  • The Future of Linux DApps – Cartesi Launches ‘Descartes’ SDK Documentation Portal

    The Descartes SDK makes it possible for developers to build computationally intensive DApps with all software tools available for a full Linux operating system. DApps preserve full decentralization and the security guarantees of Ethereum.

    Developers and software enthusiasts can access the Documentation Portal immediately through Cartesi’s redesigned website. The portal provides tutorials and the information developers need to get started at coding for Cartesi.

  • AMD/ROCm "AOMP" Compiler Enables OpenMP 5.0 By Default, Preps For More Upstreaming

    AOMP 11.6-2 is out this evening as the final Radeon Open Compute update for H1'2020. This is AMD's LLVM Clang downstream focused on providing OpenMP offloading to Radeon GPUs.

    AOMP is ROCm's OpenMP focused compiler based on Clang that launched with ROCm 3.0 at the tail end of last year. Since then AOMP releases have come fairly frequently and AMD has been working to upstream the code where possible/relevant into upstream LLVM/Clang.

  • Some updates: CapTP in progress, Datashards, chiptune experiments, etc

    Hello... just figured I'd give a fairly brief update. Since I wrote my last post I've been working hard towards the distributed programming stuff in Goblins.

    In general, this involves implementing a protocol called CapTP, which is fairly obscure... the idea is generally to apply the same "object capability security" concept that Goblins already follows but on a networked protocol level. Probably the most prominent other implementation of CapTP right now is being done by the Agoric folks, captp.js. I've been in communication with them... could we achieve interoperability between our implementations? It could be cool, but it's too early to tell. Anyway it's one of those technical areas that's so obscure that I decided to document my progress on the cap-talk mailing list, but that's becoming the length of a small novel... so I guess, beware before you try to read that whole thing. I'm far enough along where the main things work, but not quite everything (CapTP supports such wild things as distributed garbage collection...!!!!)

    Anyway, in general I don't think that people get too excited by hearing "backend progress is happening"; I believe that implementing CapTP is even more important than standardizing ActivityPub was in the long run of my life work, but I also am well aware that in general people (including myself!) understand best by seeing an interesting demonstration. So, I do plan another networked demo, akin to the time-travel Terminal Phase demo, but I'm not sure just how fancy it will be (yet). I think I'll have more things to show on that front in 1-2 months.

  • Top 5 programming languages for systems admins to learn

    You may be asking yourself, why write an article about something you don't like? There's a simple answer for that, too. It makes the systems admin portion of my job responsibilities significantly easier. That's the main reason I work so hard at figuring it out, making sense of it, taking courses, and ultimately putting it to good use. There aren't enough hours in the day to give everything that personal touch or to repeat the same task over and over across tens of thousands of clients, servers, and mobile devices on- and off-site.

    As a hands-on IT professional, I can be found working on many jobs at once, attending meetings, and providing support to colleagues at any given time. So, that's why learning at least one programming language is so important: The flexibility of automating tasks (particularly the repetitive ones) frees up time that is better spent addressing matters that require the personal touch.

  • Thinking and Question of The Proposal for Perl 7 - day1

    First of all, I am wondering about this assumption.

    This is because there are very few incompatible API changes in Perl's history (Perl 1, 2, 3, 4, 5).

    If the Python developers are thinking this way, it makes sense.

    Has Perl ever thought of this in history?

    Perhaps Perl has kept the maximum backward compatibility even in the major version upgrade?

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.
