[Other] Show HN: Equirect – a Rust VR video player This is almost entirely created by Claude, not me. I know some people aren&#x27;t into that. I was one of them 3 months ago. Since the beginning of the year I finally started getting more serious about trying out AI. The company I work for also had an AI week with lots of training. All I can say is I&#x27;m pretty blown away. My entire life feels like it changed over the last month from someone who mostly writes code to mostly someone that prompts AI to write code. And just for a tiny bit of context, I&#x27;m 60yrs old and have been coding since 1980.<p>I get all the concerns, and I review all AI code at work and most AI code for personal projects. This one in particular though, not so much. I get that&#x27;s frowned on but this is a small, limited scope, personal project. Not that I didn&#x27;t pay attention, Claude did do some things in strange ways and I asked it to fix them quite often. But, conversely, I have zero rust experience, zero OpenXR experience, zero wgpu expericence, next to zero relevant Windows experience.<p>I&#x27;m guessing I spent about ~30 hours in total prompting Claude for each step. I started with &quot;make a windows app that opens a window&quot;. Then I had it add wgpu and draw hello triangles. Then I had it add OpenXR and draw those triangles in VR. That actually took it some time as it tried to figure out how to connect a wgpu texture to the surface being drawn in OpenXR. It figured it out though, far far faster than I would have. I&#x27;d have tried to find a working example or given up.<p>I then sat on that for about a month and finally got back to it this weekend and zoomed through getting Claude to make it work. The only parts I did was make some programmer art icons.<p>I can post the prompts in the repo if anyone is interested, and assming I can find them.<p>Also in the last 2 weeks I&#x27;ve resurrected an old project that bit-rot. Claude got it all up to date, and fixed a bunch of bugs, and checked off a bunch of features I&#x27;d always wanted to add. I also had Claude write 2 libraries, a zip library, an rar decompression library, as well as refactor an existing zip decompression library to use some modern features. It&#x27;s been really fun! For those I read the code much more than I did for this one. Still, &quot;what I time to be alive&quot;!

[Database] Show HN: Rekal – Long-term memory for LLMs in a single SQLite file I got tired of repeating myself to my LLM every session. rekal is an MCP server that stores memories in SQLite and retrieves them with hybrid search (BM25 + vectors + recency decay). One file, local embeddings, no API keys.

[Database] Show HN: T4 – a versioned datastore with branching and time-travel (S3-backed) Hi HN,<p>I built t4, a datastore that stores its WAL and snapshots in S3.<p>Instead of traditional storage, it writes append-only segments to object storage and reconstructs state from checkpoints + WAL.<p>A side effect of this model is that the database becomes naturally versioned: you can restore any past state, branch from any point (with copy-on-write) and replay history<p>I started this as an experiment to replace etcd in Kubernetes, but it’s evolving into a general-purpose versioned state store.<p>Curious what people think about it and appreciate any feedback!

[CLI Tool] Show HN: Claudraband – Claude Code for the Power User Hello everyone.<p>Claudraband wraps a Claude Code TUI in a controlled terminal to enable extended workflows. It uses tmux for visible controlled sessions or xterm.js for headless sessions (a little slower), but everything is mediated by an actual Claude Code TUI.<p>One example of a workflow I use now is having my current Claude Code interrogate older sessions for certain decisions it made: <a href="https:&#x2F;&#x2F;github.com&#x2F;halfwhey&#x2F;claudraband?tab=readme-ov-file#self-interrogation" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;halfwhey&#x2F;claudraband?tab=readme-ov-file#s...</a><p>This project provides:<p>- Resumable non-interactive workflows. Essentially `claude -p` with session support: `cband continue &lt;session-id&gt; &#x27;what was the result of the research?&#x27;` - HTTP server to remotely control a Claude Code session: `cband serve --port 8123` - ACP server to use with alternative frontends such as Zed or Toad (<a href="https:&#x2F;&#x2F;github.com&#x2F;batrachianai&#x2F;toad" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;batrachianai&#x2F;toad</a>): `cband acp --model haiku`. - TypeScript library so you can integrate these workflows into your own application.<p>This exists cause I was using `tmux send-keys` heavily in a lot of my Claude Code workflows, but I wanted to streamline it.

