libjpeg-turbo
SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface. -

OpenGApps
OpenGApps daily releases
The Open GApps Project is an open-source initiative that automates the creation of up-to-date Google Apps packages for Android devices. It provides pre-built packages that are compatible with all major Android versions and hardware platforms. Open GApps packages are DPI-optimized, ensuring better performance and consistency across different screen densities. The project updates Google Apps frequently, with new builds generated nightly when updates are available. Strong compression keeps downloads relatively small, even for full-featured packages. The installer checks device compatibility before making changes to prevent installation issues. Open GApps offers multiple package options, ranging from full Google app bundles to lightweight, minimalist configurations. -

UTM
Virtual machines for iOS and macOS
UTM is a full-featured system emulator and virtual machine host for iOS and macOS. It is based off of QEMU. In short, it allows you to run Windows, Linux, and more on your Mac, iPhone, and iPad. UTM/QEMU requires dynamic code generation (JIT) for maximum performance. JIT on iOS devices requires either a jailbroken device or one of the various workarounds found for specific versions of iOS. UTM SE ("slow edition") uses a threaded interpreter which performs better than a traditional interpreter but still slower than JIT. This technique is similar to what iSH does for dynamic execution. As a result, UTM SE does not require jailbreaking or any JIT workarounds and can be sideloaded as a regular app. -

It emphasizes accessibility by offering multiple subscription addresses and supporting IPv6 sources. The project also suggests compatible software players for iOS, Android, Windows, and smart TVs, ensuring that users can easily set up and play live streams. While updates are “as time allows,” the repository has become a popular community-driven resource for IPTV enthusiasts who want quick access to organized streaming content. -

GmsCore
Free implementation of Play Services
microG GmsCore is a FLOSS (Free/Libre Open Source Software) framework to allow applications designed for Google Play Services to run on systems, where Play Services is not available. The linux-based open-source mobile operating system Android is not only the most popular mobile operating system in the world, it’s also on the way to becoming a proprietary operating system. How is that? While the core operating system is still released as part of the Android Open Source Project, the majority of core apps are not. It gets worse: More and more libraries and APIs are only available on phones that run various Google apps pre-installed, effectively locking third-party apps to the Google ecosystem. For these reasons Android is described as being a “look but don’t touch” kind of open. At this point, several popular open-source applications already require some of Google’s proprietary libraries to be installed. -

Apktool
A tool for reverse engineering Android apk files
A tool for reverse engineering 3rd party, closed, binary Android apps. It can decode resources to nearly original form and rebuild them after making some modifications. It also makes working with an app easier because of the project like file structure and automation of some repetitive tasks like building apk, etc. It is NOT intended for piracy and other non-legal uses. It could be used for localizing, adding some features or support for custom platforms, analyzing applications and much more. The decode option on Apktool can be invoked either from d or decode. In order to run a rebuilt application. You must resign the application. Android documentation can help with this. As you probably know, Android apps utilize code and resources that are found on the Android OS itself. These are known as framework resources and Apktool relies on these to properly decode and build apks. -
