SumatraPDF Reader
Multi-format (PDF, EPUB, MOBI, FB2, CHM, XPS, DjVu) reader for Windows
Sumatra PDF is a free PDF, eBook (ePub, Mobi), XPS, DjVu, CHM, Comic Book (CBZ and CBR) viewer for Windows. Sumatra PDF is powerful, small, portable and starts up very fast. Simplicity of the user interface has a high priority. Portable version is a single executable, can be run from USB drive and doesn't write to registry. For best results use the latest release available as that's what I use and test with. If things don't compile, first make sure you're using the latest version of Visual Studio. To compile you need Visual Studio 2019 16.6 or later. Free Community edition works. -

XClicker
Fast gui autoclicker for x11 linux desktops
XClicker is an open-source, easy-to-use, feature-rich and blazing-fast Autoclicker for linux desktops using x11. It is written in C and uses the gtk framework. The user interface may look different depending on what gtk theme you are using. The highest I have got with it was around 750cps, but that was still with 1-millisecond interval. With 0 millisecond interval, the focused application may freeze. Safe mode, to protect from unwanted behavior. Autoclick with a specified amount of time between each click. Choose mouse button [Left/Right/Middle]. -

TaskExplorer
Powerful system task manager
TaskExplorer is a powerful system task-manager / process-inspector tool designed for Windows that goes well beyond the capabilities of the built-in Task Manager. It provides real-time insights into running processes, threads, open handles, network sockets, memory usage, modules loaded, and more — all in a unified, fast, and efficient GUI. Rather than scattering information across tabs or dialogs, TaskExplorer displays detailed data in a panel layout: when you select a process, the lower panel updates dynamically to show relevant info (threads, handles, sockets, modules, etc.), making deep inspection quick and intuitive. It includes advanced panels: a Thread Panel with stack traces (helpful for diagnosing deadlocks or hangs), a Memory Panel that lets you view or even edit process memory (with search capabilities), a Socket Panel showing open network connections, data rates, pseudo-UDP connections (via ETW), and a Modules Panel listing all loaded DLLs and memory-mapped files. -

Quake III Arena
Quake III Arena GPL Source Release
Quake-III-Arena is the legendary first-person shooter originally released in 1999, and this repository holds its GPL-licensed source code release. By making the engine code fully open under GPL-2.0 (with licensing details regarding some bundled libraries like zlib), it allows the community to build, port, and maintain the engine, ensuring that the game remains playable even decades later. The release includes all major game subsystems: rendering, physics, network code, game logic, and tools (map compilation, asset packing, etc.), enabling full builds on Windows, Linux, macOS — assuming you provide the original game assets. Because the source is available, there are many community forks and improved engine builds (and ports) that modernize graphics, compatibility, input, mod support, and add enhancements while preserving core gameplay. The GPL-based release also enables modders and developers to study and extend the engine for learning, custom mods, or even entirely new games. -

thc-hydra
Shows how easy it would be to gain unauthorized access to a system
Number one of the biggest security holes are passwords, as every password security study shows. This tool is a proof of concept code, to give researchers and security consultants the possibility to show how easy it would be to gain unauthorized access from remote to a system. There are already several login hacker tools available, however, none does either support more than one protocol to attack or support parallelized connects. It was tested to compile cleanly on Linux, Windows/Cygwin, Solaris, FreeBSD/OpenBSD, QNX (Blackberry 10) and MacOS. However the module engine for new services is very easy so it won't take a long time until even more services are supported. Via the command line options you specify which logins to try, which passwords, if SSL should be used, how many parallel tasks to use for attacking, etc. PROTOCOL is the protocol you want to use for attacking, e.g. ftp, smtp, http-get or many others are available. -

GoodbyeDPI
Deep Packet Inspection circumvention utility
This software designed to bypass Deep Packet Inspection systems found in many Internet Service Providers which block access to certain websites. It handles DPI connected using optical splitter or port mirroring (Passive DPI) which do not block any data but just replying faster than requested destination, and Active DPI connected in sequence. These scripts launch GoodbyeDPI in recommended mode with DNS resolver redirection to Yandex DNS on non-standard port (to prevent DNS poisoning). To check if your ISP's DPI could be circumvented, first make sure that your provider does not poison DNS answers by enabling "Secure DNS (DNS over HTTPS)" option in your browser. Most Passive DPI send HTTP 302 Redirect if you try to access blocked website over HTTP and TCP Reset in case of HTTPS, faster than destination website. Packets sent by DPI usually have IP Identification field equal to 0x0000 or 0x0001, as seen with Russian providers. -

jq
Lightweight and flexible command-line JSON processor
jq is like sed for JSON data - you can use it to slice, filter, map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine of the same type, and expect it to work. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect. Data in jq is represented as streams of JSON values - every jq expression runs for each value in its input stream, and can produce any number of values to its output stream. jq filters run on a stream of JSON data. The input to jq is parsed as a sequence of whitespace-separated JSON values which are passed through the provided filter one at a time. The output(s) of the filter are written to standard out, again as a sequence of whitespace-separated JSON data. -
