Help Galaxy Zoo: Tidal Tales Open Cosmic Storybookhttps://science.nasa.gov/get-involved/citizen-science/help-galaxy-zoo-tidal-tales-open-cosmic-storybook/Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks to deep, high-resolution images from the Euclid space telescope, an ESA (European Space Agency) mission with critical contributions from NASA, we can now see these delicate structures more clearly than ever before in unprecedented numbers.

Show HN: I built a Mac app that converts files when you rename themhttps://news.ycombinator.com/item?id=47340433Hi HN,I built Morpholder after repeatedly running into the same annoying workflow on macOS.Every time I needed to convert a file I had to open a converter, upload the file, download it again, and move it back to Finder. It always felt unnecessary when I already knew the format I needed.So I tried a different idea: what if renaming the file actually converted it?Morpholder watches folders and performs the real conversion when the extension changes.For example:favicon.png → favicon.ico photo.heic → photo.jpg video.mov → video.gif video.mp4 → audio.mp3But it also unlocks some workflows beyond simple conversions:- Append _nobg to an image → background is removed automatically (uses Apple’s subject detection) - Rename an image to .txt → text is extracted from the image using Live Text - Append _min → compress image for the web while preserving quality - Rename an image to .icns → builds a macOS app icon package - Append _pages to a PDF → exports each page as high-resolution imagesThe app ru

Show HN: Liftstack – Snippet-level A/B testing for CRM marketershttps://www.liftstack.com/I've spent years in CRM and email marketing, and one thing has always driven me mad: the constant pressure from the business to "test everything" when you know damn well you'll never reach statistical significance.Most ESP's use frequentist models. You need a fixed sample size calculated upfront, you can't peek at results early without inflating your false positive rate, and if your list isn't massive, you're waiting weeks for a result that often comes back inconclusive anyway. So teams either ignore the statistics entirely and just pick whichever variant "looks better" after a day, or they stop testing altogether. Either way, you learn nothing.On top of that, the testing workflow itself is painful. You duplicate your entire template, change the one thing you want to test (a subject line, a hero image, a CTA), split your audience, send, and wait. Want to test two things at once? Now you need four template versions. Three things? Eight versions. It scales terribly, and most teams just d

Seedream 5.0 Lite API Pricing Breakdownhttps://news.ycombinator.com/item?id=47146196Seedream 5.0 Lite just dropped. Seedream 5.0 Lite just dropped. If you're curious about the most cost-effective way to run this in a production workflow, I put together a quick breakdown of the features and a price comparison across a few providers.1. Seedream 5.0 Lite Key Enhancements Here is what stands out in the 5.0 Lite update: - Stronger Feature Consistency: Noticeable jump in facial consistency and detail when using multi-image references. - Detail Preservation: It maintains natural skin tones and postures much better across batch outputs. - Precise Instruction Following: Handles complex camera angles and specific brush-style effects more reliably. - Multimodal Reasoning: You can feed it rough sketches or abstract logic, and it translates them into commercial-ready designs. - Visualizing Complex Data: Great for turning raw data or knowledge sets into clean visuals for presentations. - Broad Use Cases: Fast enough for marketing/E-commerce but high-quality enough for film/game pre

Show HN: PaperBanana – Paste methodology text, get publication-ready diagramshttps://news.ycombinator.com/item?id=47132143I got tired of spending hours in PowerPoint and TikZ drawing methodology diagrams for my papers. So I built PaperBanana — you paste your Method section text, and it generates a publication-ready figure in about 2-3 minutes.How it works under the hood:1. A Retriever agent searches a curated database of real academic diagrams to find structurally similar references 2. A Planner agent reads your text and generates a detailed visual description (layout, components, connections, groupings) 3. A Stylist agent polishes the visual aesthetics without changing content 4. Then it enters an iterative loop: a Visualizer generates the image, and a Critic evaluates it and suggests revisions — this repeats 1-5 times (you choose)The key insight is that academic diagrams follow conventions — Transformer architectures, GAN pipelines, RLHF frameworks all have recognizable visual patterns. By retrieving relevant references first, the output is much closer to what you'd actually put in a paper vs. generic A

Show HN: Irpapers – Visual embeddings vs. OCR trade-offs in scientific PDFshttps://github.com/weaviate/query-agent-benchmarkingHey HN, we are releasing IRPAPERS to answer a highly pragmatic question: when building a RAG pipeline over PDFs, should you OCR the text or just embed the raw page images?Processing PDFs in production usually involves stringing together brittle OCR heuristics. While recent multimodal embeddings (like ColModernVBERT or ColPali) allow you to skip OCR entirely and retrieve directly from visual layouts, we wanted to measure if the computational overhead is actually worth the utility.The short answer: Transformer-based image pipelines won't be perfect for every use-case, but they fix exactly what OCR breaks.Here is what we found benchmarking 3,230 pages of dense scientific literature:Complementary Bottlenecks: Text representations (BM25 + dense vectors) are highly efficient for exact lexical constraints (e.g., finding a specific acronym like "HyDE"). Conversely, image embeddings shine on spatial architecture diagrams and t-SNE plots where OCR serialization just turns into structural garbage

Instance segmentation model that extracts 3D geometry from 2D floor planshttps://news.ycombinator.com/item?id=47092547Hey HN,I am an ML Engineer and a full-stack software engineer. For the past few weekends, I have been working on a pipeline to solve a PropTech problem: turning messy, highly occluded 2D floor plans into clean, structured data for 3D extrusion. Originally demoed for a firm hiring for the role.The Problem: If you try to use standard object detection (bounding boxes) or basic OCR (tested Qwen, DeepSeek) on architectural plans, it fails instantly. Walls intersect, doors swings and dimension lines heavily occlude the actual structures.The Stack & Architecture: I built an instance segmentation pipeline that relies strictly on pixel-perfect masking to pull the geometry.The Backbone: Swin Transformer + Detectron2.Model trained on 1024X1024 images, with RTX 4090Inference: Inference on CPU

Show HN: Small "AI slop" classifier running in a browser extensionhttps://github.com/distil-labs/distil-ai-slop-detectorWe used our distillation platform & a Kaggle dataset to produce a tiny (270M Gemma base) model to classify text into "AI slop"/not classes.It's fun to play with and was fun to build, too.Annoyingly formal, human-written text (e.g. an ML paper I wrote back in 2015) tends to get misclassified (try "Manipulated images lose believability if the user's edits fail to account for shadows. We propose a method that makes removal and editing of soft shadows easy. Soft shadows are ubiquitous, but remain notoriously difficult to extract and manipulate. We posit that soft shadows can be segmented, and therefore edited, by learning a mapping function for image patches that generates shadow mattes. We validate this premise by removing soft shadows from photographs with only a small amount of user input").
