This bug was initially raised by one of the developers on GCC Bugzilla https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97417 Where for a simple volatile load/store like: gcc will generate: However, the definition of lbu from RISC-V spec mentioned: ” The LW instruction loads a 32-bit value from memory and sign-extends this to 64 bits before storing it in register rd… Read more [GCC] RISC-V: Avoid zero/sign extend for volatile loads.
Momus is a cross-platform image processing tool that designed to counter AI censorship on social media platforms. Momus是一款用来绕过社交平台AI图片匹配的跨平台工具 Github: https://github.com/LevyHsu/Momus Download exe release: https://github.com/LevyHsu/Momus/releases Online Demo: http://direct.momus.levyhsu.com/ Monus uses SIFT（Scale Invariant Feature Transform） from OpenCV to detect all keypoint on the image then inject noise to avoid auto-detection. Monus使用opencv库中的SIFT（Scale Invariant Feature Transform）算法来标记所有的关键点，然后添加噪音来避免社交平台的图片自动匹配。 Library: Install: run:… Read more Momus — An image processing tool
A simple implementation for using Zdns on a Web browser ( ZDNS is a command-line utility that provides high-speed DNS lookups. ) Github: https://github.com/LevyHsu/ZDNS-Flask Although authentication is implemented, it’s still recommended that you use this app on a local network instead of a public network. Also, use it at your own risk! Install Dependencies: sudo… Read more ZDNS-Flask

Requirement: In the system, all the processes are grouped into six priority classes, ranged from 1 to 6, according to their membership status. A larger priority number indicates a higher priority. To maximize the system service performance, you are required to implement a scheduling algorithm using multi-level queue strategy with three queues: : a high… Read more A process scheduling algorithms in C
