The Oracle (formerly Sun) Java Platform, Standard Edition (Java SE or JSE) allows you to develop and deploy Java applications on desktops and servers as well embedded and real-time environments. The Java Development Kit (JDK) contains the essential compiler, tools, runtime libraries, and APIs for developers writing, deploying, and running applets and applications in the Java programming language. The Java Runtime Environment (JRE) contains the runtime libraries and tools for running applets and applications.
SymmetricDS provides file and database synchronization with support for multi-master replication, filtered synchronization, and transformation across the network in a heterogeneous environment. It supports multiple subscribers with one-direction or bi-directional, asynchronous data replication. It uses Web and database technologies to replicate data as a scheduled or near-realtime operation. The software has been designed to scale for a large number of nodes, work across low-bandwidth connections, and withstand periods of network outage. It works with most operating systems, file systems, and databases, including Oracle, MySQL, MariaDB, PostgreSQL, MS SQL Server (including Azure), IBM DB2, H2, HSQLDB, Derby, Firebird, Interbase, Informix, Greenplum, SQLite (including Android), Sybase ASE, and Sybase ASA (SQL Anywhere) databases.
zlib is designed to be a free, general-purpose, legally unencumbered, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1), the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.
Barcode Writer in Pure Postscript implements the printing of many barcode formats entirely within PostScript, so that the process of converting the input string into the printed output is performed by the printer or print system. The project supports all major barcode formats including: EAN-13 (JAN-13), EAN-8 (JAN-8), UPC-A, UPC-E, EAN-5 & EAN-2 (EAN/UPC add-ons), ISBN (including legacy ISBN), ISMN (including legacy ISMN), ISSN, Code 128 (A, B & C), GS1-128, SSCC-18 (EAN-18, NVE), EAN-14, Code 39, Code 39 Extended, Code 93, Code 93 Extended, Code 32 (Italian Pharmacode), Pharmazentralnummer (PZN), Interleaved 2 of 5, ITF-14 (UPC SCS), GS1 DataBar (Omnidirectional, Stacked, Stacked Omnidirectional, Limited, Expanded, Expanded Stacked), Code 2 of 5 (Industrial, IATA, Matrix, Datalogic & COOP), Code 11 (USD-8), BC412, Codabar (NW-7), Pharmacode (including two-track), MSI, Plessey, Telepen, Channel Code, PosiCode, PDF417, Data Matrix (ECC200), QR Code (including Micro QR Code), and more.
Libxml2 is the XML C library developed for the Gnome project. The library code is portable (to Linux, Unix, Windows, embedded systems, etc.) and modular; most of the extensions can be compiled out. Libxml2 implements a number of existing standards related to markup languages, including the XML standard, Namespaces in XML, XML Base, Relax NG, RFC 2396, XPath, XPointer, HTML4, XInclude, SGML Catalogs, and XML Catalogs. In most cases, libxml tries to implement the specifications in a relatively strict way. To some extent, it provides support for the following specifications, but doesn't claim to implement them: DOM, FTP client, HTTP client, and SAX2. Support for W3C XML Schemas is in progress. It includes xmllint, a command line XML validator.
Embedthis Appweb is a fast, little embedded Web server. It is unmatched in efficiency and serves pages at native speed, using an event-driven, non-blocking core to serve multiple requests using minimal resources. It has integrated caching and the ESP "C" Web framework. Without compromising performance, it has extensive security controls and a rigorous security sandbox that helps protect the server and mitigate denial-of-service attacks. It is one of the most widely deployed embedded Web servers and is used in networking equipment, telephony, mobile devices, industrial control, and consumer and office equipment, and in high-performance Web services.
SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing and chat services. It can be used to send any kind of messages, in addition to normal text messages, including multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, SHA-2, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.
GNU libmicrohttpd is a small C library for embedding HTTP server functionality into other applications. It is reentrant, fast, supports HTTP 1.1, and permits listening on multiple ports. The API is simple and still powerful enough to allow programmers to use the entire HTTP feature set. SSL/TLS support is available as an option.
