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 support@company.com), 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.

Boot Sector Games

A list of playable boot sector games, most of which are on github. Fun to play, great to learn from. There are also many cool non-booting boot sectors out there that aren't games (so more like demos), but this page is just reserved to interactive boot sectors / games. This list is also not complete, but not on purpose, it is a best effort collection of games, so if you know of any fun boot sector games, please contribute.

This page lists a collection of 31 games spanning several authors: nanochess, me, daniel-e, shikhin, JulianSlzr, XanClic, QiZD90, darkvoxels, guyhill, w-shackleton, egtzori, VileR, ish_works, franeklubi, queso_fuego, franeklubi, Jethro82, waternine9, tevoran, palma3k, taylor-hartman. peterferrie should also be mentioned as he has touched a lot of these games.

TetrOS

Tetris Clone. Full color, no score. This was one of the older boot sector games out there. ![tetros](https://gist.github.com/assets/1570856/3a0d1023-cbe6-4b4d-
