    Blooket Cheats

    Blooket Cheats

    05k0nz's legacy is safe

    Blooket-Cheats is a repository containing scripts and a small web interface for Blooket game modifications. It organizes cheat scripts by game mode and provides methods for loading them through bookmarklets, a GitHub Pages interface, or browser console execution. The repository includes folders for cheats, tutorials, auto-update logic, page styling, and front-end code. From a software perspective, it is a browser-script collection focused on manipulating a web game environment. However, using cheats can violate platform rules, undermine fair play, and create problems in classroom or competitive settings. It is best described neutrally as a JavaScript-based browser scripting repository rather than as a recommended gameplay tool.

    LosslessCut

    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

    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.
