A developer started KiviDB in February to learn Rust after hitting GC pauses and out-of-memory crashes with Dragonfly at work. He used AI a lot but made the design decisions himself, based on tests Claude picked from his history of troubleshooting sessions. It speaks RESP2 and RESP3, shards the keyspace across threads and uses io_uring on Linux.
A builder made Cubicles because he did not want his agent living on his laptop with his files, accounts and home network. Each agent gets a full Ubuntu desktop in the cloud with OpenClaw and Hermes Agent preinstalled, stays on 24/7, and you can watch it live from any browser.
A developer built an app that takes any idea, researches it, checks feasibility and creates a working concept using several sub-agents, running cheaply on his own VPS with SearXNG search and Codex.
A practical guide to running coding agents in named, detachable tmux sessions that survive a closed terminal or dropped SSH link. It starts with the built-in claude --worktree --tmux, then shows send-keys to type into any agent from a script and capture-pane to read its output back, and where tmux stops being enough.
A builder had Claude Code inspect the Android TV box from his TV provider from a prompt and one photo, install a Linux shell built for its chip, add a wake lock and battery whitelist so Android cannot kill the agent, and wire the agent to his own Telegram bot with no open ports.
Tired of juggling tmux, SSH sessions and coding agents that each work in their own corner, a developer built kraal, a terminal multiplexer that knows about both your servers and agents such as Claude Code, Codex and Gemini CLI.
For people running agents in tmux and checking on them with Termius and Tailscale, Tenax lets you sign in and see your sessions without SSH keys or a VPN. It pings you when an agent needs you or finishes.
MeshXFS is an open-source clustered filesystem built on XFS. The original XFS code came from human developers; its author Stephen Shoecraft says AI wrote all the additions needed to make it clustered, and he did not review that code.
Linus Torvalds let Claude Code fix a performance bottleneck in the Linux page cache. Kernel reviewers then found a race condition in the change, which shows why AI patches to core code still need careful human review.
A builder making his own JARVIS had Grok write the code for an MCP server on his TV, so Grok Bot can read the screen and drive it like he would. Next he plans a Raspberry Pi that runs the whole house.
Shipback deploys a folder to any SFTP host (cPanel, Plesk, DirectAdmin or a VPS) and backs up every file it overwrites first. One command restores the previous files, it refuses to undo over a live edit, and its MCP server has no switch to skip the backup, so Claude Code, Cursor or any MCP client can deploy safely.
LinPad OS brings Linux to the iPad with git, Python, Node.js, VS Code and a terminal, and Claude Code is listed in its store.
A builder argues the provider dashboards are not real token statistics and routes every agent, harness and app through a self-hosted LLM proxy instead. One endpoint covers many providers and models, logs which key called which model from which client and when, and hands out virtual API keys so the main key is not pasted into every tool.
His TV had become unbearably slow, so he spent an afternoon with Claude Code connected to it. It disabled 25 preinstalled bloat apps, replaced the 192 MB stock launcher with a custom 83 MB one and added rotating wallpapers.
A retro fan plugged a Raspberry Pi into an old TV and pointed Claude at it. It now runs his own cable network with internet streaming, live weather and movies from his NAS, plus a phone remote he built.
A user's parents had an old Android TV that was slow and full of ads. Claude cleaned it up and built them a new home screen from scratch; he shared the exact steps and the prompt to do it on your own TV.
SpaceApp is a self-hosted workspace that runs AI coding CLIs side by side in persistent rooms: OpenCode, Codex, Claude Code, Gemini, Qwen, Kimi, Grok and DeepSeek, each in its own pane on your own machine.
Rather than pay for another AI subscription, Kyle Walker set up OpenClaw agents on the VPS he already uses for automations. They talk to him and to each other as Slack apps.
A builder vibe coded a setup using Claude Code's self-hosted runners feature plus Tailscale, so the same dev environment works seamlessly across laptop, web and mobile. The box also runs Paper so the whole team can design on it.
A user who was not sure what to do with Hermes Agent asked it to secure a VPS. A few prompts and a public key later it had set up a WireGuard tunnel, limited SSH to WireGuard peers and blocked public SSH in one shot.
A self-hoster cancelled their Hermes Agent VPS because it mostly sat idle; now Grok Bot spins Hermes up on its own computer when it is needed.
The author combined Linux, Hermes Agent, a ChatGPT subscription and Signal into a personal Jarvis with separate chats per job and a restricted bot the whole family can use.
DEsk is a Wayland desktop environment for Linux with a skeuomorphic look. The author decided what it should be and how it should look and tested it on real machines, while much of the code and documentation was written by Claude under his direction.
A GNOME developer wanted to scan his late mother's film negatives on a Plustek scanner that Linux no longer supported. He had Claude Code set up a Windows virtual machine with the scanner passed through, capture the USB traffic of the vendor driver, and compare it with Linux until scans worked. He then had Claude turn the scripts into a reusable hardware reverse-engineering harness.
