  • name-needed

    🎮 A one man effort to produce an open source, intuitive and high performance Dwarf Fortress-esque game. Needs a name.

    I've been alternating between two long term Rust projects, which seems to work in keeping the motivation up for both!

    A Dwarf Fortress-like game (and engine):

    A x64 operating system:

  • userbase

    Create secure and private web apps using only static JavaScript, HTML, and CSS.

    I filled my own need with

    I have a minor, but chronic medical condition I am trying to get in check, and I just wanted something incredibly simple to identify good and bad days. I was inspired by "year in pixels" calendars.

    And I took the opportunity to try out Userbase[0] and build something with a secure backend and no tracking, considering the potentially sensitive nature of it.

    No plans for monetization at the moment. I could see adding more features such as tracking multiple data points, stats, correlations, notes, etc., and creating a premium version. I would need more users and feedback.


  • OPS

    OPS - Build and Run Open Source Unikernels. Quickly and easily build and deploy open source unikernels in tens of seconds. Deploy in any language to any cloud.

  • dotfile

    Simple version control made for tracking single files


    I've always found various solutions that use git for sharing configuration files cumbersome. I set out to make my own simple version control system, and a lightweight web application where I can browse and edit them remotely. The main idea is that paths are aliased to simple names, so I can say `dotfile pull i3` and it will install to ~/.config/i3/config

    Overall the project is stable and I use it daily for all sorts of miscellaneous files.

  • deltaflow

    A GPU-accelerated differentiable fluid simulator written in JAX.

    A couple on and off, but most recently a GPU-accelerated differentiable fluid simulator:

  • coprocessor.js

    serial-based, nodejs-backed, remote code execution system

    I'm working on a system hand off nodejs workloads over a serial port to another machine running some host software.

    My intent is to easily write Internet-connected software for old machines where a host machine is doing all of the heavy lifting. I have been messing with 68k Macintosh systems first. The code is very much a work in progress that I am actively chipping away at, and not in a usable state just yet. I write a lot of nodejs professionally but haven't used C since college so its been a fun project.

    nodejs software for the "modern" machine:

    C software (targeted at a 68k mac) for the "slow" machine:

  • dev-portal-frontend

    A StackOverflow / Reddit / Disqus / Talkyard clone

  • kanception

    Open source recursive Kanban board

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

  • cloud-from-scratch

    Build yourself a private self-hosted full-stack personal cloud system.

    This CloudFromScratch, right?

    I have a document for myself where I note down what I believe to be future industries — trying to time the market. In the same way you might've timed the market in the early part of the previous decade by betting on remote working becoming a pretty viable option (hindsight is 20/20 tho!)

    Self-hosted for privacy reasons, to me, is like a bomb waiting to explode. Just like covid accelerated our habits around healthcare (Perhaps future generations will look down on those who don't wear a mask when one catches a cold, the same way we look down on those who don't wash their hands after using the toilet... but in the 17th century that wasn't a thing), I believe mass privacy-awareness will come with a major leak/event.

    Looking forward to Apr 1st (if the beta is launched there and it won't be just April Fools' lol!

    P.S: Feedback for feedback, if you're down?

  • archivy

    Archivy is a self-hosted knowledge repository that allows you to safely preserve useful content that contributes to your own personal, searchable and extendable wiki.

    I'm working on Archivy [0] - a knowledge management system built around extensibility.


  • SearchStory

    Lucene based search application to search your own history (notes, papers, browser history)

    I came across that app a little while ago - it definitely inspired my current side project! which is a similar locally-hosted web app with a Lucene search index

  • Clendar

    Clendar - universal calendar app. Written in SwiftUI. Available on App Store. MIT License.

    I have been working on a universal Calendar app for Apple platforms, as iOS, iPadOS, watchOS and macOS specifically; named Clendar. [0][1]

    My goal is to learn SwiftUI and explore new Apple technologies.

    The app is now open source on GitHub as well, it's my way to give back to the community as I was learning it. [3]

    Feedback welcome!

  • sogdb

    An open database for stadia games

    I've been busy with a couple of projects

    With a friend I build ( ) - A link "shortener" where the url redirects to diffrent targets based on device or OS.

    On my own I build SOGDb ( ) - An open database for all available Stadia games with filtering options for local/online multiplayer support and such.

  • server

    Scinna is a self-hosted screenshot sharing site (by scinna)

    I'm building Scinna (

    It aims at being a fully featured server app to share screenshots, and will be having a desktop and android client. The far-far end goal is to have something as good as ShareX but self-hosted and cross platform. The client will feature a toolbox as the one found in ShareX which I really love but with the added benefit of allowing plugins to enrich it

  • tubesync

    Syncs YouTube channels and playlists to a locally hosted media server

    I've been working on and off on TubeSync, a PVR for YouTube:

  • bayes-bet

    Productionized NHL hockey model predictions with Django fontend

    I wrote a bit about it in a blog post over the summer:

    There are other posts on my blog about this project. There are links directly to them in the GitHub README:

  • qrxfil

    Exfiltrate files via QR codes

    qrxfil: file exfiltration across airgaps using QR codes.

    Splits files across multiple QR codes for “sending” across air-gapped computer systems. Generates numbered PNG files to scan.

    The codes contain metadata about chunk number (e.g. “007 of 078”) to enable out-of-order scanning.

    It's a fun way to learn Rust, and a great trick to get terrified looks from security folks.
