clview
A CLI command that displays PDFs, images, Word documents, spreadsheets, drawings, Markdown and HTML directly inside the terminal (kitty, ghostty, etc.), and works well with tmux and over SSH.
Swirl Together
An art therapy sandbox built on Pavel Dobryakov's fluid simulation. It is nearly finished, planned for release on Steam and later as fully open source on GitHub, with a free playable browser version available at the project's site. The author has used it personally over the years and finds it soothing.
fluximp
This AI coding agent optimizes token usage through context management: breaking the prefix to remove old items from the context and doing rolling summarization to keep prompt size down, aiming to beat standard context management approaches on total cost. On the same benchmark it reduces the number of requests by a factor of about 3 relative to oh-my-pi.
CyberStory
An interactive fiction platform that blends AI storytelling with generated images, video, and text-to-speech, offering user choices at the end of each story page. It features AI-driven historical fiction adventures across time periods, alternate histories, romance, and more, and users can also build out their own stories.
Quillium
This is a nonlinear writing editor that tracks all versions of different words, paragraphs, sentences, and drafts, so writers no longer juggle files like Final_FINAL_v3_essay.docx. The author polished it up to dogfood it for their college applications.
Native Postman alternative for iOS and Mac
A lightweight native API testing app for iOS and Mac built as an alternative to Postman. It reaches Postman feature parity at around 4MB, adds iCloud sync, and supports MCP so test suites can be controlled from Claude on Mac. It includes no-code style assertions and is being made available to others via TestFlight.
Research and doc work harness
A work harness the author is setting up to make research, experiments, and documentation work more efficient at their job.
AI generation tool exploration for game engine development
A home project evaluating AI generation tools beyond ChatGPT and Claude — including music, sound effects, video generation, and motion generation — with the goal of working with a game engine.
FreeBSD 15.2
FreeBSD 15.2, a FreeBSD operating system release scheduled for early December, handled by release engineering. The biggest change from the release engineering perspective is using got instead of git, dramatically reducing the dependency tree.
Aetheris
An almost purely analytical 3D geometry kernel/engine focused on performance and reliability, with aggressive optimization that makes building 3D models faster, trading away unusual modeling features like asymmetrical or variable-radius fillets. It can be used directly by agents instead of going through a UX layer.
Sudoku for reMarkable Paper Pro
A sudoku game built for the reMarkable Paper Pro e-ink tablet, offering a cleaner playing experience than paper boards or phone sudoku apps.
Camera Nocta
A film-style black and white photography app for Android and iPhone (iOS pending App Store approval, currently in TestFlight). It features a custom RAW pipeline with the author's own denoise that preserves natural grain instead of the 'skin waxing' effect of typical noise reduction and AI, an opinionated UI geared toward shooting over editing, and custom color-pushing editing tools modeled on dye and pigment rather than saturation sliders. Tuned for portraits and fashion photography.
Twitch-streamed Linux coding competition
This project stages live competitive coding matches: two contestants are placed in a well-equipped Linux environment (checkpointed fly.io Sprites), given the same task, and race to complete it first, with the whole match streamed to Twitch. Contestants can bring their own dotfiles, workflows, harnesses, and editor configs, letting viewers watch how the work gets done. Planned 'weight classes' will fix the level of harness capability per tier — from no agents at all, to small local open-weight LLMs, to large open-weight models, to frontier models — and users will be ranked in each class so people can compete to deliver the most at various cost tiers.
RCHIVE
This desktop app for Windows, Mac and Linux catalogs, searches and reorganizes files across computers, NAS devices and drives. It scans many sources, provides unified deep search across the entire catalog including drives that are online or offline, lets users virtually organize and clean up large archives, and resiliently copies or moves files when restructuring on disk, with quick browsing via previews and metadata. It works offline, collects zero telemetry, deletes nothing, is fully deterministic in operation, and can run as a portable version from a USB drive.
RCHIVE Examiner
This free companion app is an ncdu-like disk usage analyzer that shows where hard drive space went and what is hogging it. It is currently available in the macOS App Store, with Windows and Linux versions releasing soon.
RCHIVE standalone CLI components
This planned set of free standalone packages exposes the discrete, decoupled components underlying RCHIVE and RCHIVE Examiner for people who might find them useful, especially in CLI scenarios.
clingon
An interactive terminal workflow tool that functions as a command cheat sheet with its own built-in shell and composable workflow recipes, all backed by markdown. Commands and recipes stay human-readable while remaining executable by anyone or anything, and Warnings or Cautions in the markdown surface as warnings and cautions when running commands in the shell.
Networks by Analogy
Dynamic landing page for the book 'Networks by Analogy' (networksbyanalogy.com), updated so users can explore the book in a visual way.
Goose-based Matrix chatbot
An internal Matrix chatbot built on Goose that acts as a custom agent to automate tedious tasks in the author's one-person company.
Samosa Math
This tool audits mathematical derivations step by step, checking for mistakes in derivations written by a person or produced with AI assistance.
UltiMidi
A music game platform the author is almost ready to release at ultimidi.com. It is not a rhythm game yet, but the goal is to add more mini-games including rhythm games, and more instruments: it currently has piano, with guitar and ukulele planned and drums uncertain. It grows out of the author's earlier university project that used a basic neural network to detect exactly which guitar string and fret was played, and an earlier small game playable with a real guitar.
Traditional roguelike
A traditional roguelike game, built as a fun challenge, with hand-made sprites created by the developer.
Rindraw
A digital drawing app positioned as a (hopefully better) Procreate alternative, running on Mac, iPad, and iPhone, built to let anyone express their creative ideas.
Knotend
A grid-based flowchart editor that replaces a free-form canvas with a grid where all nodes are the same size and sit in a cell. It adds spreadsheet-like keyboard navigation and autolayout to make editing flowcharts much faster and keyboard-centric.
EV software
EV software, which the author notes is their main current focus among several projects.
Performance book
A book on performance that the author is writing.
Edu/political project
An unnamed project related to education and politics.
Voting systems upgrade design
A design for an upgrade to voting systems.
SSH BBS game
A BBS-style game accessible over SSH.
