SD Times Open Source Project of the Week: Bazel

Filed under
Google
OSS

The project is led by a core group of contributors and Googlers, and managed by the community. The group of core contributors is self-managing and added by two supporting votes from other core contributors.

According to Google, some parts of Bazel will never make it into open source because it integrates with Google-specific technology or the company plans to get rid of those features in the future.

The Angular team has announced plans to migrate its build scripts with Bazel to get faster and more reliable incremental builds. As of Angular 6, Angular itself is now built with Bazel, according to Stephen Fluin, developer advocate for Angular. “Bazel is the build system that Google and the Angular team use to keep incremental builds under 2 seconds,” the team wrote in a post.

Bazel is already being used by companies such as Asana, Ascend.io, Databricks, Dropbox, Etsy, Google, Huawei, LingoChamp, Pinterest and Uber. Open-source projects using Bazel include Angular, Deepmind Lab, GRPC, gVisor, Kubernetes, Sonnet, TensorFlow and Trunk.

  • GSoC 2018 with GNOME: Internationalization of Fractal (part 1)

    It is the beginning of the coding period and I will first work on investigating on implementing the internationalization of Fractal and then find a way to do it. At this moment, internationalization support in Rust is limited and new, so no GTK application written in Rust have implemented it yet. And it is very exciting to work on this with this perspective, furthermore because I will write some blogposts that will try to explain how to do it and I hope it could help other people to do so!

  • Implementation of the PartialEq trait for Message
  • Improving the development experience for GNOME Settings

    After Bastien and Rui announced that they were stepping down from maintainership of GNOME Settings, I went ahead and volunteered to take care of it. This was not a random act, though; for quite some time, I’ve been adding and changing code all around. I was pretty involved in moving to the new layout, and with the help of other contributors, implemented the redesigns of various panels. Clearly, I have a technical debt to the app.

    Adding to that, assuming maintainership over it also aligns well with the goals of my employer, Endless, and gives a nice upstream/downstream overlap. With that, I can spend a bigger chunk of my work time on upstream tasks. Moreover, it allows us to have a stronger relationship with the GNOME community — after all, it allows me to bridge the insights and knowledge we gain from our users to a wider community.

  • Google Summer of Code 2018 at GNOME

    Hi! I am Aditya Manglik from Wien, a.k.a. carpediem on IRC. Currently I am pursuing a Bachelor’s thesis in Deep Learning from TU Wien. I am interested in software, operating systems and AI. Travel, hiking and football occupy rest of the time.

    I started with Linux ~7 years ago when my Windows desktop failed to boot because of a curious experiment accident with system32 files. Looking back at that moment, I am glad for the few hours of initial pain which was worth several years of sanity. Since then I have been working with Linux as the primary platform. I like Open Source Software because it’s much more fun to break and fix something, which really helps understand what’s happening in the machine. I used to like C/ C++ quite a bit, but you can probably throw any language and I am happy to learn it.

  • A closer look at Chrome OS using LXD to run Linux GUI apps (Project Crostini)

    Project Crostini is the Chrome OS project to add support to run Linux GUI apps on Chrome OS.

    The components that facilitate Project Crostini can be found at https://github.com/lstoll/cros-crostini That page has instructions for those that wanted to enable the running of Linux GUI apps on Chrome OS, when Project Crostini was still under development. Lincoln Stoll dissected the source of Chrome OS and created a helpful list of the involved repositories.

    The basic component is The Chrome OS Virtual Machine Monitor (crossvm), which runs untrusted operating systems through Linux’s KVM interface. The Linux distribution would run in a VM. The test repositories make reference to the X server, XWayland and Wayland. There is a repository called sommelier, which is a nested Wayland compositor with X11 forwarding support. It needs more searching to figure out where the source code ended into the Chrome OS repository and what is actually being used.

    Update #1: Here are the vm_tools in Chrome OS. They include garcon, a service that gets added in the container and communicates with another service outside of the container (vm_concierge).

    What is important, is that LXD runs in this VM and is configured to launch a machine container with a Linux distribution. We are going in depth into this.

  • Android P to improve users' network privacy

    The forthcoming Android P release will protect the operating system's network processes against snoops and nasties.

    Android's problems lie in a folder and file inherited from Linux, the source of Android's kernel and its key structures: /proc/net.

    In a commit at Android Open Source, Google's Jeffrey Vander Stoep launched the apparently-prosaic process of “locking down /proc/net”.

    Android Things is Google's managed OS that enables you to build and maintain Internet of Things devices at scale. We provide a robust platform that does the heavy lifting with certified hardware, rich developer APIs, and secure managed software updates using Google's back-end infrastructure, so you can focus on building your product.

    After a developer preview with over 100,000 SDK downloads, we're releasing Android Things 1.0 to developers today with long-term support for production devices. Developer feedback and engagement has been critical in our journey towards 1.0, and we are grateful to the over 10,000 developers who have provided us feedback through the issue tracker, at workshop events, and through our Google+ community.

  • Google Launches New Operating System “Android Things” For IoT Devices

    Google has tried to take some attention away from Build 2018 by releasing Android Things 1.0 – an operating system specially designed for Internet of Things (IoT) devices.

  • Things Gateway - the Virtual Weather Station Code

    The Virtual Weather Station was written using Things Framework, a new communication protocol to connect devices with controllers based on Web technology. The Things Framework consists of a set libraries and modules written in various languages. Each library implements a server that offers the Web Thing API on behalf of the device running the server. The protocol is HTTP, so the server offers a Web interface by embedding a Web Server. That interface contains all the mechanisms to query or control the device and is, therefore, the embodiment of the Web Thing API.

