codemaxxed
CLI tool purpose-built to generate the maximum possible lines of code
codemaxxed is a deliberately experimental and satirical project that generates massive amounts of code automatically to explore and critique the idea of measuring productivity through lines of code. The repository continuously grows through automated workflows that generate new files and commits at regular intervals, resulting in extremely large codebases with minimal functional value. It is built using the companion tool “codemaxxing,” which allows users to control parameters such as the number of lines generated, the level of randomness, and the speed of generation. The project intentionally produces nonsensical or low-quality code, including exaggerated naming patterns and redundant structures, to highlight the absurdity of equating quantity with quality in software engineering. It serves more as a conceptual or artistic experiment than a practical tool, illustrating how metrics can be gamed in modern development environments. -

pdfsandwich generates "sandwich" OCR pdf files, i.e. pdf files which contain only images (but no editable text) will be processed by optical character recognition (OCR) and the text will be added to each page invisibly "behind" the images. pdfsandwich is a command line tool which is supposed to be useful to OCR scanned books or journals. It is able to recognize the page layout even for multicolumn text. Essentially, pdfsandwich is a wrapper script which calls the following binaries: convert, unpaper, tesseract, gs, and hocr2pdf (if tesseract < 3.03). It is known to run on Unix systems and has been tested on Linux and MacOS X. It supports parallel processing on multiprocessor systems. In contrast to most competing sandwich programs, it performs preprocessing of the scanned images, such as de-skewing or removal of dark edges etc. For further information please read the manual: http://www.tobias-elze.de/pdfsandwich/index.html

Scoop Installer
A command-line installer for Windows
Scoop is a command-line installer for Windows. If you have built software that you would like others to use, Scoop is an alternative to building an installer (like MSI or InnoSetup). You just need to compress your app to a .zip file and provide a JSON manifest that describes how to install it. Scoop downloads and manages packages in a portable way, keeping them neatly isolated in ~\scoop. It won't install files outside its home, and you can place a Scoop installation wherever you like. For terminal applications, Scoop creates shims, a kind of command-line shortcut, inside the ~\scoop\shims folder, which is accessible in the PATH. For graphical applications, Scoop creates program shortcuts in a dedicated Start menu folder, called 'Scoop Apps'. This way, packages are always cleanly uninstalled and you can be sure what tools are currently in your PATH and in your Start menu. -

GeoIP
This project automatically generates GeoIP files in multiple formats
GeoIP is a community-maintained project that generates and publishes enhanced GeoIP/Geo-database and IP-location/routing data in multiple formats (e.g. V2Ray .dat, MaxMind .mmdb, and others) to support proxy, VPN, or routing tools requiring IP-to-country/region resolution. Rather than depending solely on the official GeoLite2 data, geoip augments and merges data sources (especially for certain regions) to improve coverage or tailor by use-case (e.g. proxy-specific rules, private networks, or region-based classification). The repo provides automated, periodic releases (e.g. weekly or on schedule) and also offers a CLI tool so users can regenerate or customize geo data in the format they need — for example, producing a .dat file for V2Ray / Xray-core, or a MaxMind-compatible .mmdb. -

GitHub CLI
GitHub’s official command line tool
GitHub CLI is a free and open-source tool that brings GitHub functionality directly to the command line. It allows developers to manage repositories, pull requests, issues, and releases without leaving the terminal. With simple commands, users can perform common GitHub tasks such as checking out pull requests or creating issues locally. The CLI helps eliminate context switching by enabling a full GitHub workflow from the terminal environment. Developers can also interact with the GitHub API to automate tasks and create custom scripts or command aliases. Additionally, GitHub CLI supports connections to both GitHub.com and GitHub Enterprise Server for enterprise-ready workflows. -

Obsidian Skills
Agent skills for Obsidian
Obsidian-Skills is a repository of agent skills tailored for use with Obsidian and any Claude-compatible agent that follows the standard Agent Skills specification, enabling AI assistants to better understand and interact with Obsidian content. These skills are markdown-driven specifications that teach Claude Code (or similar agents) how to perform context-aware tasks within Obsidian’s unique environment, such as interpreting different file types and workflows, automating workflows tied to notes, or enhancing agent responses with structured knowledge. By providing formal descriptions of patterns, conventions, and workflows common to Obsidian users, the skills empower AI tools to give more relevant suggestions, generate content that adheres to user conventions, or execute complex multi-step operations that respect the knowledge graph and file relationships. -

dirsearch
Web path scanner
An advanced command-line tool designed to brute force directories and files in webservers, AKA web path scanner. Wordlist is a text file, each line is a path. About extensions, unlike other tools, dirsearch only replaces the %EXT% keyword with extensions from -e flag. For wordlists without %EXT% (like SecLists), -f | --force-extensions switch is required to append extensions to every word in wordlist, as well as the /. To use multiple wordlists, you can separate your wordlists with commas. Example: wordlist1.txt,wordlist2.txt. Default values for dirsearch flags can be edited in the configuration file: default.conf. The thread number (-t | --threads) reflects the number of separated brute force processes. And so the bigger the thread number is, the faster dirsearch runs. By default, the number of threads is 30, but you can increase it if you want to speed up the progress. -

signal-cli
signal-cli provides a commandline, dbus and JSON-RPC interface
signal-cli is a command line interface for the Signal messenger. It supports registering, verifying, sending and receiving messages. signal-cli uses a patched libsignal-service-java, extracted from the Signal-Android source code. For registering you need a phone number where you can receive SMS or incoming calls. signal-cli is primarily intended to be used on servers to notify admins of important events. For this use-case, it has a daemon mode with D-BUS interface (man page) and JSON-RPC interface (documentation). For the JSON-RPC interface, there's also a simple example client, written in Rust. -

arduino-cli
Arduino command line tool
Arduino CLI is an all-in-one solution that provides Boards/Library Managers, sketch builders, board detection, uploader, and many other tools needed to use any Arduino compatible board and platform from the command line or machine interfaces. In addition to being a standalone tool, Arduino CLI is the heart of all official Arduino development software (Arduino IDE, Arduino Web Editor). The script requires sh, which is always available on Linux and macOS. sh is not available by default on Windows, though it is available as part of Git for Windows (Git Bash). If you don't have sh available, use the "Download" installation option. If you would like to use the arduino-cli command from any location, install Arduino CLI to a directory already in your PATH or add the Arduino CLI installation path to your PATH environment variable.
