Release Notes and Errata
OpenMandriva Lx 4.3rc Release Notes The OpenMandriva Lx teams are pleased to announce the availability of OpenMandriva Lx 4.3rc. Available Media This release is available as a live media DVD or USB flash drive (memory stick), downloadable in ISO format. These are available on our downloads page. USB flash drive installation is usually noticeably faster. As always speed depends on many factors. Live media means you are able to run OpenMandriva Lx straight from a DVD or memory stick (see below) and try it before installing it. You may also install the system to hard disk either from the running live image or from the boot manager. Available ISO files are: •x86_64 KDE Plasma desktop full featured (includes the most common used functionalities, multimedia and office software). •znver1 Plasma: we have also built a version specifically for current AMD processors (Ryzen, ThreadRipper, EPYC) that outperforms the generic (x86_64) version by taking advantage of new features in those processors. znver1 is for the listed processors (Ryzen, ThreadRipper, EPYC) only, do not install on any other hardware. Installable images are offered for the Pinebook Pro, Raspberry Pi 4B, Raspberry Pi 3B+, Synquacer, Cubox Pulse and generic UEFI compatible devices (such as most aarch64 server boards) System requirements OpenMandriva Lx 4.3 requires at least 2048 MB of memory and at least 10 GB of hard drive space (see below for known issues with partitioning). Important Note: Graphics Hardware: The KDE Plasma Desktop requires a 3D graphics card that supports OpenGL 2.0 or above. We recommend using AMD, Intel, Adreno or VC4 graphics chips. -

Introduction to Linux
Presentation to U3A - Linux Introduction 8 June 2019 – Terry Schuster - [email protected] What is Linux? https://en.wikipedia.org/wiki/Linux https://www.iotforall.com/linux-operating-system-iot-devices/ In simple terms, Linux is an operating system which was developed to be a home-built version of UNIX, one of the first operating systems which could be run on different brands of mainframe computers with quite different types of hardware. Linux has developed to the extent that it is the leading operating system on servers and other big iron systems such as mainframe computers, and the only OS used on TOP500 supercomputers (since November 2017, having gradually eliminated all competitors). It is used by around 2.3 percent of desktop computers. The Chromebook, which runs the Linux kernel-based Chrome OS, dominates the US K–12 education market. In the mid 2000’s, Linux was quickly seen as a good building block for smartphones, as it provided an out- of-the-box modern, full-featured Operating System with very good device driver support, and that was considered both scalable for the new generation of devices and had the added benefit of being royalty free. It is now becoming very common in IoT devices, such as smart watches/refrigerators, home controllers, etc. etc. BTW, Tux is a penguin character and the official brand character of the Linux kernel. Originally created as an entry to a Linux logo competition, Tux is the most commonly used icon for Linux, although different Linux distributions depict Tux in various styles. The character is used in many other Linux programs and as a general symbol of Linux. -