  • Google embraces, extends, and extinguishes

     

    What of Google’s role as a participant in open source? Sure, they make a lot of software open source, but they don’t collaborate with anyone. They forked from WebKit to get Apple out of the picture, and contributing to Chromium as a non-Googler is notoriously difficult. Android is the same story - open source in principle, but non-Googler AOSP contributors bemoan their awful approach to external patches. It took Google over a decade to start making headway on upstreaming their Linux patches for Android, too. Google writes papers about AI, presumably to incentivize their academics with recognition for their work. This is great until you notice that the crucial piece, the trained models, is always absent.

  • Linux Containers [Crostini] For Samsung Chromebook Plus In The Works

    Linux container development continues to plow forward with each day that goes by. More feverish than the entire Android app initiative for Chrome OS ever was, the Crostini project seems to introduce new features into the fold on what seems like a daily basis.

    If you haven’t kept up to date with all that is going on with Linux containers on Chromebooks, you can click here to read all we’ve written on the matter and get caught up with the latest info to date.

    Now that we’re on the same page, there’s a wrinkle in this whole development cycle we’ve known was coming. Dating back years, Linux support has always been better and more-supported on Intel-based devices. As we are seeing more ARM devices in the works (especially one being made with the powerful Snapdragon 845), we can’t forget about the existing devices that are currently out in the market.

  • Windows 10 April 2018 Update Hitting BSODs with CRITICAL_PROCESS_DIED Error

    We’re seeing an increasing number of reports pointing to BSODs experienced after upgrading Windows 10 devices to April 2018 Update (version 1803), and one of the most common stop codes appears to be CRITICAL_PROCESS_DIED.
    Judging from user reports online, the said BSOD happens on a wide variety of hardware configurations and the error appears to be triggered by different tasks, like launching apps, such as Skype, browsing the web, playing games, or watching videos.

    At this point, there doesn’t seem to be a specific pattern that would help reproduce the bug, but some users on reddit speculate that the BSOD might be caused by the GPU. Some believe it’s a driver compatibility issue, though by the looks of things, reinstalling the drivers doesn’t make any difference.

    Originally created by Google, Swift for TensorFlow gives developers "the power of TensorFlow directly integrated into the Swift programming language."

    According to the project page, which is hosted on Github, "We believe that machine learning tools are so important that they deserve a first-class language and a compiler."

  • Google open sources Seurat, a tool for reducing mobile VR complexity

    This launch arrives alongside the release of the Mirage Solo, the first headset on the Daydream VR platform to make use of Google’s WorldSense positional tracking system. The headset is standalone and runs on a mobile chipset so it’s a lot more resource-constrained than headsets that connect to gaming PCs.

    [...]

    In the snippet above from a new Blade Runner title, Google says the Seurat program was able to take a scene with 46.6 million triangles and reduce it down to 307,000. This is especially useful for developers with existing renders that they’re porting from more capable hardware to the more strained mobile VR hardware.

  • Google makes VR positional-tracking tool 'Seurat' open source on GitHub

    Technology companies have been telling us virtual reality will change the world for decades now. While VR has become more popular in recent years, it is still a niche market. Virtual reality will probably become mainstream in the future, but until prices come down even further, it will remain a hobby for enthusiasts.

    With that said, Google is still banking on virtual reality, especially with its Daydream initiative. Today, the search giant is making a VR positional-tracking tool called "Seurat" open source. The code is being hosted on GitHub.

So, earlier today Robby was showing me a Chromium commit that referenced enabling the Crostini UI by default on the Pixelbook. No surprise there as Google’s flagship has been the default testing ground for the Crostini Project and the implementation of Linux app containers for quite some time now.

Since the “Crostini” flag turned up on Chrome OS we have found multiple references to an actual menu item for the feature in the Chrome OS settings but until recently accessing the terminal app has only been possible through some hacking. Just last week, we saw the addition of the terminal app to the Chrome OS launcher but had yet to see Crostini’s front-facing UI in action.

  • Apache Cassandra at 10: Making a community believe in NoSQL
    Ten years ago this month, when Lehman Brothers was still just about in business and the term NoSQL wasn't even widely known, let alone an irritant, Facebook engineers open-sourced a distributed database system named Cassandra. Back then, the idea that huge numbers of companies would need a scalable database was almost laughable – and that grip of traditional relational database systems is reflected in the mythical moniker given to what would become one of the first of many databases designed to run on a cluster of machines. Named after the Greek figure who was cursed to utter the truth but was never believed, Cassandra might seem an odd choice for a system whose raison d'être is believability – but it delivered a nice dig at the stalwarts of the RDBMS world… and their trust in a false Oracle.
  • Google Launches Jib, Automated Container Packaging for Java Apps
    Google has released software that could automate the packaging of a Java program so that it can be run in the cloud-native environment.

Created over two decades ago at Sun Microsystems, Java was introduced as a “write once, run anywhere” programming language, where all the code would be packaged in a JAR file, and run by a Java Virtual Machine on any platform. The requirements for running code anywhere have expanded with the introduction of containerization, however. Few shops are Java-only these days, and many are turning to containerization for true application portability,

The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.
  • Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer
    Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events. At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.

    While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially. This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.

DistroWatch The Best Website For Distro Hoppers
