  • hipSYCL Gets New Compilation Toolchain For Taking SYCL Directly To CUDA & ROCm

    Could 2019 be the year that SYCL really takes off for this single-source C++-based programming model? There's certainly a lot of interesting projects going on around SYCL. 

    Intel is making very interesting moves and among them are working on upstreaming SYCL support in LLVM. It appears this SYCL play of theirs will be a key part of their "oneAPI" effort that is supposed to be out by year's end.

  • How to Extract Build Info from Jenkins with Python

    The Python Jenkins package will work with both Hudson and Jenkins which JenkinsAPI only works with Jenkins. I usually use Python Jenkins because of this, although I have recently started looking to see which one works better with artifacts and I discovered that JenkinsAPI is actually better for that sort of thing. So you will need to evaluate both of these packages depending on what you need to do.

  • Stylin’ with Pandas

    I have been working on a side project so I have not had as much time to blog. Hopefully I will be able to share more about that project soon.

    In the meantime, I wanted to write an article about styling output in pandas. The API for styling is somewhat new and has been under very active development. It contains a useful set of tools for styling the output of your pandas DataFrames and Series. In my own usage, I tend to only use a small subset of the available options but I always seem to forget the details. This article will show examples of how to format numbers in a pandas DataFrame and use some of the more advanced pandas styling visualization options to improve your ability to analyze data with pandas.

  • Introducing SwiftWasm, a tool for compiling Swift to WebAssembly

    The SwiftWasm tool is built on top of the WASI SDK, which is a WASI-enabled C/ C++ toolchain. This makes the WebAssembly executables generated by SwiftWasm work on both browsers and standalone WebAssembly runtimes such as Wasmtime, Fastly’s Lucet, or any other WASI-compatible WebAssembly runtime.

  • NodeRun Is Node.js For Everyone

    NodeRun is the free, easy, and social way to develop and deploy full-stack, enterprise-ready Node.js applications. We provide the cloud-based visual IDE, the database, and the server – you just need to bring your imagination.

    We built NodeRun with business application development in mind. You can develop line-of-business applications faster than by traditional methods, making it an ideal solution for new and experienced Node.js developers alike. When you create an application in NodeRun, we provide you with a small instance of Ubuntu Linux, a MariaDB database, and a Node.js server running Express and our Profound.js framework. Everything you need to start developing your application and all running in the cloud.

  • Alberto Flores (albertoefg): New beginning

    Over the last few days I've had a few great news and some small wins. I was accepted in Google Summer of Code as a contributor to Krita, this gave me so much happiness. I also got my passport so I feel one step closer to the Krita Sprint and it is going to be awesome, I am really excited to meet everyone because everyone who is part of Krita has been great to me, Krita has this great positive community. I also started to do contributions to the manual and even though is something small I feel proud of myself. I also asked for a KDE Developer Account.

    I also had been going out more and working out, which is a nice change after being depressed and solitary for so long. And I've been more happy and optimist about life in general. I also got my grades for this four month period: 9.9,9.8,9.7,9.0,9.0, so I had a good period, but a new one has started already.

    Every few cycles we check in on the release process for Kubernetes itself. Last year we interviewed the release managers for Kubernetes 1.11, and shared that transcript on the Kubernetes blog. We got such great feedback that we wanted to share the transcript of our recent conversation with Aaron Crickenberger, the release manager for Kubernetes 1.14.

  • Learn Python by teaching in your community

    Since ancient times, we've known that one of the most effective ways to learn something is by teaching it to someone else. I've put that strategy into practice by teaching Python in my community. If you want to learn Python for free and have fun at the same time, I recommend you consider doing the same.

    I started on this journey about six years ago, based on the recommendation of a friend who was teaching himself Python. It all came together about a year later when I bought my first Raspberry Pi and learned about the Turtle module in Python.

    The Turtle was an epiphany that changed my life and perception of myself as a learner. Turtle graphics helped me understand mathematics and its relevance in my life. I began to explore Python vigorously and, as I gained confidence, I started sharing my newfound knowledge with the teachers and students I came in contact with.

