[Other] Show HN: Stop Claude Code from forgetting everything I got tired of Claude Code forgetting all my context every time I open a new session: set-up decisions, how I like my margins, decision history. etc.<p>We built a shared memory layer you can drop in as a Claude Code Skill. It’s basically a tiny memory DB with recall that remembers your sessions. Not magic. Not AGI. Just state.<p>Install in Claude Code:<p><pre><code> &#x2F;plugin marketplace add https:&#x2F;&#x2F;github.com&#x2F;mutable-state-inc&#x2F;ensue-skill &#x2F;plugin install ensue-memory # restart Claude Code </code></pre> What it does: (1) persists context between sessions (2) semantic &amp; temportal search (not just string grep). Basically git for your Claude brain<p>What it doesn’t do: - it won’t read your mind - it’s alpha; it might break if you throw a couch at it<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;mutable-state-inc&#x2F;ensue-skill" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mutable-state-inc&#x2F;ensue-skill</a><p>If you try it and it sucks, tell me why so I can fix it. Don&#x27;t be kind, tia

[Other] Obelisk 0.32: Cancellation, WebAPI, Postgres

[Other] Show HN: Zs3 – S3 server in ~1K lines of Zig, 250KB binary, zero dependencies Most S3 usage is PUT, GET, DELETE, LIST with basic auth. This does exactly that.<p>SigV4 auth, multipart uploads, range requests. Storage is just files on disk.<p>No versioning, no ACLs, no encryption. Use MinIO or AWS if you need those.

[DevOps] Show HN: Kuack – Run Kubernetes jobs in visitor browsers WebAssembly makes it possible to run serious computation in browsers. I wanted to see if we could treat browsers as Kubernetes workers.<p>Kuack is a Virtual Kubelet provider that schedules Kubernetes workloads to browser tabs. Visitors&#x27; browsers connect, report capacity, and become ephemeral workers. It looks like a regular Kubernetes node - same kubectl commands, same OCI images, same workflows. The difference is that pods execute in browsers instead of servers. With multi-platform OCI images, Kubernetes can fall back to regular nodes if no agents are available.<p>It&#x27;s designed for short-lived, stateless, CPU-heavy jobs: load testing from real networks, local data preprocessing, edge computing scenarios, machine learning tasks, etc.<p>Not a replacement for your cluster - just an extra option for workloads that benefit from browser execution.

Automatically send feedback for Claude Code to act on. Runs locally. Local plugin. No network requests. Plannotator runs entirely in your browser. Plans never leave your machine.

[Other] Show HN: Pion SCTP with RACK is 70% faster with 30% less latency SCTP is a low level protocol focused on reliable packet transmission. Unlike hopelessly flinging packets from one device to another, it makes sure that the packets are correct using CRC, removes duplicate packets, and allows for packets to be sent in any order.<p>Going into an established library, I thought that everything was already implemented and that there wasn&#x27;t anything to do until I went through the existing issues and organized all the tasks and decided on an order. Sean DuBois (<a href="https:&#x2F;&#x2F;github.com&#x2F;Sean-Der" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Sean-Der</a>), one of the co-creators and current maintainers of Pion, an open-source pure Go implementation of WebRTC (which uses SCTP), introduced me to a dissertation that was written about improving SCTP from 2021 (<a href="https:&#x2F;&#x2F;duepublico2.uni-due.de&#x2F;servlets&#x2F;MCRFileNodeServlet&#x2F;duepublico_derivate_00073893&#x2F;Diss_Weinrank.pdf" rel="nofollow">https:&#x2F;&#x2F;duepublico2.uni-due.de&#x2F;servlets&#x2F;MCRFileNodeServlet&#x2F;d...</a>). To my surprise, the features in it weren&#x27;t actually implemented yet, and generally went unused even though it depicted pretty big improvements. This came as a bit of a shock to me considering the countless companies and services that actively use Pion with millions of users on a daily basis.<p>This led to two things: 1) implement the feature (done by me) and 2) measure the performance (done by Joe Turki <a href="https:&#x2F;&#x2F;github.com&#x2F;JoeTurki" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;JoeTurki</a>). If you&#x27;re interested in reading more, please check out the blog post where we go over what SCTP is used for, how I improved it, and the effort that went into making such a large improvement possible.<p>This also marks a huge milestone for other companies and services that use SCTP as they can refer to the implementation in Pion for their own SCTP libraries including any real-time streaming platforms such as Microsoft Teams, Discord screen share, Twitch guest star, and many more!<p>For my personal background, please take a look at a comment below about what it was like for me to get started with open-source and my career related journeys. Thanks for reading!

[Other] Show HN: I built an open-source wallpaper gallery for GitHub repos Hey HN,<p>GitHub has hundreds of wallpaper repositories with thousands of images, but actually browsing them is painful. You either clone gigabytes locally or click through the file browser one by one.<p>So I built WALL·E Gallery. Use existing collections or Paste a repo URL→ instant gallery.<p>How it works: - Fetches repo tree via GitHub (no cloning) - Proxies thumbnails (~50KB instead of 10MB originals) - Works with private repos too (with GitHub token)<p>Infinite scroll, search, dark mode, mobile friendly, self-hostable. No accounts, no tracking.<p>Live: <a href="https:&#x2F;&#x2F;walle.theblank.club" rel="nofollow">https:&#x2F;&#x2F;walle.theblank.club</a> Source: <a href="https:&#x2F;&#x2F;github.com&#x2F;amitray007&#x2F;wall-e" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;amitray007&#x2F;wall-e</a><p>Do share your suggestions&#x2F;feedback. Also, I did find my desktop wallpaper from this.

[Other] Show HN: I created a tool to design and create foamcore inserts for boardgames As a holiday project to test out spec first development using Codex CLI, I ended up creating <a href="https:&#x2F;&#x2F;boxinsertdesigner.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;boxinsertdesigner.com&#x2F;</a><p>It lets you design a box insert in 2D and spits out a cutting list.<p>I&#x27;m looking for feedback, bugs, feature ideas etc and figured this would be a good place to find it :)
