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.

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.

OSS and Openwashing Leftovers

  • Why retail marketers must get CX right the first time and how open source plays a key role

    One of the great things about technology is that it has raised all of our expectations. Once upon a time, people worried that controlling their television with a remote would make them lazy. Now, we don't even have to find the remote. We just talk to the TV — literally. We access hundreds of goods and services easily, without leaving the comfort of our chairs: we download games, order the supermarket shop, watch films and read books online. It really is a brave new world. But with new worlds come new challenges, and the challenge of the new, tech-driven, marketplace is to make your business stand out in a global crowd. Of all the businesses in all the world, why should your customers choose (and stick with) you? Lots of people will tell you that the key to gaining market share lies in improving the customer experience. And they'll be right. A combination of the need to impress and increased customer expectations have combined to make CX fundamental to gaining and retaining custom.

  • The Future of Great Customer Experience Relies on Open Source

    A majority of U.S. consumers feel that brands don't meet their expectations. The bar for customer experience has been set high -- and its on marketers to reach it. [...] In the early 2000s, enterprise IT was dominated by proprietary software companies. Now, with the rise of public cloud computing, more and more developers are adopting open source tools within their organizations due to lower overall costs and access to the latest innovations. The adoption is spreading from IT into other sectors of the business as well, notably marketing. In total, marketing and experience cloud vendors invested over $8 billion to acquire open source companies in 2018, according to PitchBook.

  • How spicy should a jalapeno be?

    Everyone has opinions and preferences, especially when it comes to food. To establish a criterion when answering "How spicy should a jalapeño be?." the Scoville Heat Scale was developed as a standard to measure spiciness. This scale allows people to communicate and share information about how spicy we like our peppers. Similarly, open source technology standards, such as USB, I2C, MQTT, and others, were developed to enable global compatibility. Furthermore, open source hardware platforms have enabled communities to “speak the same language” without reinventing the wheel. For example, Raspberry Pi makes it easy for people to use their hardware as a baseline and then add onto it. This has created a revolution in many industries by enabling individuals, startups, and large corporations to apply hardware and software to complex problems without having to design them from the ground up.

Linux 5.4 Adds Support For The FlySky FS-iA6B - A Receiver Popular With DIY Drones

The input driver updates for the Linux 5.4 kernel include the addition of an interesting, budget-friendly RC receiver that can be used for home-built drones and other use-cases while now the driver allows the receiver when paired with a supported RC controller to serve as a traditional Linux joystick input. The input updates were sent in earlier this week and among the changes are allowing drivers to support more precise timestamps for better velocity tracking, improvements to the BU21013 touchpad driver, and other changes as outlined in the pull request.

GNOME: Wayland With MATE, NetworkManager and Sébastien Wilmet

  • Ubuntu/Mir Developer Issues Porting Guide To Help Port MATE To Wayland

    Canonical's Mir developers since re-shifting focus to serving as a Wayland compositor have been working with the likes of the GNOME2-forked MATE desktop environment to implement Wayland support using Mir. For helping those interested in porting MATE applications from X11 to Wayland, one of the Mir developers has now issued a porting guide.

  • NetworkManager Will Now Roam For WiFi Signals More Aggressively

    NetworkManager has shifted its threshold for a weak WiFi signal for when to begin searching for other WLAN networks. Up to now NetworkManager used a -80dBm threshold for when to roam for other network signals while now that has changed to find hopefully stronger network signals sooner. 

  • Sébastien Wilmet: Back to University

    And to avoid stress/burnout, I try to no longer work the evenings and weekends, so it drastically limits my time that I’ll devote to GNOME.
