Self-hosting a NixOS VM on a Proxmox host which hosts a dozen homelab services from the *arr stack to grafana to macOS VMs.
All infrastructure is declared with Terraform and Ansible.
I reach into the homelab VLANs with @Tailscale and have Claude Code running around the clock

Spent last night grepping xAI's new Grok Build CLI!
Thankfully, every system prompt is a plain string constant! Build includes subagents, memory consolidation, plan mode, loop detection.
Happy to see the progress @xai

Built a spacecraft computer simulator from scratch!
Bare-metal C on ARM Cortex-M3, FreeRTOS task scheduling, and NASA's delay-tolerant networking stack, all running in QEMU and Docker.
No hardware required.

I added an agent to my CI pipeline that screenshots every UI state across three viewports on every PR push. Zero manual testing. Here's how it works

My blog links showed up as plain text on Twitter. No preview image. Just a naked URL.
14 minutes with Claude → every post now gets an OG image automatically.
Playwright screenshots the post. GitHub Actions commits the image. Zero manual work.

Setup is 5 lines of JSON:
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": ["@anthropic-ai/mcp-server-playwright", "--headless"]
}
}
}
GitHub issues become living test reports—anyone reviewing the PR sees exactly what was tested.

Running 6 Claude Code agents in parallel from my phone.
Here's my mobile dev setup:
My Claude Code mobile setup:
• Vultr VM ($0.29/hr, pay-per-use)
• Tailscale for secure access
• Termius mosh (survives network switches)
• Poke webhook for push notifications
• tmux for session persistenceKick off a task, pocket the phone, get notified when Claude needs input.

My Claude Code on-the-go setup:
- Vultr VM with 24GB running Ubuntu
- Termius for mobile terminal usage (it works quite well)
- Claude Code in yolo mode
- Poke for push notifications when Claude needs my attention (@interaction ❤️)
- tmux for session persistence (been running 6 Claude Code agents in parallel, tabbing pretty easily)
- Tailscale: SSH & Mosh only reachable from the subnet
All created from a single Claude Code session where I gave it my Vultr API key (through env var) and access to `gh`

We are saddened by the passing of Jim Lovell, commander of Apollo 13 and a four-time spaceflight veteran.
Lovell's life and work inspired millions. His courage under pressure helped forge our path to the Moon and beyond—a journey that continues today. go.nasa.gov/41tbrpq

U.S. labs keep finding *undocumented* cellular radios hidden inside some Chinese-made solar inverters & battery packs
Those radios give the gear a second, undocumented path to the internet. Global governments are reacting already: 🧵
