  • The (GNU) Linux Foundation How Fast it is Going, Who is Doing It, What They are Doing, and Who is Sponsoring It December 2010

    Every (GNU) Linux kernel is being developed by nearly 1,000 developers working for more than 100 different corporations. This is the foundation for the largest distributed software development project in the world. (src)

  • Sébastien Wilmet - Blog post - Thoughts about WebAssembly outside-the-browser, inside-the-desktop

    Some reflections about WebAssembly, the Bytecode Alliance and desktop application development.

    To know more about the Bytecode Alliance (WebAssembly outside-the-browser), you can read this nice article by Mozilla.

    Note that I don't plan to work on this, it's just some thoughts about what could the future bring us. If someone is interested, this would be a really, really nice project that would totally change the landscape of native desktop application development. I'm convinced that the solution isn't Rust or C++, or C# or Java, or whichever new language will appear in 20 years that will make Rust obsolete; the solution is some piece of infrastructure such as nanoprocesses.

  • Sébastien Wilmet - Blog post - C dialects versus C++ dialects

    Some developers say that since the C++ programming language is so large, containing lots of features, each C++ programmer ends up writing code in a different subset of C++, a different dialect.

    This essay looks at whether the C language - which contains a much smaller set of core features than C++ - is any better with regards to the "dialects problem".

  • Compute Like It Is 1975: 6th Edition Unix Reborn | Hackaday

    If you crave experiencing or reliving what computing was like “back then” you have a lot of options. One option, of course, is to load an emulator and pretend like you have the hardware and software you are interested in. Another often expensive option is to actually buy the hardware on the used market. However, [mit-pdos] has a different approach: port the 6th edition of Unix to RISC-V and use a modern CPU to run an old favorite operating system.

    It isn’t an exact copy, of course, but Xv6 was developed back in 2006 as a teaching operating system at MIT. You can find resources including links to the original Unix source code, commentary on the source code, and information about the original PDP 11/40 host computer on the project’s main page.

  • Recently launched MagicHub.io offers free datasets for machine learning

  • Intel's Cloud-Hypervisor Jumps From v0.14.1 To v15.0 To Signify Its Maturity, Stabilizing

    The Rust-written Cloud-Hypervisor project led by open-source Intel engineers as a VMM designed for cloud workloads has broke well past the "1.0" milestone. Following a series of 0.x releases, Cloud-Hypervisor 15 was released this week.

    The engineers involved in this open-source security and cloud minded hypervisor decided to shake up the version numbering. They went from v0.14.1 to v15.0 to "represent that we believe Cloud Hypervisor is maturing and entering a period of stability."

    Moving forward they now say they will guarantee API stability by not removing or changing APIs without at least two releases notice and point releases will also be issued for substantial bug fixes or security issues.

  • Ubuntu Blog: Taming unruly logo sections

    Making logo sections can be tricky. Logos come in all shapes and sizes, and without proper care, it is easy to end up with a poorly balanced layout.

    [...]

    With the baseline in place, we’d ideally want to scale the wordmarks to roughly the same height. To do this, we need to select a goal height to resize to – in the example above this is illustrated by the “Ag” letter pair.

    But this leads to a problem – depending on how tall our goal height is, some logos won’t fit, or others will become too small. At this point it’s an iterative process of adjusting the goal height until most logos fit comfortably within the bounding box.

    It’s worth noting that the longest wordmark isn’t always the best choice for goal height, as that would make other logos tiny. In my experience, it is best to find a size that works for the majority of the cases, and not worry about outliers too much.

    [...]

    As a final step, if the order of the logos is up to the designer (sometimes it might be dictated by the nature of the relationships with the companies behind these logos), we can further increase balance by introducing different rhythms – alternations of colors, narrow vs wide, rounded vs angular, etc.

  • Call for Code: The Weather Company and you

    Exhaustive scientific research has confirmed changing weather and temperature patterns, rapidly rising sea levels, and an intensifying proliferation of extreme weather events around the world. The frequency of these weather events continue to increase year after year. And the impact they have on people and the amount of damage they cause are escalating.

    Severe and devastating weather is not going away. It is only going to get worse, according to the National Climate Assessment. By the year 2100, global temperatures are projected to increase 3 to 5 degrees Celsius (5.4 to 9 degrees Fahrenheit).

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
