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.

An User & Developer Perspective on Immutable Oses
An User & Developer Perspective on Dario Faggioli Virtualization SW. Eng. @ SUSE Immutable OSes [email protected] dariof @DarioFaggioli https://dariofaggioli.wordpress.com/ https://about.me/dario.faggioli About Me What I do ● Virtualization Specialist Sw. Eng. @ SUSE since 2018, working on Xen, KVM, QEMU, mostly about performance related stuff ● Daily activities ⇒ how and what for I use my workstation ○ Read and send emails (Evolution, git-send-email, stg mail, ...) ○ Write, build & test code (Xen, KVM, Libvirt, QEMU) ○ Work with the Open Build Service (OBS) ○ Browse Web ○ Test OSes in VMs ○ Meetings / Video calls / Online conferences ○ Chat, work and personal ○ Some 3D Printing ○ Occasionally play games ○ Occasional video-editing ○ Maybe scan / print some document 2 ● Can all of the above be done with an immutable OS ? Immutable OS: What ? Either: ● An OS that you cannot modify Or, at least: ● An OS that you will have an hard time modifying What do you mean “modify” ? ● E.g., installing packages ● ⇒ An OS on which you cannot install packages ● ⇒ An OS on which you will have an hard time installing packages 3 Immutable OS: What ? Seriously? 4 Immutable OS: Why ? Because it will stay clean and hard to break ● Does this sound familiar? ○ Let’s install foo, and it’s dependency, libfoobar_1 ○ Let’s install bar (depends from libfoobar_1, we have it already) ○ Actually, let’s add an external repo. It has libfoobar_2 that makes foo work better! ○ Oh no... libfoobar_2 would break bar!! ● Yeah. It happens. Even in the best families distros -

Performance Testing Suricata The Effect of Configuration Variables On Offline Suricata Performance A Project Completed for CS 6266 Under Jonathon T. Giffin, Assistant Professor, Georgia Institute of Technology by Winston H Messer Project Advisor: Matt Jonkman, President, Open Information Security Foundation December 2011 Messer ii Abstract The Suricata IDS/IPS engine, a viable alternative to Snort, has a multitude of potential configurations. A simplified automated testing system was devised for the purpose of performance testing Suricata in an offline environment. Of the available configuration variables, seventeen were analyzed independently by testing in fifty-six configurations. Of these, three variables were found to have a statistically significant effect on performance: Detect Engine Profile, Multi Pattern Algorithm, and CPU affinity. Acknowledgements In writing the final report on this endeavor, I would like to start by thanking four people who made this project possible: Matt Jonkman, President, Open Information Security Foundation: For allowing me the opportunity to carry out this project under his supervision. Victor Julien, Lead Programmer, Open Information Security Foundation and Anne-Fleur Koolstra, Documentation Specialist, Open Information Security Foundation: For their willingness to share their wisdom and experience of Suricata via email for the past four months. John M. Weathersby, Jr., Executive Director, Open Source Software Institute: For allowing me the use of Institute equipment for the creation of a suitable testing -
A Training Programme for Early-Stage Researchers That Focuses on Developing Personal Science Outreach Portfolios
A training programme for early-stage researchers that focuses on developing personal science outreach portfolios Shaeema Zaman Ahmed1, Arthur Hjorth2, Janet Frances Rafner2 , Carrie Ann Weidner1, Gitte Kragh2, Jesper Hasseriis Mohr Jensen1, Julien Bobroff3, Kristian Hvidtfelt Nielsen4, Jacob Friis Sherson*1,2 1 Department of Physics and Astronomy, Aarhus University, Denmark 2 Department of Management, Aarhus University, Denmark 3 Laboratoire de Physique des Solides, Université Paris-Saclay, CNRS, France 4 Centre for Science Studies, Aarhus University, Denmark *[email protected] Abstract Development of outreach skills is critical for researchers when communicating their work to non-expert audiences. However, due to the lack of formal training, researchers are typically unaware of the benefits of outreach training and often under-prioritize outreach. We present a training programme conducted with an international network of PhD students in quantum physics, which focused on developing outreach skills and an understanding of the associated professional benefits by creating an outreach portfolio consisting of a range of implementable outreach products. We describe our approach, assess the impact, and provide guidelines for designing similar programmes across scientific disciplines in the future. Keywords: science outreach, science communication, training, professional development Introduction Recent years have seen an increased call for outreach and science communication training by research agencies such as the National Science Foundation -

Proceedings of ICEM&SIIE‘11 Joint Conference EVTux: uma distribuição de Linux para a integração das ferramentas digitais na disciplina de EVT José Alberto Rodrigues Universidade de Aveiro Portugal [email protected] António Moreira Universidade de Aveiro Portugal [email protected] Resumo O EVTux1 é uma distribuição de Linux que tem por base o trabalho de investigação que desenvolvemos sobre a integração de ferramentas digitais na disciplina de Educação Visual e Tecnológica. Após quinze meses de estudo e desenvolvimento do projeto, recensearam- se quase quatrocentas ferramentas digitais passíveis de integração em contexto de Educação Visual e Tecnológica. O EVTux tem pré instaladas todas as aplicações para Linux bem como integradas no browser as ferramentas digitais que não necessitam de instalação e correm diretamente a partir da Web, para além dos mais de trezentos manuais de apoio à utilização dessas ferramentas. O EVTux está disponível em versão live ou dual boot e constitui-se como um poderoso recurso podendo ser uma ferramenta de eleição para os docentes desta disciplina utilizarem em contexto de sala de aula. Palavras-chave: Currículo; Educação; Educação Visual e Tecnológica; EVTdigital; EVTux. 1. Introdução Decorrente da investigação que atualmente desenvolvemos no âmbito do Programa Doutoral em Multimédia em Educação da Universidade de Aveiro intitulado ―Ferramentas Web, Web 2.0 e Software Livre em EVT‖, foram recenseadas e catalogadas cerca de quatrocentas ferramentas digitais passíveis de utilização em contexto de Educação Visual e Tecnológica (EVT), disciplina do 2º Ciclo do Ensino Básico, para abordagem dos diversos conteúdos e áreas de exploração da mesma, integrados em múltiplas Unidades de Trabalho desenvolvidas pelos professores com os seus alunos.
