Nitrux is a Linux distribution based on Ubuntu suitable for laptops and desktop computers. Nitrux provides all the benefits of the Ubuntu operating system combined with a focus on portable, redistributable application formats like AppImages. Nitrux uses the LTS branch of Ubuntu as a basis using only the core system and then slowly building up to ensure a clean user experience. Nitrux is suitable for newcomers to Linux as well as *nix experienced users. Nitrux uses KDE Plasma 5 and KDE Applications; we also use our in-house software suite Nomad Desktop adding to the user experience. This sounds very similar to Elementary OS, but instead of Gnome and Gtk+-oriented, it’s built around Qt and KDE technologies. I like distributions that try to do something more interesting than being just another random Gnome or KDE distribution, and I especially like how the open source Linux community seems to be focusing more and more on polish, design, and simplicity lately. Very welcome additions to the Linux world.

Upribox 2.0 acts as a router and filters both trackers and ads, saving you the annoying task of manually hardening your web browser with countless add-ons.

Dangers lurk everywhere on the Internet. The technologies used by advertisers, criminals, and public authorities, not only to harass users but to spy on them, are becoming increasingly sophisticated. Protective mechanisms and countermeasures that make life difficult for data collectors and other curious users become all the more important.

Most users, though, do not have sufficient knowledge of the many dangers that lurk on the Internet and therefore take only partially effective countermeasures. Moreover, new technologies are increasingly complicating the configuration of web browsers, routers, and firewalls. In addition to in-depth knowledge, then, you also need a huge amount of time to secure an IT infrastructure.

Austrian security specialist Markus Donko-Huber already addressed this problem in 2014 at St. Pölten University of Applied Sciences and developed upribox (usable privacy box) with a small team. Upribox is a Raspberry Pi with a specially adapted version of Raspbian. The purpose of upribox is to ensure privacy and increased security when using the Internet, without requiring a great deal of configuration effort from the user.

How to Easily Remove Packages Installed From Source in Linux

In one of our previous articles, we’d shown you how to install and uninstall software in Linux outside the regular package managers. In that, we also saw that well-constructed software comes with built-in uninstallers. This way, you can remove the packages as easily as you install them.

Unfortunately, this isn’t always the case. There are plenty of packages out in the wild which don’t allow for clean removal. Sometimes you have no choice but to use a package like this because you need the functionality. However, there is a solution to the problem. In this article, we’ll show you how to use the software called “stow” to easily remove packages installed from in Linux.

Step 1: Install Stow

The “stow” package should be available in your regular package repositories. In this example, we are using CentOS so we need the extended EPEL libraries. You can install them using the command:

yum install epel-release

And after that, install stow like this:

yum install stow

Press yes to confirm the installation:

Now that stow is installed, we have to choose where to store our package files.

Step 2: Choose Where to Store Package Files

The normal “make install” command copies the package files into a variety of places. Stow works by keeping them all in one place in a single directory, and then creating symlinks to where they should have gone originally.

So we need to choose a directory for where stow keeps all the package files. By convention, this is usually:

/usr/local/stow/

And in this location, we have one single directory for each package. So if we want to install the “hello” program that we used as an example in the previous article, the files will be stored in:

/usr/local/stow/hello

But this location can be anything. Just to show, we’ll be storing the files in the following location:

/home/bhagwad/stow/

Step 3: Using “make install” with the “prefix” Option

We saw in the previous article that installing from source requires these commands:

./configure
make
make install

To install with stow, we just change the last step to:

make install prefix=/home/testuser/stow/hello

The “prefix” option tells us to place the packages in the given location. This location is nothing but the selected directory in Step 2 with the package name added on as a separate folder. This causes the files to be installed into the given location as shown here:

Now we have all the files required for the package in a folder in the stow directory. Time for the magic to happen!

Step 4: Completing the Installation with stow

To install the package, first “cd” into the stow directory like this:

cd /home/testuser/stow

Ensure that the folder with the files is just one directory below your current location. Now type:

stow hello

That’s it! The package is now installed on your system. Here’s a screenshot of the “hello” command working as intended:

But wait. The real benefit is yet to come. Uninstallation.

Step 5: Removing Packages

The coolest part about stow is how easy it is to remove packages from the system. No need to keep the source packages or anything. Just navigate to the stow directory as in Step 4 and type:

stow –delete hello

And it’s done! You can see below that the command no longer works after this step:

As far as the system is concerned, the package has been completely removed! It’s good to remember that the files haven’t actually vanished. They’re still in the “hello” directory. You could just as easily install the package again with the stow command. If you don’t require the files anymore, just delete the “hello” folder and your system is clean!

