Thick database bindings for MySQL, PostgreSQL and SQLite written in Ada. This is the third release of AdaBase, an abstraction library that provides a consistent interface to multiple database servers. Currently three drivers are provided, MySQL, PostgreSQL and SQLite. It's extensible, so support for other databases such as Firebird, Oracle and MSSQL would be easily possible. AdaBase offers unique features over similar frameworks. For starters, it's limited to database support rather than including many other unwanted components in a "kitchen sink" fashion, and unneeded drivers can be excluded from the library as desired. It's got a developer and commerce friend license (ICS), it comes with good documentation and working examples, and the bindings are thick enough where database server backends can be interchangeable. AdaBase may seem familiar to some users as it was partially inspired by PHP's PDO database framework and is a sequel of sorts to an earlier project by the same author, Pascal Data Objects.

GNU Data Access (GDA) is an attempt to provide uniform access to different kinds of data sources (databases, information servers, mail spools, etc). It is a complete architecture that provides all you need to access your data, defined by a set of CORBA interfaces as generic as possible (but very powerful at the same time) so that any kind of data source can be accessed through them. libgda is an interface to the GDA architecture, providing a nice wrapper around the CORBA interfaces, for both the client and the server parts. It also provides a bunch of tools to help you both in the development and management of your data sources, all done through the GDA model's set of CORBA interfaces. libgda was part of the GNOME-DB project, but has been separated from it to allow non-GNOME applications to be developed based on it.

The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. Furthermore, libevent also support callbacks due to signals or regular timeouts. libevent is meant to replace the event loop found in event driven network servers. An application just needs to call event_dispatch() and then add or remove events dynamically without having to change the event loop. Currently, libevent supports /dev/poll, kqueue(2), event ports, select(2), poll(2) and epoll(4). The internal event mechanism is completely independent of the exposed event API, and a simple update of libevent can provide new functionality without having to redesign the applications. As a result, Libevent allows for portable application development and provides the most scalable event notification mechanism available on an operating system. Libevent can also be used for multi-threaded applications.

Pinba is a statistics server for PHP using MySQL as a read-only interface. It accumulates and processes data sent over UDP by multiple PHP processes and displays statistics in a nice human-readable form of simple "reports", also providing a read-only interface to the raw data to enable generation of more sophisticated reports. With the Pinba extension, users can also measure particular parts of the code using timers with arbitrary tags. Pinba is not a debugging tool in the common sense, since you're not supposed to do debugging on production servers, but its main goal is to help developers to locate bottlenecks in realtime and direct their attention to the code that really needs it.

EventMachine implements a fast, single-threaded engine for arbitrary network communications. It's extremely easy to use in Ruby. EventMachine wraps all interactions with IP sockets, allowing programs to concentrate on the implementation of network protocols. It can be used to create both network servers and clients. To create a server or client, a Ruby program only needs to specify the IP address and port, and provide a Module that implements the communications protocol. Implementations of several standard network protocols are provided with the package, primarily to serve as examples. The real goal of EventMachine is to enable programs to easily interface with other programs using TCP/IP, especially if custom protocols are required.

DHIS Daemon release 5.1 ============================== The server is now modular through the introduction of a services sub-system. DNS updates are no longer part of the main code but are now implemented as a module. The main dhisd process listens to DHIS clients and after authentication marks these with their dynamic IP address. The request is passed to a sub-process through a pipe which implements the services for which the client is subscribed to. Clients may be subscribed to one or more services individually. The sub-engine interface does a basic read from stdin and process. Examples of things DHIS could update: Dns, Firewalls, tunnel servers, relay access lists, etc ... For more information on the services of DHIS, you should look at the official DHIS site: http://www.dhis.org/dhis/services/

The libbind functions have been separated from the BIND suite as of BIND 9.6.0. Originally from older versions of BIND, they have been continually maintained and improved but not installed by default with BIND 9. This standard resolver library contains the same historical functions and headers included with many Unix operating systems. In fact, most implementations are based on the same original code. ISC's libbind provides the standard resolver library, along with header files and documentation, for communicating with domain name servers, retrieving network host entries from /etc/hosts or via DNS, converting CIDR network addresses, performing Hesiod information lookups, retrieving network entries from /etc/networks, implementing TSIG transaction/request security of DNS messages, performing name-to-address and address-to-name translations, and utilizing /etc/resolv.conf for resolver configuration.

IRONSIDES is an authoritative DNS server that is provably invulnerable to many of the problems that plague other servers. It achieves this property through the use of formal methods in its design, in particular the language Ada and the SPARK formal methods tool set. Code validated in this way is provably exception-free, contains no data flow errors, and terminates only in the ways that its programmers explicitly say that it can. These are very desirable properties from a computer security perspective. IRONSIDES is not a complete implementation of DNS. In particular, it does not support zone transfers or recursive queries. It does, however, support a sufficient number of DNS records to be useful as an authoritative DNS server for an enterprise.
