    EmojiOne Color SVGinOT Font

    EmojiOne Color SVGinOT Font

    A color and B&W emoji SVGinOT font built from EmojiOne artwork with support for ZWJ, skin tone diversity and country flags. The font works in all operating systems, but will currently only show color emoji in Firefox, Thunderbird, Photoshop CC 2017, and Windows Edge V38.14393+. This is not a limitation of the font, but of the operating systems and applications. Regular B&W outline emoji are included for backward/fallback compatibility. SVG in Open Type is a standard by Adobe and Mozilla for color OpenType and Open Font Format fonts. It allows font creators to embed complete SVG files within a font enabling full color and even animations. There are more details in the SVGinOT proposal and the OpenType SVG table specifications. The default serif, sans-serif and monospace font for most Linux distributions is DejaVu. DejaVu includes a wide range of symbols that override the EmojiOne Color characters.

    Shaderc

    Shaderc

    A collection of tools, libraries, and tests for Vulkan shader

    Shaderc is a collection of tools and libraries for compiling shaders—small programs that run on GPUs—into SPIR-V, the intermediate representation used by the Vulkan graphics API. It provides both a command-line tool (glslc) and a C/C++ library (libshaderc) that wrap the functionality of glslang (the Khronos reference compiler for GLSL) and SPIRV-Tools to deliver a modern, scriptable, and efficient shader compilation workflow. The glslc compiler offers a GCC/Clang-like interface for building GLSL and HLSL shaders, making it easy to integrate into existing build systems. Meanwhile, libshaderc exposes a stable API that allows developers to programmatically compile shader strings into SPIR-V modules within graphics engines and tools. Shaderc supports advanced features such as file inclusion (#include), concurrency, and cross-platform builds, and it maintains backward compatibility for long-term projects.

    NSync

    NSync

    nsync is a C library that exports various synchronization primitives

    nsync is a portable C library that provides a collection of advanced synchronization primitives designed to facilitate safe and efficient multithreaded programming. It offers reader-writer locks, condition variables, run-once initialization, waitable counters, and waitable bits for coordination and cancellation between threads. Unlike traditional pthreads-based synchronization, nsync introduces conditional critical sections, allowing developers to wait for arbitrary conditions without explicit signaling or complex loop-based logic. This approach simplifies concurrency management and often improves readability and maintainability of multithreaded code. The library emphasizes efficiency, with locks and condition variables occupying minimal memory and supporting cancellation mechanisms through nsync_note objects rather than thread-level cancellation. Designed with portability and performance in mind, nsync can be compiled on Unix-like systems and Windows using a C90 compiler.

    Certificate Transparency Go

    Certificate Transparency Go

    Auditing for TLS certificates (Go code)

    certificate-transparency-go is a Go codebase for building and interacting with Certificate Transparency (CT) systems, from low-level parsing to full log operation. It includes forked ASN.1 and X.509 packages tailored to accept and analyze real-world certificates, including pre-certificates that stricter libraries would reject, supporting CT’s role as an ecosystem observatory. A TLS parsing library, CT data types, and multiple client libraries enable access to CT logs over HTTP and DNS, along with scanners for traversing entire logs. The repository also provides command-line tools for verifying signed certificate timestamps, inspecting certificates and CRLs, and querying logs. For operators, a “CT personality” integrates with Trillian so you can run a CT log backed by a verifiable transparency log. The project is structured for contributors, with generators, mocks, linting, and presubmit tooling to keep changes consistent and reliable.

    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.

    AWS CodeBuild curated Docker images

    AWS CodeBuild repository for managed Docker images

    When you call AWS CodeBuild to run a build, you must provide information about the build environment. A build environment represents a combination of operating system, programming language runtime, and tools that CodeBuild uses to run a build. The master branch will sometimes have changes that are still in the process of being released in AWS CodeBuild. When you provide information to CodeBuild about the build environment, you specify the identifier of a Docker image in a supported repository type. These include the CodeBuild Docker image repository, publicly available images in Docker Hub, and Amazon Elastic Container Registry (Amazon ECR) repositories that your AWS account has permission to access. We recommend that you use Docker images stored in the CodeBuild Docker image repository, because they are optimized for use with the service.

    A modern standard library / framework / boilerplate for Bash

    Bash Infinity is a standard library and a boilerplate framework for writing tools using bash. It's modular and lightweight while managing to implement some concepts from C#, Java or JavaScript into bash. The Infinity Framework is also plug & play: include it at the beginning of your existing script to import any of the individual features such as error handling, and start using other features gradually. The aim of Bash Infinity is to maximize the readability of bash scripts, minimize the amount of code repeat and create a central repository for a well-written, and a well-tested standard library for bash. Bash Infinity transforms the often obfuscated "bash syntax" to a cleaner, more modern syntax. Some components are more sturdy than others, and as-it-stands the framework lacks good test coverage (we need your help!).
