Mozilla JPEG Encoder Project
Improved JPEG encoder
MozJPEG improves JPEG compression efficiency achieving higher visual quality and smaller file sizes at the same time. It is compatible with the JPEG standard, and the vast majority of the world's deployed JPEG decoders. MozJPEG is compatible with the libjpeg API and ABI. It is intended to be a drop-in replacement for libjpeg. MozJPEG is a strict superset of libjpeg-turbo's functionality. All MozJPEG's improvements can be disabled at run time, and in that case it behaves exactly like libjpeg-turbo. MozJPEG is meant to be used as a library in graphics programs and image processing tools. We include a demo cjpeg command-line tool, but it's not intended for serious use. We encourage authors of graphics programs to use libjpeg's C API and link with MozJPEG library instead. Progressive encoding with "jpegrescan" optimization. It can be applied to any JPEG file (with jpegtran) to losslessly reduce file size. -

google-java-format
Reformats Java source code to comply with Google Java Style
google-java-format is a program that reformats Java source code to comply with Google Java Style. The formatter can act on whole files, on limited lines, on specific offsets, passing through to standard-out (default) or altered in-place. There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format. The formatter can be used in software that generates java to output more legible java code. Just include the library in your maven/gradle/etc. configuration. A google-java-format IntelliJ plugin is available from the plugin repository. To install it, go to your IDE's settings and select the Plugins category. Click the Marketplace tab, search for the google-java-format plugin, and click the Install button. -

Kryo
Java binary serialization and cloning, fast, efficient, automatic
Kryo is a fast and efficient binary object graph serialization framework for Java. The goals of the project are high speed, low size, and an easy-to-use API. The project is useful any time objects need to be persisted, whether to a file, database or over the network. Kryo can also perform automatic deep and shallow copying/cloning. This is direct copying from object to object, not object to bytes to object. Kryo has three sets of methods for reading and writing objects. If the concrete class of the object is not known and the object could be null. Besides methods to read and write objects, the Kryo class provides a way to register serializers, reads and writes class identifiers efficiently, handles null objects for serializers that can't accept nulls, and handles reading and writing object references (if enabled). This allows serializers to focus on their serialization tasks. -

Mercure
Server-sent live updates, protocol and reference implementation
Mercure is an open protocol for real-time communications designed to be fast, reliable and battery-efficient. It is a modern and convenient replacement for both the WebSocket API and the higher-level libraries and services relying on it. Mercure is especially useful to add streaming and asynchronous capabilities to REST and GraphQL APIs. Because it is a thin layer on top of HTTP and SSE, Mercure is natively supported by modern web browsers, mobile applications, and IoT devices. A free (as in beer, and as in speech) reference server, as well as a hosted service, are available. Designed for REST and GraphQL. Private updates (JWT authorization). Presence API and subscription events. Event store. Compatible with serverless, PHP, and the like. Supports end-to-end encryption. Reading the documentation is an excellent way to discover Mercure. -

NewsBlur
NewsBlur is a personal news reader that brings people together
NewsBlur is an open-source, full-stack RSS news reader and social reading platform with a hosted service and native clients. The backend crawls and parses feeds at scale, stores stories, and pushes updates to users in near real time, while the web app and mobile apps provide rich reading experiences. Its hallmark is “training”: you can tell the system what you like or dislike—authors, keywords, tags—and it prioritizes stories accordingly, surfacing what matters most. Features like saved stories, tagging, full-text search, and offline reading make it practical for heavy information consumers. Social elements allow sharing to your own “blurblog,” following friends, and discovering curated content, which turns a solitary reader into a lightweight network. Architecturally, it demonstrates a production-ready aggregation pipeline, a multi-tenant web app, and cross-platform clients living in one coherent codebase. -

shadowsocks-libev
Bug-fix-only libev port of shadowsocks
Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy. -

iCheck
Highly customizable checkboxes and radio buttons
Highly customizable checkboxes and radio buttons for jQuery and Zepto. jQuery and Zepto JavaScript libraries support from single file. iCheck works with checkboxes and radio buttons like a constructor. It wraps each input with a div, which may be customized by you or using one of the available skins. You may also place inside that div some HTML code or text using insert option. By default, iCheck doesn't provide any CSS styles for wrapper divs (if you don't use skins). HTML5 allows specifying indeterminate ("partially" checked) state for checkboxes. iCheck supports this for both checkboxes and radio buttons. You can make an input indeterminate through HTML using additional attributes (supported by iCheck). Both do the same job, but indeterminate="true" may not work in some browsers (like IE7). iCheck provides plenty callbacks, which may be used to handle changes. -

ISO SAX
Callback-based ISO media file parser
ISO SAX is a callback-based parser for ISO container files (ISO/IEC 14496-12), e.g. MPEG-4. The libraries that are out there either won't run on Android, have many megabytes of dependent JARs, or will fail to parse your favorite media file due to a "technicality" it thinks it is mal-formed. For example, a perfectly good M4B file gets declared "invalid" because it had a video track in it (the album art), along with the sound track. Really!? Don't let these libraries "judge" the format and lock you out! Then there's the obsession with representing every last byte of a media file, when all you want is the metadata.
