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. -
