  • Ubuntu Blog: Edge AI in a 5G world – part 2: Why make the cell tower smart?

    AI training & ML operationsDecades of Moore’s Law have given us smartphones at a price we’re willing to pay but IoT devices need to be much cheaper than that. Adding today’s fastest CPUs or GPUs to IoT devices costs a significant amount which put a hard limit on what the market is currently willing to buy at scale.

    The IoT devices that are currently on the market are usually underpowered and have limited connectivity. With 5G connectivity and shared compute resources at the Edge these constrained devices will soon be able to do much more.

    For instance, adding a GPU to each IoT device for the purposes of AI model inference would mean a significant increase in the hardware bill of materials. This cost would be passed onto the consumer and because it is more expensive would drastically reduce the target audience. Instead, 5G allows for heavy computation to be offloaded to nearby shared GPUs and get a response with minimal latency.

    We will dive into this approach in the next section.

  • Tech Giants Team Up to Launch Open Source 5G Infrastructure Management Tool

    “5G and Edge Computing industry initiatives will require large-scale and geographically distributed multi-vendor infrastructure deployments”

    HPE and Intel are working with open source partners such as Red Hat to create a 5G distributed infrastructure management tool that could potentially help telecommunications firms get past the difficulty of installing 5G system into sites that hold infrastructure belonging to multiple vendors.

    The project will be donated to the Linux Foundation, with release scheduled for later in Q2 2020. It will be accessible via: www.linuxfoundation.org.

  • Cloudflare announces free VPN tool WARP for Windows and macOS, with Linux to follow

    If you're in the market for a free VPN for your desktop PC or laptop, Cloudflare will soon have a new offering.

    Following on from the success of its free VPN for mobile devices, the company that's also behind the 1.1.1.1 DNS resolver is now bringing WARP to Windows and macOS -- and there is a Linux version in the works. Cloudflare's WARP is currently available in beta, but not everyone will be able to get access to it straight away.

  • Kubernetes 1.18 Feature Server-side Apply Beta 2

    Server-side Apply is an important effort to migrate “kubectl apply” to the apiserver. It was started in 2018 by the Apply working group.

    [...]

    Server-side Apply works by keeping track of which actor of the system has changed each field of an object. It does so by diffing all updates to objects, and recording all the fields that have changed as well the time of the operation. All this information is stored in the managedFields in the metadata of objects. Since objects can have many fields, this field can be quite large.

    When someone applies, we can then use the information stored within managedFields to report relevant conflicts and help the merge algorithm to do the right thing.

Cloudflare Launches Free VPN

  • Cloudflare Launches Free VPN for Windows and Mac, Linux Version Also Coming

    Cloudflare has released the first beta of WARP for Windows and Mac, one year after the application make its way to mobile devices.

    Available free of charge on the two platforms right now, WARP is supposed to make its way to Linux as well, but Cloudflare says additional work is required in this regard.

    The company promises WARP for Windows and macOS will graduate from beta faster than the mobile sibling did on Android and iOS – general availability for the mobile version was announced in September 2019 after the April debut of the beta.

10 Best Linux Font Tools (Updated 2020)

In the days when Linux was a fledgling operating system, font handling was often identified as a major weakness. It was true that Linux then had problems with dealing with TrueType fonts, its font subsystem was prehistoric compared to its competitors, there was a dearth of decent fonts, difficulties in adding and configuring fonts made it almost impossible for beginners to improve matters for themselves, and jagged fonts with no anti-aliasing just added to a rather amateurish looking desktop. Fortunately, the situation is considerably better these days, with a better quality of user interface typography. With the continuing improving FreeType font engine producing high quality output, natively supporting scalable font formats like TrueType, Linux is making great strides although there’s still some way to go. Dealing with fonts under Linux can sometimes be tricky. Read more

  • 3 Top Node.js Package Managers for Linux

    Node.js is one of the most popular programming languages rocking the software development industry in the world over. While developing and using Node.js applications, one common software that developers and general users will always find themselves relying on is a package manager. A Node.js package manager interacts with online package repositories (that contain Node.js libraries, applications, and related packages) and helps in many ways including package installation and dependency management. Some package managers also feature project management components.

  • Intel oneAPI DPC++ Compiler 2020-05 Released

    Intel has released oneAPI DPC++ Compiler 2020-05 as their latest snapshot for the current state of their LLVM-based Data Parallel C++ Compiler. Data Parallel C++ is Intel's cross-architecture language for direct programming that is derived from C++. DPC++ leverages Khronos' SYCL and the LLVM Clang compiler infrastructure so that the generated code in conjunction with the DPC++ run-time can run on hardware from CPUs to GPUs, FPGAs, and other specialized accelerators.

  • Testing in Go: philosophy and tools

    The Go programming language comes with tools for writing and running tests: the standard library's testing package, and the go test command to run test suites. Like the language itself, Go's philosophy for writing tests is minimalist: use the lightweight testing package along with helper functions written in plain Go. The idea is that tests are just code, and since a Go developer already knows how to write Go using its abstractions and types, there's no need to learn a quirky domain-specific language for writing tests.

  • Marco Zehe: My Journey To Ghost

    As I wrote in my last post, this blog has moved from WordPress to Ghost recently. Ghost is a modern publishing platform that focuses on the essentials. Unlike WordPress, it doesn‘t try to be the one-stop solution for every possible use case. Instead, it is a CMS geared towards bloggers, writers, and publishers of free and premium content. In other words, people like me. :-) After a lot of research, some pros and cons soul searching, and some experimentation, last week I decided to go through with the migration. This blog is hosted with the Ghost Foundation‘s Ghost(Pro) offering. So not only do I get excellent hosting, but my monthly fee will also be a donation to the foundation and help future development. They also take care of updates for me and that everything runs smoothly. And through a worldwide CDN, the site is now super fast no matter where my visitors come from.

  • he Glean SDK and iOS Application Extensions, or A Tale of Two Sandboxes

    Recently, I had the pleasure of working with our wonderful iOS developers here at Mozilla in instrumenting Lockwise, one of our iOS applications, with the Glean SDK. At this point, I’ve already helped integrate it with several other applications, all of which went pretty smoothly, and Lockwise for iOS held true to that. It wasn’t until later, when unexpected things started happening, that I realized something was amiss… [...] Well, that wasn’t ideal, to say the least, so we began an investigation to determine what course of action we should (or could) take. We went back and forth over the details but ultimately we determined that the Glean SDK shouldn’t know about processes and that there wasn’t much we could do aside from blocking it from running in the extensions and documenting the fact that it was up to the Glean SDK-using application to ensure that metrics were only collected by the main process application. I was a bit sad that there wasn’t much we could do to make the user-experience better for Glean SDK consumers, but sometimes you just can’t predict the challenges you will face when implementing a truly cross-platform thing. I still hold out hope that a way will open up to make this easier, but the lesson I learned from all of this is that sometimes you can’t win but it’s important to stick to the design and do the best you can.
