XnViewMP is a Full-featured Image Manipulation and Batch Converter Tool

The quality of image and video capture has improved tremendously over the years and the capabilities of our digital devices continue to push the limits of image quality. However, there is a bummer! The high-res images we take does come at the hefty price of an increase in the size of images taken.

For this reason, uploading images on the internet can be painfully slow especially if you’re on a network with minimal bandwidth. While there are varying online services and softwares for other platforms that will effectively convert your image files while still maintaining the original quality, it is rather hard to come by native clients for Linux systems.

XnViewMP – Image Manipulation Tool

XnviewMP is a full featured cross-platform image manipulation software; albeit not in the league of GIMP and Photoshop, the software does own up to its advertised features and capabilities.

Asides being a batch image converter, XnViewMP supports a wide variety of formats totaling 500 including animated; it is bundled with a number of filters and effects, and quite a few other basics as listed below followed by the 500 formats supported – you can, however, jump straight to XnViewMP installation , if you’d rather not go through the list.

Other noteworthy features of XnView’s Linux client include:
  • 70 graphic export file formats supported
  • Support for multipage TIFF, Animated GIF, Animated ICO
  • Image IPTC, EXIF metadata support
  • EXIF auto rotation support
  • IPTC editing
  • Support for resize, rotate, crop
  • Brightness and contrast adjustment supported
  • Fullscreen mode
  • Image slide show with effects
  • Screen capture
  • Create or edit Multi-page file (TIFF, DCX, LDF)
  • Multi-language
  • Compare image side by side
  • Filmstrip layout
And the long list of supported input formats (alphabetically) are:
  • ADEX img,rle
  • AIM Grey Scale ima,im
  • ARF arf
  • AT&T Group 4 att
  • Access g4
  • Aces200 ace

  viDrop – A Simple and Straightforward Video Converter for Linux

Installing XnviewMP in Linux

Note: Instruction is particular to DebianUbuntu, and derivative systems.

You can download the XnviewMP precompiled debs (available for both x86 and x64 architectures) or compressed tgz file (for other systems) from here.  Alternatively, you can download the application from  Getdeb.net which is an unofficial repository for Ubuntu packages.

Before downloading the package from Getdeb.net, you’ll need to install Getdeb itself and you can find instructions here  after which you’ll then search for XnviewMP on Getdeb or download directly here – but only after you might have setup Getdeb on your PC.

xnviewmp startup wizard

xnviewmp interface

xnviewmp batch converter

XnviewMP is overall great and surprisingly robust; however, the application is proprietary but free and doesn’t come with adware or bloatware.

Alternatively, if you prefer minimalistic, we recommend Trimage or XnConvert (a stripped down version XnViewMP) both of which are also quite the functional batch image converters without the bells and whistles XnviewMP ships with, of course.

Watch the Meizu Pro 5 Ubuntu Phone Get Unboxed

The Meizu Pro 5 has been making its rounds on the internet despite the almost impossible means of getting the device. Given the smartphone runs Ubuntu Touch, we can’t but give into what happens to be the most powerful Ubuntu smartphone yet.

Previously, we covered the availability of the device which was set at a rather disappointing price of $370 as though it’s limited availability wasn’t bad enough (exclusiveness to JD.com ) – this, ofcourse, has turned many potential buyers away.

The Meizu Pro 5 remains an interesting device despite its quirks and lack of foresight of the manufacturing company. The Pro 5 is available in two variants – one running Ubuntu and the other which I’d assume you already know runs Android.

So in the case of this device, you can potentially decide to run Android on it or heck, get one running Android and slap Ubuntu Touch on it.

meizu pro 5 exterior

meizu pro 5 white

In essense, since the Ubuntu version is proving too hard to get, you can as well go for the Android-powered model and flash some Ubuntu goodness on it.

Just a remainder, or incase you never knew, the Pro 5 is an all metallic beauty powered by an Exynos 7420 made by Samsung and based on a 14nm process in a big.LITTLE configuration with a peak frequency of 2.2Ghz.

