Every Listing Is a Stranger's Agent: Isolating a Marketplace
You launched an agent marketplace. Every listing is code a stranger wrote, driven by a model, calling tools you didn't write, against your customers' credentials. Here's the isolation shape that survives that.
Hostile and Precious: Per-Case microVMs for Forensics and E-Discovery
The PST you have to open is full of the malware that caused the incident, and you are also legally obligated not to change a single byte of it. One VM per matter is the shape that satisfies both.
One Demo per Prospect: Sales Environments You Can Throw Away
Two AEs demo at the same time and one of them watches their data change live on the call. The fix is structural: bake one golden demo — app plus seeded database — and fork it per prospect, so "give me a clean environment" is a button and not a ticket.
Run the PoC: Vulnerability Triage in Disposable microVMs
A bug bounty report is a stranger's script plus a claim, and the only way to check the claim is to run the script — against a system you have deliberately made vulnerable. Here is the per-report microVM shape that makes that a routine Tuesday instead of an incident.
Your Firecracker Snapshot Restore Failed: A Field Guide
A restore either works in tens of milliseconds or fails with an error that tells you almost nothing. Here are the seven classes of Firecracker snapshot restore failure, what each looks like, and how to bisect your way to the real cause.
You Ship the Kernel: Firecracker Guest 5.10 vs 6.1
In a microVM, the guest kernel is a build artifact of your platform, not something a distro picks for you. Here's the honest 5.10 vs 6.1 trade — and the snapshot re-bake nobody budgets for.
Should You Compress Firecracker Memory Snapshots?
Compression looks like free money when your snapshot bucket is measured in terabytes. Then you discover that a compressed stream has no byte N — and your lazy 49ms restore turns into reading four gigabytes you were never going to touch.
Best n8n Hosting Platforms in 2026: A Self-Hoster's Guide
You've decided to self-host n8n. Now you have to pick infrastructure for a stateful, always-on, long-running service that also happens to execute arbitrary JavaScript for a living.
Best LangGraph Deployment Platforms in 2026
Your graph works in the notebook. Now it has to survive a deploy, a crash, and a human who takes three days to approve step 7. Here are the requirements that eliminate most platforms, and the seven that are left.
Firecracker vs Proxmox: a VMM Is Not a Platform
Proxmox VE manages VMs. Firecracker runs one. The comparison is a layer mismatch — but the question underneath it is real, and the answer usually comes down to whether your guests are pets or cattle.
The best Strapi hosting platforms in 2026
Strapi is four hosting problems in a trenchcoat: a long-running Node server, a real database, an uploads directory that must survive deploys, and an admin panel rebuilt at deploy time. Skip any one and it breaks in a specific, predictable way.
The best MCP server hosting platforms in 2026
A remote MCP server is not a REST API with a different schema. It holds session state, streams server-to-client messages over a connection that stays open, and runs tool calls that some model decided on. Most hosting advice ignores all three.
