NASA Webb Explores Family Tree of Newly Discovered Distant Objectshttps://science.nasa.gov/missions/webb/nasa-webb-explores-family-tree-of-newly-discovered-distant-objects/Since their discovery by NASA’s James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has been a puzzling scientific endeavor. One popular theory is that little red dots are supermassive black holes known as active […]

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 t

Show HN: Experiments with Weather Datahttps://strataweather.com/mapI had been wanting to try experimenting with nowcasting since the death of Dark Sky and finally got around to it. This application essentially became a playground for me to experiment with various weather datasets and geospatial visualizations.Some interesting concepts that came from it:The nowcast is using pySTEPS optical flow under the hood: https://pysteps.readthedocs.io/en/latest/auto_examples/plot_.... This library is super cool. It bugged me that every radar visualization just gave you choppy snapshots in time, so I spent some time working on building a smooth interpolation. The backend passes keyframes along with motion data from the optical flow analysis and then has a custom WebGL shader to do the interpolation which lets you scrub the timeline and have a smooth interpolation.The other forecast tiles and the main weather page are using the average of many different weather models. You can see every model that factors in on the models page: https://strataweather.com/models. Thi

Show HN: Shoebox Plus Organizer – search, sort, and filter your Ancestry Shoeboxhttps://chromewebstore.google.com/detail/shoebox-plus-organizer/ncmfpkikgbnacbiipnbnfdohjpbgjjkhAs a genealogist for nearly two decades, including a stint as a Research Manager for Ancestry's research arm, AncestryProGenealogists, I have heard colleagues and clients alike complain about the "Shoebox," an Ancestry record bookmarking tool, lacking a mechanism to search, sort, and filter content. Once you've saved a few hundred documents, you must endure an endless paginated scroll, 25 records at a time.My solution: Shoebox Plus Organizer — a Manifest V3 Chrome extension that loads every page of your Shoebox in the background, then provides live full-text search, date sorting, and record-type filtering, all client-side over the DOM that's already rendered on the page.Everything runs on-device. No servers, no external API calls, no analytics. There's nowhere for the data to go. It doesn't scrape or automate faster than a human clicking through pages. Shoebox Plus Organizer reformats what's already loaded. Works across all 11 international Ancestry sites (.com, .co.uk, .ca, .com.au, .

Show HN: My First OSS as a Teenhttps://openotp.appHey! I'm Jenin, a 14 year old in Toronto, Canada! This is my first proper Open Source software I made, called OpenOTP! I have 6 emails :sob: and grabbing OTP's from them can be hard, even with a good email client. So I built this tool to make it easier for me! I made it in native Swift :)I did this for Hack Club Horizons, which is an event where they're flying teens to 7 countries around the world for hackathons! You can find out more about Hack Club at https://hackclub.com and horizons at https://horizons.hackclub.com.I'd love if you guys could check out my software and let me know what you think :)

We help companies build custom models from their data.Today, we’re releasing FeyNoBg, an automatic background removal model. Alongside it, we're open-sourcing NoBg, the Python library we built to train and run it.Try the model here: https://huggingface.co/spaces/feyninc/feynobg.

Ask HN: 1950's Chip industry undermined unions how is AI not doing the same?https://news.ycombinator.com/item?id=49064165In the 1950s the Chip industry undermined minorities, immigrants, women and killed unions.In the 1960-70s it targeted black civil rights groups.Along the way, white men were pushed into management, while anything outside of business was split into smaller tasked jobs. This in return gave companies leverage to cut salaries.I don't care what altman says chatgpt did in a blackbox. I judge the world by what I see. Reality is, chat, claude, etc etc are about as useful as smart as the stupidest, slowest engineer on the team.On the other hand, introducing them has made the job appear more "streamline" more production line like. Work increased, and salaries flattened.Now that companies are not getting returns off of AI, they are cutting AI spending, but make no mistake. Salaries will not recover.What am I missing? How am I wrong?Would love opinions on this

We need to rethink tech stackhttps://news.ycombinator.com/item?id=49061251Let me start this with something we already know, AI is here, it may be controversial how it will operate open or closed but its not going anywhere.If you look at the current tech space, AI integrations and use and some very useful but some unnecessary AI implementations, you will realise that there are either many gaps in current understanding.Lets start on what i wanted to talk, first lets talk about AI, what is AI, not the defination, but actually is AI, it may not be the ultimate intelligence but have some intelligence or atleast we can say, it know certain well known patterns, its ability comes in various sizes, but essentially now we a black box with some knobs, which be a better solution than hard coded flows, logics and if its imagined well, it can be really really useful but there is a flaw.We being extremists, we either think of its going to taking all the jobs or its just useless, there is another way to approach it.Think of it as intelligence layer available to you, but cur

Show HN: Scanner for cellular automata rule spacehttps://kypaku.github.io/pages/ca2026/Many years ago I was interested in cellular automata, inspired by Stephen Wolfram's work. I dug into elementary CA and totalistic 3-state rules. But when I went to more states it was getting boring. Almost all of them are dead or chaotic or something that everybody has already seen. But somewhere inside there could be another 110, and nobody looked.Now that we have AI coding, I decided I can build something in that area, and an app for scanning rules was the obvious thing. I implemented an explorer with a bunch of filters: gliders, chaos, large structures, and custom search. The last one works backwards — you draw a pattern and a rule passes only if this pattern never occurs. I could not define "interesting", but it was easy to say what disqualifies a rule. It also renders diagrams as big PNG.Demo: https://kypaku.github.io/pages/ca2026/ Source: https://github.com/Kypaku/ca2026

ASK HN: Why has technology become so unreliable?https://news.ycombinator.com/item?id=49056900Even though I'm a software engineer with long experience with serious projects, I'm become so disillusioned with the whole thing nowadays.Forget the ridiculous AI hype, forget about the lack of ethics and a moral compass; What's getting to me right now is the unreliability of it all. It seems like everything is held together with duct tape, and the tape is falling off.Just in the last few months, all these have happened:- My Macbook Air M1 has been acting up, refusing to charge in a stable manner. The audio jack is dead because apparently it is linked to the charging circuit. The screen sometimes shows a tint on a whim. Now it is dead and not charging at all. Granted, it has otherwise been a fine machine so far, and I've knocked it over a few times, but still. Even my old trusty 2014 Macbook Pro is still going strong, and I've abused that one much more.- I also can't use my old Macbook Pro well, because the replacement Transcend 256GB SSD I put in it around 2020 is now failing, causing
