I wrote a package for other Ziguanas to use in their Zig projects. 
It's a small package for generating all possible permutations of a list using Heap's algorithm. My goals were to avoid allocating memory on the heap and using an Iterator pattern, resulting in the next permutation not being generated before it's needed.

It was a success and a great learning experience :)

I participated in this year's CSAW qualifying CTF. I didn't do much, but I succeeded at some binary exploitation, reversing some python, utilizing hashcat to crack some hashes and doing an easy web challenge. I also managed one of the harder web challenges - albeit after the competition ended. 
I greatly enjoy the CTF format that to me is like a bunch of bite-sized puzzles, forcing me to think about things I rarely get to think about 🤯

I wrote a program that plays Minesweeper. Initially I tried screenshotting the game and to image recognizion, but ended up using the Win32 API to open the game process and read the memory containing the board layout.

I made a website, hurtig.ninja, a filesharing site that's simple and anonymous to use. I often wanted to share files (and still do) and needed a better solution than any existing one.

It's made with Typescript, .Net Core, running on an Ubuntu server with MongoDB to store references to files.
