Zixing Liu | Membership Application

I, Zixing Liu, apply for core-dev.

Name Zixing Liu
Launchpad Page Zixing Liu in Launchpad
Wiki Page https://wiki.ubuntu.com/liushuyu-011

I am applying because:

  • I’d like to eliminate delays in getting my work sponsored.
  • I’d like to reduce the burden on my sponsors.

Who I am

I am a software engineer from Canada working for Canonical Canada. While this is my first job, I have some prior experience working on software projects during high school and university for various open-source projects.

I studied Computer Science and Statistics at the University of Alberta in Canada.

My Ubuntu story

In high school (circa 2013), I learned the world beyond Windows and OS X (later renamed macOS).
The first version I installed on my device was Lucid (12.04), and then I discovered I couldn’t use wireless anymore (later, I learned this was because I had a Broadcom BCM4312 card).
Then, I started distro-hopping until university, where I finally settled on Ubuntu 18.04 for ordinary devices and another non-mainstream Linux distro for more exotic devices.

My involvement

As a member of the Foundations team, whose responsibility is mainly to the Rust toolchain, my main focus is the Rust micro-ecosystem within Ubuntu and Debian.

However, due to the nature of my work, I am still working on a larger scope of system packages in Ubuntu. This might include “other languages” toolchains like Node.js and D language.

In somewhat recent times, I also helped the Ubuntu/Debian work through the armhf time_t transition and the xz-utils-related archive rebuild/clean-up.

>> List of other Ubuntu contributions

Ubuntu-related Upstream work

The following listing does not include patches forwarded to Debian and only includes accepted work.

Areas of work

  • Update and fix Rust toolchains in Ubuntu and (sometimes) upstream.
  • Attending +1 maintenance shifts.
  • Looking for ways to improve Rust developer experiences on Ubuntu.
  • (Sometimes) maintain other toolchains for which no particular Ubuntu team is responsible.

Things I could do better

  • Focus on the details and avoid minor mistakes
  • Get to know the wider Ubuntu and Linux community
  • Help more upstream projects to have better software delivered on Ubuntu (especially Rust projects)

Plans for the future


  • Help Rust-GCC to at least compile the standard hello world program (as in the newcomer tutorial)
  • Help more people in the Ubuntu community to know about Rust
  • Help more Rust developers (Rustaceans) to know Ubuntu and clear up the misunderstandings
  • Help more frontend developers understand why Rust is a good fit for JavaScript/WASM tooling
  • Help grow other safe(r) system language toolchains (e.g. Ada, D, Swift and Zig) within Ubuntu (and Debian).

What I like least in Ubuntu

  • Localization/CJK support was and is still a huge disaster. When I finished installing 12.04, the first thing I discovered (aside from WiFi being unavailable) was that the Chinese input method editor was not working. Fast-forward 10 years, and the input method story with Wayland is now even worse.
  • Launchpad UI/UX is problematic, especially on a HiDPI screen. With most desktop/laptop devices using high-resolution screens, the texts are so small that I must manually set the scaling (not to mention the mobile experience is non-existent).
  • Too few people participating in the development. Maybe it’s a general thing about all the Linux distributions, but if you look at #ubuntu-devel IRC, the people talking there are usually limited to a handful that you will memorize all within a day.


Impressive contributions towards Ubuntu.
Especially being on the Foundations team since 2023.
