PocketTerm

What it does

Hi PH! I'm Edgar. I built PocketTerm because real VMs are heavy and beginners shouldn't have to manage SSH keys just to learn grep. This is a 100% browser-side simulation with a persistent filesystem. Use it to practice, test scripts, or safely run rm -rf / just to see the world burn (it's protected, don't worry).

  Sub-millisecond VM sandboxes using CoW memory forkingMar 2026 · github.com · ▲311

  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…

  Hi one and all. I've created an encrypted personal organizer I wish to share with you all. I know.... you are sighing and thinking "Oh! No! not another one". doogiePIM is different in that it's built by the same coder that created one of the very first PIMs that came out around 18+ years ago and creator of TexNotes way back then (it was actually called Scribillo. Wow, I feel old). The original PIM was sold then abandoned by GemX Software and that made me feel really bad. So, I obtained the full code and started to build a far better version of the information manager. One that will…