  The Next OTA For Ubuntu Touch Will Change Libertine Scope to Desktop Apps

The device featured an FHD IPS display at 1920 by 1080 Pixel at 441 PPI with Corning Gorilla Glass 4 covering the panel. Other configurations worth a mention is it’s 4GB LPDDR4 RAM, an internal storage of 32GB, USB Type C with color variations of gold and silver – however, you can only get the gold version on the JD store otherwise Joybuy at the moment.

Despite the uninteresting facts associated with Meizu’s flagship Ubuntu Touch-powered smartphone, it’s an incredible device and achievement for the Linux space.

if you care to see the device in its glory, you may watch the unboxing video below. Be sure to leave your feedback in the comments at the end of this page and as usual, keep it tuned to Tecmint.

Meet A New Generation of Portable Linux Apps for Ubuntu 16.04

Are you tired of the hustle of having to install your favorite apps in Ubuntu, then worry no more, OrbitalApps brings you a new generation of portable Linux applications for free. All the portable apps are in compressed .ORB (Open Runnable Bundle) file format and are meant for Ubuntu 16.04 LTS Xenial Xerus.

Some of the supported apps include among others: Mozilla Firefox, LibreOffice, VLC Media Player Thunderbird, GIMP, Kodi, ISO Master, Audacious, FileZilla plus many more.

You can view a full list of all the portable apps from here but in this overview, we shall look at the features of these apps, how they actually work and how to use them.

Features of ORB(Open Runable Bundle) Apps

The .orb format apps have the following features:

  • no need to be root to run apps
  • simple, open by clicking and use
  • they start in seconds
  • they are compressed, therefore small in size
  • portable
  • open source
  • cryptographically signed with these security features

How the .orb apps work

There is no need to install any app, when you run an app from a folder or USB stick, it will automatically get in to the “Portable” mode, and this means that all the app settings are stored within the folder or USB stick you have the apps on.

  LabXNow – Code, Develop, and Test Software From Anywhere on the Cloud

How to use the apps

The apps are launched from within the ORB Launcher app which you can download from OrbitalApps website , so you need to install it before you can start using the apps. There are many ways to install the ORB Launcher app and they include:

1. Download the ISO installer

Move to the download folder and right click on the ORB launcher file, open it with Disk Image Mounter.

ORB ISO Launcher File

Then move to the mounted folder and open autorun.sh and Click Run in Terminal or Run. In this guide, I used Run in Terminal to install the ORB Launcher app.

ORB ISO Mounted Folder

Options To Run Autorun.sh File

Before the actual installation, you will be prompted for your user password, enter it and authenticate.

Enter User Password

Wait until you see the message below, showing successful installation.

2. Automatic Installation

Open a terminal, and then run one of the commands below:

curl http://www.orbital-apps.com/orb.sh | bash


wget -O – https://www.orbital-apps.com/orb.sh | bash

3. .deb installer

Download the ORB Launcher app as a .deb file and install it as follows:

sudo dpkg  -i ~/path/to/file/orb-launcher_0.1.047.deb

After successfully installation of ORB Launcher app, you need to reboot your system for the changes to take effect.

When that is done, you are good to go, simply download any supported portable app from here , and use it. For example download portable versions of blender, mozilla firefox and vlc media player as shown in the screen shots below:

Download Portable Blender App

Download Portable Mozilla Firefox App

Download Portable VLC App

Here is my folder containing all the portable apps I have downloaded, to use any app, i can simply open it using ORB Launcher app.

Download Portable VLC App

You can also download and use superdebs on your Ubuntu 16.04 system. Easy and simple, although these apps are only designed for Ubuntu 16.04, you can use them on the latest versions other distros such as Debian and Linux Mint though not guaranteed.

The use case of the portable apps will be mostly particular to the individual using it. Have you tried it it before? If yes, in what situations do you use it? Let us know in the comments below.

