System Calls System Calls
System calls We will investigate several issues related to system calls. Read chapter 12 of the book Linux system call categories file management process management error handling note that these categories are loosely defined and much is behind included, e.g. communication. Why? 1 System calls File management system call hierarchy you may not see some topics as part of “file management”, e.g., sockets 2 System calls Process management system call hierarchy 3 System calls Error handling hierarchy 4 Error Handling Anything can fail! System calls are no exception Try to read a file that does not exist! Error number: errno every process contains a global variable errno errno is set to 0 when process is created when error occurs errno is set to a specific code associated with the error cause trying to open file that does not exist sets errno to 2 5 Error Handling error constants are defined in errno.h here are the first few of errno.h on OS X 10.6.4 #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* No such file or directory */ #define ESRCH 3 /* No such process */ #define EINTR 4 /* Interrupted system call */ #define EIO 5 /* Input/output error */ #define ENXIO 6 /* Device not configured */ #define E2BIG 7 /* Argument list too long */ #define ENOEXEC 8 /* Exec format error */ #define EBADF 9 /* Bad file descriptor */ #define ECHILD 10 /* No child processes */ #define EDEADLK 11 /* Resource deadlock avoided */ 6 Error Handling common mistake for displaying errno from Linux errno man page: 7 Error Handling Description of the perror () system call. -

The OS examines the call parameters The OS performs the requested function The OS saves its state (and call results) The OS returns control of the CPU to the caller Copyright ©: University of Illinois CS 241 Staff 6 Steps for Making a System Call -
(Bachelor, Master, Or Phd) and Which Software Tools to Use How to Write A
2.6.2016 How to write a thesis (Bachelor, Master, or PhD) and which software tools to use SciPlore Home Projects Publications About & Contact How to write a thesis (Bachelor, Master, or PhD) and Home / HOW TOs, sciplore mindmapping / which software tools to use How to write a thesis (Bachelor, Master, or PhD) and which software tools to use Previous Next How to write a thesis (Bachelor, Master, or PhD) and which software tools to use Available translations: Chinese (thanks to Chen Feng) | Portuguese (thanks to Marcelo Cruz dos Santos) | Russian (thanks to Sergey Loy) send us your translation Writing a thesis is a complex task. You need to nd related literature, take notes, draft the thesis, and eventually write the nal document and create the bibliography. Many books explain how to perform a literature survey and how to write scholarly literature in general and a thesis in particular (e.g. [1-9]). However, these books barely, if at all, cover software tools that help in performing these tasks. This is surprising, because great software tools that can facilitate the daily work of students and researchers are available and many of them for free. In this tutorial, we present a new method to reviewing scholarly literature and drafting a thesis using mind mapping software, PDF readers, and reference managers. This tutorial focuses on writing a PhD thesis. However, the presented methods are likewise applicable to planning and writing a bachelor thesis or master thesis. This tutorial is special, because it integrates the management of PDF les, the relevant content in PDFs (bookmarks), and references with mind mapping and word processing software. -

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 -

KDE Published : 2017-06-26 License : GPLv2+ 1 KDE DU POINT DE VUE D'UN DÉVELOPPEUR 1. AVEZ-VOUS BESOIN DE CE LIVRE ? 2. LA PHILOSOPHIE DE KDE 3. COMMENT OBTENIR DE L'AIDE 2 1. AVEZ-VOUS BESOIN DE CE LIVRE ? Vous devriez lire ce livre si vous voulez développer pour KDE. Nous utilisons le terme développement très largement pour couvrir tout ce qui peut conduire à un changement dans le code source, ce qui inclut : Soumettre une correction de bogue Écrire une nouvelle application optimisée par la technologie KDE Contribuer à un projet existant Ajouter de la fonctionnalité aux bibliothèques de développement de KDE Dans ce livre, nous vous livrerons les bases dont vous avez besoin pour être un développeur productif. Nous décrirons les outils que vous devrez installer, montrer comment lire la documentation (et écrire la vôtre propre, une fois que vous aurez créé la nouvelle fonctionnalité !) et comment obtenir de l'aide par d'autres moyens. Nous vous présenterons la communauté KDE, qui est essentielle pour comprendre KDE parce que nous sommes un projet « open source », libre (gratuit). Les utilisateurs finaux du logiciel n'ont PAS besoin de ce livre ! Cependant, ils pourraient le trouver intéressant pour les aider à comprendre comment les logiciels complexes et riches en fonctionnalités qu'ils utilisent ont vu le jour. 3 2. LA PHILOSOPHIE DE KDE Le succès de KDE repose sur une vue globale, que nous avons trouvée à la fois pratique et motivante. Les éléments de cette philosophie de développement comprennent : L'utilisation des outils disponibles plutôt que de ré-inventer ceux existants : beaucoup des bases dont vous avez besoin pour travailler font déjà partie de KDE, comme les bibliothèques principales ou les « Kparts », et sont tout à fait au point.