We recommend using stow every single time you install a package from source. It’s not worth the risk to have a badly written package spray your system with files everywhere, and which are a nuisance to remove afterward. Stow ensures that they’re all neatly contained in one location, then keeps track of the symlinks and deletes them afterward. It’s a fantastic solution!

Of course, if you are one of our Managed VPS hosting customers, you don’t have to remove packages installed from source, simply ask our admins, sit back and relax. Our admins will do this for you immediately.

Intel launched Intel System Studio 2019, updating the Linux-friendly embedded toolsuite with improved performance and enhanced I/O analysis. Meanwhile, due to soaring demand for Intel’s Core and Xeon sales, it’s scaling back its lower-end IoT business.

Intel has a habit of launching and the discontinuing special projects outside its core processor business, but one experiment that has stuck around is Intel System Studio. A lot has changed since we last checked on the Intel System Studio (ISS) development toolsuite when it launched in 2013. For example, while initially targeting both mobile and embedded software development for Linux and Android running on Intel processors, with the dissolution of Intel’s mobile business, it is now focused on optimizing embedded IoT applications running on its Atom, Core, and Xeon processors.

Intel System Studio 2019 architecture

Here we give the new 2019 version a look-see on ISS 2019, which is available in both a commercial version and a free, community-backed release. Our ISS update is followed by a report on Intel’s plans to scale back its embedded business.

Inside Intel System Studio 2019

The ISS toolsuite is designed to simplify “bring-up and improve system and IoT device application performance on Intel platforms,” says the company. The software includes platform-tuned libraries and compilers help optimize software, as well as domain-specific routines and system-wide visual performance analysis that can “quickly identify issues and reduce optimization time.”

Other features include debugging, tracing, and analyzing tools. ISS is now cross-platform, with support for Linux, Windows and Mac host desktops, as well as Linux, Windows, Android, VxWorks, and FreeBSD targets.

Intel announced the beta version of ISS 2019 back in June. However, it left it to InfoWorld to announce the final release on Oct. 30.

ISS 2019 adds a new workflow and simplified setup to one of the suite’s key components: Intel Vtune Amplifier. Vtune offers insights into CPU and GPU performance, threading performance and scalability, bandwidth, and caching. It supplies tools such as hotspots, call counts, annotated source code, and activity graphs.

The suite’s

Intel Advisor

software, which provides vectorization, threading, and optimization tools, features much improved performance and enhanced I/O analysis. It adds support for JIT profiling and “containers like Docker,” and makes various embedded platforms and accelerator improvements.

ISS 2019 provides an updated OpenCL framework that supports heterogeneous computing, says InfoWorld. The framework allows code to be offloaded to Intel processors and GPUs, making it easier to build, debug, and analyze OpenCL apps while also enabling customized kernel code with Intel computer vision and media software.

Finally, there’s a new Eclipse plug-in for Wind River Linux and its underlying Yocto Project code. The plug-in lets developers create or import application projects or platform projects for Yocto Project-compatible targets.

Interim Intel CEO Bob Swan

Intel to scale back embedded business

In other Intel news, the chipmaker solidly beat analyst expectations with its latest Q3 results. Due to shortages of its increasingly popular Intel Core and Xeon chips for the datacenter, Intel interim CEO and CFO Bob Swan told investors that Intel is prioritizing production for those product lines. According to a report in The Motley Fool, Swan went on to say that as a result of this prioritization, “by definition, the lower end of PC and the [Internet of Things] business is being constrained.”

Intel’s IoT Group (IoTG) comprised about 4.8 percent of Intel’s sales and grew 8 percent on a year-over-year basis last quarter. However, Intel projects that revenue will decline by 15 percent in the fourth quarter versus 3Q levels, with sales of around $781 million for a year-over-year decline of around 11 percent. That decline, however, also reflects Intel’s divestiture of Wind River, which had been part of IoTG.

If low-end Core and lower-end Gemini Lake chips fall into short supply, this would open an opportunity for AMD to grab market share in the IoT space. Yet, AMD also appears to be focusing on the high end with its popular Ryzen processors. AMD’s Ryzen Embedded V100 successor to the R-Series is off to a strong start in competing with high-end tom and lower-end, embedded focused Core chips, but the Intel rival has yet to release its much-delayed “Banded Kestrel” follow-on to the lower-end G-Series. This opens more opportunities for Arm vendors that can tolerate the narrower margins of the embedded chip business.

