-# Development
-
-> All changes MUST follow the vendor/tiara-gitflow-spec.git and no work MUST be
-> started without a TODO issue.
-
-## Prerequisites
-
-- Python 3.9+
-- [Pipenv](https://pipenv.pypa.io/)
-- [tox](https://tox.wiki/) (installed via Pipenv dev dependencies)
-- Node.js (for the `@byteb4rb1e/mime-todo` issue tracker CLI)
-
-## Setup
-
-Iniitialize Git submodules:
-
-```bash
-git submodule update --init --remote --recursive
-```
-
-Install dependencies (includes the package in editable mode):
-
-```bash
-pipenv install --dev
-```
-
-
-## Tooling
-
-### Package
-
-The project is packaged as `byteb4rb1e.utils` under a namespace package
-layout (`src/byteb4rb1e/utils/`). It is installed in editable mode via
-Pipenv.
-
-Build a distribution:
-
-```bash
-pipenv run dist
-```
-
-### Testing
-
-Tests are managed by tox. Test environments are defined in `tox.ini`:
-
-```bash
-# run all test suites
-tox
-
-# run specific environments
-tox -e unit-py313
-tox -e lint
-tox -e format
-```
-
-| Environment | Purpose |
-|---|---|
-| `unit-py3{9-13}` | Unit tests |
-| `smoke-py3{9-13}` | Smoke tests |
-| `integration-py3{9-13}` | Integration tests |
-| `lint` | Type checking (mypy) |
-| `format` | Code style (autopep8) |
-| `audit` | Dependency audit (pip-audit) |
-
-### Issue tracker
-
-Issues are tracked in the `TODO` file using the
-[MIME TODO](https://specs.code.tiararodney.com/mime-todo/) format. Use the
-`@byteb4rb1e/mime-todo` CLI to interact with it:
-
-```bash
-# list issues
-npx @byteb4rb1e/mime-todo list
-
-# show a specific issue
-npx @byteb4rb1e/mime-todo show 3
-
-# create an issue
-npx @byteb4rb1e/mime-todo create --type feature --title "Title" --plan "Description" --module homeostat
-```
-
-See [CONTRIBUTING.md](CONTRIBUTING.md) for the full issue lifecycle.
-
-### Publishing
-
-Build wheel and source distributions:
-
-```sh
-pipenv run sdist
-```
-
-Configure publishing options:
-
-`~/.pypirc`
-```
-[distutils]
-index-servers =
-    tiararodney
-
-[tiararodney]
-repository: https://pypi.code.tiararodney.com/root/byteb4rb1e/
-username: <username>
-password: <password>
-```
-
-Publish to pypi.code.tiararodney.com:
-
-```sh
-pipenv run sdist:publish:tiarardoney
-```
-

-Title: implement Rabin-Karp rolling hash algorithm
-Status: done
-Priority: high
-Created: 2025-05-05
-Description: After testing a couple of string search algorithms, I've ditched
-             the idea of using KMP as my use-case gives no advantage compared to
-             naive searching. In addition I've came upon the challenge that many
-             string search algorithms are optimized for search on a linear
-             buffer, which in my case is not applicable as the implementation
-             the search algorithm is for uses a circular buffer. Rabin-Karp
-             seemed promising. I've come up with a different approach though,
-             which is still based on rolling hashes, therefore, as a base, I
-             need an implementation of the original Rabin-Karp rolling hash
-             algorithm
