Show HN: SQLite for Rivet Actors – one database per agent, tenant, or document https://ift.tt/6KcCJdy

Show HN: SQLite for Rivet Actors – one database per agent, tenant, or document Hey HN! We posted Rivet Actors here previously [1] as an open-source alternative to Cloudflare Durable Objects. Today we've released SQLite storage for actors (Apache 2.0). Every actor gets its own SQLite database. This means you can have millions of independent databases: one for each agent, tenant, user, or document. Useful for: - AI agents: per-agent DB for message history, state, embeddings - Multi-tenant SaaS: real per-tenant isolation, no RLS hacks - Collaborative documents: each document gets its own database with built-in multiplayer - Per-user databases: isolated, scales horizontally, runs at the edge The idea of splitting data per entity isn't new: Cassandra and DynamoDB use partition keys to scale horizontally, but you're stuck with rigid schemas ("single-table design" [3]), limited queries, and painful migrations. SQLite per entity gives you the same scalability without thos...

Show HN: Soma, a local-first AI OS with 178 cognitive modules and P2P learning https://ift.tt/zQERvaw

Show HN: Soma, a local-first AI OS with 178 cognitive modules and P2P learning Local-first AI operating system — 178 cognitive modules, persistent memory, multi-model reasoning, P2P Graymatter Network. I can no longer develop this AI as it has gotten to be out of my knowledge range so I figured I would give her to the public, she should be a good base for any future AI development even going towards ASI! https://ift.tt/zax56Hy February 28, 2026 at 10:41PM

Show HN: Unfudged – version every change between commits - local-first https://ift.tt/frwAq7O

Show HN: Unfudged – version every change between commits - local-first I built unf after I pasted a prompt into the wrong agent terminal and it overwrote hours of hand-edits across a handful of files. Git couldn't help because I hadn't finished/committed my in progress work. I wanted something that recorded every save automatically so I could rewind to any point in time. I wanted to make it difficult for an agent to permanently screw anything up, even with an errant rm -rf unf is a background daemon that watches directories you choose (via CLI) and snapshots every text file on save. It stores file contents in an object store, tracks metadata in SQLite, and gives you a CLI to query and restore any version. The install includes a UI, as well to explore the history through time. The tool skips binaries and respects `.gitignore` if one exists. The interface borrows from git so it should feel familiar: unf log , unf diff , unf restore . I say "UN-EF" vs U.N.F, but that...

Show HN: Goatpad https://ift.tt/XnsZ9IO

Show HN: Goatpad Think Notepad, but with goats! It started as a joke with some friends and then I realized this was the perfect project to see far I could get with Claude without opening my IDE (which I'd wanted to try for a while with a small app) I was pretty shocked to find that I only needed to manually intervene for: 1. Initializing the repo 2. Generating sprites - I tried a few image gen tools, but couldn't get a non-messy looking sprite to generate to my liking. I ended up using some free goat sprites I found instead (credited in the About section) 3. Uploading images/sprite sheets (raw claude code can't do this for some reason?) 4. DNS stuff Aside from agents timing out/hanging periodically and some style hand holding, it was pretty straightforward and consistently accurate natural language coding end to end. I suspect this is in large part to replicating an existing, well documented style of app, but it was good practice for other projects I have planned. The goats...

Show HN: Beehive – Multi-Workspace Agent Orchestrator https://ift.tt/wJD3ryv

Show HN: Beehive – Multi-Workspace Agent Orchestrator hey hn, i built beehive for myself mostly. it has gotten to the point where my work consists in supervising oc or cc labor at tasks for multiple issues in parallel. my set up used to be zellij with a couple tabs, each tab working in a separate dir and it was a pain to manage all that. i know i could use git worktrees but they're kind of complicated, if you don't know how to use them it is easy to mess up, and i just prefer letting agents run in separate dirs with their own .git and not risk it. while i like zellij and use it inside beehive, i dont like the tabs and i forget where i am half the time. beehive is a way for me to abstract that away. the heuristic is simple - hives are repos, so you basically have a bunch of hives which correspond to repos you work out of. each hive can have many combs. a comb is a dir with the copy of the repo you're working on. fully isolated, standalone, no shared .git. so for work or for ...

Show HN: Live iOS 26.3 exploit detection (CVE-2026-20700) – Multi-region C2 https://ift.tt/OrSAehv

Show HN: Live iOS 26.3 exploit detection (CVE-2026-20700) – Multi-region C2 Public release of *ZombieHunter*, a forensics tool detecting live exploitation of CVE‑2026‑20700 (dyld memory corruption) in iOS 26.3. Analysis of sysdiagnose archives shows identical exploit shells showing different C2 endpoints: US Device 1 → 83.116.114.97 (EU/US) US Device 2 → 101.99.111.110 (CN) The rogue dyld_shared_cache slice triggers overflow via malformed `mappings_count`, executes shellcode (BL #0x15cd), and applies an AMFI bypass (`DYLD_AMFI_FAKE`) enabling unsigned code persistence. Apple PSIRT + CISA were notified; public disclosure follows. Sample: https://drive.google.com/file/d/1rYNGtKBMb34FQT4zLExI51sdAYR... SHA256 artifact: ac746508938646c0cfae3f1d33f15bae718efbc7f0972426c41555e02e6f9770 Usage: `python3 zombie_auditor.py sysdiagnose_xxx.tar.gz` (Needs capstone) Reproducible PoC confirms CVE‑2026‑20700 bypass, AMFI neutralization, and live C2 connectivity in production iOS 26.3. https://ift.tt/...
