[Other] Show HN: CSS generator for a high-def glass effect There are lots of glassmorphism generators out there, but I wanted to push the effect further! This project is the result of months of experimenting with CSS property layering and battling browser quirks.<p>Cross-browser compatibility is actually the reason I rely on ::before and ::after pseudo-elements to build up the effect. Move the color&#x2F;opacity to the main element, and you’ll get weird color bleed on the corners in Chrome. Move the texture, and it muddles the bevel’s specular highlight. Move the bevel, and it gets blurred out by the backdrop-filter. And so on!<p>Layers include: * Adjustable blur, brightness, and saturation (backdrop-filter) * Subtle translucent texture * Faux 3D bevel (using box-shadows, not an outline)<p>Glassmorphism is rather heavy on resources, so it’s best used as an accent and avoided on wide desktop elements. Should be compatible with recent versions of Chrome, Safari, and Firefox (desktop and mobile). If you spot bugs or rendering glitches, I’d love to know!<p>Side note: this is an early preview of a framework-agnostic glass SCSS&#x2F;component library I’m building.

[Other] Show HN: I made Logic gates using CSS if() function

[CLI Tool] Show HN: Opasm, an Assembly REPL This is a fun repl for running arbitrary assembly commands, right now it supports x86, X86_64, arm, aarch64, but there&#x27;s not a big reason that I can&#x27;t add support for other qemu&#x2F;capstone&#x2F;unicorn&#x2F; keystone supported architectures, just have to do it

[Other] Show HN: Terminal in Browser I wrote a small golang project to render terminal on browser. It is a single binary that can be deployed on any server and you can access the terminal over web.

[Other] 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.<p>The deeper problem<p>1. Not portable – context is vendor-locked; nothing travels across tools.<p>2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance.<p>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.<p>Demo video: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;iANZ32dnK60" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;iANZ32dnK60</a><p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;RedPlanetHQ&#x2F;core">https:&#x2F;&#x2F;github.com&#x2F;RedPlanetHQ&#x2F;core</a><p>What we built<p>- 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.<p>- 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.<p>- Local-first or hosted: Run it offline in Docker, or use our hosted instance.

[Code Quality] Show HN: Flint – Write code your way while ensuring remote consistency I just released my biggest project yet: Flint, a language-agnostic Git wrapper that lets developers code using their own formatting preferences locally, while automatically enforcing the project&#x27;s style on push.<p>No more fighting over tabs vs spaces or dealing with noisy diffs.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;capsulescodes&#x2F;flint">https:&#x2F;&#x2F;github.com&#x2F;capsulescodes&#x2F;flint</a> Documentation: <a href="https:&#x2F;&#x2F;flintable.com&#x2F;docs&#x2F;flint&#x2F;" rel="nofollow">https:&#x2F;&#x2F;flintable.com&#x2F;docs&#x2F;flint&#x2F;</a> Article: <a href="https:&#x2F;&#x2F;capsules.codes&#x2F;en&#x2F;blog&#x2F;flintable&#x2F;en-flintable-introducing-flint" rel="nofollow">https:&#x2F;&#x2F;capsules.codes&#x2F;en&#x2F;blog&#x2F;flintable&#x2F;en-flintable-introd...</a>

[Other] Show HN: I built the tool I wished existed for moving Stripe between countries In late 2024, I had to set up a new Stripe account because I incorporated my company in a different country. Turns out it&#x27;s not as simple as just changing the country in a dropdown, you have to start from scratch.<p>I had hundreds of users and using Stripe&#x27;s dashboard to add all of the products, prices, coupons and subscriptions manually would take ages. I contacted a couple of services that help with this kind of migration, but their quotes were way over my budget. My next option was to use Stripe&#x27;s API, which is very powerful but also very complicated. I&#x27;m a designer who can code, but I didn&#x27;t feel confident doing it alone, so I asked a friend, an experienced developer, to help.<p>It proved to be quite challenging, with many details and caveats we had to learn as we went. What we thought would take a couple of days took us a week.<p>After this experience, we teamed up and built <a href="https:&#x2F;&#x2F;stripemove.com" rel="nofollow">https:&#x2F;&#x2F;stripemove.com</a>, a tool that guides you through this whole process, explaining and automating that hard week we went through. It handles the technical complexity while keeping your business running. Customers keep paying on your old account while everything transfers in parallel, then you flip the switch when ready.<p>It&#x27;s a very niche tool, built for founders who need to change their company location for personal or business reasons. For entrepreneurs buying companies established in other countries. For people in the same situation I was in a few months ago. Basically the tool I wished existed, and for a fair price. Designed to get you through this inconvenient process and back as soon as possible on growing your business.<p>Would love to hear from anyone who&#x27;s dealt with similar Stripe migrations. What was your biggest pain point?

[Other] Show HN: Jobs by Referral: Find jobs in your LinkedIn network I have some friends who were laid off and are on the job hunt. We were all quite surprised to learn that LinkedIn does not have a &quot;view jobs only at companies where I have connections&quot;, so I built <a href="https:&#x2F;&#x2F;jobsbyreferral.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;jobsbyreferral.com&#x2F;</a><p>It&#x27;s powered by <a href="https:&#x2F;&#x2F;rapidapi.com&#x2F;letscrape-6bRBa3QguO5&#x2F;api&#x2F;jsearch" rel="nofollow">https:&#x2F;&#x2F;rapidapi.com&#x2F;letscrape-6bRBa3QguO5&#x2F;api&#x2F;jsearch</a>, which is a little pricey, so I&#x27;m trying to decide whether to put more effort into the project (I&#x27;d have to charge _something_ to offset the costs).

[Other] Show HN: A cross-platform terminal emulator written in Java It&#x27;s based on the jediterm library developed for IDEs, but it can also be put to work as a standalone terminal emulator with tabs. The library has been around for more than 10 years, but I don&#x27;t think anyone made a terminal emulator app from it?
