    Designing and Packaging Printer and Scanner Drivers OpenPrinting MC on Linux Plumbers 2020 August 28, 2020 Till Kamppeter, OpenPrinting What we had ● Printer drivers – PPD files – Filters, perhaps also backends – All has to be in CUPS-specific directories ● Scanner drivers – Shared libraries with SANE ABI in SANE-specific directories ● Packaging – Binaries were built specific to destination distro and packaged in DEB or RPM packages – For each distro drivers need to be built, packaged, and tested separately – As files need to be in specific directories drivers cannot be installed with CUPS in a Snap or with scanning user applications in Snaps What we want ● Sandboxed packaging – Snaps – Distribution-independent: Install from Snap Store on any distro running snapd – More security: Every package with all its libraries and files in its own sandbox, fine-grained control for communication between packages – All-Snap distributions ● But – You cannot drop driver files into directories of a snapped CUPS or snapped user applications, Snaps do not see the system’s files – Snaps only communicate via IP or D-Bus, not by files ● Also – CUPS is deprecating support for PPD files, working by itself only in driverless IPP mode. The New Architecture ● Printer/Scanner Applications emulating an IPP device – Easily snappable: Communicates only via IP – Multi-function device support, Printing, Scanning, and Fax Out can be done in one Snap/Application – Web admin interface for vendor/device-specific GUI – Behaves like a network printer/scanner/multi-function

  • Rkward: a Comprehensive Graphical User Interface and Integrated Development Environment for Statistical Analysis with R
    JSS Journal of Statistical Software June 2012, Volume 49, Issue 9. http://www.jstatsoft.org/ RKWard: A Comprehensive Graphical User Interface and Integrated Development Environment for Statistical Analysis with R Stefan R¨odiger Thomas Friedrichsmeier Charit´e-Universit¨atsmedizin Berlin Ruhr-University Bochum Prasenjit Kapat Meik Michalke The Ohio State University Heinrich Heine University Dusseldorf¨ Abstract R is a free open-source implementation of the S statistical computing language and programming environment. The current status of R is a command line driven interface with no advanced cross-platform graphical user interface (GUI), but it includes tools for building such. Over the past years, proprietary and non-proprietary GUI solutions have emerged, based on internal or external tool kits, with different scopes and technological concepts. For example, Rgui.exe and Rgui.app have become the de facto GUI on the Microsoft Windows and Mac OS X platforms, respectively, for most users. In this paper we discuss RKWard which aims to be both a comprehensive GUI and an integrated devel- opment environment for R. RKWard is based on the KDE software libraries. Statistical procedures and plots are implemented using an extendable plugin architecture based on ECMAScript (JavaScript), R, and XML. RKWard provides an excellent tool to manage different types of data objects; even allowing for seamless editing of certain types. The objective of RKWard is to provide a portable and extensible R interface for both basic and advanced statistical and graphical analysis, while not compromising on flexibility and modularity of the R programming environment itself. Keywords: GUI, integrated development environment, plugin, R.
