Tesis Para Imprimir Hacer Cambios Pontificia Universidad Católica del Ecuador Facultad de Ingeniería Escuela de Sistemas GUIA DE MIGRACIÓN DE ESTACIONES DE TRABAJO BASADAS EN SOFTWARE PROPIETARIO A ESTACIONES DE TRABAJO BASADAS EN SOFTWARE DE LIBRE DISTRIBUCIÓN. POR: Pedro Antonio Barzallo Enríquez. Quito, 2010 DEDICATORIA A Eliza Beltrán Torres, mi querida abuelita quien con todo su corazón me alentó y me ayudó a culminar la carrera a mi esposa e hijos que me han apoyado a mi padre quien ha estado pendiente todo este tiempo. EXTRACTO DE LA TESIS GUIA DE MIGRACIÓN DE ESTACIONES DE TRABAJO BASADAS EN SOFTWARE PROPIETARIO A ESTACIONES DE TRABAJO BASADAS EN SOFTWARE DE LIBRE DISTRIBUCIÓN En la actualidad la informática y la automatización de procesos a través de software ha tomado una importancia sin precedentes, tanto a nivel local como nacional e internacional. La informática, en todos los procesos que interviene, bien organizada, administrada y utilizada permite que las organizaciones logren alcanzar sus metas en los tiempos previstos, manteniendo también los presupuestos económicos dentro de niveles aceptables. Sin embargo, poco a poco, la posibilidad de acceder a software de buena calidad de manera legal sin que esto represente un alto grado de inversión se ha vuelto una verdadera pesadilla con la que más de un ingeniero de sistemas ha tenido que luchar. Este escenario se puede observar sobre todo en las pequeñas y medianas organizaciones de nuestro medio, que no están dispuestas a invertir altos porcentajes de su presupuesto en la adquisición de las respectivas licencias de software comercial o propietario. Muchos procesos de automatización y procesamiento de información que se realizan en nuestro medio se realizan con software que generalmente es de dudosa procedencia o que no han sido legalmente adquiridos. El poco conocimiento y uso a nivel local ya sea en pymes o gobierno de las posibilidades reales de trabajar eficientemente con software basado en GNU o de libre distribución hace que estas organizaciones sean poco competitivas y no logren por lo general alcanzar sus metas sin que de por medio exista una fuerte inversión en licenciamiento de software comercial o en su defecto de que se vulnere la ley. Existe una alternativa real basada en SOFTWARE DE LIBRE DISTRIBUCIÓN, en estos últimos años el software libre ha ganado terreno en su uso a nivel de instalación de servidores, sobre todo de comunicaciones (correo electrónico, Web Hosting, DNS, Base de datos, entre otros). Sin embargo la plataforma no ha logrado el mismo éxito en su uso como estación de trabajo o cliente, a pesar de que han existido interesantes cambios en la estructura de las aplicaciones para cliente final, su facilidad de uso y su alto nivel de distribución a través del internet y otros medios, aplicaciones como OpenOffice 3.1, Guimp, Firefox, Thunderbird, Ximian Evolution, Horde, entre otras, las cuales pueden ser instaladas bajo MS Windows o cualquier distribución de Linux. Es posible cambiar el paradigma de uso del software comercial como única solución a los problemas de tratamiento de información en las pymes, utilizando para esto la migración a software de libre de libre distribución mostrando la posibilidad de ahorrar dinero ya sea cambiando completamente de plataforma de sistema operativo o únicamente utilizando herramientas sujetas a licenciamiento del software de libre distribución sin perder desempeño. A través del presente documento se espera brindar una herramienta efectiva, para la migración desde plataformas de software de pago o privado, a herramientas de software libre. Índice 1.

AN INFRASTRUCTURE TO SUPPORT INTEROPERABILITY IN REVERSE ENGINEERING A Dissertation Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Computer Science by Nicholas A. Kraft May 2007 Accepted by: Dr. Brian A. Malloy, Committee Chair Dr. Harold C. Grossman Dr. James F. Power Dr. Roy P. Pargas ABSTRACT An infrastructure that supports interoperability among reverse engineering tools and other software tools is described. The three major components of the infrastruc- ture are: (1) a hierarchy of schemas for low- and middle-level program representation graphs, (2) g4re, a tool chain for reverse engineering C++ programs, and (3) a repos- itory of reverse engineering artifacts, including the previous two components, a test suite, and tools, GXL instances, and XSLT transformations for graphs at each level of the hierarchy. The results of two case studies that investigated the space and time costs incurred by the infrastructure are provided. The results of two empirical evaluations that were performed using the api module of g4re, and were focused on computation of object-oriented metrics and three-dimensional visualization of class template diagrams, respectively, are also provided.

