Active Server Pages (ASP)
Active Server Pages (ASP) Outline 11.1 Introduction 11.2 How Active Server Pages Work 11.3 Client-side Scripting versus Server-side Scripting 11.4 Using Personal Web Server or Internet Information Server 11.5 A Simple ASP Example 11.6 Server-side ActiveX Components 11.7 File System Objects 11.8 Session Tracking and Cookies 11.9 Accessing a Database from an Active Server Page 11.10 Case Study: A Product Catalog 11.1 Introduction • Active Server Pages (ASP) – Processed in response to client request – ASP file contains HTML and scripting code – VBScript de facto language for ASP scripting • Other languages can be used – JavaScript – .asp file extension – Microsoft-developed technology – Send dynamic Web content • HTML • DHTML • ActiveX controls • Client-side scripts • Java applets 11.2 How Active Server Pages Work • Client sends request – Server receives request and directs it to ASP – ASP processes, then returns result to client • HTTP request types – Request methods • GET – Gets (retrieves) information from server – Retrieve HTML document or image • POST – Posts (sends) data to server – Send info from HTML form » Client-entered data » Info to search Internet » Query for a database » Authentication info 11.2 How Active Server Pages Work (II) • Browsers often cache Web pages – Cache: save on disk – Typically do not cache POST response • Next POST request may not return same result • Client requests ASP file – Parsed (top to bottom) by ActiveX component asp.dll • ActiveX component: server-side ActiveX control that usually does not have GUI -
De Geschiedenis Van Linux Hans Lunsing
De geschiedenis van Linux Hans Lunsing Linus Torvalds begon in 1991 met de ontwikkeling van Linux als vervanger van het voor hem veel te dure Unix, dat hem wel als voorbeeld diende. De naam Linux is dan ook een samentrekking van zijn naam Linus en Unix. Daarom kan de vroege geschiedenis van Unix worden gezien als de voorgeschiedenis van Linux. Voorgeschiedenis: Multics voor dat type. Om Unix overdraagbaar te maken werd het zoveel mogelijk herschreven in C.

Report on the 2020 FOSS Contributor Survey
Report on the 2020 FOSS Contributor Survey The Linux Foundation & The Laboratory for Innovation Science at Harvard Frank Nagle Harvard Business School David A. Wheeler The Linux Foundation Hila Lifshitz-Assaf New York University Haylee Ham Jennifer L. Hoffman Laboratory for Innovation Science at Harvard Acknowledgments This report and the research behind it would not have been possible without the leadership of the Core Infrastructure Initiative’s Advisory Committee, composed of Josh Corman, Steve Lipner, Audris Mockus, Henning Piezunka, and Sam Ransbotham. Frank Nagle would also like to thank his fellow co-directors of the Core Infrastructure Initiative, Jim Zemlin at the Linux Foundation and Karim Lakhani at the Laboratory for Innovation Science at Harvard, for their counsel and direction throughout this project. Gratitude and thanks to Michael Dolan and Kate Stewart at the Linux Foundation for their ongoing commitment to this undertaking. Thank you to James Dana for laying the initial groundwork for this survey. Finally — and perhaps, most importantly — thank you to all the individuals who contribute to FOSS projects. Without their tireless efforts, our core digital infrastructure and the feats enabled by it would not be sustainable.

