AutoAP
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. -

LosslessCut
The swiss army knife of lossless video/audio editing
LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work. Lossless merge/concatenation of arbitrary files (with identical codecs parameters, e.g. from the same camera). Lossless stream editing: Combine arbitrary tracks from multiple files (ex. add music or subtitle track to a video file). -

Arduino IDE
Arduino IDE library
This repository contains the source code of the Arduino IDE 2.x, which is currently in the beta stage. The Arduino IDE 2.x is a major rewrite, sharing no code with the IDE 1.x. It is based on the Theia IDE framework and built with Electron. The backend operations such as compilation and uploading are offloaded to an arduino-cli instance running in daemon mode. This new IDE was developed with the goal of preserving the same interface and user experience of the previous major version in order to provide a frictionless upgrade. If you need assistance, see the Help Center and browse the forum. If you think you found a vulnerability or other security-related bug in this project, please read our security policy and report the bug to our Security Team. The builds are generated every day at 03:00 GMT from the main branch and should be considered unstable. -

Detect It Easy
Program for determining types of files for Windows, Linux and MacOS
Detect It Easy (DiE) is a tool for determining the type and internal features of binary and other file formats. It is widely used by malware analysts, digital forensics investigators, reverse engineers, and security researchers to quickly inspect unknown files and infer their type, architecture, compiler/packer used, and internal structure. DiE supports a large variety of file formats — from common executables (Windows PE, Linux ELF, macOS Mach-O) to archives, mobile packages (APK, IPA), legacy binaries, compressed or packed files, and more — making it a versatile first step in analysis or triage workflows. The tool offers both a graphical user interface as well as a command-line interface, allowing flexible use across environments (desktop, servers, automation). Its detection engine is signature-based, but also includes heuristics that help when signatures are missing or obfuscated. This helps when analyzing packed, compressed, or partially corrupted files. -
