PostmarketOS
postmarketOS (abbreviated as pmOS) is an operating system primarily for smartphones, based on the Alpine Linux distribution. postmarketOS was launched on 26 May 2017 with the source code available on GitHub before migrating to GitLab in 2018. It is capable of running different X and Wayland based user interfaces, such as Plasma Mobile, MATE, GNOME 3, and XFCE; later updates added support for Unity8 and Phosh. It is also capable of running Docker, if the device specific kernel has cgroups and relevant configs enabled. The project aims to provide a ten-year lifecycle for smartphones. Architecture Unlike many other projects porting conventional Linux distributions to Android phones, postmarketOS does not use the Android build system or userspace. Each phone has only one unique package, and flashable installation images are generated using the pmbootstrap tool. The project intends to support the mainline Linux kernel on all phones in the future, instead of the often outdated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosh
Phosh (portmanteau of '' phone'' and ''shell'') is a graphical user interface designed for mobile and touch-based devices. It is the default shell used on several mobile Linux operating systems including PureOS, Mobian, and Fedora Mobility. It is also an option on postmarketOS, Manjaro, and openSUSE. Development In August 2017, Purism, personal computing hardware vendors and developers of PureOS announced their intention to release a privacy-centric smartphone that ran a mobile-optimized version of their Linux-based operating system. With this announcement, Purism released mockups of Phosh that resembled a modified GNOME Shell. This eventually became known as the Librem 5. In April 2018, Purism started to publicly release documentation that referenced Phosh with updated mockups, and hired GNOME UI/UX developer Tobias Bernard to directly contribute to the shell. Despite the Librem 5 phone being delayed, Phosh received its first official release in October 2018, which was prima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plasma Mobile
Plasma Mobile is a Plasma variant for smartphones. It is currently available for the Pinephone, and supported devices for postmarketOS such as the OnePlus 6. It is shipped by several Linux distributions, such as postmarketOS and Manjaro. History After Plasma Active sponsor Coherent Theory (under the Make·Play·Live brand) had given up their ambitions to release a tablet computer, Blue Systems emerged as a new sponsor in 2015 and shifted the focus of Plasma's handheld work towards smartphones. However, this stopped in 2021, with the project now being maintained by volunteers. The official announcement of the new form-factor interface was on 25 July 2015 at Akademy, accompanied by a working prototype running on a Nexus 5. Pine64 began sales of their PinePhone mobile device, with the KDE Community Edition being made available as pre-orders on 1 December 2020. Technology Plasma Mobile uses KWin's Wayland session. Distributions shipping Plasma Mobile can choose to support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wayland (display Server Protocol)
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a ''Wayland compositor'', because it additionally performs the task of a compositing window manager. Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open-source community-driven project with the aim of replacing the X Window System with a modern, secure simpler windowing system in Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence. As part of its efforts, the Wayland project also develops a reference implementation of a Wayland compositor called ''Weston''. Overview The Wayland Display Server project was started by Red Hat developer Kristian Høgsberg in 2008. Beginning around 2010, Linux desktop graphics ...

ARM Architecture
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer (RISC) instruction set architectures for computer processors, configured for various environments. Arm Ltd. develops the architectures and licenses them to other companies, who design their own products that implement one or more of those architectures, including system on a chip (SoC) and system on module (SOM) designs, that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement these instruction set architectures and licenses these designs to many companies that incorporate those core designs into their own products. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a 26-bit address space that limited it to 64 MB of main memory. This limitation was removed in the ARMv3 series, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anbox
Anbox is a free and open-source compatibility layer that aims to allow mobile applications and mobile games developed for Android to run on Linux distributions. Canonical introduced Anbox Cloud, for running Android applications in a cloud environment. Anbox executes the Android runtime environment by using LXC (Linux Containers), recreating the directory structure of Android as a mountable loop image, while using native Linux kernel to execute applications. It makes use of Linux namespaces through LXC for isolation. Applications do not have any direct hardware access, all accesses are sent through the Anbox daemon. See also * Android-x86 - An open source project that makes an unofficial porting of Google's Android mobile operating system to run on devices powered by AMD and Intel x86 processors, rather than RISC-based ARM chips. * BlueStacks has developed an App Player for Windows and MacOS capable of running Android applications in a container. * The SPURV compatibility lay ...

