LeakCanary
A memory leak detection library for Android
LeakCanary is a reliable memory leak detection library for Android. It effectively detects leaks and narrows down the cause of each leak through its in-depth knowledge of the internals of the Android Framework. This helps developers avoid and dramatically reduce OutOfMemoryError (OOM) crashes. A memory leak is a programming error that can cause an OutOfMemoryError crash. It’s often caused by bugs related to the lifecycle of objects, and can occur fairly often in Android applications. LeakCanary helps to find and fix those leaks during development so you never have to experience another OOM crash. -

Moment.js
Parse, validate, manipulate, and display dates in javascript
Moment is a JavaScript date and time library that simplifies parsing, formatting, arithmetic, and humanizing of dates. It supports many formats in input and output, internationalization (i18n), locale-based month/day names, relative time (for example, “3 days ago”), and chaining of operations (adding, subtracting, diffing). Developers often use it for calendar displays, scheduling, and manipulating times across time zones or daylight saving transitions. While it makes working with date strings convenient, moment maintains internal mutability, which has trade-offs with safety and chainability. Over time, newer alternatives with immutable and modular designs have emerged, but moment remains widely known and integrated in many legacy projects. Its comprehensive feature set and ease of use made it a standard for date-time handling in JavaScript for many years. -

Particle Firmware for the Electron, P1
Device OS (Firmware) for particle devices
The Photon uses an ARM Cortex M3 CPU based microcontroller. All of the code is built around the GNU GCC toolchain offered and maintained by ARM. The build requires version 5.3.1 20160307 or newer of ARM GCC and will print an error message if the version is older than this. In order to turn your source code into binaries, you will need a tool called make. Windows users need to explicitly install make on their machines. Make sure you can use it from the terminal window. The entire Particle firmware is contained in this repository. The main user code sits in the application.cpp file under firmware/user/src/ folder. Unless you know what you are doing, refrain from making changes to any other files. After you are done editing the files, you can rebuild the repository by running the make command in the firmware/main/ directory. If you have made changes to any of the other directories, make automatically determines which files need to be rebuilt and builds them for you. -

Piranha
A tool for refactoring code related to feature flag APIs
Feature flags are commonly used to enable gradual rollout or experiment with new features. In a few cases, even after the purpose of the flag is accomplished, the code pertaining to the feature flag is not removed. We refer to such flags as stale flags. The presence of code pertaining to stale flags can have the following drawbacks. Unnecessary code clutter increases the overall complexity w.r.t maintenance resulting in reduced developer productivity The flags can interfere with other experimental flags (e.g., due to nesting under a flag that is always false) Presence of unused code in the source as well as the binary. Stale flags can also cause bugs. Piranha is a tool to automatically refactor code related to stale flags. At a higher level, the input to the tool is the name of the flag and the expected behavior, after specifying a list of APIs related to flags in a properties file. -

Polly
A .NET resilience and transient-fault-handling library for policies
Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+. Today's cloud application, mobile, data-streaming, and IoT technologies all depend vitally on reliable connectivity. But underlying systems can fail, and networks are notoriously fickle, outages, latency, transient blips, spikes in load, all challenge 100% reliability. Polly helps you navigate the unreliable network. By providing resilience strategies in fluent-to-express policies such as Retry, WaitAndRetry, and CircuitBreaker, Polly can help you reduce fragility, and keep your systems and customers connected. Example usages are fault-tolerance for any distributed systems and inter-process calls, such as WCF, RESTful calls between microservices, calls to cloud services, Internet of Things connectivity, etc. -

ProbabilisticCircuits.jl
Probabilistic Circuits from the Juice library
This module provides a Julia implementation of Probabilistic Circuits (PCs), tools to learn structure and parameters of PCs from data, and tools to do tractable exact inference with them. Probabilistic Circuits provides a unifying framework for several family of tractable probabilistic models. PCs are represented as computational graphs that define a joint probability distribution as recursive mixtures (sum units) and factorizations (product units) of simpler distributions (input units). Given certain structural properties, PCs enable different range of tractable exact probabilistic queries such as computing marginals, conditionals, maximum a posteriori (MAP), and more advanced probabilistic queries. -

Python Progressbar
Progressbar 2 - A progress bar for Python 2 and Python 3
A text progress bar is typically used to display the progress of a long-running operation, providing a visual cue that processing is underway. The progressbar is based on the old Python progressbar package that was published on the now-defunct Google Code. Since that project was completely abandoned by its developer and the developer did not respond to my email, I decided to fork the package. This package is still backward compatible with the original progressbar package so you can safely use it as a drop-in replacement for existing projects. The ProgressBar class manages the current progress, and the format of the line is given by a number of widgets. A widget is an object that may display differently depending on the state of the progress bar. -

RealWorld
Exemplary fullstack Medium.com clone powered by React, Angular, Node
RealWorld is the “mother of all demo apps”—a full spec and starter backend/frontend that implements a Medium-like blogging platform to showcase best practices across many frameworks. Instead of trivial todo lists, it provides a realistic feature set: authentication, CRUD operations, pagination, comments, profiles, tagging, and favoriting. The same spec is realized dozens of times (React, Vue, Svelte, Angular, Solid, Next, Remix, and many more), alongside multiple server implementations, so learners can compare idioms without guessing about feature gaps. A shared API contract and test suite keep implementations consistent and reveal framework-specific tradeoffs clearly. This makes the repo a powerful teaching tool for architecture, state management, testing, and deployment patterns at production scale. Teams also use it to evaluate new frameworks by building “yet another RealWorld” and measuring DX, bundle size, and maintainability. -
