Nighttime Imaging Grows Landsat’s Science Valuehttps://science.nasa.gov/missions/landsat/nighttime-imaging-grows-landsats-science-value/By Earth Resources Observation and Science (EROS) Center For more than 50 years, Landsat has imaged Earth’s land and near-shore surfaces as the satellites descend in midmorning orbit, when daily sunlight is optimal. That’s just what they’ve always done. Currently, Landsat 8 and Landsat 9 circle the globe while also making better use of their ascending paths, […]

Show HN: I built a toy that plays grandma's stories when my daughter hugs ithttps://www.storyfriend.co.uk/This was a project I built for my daughter's first birthday present.For context, I'm a surgical resident in the UK by background and am currently taking a year out of training to study a masters in computer science. My daughter just turned one. There are two things she really loves: the first is particular soft toy that she just can't live without, and the other is a good story book.Her grandparents live hours away and I didn't want her to forget what they sound like between visits. I wanted her to hear them whenever she missed them.My parents brought my brother and I up with incredible stories and books from all sorts of cultures, many of the stories being passed down from their parents before them. I didn't want my daughter to miss out on that.Finally, I was sick of missing storytime with her when I had to leave for night shifts. I wanted her to hear my voice before she slept every night.For all these reasons, I decided to build Storyfriend. It's her favourite soft toy with a custom

Show HN: Core – open-source AI butler that clears your backlog without youhttps://www.getcore.me/Hi HN, we're Manik, Manoj and Harshith, and we're building CORE (https://github.com/RedPlanetHQ/core), an open source AI butler that acts and clears out your backlog.Write `[ ] Fix the search auth bug` in a scratchpad. Three minutes later, without you at the keyboard, CORE picks it up, pulls the relevant context from your codebase, drafts a plan in the task description, and spins up a Claude Code session in the background to do the work. You review the output in the task chat and unblock it when it gets stuck.Every AI tool today is reactive. You open a chat, brief the agent, it responds. Before anything moves, you've already done the real work: opened the Sentry error, found the commit, read the Slack thread, grabbed the Linear ticket, and stitched it all together into a prompt. The model isn't the bottleneck. You are.Demo Video: https://www.youtube.com/watch?v=PFk4RJvQg1YCORE removes you from that loop. The interface is a shared scratchpad, think a page you and a colleague both have o

Show HN: Notation – an iOS chess coach (Stockfish on device and optional BYOK)https://notationchesscoach.appHi HN. Solo iOS middle aged, slightly burnt out dad from the UK here, wondering if anyone is interested in what I've been building. Lifelong chess fan, not very good but always trying to improve and I started to build Notation: Chess coach a while back. It's been live a month now on the App Store, doing modest numbers, and I've been learning a lot... mainly make my add brain slow down, stop, test everything twice and never when tired. Submissions will always wait another day!Many people play on chess com, or lichess, just as many in apps and OTB. What my app does (differently I hope) is bring that data together.You can import PGNs of your games, connect to chess com and lichess and sync your games over or play in the app. If you have a Chessnut electronic board, you can play IRL on that as well.Every game, every move is then analysed by a series of on device detectors, and classifiers. And I'm not talking about"I run Stockfish 18 and get your move evals" like most tools do.... Theres a

Instead of writing my manuscript, I built a toolhttps://news.ycombinator.com/item?id=47849297Hi my name is Jeff, and I am a chronic procrastinator when it comes to my writing…Tell me that doesn’t sound familiar, I’ve literally written two blogs about this instead of actually writing my manuscript, cause literally anything (even scrubbing the toilet) is more compelling than the grind of getting through chapter 6.I actually started writing a tool in early January 2025. At the time, I was trying to find a way to gamify my writing. I wasn’t really looking to launch a serious writing tool at the time, just find a way to hack my brain into doing the work (and find another excuse to not write).The result of that was a simple text box with a word counter (0/500 words) that used a little bit of JavaScript to count the words you dumped in the box, deduct any shorter than 3 letters and then let you know if you hit your writing goal for the day (and you even got some fireworks!)The tool worked, I found myself anticipating pasting my daily writing progress into the box for that dopamine re

Ask HN: Would you use revocable digital signatures to verify AI/Other content?https://news.ycombinator.com/item?id=47848539I’ve been exploring a potential product direction and wanted to sanity check it with people who actually build and ship things.Background: I’ve been working on a system using our core tech that can generate and verify digital signatures, but with a slightly different property than traditional approaches. The signatures are natively revocable. If the underlying model/system shouldn’t be trusted anymore, the signatures can be revoked either through a hard (delete the signing model) or soft (revoke the lease for the signing model) mechanism. I believe this feature is very beneficial on its own, but there are several other interesting properties (no key management, distributed verification, embedded metadata, etc.)Originally this came out of some deeper R&D work we’re doing, but I’ve been thinking this might actually be the most practical “wedge” into the market while we continue that research (and fund the research).One area that’s been interesting is applying this to AI systems.

