  • A Multiplatform Pseudo Terminal
    A Multi-Platform Pseudo Terminal API Project Report Submitted in Partial Fulfillment for the Masters' Degree in Computer Science By Qutaiba Mahmoud Supervised By Dr. Clinton Jeffery ABSTRACT This project is the construction of a pseudo-terminal API, which will provide a pseudo-terminal interface access to interactive programs. The API is aimed at developing an extension to the Unicon language to allow Unicon programs to easily utilize applications that require user interaction via a terminal. A pseudo-terminal is a pair of virtual devices that provide a bidirectional communication channel. This project was constructed to enable an enhancement to a collaborative virtual environment, because it will allow external tools such to be utilized within the same environment. In general the purpose of this API is to allow the UNICON runtime system to act as the user via the terminal which is provided by the API, the terminal is in turn connected to a client process such as a compiler, debugger, or an editor. It can also be viewed as a way for the UNICON environment to control and customize the input and output of external programs. Table of Contents: 1. Introduction 1.1 Pseudo Terminals 1.2 Other Terminals 1.3 Relation To Other Pseudo Terminal Applications. 2. Methodology 2.1 Pseudo Terminal API Function Description 3. Results 3.1 UNIX Implementation 3.2 Windows Implementation 4. Conclusion 5. Recommendations 6. References Acknowledgments I would like to thank my advisor, Dr. Clinton Jeffery, for his support, patience and understanding. Dr. Jeffery has always been prompt in delivering and sharing his knowledge and in providing his assistance.

  • An Empirical Investigation Into Programming Language Syntax
    i i i i An Empirical Investigation into Programming Language Syntax ANDREAS STEFIK, University of Nevada, Las Vegas SUSANNA SIEBERT, The Genome Institute, Washington University School of Medicine Recent studies in the literature have shown that syntax remains a significant barrier to novice computer science students in the field. While this syntax barrier is known to exist, whether and how it varies across programming languages has not been carefully investigated. For this article, we conducted four empirical studies on programming language syntax as part of a larger analysis into the, so called, programming language wars. We first present two surveys conducted with students on the intuitiveness of syntax, which we used to garner formative clues on what words and symbols might be easy for novices to understand. We followed up with two studies on the accuracy rates of novices using a total of six programming languages: Ruby, Java, Perl, Python, Randomo, and Quorum. Randomo was designed by randomly choosing some keywords from the ASCII table (a metaphorical placebo). To our surprise, we found that languages using a more traditional C-style syntax (both Perl and Java) did not afford accuracy rates significantly higher than a language with randomly generated keywords, but that languages which deviate (Quorum, Python, and Ruby) did. These results, including the specifics of syntax that are particularly problematic for novices, may help teachers of introductory programming courses in choosing appropriate first languages and in helping students to overcome the challenges they face with syntax. Categories and Subject Descriptors: D.3 [Programming Languages]; H.1.2 [Information Systems]: User/Machine Systems—Software psychology General Terms: Design, Experimentation, Human Factors, Standardization Additional Key Words and Phrases: Programming Languages, Novice Programmers, Syntax ACM Reference Format: Stefik, A.

  • Cucumber Linux Distribution Scott Court February 16, 2018 Who Am I?
    An Overview of How I Created the Cucumber Linux Distribution Scott Court February 16, 2018 Who am I? What is Cucumber Linux? ● A Linux distribution built entirely from source, from scratch ● An independent distribution: it’s not based on any other Linux distribution. ● Inspired by: a mixture of Slackware and Linux from Scratch. ● Architectures: i686 and x86_64 ● Package manager: pkgtools (borrowed from Slackware; uses tar archives as packages like Pacman). ● License: MIT ● Mission: provide a Linux distribution that follows the Unix Philosophy with a focus on simplicity, stability and security, and is usable as an every day, general purpose operating system. What can it Do? ● It’s functional as both a server and desktop operating system. ● Server Operating System: – Contains a fully functional LAMP stack as well as SSH, mail, DNS, FTP and Rsync servers. – Runs the web server and mail server for cucumberlinux.com. – Runs the primary mirror for Cucumber Linux (http and rsync). ● Desktop Operating System: – Comes with the XFCE desktop environment, a web browser, a mail client and an office suite. – It’s running this presentation right now. May 2016 – How it Began ● I had just completed my freshman year of college. ● I was looking for a project to work on that Summer. ● I had grown unhappy with the direction most every other Linux distribution was going in (namely the exodus from Sysvinit to Systemd). ● I had always had an interest in operating system development. ● So I set out to make my own Linux distribution, without Systemd. May 2016 – July 2016 ● May, June and July of 2016 were spent doing research and trying out different techniques for building a Linux system from scratch.
