ひとは☆もえ Anime Programming

I'm an otaku from Malaysia who writes code, mods games and takes apart the fibre box your ISP would rather you left alone. I lead the RTL960x xPON hacking effort, started the Open PON Foundation, and build IFME — a video encoder for people who keep their subtitles.

The box at the end of your fibre should be yours.

For most subscribers, fibre ends in a small white box the ISP hands over. You did not choose it, you cannot audit what runs on it, and when it fails you wait for a replacement.

The research began in 2020, the year the pandemic kept developers and hackers at home, and went public in 2021: documenting and reverse engineering Realtek RTL960x GPON sticks, so an SFP module in your own router can stand in for that box. What started as one repository is now a worldwide effort with its own firmware, its own tooling and a foundation behind it.

  1. Operator OLT The ISP's end of the fibre, in the exchange.
  2. Shared Splitter One fibre, split passively between you and your neighbours.
  3. Yours ONT The box on your wall. Closed, locked, rented — this is the part we open.
  4. Yours Router Everything from here to your LAN, on hardware you chose.

What I like

I speak Malay, English and 日本語.

04 · Network

From homelab to real infrastructure

I am most at home on MikroTik. A NAS built from a friend's spare parts grew into a server in a Cyberjaya data centre that runs ΕΛΠΙΣ DNS, game servers and more.

No school or university teaches this. Understanding BGP, and the experience that comes with it, is the most expensive lesson there is.