Former Intel CEO Brian Krzanich

Intel’s Swan took over as CEO a few months ago after former CEO Brian Krzanich resigned after admitting to violating company policy by having an affair with an Intel employee prior to becoming CEO. Swan was previously a CFO at eBay and then again at Intel, where he still holds the position.

Krzanich oversaw the strengthening of Intel’s datacenter chip sales, as well as its successful defense against Arm server chips. He also led Intel through the successful acquisition of FPGA maker Altera.

Yet, Krzanich also led the company’s failed mobile SoC experiment, as well as the discontinuation of the wearable Curie and embedded Joule modules. In addition, Intel has become more of a follower than a leader in the slow-motion march toward 10nm and 7nm chips. The resurgent AMD and a variety of Arm chip vendors are now leading the way.

Further information

Intel System Studio 2019 is available in a free community license backed by community forum support. You can renew the license every 90 days without limits. There are also a variety of paid license arrangements that give you greater access to Intel tech support. More information may be found on the Intel System Studio product page.

This step by step tutorial shows you how to type Indian Rupee Symbol on Ubuntu 18.04 with GNOME desktop. This procedure can also be applied to other desktop environments as well as other Linux distributions.

In 2010, the government of India unveiled the ₹ symbol for its currency, the Indian rupee. It has the unicode character U+20B9.

Over the time, the ₹ symbol started appearing on keyboards, both Indian and international. It is placed on the key 4 with US Dollar $.

Now typing $ is pretty straightforward. You use Shift+4 and you get $ symbol. But that’s not the case with ₹. It’s the third symbol on the key 4 and the question arises, how to type ₹?

To use the third symbol on any key (like the € on key 5), you have to use the AltGr (or the right Alt) key with the symboled key. So if you use right Alt+4, you should get the ₹ symbol.

But that doesn’t happen all the time. You have to do a few changes in order to type ₹ sign on Ubuntu.

Typing Indian Rupee Symbol (₹) on Ubuntu 18.04

Try Right Alt+4 key first and see if it works by default. If it doesn’t, you can follow the rest of the tutorial to get the ₹ support on your Ubuntu system.

Step 1: Adding the correct keyboard

In order to type ₹ on Ubuntu, you need to use the Indian English keyboard with Rupee.

No, I am not asking you to buy a brand new keyboard that has ₹ displayed on the key 4. I am suggesting to add this keyboard layout on your operating system. Let me show you how to do that.

Just so that you know, the same steps could be applied to other desktop environments like MATE, KDE Plasma etc. The screenshots won’t look the same though, so you would need to find your way through on your own.

In Ubuntu GNOME, press Windows key and search for Settings:

Go to Settings

In the Settings, look for Region & Languages and in here click on the + symbol under the Input Sources. This is the way to add a new keyboard layout.

Click on the three vertical dot symbol to display more keyboard layouts.

The search option may not work. So, you may have to scroll down and look for English (India). Click on it.

You would expect that it will add the English (India) keyboard immediately but that doesn’t happen. You’ll have plenty of keyboard options under English (India).

Look for English (India, with rupee). You can also search with rupee here. Once you have found this keyboard, click on Add button to add this layout.

Step 2: Change the keyboard layout

Now that you have added the English (India, with rupee) keyboard, it’s time to use it.

You can use the Windows + Space keyboard shortcut in Ubuntu 18.04. to change the input source i.e. to change the keyboard.

Use Windows + Space to change keyboard in use

If you are going to use the Rupee symbol all the time, you should make English (India, with rupee) the default keyboard. You can do that in the Settings by moving it up the order.

Move the keyboard up the order

Note: You may have to log out or reboot after changing the default keyboard so that these changes take into effect.

Step 3: Using keyboard shortcut to type ₹ on Ubuntu

Now that you have made sure that you are using English (India, with rupee) keyboard layout, use either of the following keys combinations to type ₹:

• If you have the AltGr key on your physical keyboard: AltGr+4
• Else, use the Alt key on the right hand side: Right Alt+4

This will type the ₹ symbol.

Note that you don’t need to have the ₹ symbol on the key 4 on your physical keyboard in order for this to work. It will work irrespective of whatever physical keyboard you are using.

I hope you were able to type rupee symbol after following this tutorial. If you have any questions or suggestions, please use the comment section below.
