Xapian is an Open Source Probabilistic Information Retrieval library, released
under the GPL. It's written in C++, with bindings to allow use from other
languages.
Xapian is designed to be a highly adaptable toolkit to allow developers to
easily add advanced indexing and search facilities to their own applications.
Xapian features include:
- Ranked probabilistic search - word importance weighting
- Relevance feedback
- Phrase and proximity searching
- Full range of structured boolean search operators
- Term stemming
- Database files > 2GB
- Platform independent data formats
- Allows simultaneous update and searching.
Tile38 is an open source (MIT licensed), in-memory geolocation data store,
spatial index, and realtime geofence. It supports a variety of object types
including lat/lon points, bounding boxes, XYZ tiles, Geohashes, and GeoJSON.
Features:
Spatial index with search methods such as NEARBY, WITHIN, and INTERSECTS.
Realtime geofencing through persistent sockets or webhooks.
Object types of lat/lon, bbox, Geohash, GeoJSON, QuadKey, and XYZ tile.
Support for lots of Clients Libraries written in many different languages.
Variety of client protocols, including http (curl), websockets, telnet,
and the Redis RESP.
Server responses are RESP or JSON.
Full command line interface.
Leader / follower replication.
In-memory database that persists on disk.
KchmViewer is a chm (MS HTML help file format) viewer. Unlike most existing
CHM viewers for Unix, it uses Trolltech's Qt widget library, and does not
depend on KDE or Gnome. However, it may be compiled with full KDE support,
including KDE widgets and KIO/KHTML.
The main advantage of KchmViewer is non-english language support. Unlike
others, KchmViewer in most cases correctly detects help file encoding,
correctly shows tables of context of russian, korean, chinese and japanese
help files, and correctly searches in non-english help files.
Capstone is a lightweight multi-platform, multi-architecture disassembly
framework.
Features:
* Supported architectures: ARM, ARM64 (aka ARMv8), Mips, PowerPC & X86
* Clean/simple/lightweight/intuitive architecture-neutral API
* Provide details on disassembled instruction (called "decomposer")
* Provide some semantics of the disassembled instruction, such as list of
implicit registers read & written.
* Implemented in pure C language, with bindings for Python, Ruby, C#, Java,
GO, OCaml & Vala available.
* Native support for Windows & *nix (including MacOSX, Linux, *BSD & Solaris)
* Thread-safe by design
* Distributed under the open source BSD license

Ccdoc is a tool for extracting comments from C++ source code and presenting it
in HTML format, very similar to Java's JavaDoc tool. The tagging used in ccdoc
is very similar to that of Javadoc, with adaptations for the C++ specifics, of
course. Ccdoc supports extracting comments from both header and implementation
files.
In contrast to most other C++ doc'ing applications, ccdoc analyses the code
before it has been run through the pre-processor, so things such as macros can
actually be included in the documentation.
It's usage is not quite as straight forward as JavaDoc's, but considering the
quality of the output, it is well worth the effort.
The Open On-Chip Debugger (OpenOCD) aims to provide debugging, in-system
programming and boundary-scan testing for embedded target devices. OpenOCD
uses a "hardware interface dongle" to communicate with the JTAG (IEEE 1149.1)
compliant taps on your target board. OpenOCD currently supports many types
of hardware dongles: USB based, parallel port based, and other standalone boxes
that run OpenOCD internally. It allows MIPS, ARM7, ARM9, XScale and Cortex
based cores to be debugged via the GDB protocol. Flash writing is supported
for external CFI compatible NOR flashes, NAND and several internal flashes.
The Embedded Multicore Building Blocks (EMBB) are an easy to use yet
powerful and efficient C/C++ library for the development of parallel
applications. EMBB has been specifically designed for embedded systems and
the typical requirements that accompany them, such as real-time capability
and constraints on memory consumption. As a major advantage, low-level
operations are hidden in the library which relieves software developers
from the burden of thread management and synchronization. This not only
improves productivity of parallel software development, but also results
in increased reliability and performance of the applications.
Fujaba Tool Suite 4
The primary topic of the Fujaba Tool Suite project is to provide an easy to
extend UML and Java development platform with the ability to add plug-ins.
* Fujaba Tool Suite combines UML class diagrams and UML behaviour diagrams to
a powerful, easy to use, yet formal system design and specification language.
* Furthermore the Fujaba Tool Suite supports the generation of Java sourcecode
out of the whole design which results in an executable prototype, ideally.
* Moreover the way back is provided, too (to some extend so far), so that Java
sourcecode can be parsed and represented within UML.
Go-MySQL-Driver is a lightweight and fast MySQL-Driver for Go's
(golang) database/sql package
Features:

* Connections over TCP/IPv4, TCP/IPv6 or Unix domain sockets
* Automatic handling of broken connections
* Automatic Connection Pooling (by database/sql package)
* Supports queries larger than 16MB
* Full sql.RawBytes support.
* Intelligent LONG DATA handling in prepared statements
* Secure LOAD DATA LOCAL INFILE support with file Whitelisting and io.Reader
support
* Optional time.Time parsing
