    CasADi

    CasADi

    CasADi is a symbolic framework for numeric optimization

    CasADi is a symbolic framework for numeric optimization implementing automatic differentiation in forward and reverse modes on sparse matrix-valued computational graphs. It supports self-contained C-code generation and interfaces state-of-the-art codes such as SUNDIALS, IPOPT, etc. It can be used in C++, Python, or Matlab/Octave. CasADi's backbone is a symbolic framework implementing forward and reverse modes of AD on expression graphs to construct gradients, large-and-sparse Jacobians, and Hessians. These expression graphs, encapsulated in Function objects, can be evaluated in a virtual machine or exported to stand-alone C code. Initial value problems in ordinary or differential-algebraic equations (ODE/DAE) can be calculated using explicit or implicit Runge-Kutta methods or interfaces to IDAS/CVODES from the SUNDIALS suite. Derivatives are calculated using sensitivity equations, up to arbitrary order.

    Cheshire

    Cheshire

    Clojure JSON and JSON SMILE (binary json format) encoding/decoding

    Cheshire is a high-performance JSON encoding and decoding library for Clojure, built atop Jackson to combine fast parsing/generation with advanced support for types like Dates, UUIDs, Sets, Symbols, and the binary JSON SMILE format. Custom encoding is supported from 2.0.0 and up if you encounter a bug, please open a GitHub issue. From 5.0.0 onwards, custom encoding has been moved to be part of the core namespace (not requiring a namespace change). Custom and Core encoding have been combined in Cheshire 5.0.0, so there is no longer any need to require a different namespace depending on what you would like to use. Cheshire will automatically use a BigInteger if needed for non-floating-point numbers.

    CityHash

    CityHash

    Automatically exported from Google code CityHash

    CityHash is a family of non-cryptographic hash functions optimized for extremely fast and high-quality hashing of strings on modern CPUs. Developed by Google, it is implemented in C++ and designed to efficiently handle both short and long inputs using techniques such as mixing operations and CPU-specific optimizations. CityHash offers multiple hash sizes—32-bit, 64-bit, 128-bit, and 256-bit variants—with the CRC-based versions leveraging hardware acceleration on CPUs that support SSE4.2 CRC32 instructions. The library emphasizes hashing performance and uniformity rather than cryptographic security, making it ideal for use in data structures like hash tables and distributed systems requiring rapid key lookups. CityHash has been rigorously tested using tools like SMHasher to ensure high-quality mixing and collision resistance across a wide range of inputs. Its speed and portability have made it a popular choice for developers needing dependable, lightweight hash functions.

    Clean Code PHP

    Clean Code PHP

    Clean Code concepts adapted for PHP

    Clean Code PHP is a coding standard and guideline project aimed at promoting readable, maintainable, and robust PHP across teams and projects. It distills principles like meaningful naming, small functions, single responsibility, error handling, and tests into style rules and examples tailored for PHP’s idioms and language features. Contributors map each guideline to real-world scenarios—refactoring suggestions, before/after code snippets, and edge-case handling—in ways that are directly applicable to legacy and greenfield code. Because PHP is dynamically typed and loosely structured, the project pays special attention to avoiding “magic,” enforcing explicitness, and using type hints and invariants where possible. Its goal isn't to enforce a specific tool or formatting dogma but to raise collective code quality by cultivating shared discipline and vocabulary. By adopting Clean Code PHP employees, teams reduce cognitive debt and make onboarding and code review more consistent.

    Down

    Streaming downloads using Net::HTTP, http.rb or HTTPX

    Down is a small, reliable Ruby library for downloading files that favors correctness, streaming, and clear error handling. It follows redirects safely, supports timeouts and retries, and streams responses to disk to keep memory usage low—ideal for large downloads or server environments. The API returns file-like objects (often Tempfile) with helpful metadata such as original filename and content type, which plays nicely with file-attachment libraries and background jobs. Multiple HTTP backends are supported, letting you choose between Net::HTTP or faster/feature-rich clients while keeping a consistent interface. It exposes distinct exception classes and content validation options, so callers can differentiate transient network issues from invalid responses. In practice, Down is often used as the dependable download layer in upload/processing pipelines where robustness matters more than raw feature bloat.
