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.

  • Pakistan Open Source Summit 2018 concludes [Ed: Not about software]

    A large number of attendees from industry, academia, government, and students participated in the summit. Portuguese Ambassador to Pakistan Dr Joao Sabido Costa was the chief guest at the opening ceremony while former Naval Chief Admiral (r) Asif Sandila graced the occasion as the chief guest at the closing ceremony.

  • ‘Open Summit key to create industry-academy linkages’

    Ambassador of Portugal to Pakistan Dr Joao Sabido Costa has said that events such as the Open Source Summit are excellent for spreading awareness and for creating industry-academia linkages and enhancement of the information technology.

    He stated this while addressing a concluding ceremony of the two-day informative ‘Pakistan Open Source Summit 2018’ attended by large number of people from industry, academia, government and students. Former naval chief Admiral (R) Asif Sandila co-chaired the concluding session.

    Dr Joao Sabido Costa said that the organisations should utilise open source platforms to build their IT infrastructures in future. To build open source culture in Pakistan, he recommended roadmap with future activities and timelines for spreading open source.

  • Madrid GNOME+Rust Hackfest, part 2

    Yesterday we went to the Madrid Rust Meetup, a regular meeting of rustaceans here. Martin talked about WebRender; I talked about refactoring C to port it to Rust, and then Alex talked about Rust's plans for 2018. Fun times.

  • 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?

  • Getting Real GNOME Back in Ubuntu 18.04 [Quick Tip]

    Ubuntu 18.04 uses a customized version of GNOME and GNOME users might not like those changes. This tutorial shows you how to install vanilla GNOME on Ubuntu 18.04.

    One of the main new features of Ubuntu 18.04 is the customized GNOME desktop. Ubuntu has done some tweaking on GNOME desktop to make it look similar to its Unity desktop.

    So you get minimize options in the windows control, a Unity like launcher on the left of the screen, app indicator support among some other changes.

  • 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.

    Both of these Xfce Settings updates bring better multi-monitor support, including visualization of all display configuration states, visually noting if two displays are mirrored, always drawing the active display last so it's on top, and a number of fixes pertaining to the multi-monitor display handling from this Xfce desktop settings agent.

DragonFlyBSD 5.2, TrueOS 18.03, FreeBSD 11.1, Ubuntu 16.04/18.04 & Clear Linux Tests

Filed under
Graphics/Benchmarks

This week I posted some benchmarks looking at the Meltdown mitigation impact on BSD vs. Linux as well as some tests of DragonFly's stabilized HAMMER2 while for your viewing pleasure this weekend are a variety of general BSD vs. Linux benchmarks while using the newly-released DragonFlyBSD 5.2, TrueOS 18.03, FreeBSD 11.1, Ubuntu 16.04 LTS, Ubuntu 18.04, and Intel's Clear Linux.

All of these BSD/Linux operating system benchmarks were done using a system with an Intel Xeon E3-1280 v5 Skylake CPU, MSI MS-7998 motherboard, 2 x 8GB DDR4-2133 memory, and a 256GB Toshiba RD-400 NVMe SSD. All of the hardware components were maintained the same throughout the entire testing process.

For making the systems comparable and testing the operating systems in the manner set by the vendor, each platform was tested "out of the box" using the default settings.

  • The developer of Helium Rain gave an update on their sales, low overall sales but a high Linux percentage

    Helium Rain [Steam, Official Site], the gorgeous space sim from Deimos Games is really quite good so it's a shame they've seen such low overall sales. In total, they've had around 14,000€ (~$17,000) in sales which is not a lot for a game at all.

    The good news, is that out of the two thousand copies they say they've sold, a huge 14% of them have come from Linux. It's worth noting, that number has actually gone up since we last spoke to them, where they gave us a figure of 11% sales on Linux.

  • IRS Website Crash Reminder of HealthCare.gov Debacle as OMB Pushes Open Source

    OMB is increasingly pushing agencies to adopt open source solutions, and in 2016 launched a pilot project requiring at least 20 percent of custom developed code to be released as open source – partly to strengthen and help maintain it by tapping a community of developers. OMB memo M-16-21 further asks agencies to make any code they develop available throughout the federal government in order to encourage its reuse.