Trimage – A Lossless PNG and JPG Compressor Tool For Linux

If you work with websites regularly or if you’re a writer like me and you often have to post images on the internet, then you’ll realize the importance of using lightweight images as they are generally faster to upload and are also good for search engine optimization and regular folks that take bandwidth conservation into serious consideration.

Trimage is an open-source lossless batch image converter tool that is cross-platform, GUI and command line-based, with a focus on PNG and JPG file types.

Trimage was originally inspired by  imageoptim  for OSX systems and has mainly focused on flexibility and ease of use.

From their website,

Trimage gives you various input functions to fit your own workflow: A regular file dialog, dragging and dropping and various command line options”.

Trimage’s simplistic interface will easily win you over if all you’ll basically need to do most of the time is converting PNGs and JPEGs without any extra features.

The extensive command line options available to it will also please those developers that spend most of their time in the Unix shell. If you, however, need more functionality for your image conversions together with more supported formats, then XnViewMP is potentially the way to go as the application is not only a batch image converter but a manipulator and a whole lot more.

trimage image compressor

trimage compressing

Below are some basic command line options as seen on its website; so just in case you’re looking to use the application via the command line interface.

  • --version – display program’s version number and exit
  • -h, --help – display help message and exit
  • -v, --verbose – Verbose mode (default)
  • -q, --quiet – Quiet mode
  • -f FILENAME, --file=FILENAME – compresses image and exit
  • -d DIRECTORY, --directory=DIRECTORY – compresses images in directory and exit
  10 Best Live Chat Software Solutions in (2019)

Installing Trimage in Linux

If you’re on Debian, Ubuntu and derivatives, you can easily download it from the standard repositories using the good CLI.

$ sudo apt install trimage

For Arch Users

you can find Trimage in the AUR.

# yaourt -S trimage-git

Other systems will need to visit the official website to find instructions as per your operating system and you can also visit their GitHub to find more related info if you care to.

Slurm Architecture

The Slurm system is based on a centralized manager, slurmctld which monitors different resources and work, and it may include a backup manager responsible for protecting system state in case of any failure.
Each host on the cluster has a slurmd daemon which is compared to a remote shell and receives work, executes it, returns status and then waits for more work to execute, the daemon also enables fault-tolerant communication in the system setup hierarchy. There is also an optional slurmdbd(slurm database daemon) used to record accounting information from several Slurm-managed clusters in a single database. You can read about the complete architecture from here .

Discord – A Cross-Platform VoIP Service For Gaming Enthusiasts

VoIP apps are potentially in their hundreds out there and there are millions of users around the world using these services for various purposes ranging from conference calls to business meetings and basic chat amongst friends and family.

Skype thrives on the desktop platforms and has the upper hands in terms of the user base as it boasts an average of 80 million users online at any particular time of the day.

Skype is, however, no longer the same ever since its management was handed over to Microsoft back in 2011 – with the fact that it’s now meant to solely profit the Redmond-based company’s business model in every possible way. Irrespective, it remains one of the most used VoIP applications that aims to cater for just about every need and also falls short in so many aspects.

While we’ve covered four VoIP alternatives to the Skype IM (which include  Ring , VopTop, Tox, and Retroshare ) in recent weeks, there’s was no mention of one dedicated to gamers.

You may argue that basic screen sharing feature that accompanies some of the aforementioned programs will allow you enjoy a  gameplay with another gamer over the internet, – it can’t and won’t be as effective as a program that is built especially for the particular purpose of interaction while gaming.

Discover Discord, a gamer-centric VoIP application built by a passionate team of enthusiasts for other gaming fanatics around the world. Clearly from the comparison table below, you can see the list of features that makes the application stand out from the competition.

discord features in comparison with the competition

Discord is a proprietary application that is offering its core functionality at absolutely no cost which brings up the question of how they intend to incur revenue; apparently, it’s made evident on their  website that “..there will be optional cosmetics like themes, sticker packs, and sound packs available for purchase”.

