Scroll

A whole computer.

In a browser tab.

Meet Webuntu.

Boot it up

Webuntu

Real Linux kernel. Real desktop. Real `apt install`. Compiled to WebAssembly and restored from a snapshot, so it boots in seconds. Nobody asked for it. Everyone should try it.

x86-64

A real 64-bit PC, emulated instruction by instruction.

22.04

Ubuntu LTS. The actual one. Unmodified.

WASM

QEMU, compiled to WebAssembly.

Things to install. It's just a tab.

How it works

Four layers.
One impossible tab.

01 · The OS
Real Ubuntu.
An unmodified Ubuntu 22.04 disk image. The same operating system you'd install on a PC.
02 · The machine
An emulated PC.
QEMU emulates a complete 64-bit x86 computer: processor, memory, disks and display.
03 · The runtime
Compiled to WebAssembly.
The entire emulator runs as WebAssembly, so your browser becomes the computer.
04 · The trick
Instant boot.
It restores from a pre-booted snapshot, so you land at a live shell in seconds instead of waiting for a cold boot.

Webuntu

A real computer.
Without the computer.

Seconds,
not minutes.

Starts from a snapshot of an already-booted system, so you're at a live shell before you could have found the installer.

🐧

Actually Linux.

bash, apt, Python and a real filesystem. Do Linux things, for real.

🔒

Private by default.

Everything runs in your browser. Networking stays off until you turn it on.

💾

Saves your work.

Name an instance and its whole disk comes back on your next visit.

🌐

Optional internet.

DNS, TCP and HTTPS through a WebSocket relay. One toggle away.

🗂️

Many machines.

A scratchpad, a project box, something to break. Each one independent.

Everything else

Just as ridiculous.

Make a Leaf

Build a leaf. Gear it up. Watch nature win anyway. A cozy pixel-art game made in Godot.

I write code for fun, lead programming for an FTC robotics team, and build websites for real businesses. Mostly, I like doing things in a browser that people say can't be done in a browser.

FIRST Tech Challenge · 01

Design.

Every season brings a brand new game. It starts with a whiteboard, a lot of arguing, and a robot that only exists as lines.

FIRST Tech Challenge · 02

Build.

Metal, motors, wheels and wiring. The lines become a machine that actually weighs something.

FIRST Tech Challenge · 03

Program.

That's my part. As lead programmer for team #23562, I write the code that drives it, moves the arm and runs the autonomous period on its own.

FIRST Tech Challenge · 04

Compete.

Head-to-head matches against teams from across Hawaii. In three seasons Robo-Techs Hawaii went from new team to the top of the circuit.

I also build robots.

Lead programmer for Robo-Techs Hawaii. We design, build and program robots that compete head-to-head. In three seasons we went from new team to the top of the Hawaii circuit.
