This is a non-exhaustive list of projects I developed.

Pocket Statistics

Pocket Statistics is a website that will retrieve and analyze your Pocket data. You can find it here.

It is deployed using an NGINX server (as a reverse proxy) and Waitress running on Arch Linux over IPv4 and IPv6.

Certbot (from Let’s Encrypt) is used to provide (and regularly renew through a systemd timer) TLS certificates.

nftables is used to build an allowlist-based firewall and to prevent SSH brute-forcing and ICMP flooding.

Dungeon

Dungeon is a text-based open-world Java role-playing game.

In 2017, Dungeon won a $1024 software quality award.

Walls of Doom

A platformer in C, rewritten in modern C++.

Better Chest Organizer

Better Chest Organizer is a mod for Stardew Valley written in C#. The default in-game chest organization functionality is very incomplete, often not using enough criteria when determining the chest item order. To make matters worse, the default implementation does not use a stable sorting algorithm. This mod provides better automatic chest organization, fixing these problems.

Examples

Example 1

A chest with artisan products after sorting by the in-game button

A chest with artisan products after sorting by the in-game button. The jellies (red jars) are mixed with the other product types.

Example 2

A chest with mushrooms of varying quality after sorting by the in-game button

A chest with mushrooms of varying quality after sorting by the in-game button. The mushrooms are sorted by their variety, but their quality has not been taken into account.

A chest with mushrooms of varying quality after sorting by the mod

A chest with mushrooms of varying quality after sorting by the mod. The mushrooms are sorted by their variety and then by their quality.

Self-organizing tree models for image synthesis

This is a C++ implementation of the main ideas from Wojciech Palubicki, Kipp Horel, Steven Longay, Adam Runions, Brendan Lane, Radomír Měch, and Przemyslaw Prusinkiewicz. 2009. Self-organizing tree models for image synthesis. In ACM SIGGRAPH 2009 papers (SIGGRAPH ‘09), Hugues Hoppe (Ed.). ACM, New York, NY, USA, Article 58.

The code is fairly well-documented in order to help an interested reader better understand how the paper was implemented.

See the GitHub repository.

BigWord

An application to efficiently find words in a dictionary from a multiset of letters. This is, the application finds the largest possible words from a bag of available characters.

Examples

$ ./bigword linkedlists
> instilled
> kindliest
> niellists
> slinkiest

$ ./bigword abcdefghij
> bighead
> jibhead

$ ./bigword aeioubsdlinux
> unoxidisable

Design

Data is serialized after processing in order to speed up subsequent runs.

Performance

On average, the application can query against a dictionary of 500,000 words in around 50 milliseconds.

See the GitHub repository.

Contagium

A JavaScript game.

See the GitHub repository, the website.

Photo

A Java image manipulation library.

See the GitHub repository, the project page.

Notes

My public LaTeX notebook.

See the GitHub repository, the last release, the issue tracker.