  • Don't test in production? Test in production!

    If you last updated your IT security standards five or more years ago, chances are they don't line up well with the realities of today's DevOps and site reliability engineering (SRE) practices. One particularly sticky topic is testing in production—and, thus, testing with production data—because DevOps and SRE blur the line between what is production and what is not; what is a test and what is not.

  • On the Rookout for live data: Instant observability to fix software bugs and open AI black boxes

    Software bugs are a pain: buggy software can drop anything from your sales to aircraft in mid-flight. Debugging software is hard, tedious, and costs a fortune. A multitude of frameworks and processes have been created to facilitate software testing and ensure fewer bugs make it to production, and invariably they all fail from time to time.

    When this happens, the pain for software developers and the nail-biting for businesses starts. Developers have to find the source code that caused the bug, and execute this in a test environment that resembles the production one as closely as possible. The situation that caused the bug has to be recreated, too.

    The way this usually works is by adding logging statements and breakpoints in the code, and retracing execution in the code and its dependencies until the bug is located and can be fixed. Then the new code has to be rebuilt and redeployed in production.

  • How GitLab Cracked The Code Of Remote Working: GitLab Contribute Report

    Industrial revolutions changed our world. They built the foundations of the modern civilizations. But there were some side effects of these revolutions, too. One of the biggest “damages” industrial revolutions did to our society was breaking families apart. We have to leave our homes, our kids, our loved ones behind and go to ‘work’. We spend several years of our lives in just commuting to work.

  • ActiveState survey: developers spend 20 percent less time on programming compared to 2018

    Security, stability and managing dependencies of open source languages have been keeping developers from fully using their time toward what they do best: programming. A recent ActiveState survey titled “2019 Developer Survey: Open Source Runtimes” found that developers spend 20 percent less time on programming than last year.

    The survey included responses from 1,250 developers, 65 percent of whom consider themselves professional developers, from all over the world.

    According to the survey, about half of the developers ranked adding or incorporating a new language as difficult to very difficult. More than 61 percent said they spend four hours or less per day on programming and 65 percent said they don’t contribute or maintain open source projects. About half of those developers blamed a lack of time.

  • Google is starting to reveal the secrets of its experimental Fuchsia OS

    Google Fuchsia remains shrouded in mystery, but the company is slowly beginning to open up about the next-generation operating system, what its purpose is, and what devices it might power. At Google’s I/O developer conference this past week, Android and Chrome chief Hiroshi Lockheimer offered some rare insight into Fuchsia, albeit at a very high level, in front of public audiences.

    What we do know about Fuchsia is that it’s an open source project, similar to AOSP, but could run all manner of devices, from smart home gadgets to laptops to phones. It’s also known to be built on an all-new, Google-built kernel called “zircon,” formerly known as “magenta,” and not the Linux kernel that forms the foundation of Android and Chrome OS.

  • Google launches Jetpack Compose, an open-source, Kotlin-based UI development toolkit

    Google today announced the first preview of Jetpack Compose, a new open-source UI toolkit for Kotlin developers who want to use a reactive programming model similar to React Native and Vue.js.

    Jetpack Compose is an unbundled toolkit that is part of Google’s overall Android Jetpack set of software components for Android developers, but there is no requirement to use any other Jetpack components. With Jetpack Compose, Google is essentially bringing the UI-as-code philosophy to Android development. Compose’s UI components are fully declarative and allow developers to create layouts by simply describing what the UI should look like in their code. The Compose framework will handle all the gory details of UI optimization for the developer.

If you make use of Linux kernel live-patching or even just have CONFIG_LIVEPATCH enabled, when switching to Linux 5.2 and building with GCC 9, the performance may be impacted in select workloads.

The Linux livepatching infrastructure updates were sent in this week for the Linux 5.2 kernel merge window. The changes aren't too exciting but does include the change we previously outlined of turning on GCC 9's live-patching option as part of the kernel build when CONFIG_LIVEPATCH is enabled.