Nokia N900
The Nokia N900 is a smartphone made by Nokia. It supersedes the Nokia N810. Its default operating system, Maemo 5, is a Linux-based OS originally developed for the Nokia 770 Internet Tablet. It is the first Nokia device based upon the Texas Instruments OMAP3 microprocessor with the ARM Cortex-A8 core. Unlike the three Nokia Internet tablets preceding it, the Nokia N900 is the first Maemo device to include phone functionality (quad-band GSM and 3G UMTS/HSDPA). The N900 functions as a mobile Internet device, and includes email, web browsing and access to online services, a 5-megapixel digital camera for still or video photography, a portable media player for music and video, calculator, games console and word processor, SMS, as well as mobile telephony using either a mobile network or VoIP via Internet (mobile or Wi-Fi). Maemo provides an X-terminal interface for interacting with the core operating system. It was launched at Nokia World on 2 September 2009 and was released in ...

Initramfs
In Linux systems, initrd (''initial ramdisk'') is a scheme for loading a temporary root file system into memory, to be used as part of the Linux startup process. initrd and initramfs refer to two different methods of achieving this. Both are commonly used to make preparations before the real root file system can be mounted. Rationale Many Linux distributions ship a single, generic Linux kernel image one that the distribution's developers create specifically to boot on a wide variety of hardware. The device drivers for this generic kernel image are included as loadable kernel modules because statically compiling many drivers into one kernel causes the kernel image to be much larger, perhaps too large to boot on computers with limited memory, or in some cases to cause boot-time crashes or other problems due to probing for nonexistent or conflicting hardware. This static-compiled kernel approach also leaves modules in kernel memory which are no longer used or needed, and raises the p ...

Virtual Keyboard
A virtual keyboard is a software component that allows the Input device, input of characters without the need for physical keys. The interaction with the virtual Computer keyboard, keyboard happens mostly via a touchscreen interface, but can also take place in a different form in Virtual reality, virtual or augmented reality. Types On a desktop computer, a virtual keyboard might provide an alternative input mechanism for users with disability, disabilities who cannot use a conventional keyboard, or for bi- or multilingualism, multi-lingual users who switch frequently between different character sets or alphabets, which may be confusing over time. Although hardware keyboards are available with dual keyboard layouts (e.g. Cyrillic/Latin letters in various national layouts), the on-screen keyboard provides a handy substitute while working at different stations or on laptops, which seldom come with dual layouts. Virtual keyboards can be categorized by the following aspects: * Virtu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross Compilation
A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. For example, a compiler that runs on a PC but generates code that runs on an Android smartphone is a cross compiler. A cross compiler is useful to compile code for multiple platforms from one development host. Direct compilation on the target platform might be infeasible, for example on embedded systems with limited computing resources. Cross compilers are distinct from source-to-source compilers. A cross compiler is for cross-platform software generation of machine code, while a source-to-source compiler translates from one coding language to another in text code. Both are programming tools. Use The fundamental use of a cross compiler is to separate the build environment from target environment. This is useful in several situations: * Embedded computers where a device has highly limited resources. For example, a microwave oven will have an ...

GNOME 3
GNOME 3 is the third major release of the GNOME desktop environment. A major departure from technologies implemented by its predecessors, GNOME 3 introduced a dramatically different user interface. It was the first GNOME release to utilize a unified graphical shell known as GNOME Shell. It also introduced support for the Wayland display protocol and added integration with other key technologies such as Flatpak during its development lifecycle. While loose planning began as early as 2004, it was not officially announced until 2008, and received an initial release in 2011. It was superseded by GNOME 40 in 2021. Features Much of GNOME 3's user interface changes were based-on attempts at simplification and rethinking of traditional desktop computing workflows. Eschewing the beige colors present in GNOME 2 in favor of a modern black and gray, a new look and feel was implemented, which became known as Adwaita. Possibly the single-most significant feature change that GNOME 3 introd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploit (computer Security)
An exploit (from the English verb ''to exploit'', meaning "to use something to one’s own advantage") is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to cause unintended or unanticipated behavior to occur on computer software, hardware, or something electronic (usually computerized). Such behavior frequently includes things like gaining control of a computer system, allowing privilege escalation, or a denial-of-service (DoS or related DDoS) attack. In lay terms, some exploit is akin to a 'hack'. Classification There are several methods of classifying exploits. The most common is by how the exploit communicates to the vulnerable software. A ''remote exploit'' works over a network and exploits the security vulnerability without any prior access to the vulnerable system. A ''local exploit'' requires prior access to the vulnerable system and usually increases the privileges of the person running the exploit past tho ...
