PLplot is a library of C functions that are useful for making scientific plots from a program written in C, C++, or Fortran. The PLplot library can be used to create standard x-y plots, semilog plots, log-log plots, contour plots, 3D plots, mesh plots, bar charts and pie charts. Multiple graphs (of the same or different sizes) may be placed on a single page with multiple lines in each graph. Different line styles, widths and colors are supported. A virtually infinite number of distinct area fill patterns may be used. There are almost 1000 characters in the extended character set. This includes four different fonts, the Greek alphabet and a host of mathematical, musical, and other symbols. The fonts can be scaled to any desired size. A variety of output devices are supported and new devices can be easily added by writing a small number of device dependent routines.

"xtail" watches the growth of files. It's like running a "tail -f" on a bunch of files at once. You can specify both filenames and directories on the command line. If you specify a directory, it watches all the files in that directory. It will notice when new files are created (and start watching them) or when old files are deleted (and stop watching them). This program is an oldie but goodie. It was posted to comp.sources.misc in July 1989 (see ftp.uu.net:/usenet/comp.sources.misc/volume7/xtail.Z). I remember posting an even earlier version to alt.sources. It has been published in the O'Reilly & Associates "Unix Power Tools" collection (book and CD-ROM). Over the years, some fly-by-night organizations (such as the MIT X Consortium and SGI) have tried to steal the "xtail" name. Don't be fooled! Insist on the original.

check_multi is kind of a wrapper plugin which takes benefit of the Nagios 3.x capability to display multiple lines of plugin output. It calls multiple child plugins and displays their output in the long_plugin_output. A summary is given in the standard plugin output. The child return code with the highest severity becomes the parent (check_multi) plugin return code. The configuration is very simple: a NRPE-stylish config file contains a tag for each child plugin and then the check command line. check_multi can cover complex Business Process Views - using a builtin state evaluation mechanism. The second benefit is cluster monitoring with no need for extra services. All you need is provided by check_multi. LICENSE: GPL2 or later

This code forms a set of C++ libraries for multimedia streaming, using open standard protocols (RTP/RTCP and RTSP). These libraries - which can be compiled for Unix (including Linux and Mac OS X), Windows, and QNX(and other POSIX-compliant systems) - can be used to build streaming applications. The libraries are already being used to implement applications such as "liveCaster" and "playRTPMPEG" (for streaming MP3 audio using RTP/RTCP). The libraries can also be used to stream, receive, and process MPEG video, and can easily be extended to support additional (audio and/or video) codecs. They can also be used to build basic RTSP clients and servers, and have been used to add streaming support to existing media player applications, such as "mplayer".

This module provides a WebDAV server. WebDAV stands for "Web-based Distributed Authoring and Versioning". It is a set of extensions to the HTTP protocol which allows users to collaboratively edit and manage files on remote web servers. Net::DAV::Server provides a WebDAV server and exports a filesystem for you using the Filesys::Virtual suite of modules. If you simply want to export a local filesystem, use Filesys::Virtual::Plain as above. This module doesn't currently provide a full WebDAV implementation. However, I am working through the WebDAV server protocol compliance test suite (litmus, see http://www.webdav.org/neon/litmus/) and will provide more compliance in future. The important thing is that it supports cadaver and the Mac OS X Finder as clients.

former QueSO home page <URL:http://www.apostols.org/projectz/queso/>: How we can determine the remote OS using simple TCP packets? Well, it's easy, they're packets that don't make any sense, so the RFCs don't clearly state what to answer in these kind of situations. Facing this ambiguous, each TCP/IP stack takes a different approach to the problem, and this way, we get a different response. In some cases (like Linux, to name one) some programming mistakes make the OS detectable. QueSO sends: 0 SYN * THIS IS VALID, used to verify LISTEN 1 SYN+ACK 2 FIN 3 FIN+ACK 4 SYN+FIN 5 PSH 6 SYN+XXX+YYY * XXX & YYY are unused TCP flags All packets have a random seq_num and a 0x0 ack_num.

ubh - the Usenet Binary Harvester - is a GPL'ed Perl console application which automatically discovers, downloads, and decodes single-part and multi-part Usenet binaries. Automatically assembles multi-part binaries. Provides searching via Perl regular expression syntax. Also provides a pre-selection capability whereby the user can interactively choose which binaries to download. Uses a standard .newsrc file to control which groups and articles to process. Runs anywhere Perl runs. Tested under Unix-based Perl, Active Perl on Win32 platforms, and Mac OS X. Requires Net::NNTP and News::Newsrc (which itself requires Set::IntSpan), MIME::Parser, MIME::Base64, IO::Stringy, and MailTools (distribution).

If PDF is electronic paper, then pdftk is an electronic staple-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a simple tool for doing everyday things with PDF documents. Keep one in the top drawer of your desktop and use it to: Merge PDF Documents Split PDF Pages into a New Document Decrypt Input as Necessary (Password Required) Encrypt Output as Desired Burst a PDF Document into Single Pages Report on PDF Metrics, including Metadata and Bookmarks Uncompress and Re-Compress Page Streams Repair Corrupted PDF (Where Possible) Pdftk is also an example of how to use a library of Java classes in a stand-alone C++ program. Specifically, it demonstrates how GCJ and CNI allow C++ code to use iText's (itext-paulo) Java classes.

Orthanc aims at providing a simple, yet powerful standalone DICOM server. It is designed to improve the DICOM flows in hospitals and to support research about the automated analysis of medical images. Orthanc can turn any computer running Windows, Linux, FreeBSD or OS X into a DICOM store (in other words, a mini-PACS system). Its architecture is lightweight and standalone, meaning that no complex database administration is required, nor the installation of third-party dependencies. What makes Orthanc unique is the fact that it provides a RESTful API. Thanks to this major feature, it is possible to drive Orthanc from any computer language. The DICOM tags of the stored medical images can be downloaded in the JSON file format. Furthermore, standard PNG images can be generated on-the-fly from the DICOM instances by Orthanc. Orthanc lets its users focus on the content of the DICOM files, hiding the complexity of the DICOM format and of the DICOM protocol.

HDF5 is a completely new Hierarchical Data Format product consisting of a data format specification and a supporting library implementation. HDF5 is designed to address some of the limitations of the older HDF product and to address current and anticipated requirements of modern systems and applications. HDF5 includes the following improvements: - A new file format designed to address some of the deficiencies of HDF4.x, particularly the need to store larger files and more objects per file. - A simpler, more comprehensive data model that includes only two basic structures: a multidimensional array of record structures, and a grouping structure. - A simpler, better-engineered library and API, with improved support for parallel I/O, threads, and other requirements imposed by modern systems and applications.