Also, the Discord team made quite a point with this statement , “We think it’s time to ditch Skype and Teamspeak. Two hundred seventy million PC gamers use these apps to communicate while playing online games yet they haven’t been updated in years and no longer meet our needs”.

Discord, having been around for only a year has garnered quite an impressive number of users who are delighted with the service – and the long list of benefits it brings to the table – as evident on their Twitter page .

The application in its current state has both voice and text chat while still cross-platform with support for Windows, OSX, Android, and iOS.

Video support is planned in the nearer future and you can currently download the Linux client  Discord Canary – (which is still in development) after which you’ll automatically sign up as a beta tester when you log into the app on your Linux system but only after you might have created an account on their web page .

Aethercast Arrives on The Nexus 5, OnePlus One Support in Tow

Ubuntu’s convergence has made some serious strides in the past few days – having been made available with the OTA 11 software update on the original Ubuntu Touch powered Meizu Pro 5 via Aethercast i.e wirelessly, it is making its rounds boastfully to other smartphones powered by the open source mobile operating system.

We are getting it as fresh news that the aforementioned Convergence technology will be making its way to the OnePlus One and the Nexus 5 thanks to UBport’s developer Marius Gripsgård for making it known to us via his Google Plus post .

The recent OTA-11 update brought about the Aethercast for wireless Convergence to the Meizu Pro 5 while leaving the older Ubuntu Touch smartphones behind. But worry not, the update will equally be pushed out to other devices running Ubuntu Touch officially in the nearer future.

It is, however, worth noting that the performance of Convergence is expected to suffer terribly on these older devices which includes the Bq Aquaris, and Meizu MX4 as they don’t pack as much punch as the Meizu Pro 5.

Disregarding the odds, we hopefully will still be able to do the most basic stuffs like running a web browser with a few tabs opened, creating docs and using an email client.

Anything other than that like running GIMP and any other power hungry application would definitely be asking too much from the the smartphone’s hardware.

Convergence via Aethercast on OnePlus One and Nexus 5

The OP1 and Nexus 5 are some of the devices receiving unofficial support from the UBports group and Marius is apparently working hard to bring this to fruition on the above-mentioned smartphones.

Quoting Gripsgård, “This build is based on the ubp-5.1 branch (android 5.1/cm12.1), and build is released on the ubports unstable channel “devel_rc-proposed” and will be released on the main channels once it’s stable”.

Nexus 5 Aethercast

Currently, the build for the Nexus 5 can be downloaded and tested while that of the OP1 is underway (ready sometime next week). If you’re feeling adventurous, you can go on ahead and downlad the respective image for you device and switch to the unstable branch by entering this link ( http://system-image.ubports.com/ ) on your smartphone so as to help report and fix bugs.

Furthermore, Marius urges those of you that own a Microsoft Wireless Display Adapter to test the Aethercast feature using this app on the Google Play Store  on your Android device.

Download Android APKs on Your Linux System With Google Play Downloader

Google’s Play Store is by far the largest repository of Android apps and the applications featured on the mobile store is unmatched by other alternative app stores for Android.

According to Statistics , the Play Store (formerly Android Market) boasts of an approximate 2million applications thereby trumping the Apple iOS store by over half a million apps.

This takeover was very much expected as the adoption of Android has always been fast paced ever since its inception way back in 2008 particularly because of its openly extensible nature and the Linux Kernel.

Google being the sole architect of the operating system means that its bundled services are ever present on a whopping 90 percent of devices running the open-source operating system.

The control Google exerts on Android has given it an upper hand as the sole distributor of the software to the extent where Android itself is seemingly meaningless without Google’s proprietary services bundled with it.

Google Play Downloader

While the services the search giant offers are mostly free and extremely useful, it does come at the hidden and somewhat hefty price of sacrificing your data to the hands of the conglomerate to better help it throw targeted ads in your face which is what its core business revolves around.

