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.

  • Mesa 18.1-RC1 Released With The Latest Open-Source 3D Driver Features

    Seemingly flying under our radar is that Mesa 18.1 has already been branched and the first release candidate issued.

    While the Mesa website hasn't yet been updated for the 18.1 details, Dylan Baker appears to be the release manager for the 18.1 series -- the second quarter of 2018 release stream.

Exploring Contributors Centrality Over Time

Filed under
Development
KDE

At the end of my previous post we concluded with yet another question. Indeed, on the 2017 KDEPIM contributor network we found out that Christian Mollekopf while being a very consistent committer didn't appear as centrality as we would expect. Yet from the topology he seemed to act as a bridge between the core contributors and contributors with a very low centrality. This time we'll try to look into this and figure out what might be going on.

My first attempt at this was to try to look into the contributor network on a different time period and see how it goes. If we take two snapshots of the network for the two semesters of 2017, how would it look? Well, easy to do with my current scripts so let's see!

What is Open Source Programming? How to Get Involved?

Filed under
Development

Open Source Programming simply means writing codes that other people can freely use as well as modify. It is essential for authors to license their code, it enables them to have a copyright for those codes. Therefore, for a code to be declared safe and free for all to use, whether it’s available in the Github or in a public-repo; the author is required to license their own code. This is to avoid cases of individuals being sued by the author for using, modifying or even embedding the code without being granted a license to do that.

Progress on Plasma Wayland for 5.13

Filed under
KDE

In February after Plasma 5.12 was released we held a meeting on how we want to improve Wayland support in Plasma 5.13. Since its beta is now less than one month away it is time for a status report on what has been achieved and what we still plan to work on.

Also today started a week-long Plasma Sprint in Berlin, what will hopefully accelerate the Wayland work for 5.13. So in order to kick-start the sprint this is a good opportunity to sum up where we stand now.

First set of Bionic (sort-of) RC images for 18.04.

Filed under
Ubuntu

Adam Conrad of the Ubuntu Release Team is pleased to announce the first
set of Bionic RC images for Ubuntu 18.04 LTS.

Over the next couple of hours, builds for Bionic Final should be added
to the tracker[1] for all flavours. The builds have some intentional
omissions, but please do test them anyway.

Known issues that will be addressed Sunday/Monday:
– Volume label still set to Beta
– base-files still not the final version
– kernel will have (at least) one more revision

Despite the above, please, please, please test your images. Do not
wait for a “final” build to test, as that guarantees your final build
will be broken. We need you testing now, iterating uploads to get
your bugs fixed, filing bugs and escalating where you need help.

Again: DO NOT DELAY, TEST NOW, FIX BUGS, FILE BUGS, ESCALATE FOR HELP.

Happy testing everyone, and here’s hoping we push out another smooth
and stress-free release on Thursday.

  • DataworksSummit Berlin - Wednesday morning

    Data strategy - cloud strategy - business strategy: Aligning the three was one of the main themes (initially put forward in his opening keynote by CTO of Hortonworks Scott Gnau) thoughout this weeks Dataworks Summit Berlin kindly organised and hosted by Hortonworks. The event was attended by over 1000 attendees joining from 51 countries.

    The inspiration hat was put forward in the first keynote by Scott was to take a closer look at the data lifecycle - including the fact that a lot of data is being created (and made available) outside the control of those using it: Smart farming users are using a combination of weather data, information on soil conditions gathered through sensors out in the field in order to inform daily decisions. Manufacturing is moving towards closer monitoring of production lines to spot inefficiencies. Cities are starting to deploy systems that allow for better integration of public services. UX is being optimized through extensive automation.

10 Great Linux GTK Themes For 2018

Filed under
GNOME

Customization is a big part of the Linux experience, and your desktop theme is no exception. The world of Linux desktop themes is an ever-evolving one, with new ones replacing old favorites all the time. Of course, the desktop environments and GTK itself are always changing, so that adds another dynamic element to consider. That said, some of the best desktop customization happens on the simplest desktop environments, like XFCE.

As of now, in early 2018, there are some really excellent GTK themes available. These themes aren’t ranked in any particular order. That comes down to a matter or preference. Any one of them can add a whole new look to your GTK-based desktop.

