Le schede Raspberry Pi 4 sono considerate come piattaforma hardware di riferimento. La piattaforma si sviluppa in un repository pubblico sotto licenza Apache 2.0, con lo sviluppo coordinato dalla comunit\u00e0, seguendo un modello di gestione condivisa.       <\/p>\n<p>La piattaforma webOS \u00e8 stata originariamente sviluppata da Palm nel 2008 ed \u00e8 stata utilizzata sugli smartphone Palm Pre e Pixie. Nel 2010, dopo l'acquisizione di Palm, la piattaforma \u00e8 passata nelle mani di Hewlett-Packard, che ha cercato di utilizzare questa piattaforma nelle proprie stampanti, tablet, laptop e PC. Nel 2012, HP ha annunciato il passaggio di webOS a un progetto open source indipendente e nel 2013 ha iniziato a rilasciare i codici sorgente dei suoi componenti. Nel 2013, la piattaforma \u00e8 stata acquistata da LG e ora \u00e8 utilizzata su oltre 70 milioni di televisioni e dispositivi di consumo LG. Nel 2018 \u00e8 stato fondato il progetto webOS Open Source Edition, attraverso il quale LG ha cercato di tornare a un modello di sviluppo aperto, coinvolgendo altri partecipanti e ampliando la gamma di dispositivi supportati in webOS.    <\/p>\n<p>L'ambiente del sistema webOS \u00e8 creato utilizzando strumenti e pacchetti di base OpenEmbedded, oltre a un sistema di build e a un insieme di metadati dal progetto Yocto. I componenti chiave di webOS includono il gestore di sistema e applicazioni (SAM, System and Application Manager), responsabile dell'esecuzione di applicazioni e servizi, e il Luna Surface Manager (LSM), che forma l'interfaccia utente. I componenti sono scritti utilizzando il framework Qt e il motore di rendering Chromium.      <\/p>\n<p>Il rendering avviene tramite un gestore composito che utilizza il protocollo Wayland. Per lo sviluppo di applicazioni personalizzate, si consiglia di utilizzare tecnologie web (CSS, HTML5 e JavaScript) e il framework Enact, basato su React, ma \u00e8 possibile anche creare programmi in C e C++ con un'interfaccia basata su Qt. L'interfaccia utente e le applicazioni grafiche integrate sono principalmente realizzate come programmi nativi scritti utilizzando la tecnologia QML. Per impostazione predefinita, viene offerto il launcher Home, ottimizzato per la gestione tramite schermi tattili e che propone un concetto di schede intercambiabili (invece di finestre).      <\/p>\n<\/p>\n<p>Per la memorizzazione dei dati in formato strutturato utilizzando il formato JSON viene utilizzato un archivio DB8, che utilizza come backend un database LevelDB. Per l'inizializzazione viene utilizzato bootd basato su systemd. Per l'elaborazione dei contenuti multimediali sono disponibili i sottosistemi uMediaServer e Media Display Controller (MDC), mentre per l'audio viene utilizzato PulseAudio. <a

l'aggiornamento automatico del firmware viene utilizzato OSTree e la sostituzione atomica delle partizioni (vengono creati due partizioni di sistema, una delle quali \u00e8 attiva mentre l'altra viene utilizzata per copiare l'aggiornamento).    <\/p>\n<p><center><img decoding=\"async\" alt=\"Rilascio della piattaforma webOS Open Source Edition 2.17\"
