  • Switch A Django Project To Use Pytest - Building SaaS #57

    In this episode, I replaced the default Django test runner to use pytest. We walked through installation, configuration, how to change tests, and the benefits that come from using pytest.

    We started by looking at the current state of the test suite to provide a baseline to compare against. After that, I went to PyPI to find the version of pytest-django that we wanted to install. I added the package to my requirements-dev.txt and installed the update.

  • Oracle’s Linux Team Wishes the Java Community a Happy 25th

    From one open source community to another, Oracle’s Linux team would like to congratulate the Java community on its 25th anniversary! Java has an impressive history. It was a breakthrough in programming languages, allowing developers to write once and have code run anywhere. And, it has enabled developers to create a myriad of innovative solutions that help run our world. Read Georges Saab’s post to learn more.

    Both open source technologies, Java and Linux benefit from communities that collectively drive their advancements. While the technologies aren’t similar, there are areas where both work together and complement each other.

    One area is Java’s support for Linux HugePages. Using Linux HugePages can improve system performance by reducing the amount of resources needed to manage memory. The result of less overhead in the system means more resources are available for Java and the Java app, which can make both run faster.

  • New Training Course Advances Knowledge to Encourage Node.js Application Development Careers

    LFW211, developed in conjunction with the OpenJS Foundation, is geared toward developers who wish to master and demonstrate Node.js specialization, in particular for creating Node.js applications. The course provides core skills for effectively harnessing a broad range of Node.js capabilities at depth, equipping developers with rigorous foundational skills and knowledge that will translate to building any kind of Node.js application or library.

Java programming language celebrates 25 years

  • Java programming language celebrates 25 years

    The Java programming language celebrates its silver anniversary this week, with May 23, 2020, marking 25 years from the day Sun Microsystems first introduced Java to the world. The venerable language has remained popular with enterprises even as a slew of rival languages, such as Python and Go, now compete for the hearts and minds of software developers. But Java is not standing still, with a revamp designed to address longtime pain points now in the offing.

    Arising out of the “Oak” project begun in 1991 and spearheaded by James Gosling, object-oriented Java gained fame for its “write once, run anywhere” portability, as the Java Virtual Machine supported multiple hardware platforms and operating systems, and Java applets could be run from a webpage. Java applets offered better performance than JavaScript for many years, but eventually fell out of favor with browser makers and were removed from Java in 2018.

Mozilla: Accessibility, Net Neutrality, AMP and Rust

  • Mozilla Accessibility: Broadening Our Impact

    Last year, the accessibility team worked to identify and fix gaps in our screen reader support, as well as on some new areas of focus, like improving Firefox for users with low vision. As a result, we shipped some great features. In addition, we’ve begun building awareness across Mozilla and putting in place processes to help ensure delightful accessibility going forward, including a Firefox wide triage process. With a solid foundation for delightful accessibility well underway, we’re looking at the next step in broadening our impact: expanding our engagement with our passionate, global community. It’s our hope that we can get to a place where a broad community of interested people become active participants in the planning, design, development and testing of Firefox accessibility. To get there, the first step is open communication about what we’re doing and where we’re headed.

  • Mozilla Open Policy & Advocacy Blog: Next Steps for Net Neutrality

    Two years ago we first brought Mozilla v. FCC in federal court, in an effort to save the net neutrality rules protecting American consumers. Mozilla has long fought for net neutrality because we believe that the internet works best when people control their own online experiences. Today is the deadline to petition the Supreme Court for review of the D.C. Circuit decision in Mozilla v. FCC. After careful consideration, Mozilla—as well as its partners in this litigation—are not seeking Supreme Court review of the D.C. Circuit decision. Even though we did not achieve all that we hoped for in the lower court, the court recognized the flaws of the FCC’s action and sent parts of it back to the agency for reconsideration. And the court cleared a path for net neutrality to move forward at the state level. We believe the fight is best pursued there, as well as on other fronts including Congress or a future FCC. Net neutrality is more than a legal construct. It is a reflection of the fundamental belief that ISPs have tremendous power over our online experiences and that power should not be further concentrated in actors that have often demonstrated a disregard for consumers and their digital rights. The global pandemic has moved even more of our daily lives—our work, school, conversations with friends and family—online. Internet videos and social media debates are fueling an essential conversation about systemic racism in America. At this moment, net neutrality protections ensuring equal treatment of online traffic are critical. Recent moves by ISPs to favor their own content channels or impose data caps and usage-based pricing make concerns about the need for protections all the more real.

  • Frédéric Wang: Contributions to Web Platform Interoperability (First Half of 2020)

    Web developers continue to face challenges with web interoperability issues and a lack of implementation of important features. As an open-source project, the AMP Project can help represent developers and aid in addressing these challenges. In the last few years, we have partnered with Igalia to collaborate on helping advance predictability and interoperability among browsers. Standards and the degree of interoperability that we want can be a long process. New features frequently require experimentation to get things rolling, course corrections along the way and then, ultimately as more implementations and users begin exploring the space, doing really interesting things and finding issues at the edges we continue to advance interoperability. Both AMP and Igalia are very pleased to have been able to play important roles at all stages of this process and help drive things forward. During the first half of this year, here’s what we’ve been up to…

Games: Oxygen Not Included, Proton, GDScript

  • The first DLC for Oxygen Not Included sounds huge, free update soon too

    Klei Entertainment have been busy working behind the scenes on the next free update and first expansion for Oxygen Not Included and they've detailed what's coming. First, the free update coming within the next few days should fix plenty of issues, including one involving infinite digging which sounds annoying. More exciting is the DLC though, it's sounding like it's going to be massive!

  • VKD3D-Proton is the new official Direct3D 12 to Vulkan layer for Proton

    VKD3D was originally a project created directly by the Wine team, the compatibility layer that Proton is built upon. However, the original founder passed away and it seems Valve-funded developers are taking the torch to push it much further. It's actually been a thing for a while but today they adjusted the name of their project as VKD3D-Proton, to give it some official status plus preventing any naming conflicts elsewhere and just be clear about their goals. They're going for supporting the "full" Direct3D 12 API on top of Vulkan, with an aim of both performance and compatibility using modern Vulkan extensions and features, so this comes at the expense of compatibility with older drivers and GPUs. They're also not looking to keep backwards compatibility with the original vkd3d.

  • GDScript progress report: Type checking is back

    After completing the new tokenizer and parser as mentioned in the previous reports, I started working on the code analyzer, which is responsible for type checking and also for used for other features like warnings and some optimizations. This was done before as a second pass inside the parser but it was now moved to another class to make it clear that it doesn't happen at the same pass thus avoiding issues with functions being called out of order (which happened by a few contributions that missed this detail).
