built with Svelte 5https://phofee.com/Hello everyone! For the past few months I have been working on Phofee, a social platform for sharing high quality photos.The goal: Make a website that allows users to easily upload, share, and discover photos without having to sacrifice quality or mangle their images.Phofee allows users to upload multiple images of varying aspect ratios. All sub images in a single post are displayed in a small photo gallery, so all your photos can be seen at a glance.One of Phofee's unique features is the automatic extraction of photo metadata. When a user uploads a photo, metadata such as Camera Model, Lens, Aperture, ISO, and shutter speed are displayed under your photo. This way, other photographers can gain better insight into your creation process and learn from it.For this project, I took privacy very seriously. - All metadata is deleted from user's photos before posting. - We store minimal user information. - We don't store user passwords (by using Google OAuth). - We don't use Google Analytics.Aug 18, 2025 1:18 PM

Show HN: I just built a tool to turn any photo into pixel arthttps://www.phototopixel.art/Hey everyone,I'm excited to share a brand new side project I just finished building: phototopixel.art. It's a simple web tool that automatically converts any photo you upload into pixel art.I've always been a fan of the aesthetic of pixel art, but manually creating it is a tedious process. After trying out some existing tools and not being fully satisfied with the results, I decided to build my own. My goal was to create a fast and easy-to-use solution that consistently produces great-looking pixel art.Behind the Scenes The core of the tool uses a combination of color quantization and pixelation algorithms. When you upload a photo, the system analyzes its color data and reduces it to a limited palette, while simultaneously creating the iconic blocky look.One of the biggest challenges was fine-tuning the balance between preserving key details and achieving a genuine pixel art feel. I experimented a lot with the algorithm to find the sweet spot, allowing users to choose different settingAug 14, 2025 4:13 AM

Show HN: Generative Graphics LLM Benchmarkhttps://www.ggbench.com/I’ve been obsessed with code-driven graphics since my first ellipse() in Processing. There’s something magical about watching a few lines of code bloom into motion—clean, crisp, and totally reproducible. With GGBench, I’m turning that obsession into a public benchmark for AI-generated graphics.GGBench is a benchmarking platform to compare graphics produced by AI—especially code that renders visuals (still and animated). You vote on side-by-side outputs, and we rank models with an ELO system (the same concept chess uses). It’s simple, transparent, and designed to push the whole field forward.Why this benchmark needs to exist Most LLMs are fantastic at writing code, but they’re basically flying blind: they can’t actually see what they produce. They output p5.js or Three.js scripts and call it a day. Whether that code renders beautifully—or at all—has been tricky to evaluate at scale.Meanwhile, video diffusion models chew through compute to produce every pixel of every frame.

Show HN: Modos Developer Kit Live on Crowd Supplyhttps://www.crowdsupply.com/modos-tech/modos-paper-monitorToday, we’re launching our first product on Crowd Supply: a fast, open-hardware dev kit for driving e-ink displays.It supports 75Hz refresh, both color and monochrome panels, and more.This all started with a post on Hacker News about building an e-ink laptop. That post led to conversations with makers, minimalists, and others exploring how e-ink could fit into daily life, or help with personal health challenges. From those conversations came a community, which grew into a project, became a company, and brought us to today’s launch.We bootstrapped from the beginning, pushing through COVID shutdowns, chip shortages, shipping delays, and adapting to every new challenge along the way.We haven’t built the e-ink laptop yet, but we’ve built a foundation for creating high-performance e-ink devices.We’re sharing our small contribution today in hopes that it helps make e-ink more open and accessible.Thanks for being part of the journey.Aug 4, 2025 5:16 PM

Airbnb has locked payment on my account for 8 weeks and still no follow-up emailhttps://news.ycombinator.com/item?id=44424041A little before mid-May I opened Airbnb, as I’ve done hundreds of times over the past decade, to secure a house for an important summer event with friends. I clicked “Book,” waited for the familiar animation… and the payment failed.No big deal, I thought. I switched to another card. Same red banner. I tried my balance of gift credits. No luck. Over the next hour I repeated the ritual from three different devices—laptop, phone, even an old tablet—using cards issued while living and working all around Europe, both Americas, the Middle East. Every attempt ended the same way: an error, no explanation.For the first time in ten years of globe-trotting stays—rooftops in Lisbon, cabins in Patagonia, canal apartments in Amsterdam, lofts in San Francisco, studios in Dubai—Airbnb slammed a door in my face.So began my long walk through support.The chat agent was polite and assured me a “specialist” would email me.

Startups, VC, angels world was alien to me....So here's how we started. We would ping strangers on LinkedIn & events that I joined. I even spent Indian Rupees 1L ($4900 in PPP terms) on paid events/niche trainings.I’ve never hesitated to spend on my Curiosity. It pays back in long run.We helped strangers without expectations. Still ppl won't respond... I wondered why? These people posted they needed help.But this pain paid back in long run. You learn this is how the world works.
