New project uses rollups to build Linux-based decentralized computer

Filed under
GNU
Linux

Layer-two project Cartesi has unveiled a rollup-centric design for its Cartesi Machine, a Linux-based virtual machine that would allow developers to run any type of computing application secured via blockchains.

Cartesi’s design uses a slightly modified version of Optimistic Rollups, a layer-two technology developed within the Ethereum ecosystem, to power its virtual machine. In contrast with Optimism’s implementation, which uses this type of rollups primarily to maintain full compatibility with Ethereum smart contracts, Cartesi wants to offer a traditional development environment.

The Cartesi virtual machine emulates a RISC-V microprocessor architecture, an open-source alternative to the ARM instruction set commonly used in smartphones or Apple’s M1-based computers. The RISC-V architecture allows running standard software environments based on Linux. For developers building on Cartesi, this means that smart contracts can be developed in virtually any language and development ecosystem, provided it is supported by Linux.

Free Open Source GPU Under Development for RISC-V

  • Free Open Source GPU Under Development for RISC-V

    The days of open-source GPUs may soon be upon us. The RISC-V architecture enables small companies to develop purpose-built processors and microcontrollers without paying a royalty. There are numerous free and commercial IP building blocks for RISC-V-based system-on-chips (SoCs), but the portfolio lacks a graphics option. This will change in a few years as a group of enthusiasts has started developing an open-source GPU based on the RISC-V architecture.

    At this point, there are no plans to compete against AMD, Arm, Imagination, and Nvidia in the foreseeable future. Instead, the group plans to develop a scalable fused CPU-GPU ISA that could scale from simplistic microcontrollers all the way to advanced GPUs supporting ray tracing, machine learning, and computer vision applications with custom hardware extensions.

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.
