Ask HN: Add flag for AI-generated articlesShould HN add the ability to flag articles as AI-generated? This doesn't have to act as a regular flag, i.e., it won't de-rank the article; it could just show up as an indicator, allowing others (like myself) who don't like reading AI-generated text, to skip it.Open questions:1. Why is the regular voting system not enough?2. Should HN change in response to the gen AI era? It has been successful not changing fundamentals.

Show HN: Clark – AI assistant with own computerHey folks, I've been building Clark solo, with the aim to match Manus agent (I really like it!) in features and capabilities, but also in its relentless ability to just complete tasks while using browser, computer etc. So far I think I've achieved 1:1 core feature parity: 1) computer use agent 2) browser use in same thread 3) wide and deep research - clark calls clark 4) integration with google toolsWould love to have community feedback and for you to try it out, a couple thousand people already using it daily for very broad use cases.You can use this referral link, that hopefully works and grants credits :-)https://www.clarkchat.com/login?ref=CLARK-A10K9Z3Q

Show HN: Hologram, photo management and culling built with TauriHello Hacker News photographers! Yes, this is essentially my take on photo colling and management, similar to the features that Lightroom and Darktable already have.Because I shoot in JPEG+RAW, my workflow looks like me going through my JPEG images and then eliminating the JPEGs I don't like afterwards in addition to their corresponding RAWs. At least on my old MacBook, the JPEGs were faster to load than the RAW photos (probably a combination of CR2, the file my EOS 40D, not having embedded JPEG previews and my buggy macOS version). Hologram would be my way of making this workflow easier to do, especially with keyboard shortcuts.I also never liked the star-based system on Lightroom or Darktable, so I implemented Pick and Reject instead (which matches what I would otherwise do with deleting photos to my system trash when I cull in the Finder app)Anyways, with my new R7 I found that bursts got more annoying to cull so I decided to create autocull on Hologram as well. This would analyze y

Ask HN: Would filesystem bookmarks be useful in your shell workflow?I’m experimenting with a small shell utility for filesystem bookmarks, and I’d like to understand whether this is a problem other people have.The idea is to define persistent or temporary bookmarks for directories:``` bm add work ~/Work bm temp build /tmp/build ```and then use them directly in paths:``` cd @work ls @work/project ```The utility would also support renaming bookmarks, promoting temporary bookmarks to persistent ones, demoting them, and clearing temporary bookmarks.I’m not sharing the implementation yet. At this stage, I’m mainly interested in how other people handle this today:* Do you use aliases, environment variables, shell functions, z, autojump, or something else? * Would explicit names such as @work be useful, or would they feel redundant? * Would temporary bookmarks be useful in real workflows? * What would this need to offer to be worth using instead of existing directory-jumping tools?

Show HN: Mosey Parker – find a ride in bikeshare systems worldwide (iOS)Mosey Parker began as a personal project. I use Citi Bike regularly in New York City, but I don't love their app for finding available bikes and docks. (And the less time I spend in Manhattan traffic squinting at a screen, the better.) I decided to build something I found easier to read and more efficient to use.I was pleasantly surprised to learn that Citi Bike is only one of many operators that publish real-time data using an open standard, the General Bikeshare Feed Specification (https://gbfs.org/). Mosey Parker currently supports over 1,000 systems worldwide, including major operators such as Bird and Lime, using a single consistent interface.Since most systems let people rent a bike/scooter with a credit card, it can be especially convenient for tourists: one app to find a bike and eventually dock it, without needing to install the local system app and create an account. I've used it in Montreal and Copenhagen, relying on a familiar map in unfamiliar places.

Show HN: Juggler – an open-source GUI coding agent, by the creator of JUCEHello HN, I don't post on here much, but wanted to get some eyes on a new project I'm just launching. I think we definitely need one more AI code agent..I'm a long-term C++ dev, and over 30+ years I've created some successful audio dev tools (JUCE, the Tracktion DAW, the Cmajor DSP language). All of these came from me getting annoyed with something I had to use, and deciding to have a go at my own take on whatever it was.So Juggler is my attempt at an AI code agent, after spending too many hours loving what the models could do, but hating the CLI experience, and having some opinions of what a better UX might be for this stuff.Lots more blurb on the website and github, but a quick tech dump which might grab your attention if you're into these things:A session is a document, not a log file. Each conversation is a Yjs CRDT tree. It can branch into sub-threads (recursively), and you can drill down, backtrack, edit, undo/redo, and inspect everything: tool calls, approvals, and the raw conte

Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7kThis started based off of a hunch. We usually use OpenCode, but were 'forced' to use Claude Code for a while due to issues with Meridian. In that time, we saw the usage meter rise much, much more quickly than when using OpenCode.This was the initial anecdotal evidence, but we undertook this small study to collect empirical data:We added logging between the agentic coding tool (Claude Code and OpenCode) and Anthropic's endpoint, and captured all requests (and the returned usage blocks).With one caveat (toward the end of the post) we found unambiguously that Claude Code was far more inefficient in terms of its cache strategy and its harness token usage than OpenCode.

