Building a Distribution: Openharmony and Openmandriva
Two different approaches to building a distribution: OpenHarmony and OpenMandriva Bernhard "bero" Rosenkränzer <[email protected]> FOSDEM 2021 -- February 6, 2021 1 MY CONTACT: [email protected], [email protected] Way more important than that, he also feeds LINKEDIN: dogs. https://www.linkedin.com/in/berolinux/ Bernhard "bero" Rosenkränzer I don't usually do "About Me", but since it may be relevant to the topic: Principal Technologist at Open Source Technology Center since November 2020 President of the OpenMandriva Association, Contributor since 2012 - also a contributor to Mandrake back in 1998/1999 2 What is OpenHarmony? ● More than an operating system: Can use multiple different kernels (Linux, Zephyr, ...) ● Key goal: autonomous, cooperative devices -- multiple devices form a distributed virtual bus and can share resources ● Initial target devices: Avenger 96 (32-bit ARMv7 Cortex-A7+-M4), Nitrogen 96 (Cortex-M4) ● Built with OpenEmbedded/Yocto - one command builds the entire OS ● Fully open, developed as an Open Source project instead of an inhouse product from the start. ● For more information, visit Stefan Schmidt's talk in the Embedded devroom, 17.30 and/or talk to us at the Huawei OSTC stand. 3 What is OpenMandriva? ● A more traditional Linux distribution - controlled by the community, continuing where Mandriva left off after the company behind it went out of business in 2012. Its roots go back to the first Mandrake Linux release in 1998. ● Originally targeting only x86 PCs - Support for additional architectures (aarch64, armv7hnl, RISC-V) added later ● Repositiories contain 17618 packages, built and updated individually, assembled into an installable product with omdv-build-iso or os-image-builder. -
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. -

PINEPHONE USER MANUAL - QUICK START GUIDE (EN) 1 Package contents ● User Manual - Quick Start Guide (x1) ● PinePhone (x1) ● USB-C power cable (x1) 2 Safety precautions and recycling 2.1 Cautions Before using the device please read this manual carefully. Notes for safe operation: ● The PinePhone should be charged using a 15W (5V 3A) USB-PD power adapter. Charging at a higher voltage may result in damage to the device. ● The PinePhone will only operate when its internal temperature is between 5°C and 65°C. It should never be operated with an external temperature lower than -20°C or higher than 40°C. ● Do not puncture, disassemble, strike or squeeze the battery. Old batteries need to be disposed of in accordance with local regulations (see section 2.2). ● Do not expose the device to direct sunlight, water or high levels of humidity. ● In the event of overheating, power off the PinePhone and let it cool for 15 minutes. ● Comply with local regulation pertaining to using mobile devices. This extends to and includes use of the device in public spaces, when operating motor vehicles and heavy machinery. 2.2 Recycling of components and batteries Recycling any PinePhone components should be done according to local regulation. This may require you to dispose of the phone or its parts at a local recycling centre or at a designated container. Please consult local legislation for details. Batteries should never, under any circumstances, be disposed of with general household waste. The end user is legally obliged to return used batteries. Batteries can be returned to us to be disposed of. -

Digital Forensics Analysis of Ubuntu Touch on Pinephone
electronics Article Digital Forensics Analysis of Ubuntu Touch on PinePhone Yansi Keim *,† , Yung Han Yoon *,† and Umit Karabiyik * Department of Computer and Information Technology, Purdue University, West Lafayette, IN 47907, USA * Correspondence: [email protected] (Y.K.); [email protected] (Y.H.Y.); [email protected] (U.K.) † These authors contributed equally to this work. Abstract: New smartphones made by small companies enter the technology market everyday. These new devices introduce new challenges for mobile forensic investigators as these devices end up becoming pertinent evidence during an investigation. One such device is the PinePhone from Pine Microsystems (Pine64). These new devices are sometimes also shipped with OSes that are developed by open source communities and are otherwise never seen by investigators. Ubuntu Touch is one of these OSes and is currently being developed for deployment on the PinePhone. There is little research behind both the device and OS on what methodology an investigator should follow to reliably and accurately extract data. This results in potentially flawed methodologies being used before any testing can occur and contributes to the backlog of devices that need to be processed. Therefore, in this paper, the first forensic analysis of the PinePhone device with Ubuntu Touch OS is performed using Autopsy, an open source tool, to establish a framework that can be used to examine and analyze devices running the Ubuntu Touch OS. The findings include analysis of artifacts that could impact user privacy and data security, organization structure of file storage, app storage, OS, etc. Moreover, locations within the device that stores call logs, SMS messages, images, and videos are reported. -

Computer Engineering Subject
DIRECTORATE OF TECHNICAL EDUCATION, CHENNAI-25 DIPLOMA EXAMINATIONS-APRIL-2019 DEPT : COMPUTER ENGINEERING SUBJECT : MOBILE COMPUTING QCODE/SUB CODE : 915/35262 PART -A 1. Define LAN.[ 2 marks] A local-area network (LAN) is a computer network that spans a relatively small area. Most often, LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. 2. What is meant by Adhoc? [ 2 marks] An ad hoc network is a network that is composed of individual devices communicating with each other directly. The term implies spontaneous or impromptu construction because these networks often bypass the gatekeeping hardware or central access point such as a router 3. What is GSM network? [ 2 marks] GSM stands for Global System for Mobile Communication. GSM is the most widely accepted standard in telecommunications and it is implemented globally. It is a digital cellular technology used for transmitting mobile voice and data services. 4. Write the limitation of GPRS. [ 2 marks] Although GPRS will provide better data rates than is currently available, there are some limitations. • Speeds of 177.2kbps would require a user to use all eight timeslots without any error protection - which simply won't happen. Initial terminals are likely to use only 1-3 timeslots anyway, limiting the available bandwidth to a GPRS user. • When GPRS packets are sent to a destination they are sent in all different directions - allowing for the potential for one or some of those packets to be corrupted or even lost altogether during the data transmission over the radio link.
