Introduction An obscure quirk of the /proc/*/mem pseudofile is its “punch through” semantics. Writes performed through this file will succeed even if the destination virtual memory is marked unwritable. In fact, this behavior is intentional and actively used…

No, it doesn't cost Anthropic $5k per Claude Code user
The viral claim that Anthropic loses $5,000 per Claude Code subscriber doesn't survive basic scrutiny. Let's do the actual maths.

Show HN: Sub-millisecond VM sandboxes using CoW memory forking (Score: 154+ in 20 hours)
Link: https://readhacker.news/s/6PYP3
Comments: https://readhacker.news/c/6PYP3
I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM.
So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically.
That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits.
These are real KVM VMs, not containers: separate guest kernel, separate guest memory, separate page tables. When a VM writes to memory, it gets a private copy of that page.
The hard part was not CoW itself. The hard part was resuming the snapshotted VM correctly.
Rust, Apache 2.0.
