withfire.app

AI-powered resume tailoring tool that productizes an automated job-application pipeline. It includes a bookmarklet intake system that parses job postings and adds them to a list, an improve-over-time tailoring loop that identifies skills mentioned in postings but missing from the user's profile and asks about them to refine the profile, and output options that produce polished, human-looking tailored resumes. The author reports it increased their job hear-back rate roughly 5x.

ministar

Astrophotography tool that automates the hard parts of untracked astrophotography. It uses plate solving to help point the camera at a target and live-stacks the resulting images while accounting for Earth's rotation. It is early-stage and the author plans to port it to Linux/Raspberry Pi so a minimal astronomy rig can be built from just a DSLR, a 3-way head, a tripod, a power bank, and a single-board computer.

Epoptes

Open-source tool for running coding agents (Claude, Codex, Pi, Antigravity) autonomously for long periods while the user can monitor and steer their work. It has been used for game development, research, and building other tools, with some runs lasting over 20 hours.

counterparts.ai

A free, open-source, fully local memory system for Claude modeled after human memory. It lets older memories fade so nothing gets stale, 'dreams' to merge similar memories, updates memories when facts change, and has prospective memory that can remind you of things in the future. Because it acts as Claude's own memory, it develops a self-identity and gets to know the user over time, strengthening or fading habits automatically (e.g., a ping-pong shortcut). It complements the built-in memory file rather than replacing it, requires no API keys, and avoids stale files and hundreds of markdown docs.

DocuView

DocuView is a real estate software product built as an opinionated alternative to other players in the space. It focuses on the features the builders themselves want, rather than a generalized product where users only use a fraction of the functionality.

HeliosCAD

A code-based CAD application built on the Aetheris geometry kernel, designed for LLMs first and foremost. It is adding visual programming to the UI and a new drafting mode called IntelliDraft that works closer to how mechanical engineers actually sketch.

Concept

A programming language positioned as a successor to C++, based on the idea of C++20 concepts, featuring templates, comptime, Einstein tensors, async/await, explicit state machines, CPU inference, Vulkan support, easy C interop, and safety proofs built into the language itself. It currently compiles to C11, self-hosting is in progress, and it targets AMD64.

benchix

A learning-project x86-64 kernel implementing a subset of the Linux syscall ABI, written in Rust. Current work adds tracing support, followed by allocators, including fallible allocation like the Linux kernel and questions around overcommitting and OOM handling. Built without LLMs to deeply understand OS kernels.

Newspeak PostgreSQL TCP protocol implementation

A Newspeak implementation of the PostgreSQL TCP wire protocol that enables talking to a GnuCash database from the Chrome web browser, built on the author's Newspeak TCP library. The implementation is described as bare minimum and probably very broken, but can already parse a Postgres result set from a simple query; a one-minute demo video shows result data printed to the console from a Newspeak workspace.
