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 -

Leap 15.2 Retrospective told us that users value most the installer, stability, seamless migrations, and YaST. These would be then our strengths according to users! The distribution is often profiled as the more stable one and easy to use as there should be no radical or disruptive changes in between minor updates. Some users say It’s the KDE distribution. Box says “The Linux Distribution for Beginners and Pros” !"osing the Leap Gap ● CtLG is a SUSE driven effort to bring Leap closer to SUSE Linux Enterprise than ever before. This brings quite some challenges but also open some new opportunities. ● Unification of openSUSE Leap and SUSE Linux Enterprise 15 code streams and feature set. ● Concept of building a community distribution by combining rpms from openSUSE Backports (community part) and SUSE signed SLE rpms (Enterprise part). -

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. -

Smarter Balanced Technology Strategy Framework and Testing Device Requirements
The Smarter Balanced Technology Strategy Framework and Testing Device Requirements The Smarter Balanced Technology Strategy Framework and Testing Device Requirements The Smarter Balanced Technology Strategy Framework and Testing Device Requirements Smarter Balanced Assessment Consortium Smarter Balanced is a state-led consortium developing assessments aligned to the Common Core State Standards in English language arts/ literacy and mathematics that are designed to help prepare all students to graduate high school college- and career-ready. Introduction This report presents a framework for collective technology planning among the Smarter Balanced Assessment Consortium member states. The plan emphasizes the critical need for technology to support student learning with the Smarter Balanced Assessment System minimum requirements as context and milestones. The minimum requirements are based on expert judgments regarding instructional technology, district interviews, input and feedback from various national experts, specific guidance and direction from the Smarter Balanced executive team and the Technology Approach Work Group, and an independent review of data collected from the Smarter Balanced Technology Readiness Tool. These data and reviews indicate that the administration of online adaptive assessments, similar to those administered in a number of Smarter Balanced states at this time, can largely be executed with the hardware and infrastructure that exists in schools today. Key strategies for successful implementation of the Smarter Balanced Assessment System will include: • Implementing strategic approaches to testing schedules that leverage the testing window. • Evaluating and addressing any problems with actual bandwidth levels at a given school site (i.e. the pipeline throughout the school, not just the bandwidth to the school). • Ensuring continual basic maintenance and upkeep of existing assets. -
