Release Notes for X11R6.8.2 the X.Orgfoundation the Xfree86 Project, Inc
Release Notes for X11R6.8.2 The X.OrgFoundation The XFree86 Project, Inc. 9February 2005 Abstract These release notes contains information about features and their status in the X.Org Foundation X11R6.8.2 release. It is based on the XFree86 4.4RC2 RELNOTES docu- ment published by The XFree86™ Project, Inc. Thereare significant updates and dif- ferences in the X.Orgrelease as noted below. 1. Introduction to the X11R6.8.2 Release The release numbering is based on the original MIT X numbering system. X11refers to the ver- sion of the network protocol that the X Window system is based on: Version 11was first released in 1988 and has been stable for 15 years, with only upwardcompatible additions to the coreX protocol, a recordofstability envied in computing. Formal releases of X started with X version 9 from MIT;the first commercial X products werebased on X version 10. The MIT X Consortium and its successors, the X Consortium, the Open Group X Project Team, and the X.OrgGroup released versions X11R3 through X11R6.6, beforethe founding of the X.OrgFoundation. Therewill be futuremaintenance releases in the X11R6.8.x series. However,efforts arewell underway to split the X distribution into its modular components to allow for easier maintenance and independent updates. We expect a transitional period while both X11R6.8 releases arebeing fielded and the modular release completed and deployed while both will be available as different consumers of X technology have different constraints on deployment. Wehave not yet decided how the modular X releases will be numbered. We encourage you to submit bug fixes and enhancements to bugzilla.freedesktop.orgusing the xorgproduct, and discussions on this server take place on <[email protected]>. -

Trabajo Practico De Teoría De Aplicación a La Informática 2
Trabajo Practico de Teoría de Aplicación a la Informática 2 XGL: aceleración OpenGL para el escritorio del sistema operativo Linux Nicolás González Oddone Universidad Católica Nuestra Señora de la Asunción 20 de setiembre de 2006 Breve historia del Xgl Xgl es concebido para proveer un servidor X basado en GL para escribir en el stack GL, proveyendo asi de un contexto OpenGL para que algun cliente OpenGL pueda hacer uso de este contexto y realize funciones de compisiting. Xgl fue desarrollado originalmente a través de listas de mail publicas, pero por un largo tiempo y hasta hasta el 2 de enero del 2006 la mayoría del desarrollo de Xgl se realizo a puertas cerradas por el equipo de desarrollo de escritorio de Novell. Ese 2 de enero el código volvió a liberarse al publico y fue incluido en freedesktop.org, junto con una reestructuración mayor para soporte mas amplio de drivers de display. En febrero del 2006 el servidor gano publicidad al ser exhibido por equipo de escritorio de Novell en una manera similar a la que se podrá apreciar en breve. Antes que nada es importante familiarizarse con algunos términos que serán necesarios para entender el funcionamiento del XGL y la comunicación del mismo con los servidores de ventanas del escritorio y los protocolos de comunicación utilizados. Comunicación entre el Xorg, Xgl y el cliente OpenGL, a través de libGL y el protocolo GLX Las aplicaciones X11 se comunican con el servidor utilizando libX11, una aplicación OpenGL se comunica con las extensiones GLX y al driver 3D utilizando libGL. -

