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.

OSS

While 2018 was a grand year for open-source and Linux as we've been recapping all of the highlights in recent days on Phoronix, it wasn't without some shortcomings or areas that have yet to pan out... As we end 2018, for some interesting New Year's Eve discussions in the forums, here is a look at some of the biggest Linux/open-source letdowns of the year.

Here are what I personally consider to be some of the biggest letdowns of the year. Feel free to chime in with your own open-source letdowns in the forums.

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.

System Monitoring Center is an Ideal Task Manager & Resource Monitor for Linux

Graphically monitoring the system resources may not be the best experience on Linux. The system monitoring tool that comes baked in with your desktop environment might limit the details. For instance, GNOME’s system monitor does not display the CPU frequency and temperatures. In addition, the default system monitor applications available for Linux usually aim for simplicity instead of providing detailed insights. Read more

  • How Ubuntu Boosts Developer Desktop Productivity | Ubuntu

    Seventeen years after its first release, Ubuntu is firmly established as the Linux developer desktop of choice around the world. From education through to enterprise, Ubuntu delivers the tools developers need to succeed across their careers. In this blog, we will cover the main aspects that contribute to this success. [...] Developers start their careers with Ubuntu, and 69% of student developers reported that they prefer Ubuntu as an OS. It’s not surprising. With Ubuntu, they gain access to the best of open source, including AI/ML frameworks, such as Pytorch and TensorFlow, ROS for robotics and LXD and multipass for virtualisation. Open source technology is now a critical part of any enterprise, and familiarity with open source is a key consideration in hiring. As a result, getting new developers onboarded and productive quickly is easier with Ubuntu. It’s a system they’re familiar with. It’s flexible and customisable. And, as an operating system, it spans both the workstation and the cloud, providing a consistent development experience across your technology stack.

  • Personal computer maker Raspberry Pi plans London listing

    The company behind Britain's best-selling personal computer is preparing the ground for a spring listing which is expected to value it at more than £370m.

    The trading arm of the Raspberry Pi Foundation has hired bankers from Stifel and Liberum to advise on a London float after securing a $45m (£33m) investment in September.

    The Cambridge-based foundation offloaded stakes to Lansdowne Partners and the Ezrah Charitable Trust to fund product development and marketing after seeing booming demand for its miniature personal computers during lockdown.

  • Mozilla Privacy Blog: Mozilla files comments on UK Data Protection Consultation

    Mozilla recently submitted its comments to a public consultation on reforming the UK’s data protection regime launched by the UK Department for Digital, Culture, Media & Sport. With the public consultation, titled ‘Data: A New Direction’, the UK government set out to re-evaluate the UK’s approach to data protection after no longer being bound by the bloc’s General Data Protection Regulation (GDPR). We took this opportunity to share our thoughts on data stewardship and the role effective regulation can play in addressing the lopsided power dynamics between large data collectors and users. For Mozilla, privacy is not optional. It is an integral aspect of our Manifesto, which states that individuals’ security and privacy on the internet are fundamental and must not be treated as optional. This is why privacy is at the core of our product work and why we have long promoted robust data protection in our policy and advocacy work. Further, Mozilla’s Data Futures Lab is exploring alternative approaches to data governance and promoting data stewardship through original research and support to builders.

  • 42 things I learned from building a production database

    In 2017, I went to Facebook on a sabbatical from my faculty position at Yale. I created a team to build a storage system called Delos at the bottom of the Facebook stack (think of it as Facebook’s version of Chubby). We hit production with a 3-person team in less than a year; and subsequently scaled the team to 30+ engineers spanning multiple sub-teams. In the four years that I led the team (until Spring 2021), we did not experience a single severe outage (nothing higher than a SEV3). The Delos design is well-documented in two academic papers (in OSDI 2020 and SOSP 2021). Delos is currently replacing all uses of ZooKeeper at Facebook.

    Here are some of the things I learned as the tech lead for Delos. My intent in publishing this is to help others in similar roles (leading teams that are building new infra at large companies); much of it may not generalize to different settings.
