QOwnNotes
QOwnNotes is a plain-text file notepad and todo-list manager
QOwnNotes is a fully open-source markdown-focused note-taking and personal information manager that runs natively on Linux, macOS, and Windows, with a strong emphasis on plain-text storage and cross-device synchronization. Because all notes are stored as markdown files in user-controlled directories, you avoid vendor lock-in and can sync through services like Nextcloud, ownCloud, Dropbox, or Git without proprietary cloud dependency. The application is optimized for performance and minimal footprint, so it runs smoothly even with large note libraries, and it includes features like a live markdown preview panel that lets you see rendered text alongside raw markdown as you type. QOwnNotes supports hierarchical folders and tagging, making it easy to organize, filter, and retrieve information quickly, and it also integrates to-do lists and task markers directly in your notes. -

Souper
A superoptimizer for LLVM IR
Souper is a superoptimizer for LLVM IR designed to automatically discover missed optimization opportunities within LLVM’s mid-end optimizers. By leveraging SMT (Satisfiability Modulo Theories) solvers, Souper symbolically analyzes LLVM Intermediate Representation (IR) to synthesize equivalent, more efficient expressions. It identifies peephole optimizations—small instruction-level improvements—that LLVM’s optimizer may overlook, thereby improving compiled code quality. Souper can operate in multiple modes: as a standalone analysis tool that extracts and solves SMT queries from LLVM bitcode, or as an LLVM optimization pass that applies discovered optimizations directly to the IR. It integrates seamlessly with Clang and LLVM tools and supports caching mechanisms (RAM or Redis) to accelerate repeated analyses. The system can output suggested rewrites for developers or automatically apply transformations, helping compiler engineers improve optimization passes. -

rims-arduino-library
Recirculation infusion mash system library for Arduino
This library implement RIMS controls for home brewers. For definition of a RIMS, see https://tinyurl.com/j3lyuyc For me, an Arduino micro controller + a LCD Keypad shield was cheaper and a lot more customizable than a commercial PID controller. So, with this library, a commercial PID controller is unnecessary. Automatic PID tuning toolkit is also included. Temperature can be read with a thermistor, a resistance temperature detector (RTD) or any custom temperature probe. Heater is controlled with pulse-width modulation (PWM) of a solid-state relay (SSR). Documentation : https://tinyurl.com/y7579v6a -