Ubuntu “Testing Weeks”

Filed under
Ubuntu
  • Ubuntu To Discontinue Opt-In Development Milestones In Favor Of Test Weeks

    The proposal for replacing early Ubuntu derivatives' early alpha/beta releases with "testing weeks" in its place is moving forward with no objections having been raised but flavors like Kubuntu and Xubuntu being in favor of the change.

  • Ubuntu Linux Replaces Alpha/Beta Release Model With “Testing Weeks”
  • Re-evaluating Ubuntu's Milestones

    Happy Release Week!

    I do not believe there have been any -1s to this proposal from any
    flavor, nor from the Release Team, so I think it's time to move forward
    with it.

    In summary, what will now happen from here on out is that opt-in
    milestones will be discontinued in favor of testing "weeks" (Tuesday
    through Thursday). I can organize the testing weeks for the 18.10 cycle
    (so we can get a process going), but from the 19.04 cycle and on,
    representatives (probably Release Managers) from any active flavor can
    (and should!) organize these testing weeks.

    Additionally, I will look into the automated testing Steve brought up
    shortly after the 18.04 release, with the goal being to adopt that
    sooner rather than later. I'll write a follow-up email to ubuntu-release
    once I have something to show for that.

    Thanks everyone!

Qt/KDE: Qt5 in Debian and Slackware, QtCreator on Android, KDE Discover, and Plasma's 10th Anniversary

Filed under
KDE
  • moving Qt 4 from Debian testing (aka Buster): some statistics, update II

    We started filing bugs around September 9. That means roughly 32 weeks which gives us around 5.65 packages fixed per week, aka 0.85 packages per day. Obviously not as good as we started (remaining bugs tend to be more complicated), but still quite good.

  • [Slackware] Plasma5 – April 18 edition for Slackware

    The KDE-5_18.04 release of ‘ktown‘ for Slackware-current offers the latest KDE Frameworks (5.45.0), Plasma (5.12.4) and Applications (18.04.0). The Qt5 was upgraded to 5.9.5. Read the README file for more details and for installation/upgrade instructions. Enjoy the latest Plasma 5 desktop environment.

  • Perfect Debugging Experience with QtCreator on Android

    While I was working on a yet-to-be-announced super secret and cool Qt on Android project, I had to do a lot of debugging. This way I found that debugging Qt apps on Android using QtCreator was ok, but it had some issues, which was kinda frustrating.

  • Discover – Easily Install Software on KDE Neon Desktop

    KDE Discover is an Open Source GUI app installer that comes packaged with KDE Neon. It was particularly built from the ground up to be compatible with other modern Linux distros with emphasis on beauty and convenience.

    KDE Discover was also designed to allow for an intuitive User Experience as it features a clean and clear layout with a high readability value which makes it easy to browse, search for, install, and uninstall applications.

  • Almost 10 years of Plasma-Desktop

    Last week I was at work and start to listen my boss said: “We need to show this to our director”. So I went to my coworker table to see what was happening. So they were using Gource to make a video about the git history of the project. Gource is a software version control visualization tool. So that triggered in my mind some memories about a friend talking about Python and showing how the project as grow in this past years, but I never discovered about the tool that made that amazing video.

    So well, I started to make some Gource videos, and because my love about KDE Community, why not make one about it?

  • The Infamous GNOME Shell Memory Leak

    at this point, I think it’s safe to assume that many of you already heard of a memory leak that was plaguing GNOME Shell. Well, as of yesterday, the two GitLab’s MRs that help fixing that issue were merged, and will be available in the next GNOME version. The fixes are being considered for backporting to GNOME 3.28 – after making sure they work as expected and don’t break your computer.

  • The Big GNOME Shell Memory Leak Has Been Plugged, Might Be Backported To 3.28

    The widely talked about "GNOME Shell memory leak" causing excessive memory usage after a while with recent versions of GNOME has now been fully corrected. The changes are currently staged in Git for what will become GNOME 3.30 but might also be backported to 3.28.

    Well known GNOME developer Georges Stavracas has provided an update on the matter and confirmed that the issue stems from GJS - the GNOME JavaScript component - with the garbage collection process not being fired off as it should.
