jPDFSecure is a Java library which can digitally sign PDF documents and change security settings on PDF Documents. With jPDFSecure, your application or Java applet can encrypt PDF documents, set permissions and passwords, and create and apply digital signatures. jPDFSecure is optimized for performance and is built on top of Qoppa's proprietary PDF technology, so there is no need for any third party software or drivers. jPDFSecure has a simple interface to load PDF documents from files, network drives, URLs, and even input streams, which can be generated at runtime or come directly from a database. After changing security settings, jPDFSecure can save the document to a file, a java.io.OutputStream, or a javax.servlet.ServletOutputStream when running in a J2EE application server to output the file directly to a browser. jPDFSecure is platform-independent and can be used in any environment which supports Java.
jPDFImages is a Java library to export images from PDF files and import images into PDF files. It can create images from pages in a PDF document and export them as JPEG, TIFF, or PNG images. It can return the image of any page in the document to the host Java application as a BufferedImage for further processing or to save in different formats. It can create documents or add pages to existing documents by importing TIFF, JPEG, and PNG images. After creating or modifying a document, it can save to the local filesystem or to an output stream to be able to serve the document directly to a client browser when working within a J2EE server. jPDFImages is built on top of Qoppa's proprietary PDF technology, so you do not have to install any third party software or drivers. It is also 100% Java, so it is completely platform-independent.
jPDFFields is a Java library for working with interactive PDF forms in both AcroForm and XFA formats. It allows your application to get and set field values, and can import and export to the FDF, XFDF, and XDP formats. It can also "flatten" fields in a document. (Flattening is the process of merging the fields into the PDF content layer so the information is retained, but as static PDF content.) jPDFFields is built on top of Qoppa's proprietary PDF technology, so it is 100% Java and does not require any third party software or drivers.
PyMQI is a Python library for working with WebSphere MQ (formerly known as MQSeries) implementing MQI and PCF protocols. It allows one to connect to queues, put, browse, get messages, and to programmatically administer MQ objects. PyMQI has been used in production environments for several years and is known to work on Linux, Windows, Solaris, AIX, and HP-UX with queue managers running on Linux, Windows, Solarix, AIX, HP-UX, and z/OS mainframe.
VectorGraphics2D can export Java painting operations to Encapsulated PostScript (EPS), Scalable Vector Graphics (SVG), or Portable Document Format (PDF) files. It supports the rendering of all geometric shapes provided by the Java language. More advanced features like transparency or clipping paths can be used as well. It has a very small footprint and can be easily used as a replacement for Java's java.awt.Graphics2D class.
GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
hwloc provides command line tools and a C API to obtain the hierarchical map of key computing elements, such as: NUMA memory nodes, shared caches, processor sockets, processor cores, and processor "threads". hwloc also gathers various attributes such as cache and memory information, and is portable across a variety of different operating systems and platforms. hwloc primarily aims at helping high-performance computing (HPC) applications, but is also applicable to any project seeking to exploit code and/or data locality on modern computing platforms.
Schedule::Cron is a Perl module that provides a simple but complete cron-like scheduler. It can be used for periodically executing Perl subroutines. The philosophy behind Schedule::Cron is to call subroutines periodically from within one single Perl program instead of letting cron trigger several (possibly different) Perl scripts. Everything under one roof. Furthermore, Schedule::Cron provides a mechanism to create crontab entries dynamically, which isn't that easy with cron. It knows about all extensions (at least all extensions the author is aware of, i.e those of "Vixie" cron) for crontab entries like ranges including 'steps', specification of month and days of the week by name, or coexistence of lists and ranges in the same field. It even supports a bit more (like lists and ranges with symbolic names). It has existed since 1999 on CPAN and is successfully used in many projects.
Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
