Existing simulators are dated, and every paper sketch has to be redrawn by hand before it can be tested.

A cross-platform desktop simulator on Avalonia with dependency injection, MVVM and a JSON serialisation layer that survives clipboard cut/copy/paste of whole circuits. Alongside it, SketchLogic: a fine-tuned YOLO detector plus OpenCV contour analysis that reads gates and wires off a photograph and reconstructs the topology. Components follow IEEE/ANSI 91-1984 shapes, and simulation frequency is adjustable per clock.

Simulates a mini-CPU. Ships self-contained for Windows, Linux and macOS with CI, xunit coverage and no runtime install required.

A million research papers with no fast way to rank them by relevance, and no machine big enough to hold the metadata in memory.

A segmented index (lexicon, postings, docids and a forward index per segment) with BM25 scoring across all of them. Metadata is lazy-loaded by byte offset, so startup costs about 16 bytes per document instead of the whole CSV. Three LRU caches sit in front of search, AI overviews and document summaries. Twelve REST endpoints, JWT-protected admin routes for uploading new corpus slices.

Sub-50ms queries across the full corpus. New document sets index in place without a rebuild.

Getting a real codebase into a model's context means opening files one at a time and pasting them in order.

One command that walks the tree, respects .gitignore, filters to code extensions, and lets you pick files interactively, then copies structure and contents to the clipboard, zips them, or exports to tree, JSON or Markdown. It can also move your shell into the resolved root, so listing and navigating become a single step.

Installable with pip install gitree. Deliberately small and readable, with outside contributors and merged pull requests.
