TurboVNC is a high-performance, enterprise-quality version of VNC based on TightVNC, TigerVNC, and X.org. It contains a variant of Tight encoding that is tuned for maximum performance and compression with 3D applications (VirtualGL), video, and other image-intensive workloads. TurboVNC, in combination with VirtualGL, provides a complete solution for remotely displaying 3D applications with interactive performance. TurboVNC's high-speed encoding methods have been adopted by TigerVNC and libvncserver, and TurboVNC is also compatible with any other TightVNC derivative.
TurboVNC forked from TightVNC in 2004 and still covers all of the TightVNC 1.3.x features, but TurboVNC contains numerous feature enhancements and bug fixes relative to TightVNC, and it compresses 3D and video workloads much better than TightVNC while using generally only 5-20% of the CPU time of the latter. Using non-default settings, TurboVNC can also be made to compress 2D workloads as "tightly" as TightVNC.

A script to find open Wi-Fi connections and the strongest signal
AutoAP is a script that continuously scans for open Wi-Fi connections, tests them for validity, and connects to the strongest signal. If the connection is lost, the script scans again and finds the strongest valid signal again, and maintains a continuous connection to the internet in a mobile or portable environment. The script paremeters are highly configurable, including ability to configure secure connections.
AutoAP is an add on to DD-WRT that allows routers to continuously scan for and connect to open (and predefined WEP) wireless networks. Ultimately the goal is to develop an easily deployable firmware that facilitates fast and easy mesh network creation.
Typically, you would use this script on your router while in Repeater Mode, Client Mode, or Client-Bridged Mode.

The Open GApps Project is an open-source initiative that automates the creation of up-to-date Google Apps packages for Android devices. It provides pre-built packages that are compatible with all major Android versions and hardware platforms. Open GApps packages are DPI-optimized, ensuring better performance and consistency across different screen densities. The project updates Google Apps frequently, with new builds generated nightly when updates are available. Strong compression keeps downloads relatively small, even for full-featured packages. The installer checks device compatibility before making changes to prevent installation issues. Open GApps offers multiple package options, ranging from full Google app bundles to lightweight, minimalist configurations.
Open source OSINT tool for gathering data on emails, phones, and IPs
X-osint is an open source intelligence framework designed to collect and analyze publicly available information from multiple sources. It focuses on gathering useful and credible data about entities such as phone numbers, email addresses, and IP addresses using a range of automated OSINT techniques. It provides investigators and researchers with a centralized interface for running information-gathering tasks that would normally require multiple separate tools. X-osint can also perform domain-related reconnaissance activities such as subdomain enumeration, DNS lookups, and host discovery to help identify infrastructure associated with a target. In addition to network and domain intelligence, it includes features for extracting metadata from files or images and analyzing text content to uncover hidden details. X-osint is written primarily in Python and is designed to run in terminal environments, particularly on Linux systems and Termux setups.
Streisand sets up a new server running your choice
Streisand is a tool that automates the deployment of censorship-resistant VPN services on cloud servers. It was created to help users bypass internet censorship and surveillance by quickly setting up secure communication channels without needing deep system administration expertise. With just a cloud provider account and basic Unix command-line knowledge, Streisand can provision a server and configure multiple VPN and proxy protocols almost automatically. This includes OpenVPN, WireGuard, Shadowsocks, OpenConnect, and Tor bridges, often with optional add-ons like obfuscation or stunnel to resist throttling and detection. The result is a private website that hosts client software downloads and setup instructions for easy access. Streisand supports major cloud providers like AWS, Azure, Google Cloud, Linode, DigitalOcean, and Rackspace, while also offering installation options for advanced users with their own servers.
Advanced open source tool for bypassing DPI-based censorship
Zapret is an open source, cross-platform tool designed to help users bypass and evade Deep Packet Inspection (DPI)-based traffic blocking and censorship systems. Rather than acting as a traditional proxy or VPN, it works by manipulating network packets and traffic streams locally to confuse or disrupt DPI mechanisms used by ISPs and network filters, making it possible to access restricted websites and services without relaying traffic through third-party servers. Zapret implements multiple strategies including desynchronizing DPI inspection, packet modification, and protocol manipulation to make network traffic less recognizable or harder for DPI systems to classify reliably. It supports deployment on a variety of operating systems including traditional Linux systems, embedded devices like routers running OpenWRT, and has partial support for FreeBSD, OpenBSD, macOS, and Windows.
Fedora-based Linux for developers. Local AI and dev tools built in.
