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...

KDE: Akademy, BSD, Krita and Lays Rodrigues

  • 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.

Open-Source / Linux Letdowns For 2018

Filed under
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.

Dragora 3.0-beta1 released

I am pleased to announce the release of Dragora 3.0 Beta 1.

Dragora is a complete and reliable distribution of the GNU/Linux operating system that is entirely free software. Dragora is founded on the concepts of simplicity and elegance, it can be run for almost any purpose (desktop,
workstation, server, development, etc.). The intended audience is people
interested in learning more about the technical aspects of a friendly
GNU/Linux distribution.  Also people looking to use the purest ethical
software for daily use.

The beginning of the development of the series 3.0 represents the
migration towards a new C library, Musl.  The continuation of
supervision capabilities (introduced for the services in 2012).
The restructuring of the hierarchy of directories, the improvement of
the tools provided by the distribution, a new automatic method to build
the distribution, the prebuilt cross-compiler set, and much more!

The homepage is at www.dragora.org

Current development pages are located at
https://git.savannah.nongnu.org/cgit/dragora.git/ and
https://notabug.org/dragora/

Changes in this version:

  * A new installer for this series has been introduced, it can be
    invoked from the command line as `dragora-installer'.

  * A new tool (based on dialog(1)) has been introduced to
    configure the keyboard mapping in the console, it is called
    `dragora-keymap'.

  * Our simple and friendly package manager has reached version 1.3,
    which contains minor changes and fixes.  It is worth mentioning
    that Qi now uses `tarlz' to produce, list packages in parallel.
    Tarlz uses a simplified and safer variant of the POSIX pax format
    compressed with our favorite compressor "lzip".

  * To complement the security in general, for binaries with PIE and
SSP (both are default features in Dragora), they are now complemented
    with RELRO by default.

  * The main toolchain has been upgraded.  This -beta1 have Binutils
    2.33.1, The GNU C Compiler 9, GNU Linux libre 4.19.78, and
    Musl 1.1.24.

  * LibreSSL has been upgraded to the version 3.0.1

  * Ruby (programming language) version 2.6.5 has been introduced.

  * Support for FUSE (in the kernel) and user space, is now available
    in Dragora.

  * Xfce 4.14 has been introduced in this version.

  * dragora-ice, a customized version of IceWM has been added.

  * All the official X.Org components has been updated (drivers, server,
    applications, etc.).  Included new drivers: xf86-input-elographics,
    xf86-video-amdgpu, xf86-video-vboxvideo.  The configuration for the
    xf86-video-intel driver has been fixed this time.

  * Work to complete DocBook support in Dragora is underway.

  * Build recipes for new packages have been built:

    Please, traverse the /usr/pkg hierarchy for a full view of
    installed packages.

  * Many general fixes, improvements, and clean ups have been performed.

The ISO images may be fetched at:

    https://sourceforge.net/projects/dragora/files/beta/

See http://dragora.org/en/mirrors.html for a list of available mirrors.

Dragora is available in "live" or hybrid ISO image form. You need the .iso
for the packages if you want to perform a hard disk installation.

Notes:

* The password for the root user in the Live CD is: dragora

This beta version can be considered as stable, it is catalogued just as
beta because it lacks many things that we will try to complement in future
versions.

We welcome feedback at our Freenode IRC channel, #dragora, and on our
mailing list.  We are looking for help with documentation, testing,
bug reports, patches, etc.

Thank you to all of you who support this humble project made with great
sacrifice.  And thank you especially for supporting the philosophy and
spirit of software freedom that Dragora aims to promote.

Best regards,
Matias Fonzo, Dragora author and maintainer.