Implementing OGC Web Map Service Client Applications Using JSP, JSTL and XMLC
Implementing OGC Web Map Service Client Applications Using JSP, JSTL and XMLC Hao Ding , Richard Pascoe & Neville Churcher Department of Computer Science University of Canterbury. Christchurch, New Zealand Phone: +64 3 364-2362 Fax: +64 3 364-2569 Email: [email protected] , {richard, neville}@cosc.canterbury.ac.nz Presented at SIRC 2002 – The 14th Annual Colloquium of the Spatial Information Research Centre University of Otago, Dunedin, New Zealand th December 3-5 2002 ABSTRACT Java technologies are widely used in web application development. In this paper are described three approaches to developing Java-based web applications and our experiences with applying each to the development of client that interact with servers implementing the OGC (Open GIS Consortium) Web Map Service (WMS) specification. Also described is the installation and configuration of open source software that implements the WMS specification. The paper is concluded with some preliminary insights into when one of the three approaches to WMS client implementation is more suited to another. Keywords and phrases: WMS, JSP, JSTL, XMLC, map layer, web map server 1.0 INTRODUCTION Of the many technologies, such as Common Gateway Interface (CGI), Active Server Pages (ASP), JavaServer Pages (JSP), that are used to develop web applications, three are of particular interest to the research presented here. These three technologies or approaches to developing clients that utilise web services are JavaServer Pages (JSP), JSP with the use of tags from the JSP Standard Tag Library (JSTL), and the eXtensible Markup Language Compiler (XMLC). JSP is a more convenient way to write Java servlets, and allows the insertion of Java code directly into static HTML (Hypertext Markup Language) pages. -

Tool Support for Computer Role-Playing Game Programming: Foundations, Guidelines and Applications
Tampereen teknillinen yliopisto. Julkaisu 1237 Tampere University of Technology. Publication 1237 Juha-Matti Vanhatupa Tool Support for Computer Role-Playing Game Programming: Foundations, Guidelines and Applications Thesis for the degree of Doctor of Science in Technology to be presented with due permission for public examination and criticism in Tietotalo Building, Auditorium TB222, at Tampere University of Technology, on the 17th of October 2014, at 12 noon. Tampereen teknillinen yliopisto - Tampere University of Technology Tampere 2014 ISBN 978-952-15-3341-9 (printed) ISBN 978-952-15-3393-8 (PDF) ISSN 1459-2045 Abstract Computer role-playing games (CRPGs) are a genre of computer games, which aim at providing similar player experience than their ancestors, paper-and- pen role-playing games. For a type of digital games, their evolution is already rather long, as the first ones were created in 1980s. Typically CRPGs em- phasize character development and to support this huge fantasy worlds and sophisticated storylines are also present. CRPG development has unique challenges, which derive from these typical features. Content creation is a continuous issue, since huge virtual worlds and long storylines must be filled with content. Personalization is also an important issue, because all fun of creating personalized character is lost if it has no effect into the game. Low starting threshold is important for successful game. It is becoming essential that the player can start playing quickly and she is not required to spent time waiting the installation to be completed. This can be achieved by web-based approach, since web-based games do not require installations. -

Please Don’t Go - Increasing Women’s Participation in Open Source Software Bianca Trinkenreich Northern of Arizona University Flagstaff, AZ, USA [email protected] Abstract—Women represent less than 24% of the software the development of the community with norms and values development industry and suffer from various types of prejudice consistent with their own vision [12], focusing on the first and biases. In Open Source Software projects, despite a variety social experiences through programs such as mentorships [13], of efforts to increase diversity and multi-gendered participation, women are even more underrepresented (less than 10%). My and fixing the gender-bias issues in non-inclusive tools and research focuses on answering the question: How can OSS infrastructure [14]. Some strategies that are discouraged by communities increase women’s participation in OSS projects? the literature include setting quotas for women. Just increasing I will identify the different OSS career pathways, and develop the proportion of women can lead to questioning stereotypes a holistic view of women’s motivations to join or leave OSS, and decisions to simply re-classify types of work that are cur- along with their definitions of success. Based on this empirical investigation, I will work together with the Linux Foundation rently packaged in masculine-feminine stereotyped specialties. to design attraction and retention strategies focused on women. Another discouraged strategy is related to coding schools that Before and after implementing the strategies, I will conduct train women in specialties where they are already represented. empirical studies to evaluate the state of the practice and These schools might perpetuate the disadvantage of women understand the implications of the strategies. -
