Hi 👋

I am Oleg Iarygin, a master of Computer Science who builds up a portfolio here and resolves use case pains in other projects. Also, I have a miraculous ability to use stuff in unintended ways without being aware of it, so I constantly meet lags and crashes.

  • 🔭 I’m currently working on making the Python repository more convenient from novice standpoint.
  • 🌱 I’m currently learning Open CASCADE Technology library (aka OCCT).
  • 👯 I’m looking to collaborate on old python/cpython issues to reduce the issue count below 999.
  • 💬 Ask me about mitigation of C quirks, how to port a static site to an ad-hoc Python generator, and how to preserve sanity in the process.
  • 📫 How to reach me: or VK (the PM is open for everyone).
  • 😄 Pronouns: He/Him.
  • ⚡ Fun fact: I’m a fan of Unreal Gold.

Pro tips:

  • 🧼 Keep hands sanitized after each rebase with git filter-branch --env-filter "GIT_COMMITTER_DATE=$GIT_AUTHOR_DATE" -f HEAD~howmanycommits..HEAD.
  • :godmode: Older versions of Visual Studio (2019, 2017, 2015, and 2013) can be downloaded at

I use the Pomodoro technique:

What I Am Working On Now

Priority Tasks
⛔ Blocker arhadthedev#47: Sort out data hoarding piles on my drives and in my clouds (I'm totally out of available disc space, both on internal, external drives and cloud storages; mere megabytes do not count)
⚠ High Improving python/cpython GitHub-related stuff to make life of all contributors easier. See my project #5 for details
🛠️ Medium Finalizing my own aged pull requests. See a list sorted by creation date for details
🧘🏼‍♀️ Background Working on merging ancient but still worthy PRs to reduce the total python/cpython PR count below 1k. See my project #9 for details

  • Maintenance
    • (sources), a centralized list of per-version support status for 136 popular programs, services, and OSes

Offline tools

  • When CPython developers need to remove some function or class from Python, they do a code search for in PyPI top 5000 projects. For this, they use and scripts by Victor Stinner.

    $ python --help
    usage: [-h] DIRECTORY [COUNT]
    Download the source code of PyPI top projects.
    positional arguments:
      DIRECTORY   Destination directory
      COUNT       Only download the top COUNT projects
      -h, --help  show this help message and exit