KDE Plasma 5
Arvo Mägi KDE Plasma 5 Tallinn, 2017 1 Sissejuhatus KDE töökeskkonnale pani aluse saksa programmeerija Matthias Ettrich 14.10.1996. 2016. a oktoobris sai populaarne KDE seega 20. aastaseks. Hea ülevaate KDE ajaloost annab artikkel „19 Years of KDE History: Step by Step.” KDE 4.14 ilmumisega oli KDE saavutanud kasutusküpsuse, kuid edasine areng kippus takerduma – vaja oli põhimõttelisi uuendusi. Otsustati võtta kasutusele iseseisvatel moodulitel põhinev KDE 5 arhitektuur – Qt/Frameworks. Kõik KDE rakendusprogrammid, sh Plasma 5 töölaud, kasutavad ainult konkreetse rakenduse jaoks vajalikke mooduleid. Varem kasutati kõigi rakenduste jaoks ühist suurt teeki, mis raskendas muudatuste tegemist ja pidurdas arendustööd. Qt on C++ programmeerimiskeskkond. Pikaajalise toega Qt 5.9 LTS ilmus 31. mail 2017. KDE Frameworks on 70 moodulist koosnev komplekt, mis lihtsustab Qt keskkonnas KDE programmide koostamist. Frameworks veaparandused ja täiendused ilmuvad iga kuu. KDE Plasma 5 töölaud põhineb KDE Frameworksil (KF5). Töölaua veaparandused ilmuvad iga kuu, vajadusel mitu korda kuus, uued versioonid kord kvartalis. Plasma 5.8 LTS, mis on pikaajalise toega (18 kuud), ilmus 4.10.2016, veidi enne KDE 20. aastaseks saamist. Plasma 5.10 ilmus 30.05.2017. Järgmine pikaajalise toega Plasma 5.12 ilmub 2018. a jaanuaris. Plasma 5 töölaud on pälvinud palju kiitvaid hinnanguid ja sobib igapäevaseks tööks. Eeldab kaasaegset, mitme tuumaga protsessori ja piisava mäluga (vähemalt 4 GB) arvutit. SSD kettalt töötab välkkiirelt. Töölaud on keskkond rakendusprogrammide käivitamiseks ja kasutamiseks. KF5-le on üle viidud kõik KDE põhirakendused (failihaldur Dolphin, pildinäitaja Gwenview, konsool Konsole, teksti- redaktor Kate, ekraanitõmmise võtja Spectacle, videoredaktor Kdenlive, plaadikirjutaja K3b jt). Need on KDE Applications koosseisus, mille uued versioonid ilmuvad kolm korda aastas, veaparandused kord kuus. -

Chapter 7 Package Management
Chapter 7 Package Management CERTIFICATION OBJECTIVES 7.01 The Red Hat Package Manager ✓ Two-Minute Drill 7.02 More RPM Commands Q&A Self Test 7.03 Dependencies and the yum Command 7.04 More Package Management Tools fter installation is complete, systems are secured, filesystems are configured, and other initial setup tasks are completed, you still have work to do. Almost certainly before your system is in the state you desire, you will be required to install or remove packages. To make sure the right updates are installed, you need to know how to get a system working with ARed Hat Subscription Management (RHSM) or the repository associated with a rebuild distribution. To accomplish these tasks, you need to understand how to use the rpm and yum commands in detail. Although these are “just” two commands, they are rich in detail. Entire books have been dedicated to the rpm command, such as the Red Hat RPM Guide by Eric 344 Chapter 7 Package Management Foster-Johnson. For many, that degree of in-depth knowledge of the rpm command is no longer necessary, given the capabilities of the yum command and the additional package management tools provided in RHEL 7. CERTIFICATION OBJECTIVE 7.01 The Red Hat Package Manager One of the major duties of a system administrator is software management. New applications are installed. Services are updated. Kernels are patched. Without the right tools, it can be difficult to figure out what software is on a system, what is the latest update, and what applications depend on other software. -

Introduction to Linux Steve Bogol [email protected] Part I What is Linux? Linux Mainstream Video Linux Nutshell What is Linux? ● A free operating system created by Linus Torvalds in 1991. ● Based off of Unix using GNU tools and a kernel made by Linus. ● Originally called “Freax” (“free” + “freak” + “X”). ● More focused on multiple users than a single user (Windows/Mac). ● Traditionally command line primary and GUI secondary. ● Free to change and redistribute the changed version. Distributions (distros) Wikipedia: A Linux distribution (often called a distro for short) is an operating system made from a software collection, which is based upon the Linux kernel and, often, a package management system.

Part II Using Linux Demo Basics, Hints, & Tips Shells What is a shell? “Simply put, the shell is a program that takes your commands from the keyboard and gives them to the operating system to perform. In the old days, it was the only user interface available on a Unix computer. Nowadays, we have graphical user interfaces (GUIs) in addition to command line interfaces (CLIs) such as the shell.” -- linuxcommand.org Connecting to a Remote Server ● Connect using a SSH client. ● A SSH client is standard on a Mac and Linux OS. ● Windows users have to install a SSH client such as Putty. -