Show HN: Weekly Log, Old-school journaling social mediahttps://news.ycombinator.com/item?id=47843663Weekly Log is a minimalistic social media website designed for you to do journaling and creative writing.A lot of modern social media apps are set up in a way that addicts and detriments the users, meanwhile profiting off of their data. I really wanted to make a site that doesn't operate in that way.Some of its distinctions: - You can create one post per week. This encourages care and consideration. - Nobody knows who you follow or what posts you react to, besides you and the other user. These stats are personal, so people view your logs free of outside influence. - Posts are rich text-only, no images or videos, in an effort to reduce mental clutter. - Your feed only features users you follow, to give you increased control of what you see, unless you click the "global" checkbox to see all posts.quick demo: https://www.youtube.com/watch?v=7CTnORsGnL8 overview page: https://www.weekly-log.com/about/overview---I have soft-launched this website, and a handful of my friends have signed up a

Observability Stack – AI First?https://news.ycombinator.com/item?id=47819461So... I'm way behind. Just got into Claude this week... it's already doing most of my coding and bug fixes. Crazy stuff.Some background on my company: Mature (14 yrs) Ruby on Rails app, Sidekiq, Redis, PG, AWS lambda/eventbridge, react/preact, swift, and others. Hosted on Heroku. Very database heavy. Solo guy, owner/operator.Current stack:Datadog logging (dabbled in APM, metrics, and others, but the build pack for Heroku is so bloated I had to remove it), so now it's a simple Heroku log drain to datadog. I really miss the statsd host and APM stuff... but it took my slug size from ~250mb to over 350 and made booting and deploys much slower. I'd also like to get off Heroku.... some day... but I can't event fathom it.Bugsnag for errors. Already moved this to Sentry to try out the AI stuff.A little fed up with Datadog and receiving $600 monthly bills on top of my enterprise commitment. biggest pain points: indexing is priced per line, not by gb (discourages me from simple logging, so I res

Show HN: Co-op: Your 24/7 Digital Internhttps://app.subconscious.dev/AI is in a weird place right now. Technical people marvel over it while non-technical people don't really care.So we built Co-Op, an app specifically designed for non-technical people to run AI agents without needing a Mac Mini or laptop running 24/7. Your agents run throughout the day and complete real work across your most important apps, no code required.For me, this looks like a daily notification with my unread emails across Outlook, Gmail, and any other inbox, the weather, commute time, flight prices I'm monitoring, and the news. But it goes way beyond that. Our agents can build slideshows on Google Slides, track your finances, follow sports scores, summarize and write documents, manage your calendar, and a lot more. All running in the background without you having to constantly prompt.

Why Vibe Coding Failshttps://news.ycombinator.com/item?id=47778946i am using claude to maintain an agent loop, which will pause to ask for users' approval before important tool call. while doing some bug fixes，i have identified some clear patterns and reasons why vibe coding can fail for people who dont have technical knowledge and architecture expertise.let me describe my workflow first - this has been my workflow across hundreds of successful sessions: 1. identify bugs through dogfooding 2. ask claude code to investigate the codebase for three potential root causes. 3. paste the root causes and proposed fixes to claude project where i store all architecture doc and design decision for it to evaluate 4. discuss with claude in project to write detailed task spec - the task spec will have a specified format with all sorts of test 5. give it back to claude code to implement the fixin today's session, the root cause analysis was still great, but the proposed fixes are so bad that i really think that's how most of vibe coded project lost maintainability

Show HN: HWT (Hash Web Tokens) – minimalist protocol for auth statehttps://www.jimmont.com/hwt/My frustration solving auth with JWTs led to reinventing the wheel for more predictable token integrity and transparency, while improving flexibility. The mix of features separates concerns more cleanly than what's been available, allowing higher throughput, custom codecs, delegation to both services and domains while easing key rotation and other practicalities.The design is focused on the token as state guarantee, not creation, revocation and the range of other separate concerns and application responsibilities. The spec conventions attempts to ease development with jurisdiction/data sovereignty and authorization in the authz field. It also enables and eases delegation between services and domains without centralized service exposure. The implementation is standalone and has demos for Deno, Cloudflare, etc in https://github.com/hwt-protocolFeedback and critique of the security logic and approach appreciated.
