  • Please welcome The 8472 and Ashley Mannix to Library Contributors

    Ashley Mannix maintains several popular Rust crates and used to be a part of the Library (API) Team. Ashley is now getting back into Rust open source work, and will be helping out with maintenance of the standard library and some official rust-lang crates such as log.

  • A dream resyntaxed

    When I read Curtis’s post I almost decided to bin this one, as he managed to cover everything necessary in his usual succinct, eloquent, and engaging style. But he has encouraged me to post my version of this discussion too, as it provides a little more detail on some of the issues we’re addressing, and on the design rationale for the changes we are jointly proposing.

    Personally, I always relish the opportunity to read two versions of exactly the same story by two very different authors, or to watch two directors’ very different takes on the same screenplay. In fact, that’s what initially attracted me away from SmallTalk/C++/Eiffel and into Perl: I read Larry’s version of “Object Orientation”, and found it much more entertaining, and also more enlightening than the other earlier interpretations.

  • GCC Patches Pending For RISC-V's Scalar Cryptography Extension - Phoronix

    Patches were recently sent out that implement support for RISC-V's Scalar Cryptography Extension within the GNU Compiler Collection.

    The RISC-V Scalar Cryptography Extension work recently wrapped up its public review period for the set of instructions proposed for this open-source processor ISA. The set of extensions aim to enhance RISC-V's capabilities for crypto workloads with AES encryption/decryption, SM4 and SM4 cipher instructions, an entropy source extension, bit manipulation instructions for crypto, carry-less multiply, and more.

  • Drew DeVault's blog: Status update, November 2021

    In other news, we have decided to delay the release of our new programming language, perhaps by as much as a year. We were aiming for February ‘22, but slow progress on some key areas such as cryptography and the self-hosting compiler, plus the looming necessity of the full-scale acceptance testing of the whole language and standard library, compound to make us unsure about meeting the original release plans. However, progress is slow but moving. We have incorporated the first parts of AES support in our cryptography library, and ported the language to FreeBSD. A good start on date/time support has been under development and I’m pretty optimistic about the API design we’ve come up with. Things are looking good, but it will take longer than expected.

  • Haskell Gemini server framework

    I'm in the process of building a Gemini server framework for Haskell. I know that one already exists (which has very heavily influenced mine) but mine doesn't need to be linked against OpenSSL, which is not hard to do, bit the process is inconsistent from OS to OS. I wanted something that was pure Haskell.

    It's not completed yet, but I welcome any feedback. I'm also livestreaming the coding process when I do work on it. I can supply information on that too if there's interest.

  • API Stability is No Black Magic!

    You might be surprised how much time R&D teams spend on fixing breaking APIs. Imagine you are the Head of Product, and your R&D team just finished a ground-breaking product after two years of software development. You are ramping up and fine-tuning the production with various global variants for six months to crank out that new product in volumes. Shipping large quantities of products, you get customer feedback that you haven’t received before, and you ask your R&D team to improve the software. Now the R&D team tells you that - instead of only fixing the customer issue - the team also needs to fix the APIs of the product because the latest release of the cross-platform UI toolkit broke several of the APIs you are using. Instead of spending a few days to the customer's issue, your team spends weeks updating everything, including API documentation and integration tests. Does this sound like an unrealistic scenario?

  • C++ Global Variables

    The concept of global variables plays a very vital role in C++ programming. It lets us use a variable anywhere within our whole program and change its values as per our requirements. The cause behind writing this guide is to introduce you to the concept of global variables in C++. After doing that, we also want to share with you some examples through which you will be able to understand the usage of global variables in C++ in Ubuntu 20.04 very clearly.

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.
