1 BUG, $50,000+ IN BOUNTIES, HOW ZENDESK INTENTIONALLY LEFT A BACKDOOR IN HUNDREDS OF FORTUNE 500 COMPANIES

A 15-year-old bug hunter discovered a vulnerability in Zendesk's email collaboration feature that allowed attackers to access customer support tickets from any company using the service. This exploit was initially dismissed by Zendesk's bug bounty program as "out of scope," but subsequent public disclosure of the vulnerability forced Zendesk to take action. The bug hunter then discovered a second, more serious exploit that could allow attackers to gain access to private Slack workspaces using Zendesk, which was fixed later.

NODE.JS, PIPES, AND DISAPPEARING BYTES

Piping large amounts of JSON data from a Node.js command to another command results in truncated output. The issue stems from the asynchronous nature of Node.js's `process.stdout.write` when writing to a pipe on POSIX systems. When the pipe buffer is full, `process.stdout.write` returns false, and further writes are blocked until the pipe is read. The solution involves subscribing to the `drain` event of the `process.stdout` stream to resume writing after the pipe has been filled.

THE INTERACTIVE GUIDE TO RENDERING IN REACT

React re-renders a component only when its state changes, triggered by an event handler that modifies the state using useState's updater function. It handles multiple updates within an event handler by batching them, applying only the result of the last invocation. StrictMode is a development mode that forces components to re-render twice to ensure purity and resilience.