[CLI Tool] Show HN: Waffle – Native macOS terminal that auto-tiles sessions into a grid Hi HN. I built Waffle because I kept ending up with 15 terminal windows scattered across three spaces with no idea what was running where.<p>Splitting&#x2F;merging in iTerm kind of works but it never felt intuitive to me.<p>With that in mind, I built something to suit my workflow:<p>Waffle is a native macOS terminal (Built on Miguel de Icaza&#x27;s SwiftTerm) that tiles your sessions into an auto-scaling grid automatically. 1 session is fullscreen, 2 is side by side, 4 is 2x2, 9 is 3x3. Open a terminal, it joins the grid. Close one, the grid rebalances. No splitting, no config.<p>I&#x27;ve been using it a lot recently and one thing I&#x27;ve found really useful is that sessions detect which repo they&#x27;re in and group accordingly. Each project gets a distinct colour. Cmd+[ and Cmd+] flip between groups. If you have three repos open across eight terminals, you can filter to just one project&#x27;s sessions instantly. Also, no accidentally closing a window with CMD-W as it gives you a confirmation and requires a second CMD-W to close.<p>Honestly, if you live in tmux, this probably isn&#x27;t for you but it&#x27;s really helped to speed up my workflow.<p>Other things: It comes with a handful of themes (and has support for iTerm themes), bundled JetBrains mono, has keyboard shortcuts for everything. Free, no account, opt-in analytics only. macOS 14+.<p>There&#x27;s a demo on the landing page if you want to see it in action.

[Other] Show HN: I rebuilt a 2000s browser strategy game on Cloudflare's edge I grew up in Germany in the early 2000s playing a browser game called Inselkampf. You built up an island, mined gold and stone, cut down trees for wood, raised armies, sent fleets across an ocean grid, joined alliances and got betrayed by them. Same genre as OGame or Travian. It shut down in 2014 and I never found anything that replaced that feeling of checking in before school to see if your fleet had arrived and your alliance was still alive.<p>I finally built the version I wanted to play. Kampfinsel is live at kampfinsel.com right now with real players on it. It&#x27;s not a straight copy of the old game. I gave it its own world. No magic, no gunpowder – just ballistas, fire pots, and slow ships crossing huge distances. Three resources: gold, stone, wood. Travel between islands takes hours, not seconds. It&#x27;s slow on purpose.<p>The whole thing runs on Cloudflare&#x27;s edge. Workers for the game logic and API, D1 for the database, KV for sessions and caching, R2 for assets and Durable Objects for per-island state and the tick system (fleet arrivals, combat, resource generation). There&#x27;s no origin server at all. Making a stateful multiplayer game work inside Workers&#x27; CPU limits and D1&#x27;s consistency model meant some non-obvious choices: resources are calculated on-read from timestamps instead of being ticked into the database, fleet movements live in Durable Object alarms and combat writes are batched. This helped me a lot!<p>The look is intentionally rough and text-heavy (Hi HN!): server-rendered HTML, tables, a parchment color palette, Unicode icons, no frontend framework, no build step. The only JavaScript is for countdown timers and auto-refresh. I wanted it to feel the way I remember these games looking, not how they actually looked. Honestly, it looks a lot like HN itself - tables, monospace, no chrome. If you like how this site looks, you&#x27;ll probably feel at home.<p>No signup wall, no premium currency, no pay-to-win. Feedback very welcome, especially from anyone who played this kind of game back in the day or has opinions on running stateful stuff on Workers + D1 + Durable Objects. I&#x27;ll be around for the next few hours.
