hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

THE PROBLEM

🌲 Invert a binary tree! 🌲

Except with 3 catches:

It must invert the keys ("bit-reversal permutation")
It must be a dependency-free, pure recursive function
It must have type Bit -> Tree -> Tree (i.e., a direct recursion with max 1 bit state)

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

Agile Contract Guide

This document is a guide to writing agile contracts. Unlike traditional contracts, an agile contract does not specify individual tasks to be completed by the Contractor. Rather, an agile contract specifies how the Client and Contractor interact, and how the Contractor is paid. The Deliverable Work performed for the contract is determined through an ongoing collaboration between the Client and the Contractor.

Agile contracts require a great deal of trust from both the Client and the Contractor. This trust is fostered through tight feedback cycles and well-defined responsibilities that both parties can expect from each other. More so than traditional contracts, an agile contract requires active participation from the Client.
