    Big List of Naughty Strings

    Big List of Naughty Strings

    List of strings which have a high probability of causing issues

    The Big List of Naughty Strings is a community-maintained catalog of “gotcha” inputs that commonly break software, from unusual Unicode to SQL and script injection payloads. It exists so developers and QA engineers can easily test edge cases that normal test data would miss, such as zero-width characters, right-to-left marks, emojis, foreign alphabets, and long or malformed strings. By throwing these strings at forms, APIs, databases, and UIs, teams can discover encoding bugs, sanitizer gaps, rendering issues, and security oversights early. The list is language-agnostic and repository-friendly, meaning you can consume it from CI pipelines or local scripts with minimal setup. Because it’s crowdsourced, it reflects real issues practitioners have faced in production, not just theoretical cases. Using the list regularly helps harden applications against the fragile edges of text processing and user input.

    Binding.scala

    Binding.scala

    Reactive data-binding for Scala

    Binding.scala is a data-binding library for Scala, running on both JVM and Scala.js. Binding.scala can be used as the basis of UI frameworks, however latest Binding.scala 12.x does not contain any build-in UI frameworks anymore. For creating reactive HTML UI, you may want to check out html.scala, which is a UI framework based on Binding.scala, and it is also the successor of the previously built-in dom library. See also React / Binding.scala / html.scala Interoperability for using existing React components with Binding.scala. Regular HTML does not compile unless developers manually replace class and for attributes to className and htmlFor, and manually convert inline styles from CSS syntax to JSON syntax.

    Bloaty

    Bloaty

    Bloaty: a size profiler for binaries

    Bloaty is a deep, accurate size profiler for native binaries that tells you where every byte comes from so you can shrink executables and libraries intelligently. It parses binary formats like ELF, Mach-O, and DWARF symbol/debug data without relying solely on toolchain heuristics, letting you attribute size to files, sections, symbols, templates, and even compilation units. Reports can be produced at multiple granularities and diffed across builds to identify regressions introduced by compiler flags, dependencies, or new code paths. The tool is designed to be fast enough for iterative use in developer workflows and CI, making size budgets enforceable rather than aspirational. It also supports data sources such as symbol tables and map files, combining them into coherent, readable breakdowns. Teams use Bloaty to drive systematic size-reduction efforts in embedded, desktop, and mobile software where startup time, memory footprint, or download size matter.

    Bluebird

    Bluebird

    Full featured promise library with unmatched performance

    Bluebird is a fully featured promise library with focus on innovative features and performance. Promises in Node.js 10 are significantly faster than before. Bluebird still includes a lot of features like cancellation, iteration methods and warnings that native promises don't. If you are using Bluebird for performance rather than for those - please consider giving native promises a shot and running the benchmarks yourself. When using script tags the global variables Promise and P (alias for Promise) become available. Bluebird runs on a wide variety of browsers including older versions. Synchronous inspection allows you to retrieve the fulfillment value of an already fulfilled promise or the rejection reason of an already rejected promise synchronously. The default approach of bluebird is to immediately log the stack trace when there is an unhandled rejection.

View the showcase demo to see the buttons in action. The showcase provides a full list of examples along with code snippets to speed up development. If you're using Bower you can run bower install Buttons. Buttons styles are now independent (ex. button-flat, button-3d, etc.). You can apply these styles and they will automatically pick up the color attached to the button (ex. button-primary button-3d). Button colors are now completely independent (ex. button-primary). We no longer have classes like button-flat-primary, so to achieve this you now simply add button-flat button-primary. To edit Buttons simply change values within the _options.scss file. After you make your edits recompile your sass file and your changes will get processed.

    C3.js

    A D3-based reusable chart library

    C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more. C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3. C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered. C3 enables deeper integration of charts into your application. Because of the dependence on D3, C3 supports only modern browsers D3 supports. For IE9 and IE10, polyfill is required because c3 uses MutationObserver, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by bindto because MutationObserver is not called in that case.

    A cross platform C99 library to get cpu features at runtime

    cpu_features is a cross-platform C library developed by Google that provides a simple and efficient way to detect available CPU features at runtime across a wide range of architectures and operating systems. It enables applications to determine which instruction sets (such as SSE, AVX, or NEON) are supported on the host machine, allowing developers to optimize performance dynamically. The library supports numerous architectures—including x86, ARM, AArch64, MIPS, POWER, RISCV, LoongArch, and s390x—and works on major operating systems like Linux, macOS, Windows, FreeBSD, Android, and iOS. Implemented in portable C99, it is thread-safe, has no memory allocations, and raises no exceptions, making it suitable even for use in low-level system libraries. The design emphasizes portability, extensibility, and compatibility with sandboxed or restricted environments where direct CPU access may be limited.

    CUDA Core Compute Libraries (CCCL)

    CUDA Core Compute Libraries

    CCCL, or CUDA Core Compute Libraries, is a unified repository that consolidates several foundational CUDA C++ libraries into a single, cohesive development platform. It brings together Thrust, CUB, and libcudacxx, which collectively provide high-level abstractions, low-level performance primitives, and a CUDA-compatible standard library for GPU programming. The goal of CCCL is to simplify CUDA development by offering reusable building blocks that enable developers to write efficient and scalable parallel code without starting from scratch. Thrust provides a high-level interface for parallel algorithms, while CUB delivers highly optimized primitives for device-level operations, and libcudacxx ensures compatibility with modern C++ standards. By unifying these components, CCCL reduces duplication and improves developer productivity while maintaining performance across different GPU architectures.

    CXX

    CXX

    Safe interop between Rust and C++

    CXX is a library that offers safe interop between Rust and C++. It provides a safe mechanism for calling C++ code from Rust and vice versa, one that is protected from the many possible things that can go wrong when bindgen or cbindgen is used to generate unsafe C-style bindings. The general idea of CXX is to define the signatures of both sides of the FFI boundary embedded together in one Rust module. CXX gets a complete picture from this of the boundary, and through it is able to perform static analyses against the types and function signatures, ensuring that both Rust's and C++'s invariants and requirements are upheld. CXX then emits the relevant extern "C" signatures on both sides through a pair of code generators. This is done together with any necessary static assertions needed for later in the build process to verify correctness. The result is an FFI bridge that operates at zero or negligible overhead, with no copying, serialization or memory allocation needed.

    Cats-Effect is a high-quality functional programming library for Scala that provides a principled way to represent and manage side effects, particularly asynchronous and concurrent computations. It is part of the broader Typelevel ecosystem and builds on the abstractions from Cats (such as Functor, Monad, etc.). The core abstraction is the IO type (or effect types more generally), which encodes effectful computations in a pure, referentially transparent way. Cats-Effect offers capabilities like deferred execution, cancellation, resource safety (Resource), fiber concurrency (lightweight threads), and interoperation with underlying runtime platforms (JVM, Java concurrency, etc.). It enables developers to write effectful code while preserving composability, purity, and modular reasoning about side effects.
