  • Open Source Processors for Next-Generation Storage Controllers

    So, the agenda for the presentation is introduction to storage controller SoC devices, explanation of the typical flash control implementations requirements for the embedded CPU cores. And then our RISC-V SweRV Cores roadmap. And we'll go through use cases, such as acceleration of legacy code, software and firmware toolchain support; multithreading; and IPC improvements. Ultra-low interrupt latency, and our small EL2 cores targeting hardware accelerators. So, typical storage controller SoC device, what it needs to do is to provide a familiar SATA, SAS or NVM Express interface to the host and actually manage the persistent media present in a device. But it could also be a magnetic media or some of the new media, such as phase-change memory or NVRAM. The requirements on a controller are, in any particular order, reliability because, obviously, storage customer expects the no loss of data and expects high reliability of storing the files; security, such as boot from our security features that guarantee that firmware is not compromised; and data rest protection, which encrypts data in real time; performance, in case of SSDs, consumers expect high IOPS, high data rates; and, finally, power because shift to mobile devices require saving or shaving every watt. And same as in the data center, there's no difference.

  • Zamir SUN: Notes for beginning with STM32 - English

    Two years ago, when I was working on my first Home Automation, I start to think that I should learn some embedded development. However I have been too busy (well, I know this is an execuse) and haven’t really do anything meanful till recently.

    So when one of my friends asking if I can provide some information about embedded development recently, I start to think about this seriously. At this point, although I don’t have any experience with embedded development, I am not really a total newbie in this area. Inspired by The Best and Worst MCU SDKs, I decide to find the answer by first define some criteria from a newbie perspective, just to make it useful for my friends. Warning, this article is VERY SUBJECTIVE!

  • Arduino Blog » This digital clock uses 24 Arduino-controlled analog faces

    After being inspired by a beautiful, if rather expensive timepiece, Ira Hart decided to make a 3D-printed clock with 24 analog faces that combine to form a single digital display. The overall device is controlled by a single Arduino Nano, which keeps track of the time using a RTC module. This unit coordinates 24 other Nanos on custom carrier boards, which in turn drive their own little clock face via a pair of steppers and a gear system.

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.
