Creating Meego Products in a Different Way and Faster - How to Change the Device Creation Creating MeeGo products in a different way and faster - How to change the device creation Pasi Nieminen CEO [email protected] +358 40 737 3907 www.nomovok.com 1 The Questions That I Try Answer Today How to make product faster & better in MeeGo world How/why to change the UX creation - QML? MeeGo for ARM, where is it now? Where to find companies to work on MeeGo? 2 About Us We create products build on Open Source technologies #1 MeeGo company Pioneer in Embedded Open Source Pioneer in commercial utilization of Open Source in embedded devices. Since 2001, more than 400 OSS deployment project delivered Employs 110 OSS experts globally 400 more in ZCOCO.net for deep Linux expertize Locations 3 Currently serving businesses in Japan, Germany, France, US, Finland and Korea. Insider's View to MeeGo - Where Are We Now? 4 Current MeeGo Deployment Status Currently FULL build & integration pipeline working Currently MeeGo-dev + QT4.7 + NOMOVOK Steel Rat UX running on STE U8500 / Freescale i.mx51 / Renesas AP4 (All ARMv7 optimized) / IA See our demo @ demo area, and NOMOVOK staff 5 Forget C++ & Native QT apps - Go for QML 6 MeeGo Apps – Faster QT4.7 enables QML apps Declarative UI XML + JS 3x faster app creation to QT native apps Performance almost equal to native QT apps, in future much faster (declarative GUI => GPU) 7 QML – hello world import Qt 4.7 Rectangle { id: page width: 500; height: 200 color: "lightgray" Text { id: helloText8 text: "Hello world!" y: 30 anchors.horizontalCenter: page.horizontalCenter font.pointSize: 24; font.bold: true } } QML - demo 9 Moving to Native Build Process from Cross compilation -Ready To Deploy Today 10 MeeGo Builds – a new way No cross compilation anymore, pure native builds No toolchain problems No manual patching / no branching Faster new versions Completely new way to build embedded products, and integrate to community versions 11 Build environment is the same as the target environment, including Building for Target HW operating system and hardware architecture Native Cross-compilation Build environment is completely different from the target environment. Build tools are On Target HW Emulated modified not to see/rely on the actual environment. Example: Maemo (ARM) app built in Ubuntu on x86 PC using Scratchbox Build environment is the Build environment is the same as the target actual target environment, environment, but emulated as virtual machine including real hardware. on another environment. Example: Maemo app built Example: Ubuntu ARM app built in Windows PC, in Maemo device with ARM. using a Virtual Machine emulating ARM. Ubuntu installed as the OS of this Virtual Machine. 12 Benefits of Native Build Systems Native on Target Native on Emulated Target 1. Build tools (compilers etc.) 1. No changes needed to environment or tools originally designed, and are still Build tools work as they do on native developed, for this as target. 2. Use of actual environment information 2. Get the actual environment 3. No limit to the performance of the VM host machine information from running system 4. Allow building in host desktop machines in multiple OS's 3. Always access to the latest tools and features for the environment 5. OS only limited by the virtualization SW support 4. No performance hit from extra 6. Most packages can be built in emulated environment computing layers 7. Success rate in tested packages: ~85-95% of Ubuntu packages built without modifications (Handhelds Mojo CELF2008: ~15000 packages) Yes, there are some cons: - Not all, i.e. smaller, devices have Yes, there are some cons: sufficient performance to be High performance hit due to the Virtual Machine emulation feasible build devices layer - Builds require significant computing Not all packages can be built unmodified with emulator power 13 Native build or modifications needed NOMOVOK Linux Build Service Hosted Linux binaries build service Optimized binaries Customers to drop in source codes and Means more performance with less power consumption and smaller memory footprint NOMOVOK process takes care of native (e.g. ARM kernel 20% improvement in build to deliver binary packages performance). Native builds – less problems Common components No tool and patching problems with cross Use of common components and technologies compilation build systems allows easy, secure access and use as part of the development process. No vendor lock Optimized target architecture and the Linux ups, open process. distribution Secure Native build can support a long list of target Each customer gets an own, separate and hardwares.

  • Linux Foundation to Host Meego Workgroup
    Linux Foundation To Host MeeGo Workgroup New Open Source Software Platform Backed by Intel and Nokia will Power the Next Generation of Computing Devices SAN FRANCISCO, February 15, 2010 – The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, today announced it will host the MeeGo project, the open source software platform for the next generation of computing devices. MeeGo combines Intel’s Moblin™ and Nokia’s Maemo projects into one Linux-based platform. MeeGo, announced today in a joint release by Intel and Nokia, will be deployed across many computing device types - including pocketable mobile computers, netbooks, tablets, mediaphones, connected TVs and in-vehicle infotainment systems, and brings together the leaders in computing and mobile communications as the project’s backers. MeeGo is designed for cross-device, cross-architecture computing and is built from the ground up for a new class of powerful computing devices. The workgroup will be hosted by the Linux Foundation as a fully open source project, encouraging community contributions in line with the best practices of the open source development model. The Linux Foundation expects MeeGo to be adopted widely by device manufacturers, network operators, software vendors and developers across multiple device types and for many organizations and developers to participate in the workgroup. “With MeeGo, you have the world’s leader in computing – Intel – uniting with the world’s leader in communications – Nokia – in a true open source project hosted at the Linux Foundation,” said Jim Zemlin, executive director at the Linux Foundation. “MeeGo has been built from the ground up for rich, mobile devices and will deliver choice to consumers without lock-in.

