Liang-Psych/README.md

Hi, I'm Liang Xu

Data Science × Systems — R/Python analyst by day, Linux forensics enthusiast by night. I run a single-node data workbench (Positron + RStudio Server, Presto/Doris behind MCP) and occasionally send fixes upstream.

Upstream work

  • posit-dev/positron#16167 — filed: stale kernel-supervisor tombstones from Linux TID collisions + missing removeByPid on shutdown errors
  • posit-dev/positron#16176 — fix: socket + /proc comm guards, registry cleanup on ENOENT/ECONNREFUSED, unit tests (adopted upstream as #16224)

Daily drivers

R Python TypeScript Docker Linux

Currently

  • Single-user data platform: Positron/RStudio, Pixi envs, commercial ODBC (Oracle/MySQL/Spark), MCP data gateways
  • Interests: kernel lifecycle forensics, containerized data science, AI-assisted analysis
  • Languages: R · Python · TypeScript · Rust (reading) · SQL
  • Glue: Docker · Linux · Git · ODBC · MCP
