    WSJT

    WSJT

    Weak signal ham radio communication

    The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation. MAP65 and QMAP are designed for EME at VHF and higher frequencies. MAP65 provides a panoramic, polarization-matching receiver for the Q65 and JT65. modes. QMAP works together with WSJT-X to provide a panoramic receiver for Q65 modes covering a 90 kHz sub-band. Programs WSJT and WSPR are interesting primarily for historical reasons. They are superseded by WSJT-X.

    Blank Grabber

    Blank Grabber

    The most powerful stealer written in Python 3

    Blank Grabber is an archived Python information-stealing malware project presented as a configurable grabber with a graphical builder. The repository lists capabilities related to credential theft, session theft, browser data collection, system information capture, screenshots, webcam capture, persistence, evasion, and exfiltration. Although the README includes an educational disclaimer, the tool’s stated behavior is clearly harmful outside isolated and authorized security research. It should not be used as a normal utility, administration tool, or learning project for general users. The safest way to describe it is as a malware sample for defensive analysis, detection engineering, and awareness of common stealer techniques. It is no longer actively maintained in the original repository.

    qBittorrent RuTracker plugin

    qBittorrent RuTracker plugin

    qBittorrent search engine plugin for rutracker

    qBittorrent RuTracker plugin is a lightweight search engine extension designed to integrate the RuTracker torrent index directly into the qBittorrent client, allowing users to search for torrents without leaving the application interface. The plugin follows qBittorrent’s official search plugin architecture and is implemented as a Python script that communicates with the RuTracker website to retrieve and display search results. By embedding this functionality into the client, it streamlines the torrent discovery process and reduces the need for manual browsing across external websites. The plugin requires users to authenticate with RuTracker credentials, enabling access to content that may otherwise be restricted or hidden behind login requirements. It is designed to be simple to install and configure, typically involving placing the script in the appropriate directory and editing credentials.

    Synapse

    Synapse

    Matrix reference homeserver

    Matrix is an ambitious new ecosystem for open federated Instant Messaging and VoIP. Everything in Matrix happens in a room. Rooms are distributed and do not exist on any single server. Rooms can be located using convenience aliases like #matrix:matrix.org or #test:localhost:8448. Synapse is currently in rapid development, but as of version 0.5 we believe it is sufficiently stable to be run as an internet-facing service for real usage! Create and manage fully distributed chat rooms with no single points of control or failure. Eventually-consistent cryptographically secure synchronization of room state across a global open network of federated servers and services. Send and receive extensible messages in a room with (optional) end-to-end encryption. Use 3rd Party IDs (3PIDs) such as email addresses, phone numbers, Facebook accounts to authenticate, identify and discover users on Matrix.

    smart_open

    smart_open

    Utils for streaming large files (S3, HDFS, gzip, bz2...)

    smart_open is a Python library for streaming very large files from local or remote storage through a familiar file-like interface. It acts as an extended replacement for Python's built-in open function. Supported backends include Amazon S3, Google Cloud Storage, Azure Blob Storage, HDFS, WebHDFS, HTTP, HTTPS, SFTP, and local filesystems. Data can be read or written without first downloading an entire remote object to disk. Transparent compression and decompression are supported for multiple common formats. Standard operations such as context managers, iteration, and supported seek behavior remain available. Optional transport dependencies let installations include only the cloud or protocol integrations an application actually requires.

    Project moved to https://github.com/owfs/owfs/

    Please note that OWFS source code, and all Issue/Tickets/merge requests have now been moved to https://github.com/owfs/owfs/. Developer mailing lists will still be kept at Sourceforge. ---- OWFS -- 1-Wire file system. Use the Dallas 1-Wire and iButton chips with standard filesystem commands. Create temperature loggers. Monitor everything. OWHTTPD -- same system, only used as a light weight web server. OWFS is also ported to embedded routers, Mac OSX and Windows. Basically you can use these inexpensive little sensors and other chips with very simple wiring to sense and control the physical environment. The interface is very flexible -- everything from a web browser, to read and writing directly to the chip's "file" to integrating with your programs -- even over the internet. There is a growing number of 1-wire sensors: temperature, voltage, humidity, light, ultraviolet, pressure, thermisters, thermocouples, programmable microcontrollers, relays, lights, LCD panels, etc

    INTERCEPT

    INTERCEPT

    Unites the best signal intelligence tools

    iNTERCEPT is a web-based interface that brings multiple software-defined radio and signal-intelligence style tools under one consistent dashboard, making complex workflows more approachable. Rather than requiring you to learn a different UI and setup process for each underlying utility, it provides a single place to start modes, view results, and monitor activity from a browser. The project’s goal is accessibility: lowering the skill and setup barrier so learners and authorized testers can explore radio and RF-adjacent analysis with clearer workflows and less tool friction. It emphasizes modular “modes,” letting you focus on a specific type of monitoring or analysis while still benefiting from shared UI patterns and unified configuration. Because it touches sensitive capabilities, the project frames usage around education and authorized testing, encouraging responsible operation and compliance with local laws.
