Open Source Paradigms in R/U Development

As you probably know already, I am a Lecturer in the Urban Planning Faculty in Bucharest, so this new post shouldn’t come as a surprise. It is a short break from the usual posts, but it still has some connection with Linux and IoT, as you shell see.

It is my conviction that we live in a world of data and ideas. Besides nature, which is also based on data and which was slowly created on this planet since it’s inception, all other creations are basically data operations that lead to ideas being created and materialized. I am an architect and I believe that what the human kind ever creating is basically big chunks of data that was being modeled and interpreted.

Books you should read if you want to learn Linux

I know it has been a while since I wrote my last post, and I write my new one in time of celebration and joy. It is Easter and the mid-term holidays here in Romania, so I have a little bit more free time to read, and taking a look to my Kindle library I said that I should give you a hint on what books a Linux enthusiast should have on his/hers bookshelf.  Continue reading “Books you should read if you want to learn Linux”

Installing HPLIP in openSUSE Leap 42.2

If you own a HP printer or MFP, you will surely need the hplip drivers for it to work in Linux. Nevertheless, in openSUSE 42.2, you will come across several issues if you try to install it using the standard repos. Long story short, it won’t work at all if you would try to use your printer after installing hplip from the repositories using the zypper install hplip command.

Install multimedia codecs and True Type fonts in openSUSE

The openSUSE creators, being completely tributary to the open source philosophy, did not include multimedia codecs into the distribution. Thus, in order to listen to music or watch movies on your openSUSE system, you will need to install multimedia codecs from an external source. Continue reading “Install multimedia codecs and True Type fonts in openSUSE”

How to remove the Installation drive Path from the repositories list in openSUSE using CLI

I am pretty sure that, if you installed openSUSE distribution from a USB stick, you came along an unwanted error the very first time you try to update the system. This error is due to the fact that your USB drive containing the openSUSE installation files is listed amongst the system repositories. As the drive is no longer into the port, the update command will return an error. Continue reading “How to remove the Installation drive Path from the repositories list in openSUSE using CLI”

Basic Shell information

Each author chooses to present the commands and Linux operations in their own way. My personal opinion is that one needs to know at least basic information about the Shell in order to start working with Linux, thus I am presenting this basic tutorial in the very beginning of this openSUSE adventure. At first, you need to understand how Linux works and how commands are formed, what is the Shell and how is the file-system organized. After this, you will learn the basic commands you need to work with Linux and do very basic operations.

Take a look at what is written here, search for tutorials on the internet and maybe print out a small cheat sheet with the commands to use in vi/vim. This way you will exercise and remember the complicated way that vi/vim operates.

Additional support and resources

When it comes to Linux support, you can find lots of websites that are full of valuable information, but lately openSUSE lost a lot of ground in this area. Thus, some of the most important support websites remain the official community ones (there are many other Linux support websites, but ones related to openSUSE are not so many) . They are full of technical information adapted to different still supported openSUSE versions.

Why the choice of openSUSE and Ubuntu?

It’s all about Linux…

You may wonder why another website about Linux? Why openSUSE and Ubuntu? Both are well established Linux distros and have a large user-base and community. I like them both and use them on several systems. Here I will explain you why I choose to learn Linux by using these distros.