Show HN: Pgnudge - tell your app which Postgres tables just changedGenuinely unsure if this is crazy or cool: looking for feedback.pgnudge is a small async Python library that tells you which tables just changed in Postgres, so a cache or read model can refetch the moment the data moves. No row data - it tells you when and what to reload, you already know how to load it.It leaves nothing persistent on the server (temp replication slot, dropped when the session ends) and needs no database driver — it speaks the walsender protocol itself. One dependency.Not CDC (no before/after rows), not a queue (no durability). It moves wakefulness, not rows or work.Repo: https://github.com/janbjorge/pgnudge

Show HN: The Line of Hope – how current teams compare to past championsI built this project, which I call "The Line of Hope". It is a concept that is meant to work for any major sports league. Currently, I have it available for the NFL and MLB, and it's most fun to follow for a league currently mid-season. The idea is to show every team's record in relation to the worst ever past champion through the same number of games in the season. For example, of all past World Series champions, through 40 games, the team with the worst ever record was the 1914 Boston Braves (12-28). If a team had a record of 10-30 through 40 games, they would be considered hopeless, with a Line of Hope Index of -2. You can use this site to see where current teams stand relative to the Line of Hope and how today's games affect current teams Line of Hope index (e.g. did teams lose hope, restore hope, etc.). You can also browse a grid of data to visualize the Line of Hope. Hope you all enjoy!

Ask HN: Bypass smartphone call apps? Silent VoLTE via RTP extensionhttps://github.com/sigureitimonnji/nvap-protocol [EN] I designed a protocol called NVAP to eliminate the need for vocalizing personal information during call center verification. Check docs/sequence.md in the repo for the core timeline logic.To bypass the strict API/kernel-level RTP restrictions of iOS/Android, I'm thinking of completely bypassing the native call app and handling it via the earphone layer (utilizing RFC 8285 / 9335 Cryptex).However, I am facing two practical challenges regarding the timeline and biometrics:1. The Inbound/Outbound Timeline Mismatch: If the other party answers instantly on an outbound call, or if the user presses the answer button before putting the phone to their ear on an inbound call, the VoLTE connection starts BEFORE the earphone is actually in contact with the ear, ruining the acoustic scanning timeline.2. Biometric Ownership: If the master biometric data is inside the smartphone's Secure Enclave, transferring data back and forth over Bluetooth int

Show HN: Itara – Distributed system topology as an explicit, executable layerHi HN, I'm Gábor, a software engineer from Budapest.I spent almost a decade designing, building and maintaining distributed systems, and I came to truly understand why a lot of people define software architecture as "the stuff that's hard to change later". Changing service boundaries, communication protocol or serializers is time consuming and risky. The past few months, I've been building Itara, my attempt to ease that pain.Itara takes the software topology that's currently spread across the codebase and configuration and infrastructure, and concentrates it into a dedicated, executable layer. This dedicated layer describes the topology as a directed graph, where the nodes are the components of the system, and the edges are the connections between them. The edges have all the properties of the connection, like the transport to use, the serializer to use, the failure handling strategy and so on. Colocated components, components running in the same process, are modelled with direct conne

Latest Debian 12 update opens MariaDB server to the internetI have a couple servers with Debian 12, running MariaDB. The servers were configured with bind-address 127.0.0.1:3306 so that any database connections are local.I upgraded to Debian 12.15 today, rebooted and checked open ports just to see if all services are running.To my surprise, MariaDB is no longer listening on 127.0.0.1:3306, but we have "init" listening on :::3306.It looks like default config has changed to use Systemd sockets. Which I guess is fine, but silently making your database server accessible to the whole Internet doesn't sound like a good idea.So, just PSA, if you rely on bind-address only, make sure you reconfigure the mariadb.socket settings.

Show HN: Kurvengefahr – browser CAD/CAM for pen plottersA few years ago I made a pen plotter attachment for Prusa MK4 (https://www.printables.com/model/827264-pen-plotter-attachme...) and at the time I didn't have a good way to turn artwork into G-code for it, and I put the project on ice for a while.I recently wanted to dabble in line art again and made a small browser app to make it easier. As agentic AI tools of 2026 are quite addictive, it rather quickly grew into something quite a bit more - an integrated browser CAD/CAM for pen plotters that covers everything from importing existing artwork, creating artwork from scratch, preparing for plotting and hardware integration. It includes some off-beat features like a Logo interpreter for turtle art and Graves RNN for handwriting synthesis and in addition to 3D printer pretending to be pen plotters it now also supports actual pen plotters based on EBB (AxiDraw) and GRBL firmwares through Web Serial.If you own an AxiDraw or a GRBL plotter, I'd very much appreciate it you gave it a try and giv
