NASA Finds Young Stars Dim in X-rays Surprisingly Quicklyhttps://science.nasa.gov/missions/chandra/nasa-finds-young-stars-dim-in-x-rays-surprisingly-quickly/Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal. Unlike in the new movie “Project Hail Mary,” this quieting […]

Nutrition Research Arrives Aboard Space Stationhttps://www.nasa.gov/missions/station/iss-research/nutrition-research-arrives-aboard-space-station/No matter how far humanity aims to travel or how ambitious the mission, nutrition will play a key role for the crew members on distant worlds. Before planning long-term stays on the Moon, Mars, and beyond, humans must learn to grow and care for plants and other sources of nutrition like algae to keep the […]

Show HN: iOS app that continuously turns contact dates into calendar eventshttps://keepdates.appI built KeepDates after realizing I kept missing important dates that were already saved in my contacts.Birthdays are automatically handle by iOS, but everything else was just ignored. I always dutifully curated my contacts, adding different dates to each (friends' kids' birthdays, anniversaries, significant events), but always seemed to forget about them as the day approached. I tried manually adding them to my calendar, but it quickly became annoying to maintain.So, this app is just there to handle it - it runs in the background (as much as that's possible on iOS) and periodically checks for changes to the contacts, and updates a separately maintained calendar with new dates/events (or removing ones that disappeared). That way, I can be sure that when I update a contact with new date information, it will be reflected in my calendar, and I'll get alerted on time.That's it... that's the app.It also has a bunch of different toggles, customizations, notifications and widgets, if handling

Show HN: Specsight – Living product specs generated from your codebasehttps://specsight.appHeyy HN, I'm OlaI'm an engineer myself, and everywhere I've worked there was a similar dynamic: someone from the non-technical side of the team (PM, CS, stakeholders) needs to understand what changed recently or how something works today. They rely on stale Confluence pages or ping engineers in Slack and wait. engineers get interrupted daily answering "how does this actually work". it's a mess that gets worse as the team growsor when you join a new company and try to get a sense of the product. turns out the documentation doesn't exist or is months old. you ask 5 people and get 5 different answers. I've seen it and experienced it sooo many timesI decided to start exploring this space and built Specsight for those non-technical teams. it connects to your GitHub repos, analyses the codebase with Claude (Agent SDK), extracts business-level features of the product, and generates plain-language specifications in Context/Action/Outcome format for every feature. it also builds a visual graph

Ask HN: Would you take your engineering team to Buenos Aires for an offsite?https://news.ycombinator.com/item?id=47726018Hey HN,I’m doing some market research on the logistics and viability of hosting corporate tech offsites in Buenos Aires, Argentina.With the shift to remote/distributed work, annual or bi-annual company retreats have become the main way teams build rapport. We see a lot of teams going to Mexico City, Lisbon, or Costa Rica, but I'm looking closely at Buenos Aires (as I live there).Timezone: Favorable for the US (EST +1 or +2) and easier for EU overlap.Cost: Highly favorable exchange rate makes luxury/premium experiences much more affordable.Culture: World-class food, infrastructure, and a strong local tech ecosystem.However, the flight time from the US West Coast or parts of Europe is significantly longer than going to Mexico or Portugal.I’d love to hear from founders, CTOs, and engineering managers who have planned or attended company retreats:1. Has your team done an offsite in LATAM? If so, where, and how did you choose the location?2. Is flight duration the ultimate dealbreaker? Woul

Show HN: BNNR – a closed-loop pipeline for improving vision modelshttps://news.ycombinator.com/item?id=47719542Hi HN,we’ve been working on computer vision models for a while, and one thing kept coming up: improving them is surprisingly unstructured.You train a model, try a few augmentations, tweak some hyperparameters, run it again - and if the metric goes up, you keep it. But it’s often unclear why it improved, or whether the model is actually learning something better.We kept running into questions like:- Did this change actually help, or is it just noise?- Is the model focusing on the right features?- Are we improving generalization, or just overfitting differently?So we built BNNR (Bulletproof Neural Network Recipe) - an open-source PyTorch toolkit that turns model improvement into a closed loop:- Train a controlled baseline- Explain what the model actually learned (via XAI methods like OptiCAM / GradCAM)- Improve by testing candidate strategies in parallel- Prove the result with structured comparisonsOne thing we focused on is avoiding “blind” changes. Instead of committing to a single ide

Show HN: Lingle – Voice agent to simulate zoom-based personal language lessonshttps://lingle.ai/In my opinion the best way to learn a language (outside of moving to a different country) is to get a personal tutor and have consistent 1 on 1 lessons. I used Preply or iTalki for this back in the day but had issues with flexibility and pricing.I've been trying to simulate the experiences that I had on those platforms with a voice agent.You can try a demo for free here (or watch a video of me using it on the landing page):https://lingle.ai/tryout/lingle-showcaseRight now the agent can plan a lesson with visuals and a conversation focus, guides the user through the lesson - correcting and explaining things on a whiteboard if necessary, and asks relatively engaging questions. There is also a long term user model that builds over time, that maintains memory of the user's produced vocabulary, grammar, and skills, meant to make each lesson informed by the past and build on the user's knowledge (obviously this is still relatively fragile in practice).The voice agent itself has actually dece

Show HN: Helm Terminal – Free portfolio intelligence that tells you what to dohttps://helmterminal.devHi HN,I'm the solo founder of Helm Terminal (helmterminal.dev). It's a free portfolio analytics tool that connects to your accounts via Plaid and surfaces actionable insights and intelligence. Concentration risk, tax-loss harvesting, earnings exposure, idle cash, sector drift, etc. Automatically, every day.Every other portfolio tracker/brokerage I've tried showed me balances and pie charts but never informed me what to do or what was going on. I'd check my accounts, see things were generally "fine", and move on. Then I realized I'd been sitting on thousands of dollars in unharvested tax losses, 60%+ of my portfolio was exposed to tech, and I didn't know half of my positions were reporting earnings soon.Helm is the tool I built to fix all of these issues, and a tool I wish existed. It runs on a set of intelligence engines on top of your connected accounts and gives you a prioritized inbox of things worth doing, as well as news tailored to your holdings worth looking at.