Question # 3 Do you know about Sailfish OS software availability? Answer:- Sailfish will be able to run most applications that were originally developed for MeeGo and Android, in addition to native Sailfish applications. This will give it a large catalogue of available apps on launch. Considering upon Jolla's declarations that Sailfish OS is be able to use software from following platforms Sailfish (natively created + ported like from Qt, Symbian, MeeGo - developers have reported that porting a Qt written software with Sailfish SDK takes a few hours only) Android applications are directly running in Sailfish OS. They are compatible as they are in third-party Android stores, with no needed modification (in most cases). MeeGo (because of backward compatibility thanks to MeeGo code legacy included in the Mer core) Unix and Linux (as Sailfish is Linux then using such a software is possible, especially RPM packages, either in terminal/console mode or with limitations implying from using Sailfish UI, if not ported and adjusted) HTML5 Read More Answers.

    Islander February 2011 Technology Update The Androids are coming! Report from the Mobile World Congress - formerly known as 3GSM This last week we attended the Mobile World Congress (MWC) in Barcelona, where the next generation of cellphones are showcased. In today‟s world where Apple has created and sharply led the smartphone race off the start line, leaving the once great (just two years ago) Nokia flailing in their wake, desperately trying to trip them up, like a bad loser, by issuing law suits. At the same time another competitor has quietly got on with what Nokia should have been doing by putting their energy into developing an alternative “complete smartphone software Editorial Technical solution” which offers better features than the iPhone. The new kid on the smart phone block is Google. Consultants Accenture referred last week at the MWC to their operating system software, Android, as a new phenomenon. At the show last week nearly every conversation ended up with one subject: Google and its Android Mobile Phone operating system. Nokia did do their best to overshadow the show debate for the week by announcing on the eve of MWC their decision to opt for Microsoft‟s Windows Phone 7 (WP7) platform as its primary smartphone operating system, rather than Android. Stephen Elop, CEO of Nokia, told reporters at the press conference that the decision was prompted by a desire to avoid a “duopoly” in the mobile industry between Google/Nokia and Apple and they wanted to create a third challenger. The two firms are positioning the alliance as the third major smartphone ecosystem alongside Apple‟s iOS and the Android community.

  • Download Android Os for Phone Open Source Mobile OS Alternatives to Android
    download android os for phone Open Source Mobile OS Alternatives To Android. It’s no exaggeration to say that open source operating systems rule the world of mobile devices. Android is still an open-source project, after all. But, due to the bundle of proprietary software that comes along with Android on consumer devices, many people don’t consider it an open source operating system. So, what are the alternatives to Android? iOS? Maybe, but I am primarily interested in open-source alternatives to Android. I am going to list not one, not two, but several alternatives, Linux-based mobile OSes . Top Open Source alternatives to Android (and iOS) Let’s see what open source mobile operating systems are available. Just to mention, the list is not in any hierarchical or chronological order . 1. Plasma Mobile. A few years back, KDE announced its open source mobile OS, Plasma Mobile. Plasma Mobile is the mobile version of the desktop Plasma user interface, and aims to provide convergence for KDE users. It is being actively developed, and you can even find PinePhone running on Manjaro ARM while using KDE Plasma Mobile UI if you want to get your hands on a smartphone. 2. postmarketOS. PostmarketOS (pmOS for short) is a touch-optimized, pre-configured Alpine Linux with its own packages, which can be installed on smartphones. The idea is to enable a 10-year life cycle for smartphones. You probably already know that, after a few years, Android and iOS stop providing updates for older smartphones. At the same time, you can run Linux on older computers easily.

For more than 15 years, operational GUIs for accelerator controls and some lab applications for equipment experts have been developed in Java, first with Swing and more CRITERIA FOR SELECTING A NEW GUI recently with JavaFX. In March 2018, Oracle announced that Java GUIs were not part of their strategy anymore [1]. TECHNOLOGY They will not ship JavaFX after Java 8 and there are hints In our evaluation of GUI technologies, we considered that they would like to get rid of Swing as well. the following criteria: This was a wakeup call for us. We took the opportunity • Technical match: suitability for Desktop GUI to reconsider all technical options for developing development and good integration with the existing operational GUIs. Our options ranged from sticking with controls environment (Linux, Java, C/C++) and the JavaFX, over using the Qt framework (either using PyQt APIs to the control system; or developing our own Java Bindings to Qt), to using Web • Popularity among our current and future developers: technology both in a browser and in native desktop little (additional) learning effort, attractiveness for new applications.
