We ship node_modules by hand. So I built this.

I work on a React Native app that's old enough to remember when class components were the default. Some packages in node_modules/ have been edited by hand — not patched, not forked, literally opened in a text editor and saved. The "fixes" have been there for years. Nobody kept track of which files. And whenever we onboard a new dev, we hand them a 250 MB .rar of the entire node_modules/ folder, because running yarn install would wipe everything out.

Our setup runs like an old lady. Not in a mean way — it works, it gets to the store and back, it just shouldn't be doing what it's doing in 2026. We have a postinstall hook that mostly works on prayer. We have a Confluence page from 2021 that lists "which packages are safe to reinstall." Half the packages on that list no longer exist.

Somewhere in the last few years, 12+ packages accumulated hand-edits. Some are one-liners. Some are entire sections of code commented out or rewritten. The senior dev who

Cherry-Pick Check Report

I ran into a situation where I needed to verify whether a feature branch (J27910_fix) had already been included in a release branch (2616).

At first glance, the history looked messy — multiple merges, unrelated commits, and overlapping changes from other tickets. This made it unclear whether my work (tagged with J27910) had already been merged or if I needed to cherry-pick it manually.

Instead of guessing or risking duplicate changes, I decided to validate it properly using Git.

Recently, my manager assigned me a rather unusual task --- to manually collect every commit ID related to a Jira card.
While Git already provides tools to automate this, I still had to gather all commit hashes one by one.

📝 What Happened

I was working on feature updates when suddenly my manager pinged me: > "Please list down all commit IDs for Jira card J2667."

🧠 Context

While maintaining a long-lived production repository, I noticed an unusually large .git/objects/pack file consuming hundreds of MBs.
This was affecting cloning speed, CI performance, and overall repository health.

Install Python 3.12 on Ubuntu 20.04 (WSL) using pyenv

This guide provides a clean and safe method to install Python 3.12 on Ubuntu 20.04 running under WSL2, without touching the system Python.

Linux distros normally have a Python version tied to the distro and used for various admin scripts. You should not expect to follow the latest releases of Python. And don't try to force change it because you could break your OS. If you need newer Python versions for your work, install it in user space.

Linux 20.04 come with python 3.8 which not supported natively to latest version of python (ex. 3.12.x), so by using pyenv will help you install other version of python without touching OS system, and it won't break your system.

Detecting Changes in `node_modules` for Patch Package

When you edit files inside node_modules, Git does not track them --- so git status won't help detect changes.
This guide explains how to use sha1sum (or md5sum) to detect modified packages.

Rust Installation via Alternative Method

If you follow the official website, they recommend using the command:

$ curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh

But I encountered an OpenSSL connection peer reset error.
Since that failed, I tried another way, which succeeded.

🐞 Git Incident Report: Local `main` Branch Got 19 Unexpected Commits

📅 What Happened

One morning, I had already finished developing a feature on a separate branch. Before creating a Pull Request (PR), I merged main into my feature branch to make sure everything was up to date.

After that, I switched to the main branch and ran:
