• PHP: I mainly worked with projects related to PocketMine-MP during secondary school. Since PHP was unfortunately selected as the language for PocketMine-MP, the related projects used PHP as well.
• Rust: Most of my personal projects are in Rust since 2019. I also engage on the rust language community discord regularly.
• Go: I have been working on Kubernetes-related projects in ByteDance, where Go is the first class language (also quite unfortunately).

• jq: I use jq for all scripting only involving deterministic computation.
• Python: I use Python as my calculator app and makeshift plotting tool.

• Linux: i 👏 use 👏 arch 👏 btw 👏 (with GNOME).
• Bash: My login shell is Bash.
• Neovim: My setup is here.
• And I ssh over tmux over mosh over iTerm2 when I am stuck with a MacBook.
• Git: I always prefer merge commits over rebasing. Force-pushing branches that have been checked out by other people is a crime.

Just some stickers like everyone else does because why not

I have started jotting down some of my weird opinions in the wiki of this personal repo.

• I have started a lot of open-source projects for personal interest, but many are incomplete because of lack of time and financial support. Incomplete projects are marked as ⏳.
• Each section is sorted in descending order of my personal affection for the projects. Projects beyond a certain threshold of personal affection are not listed here.
• Only projects where I am/was a maintainer are listed here. Search on GitHub for a full list of my external contributions.

• await-generator, a PHP library that enables async/await pattern.
• thisrc, a PHP extension that observes the refcount of the $this object without inducing side effects

• portrait, a Rust proc-macro framework to write trait-aware proc-macro attributes such as impl-by-delegation.
• wordvec, a Rust library providing a thin and small vector with only 1/3 memory footprint of smallvec and comparable performance.
• include-flate, a Rust macro for attaching constants as deflated strings in the executable.
• dirmod, a Rust macro to smartly detect modules to include.
• phar.rs, a Rust library for the PHAR (PHp ARchive) format. Also includes a WASM app and a CLI command for phar manipulation.
• xylem, a Rust framework for statetul type conversion (a post-deserialize processing stage).

I have also created numerous tiny libraries in Rust, but those generally have very ad-hoc purposes and are not known to have any real users other than myself. Check crates.io for a full list of my crayon crates.

• rwlock-promise, a JavaScript library that implements mutually-exclusive and shared-exclusive locks with a Promise API

• enclavlow, my final year project that performs Java flow analysis to verify SGX data security.

These projects (and only these projects) are related to my work at ByteDance.

• Kelemetry, an observability tool to provide global control plane tracing for Kubernetes.
• Podseidon, a Kubernetes webhook to protect pod deletion in multi-cluster microservices.
• KubeAdmiral, a multi-cluster orchestrator and scheduler for Kubernetes.
• KubeZoo, a lightweight multi-tenancy solution for Kubernetes.

• PocketMine-MP, a reverse-engineered Minecraft server software.
  • PocketMine-MP has a huge ecosystem of plugins, and most of my work in earlier years were related to developing tools and cohesion of the ecosystem, such as dependency management, build tools and common-dependency APIs.
  • PocketMine-MP is an ancient project started in 2012. Some of my contributions include introducing modern tools and paradigms to the project.
• ⏳ dynec, an ECS library that focuses on type safety and optimized for specific scenarios.
• ⏳ Traffloat, a logistics simulation game written in Rust.
• ⏳ omniatc, an open-source air traffic control simulator game in Rust.

I was a member of the HKU Robocon Team.

I developed these small apps for personal use over the years.

• AndTransfer, a simple Android app that shares files to any transfer.sh server.
• Mentamatics, an app for practising mental arithmetic calculation.
• MySQLClientCompact, a small MySQL browser.

• bthint, to tell people to ``` their code blocks when asking for help.
• orbs.bot, a fan project that reverse engineers the API of the webgame orbs.it and mirrors live games

• StackOverflow/StackExchange
• Keybase
• Discord

More about myself:

• I started coding in 2013, previously known as @PEMapModder, but I stopped using that account in an unsuccessful attempt to detox from my programming addiction in 2016 (which ended up to be a Hydra).
• I studied stuff related to computer science, statistics and mathematics in the University of Hong Kong, but I never got good grades in mathematics and never even liked statistics, so just forget it.
• I have been working in ByteDance since 2021 on Kubernetes and scheduling.

Interests:

• Please nerd snipe me with content related to aviation and classical music.
• I don't like working on problems without a deterministic solution. Thus, none of my projects are related to statistical learning, AI or LLMs.
• I never monetize my personal projects. I never work on anything directly related to e-commerce, advertisement. I will never work on anything directly related financial investment and trading.