This is not entirely as bad as it may sound; but in the case you’re paranoid and completely want to rid your Android smartphone of Google, it would perhaps gladden you to know that you can get just about any free application on the Play Store with this open-source Google Play Downloader application on Linux.

Google Play Downloader saves APKs directly to your Linux PC

This application became available due to a concern the developer (Tuxicoman) had about privacy as elaborated in this statement, ” …wanted to get applications from the Google Play store but didn’t like my Android AOSP system being tainted by Google root services neither being filed in the Google account database”.

The application has been in active development since its inception way back in 2013 with the latest version at 1.8. Google Play Downloader as is so-called is not affiliated with Google in any way is independently developed by Tuxicoman.

Google Play Downloader is written in Python, licenced under the GNU Affero General Public License and based on existing projects (as seen below) that allow it to seamlessly connect to the Google Play services.

  • GooglePlay-api to interact with Google PlayStore (https://github.com/egirault/googleplay-api/) BSD license
  • Androguard to read info info from local APKs on disk (http://code.google.com/p/androguard/) LGPL license
  • Android-checkin-1.0.jar to create AndroiID from Google credentials. (https://github.com/nviennot/android-checkin/) MIT license

The application is apparently platform independent (as seen on the developer’s page ) and has precompiled debs for Debian, Ubuntu and derivatives. It is also available in the AUR for Arch Linux users while for other systems, you may compile from source .

Desktop Independent Apps Vs Desktop Dependent Apps in Linux?

Early this year, many Linux Mint users learnt about the fact that the Ubuntu Linux based distro was going to introduce its own set of apps called X-apps in Linux Mint 18, and this has been true so far, when you read more about the new features of the beta release of Linux Mint 18 Cinnamon.

What are X-apps?

It is a new project started with the aim of producing generic apps for traditional GTK desktop environments such as Cinnamon, MATE, Xcfe plus the rest.
It is intended to develop core apps that will fuse well with the above mentioned desktop environments and do away with apps that do not integrate well outside of these desktop environments. Therefore, when changes or new features are added to an app, it will apply to all the desktop environments.

The main features of X-apps

  • use modern toolkits and latest technologies
  • are generic meaning they work everywhere
  • use traditional user interfaces
  • are backward-compatible
  • provide existing functionalities

Most of the apps simply offer existing functionalities, therefore users do not need to worry about having to learn anything new to use them.

What actually works better: Desktop Dependant Apps Vs Desktop Independent Apps

Having given you a fair highlight of the X-apps project, you will realize that these apps are desktop environment dependent, working and integrating properly with the traditional GTK desktop environments that we mentioned above.
On the other hand, is the desktop environment independent apps such as Thunderbird, LibreOffice and VLC which can work on most if not all desktop environments including KDE, GNOME, and it is also a cross-platform software, and works on major operating systems such as Windows and Mac OSX plus many more.
One fact about these apps is that their development is not focused towards any platform or desktop environment, they simply work everywhere but the question is whether they can fit anywhere in terms of proper integration with a desktop.

  How to Install Mate Desktop 1.24 on Ubuntu 20.04

You can actually look at the above argument in two possible ideas:

    • First, developing specific apps for each desktop environment or a group of desktops

Here, desktop environments would have small apps offering basic features and functionalities to users, integrating well with the user interface. And you will realize that the Linux Mint X-apps actually fall under this description.

    • Secondly, developing core apps with different user interfaces to fit in each desktop environment

Under this, developers would have to tailor user interface for each desktop environment but maintaining and offering multiple, core cross-platform functionalities.

As a concluding remark, i think it is advantageous to consider and maintain both ideas here, desktop environments need to have their own apps that users can easily adapt to, and developing desktop environment independent apps is vital to offer users a wide range of apps that they may find extensively productive and offer advanced features and functionalities.
This is an important argument as the existence of several Linux distributions and desktop environments is always a big challenge for new Linux users in terms of which one to choose and stick with. What is you take on this issue? You can share your thoughts via the comment section below.
