    Biden Sets Up Tech Showdown With ‘Right-to-Repair’ Rules for FTC

    While the agency will ultimately decide the size and scope of the order, the presidential right-to-repair directive is expected to mention mobile phone manufacturers and Department of Defense contractors as possible areas for regulation. Tech companies including Apple Inc. and Microsoft Corp. have imposed limits on who can repair broken consumer electronics like game consoles and mobile phones, which consumer advocates say increases repair costs.

  • Is NVMe faster than SSD? – Linux Hint

    There is much confusion about the terms NVMe and SSD. In some cases, they are mistaken as two different drives, and sometimes their speeds are even compared. NVMe and SSDs are two very other things, but they work in tandem for faster storage access and data processing. NVMe is a protocol, an architecture that efficiently drives SSDs to work with the PCIe interface for optimum performance, while SSD is the storage drive itself. It is therefore incorrect to compare the speeds of NVMe and SSD. NVMe is the technology behind NVMe SSD’s extremely fast speeds and lower latency.

    The better and more specific question would be “Is NVMe faster than SATA SSD?” to which the answer would be a flat YES. NVMe SSDs are about 3-4 times faster than SATA SSDs with read-write speeds of up to 2000MB/s compared to the only 600MB/s of SATA SSDs. Unlike SATA and SCSI, NVMe doesn’t need a controller to communicate with the CPU, making communication with the CPU even faster. NVMe uses four PCIe lanes, supports massive 64K queues, and can send 64K commands per queue. The NVMe protocol, however, requires only 13 commands for high performance.

    NVMe SSDs also achieve lower latency than SATA SSDs. An NVMe SSD’s data reading latency is 300 microseconds, while SATA SSD is 500 microseconds based on an actual test. Likewise, data writing for SATA SSD is 2 ms, while NVMe SSDs is only 1ms.[1] The differences seem negligible, but the differences are substantially evident when working on large volumes of data.

    SATA SSDs, however, still have a price advantage over NVMe SSDs. NVMe-based SSDs have a higher price tag than SATA SSDs, the reason why SSDs using older technologies are still widely used today. SATA SSD’s lower price is more practical for regular consumers who can settle for the modest speed that this type of SSDs offer.

  • Automate your home on the cheap with this Arduino setup | Arduino Blog

    All too often, those who are new to Arduino struggle with creating large projects due to a lack of experience and components. This can be frustrating, but Instructables user MAKE_IT WITH_ME decided to tackle this issue by designing a super cheap way to automate home circuitry from just a single Starter Kit. His build uses a single Arduino Uno, although it can easily be swapped with something like a Nano or Mega, along with a stepper motor/driver, servo motor, threaded rod, and an IR receiver + remote combo.

  • AGX Xavier edge AI system has four PoE ports

    Axiomtek unveiled a Jetson AGX Xavier based “AIE900-902-FL” computer with dual lockable HDMI ports and 6x GbE, 4x of which offer PoE. There is also a more compact, Whiskey Lake based “eBOX565” box.

    Axiomtek has announced the AIE900-902-FL, its first computer based on Nvidia’s high-end Jetson AGX Xavier. There is also a much smaller, Whiskey Lake based eBOX565 system that is a minor variation of an earlier eBOX (see farther below).

    The AIE900-902-FL follows earlier Jetson-based products such as the smaller AIE100-903-FL-NX, which similarly runs Linux on the lower-end Jetson Xavier NX. The system is designed for edge AI applications including 3D vision guided robots, autonomous mobile robots (AMRs), intelligent video analytics, domain-focused robot assistant, and intelligent roadside units.

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.
