Exploring the History of the Silicon Chip

A few weeks back I visited the Intel Musuem along with my colleagues Sumedha and Nuwan. The museum is located at Intel’s headquarters in Santa Clara, California- the heart of Silicon Valley. It showcases Intel’s products and processes while giving a deep insight to the history of microprocessors. They exhibit almost all their land mark processor designs from the past, equipment and materials used to manufacture silicon chips and some of Intel’s innovative creations such as ‘Arti’ the talking robot.
Here are some of my favorite pictures from the trip....

The Apache Xerces project team is pleased to announce that version 2.11.0 of Apache Xerces-J is now available.

This release expands on Xerces' experimental support for XML Schema 1.1 (see Xerces-J-bin.2.11.0-xml-schema-1.1-beta.zip) by providing implementations for the simplified complex type restriction rules (also known as subsumption), xs:override and a few other XML Schema 1.1 features. Xerces-J 2.11.0 also introduces experimental support for XML Schema Component Designators (SCD). It fixes several bugs which were present in Xerces-J 2.10.0 and also includes a few other minor enhancements.
Specifically, the changes introduced in this release are:
  • Implemented XML Schema 1.1's simplified complex type restriction rules (also known as subsumption)
  • Added support for XML Schema 1.1's overriding component definitions (<xs:override>)
  • Added experimental support for a parser and evaluator for XML Schema Component Designators (SCD)
  • Implemented support for the vc:typeAvailable, vc:typeUnavailable, vc:facetAvailable and vc:facetUnavailable attributes for conditional inclusion processing in XML Schema 1.1 documents
  • Implemented support for allowing xs:group as a child of xs:all in XML Schema 1.1 documents
  • Made several enhancements to the support for assertions in the XML Schema 1.1 implementation
  • Improved the ways in which the XML Schema API exposes values and identity constraint information
  • Fixed a bug where XMLSchemaValidator.findSchemaGrammar() was not getting called for substitution groups
  • Fixed a bug in the regular expression support which was introduced in the previous release. See JIRA Issue XERCESJ-1456 for details
  • Fixed multiple issues with decimal precision in the processing of xs:precisionDecimal value
  • Fixed various bugs and made various improvements
