Program Library HOWTO David A
Program Library HOWTO David A. Wheeler version 1.36, 15 May 2010 This HOWTO for programmers discusses how to create and use program libraries on Linux. This includes static libraries, shared libraries, and dynamically loaded libraries.

Designing and Packaging Printer and Scanner Drivers
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 -

The motivation for H the research arises from problems detected in the remote 1 4 2 interaction with embedded devices over dynamic wireless networks in such systems. The selected approach is based on the application of the small- world paradigm to cyber-physical systems. It is here assumed that the concept of small world, "six degrees of separation", can be expanded to also cover communication with wireless embedded devices in cyber-physical systems context. The main contributions are the technical enablers referred to as dynamic communication spaces, dynamic M2M service spaces, configuration and remote use of services, communication overlay, access systems selection, integrated mobility, secure ad hoc networking, situated opportunistic communication, hierarchical networking for small-world networks, and short-cuts for network optimization. The enablers have been evaluated as separate technical methods and means by means of experiments and/or simulations. According to the evaluations, the enablers seem to work well as separate building blocks and that they can be combined to expand the concept of small world to also cover communication with embedded devices. Wireless short-cuts can improve the scalability and efficiency of dynamic wireless networking and weak links are essential in the neighbour discovery process. -
Ubuntu Kung Fu
Prepared exclusively for Alison Tyler Download at Boykma.Com What readers are saying about Ubuntu Kung Fu Ubuntu Kung Fu is excellent. The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users. Matthew Helmke Administrator, Ubuntu Forums Ubuntu Kung Fu is a fantastic compendium of useful, uncommon Ubuntu knowledge.

To address this gap in knowledge, we systematically investigate Mutation-based fuzzing typically uses an initial set of valid seed and evaluate how seed selection affects a fuzzer’s ability to find bugs inputs from which to generate new seeds by random mutation. -
