ssa

A shell-based AI CLI tool that runs small local models (around 2B parameters) to help debug Linux issues when offline, with the ability to switch to cloud-based models for harder tasks once back online, all while feeling like a CLI tool.

TPU v5 tensor core reverse engineering

This project reverse engineers the tensor core on Google's TPU v5 and documents its instruction set. The work stems from the belief that Nvidia GPUs' architecture is a bit subpar for machine learning and that TPUs could be a viable alternative but remain rather undocumented.

Flopper

A site building a holistic view of the GPU market, aggregating providers, rental prices, vendor information and GPU specs. It includes tools such as an LLM GPU calculator that estimates how many GPUs are needed to run a given model based on power/flops, precision, context length, concurrency and other requirements.

Haptrix

A Core Haptics editor for iOS. With the release of the iPhone Duo, the editor finally makes sense to use on-device, and a new UI has been in development.

Wayfinder

A Rust-based tool that optimizes LLM agent memory on complex projects by adding a semantic layer on top of an LLM Wiki. It improves agent knowledge over a codebase, cut token usage by 30% in the author's benchmarks, and includes features for handling concurrent agents updating shared memory to keep information reliable and fresh. Published to PyPI (installable via "uv tool install wayfinder-memory") and compatible with almost all agent harnesses.

Hack

iOS Hacker News client app that has been around for 9 years. This update adds support for iPhone Duo, whose vertical stack menu on the right side is incompatible with the app's original custom-view menu bars and navigation buttons, by switching to iOS native navigation bars and menu bars along with other improvements; it is in final testing ahead of submission to Apple.

Incredible

A Rust Text User Interface (TUI) framework that is modular, declarative, event-driven, and reactive. It builds cross-platform apps from one unified code base, compilable for the terminal (macOS, Windows, Linux), a standalone native window (macOS & Windows 11), or the browser via WASM.

Neural quantum states via weight-space programming

A research project applying recent MIT weight-space programming techniques to neural quantum states — neural networks that represent a quantum wavefunction. Novel networks were produced for a few hundred dollars of cloud GPU, versus an estimated tens of thousands of dollars with traditional training.

SkyMap

A browser-based open source universe explorer that gathers, parses, and visualizes publicly available scientific data in real-time. It includes galaxy survey visualizations, hi-res tiled Earth and Mars imagery, a Gaia star field with 16 million stars, a Milky Way renderer, and more.

Archme

A code abstraction tool that scans a codebase and turns it into permanent C4 and sequence diagrams, keeping them up to date on each commit. Instead of reviewing a 10k-line coding PR, users review a ~30-line change to the diagrams. Runs locally via an npm CLI (@archme/cli) so code never leaves the machine.

asm.build

A package manager for assembly projects, built on the thesis that as AI makes writing code cheap, software can be written directly for each architecture in assembly rather than higher-level languages like Rust, since running costs will matter more.

Peregrine

An integrated terminal and file browser with enhanced autocomplete and search, built to replace native OS terminals and file browsers. Also includes tailored OS utility features such as an advanced clipboard and a scratchpad.

Unmute Party

This is a browser-based platform of multiplayer party games for remote teams, played together during a Zoom or Teams call. Servers are EU-only for now with US servers planned for the next week; most features are free, while the paid tiers aren't working yet and can be unlocked with a promo code.

Travel agency (boa.ba / dobosnia.com)

A travel agency the author runs, made viable with the help of agents that manage ads, social media, and website content. The first site, boa.ba, went quite well, and a new site at dobosnia.com is being prepared.

HostsTray

This tray utility manages the hosts file and includes a built-in reverse HTTPS proxy that installs a self-signed CA and generates certificates on-the-fly. It forces the browser to flush its DNS cache by killing background keep-alive connections, and exposes a simple API (which also serves the agent skill) so local coding agents can control it.

Kavla

Open source SQL canvas that adds interactivity to queries: typing {var} in a SQL statement pops out a knob control that infers the column's type and values, e.g. a slider for a score threshold. Includes a browser-based demo running entirely in WASM with no login.

Tech explainer YouTube videos

A YouTube video project creating explainer videos on technical topics, such as speculative decoding and how it speeds up AI inference. Topics are chosen and scripts are written by hand, while AI handles most of the video editing.
