Android
Linux

The emulator is software on a computer system that behaves like another computer system. When I am talking about Android Emulators for Linux, it means a program for Linux that runs like the Android environment. It is used by developers and testers to test their apps for Android using the Linux system. You can run Android apps and games on your Linux system. Emulators are also used by gamers to run Android games on their system. I have already listed best Android Emulators for PC but that basically included Android Emulators for Windows and Mac. So, I decided to make a dedicated list of Android Emulators for Linux.

From Nexus to Android One: a brief history of purist Android phones

Filed under
Android

Android has been around for so long, and in so many forms, that the open-source operating system has evolved on multiple fronts thanks to the frantic competition among the many vendors using the platform.

For all the bells and whistles of Samsung, LG and HTC, there’s always been a market for something a little purer – a 'stock' OS that strips away all the third-party bloat for an experience that’s as close to Google’s vision of Android as it’s possible to get.

From the evolution of Google's Nexus smartphone range (and their successors, the improving Google Pixel phones) to the simultaneous innovation of Android One, pure Android devices have carved out more than one niche for themselves. It’s been quite the journey, and the story isn’t over yet...

  • Me, at Akademy 2018 - Winds of Change - FOSS in India Recap (late post

    Akademy is an annual conference organized by the KDE Community. It’s the place where contributors of all kinds from past and present meet, showcase their work and discuss things that shape the future of the KDE Software. This year's Akademy was held in the TU Wien, in the beautiful and historic city of Vienna, Austria.

    First of all, I'd like to apologize for being late on this post as just after reaching home, I had a minor motorcycle accident, and which was followed shortly by prolonged illness.

    I've been a KDE guy since the beginning of my technology career as an open source evangelist, entrepreneur, and developer. This year, I got the opportunity to showcase my work in front of the great people I've always admired.

    [...]

    The current state of India in regards to Free and Open Source Software is somewhat optimistic, with more and more states of India bringing in IT policies which gives priority to free and open source solutions.

  • Modern KDE on FreeBSD

    New stuff in the official FreeBSD repositories! The X11 team has landed a newer version of libinput, opening up the way for KDE Plasma 5.14 in ports. That’s a pretty big update and it may frighten people with a new wallpaper.

    What this means is that the graphical stack is once again on-par with what Plasma upstream expects, and we can get back to chasing releases as soon as they happen, rather than gnashing our teeth at missing dependencies. The KDE-FreeBSD CI servers are in the process of being upgraded to 12-STABLE, and we’re integrating with the new experimental CI systems as well. This means we are chasing sensibly-modern systems (13-CURRENT is out of scope).

  • KDE4 on FreeBSD, post-mortem

    The KDE-FreeBSD team has spent the past month or more, along with FreeBSD ports committers and maintainers who have other KDE4-related ports, in bringing things up-to-date with recent KDE-Frameworks-based releases, with hunting down alternatives, and with making the tough call that some things are just going away. Thanks to Rene for doing the portmgr commits to clean it up (r488762, r488763, r488764 and followups to remove KDE4-options from other ports) .

  • Interview with Phoenix

    What I love about Krita is that it doesn’t take up that much RAM compared to other softwares I have used. It makes it really easy to record speedpaints for YouTube.

  • [Krita] Statistics Are Fun!

    Collectively we removed 648,887 lines of code and added 996,142 lines of code. Of course… Lines of code and numbers of commits doesn’t say a whole lot. But we’ve currently got 580,268 lines of C++, 12,054 lines of Python code out of a total of 607,193 lines of code. There are 30 libraries, 151 plugins, 243 automated tests (of which 5 are failing).

  • New home page =D

    Using Vuetify framework, that is built above Vue.Js I was able to build a new landing page with information about me and the stuff that I do. On that page you will be able to find my projects, presentations and contact information. I’ve also added a page of Tips & Tricks with content that I think that has value.

OPTPOLINES - Formerly Relpolines, Lower Overhead To Retpolines For Spectre Mitigation

Filed under
Linux
Security

It's been nearly one year to the day since the Spectre and Meltdown vulnerabilities were made public. While the security vulnerabilities were quickly buttoned up in the Linux space, kernel developers continue working to offset the performance overhead introduced by these mitigations. They made a lot of overhead reductions in 2018 while still there are some patch-sets pending still for bettering the experience. One of these patch-sets was known as "Relpolines" but now has been updated and morphed into what is being called Optpolines.

