  • This low-cost motion control rig helps capture high-quality shots | Arduino Blog

    Being a camera operator is tough. Having to move the camera and maintain a smooth motion can be tricky, and the speed at which it’s done is never consistent. That’s what prompted Andy to create his own motorized robotic camera rig that can move in up to four different axes simultaneously. The camera gets attached to a standard mounting plate and then placed into the gimbal. The gimbal is able to both pitch the camera up (rotate around the X axis) and rotate it side to side (called ‘yaw’ or Z-axis rotation). In order to prevent a bunch of wires from tangling around each other while spinning, each rotational axis uses a slipring to transfer electrical power and signals continuously.

  • Arm announces first Armv9 cores, including powerhouse Cortex-X2

    Arm unveiled its first Armv9 cores: Cortex-X2 (16% faster than -X1), Cortex-A710 (10% faster than -A78), and Cortex-A510 (35% faster than -A55), all with at least twice the AI power of their predecessors.

    After announcing the Armv9 architecture in March, Arm has quickly followed up with the first three core IP designs based on it: the flagship, customizable Cortex-X2, as well as the “Big” Cortex-A710 and “Little” Cortex-A510. Arm skipped over the Cortex-A79 and -A56-59 naming schemes, perhaps to emphasize the fresh start with Armv9. Arm also announced a DSU-110 L3 bus follow-on to DynamIQ, which enables 8MB L3 on the Armv9 designs, as well as a high-end Mali-G710 GPU (see farther below).

  • Arm Announces The Cortex-X2 Armv9 Flagship CPU, Cortex-A710, Cortex-A510

    Arm today announced the Cortex-X2 as their new flagship Armv9 processor design. 

    The Cortex-X2 was announced by Arm this morning along with the Cortex-A510 as a new Armv9 "little" core design and the Cortex-A710 was also announced as the Cortex-A78 successor.

  • PC/104 boards keep the legacy alive with Quadro P1000 and Intel Braswell

    Adlink announced the “CM5-P1000,” the first PC/104 board equipped with Nvidia’s Quadro P1000 graphics. Meanwhile, ICOP has introduced a PC/104 form-factor “IBW-6954” SBC with an Intel Braswell CPU.

    Adlink and ICOP have each announced products that support the legacy PC/104 embedded board form factor and run Linux and Windows 10. Adlink’s CM5-P1000 is billed as the world’s first PC/104 board featuring Nvidia’s Quadro P1000, bringing advanced graphics and AI capabilities to legacy customers. ICOP’s IBW-6954 brings its customers somewhat up to date with an Intel Atom processor from the 6-year-old Braswell generation. ICOP chose Braswell because it is the last Intel platform that can support both UEFI and Legacy BIOS.

  • 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.
