  • Quarkus: Modernize “helloworld” JBoss EAP quickstart, Part 1

    Quarkus is, in its own words, “Supersonic subatomic Java” and a “Kubernetes native Java stack tailored for GraalVM & OpenJDK HotSpot, crafted from the best of breed Java libraries and standards.” Red Hat JBoss Enterprise Application Platform (JBoss EAP) quickstarts are a good starting point for understanding how to modernize brownfield Java EE 8 applications that run on JBoss EAP.

    It’s important to note that both Quarkus and JBoss EAP rely on providing developers with tools based—as much as possible—on standards. If your application is not already running on JBoss EAP, there’s no problem. You can migrate it from your current application server to JBoss EAP using the Red Hat Application Migration Toolkit. After that, the final and working modernized version of the code is available in the https://github.com/mrizzi/jboss-eap-quickstarts/tree/quarkus repository inside the helloworld module.

  • PHP version 7.2.25RC1 and 7.3.12RC1

    Release Candidate versions are available in testing repository for Fedora and Enterprise Linux (RHEL / CentOS) to allow more people to test them. They are available as Software Collections, for a parallel installation, perfect solution for such tests, and also as base packages.

    RPM of PHP version 7.3.12RC1 are available as SCL in remi-test repository and as base packages in the remi-test repository for Fedora 30-31 or remi-php73-test repository for Fedora 29 and Enterprise Linux.

    RPM of PHP version 7.2.25RC1 are available as SCL in remi-test repository and as base packages in the remi-test repository for Fedora 29 or remi-php72-test repository for Enterprise Linux.

  • Bodhi 5.0.0 released
  • Tuning your bash or zsh shell on Fedora Workstation and Silverblue

    This article shows you how to set up some powerful tools in your command line interpreter (CLI) shell on Fedora. If you use bash (the default) or zsh, Fedora lets you easily setup these tools.

  • Accommodating Flock in the release schedule

    Jiří Konečný posted a request on the devel list a few weeks ago—he wanted to require a successful compose before the release is branched from Rawhide. As often happens, it’s not as simple as it seems on the surface, and the discussion eventually came around to not branching right after Flock.

    This, too, isn’t as simple as it might seem. Changing one milestone in the schedule has impacts on the remaining milestones. We can make changes, of course, but we want to make sure we’re aware of the potential side effects. After discussing this with Mohan Boddu of the release engineering team, I have a few possible alternatives.

The world's fastest supercomputers hit higher speeds than ever with Linux

Yes, there's a lot of talk now about how quantum computers can do jobs in 200 seconds that would take the world's fastest supercomputers 10,000 years. That's nice. But the simple truth is, for almost all jobs, supercomputers are faster than anything else on the planet. And, in the latest Top 500 supercomputer ratings, the average speed of these Linux-powered racers is now an astonishing 1.14 petaflops. The fastest of the fast machines haven't changed since the June 2019 Top 500 supercomputer list. Leading the way is Oak Ridge National Laboratory's Summit system, which holds top honors with an HPL result of 148.6 petaflops. This is an IBM-built supercomputer using Power9 CPUs and NVIDIA Tesla V100 GPUs. Read more

Programming: Django, Python and Qt

  • Introducing DjangoCon Africa

    Following the huge success of PyCon Africa, the Django community in Africa is ready to bring a new major software event to the continent - the very first DjangoCon Africa! The Django Software Foundation is excited to endorse and support this initiative. Plans are already in motion for a DjangoCon Africa to be held in Addis Ababa, Ethiopia in November 2020. Actual dates to be announced as soon as key details are in place. DjangoCon Africa will include 3 days of single-track talks, 1 day of workshops and sprints, and another day for touring for international visitors. The event will also include a Django Girls workshop to be held the weekend before DjangoCon Africa. To make the conference as inclusive as possible, the event will offer financial aid to members of under-represented communities in software to ensure they can also attend.

  • Django 3.0 release candidate 1 released

    Django 3.0 release candidate 1 is the final opportunity for you to try out the raft of new features before Django 3.0 is released. The release candidate stage marks the string freeze and the call for translators to submit translations. Provided no major bugs are discovered that can't be solved in the next two weeks, Django 3.0 will be released on or around December 2. Any delays will be communicated on the django-developers mailing list thread.

  • Cyber Discovery - What it is all about

    Cyber Discovery is made of 4 rounds. The first one being CyberStart Assess. It ran from the 3rd September to the 25th October 2019. There are 10 challenges starting easy, getting much harder. The aim for most of the challenges are to use 'Inspect Element' to get into the website and find the flag. I completed all of these challenges and was invited onto the next round: CyberStart Game. CyberStart Game is much more about finding things out yourself. A useful tip if you are stuck is to search for help on Google. CyberStart Game has 3 'Bases': Headquarters where you get to take part in lots of varied challenges, Moon Base where you learn the basics of Python and Internet Tools that can be run in python e.g. FTP... You also learn how to use python to Brute Force password protected ZIP files and other securities. The Forensics Base is, well you can guess: Forensics. It teaches you about Cryptography and other hiding methods.

  • PyDev of the Week: Martin Uribe

    While taking some college courses I learned Java, but I didn’t like it much. I know enough of the following to get things done: HTML, CSS, JavaScript, Perl, SQL, and BASH. Python is my favorite; I use it pretty much every day even though my job doesn’t require me to code.

  • You can now hone your testing / pytest skills on our platform

    Writing test code is an essential skill. As PyBites we believe writing code is the only solution to becoming a master (Ninja) at programming. The same applies to test code. For that reason we extended our regular exercises with Test Bites. In this article you will read about the feature showcasing it on our first ever Test Bite. We also share some details around implementation and a challenge we hit getting it to work. Enjoy and start honing your testing skills today!

  • unu – Using Qt on embedded Linux

    Right from the start, unu wanted to add a stylish, first-class embedded high-res display to their second generation electric scooter. Like many top-class engineering companies, unu didn’t have in-house expertise for building a modern UI, so they decided to partner with KDAB to build a modern UI based on Qt. In this video you learn more about the development process in this project and why unu chose KDAB as a partner.

Google and fwupd sitting in a tree

I’ve been told by several sources (but not by Google directly, heh) that from Christmas onwards the “Designed for ChromeBook” sticker requires hardware vendors to use fwupd rather than random non-free binaries. This does make a lot of sense for Google, as all the firmware flash tools I’ve seen the source for are often decades old, contain layer-on-layers of abstractions, have dubious input sanitisation and are quite horrible to use. Many are setuid, which doesn’t make me sleep well at night, and I suspect the security team at Google also. Most vendor binaries are built for the specific ODM hardware device, and all of them but one doesn’t use any kind of source control or formal review process. The requirement from Google has caused mild panic among silicon suppliers and ODMs, as they’re having to actually interact with an open source upstream project and a slightly grumpy maintainer that wants to know lots of details about hardware that doesn’t implement one of the dozens of existing protocols that fwupd supports. These are companies that have never had to deal with working with “outside” people to develop software, and it probably comes as quite a shock to the system. To avoid repeating myself these are my basic rules when adding support for a device with a custom protocol in fwupd: I can give you advice on how to write the plugin if you give me the specifications without signing an NDA, and/or the existing code under a LGPLv2+ license. From experience, we’ll probably not end up using any of your old code in fwupd but the error defines and function names might be similar, and I don’t anyone to get “tainted” from looking at non-free code, so it’s safest all round if we have some reference code marked with the right license that actually compiles on Fedora 31. Yes, I know asking the legal team about releasing previously-nonfree code with a GPLish licence is difficult. Read more
