Howdy, welcome to my GitHub profile! The sections below outline the projects that I update the most often, am the most proud of, or want to showcase for some other reason.

Thanks for visiting! 👋

Link: https://github.com/AustinTSchaffer/Notebook

This repository contains notes that I've taken on various technology-related topics. I use Obsidian as a note taking tool, which uses a semi-standard flavor of Markdown, and allows you to correlate notes based on tagging and direct page-to-page links. This notebook is slowly being filled with all of the notes and resources that pertain to my journey through Georgia Tech's Online Masters of Computer Science (OMSCS) program.

This repository contains various small scripts, mostly related to various programming puzzles and challenges. The repository gets its name from reddit.com/r/dailyprogrammer, which is a subreddit dedicated to programming challenges falling under 3 different difficulty tiers, "Easy", "Intermediate", and "Difficuly". This repository is unfortunately now mostly defunct apart from its posting history, but since I've expanded the scope of this repository to cover a variety of other challenge sites, including

• Advent of Code
• LeetCode
• CodeWars
• Various self-imposed challenges, using and abusing Python
• The "learn this language" sections of various programming languages

Really proud of this one. The .gif is super satisfying in my opinion. Check out the link if you want more details.

Link: https://github.com/AustinTSchaffer/SudokuSolver

In a similar vein to the previous project, I wrote a Sudoku solver based in equal parts on strategies that I have developed playing the game by myself, and on knowledge that I found on an online resource containing advanced Sudoku strategies. I didn't want to just end there, so I made sure that the solver worked on any game that follwed the same basic rules:

• Rule 1: The game has some maximum number of types symbols that can be placed into the game.
• Rule 2: Each cell can only contain one symbol.
• Rule 3: Each cell is part of some number of cell groups. No cell groups can have any duplicates among their member cells.

Games that can be described by these constraints are referred to as logic-based, combinatorial, symbol-placement puzzles. There are a surprising number of puzzles in this category of games.

This repository contains a pip install-able git subcommand, git ranch, which allows end users to more easily order a 1-gallon jug of Kraft Ranch Salad Dressing from Amazon.

I created this after mistyping git branch for the 1,000-th time.

Link: https://github.com/AustinTSchaffer/This-Repo-is-a-Blockchain

This repository is a fairly simple Proof-of-Work (PoW) git repository. This is implemented using a post-commit hook which probibilistically rejects about 99.98% of all commits, by only accepting commits whose hashes start with at least at least 3 zeroes.

There are multiple currencies based on this concept.