    “Open source solutions give agencies access to a broad community of developers and the latest advancements in technology, which can help alleviate the issues of stagnated or out-dated systems while increasing flexibility as agency missions evolve over time,” says Henry Sowell, chief information security officer at Hortonworks Federal. “Enterprise open source also allows government agencies to reduce the risk of vendor lock-in and the vulnerabilities of un-supported software,” he adds.

  • Migrations: the sole scalable fix to tech debt.

    Migrations are both essential and frustratingly frequent as your codebase ages and your business grows: most tools and processes only support about one order of magnitude of growth before becoming ineffective, so rapid growth makes them a way of life. This isn't because they're bad processes or poor tools, quite the opposite: the fact that something stops working at significantly increased scale is a sign that it was designed appropriately to the previous constraints rather than being over designed.

GitLab Web IDE

  • GitLab Web IDE Goes GA and Open-Source in GitLab 10.7
    GitLab Web IDE, aimed to simplify the workflow of accepting merge requests, is generally available in GitLab 10.7, along with other features aimed to improve C++ and Go code security and improve Kubernets integration. The GitLab Web IDE was initially released as a beta in GitLab 10.4 Ultimate with the goal of streamlining the workflow to contribute small fixes and to resolve merge requests without requiring the developer to stash their changes and switch to a new branch locally, then back. This could be of particular interest to developers who have a significant number of PRs to review, as well as to developers starting their journey with Git.
  • GitLab open sources its Web IDE
    GitLab has announced its Web IDE is now generally available and open sourced as part of the GitLab 10.7 release. The Web IDE was first introduced in GitLab Ultimate 10.4. It is designed to enable developers to change multiple files, preview Markdown, review changes and commit directly within a browser. “At GitLab, we want everyone to be able to contribute, whether you are working on your first commit and getting familiar with git, or an experienced developer reviewing a stack of changes. Setting up a local development environment, or needing to stash changes and switch branches locally, can add friction to the development process,” Joshua Lambert, senior product manager of monitoring and distribution at GitLab, wrote in a post.

Linux Kernel Maintainer Statistics

As part of preparing my last two talks at LCA on the kernel community, “Burning Down the Castle” and “Maintainers Don’t Scale”, I have looked into how the Kernel’s maintainer structure can be measured. One very interesting approach is looking at the pull request flows, for example done in the LWN article “How 4.4’s patches got to the mainline”. Note that in the linux kernel process, pull requests are only used to submit development from entire subsystems, not individual contributions. What I’m trying to work out here isn’t so much the overall patch flow, but focusing on how maintainers work, and how that’s different in different subsystems. Read more

Security: Updates, Trustjacking, Breach Detection

  • Security updates for Monday
  • iOS Trustjacking – A Dangerous New iOS Vulnerability
    An iPhone user's worst nightmare is to have someone gain persistent control over his/her device, including the ability to record and control all activity without even needing to be in the same room. In this blog post, we present a new vulnerability called “Trustjacking”, which allows an attacker to do exactly that. This vulnerability exploits an iOS feature called iTunes Wi-Fi sync, which allows a user to manage their iOS device without physically connecting it to their computer. A single tap by the iOS device owner when the two are connected to the same network allows an attacker to gain permanent control over the device. In addition, we will walk through past related vulnerabilities and show the changes that Apple has made in order to mitigate them, and why these are not enough to prevent similar attacks.
  • What Is ‘Trustjacking’? How This New iOS Vulnerability Allows Remote Hacking?
    This new vulnerability called trustjacking exploits a convenient WiFi feature, which allows iOS device owners to manage their devices and access data, even when they are not in the same location anymore.
  • Breach detection with Linux filesystem forensics
    Forensic analysis of a Linux disk image is often part of incident response to determine if a breach has occurred. Linux forensics is a different and fascinating world compared to Microsoft Windows forensics. In this article, I will analyze a disk image from a potentially compromised Linux system in order to determine the who, what, when, where, why, and how of the incident and create event and filesystem timelines. Finally, I will extract artifacts of interest from the disk image. In this tutorial, we will use some new tools and some old tools in creative, new ways to perform a forensic analysis of a disk image.
