  • When should you open source your software?

    It’s 20 years this this since the term ‘Open Source’ was coined. In that time the movement for free and open software has gone from a niche to a common method of distribution and a normal way of operating for businesses.

    Major technology shifts are now driven by open source technologies: Big Data (Hadoop, Spark), AI (TensorFlow, Caffe), and Containers (Docker, Kubernetes) are all open projects. Massive companies including Google, Facebook, and even Lyft regularly release Open Source tools for the world to use. Microsoft – whose former CEO once described Linux as a cancer – now embraces the concept.

  • GNU Parallel 20180422 ('Tiangong-1') released

    Quote of the month:

    Today I discovered GNU Parallel, and I don’t know what to do with all this spare time.

  • Devhelp news

    For more context, I started to contribute to Devhelp in 2015 to fix some annoying bugs (it’s an application that I use almost every day). Then I got hooked, I contributed more, became a co-maintainer last year, etc. Devhelp is a nice little project, I would like it to be better known and used more outside of GNOME development, for example for the Linux kernel now that they have a good API documentation infrastructure (it’s just a matter of generating *.devhelp2 index files alongside the HTML pages).

Why Everyone should know vim

Filed under
Software
HowTos

Vim is an improved version of Vi, a known text editor available by default in UNIX distributions. Another alternative for modal editors is Emacs but they’re so different that I kind of feel they serve different purposes. Both are great, regardless.

I don’t feel vim is necessarily a geeky kind of taste or not. Vim introduced modal editing to me and that has changed my life, really. If you have ever tried vim, you may have noticed you have to press “I” or “A” (lower case) to start writing (note: I’m aware there are more ways to start editing but the purpose is not to cover Vim’s functionalities.). The fun part starts once you realize you can associate Insert and Append commands to something. And then editing text is like thinking of what you want the computer to show on the computer instead of struggling where you at before writing. The same goes for other commands which are easily converted to mnemonics and this is what helped getting comfortable with Vim. Note that Emacs does not have this kind of keybindings but they do have a Vim-like mode - Evil (Extensive Vi Layer). More often than not, I just need to think of what I want to accomplish and type the first letters. Like Replace, Visual, Delete, and so on. It is a modal editor after all, meaning it has modes for everything. This is also what increases my productivity when writing files. I just think of my intentions and Vim does the things for me.

Software

While everyone knows that most Linux distributions (distros) are free to download, not everybody is aware that you also have access to thousands of cost-free applications through your operating system’s package manager.

Many of the more user-friendly distros will come with a selection of software preinstalled to help you get started, but there are many more apps out in the wild, under continuous development.

A look at KompoZer Web-editor in GNU/Linux

Filed under
Software

Some people code HTML/CSS oldskool in software like Atom, Notepadqq, or even nano/vi, but others enjoy using what’s called a WYSIWYG editor, which stands for What-You-See-Is-What-You-Get.

KompoZer, is a free cross-platform WYSIWYG editor worth looking at despite the fact that it has not been updated for a very long time. Note though that KompoZer lacks support for features like HTML5 or CSS3 that were introduced after the last version of the HTML editor was released.

As is the case with a lot, but not all, of software in GNU/Linux systems that people use, KompoZer is technically multi-platform, but I would say that the GNU/Linux and MacOS user share dominate the Windows one, from my experience.

Luckily, a developer has created this extension to enhance keyboard navigation in Google search. This plugin is free and open source. So, you can get the code freely on GitHub link provided at the end of this guide.

    As you read this post, keep in mind that my particular use case of notification on ssh login is not for everyone. It may not appeal to you. In fact, you might find this to be an absolutely ridiculous thing to do. I respect that. I suggest that somewhere within your network there is at least one type of error condition, one urgent situation, one thing that you would like pushed to your cellphone / pager / etc. It might be a failed HDD for example.

Red Hat
Software

COPR is a collection of personal repositories for software that isn’t carried in Fedora. Some software doesn’t conform to standards that allow easy packaging. Or it may not meet other Fedora standards, despite being free and open source. COPR can offer these projects outside the Fedora set of packages. Software in COPR isn’t supported by Fedora infrastructure or signed by the project. However, it can be a neat way to try new or experimental software.

Here’s a set of new and interesting projects in COPR.

  • Random Wallpaper Gnome Extension Changes Your Desktop Background With Images From Various Online Sources
    Random Wallpaper is an extension for Gnome Shell that can automatically fetch wallpapers from a multitude of online sources and set it as your desktop background. The automatic wallpaper changer comes with built-in support for downloading wallpapers from unsplash.com, desktopper.co, wallhaven.cc, as well as support for basic JSON APIs or files. The JSON support is in fact my favorite feature in Random Wallpaper. That's because thanks to it and the examples available on the Random Wallpaper GitHub Wiki, one can easily add Chromecast Images, NASA Picture of the day, Bing Picture of the day, and Google Earth View (Google Earth photos from a selection of around 1500 curated locations) as image sources.

  • Celebrating 10 Years with KDE
    Of course I am using KDE software much longer. My first Linux distribution, SuSE 6.2 (the precursor to openSUSE), came with KDE 1.1.1 and was already released 19 years ago. But this post is not celebrating the years I am using KDE software. Exactly ten years ago, dear Albert committed my first contribution to KDE. A simple patch for a problem that looked obvious to fix, but waiting for someone to actually do the work. Not really understanding the consequences, it marks the start of my journey within the amazing KDE community.
  • GSoC 2018 – Coding Period (May 28th to June 18th): First Evaluation and Progress with LVM VG
    I got some problems during the last weeks of Google Summer of Code which made me deal with some challenges. One of these challenges was caused by a HD physical problem. I haven’t made a backup of some work and had to rework again in some parts of my code. As I already knew how to proceed, it was faster than the first time. I had to understand how the device loading process is made in Calamares to load a preview of the new LVM VG during its creation in Partition Page. I need to list it as a new storage device in this page and deal with the revert process. I’ve implemented some basic fixes and tried to improve it.

Open Hardware: Good for Your Brand, Good for Your Bottom Line

Chip makers are starting to catch on to the advantages of open, however. SiFive has released an entirely open RISC-V development board. Its campaign on the Crowd Supply crowd-funding website very quickly raised more than $140,000 USD. The board itself is hailed as a game-changer in the world of hardware. Developments like these will ensure that it won't be long before the hardware equivalent of LEGO's bricks will soon be as open as the designs built using them. Read more
