On March 19th, LG introduced webOS Open Source Edition with the intention of opening up webOS again to the world of development to move beyond TVs. This is the second time an open-source version of webOS has been released, the first coming under the failed tenure of HP back in 2011.
LG Chief Technology Officer Dr. I.P. Park. “webOS has come a long way since then and is now a mature and stable platform ready to move beyond TVs.”
webOS Open Source Edition Architecture
The following figure shows the overall architecture of webOS Open Source Edition (OSE). webOS OSE consist of a set of layers: Core Applications, Application Framework, Managers & Services, Base Components, and BSP/Kernel.
webOS OSE has Core applications as the top layer and this layer includes System UI and System app. System UI includes apps that are related to the basic user interface, such as Home Launcher and Notification. These apps are usually implemented using QML. System app includes Settings app and web browser. Settings app is used to control the system properties and implemented using Enact. As a web browser, the Chromium browser is used. Application Framework
The SDK provides a development environment for web apps and services. In this release of webOS OSE, we provide a CLI-based SDK for developing and installing web apps and services. Web apps can be packaged with services that are developed using Node.js. For more details on development/packaging of web apps and services, see Command Line Interface.
Managers & Services
Managers & Services layer includes the following components. System and Application Manager System and Application Manager (SAM) oversees the behavior of apps. SAM manages each app throughout its lifecycle, including the installation, launch, termination, and removal of the app. There are two types of apps in webOS Open Source Edition: native app and web app. In case of a web app, actual launching and management are performed by Web Application Manager as described below.
Web Application Manager
Web Application Manager (WAM) is responsible for launching and managing web apps. In addition, WAM performs CPU usage optimization, status monitoring and recovery processing, and access privileges management, all based on the running status of web apps.
Luna Surface Manager
Luna Surface Manager (LSM) is a component that works as a graphics manager. LSM displays graphical elements on the screen, manages the composition of these elements, and performs the event handling for input devices such as keyboard and pointer. LSM is also responsible for the execution and management of System UI, such as Home Launcher and Notification. LSM is implemented using Qt, and System UI is implemented using QML.
Activity Manager is responsible for managing and executing activities requested from services. An activity is requested along with a specific condition, and it is triggered when the condition is met. You can configure the activity to perform tasks such as automatic execution of specific services, callback requests, and so on.
uMediaServer (uMS) is a module that works as a server for the webOS media framework. uMS provides interfaces for media playback, manages resources, pipelines, and their policies, and manages the lifecycle of the media player.
Base Components layer includes the following components.
LS2 LS2, also called Luna Bus, is a system bus used by webOS OSE. LS2 manages the interface registration and invocation required for the interconnection among apps and services. Originally based on D-bus, LS2 has been enhanced to optimize the performance for embedded device environment. Web Engine
Chromium also includes browser logics a.k.a. Chromium browser which webOS OSE provides as the default browser app.
DB8 is an embedded JSON database that supports data storing and retrieving in the structure of key-value store. webOS OSE uses LevelDB as the back-end database. The default service associated with DB8 is the com.webos.db. The com.webos.tempdb, which allows you to configure temporary storage in memory, is also provided.
BSP/Kernel layer consists of several components to support Raspberry Pi 3. Typically, it provides evdev for event processing, Mesa for graphics support, and Wi-Fi and wired LAN for connectivity.

So did you guys see that smartwatch calling that Audi at CES? Turns out it's openwebos!
Exclusive: The hottest smartwatch of CES isn't running Android Wear — it's Open webOS LG and Audi's smartwatch collaboration is the most desirable wearable of CES 2015, and while the carmaker says it's just a prototype, the device offers a tantalizing glimpse of future LG wearables. Or at worst an agonizing look at a beautiful watch we'd love to own. We tracked down the Audi/LG watch — still officially nameless, by the way — in Las Vegas today, and we can exclusively reveal that it's not running Android Wear as originally believed. In fact, it's packing completely different software based on LG's Open webOS. Source: http://www.androidcentral.com/lg-audi-watch-android-wear-webos
HP webOS Cloud Services to end January 15, 2015
Cloud services support for webOS devices will be ending on January 15, 2015. We appreciate our customer's loyalty the webOS platform. But now, more than three (3) years after the last device was sold, only a small fraction of the devices are still connecting. Therefore, the time has come to shut down the services.
All devices running webOS devices will continue to run after the cloud services are terminated. However, they will no longer be able to:
Download new apps or updates. The HP App Catalog will be unavailable after the shutdown Backup or restore devices from the cloud Setup new devices Recover lost passwords The HP App Catalog will stop supporting new app purchases on November 1, 2014
Updates may be posted by developers until November 10, 2014 and users can download any available updates until the services shut down You should make arrangements to backup or transfer your contacts, etc.prior to the service shutdown on January 15, 2015 You will no longer be able to backup, restore, reset or initialize a webOS device as of January 15, 2015 There will be additional reminders as the final shutdown approaches. An FAQ can be found at
10/15/14 Announcement to users and developers 11/1/14 New app purchases end 11/10/14 App update submissions end 1/15/15 Public shutdown of services Source: HP webOS Cloud Services Mass Email
Ok, this is not exactly "Future" webOS gadgets but at one point it time it looks like they were. On January 2nd, Dieter Bohn wrote an article for the Verge titled, "The lost secrets of webOS" that is a very interesting read. Dieter reveils gadgets on the planning board of HP before Leo killed the entire webOS project. In the article he reveils future gadgets code named Twain, Mako, Sapphire, & Embark.
The Twain is an interesting piece of hardware which looked to be ahead of its time a bit as we are seeing tablets like this now.
Dieter also reveils that the iPad 2 is what scared them all off. It was thinner and lighter than the Touchpad. had they rode it out, who knows what webOs could have been today.
If you are a webOS fan, take a moment and read the article: http://www.theverge.com/2014/1/2/5264580/the-lost-secrets-of-webos
