Mitterdorfer Proceedings of I-MEDIA ’07 and I-SEMANTICS ’07 Graz, Austria, September 5-7, 2007 I-MEDIA ’07 and I-SEMANTICS ’07 International Conferences on New Media Technology and Semantic Systems Preface This volume contains the proceedings of I-MEDIA ’07 and I-SEMANTICS ’07, which are part of the TRIPLE-I conference series. TRIPLE-I reflects the increasing importance and convergence of knowledge management, new media technologies and semantic systems. I-MEDIA ’07 addresses the latest scientific achievements in new media technologies. The contributions published in these proceedings range from success factors for user generated content to interactive TV services to semantic multi-media tagging. I-SEMANTICS ’07 addresses latest scientific results in semantic systems and complements these topics with brand new research challenges in the area of social software, semantic content engineering, logic programming and Semantic Web technologies. Both conferences welcome leading researchers and practitioners who present their ideas to more than 500 TRIPLE-I attendees. An international program committee selected 50 full papers and six short papers to be included in the conference proceedings. In addition to a high-quality program, networking is considered an important element of the conference. Community building is fostered in special interactive events designed around particular themes. Deliberately long breaks throughout the conference and social events in the evenings provide excellent opportunities for meeting people from all over the world. The program of I-MEDIA ’07 and I-SEMANTICS ’07 is structured as follows. In thematically focused events, community building is supported. Experts and an interested audience are brought together for an in-depth discourse in focused thematic areas. Two special tracks on Semantics in Life Science and Reasoning and Deduction Systems as well as a workshop on Multimedia Metadata Applications are examples for such events. These special events are complemented by presentations covering current trends and latest developments in new media technologies and semantic systems. The presentations include but are not limited to the following areas: - Semantic Desktop - Semantic Social Software - Semantic Modeling - Media Convergence - Media Semantics - Social Networks Events such as the I-MEDIA ’07 and I-SEMANTICS ’07 require active support at different levels: We are grateful to our three invited keynote speakers, Martin 2 K.

We consider systems having reduction semantics; i.e., systems in which computations consist of equivalence-preserving transformations between expressions. The approach becomes possible by reducing expressions beyond weak normal form, allowing expression-level output values, and avoiding compilation-centered transformations. In particular, we develop reduction algorithms which, although not optimal, are highly efficient. A minimal linear notation for lambda expressions and for certain runtime structures is introduced for explaining operational features. This notation is related to recent theories which formalize the notion of substitution. Our main reduction technique is Berkling’s Head Order Reduction (HOR), a delayed substitution algorithm which emphasizes the extended left spine. HOR uses the de Bruijn representation for variables and a mechanism for artificially binding relatively free variables. HOR produces a lazy variant of the head normal form, the natural midway point of reduction. It is shown that beta reduction in the scope of relative free variables is not hard.

Contributor the vast majority of you probably know me (or have at least seen me H around the forums), I feel that I should take a moment to introduce myself. My name is Daniel Griffiths, and I am a 26-year-old independent contractor in Delaware, US. Throughout my life, I have wandered through various UNIX/Linux systems including (but not limited to) MINIX, RedHat, Mandrake, Slackware, Gentoo, Debian, and even two home made distributions based on Linux From Scratch. I finally found Arch in 2007 and instantly fell in love with its elegant simplicity. Some of our more attentive readers may note that Arch already has a monthly newsletter. With the existence of the aformentioned newsletter, what is the point of adding another news medium to the mix? Fear not, newsletter readers, I have no intention of letting Arch User Magazine take the place of the newsletter. In fact, Arch User Magazine and the newsletter are intended to fill two very different needs in the Arch community.

First released in 1971 and was written in assembler. In 1973, Unix was re-written in the programming language C by Dennis Ritchie (with exceptions to the kernel and I/O). The availability of an operating system written in a high-level language allowed easier portability to di↵erent computer platforms. The GNU Project, started in 1983 by Richard Stallman, had the goal of creating a “complete Unix-compatible software system” composed entirely of free software. 386BSD released in 1992 and written by Berkeley alumni Lynne Jolitz and William Jolitz.

Because of this, there is a lot of customization and tweaking involved to get a working environment you are completely happy with. This may seem like a downside. However, consider the control one now has over their desktop environment – the sky’s the limit.

    Preliminary Report: Xmonad Practical Course – Contributing to an Open-Source Project Chair for Chair for Logic and Verification Technical University of Munich

    Preliminary Report: XMonad Practical Course – Contributing to an Open-Source Project Chair for Chair for Logic and Verification Technical University of Munich Yecine Megdiche 1st of December 2020 1 Introduction and definitions XMonad is a “dynamically tiling X11 window manager that is written and configured in Haskell”. It is designed to be “lightweight, minimal, extremely customizable and crash-free”. This window manager is entirely usable with just the keyboard, with optional mouse support [1]. It is considered as one of the well known “real-world” software written in Haskell1. 1.1 Definitions • X11 Window System: The most used GUIs manager on UNIX-Like Operating Systems [2]. • Window Manager: The ArchWiki [3] defines a window manager as a “system software that controls the placement and appearance of windows within a windowing system in a graphical user interface.” – Tiling Window managers: Window managers who place win- dows in non-overlapping tiles are called tiling window managers, in contrast to stacking or floating window managers. [3] 1https://github.com/xmonad/xmonad/issues/93#issuecomment-298145660 1 2 XMonad: Short History and Motivation Spencer Janssen, one of the original authors of XMonad, used dwm2 as his window manager. Dwm is a tiling window manager, written and configured in C. That inspired him to create a similar project in Haskell, which he, Don Stewart, and Jason Creighton worked on. Brandon S. Allbery helped them make XMonad compliant with the “Inter-Client Communication Conventions Manual” rules defined by X11.[4] XMonad was announced on the 22nd of April 2007 by Spencer Janssen over at the Haskell-café mailing-list [5].

Prof. Dr. Ren´eThiemann (Universit¨atInnsbruck) This work has been partially supported by the research grants FPI-UR-12, ATUR13/25, ATUR14/09, ATUR15/09 from Universidad de La Rioja, and by the project MTM2014-54151-P from Ministerio de Econom´ıay Competitividad (Gobierno de Espa~na). Abstract This thesis studies the formalisation and execution of Linear Algebra algorithms in Isabelle/HOL, an interactive theorem prover. The work is based on the HOL Multivariate Analysis library, whose matrix representation has been refined to datatypes that admit a representation in functional programming languages. This enables the generation of programs from such verified algorithms. In par- ticular, several well-known Linear Algebra algorithms have been formalised in- volving both the computation of matrix canonical forms and decompositions (such as the Gauss-Jordan algorithm, echelon form, Hermite normal form, and QR decomposition). The formalisation of these algorithms is also accompanied by the formal proofs of their particular applications such as calculation of the rank of a matrix, solution of systems of linear equations, orthogonal matrices, least squares approximations of systems of linear equations, and computation of determinants of matrices over B´ezoutdomains.