Relpolines were announced a few months ago by a VMware developer as having lower overhead than Retpolines -- the return trampolines introduced as part of the Spectre mitigations back in January. The dynamic indirect call promotion work by VMware has been working on pairing relative calls and trampolines to reduce the overall Retpoline overhead. VMware found with their original patches it could deliver a 10% performance improvement to the Nginx web server, +4% for Redis, and other minor performance improvements -- well, recovering previously lost performance.

What Is Ubuntu? The Past and Present of the Ubuntu Linux Distro

Filed under
Ubuntu

Ubuntu is the most popular Linux distribution in the world. It may (or may not) be the best, but it is definitely the most popular. The distribution, or packaged “brand” of Linux, is developed by Canonical Ltd. for use on desktops, servers, and many other applications.

Ubuntu is also the most popular operating system in the cloud. It’s the operating system Google built its Android development tools around. Ubuntu was the first Linux distribution supported by Valve for Steam. When most people think of Linux, they’re probably thinking about Ubuntu.

  • What is AOSP? Android Open Source Project, the ‘Android without Google’

    AOSP is the acronym for Android Open Supply Challenge ; that’s, ‘Android Open Source Project’. So it's simply the supply code of Android, the cellular working system of the Mountain View firm. However what’s it for? Its fundamental software is by OEMs; cellular producers obtain AOSP and make their 'ROM inventory', but additionally serves as the premise for customized ROMs and forks. AOSP, or Android Open Supply Challenge, isn’t the identical as Android Inventory . Whereas AOSP is the supply code of the working system, Android Inventory is the 'pure model' with out bloatware of any sort and solely with apps and Google providers, in addition to the native launcher. AOSP, nevertheless, is the premise of Android Vanilla , which is the model that’s distributed to smartphone producers and is topic to modifications. On it, the producer's personal purposes and providers are launched, and naturally the customization layer and the variations which can be essential for particular elements to work.

  • Introducing OpenDrop, an open-source implementation of Apple AirDrop written in Python

    A group of German researchers recently published a paper “A Billion Open Interfaces for Eve and Mallory: MitM, DoS, and Tracking Attacks on iOS and macOS Through Apple Wireless Direct Link”, at the 28th USENIX Security Symposium (August 14–16), USA. The paper reveals security and privacy vulnerabilities in Apple’s AirDrop file-sharing service as well as denial-of-service (DoS) attacks which leads to privacy leaks or simultaneous crashing of all neighboring devices. As part of the research, Milan Stute and Alexander Heinrich, two researchers have developed an open-source implementation of Apple AirDrop written in Python – OpenDrop. OpenDrop is like a FOSS implementation of AirDrop. It is an experimental software and is the result of reverse engineering efforts by the Open Wireless Link project (OWL). It is compatible with Apple AirDrop and used for sharing files among Apple devices such as iOS and macOS or on Linux systems running an open re-implementation of Apple Wireless Direct Link (AWDL).

    DigiFi was founded by Joshua Jersey and Bradley Vanderstarren in 2014. It started its life as Promise Financial, an online lender, and raised $110 million in credit capital. It built up its own proprietary tech as there was no solution provider in 2014 offering an end-to-end loan origination platform that could automate the entire process. They sold off the tech to a large lending institution in 2017 and pivoted to DigiFi, one of the world’s first open source loan origination systems (LOS) which equips the lenders with flexible and modern tools to create unique platforms and digital experiences.

  • IT favors open source networking over Cisco ACI, VMware NSX

    Companies trying to avoid or lessen the use of expensive network automation software from Cisco and VMware are turning to open source tools that are often good enough for many tasks associated with managing complex modern networks. Cisco's application-centric infrastructure (ACI) and VMware's NSX are powerful technologies for operating networks built on the vendors' respective products. But many large enterprises have data centers filled with perfectly good multivendor hardware and software that very few organizations are willing to swap for an all Cisco or VMware alternative. Therefore, companies are turning to open source networking products, such as Ansible, Chef, Puppet and SaltStack, for automating many network-related chores across as much of the data center as possible, while relegating ACI and NSX to Cisco- or VMware-only portions of the network.
