Dennis Ritchie Personal life Career In 1967, Ritchie began working at the Bell Labs Computing Sciences Research Center, and in 1968, he received a PhD from Harvard under the supervision of Patrick C. Fischer, his doctoral dissertation being "Program Structure and Computational Complexity". The C language is widely used today in application, operating system, and embedded system development, and its influence is seen in most modern programming languages. Unix has also been influential, establishing concepts and principles that are now precepts of computing. Views on computing In an interview from 1999, Dennis Ritchie clarifies that he sees Linux and BSD operating systems as a continuation of the basis of the Unix operating system, and as derivatives of Unix: I think the Linux phenomenon is quite delightful, because it draws so strongly on the basis that Unix provided.

Installing an XSLT processor This section describes how to install the free processors. The commercial processors are assumed to provide instructions and support. You should check the details with each product that is described here, as the steps may change over time. The installation of xsltproc is platform dependent since it is a compiled C program. Installing xsltproc on Windows You can download precompiled versions for Windows from Igor Zlatkovic's website: That page also describes how to install the files and use xsltproc on Windows. Once you have unpacked them, your environment's PATH variable must include the locations of the command files like xsltproc.exe and the set of library files named with the .dll suffix. You will know it is working if you can execute the following command in a Command shell to list the version information: xsltproc -version Installing xsltproc on Cygwin Cygwin is a Linux-like environment that runs on Windows.

Unix Unix (all-caps UNIX for the trademark) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Many clones of Unix have arisen over the years, of which Linux is the most popular, having overtaken the popularity of "true" Unix on server platforms since its inception in the early 1990s. Overview Originally, Unix was meant to be a programmer's workbench to be used for developing software to be run on multiple platforms more than to be used to run application software. History The history of Unix dates back to the mid-1960s when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were developing an experimental time sharing operating system called Multics for the GE-645 mainframe. Multics introduced many innovations, but had many problems. Standards Components
Comparing XSLT 1.0 and XSLT 2.0 undefined Comparing XSLT 1.0 and XSLT 2.0 In this article, I shall compare the XSLT 1.0 and XSLT 2.0 programming languages. How old are these two languages, and a little bit of history? Changes at a glanceFollowing are the major differences between XSLT 1.0 and XSLT 2.0. 1) Schema Awareness: XSLT 2.0 defines two (conformance) levels for the language. 2. 3. 4. 5. 6. 7. 8. xsl:function instruction: XSLT 2.0 supports a new instruction, called xsl:function which allows user-defined functions to be used in XPath expressions. 9. 10. 11. I have tried to convey the feel of differences between XSLT 1.0 and XSLT 2.0. My overall feeling is, XSLT 2.0 is a big step forward, and should be adopted as widely as possible. References:1) 2) 3) 4) gNewSense gNewSense takes a relatively strict stance against proprietary software. For example, any documentation that gives instructions on installing proprietary software is excluded. gNewSense is the distribution used by Richard Stallman (founder and president of the Free Software Foundation) as of January 2010. History The project was launched by Brian Brazil and Paul O'Malley in 2006. Since the 1.0 release, the Free Software Foundation assists gNewSense. With no releases in two years, on 8 August 2011, Distrowatch classified gNewSense as "dormant". Technical aspects gNewSense logo, used from 2007 to 2013 By default gNewSense uses GNOME, the official desktop environment of the GNU Project. Installation The Live CD can be used to run the Operating System and to install onto disk. Versions gNewSense has made three major releases (TBA stands for to be announced): Comparison with other distributions Limitations Reception See also References
Saxon Running XSLT from the Command Line A command is available to apply a given stylesheet to a given source XML document. For simple transformations on the Java platform, use the command: java net.sf.saxon.Transform -s:source -xsl:stylesheet -o:output where source, stylesheet, and output are the source XML file, the XSLT stylesheet,B and the output file respectively. For the .NET platform, the command is simply: Transform -s:source -xsl:stylesheet -o:output For a schema-aware transformation, specify the option -sa, or (on the Java platform only) use the alternate entry point com.saxonica.Transform. For backwards compatibility with previous releases, the prefixes "-s:" and "-xsl:" can be omitted provided that the source document and the stylesheet are the last two options before any keyword=value parameters. For this to work, all the necessary Java components must be available on the classpath. If you are are not using any additional Java libraries, you can use the simpler form of command (this example is for the Home Edition): <?
Steve Perlman Perlman’s technology work is built into all iPhones, video iPods, Macs and most PCs, and has been deployed by DirecTV, Dish, Comcast, Time Warner, Charter and Adelphia cable TV and satellite TV networks. Consumer products incorporating Perlman’s work have also been retailed by Sony, Philips, RCA, Panasonic, Mitsubishi, Samsung, Fujitsu, Motorola, Scientific Atlanta, Sega and Nintendo. Perlman’s recently patented facial motion capture technology, Mova Contour, was used for the production of the Academy Award-winning photoreal computer-generated face of Brad Pitt in “The Curious Case of Benjamin Button” (2008), and of Edward Norton and Tim Roth in “The Incredible Hulk” (2008). Perlman holds over 100 US patents, and has more than 100 additional patents pending. He is a graduate of Columbia University. Working biography Perlman built his first computer from a kit during high school in 1976. In 1983-1984, Perlman designed a parallel-processing graphics system at Atari.
XQuery 1.0 and XPath 2.0 Data Model (XDM) (Second Edition) This section describes the constraints on instances of the data model. This document describes how to construct an instance of the data model from an infoset ([Infoset]) or a Post Schema Validation Infoset (PSVI), the augmented infoset produced by an XML Schema validation episode. An instance of the data model can also be constructed directly through application APIs, or from non-XML sources such as relational tables in a database. The data model supports some kinds of values that are not supported by [Infoset]. 3.3 Construction from a PSVI An instance of the data model can be constructed from a PSVI, whose element and attribute information items have been strictly assessed, laxly assessed, or have not been assessed. Data model construction requires that the PSVI provide unique names for all anonymous schema types. The data model supports incompletely validated documents. 3.3.1 Mapping PSVI Additions to Node Properties 220.127.116.11 Element and Attribute Node Type Names 18.104.22.168 Pattern Facets year

XSL Transformations (XSLT) Version 2.0 This section provides a checklist of progress against the published XSLT 2.0 Requirements document (see [XSLT 2.0 Requirements]). Requirement 1 must Maintain Backwards Compatibility with XSLT 1.1 [Read this as "with XSLT 1.0"] Any stylesheet whose behavior is fully defined in XSLT 1.0 and which generates no errors will produce the same result tree under XSLT 2.0 Response See J.1 Incompatible Changes Requirement 2 must Match Elements with Null Values A stylesheet should be able to match elements and attributes whose value is explicitly null. This has been handled as an XPath 2.0 requirement. Requirement 3 should Allow Included Documents to "Encapsulate" Local Stylesheets XSLT 2.0 should define a mechanism to allow the templates in a stylesheet associated with a secondary source document, to be imported and used to format the included fragment, taking precedence over any applicable templates in the current stylesheet. Requirement 4 Could Support Accessing Infoset Items for XML Declaration