Optimization of Fontconfig Library Optimization of Fontconfig Library
Michal Srb OPTIMIZATION OF FONTCONFIG LIBRARY OPTIMIZATION OF FONTCONFIG LIBRARY Michal Srb Bachelor's Thesis Spring 2017 Information Technology Oulu University of Applied Sciences ABSTRACT Oulu University of Applied Sciences Degree Programme in Information Technology, Internet Services Author: Michal Srb Title of the bachelor’s thesis: Optimization of Fontconfig Library Supervisor: Teemu Korpela Term and year of completion: Spring 2017 Number of pages: 39 + 1 appendix Fontconfig is a library that manages a database of fonts on Linux systems. The aim of this Bachelor's thesis was to explore options for making it respond faster to application's queries. The library was identified as a bottleneck during the startup of graphical applications. The typical usage of the library by applications was analyzed and a set of standalone benchmarks were created. The library was profiled to identify hot spots and multiple optimizations were applied to it. It was determined that to achieve an optimal performance, a complete rewrite would be necessary. However, that could not be done while staying backward compatible. Nevertheless, the optimizations applied to the existing fontconfig yielded significant performance improvements, up to 98% speedups in benchmarks based on the real-world usage. Keywords: fontconfig, optimization, benchmarking, profiling 3 CONTENTS 1 INTRODUCTION 6 2 BACKGROUND 7 1.1 Motivation 7 1.2 Fontconfig 8 1.2.1 Function 9 1.2.2 Configuration 11 2 ANALYSIS 12 2.1 Main entry functions 12 2.1.1 FcFontMatch 12 2.1.2 FcFontSort 14 2.1.3 -
Insider Threat Detection with Text Libraries and Machine Learning
Insider Threat Detection with Text Libraries and Machine Learning A Major Qualifying Project Submitted to the Faculty of Worcester Polytechnic Institute In partial fulfillment of the requirement for the Degree in Bachelor of Science in Computer Science By Bryan Z. Li Patrick R. Kane Date: 12/19/2013 Project Advisor: Prof. Craig Shue, Advisor This report represents work of WPI undergraduate students submitted to the faculty as evidence of a degree requirement. WPI routinely publishes these reports on its web site without editorial or peer review. For more information about the projects program at WPI, see http://www.wpi.edu/Academics/Projects 1 Abstract Company networks are protected by firewalls and other measures to ensure that data remains secure. However, these same companies have limited techniques to protect information from being compromised from inside the closed network. According to CERT, the Computer Emergency Readiness Team, over 700 unique cases are currently documented and growing rapidly [20]. Sensitive company documents are leaked every year by means of email, printed documents, USB flash drives, and other mediums of data storage. Because there are many legitimate reasons for accessing secret data, insider threats are extremely difficult to detect. A company cannot simply create a policy that bans the use of USB drives or printing, because there are many instances where an employee would be required to print or transfer files using a USB flash drive. In addition to the difficulty of detecting insider threats, the consequences of such attacks can be catastrophic, as is the case with the whistleblower Edward Snowden and his release of documents pertaining to the NSA. -

Release Notes for Xfree86® 4.8.0 the Xfree86 Project, Inc December 2008
Release Notes for XFree86® 4.8.0 The XFree86 Project, Inc December 2008 Abstract This document contains information about the various features and their current sta- tus in the XFree86 4.8.0 release. 1. Introduction to the 4.x Release Series XFree86 4.0 was the first official release of the XFree86 4 series. The current release (4.8.0) is the latest in that series. The XFree86 4.x series represents a significant redesign of the XFree86 X server,with a strong focus on modularity and configurability. 2. Configuration: aQuickSynopsis Automatic configuration was introduced with XFree86 4.4.0 which makes it possible to start XFree86 without first creating a configuration file. This has been further improved in subsequent releases. If you experienced any problems with automatic configuration in a previous release, it is worth trying it again with this release. While the initial automatic configuration support was originally targeted just for Linux and the FreeBSD variants, as of 4.5.0 it also includes Solaris, NetBSD and OpenBSD support. Full support for automatic configuration is planned for other platforms in futurereleases. If you arerunning Linux, FreeBSD, NetBSD, OpenBSD, or Solaris, try Auto Configuration by run- ning: XFree86 -autoconfig If you want to customise some things afterwards, you can cut and paste the automatically gener- ated configuration from the /var/log/XFree86.0.log file into an XF86Config file and make your customisations there. If you need to customise some parts of the configuration while leav- ing others to be automatically detected, you can combine a partial static configuration with the automatically detected one by running: XFree86 -appendauto If you areusing a platform that is not currently supported, then you must try one of the older methods for getting started like "xf86cfg", which is our graphical configuration tool. -
