Spin audit of SQD/QSCI quantum-chemistry benchmarks on iron–sulfur clustershttps://zenodo.org/records/21359923Author here.Background, for anyone who hasn't followed this fight: IBM's iron–sulfur SQD results (Sci. Adv. 2025) are one of the flagship "quantum computers are useful for chemistry now" claims, and a published critique (arXiv:2501.07231) argues the quantum samples never beat classical selected-CI at matched cost. That argument is still live.Both sides have been arguing about energies. Neither measured which electronic state these calculations actually converge to.So I measured it. ⟨S²⟩ comes out between 4.7 and 7.0 depending on the system and the subspace size, where the target these papers name is a singlet at ⟨S²⟩ = 0. Every starting guess I tried lands in the same place, and the error at convergence is about the size of the spin-state ladder itself, which is the physics under dispute.IBM ships a mitigation for this. Run exactly as shipped, using their driver, their recovery loop and their own spin_square() diagnostic, it moves the ground energy by under a nanohartree while making tJul 29, 2026 1:13 PM

Show HN: Skim – a minimalist open-source email client for Windows (MIT)https://skim-tech.com/I built Skim because I was super dissatisfied with all existing Windows clients.I mean, it's not a rocket science, there should be some lightweight modern solution, isn't it? So I decided to create a client that just, you know, MAKES SENSE and has design younger than dinosaurs.Key points:* Obsessed with installer size: it should be under 5Mb.* BYOK AI. Cowriter, agentic search, summarization and other AI stuff is powered by your own key for Anthropic/Openrouter, or you can connect your own OpenAI-compatible server (including local)* No bloat. It should be as contextual as possible: gives you right button when you need it. No menu at all. No integrations. Just email.* Instant startup, super modest on resources* Cool warm zine design with paper colors and really calming vibesIt's MIT - contribution and stars are welcome!Jul 23, 2026 9:12 PM

Show HN: Velprium - Time Workspacehttps://www.velprium.com/Hi HN, I'm Minjae, a solo developer.- About two years ago, I came up with an idea and worked on it as a side project for about three months, but I had to quit because I was overwhelmed by my main job.However, when I recently used a coding agent to configure the specifications and have the development done, the implementation speed was incredibly faster than it was two years ago. So, I focused on refining the specifications and rode that momentum to launch the service in just two weeks.- The reason I developed Velprium was the problem of my data being scattered across multiple places when recording my day. Calendar, Notion, Obsidian, and various other collaboration tools...I even tried a paper bullet journal, but I failed every time I had to transfer notes between digital and analog formats.That led me to think, "What if I added Notion's properties to calendar events?" Traditional calendars consist of an x-axis representing time and a y-axis limited to just title and description. So I aJul 20, 2026 9:30 PM

Show HN: Jacobi–IDE for Abaqus subroutine with analytical tests and AI diagnosishttps://jacobee.netlify.app/I write Abaqus UMAT subroutines as a graduate student in computational mechanics. These are complex multi-physics simulation models using Abaqus Fortran subroutines (UMAT ~ mechanical behavior, UMATHT ~ heat/diffusion and a lot more) that simulate how different material systems fail under high temperature or manufacturing processes.However, the entire process has been quite challenging, 80-90% of time is actually spent on how make Abaqus CAE simulate a physics you already know on paper or what are the correct subroutines and variables you should use. Huge time is also spent on diving deep into the .sta .msg files to figure out and debug why a simulation failed. The software or current tooling (IDE ~ which is VS Code etc built for software engineering, not computational physics or mechanics) doesn't tell you why the simulation run into a segmentation error, or warn you when your damage variable being 1 (fully damaged) will lead to a zero division error.

Show HN: Scan2Sheet – Receipt Scanner to Google Sheets for easy expense trackinghttps://www.scan2sheet.comAfter several months of development and refinement, my mobile app, Scan2Sheet, is finally published and live on Apple Store and Play Store.The idea for Scan2Sheet came from a problem I had myself: managing piles of paper receipts for tax deductions and expense tracking. Manually entering receipt data into spreadsheets is time-consuming, tedious, and prone to errors. On top of that, paper receipts can easily be lost, damaged, or overlooked.With Scan2Sheet, simply take a photo of the receipt whenever making your purchases. In just a few clicks, the extracted expense data and a copy of the receipt image are automatically saved to your own Google Sheets document. There's minimal manual data entry, and no need to learn or manage another dashboard, database, or accounting system.Here are the links to download:- For IOS: https://apps.apple.com/us/app/scan2sheets/id6760991697- For Android: https://play.google.com/store/apps/details?id=com.app.scan2s...The product's landing page: https://www.scJun 2, 2026 12:38 PM

Show HN: Hackobar – One feed for AI newshttps://hackobar.com/Hey HN,Out of frustration of keeping up with AI news, I built hackobar. It fetches the AI related news from multiple sources such as HN, arxiv, github trending repos, huggingface, many ai subreddits, twitter handles that cover AI, Tech news outlets, major ai lab blogs and of course the numerous AI news letters that are growing by day.GitHub trending repos isn't "news" but as an engineer it matters. you can't read every arXiv paper or every HuggingFace drop. HN has the best discussions, Twitter has some, newsletters have some. I used to check 5 places and still felt behind.Building this was fun. I had to face many technical challenges, even though I have used Claude Code to help build I think the decisions I took to mitigate those challenges are interesting and wanted to share with this crowd.1 Fetching: I had to fetch different sources at different rate because fetching some on regular bases didn't make sense. for example, fetching AI labs blogs every few hours does not make sense but May 25, 2026 4:02 PM
