Show HN: A browser extension to control Google's Random Number Generator https://ift.tt/H8LicdW

Show HN: A browser extension to control Google's Random Number Generator TLDR: Built a simple extension to see how easily client-side logic can be manipulated. It lets you pre-select the winner of a basic online raffle as a sort of "magic trick." First time posting a project on HN. First public github repo also. Keen on feedback. I was exploring how browser extensions can interact with and modify a page's state in real-time, specifically what kind of access was needed to intercept a process without breaking the UI. The test tool was a bit of fun on its own, so I polished it up and decided to post it here. https://ift.tt/foTZ8vn July 3, 2025 at 11:20PM

Show HN: I made a Chrome extension to export web element to code https://ift.tt/dnKp9Rf

Show HN: I made a Chrome extension to export web element to code Recently I'm working on CopyUI which is an extension to copy UI element from websites and export html(or jsx) and css(or tailwind). I'm building this tool in order to create better landing pages because I'm really not good at layout and colors. So I hope to learn from others' design and innovate later, not to simply replicate. https://copyui.online July 3, 2025 at 07:32AM

Show HN: I created a privacy respecting ad blocker for apps https://ift.tt/SHd3LC0

Show HN: I created a privacy respecting ad blocker for apps Hey HN, I’ve been working on developing my ad blocker for the last number of years and am proud to share that I have now released a new feature that blocks ads directly in apps — not just in a web browser. What makes this app ad blocker feature special? - All ad blocking is done directly on device, - Using a fast, efficient Swift-based architecture (based upon Swift-NIO) - Follows a strict ZERO data collection and logging policy - Blocks ads in all apps on iPhones, iPads and Macs It works as a local VPN proxy, so it filters all of your traffic locally without going through any third-party servers. The app ad blocker works across News apps, Social media, Games and even browsers like Chrome and Firefox. After using ad blocking in Safari for a long time, it is eye-opening how many ads and trackers are also embedded in apps themselves. The app is available via the App Store, with a 30 day free trial, before an annual subscription is required. I know there are many other ad blockers available, but I hope the combination of performance, efficiency and respect for privacy will mean that this particular feature is a valuable option. It also took a LOT of work to get this working seamlessly within the App Store and iOS / macOS limitations, so am glad the app has been able to finally be released into the world. Full details on the feature are in the release post: https://ift.tt/WkLJSYQ https://ift.tt/WkLJSYQ July 3, 2025 at 06:34AM

Show HN: Issue Duration Labeler – a GitHub Action that labels issue by age https://ift.tt/gWT3o9N

Show HN: Issue Duration Labeler – a GitHub Action that labels issue by age I’ve built *Issue Duration Labeler*, a GitHub Action that automatically adds *color-coded duration labels* to every issue in a repo: Default label thresholds: Green – ≤ 7 days (configurable) Orange – ≤ 30 days Red – > 30 days For open issues we compute “age” (creation → now). You can adjust the day thresholds and label colors in the workflow file, and choose whether labels update daily or only when they cross the next threshold. *Why?* I often lost track of how long tickets had been lingering, especially in older projects. A quick glance at the issue list or github project now tells us what’s fresh, what’s getting stale, and what’s officially ancient. It’s also handy for post-mortems: sort by red labels to see which bugs took the longest to close. *Link* https://ift.tt/pWz520B... https://ift.tt/RrZx8z7 July 3, 2025 at 03:15AM

Taken with Transportation Podcast: Tip of the Cap (and Gown) to Our Dads and Grads
By Melissa Culross

Parking Control Officers Lloyd Glover, Willie Moore and Harold Laughlin are among the dads we profile in our new podcast episode. A lot of things happen as spring ends and summer begins. The days get longer. The weather warms up, in most places, anyway. As we know, San Francisco has its own definition of “summer weather.” And we celebrate dads and grads. In honor of Father’s Day and graduation season, we are profiling some of our own dads and grads in a special episode of our Taken with Transportation podcast. “Tip of the Cap (and Gown) to Our Dads and Grads” features eight members of our...

Show HN: Core – open source memory graph for LLMs – shareable, user owned https://ift.tt/2eL9jK6

Show HN: Core – open source memory graph for LLMs – shareable, user owned I keep running in the same problem of each AI app “remembers” me in its own silo. ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps. The deeper problem 1. Not portable – context is vendor-locked; nothing travels across tools. 2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance. 3. Not yours – your AI memory is sensitive first-party data, yet you have no control over where it lives or how it’s queried. Demo video: https://youtu.be/iANZ32dnK60 Repo: https://ift.tt/3S58tw7 What we built - CORE (Context Oriented Relational Engine): An open source, shareable knowledge graph (your memory vault) that lets any LLM (ChatGPT, Cursor, Claude, SOL, etc.) share and query the same persistent context. - Temporal + relational: Every fact gets a full version history (who, when, why), and nothing is wiped out when you change it—just timestamped and retired. - Local-first or hosted: Run it offline in Docker, or use our hosted instance. You choose which memories sync and which stay private. Try it - Hosted free tier (HN launch): https://core.heysol.ai - Docs: https://ift.tt/SyWLlmf https://ift.tt/3S58tw7 July 1, 2025 at 09:54PM

Show HN: Lifp – A Lisp Built on Bun https://ift.tt/Z5vArWB

Show HN: Lifp – A Lisp Built on Bun A silly summer break project where I played around with Bun, which I hadn't had the chance to yet. It's not super lisp-y, there's no car, no cdr, nor macros. It's a Lisp-Inspired Functional Programming language that ideally doesn't require a paradigm shift when you come from C-like languages. https://ift.tt/8M9fTlV July 1, 2025 at 08:04PM
