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.
01 · xPON Freedom / 光回線に自由を
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.
Figures as of November 2026, from GitHub and openpon.org.

Lead
Open firmware for Realtek GPON sticks. Broad OLT compatibility, VEIP support, link speed unbound from 1GbE to 2.5GbE, and metrics exported straight to Prometheus and Grafana.
Founder
A vendor-neutral, volunteer effort for open, interoperable and privacy-respecting passive optical networking. One front door for the firmware, the hardware, the countries it works in and the people behind it.

Internet Friendly Media Encoder
x264, x265, x266 and AV1 GUI encoder where every codec is a drop-in plugin you can update yourself. Remuxes, merges streams, keeps subtitles and fonts, and supports NVENC, Quick Sync and AMF. Windows and Linux.

Strongest first.
C#
Where most of my desktop software lives.
IFME, FFmpegDotNet, SMF Converter, KageMusic
Python
Tooling, automation and the machine learning side.
Stable Diffusion and Dreambooth training, RVC voice models
C
Close to the hardware — drivers and USB programmers.
libusb341, the SFP-Master and IMSProg Windows ports
Java
Fourth on the list, but on the list.
I speak Malay, English and 日本語.
04 · Network / ネットワーク
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.