  • A Semantic Description Language for Platform-Independent Graphical User Interfaces
    Studiengang: Informatik Prüfer: Prof. Dr. T. Ertl Betreuer: Dipl. Inf. Simon Stegmaier begonnen am: 16. Mai 2002 beendet am: 22. November 2002 CR-Klassifikation: H.5.2, I.3.6, C.2.4 Diplomarbeit Nr. 2017 A Semantic Description Language for Platform-Independent Graphical User Interfaces Christoph Pfisterer Institut für Visualisierung und Interaktive Systeme Universität Stuttgart Breitwiesenstraße 20–22 D–70565 Stuttgart Abstract Graphical user interface toolkits exhibit striking similarities in functionality and vi- sual appearance. Yet, each one demands adherence to its proprietary implementation interface from the application developer. Platform-independent solutions exist, but their perceived drawbacks hinder large-scale adaption. This thesis provides a new perspective by complementing platform abstraction with other benefits found in some toolkits today. Network transparency and programming language abstraction are gained through the use of a remote protocol. An XML-based description language reduces coding effort and enables interactive dialog editors. The language is taken to a higher level by including elements to denote the behavior of the interface in addition to its structure. Existing solutions are examined to provide an overview of useful features, but also to learn about shortcomings. Based on this examination, the architecture of the new system is then designed. The viability of the approach is demonstrated by a prototype implementation. It is based on the Qt toolkit and BEEP, a network protocol framework. Deutsche Zusammenfassung Verschiedene Toolkits zur Erstellung von grafischen Benutzungsoberflächen weisen erstaunliche visuelle Ähnlichkeiten auf. Dennoch hat jedes Toolkit eine eigene Pro- grammierschnittstelle, die der Programmierer verwenden muss. Plattformunabhän- gige Lösungen wurden entwickelt, werden aber wegen befürchteter Nachteile nur schleppend angenommen.

  • Herman Skolnik Award Symposium Honoring Henry Rzepa and Peter Murray-Rust ACS National Meeting, Philadelphia, PA, August 21, 2012
    Herman Skolnik Award Symposium Honoring Henry Rzepa and Peter Murray-Rust ACS National Meeting, Philadelphia, PA, August 21, 2012 A report by Wendy Warr ([email protected]) for the ACS CINF Chemical Information Bulletin Introduction This one-day symposium was remarkable for its record number of speakers (23 in all, plus one withdrawn and one replaced by a demonstration). Despite the number of performers, and some unfortunate technical faults, the whole event proceeded on schedule and without serious mishap. Henry Rzepa’s own talk was an opening scene-setter. He told a 1992 tale of some molecular orbitals explaining the course of a chemical reaction in 1992. The color diagram of these lacked semantics, and when it had been sent by fax to Bangor, it even lost its color. Months later the work was published,1 but the supporting information (SI) is not available for this article, and even if it were available electronically, would it be usable? So, how can it be mined for useful data or used as the starting point for further investigation? By 1994 Henry and his colleagues had recognized the opportunities presented by the World Wide Web.2,3 The data for a later article4 do survive in the form of Quicktime and MPEG animations on the Imperial College Gopher+ server but they are semantically poor, i.e., they are interpretable by humans but not by computer. The X-ray crystallography data are locatable using the proprietary identifier HEHXIB allocated by the Cambridge Crystallographic Data Center. Open identifiers such as the IUPAC International Chemical Identifier, InChI, are preferable.

  • Dynamically Registering C++ Exception Handlers: Centralized Handling of C++ Exceptions in Application Framework Libraries
    Dynamically Registering C++ Exception Handlers: Centralized Handling of C++ Exceptions in Application Framework Libraries by Nathaniel H. Daly A thesis submitted in partial fulfillment of the requirements for the degree of Bachelor of Science (Honors Computer Science) in the University of Michigan 2013 Thesis Committee: Professor David Kieras, Advisor Professor David Paoletti, Second Reader Abstract The C++ exceptions mechanism enables modularized programs to separate the reporting of exceptional conditions from the handling of those exceptional condi- tions into the locations where those actions can best be performed. It is often the case in such modular applications that the module capable of detecting an excep- tional situation cannot know how it should be handled, and so C++ exceptions allow the module that invoked the operation to react to the condition. Libraries developed separately from the applications using them are a perfect example of modularized code, and thus a perfect candidate for using C++ exceptions, how- ever many of the application framework library paradigms that have become commonplace do not provide adequate exception support to allow for good pro- gramming style with regard to catching and handling exceptions. In these librar- ies, there often exist multiple callback-style entry points that invoke application- specific operations, all of which require exactly identical exception handling, yet there is no way to collect this code together. Instead, the exception handling code must be duplicated across each entry point. In this paper, I will explore the best solutions to this problem currently provided by such frameworks; I will propose an additional solution to this problem: a method for allowing a program to regis- ter exception-handler operations templated by exception type; and finally, I will identify any impacts that the newly released C++11 standard and the currently evolving C++14 standard have on the problem.
