  • Codeplay Launches Open-Source 'SYCL Academy' To Learn This Increasingly Popular Standard

    While SYCL has been around for five years as a Khronos standard providing a single-source C++ programming model for exploiting OpenCL, it has yet to reach its prime but demand for it is picking up with Intel working to upstream their SYCL back-end in LLVM, SYCL becoming part of their programming model with oneAPI and Xe Graphics, and other vendors also jumping on the SYCL bandwagon. Codeplay has now provided an open-source SYCL learning code for those interested in this higher-level alternative to straight OpenCL programming.

  • Open-Source Build and Test Tool Bazel Reaches 1.0

    Derived from Google's internal build tool Blaze, Bazel is a build and test tool that offers a human-readable definition language and is particularly aimed at large, multi-language, multi-repositories projects. Originally open-sourced in 2015, Bazel has now reached 1.0.

    One of the major implications of reaching version 1.0 for Bazel is the promise of greater stability and backward-compatibility guarantees. This has been a historical pain point for Bazel users, who often found themselves in the situation of having to rewrite part of their build rules due to frequent breaking changes in Bazel or its ecosystem. Accordingly, the Bazel team has committed to following semantic versioning for future Bazel releases, meaning only major versions will be allowed to include breaking changes. Furthermore, the team committed to maintaining a minimum stability window of three months between major versions.

  • DevOps Deeper Dive: DevOps Accelerates Open Source Innovation Pace

    That rate of innovation has increased dramatically in the last few years. However, much of that innovation would not have been possible if large swaths of the open source community hadn’t been able to employ best DevOps practices to collaborate, said CloudBees CEO Sacha Labourey.


    None of this shift has been lost on IT vendors. As the demand for proprietary code slackened, many found it profitable to offer support services for open source software. The more there is to consume, the more the support services contracts grew. Now every vendor from IBM to small IT services providers such as Fairwinds has launched open source projects that help drive demand for IT services expertise.

    “There’s pain around integrating a lot of disparate open source projects,” said Robert Brennan, director of open source software for Fairwinds. “Organizations may be getting software for free, but there’s usually not a lot of help around.”

    Now almost every IT vendor in the world is making software engineers available to work on open source projects. All that talent focused on open source projects has led to the development of new platforms such as Jenkins, GitHub, Kubernetes and, more recently, a raft of smaller projects. With the rise of containers and cloud-native applications, open source software projects are entering another era that will see many of those same software engineers leveraging DevOps practices more broadly to drive even more innovative projects at increasingly faster rates.

  • Find your next developer from open source communities

    Meanwhile, demand for data scientists is rising as companies seek AI-based solutions to stay competitive. Demand is reflected in salary offers. Companies competing to hire and retain data experts are offering on average more than US$100,000, making it one of the most highly paid professions in the States.

    For companies lacking the budget to hire or train in-house staff to fill the role, they may find themselves struggling with maintaining technological infrastructure or moving forward with plans for digitization.

    Therefore, open source learning and further development of communities could be the solution to this gap.

    An IBM grant to support open source communities such as Girls Who Code, a non-profit organization offering coding lessons for women in the US, is a step forward to filling in a shortage of software developers.

One open source chat tool to rule them all

Last year, I brought you 19 days of new (to you) productivity tools for 2019. This year, I'm taking a different approach: building an environment that will allow you to be more productive in the new year, using tools you may or may not already be using. Instant messaging and chat have become a staple of the online world. And if you are like me, you probably have about five or six different apps running to talk to your friends, co-workers, and others. It really is a pain to keep up with it all. Thankfully, you can use one app (OK, two apps) to consolidate a lot of those chats into a single point. Read more

  • Experimental Support For C++20 Coroutines Has Landed In GCC 10

    As of this morning experimental support for C++20 coroutines has been merged into the GCC 10 compiler! Coroutines allow a function to have its execution stopped/suspended and then to be resumed later. Coroutines is one of the big features of C++20. Sample syntax and more details on C++ coroutines can be found at Coroutines support for GCC has been under development for months and now as a late addition to GCC 10 is the experimental implementation.

  • GNU Binutils 2.34 Branched - Bringing With It "debuginfod" HTTP Server Support

    With GNU Binutils 2.34 comes debuginfod support, which is the HTTP server catching our eye while the debuginfod server is distributed as part of the latest elfutils package. This isn't for a general purpose web server thankfully but is an HTTP server for distributing ELF/DWARF debugging information and source code. With debuginfod enabled, Binutils' readelf and objdump utilities can query the HTTP server(s) for debug files that cannot otherwise be found. Enabling this option requires building Binutils using --with-debuginfod.

  • Announcing git-cinnabar 0.5.3

    Git-cinnabar is a git remote helper to interact with mercurial repositories. It allows to clone, pull and push from/to mercurial remote repositories, using git.

  • Steve Kemp: Announce: github2mr

    myrepos is an excellent tool for applying git operations to multiple repositories, and I use it extensively. I've written several scripts to dump remote repository-lists into a suitable configuration format, and hopefully I've done that for the last time.

  • Term::ANSIColor 5.01

    This is the module included in Perl core that provides support for ANSI color escape sequences. This release adds support for the NO_COLOR environment variable (thanks, Andrea Telatin) and fixes an error in the example of uncolor() in the documentation (thanks, Joe Smith). It also documents that color aliases are expanded during alias definition, so while you can define an alias in terms of another alias, they don't remain linked during future changes.

  • Python 3.7.5 : Django security issues - part 001.

    Django like any website development and framework implementation requires security settings and configurations. Today I will present some aspects of this topic and then I will come back with other information.

  • How to display flash messages in Django templates

    Sometimes we need to show the one-time notification, also known as the flash messages in our Django application. For this Django provides the messages framework. We are going to use the same here. To show flash messages in the Django application, we will extend our previous project Hello World in Django 2.2. Clone the git repository, check out the master branch and set up the project on your local machine by following the instructions in the README file.

KDE: Videos, Plasma and Itinerary

  • So you want to make a KDE video...

    KDE is running a competition in search of the next great promotional video for KDE's Plasma desktop and KDE's applications. The prizes are two fantastic TUXEDO computers, one per category, which will undoubtedly boost your film rendering capacity. There are also 12 goodie packages for runner-ups, and who doesn't need more Linux shirts, caps and stickers? Although we have already received some interesting entries, we feel it may be time to help video artists out there with ideas from the judges themselves. Below, Julian Schraner, Ivana Isadora Devčić, and Paul Brown from the Promo team and Farid Abdelnour from the Kdenlive team give their views on what a KDE promotional video should look like, where to find resources, and which pitfalls may hurt your film if you fall for them.

  • Learning about our users

    In a product like Plasma, knowing the kind of things our existing users care about and use sheds light on what needs polishing or improving. At the moment, the input we have is either the one from the loudest most involved people or outright bug reports, which lead to a confirmation bias. What do our users like about Plasma? On which hardware do people use Plasma? Are we testing Plasma on the same kind of hardware Plasma is being used for? Some time ago, Volker Krause started up the KUserFeedback framework with two main features. First, allowing to send information about application’s usage depending on certain users’ preferences and include mechanisms to ask users for feedback explicitly. This has been deployed into several products already, like GammaRay and Qt Creator, but we never adopted it in KDE software. The first step has been to allow our users to tune how much information Plasma products should be telling KDE about the systems they run on.
