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 Introduction to the X Window System Introduction to X's Anatomy
An Introduction to the X Window System Robert Lupton This is a limited and partisan introduction to ‘The X Window System’, which is widely but improperly known as X-windows, specifically to version 11 (‘X11’). The intention of the X-project has been to provide ‘tools not rules’, which allows their basic system to appear in a very large number of confusing guises. This document assumes that you are using the configuration that I set up at Peyton Hall † There are helpful manual entries under X and Xserver, as well as for individual utilities such as xterm. You may need to add /usr/princeton/X11/man to your MANPATH to read the X manpages. This is the first draft of this document, so I’d be very grateful for any comments or criticisms. Introduction to X’s Anatomy X consists of three parts: The server The part that knows about the hardware and how to draw lines and write characters. The Clients Such things as terminal emulators, dvi previewers, and clocks and The Window Manager A programme which handles negotiations between the different clients as they fight for screen space, colours, and sunlight. Another fundamental X-concept is that of resources, which is how X describes any- thing that a client might want to specify; common examples would be fonts, colours (both foreground and background), and position on the screen. Keys X can, and usually does, use a number of special keys. You are familiar with the way that <shift>a and <ctrl>a are different from a; in X this sensitivity extends to things like mouse buttons that you might not normally think of as case-sensitive. -

1. D-Bus a D-Bus FAQ Szerint D-Bus Egy Interprocessz-Kommunikációs Protokoll, És Annak Referenciamegvalósítása
Az Udev / D-Bus rendszer - a modern asztali Linuxok alapja A D-Bus rendszer minden modern Linux disztribúcióban jelen van, sőt mára már a Linux, és más UNIX jellegű, sőt nem UNIX rendszerek (különösen a desktopon futó változatok) egyik legalapvetőbb technológiája, és az ismerete a rendszergazdák számára lehetővé tesz néhány rendkívül hasznos trükköt, az alkalmazásfejlesztőknek pedig egyszerűen KÖTELEZŐ ismerniük. Miért ilyen fontos a D-Bus? Mit csinál? D-Bus alapú technológiát teszik lehetővé többek között azt, hogy közönséges felhasználóként a kedvenc asztali környezetünkbe bejelentkezve olyan feladatokat hajtsunk végre, amiket a kernel csak a root felasználónak engedne meg. Felmountolunk egy USB meghajtót? NetworkManagerrel konfiguráljuk a WiFi-t, a 3G internetet vagy bármilyen más hálózati csatolót, és kapcsolódunk egy hálózathoz? Figyelmeztetést kapunk a rendszertől, hogy új szoftverfrissítések érkeztek, majd telepítjük ezeket? Hibernáljuk, felfüggesztjük a gépet? A legtöbb esetben ma már D-Bus alapú technológiát használunk ilyen esetben. A D-Bus lehetővé teszi, hogy egymástól függetlenül, jellemzően más UID alatt indított szoftverösszetevők szabványos és biztonságos módon igénybe vegyék egymás szolgáltatásait. Ha valaha lesz a Linuxhoz professzionális desktop tűzfal vagy vírusirtó megoldás, a dolgok jelenlegi állasa szerint annak is D- Bus technológiát kell használnia. A D-Bus technológia legfontosabb ihletője a KDE DCOP rendszere volt, és mára a D-Bus leváltotta a DCOP-ot, csakúgy, mint a Gnome Bonobo technológiáját. 1. D-Bus A D-Bus FAQ szerint D-Bus egy interprocessz-kommunikációs protokoll, és annak referenciamegvalósítása. Ezen referenciamegvalósítás egyik összetevője, a libdbus könyvtár a D- Bus szabványnak megfelelő kommunikáció megvalósítását segíti. Egy másik összetevő, a dbus- daemon a D-Bus üzenetek routolásáért, szórásáért felelős. -
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 -
