  • Game Boy Recreated in Verilog

    With the wide availability of Raspberry Pi hardware and pre-baked Linux distros with emulators ready to go, making a retro handheld is easier than ever. Emulation isn’t the only way to go about playing old games however. [Wenting Zhang] decided to instead recreate the Nintendo Game Boy in Verilog, and has documented the effort.

    The project runs on a Spartan 6 FPGA. [Wenting] first developed the hardware to use a DualShock controller for input, and output video to a regular LCD monitor. However, work is now underway to produce a handheld VerilogBoy. This will feature a 320×320 LCD screen, with pixels being quadrupled from the original Game Boy 160×144 resolution, with some pixels to spare. [Wenting] is also looking at porting the code to some Pano Logic units, which we’ve discussed before. The thin clients pack FPGA hardware and lots of IO ports that make them perfect for such a project.

  • OpenMV: Low-cost, open-source platform enables disparate embedded vision applications

    Making embedded machine vision applications more accessible is the ultimate goal of OpenMV, a project responsible for developing multiple iterations of open-source, low-cost embedded camera platforms.

    OpenMV began in 2013, when Ibrahim Abdelkader, Vice President and Co-Founder, sought a better, cheap serial camera module than what was available to him. The desired result was a small, expandable machine vision module that cost less than $100. Eventually, OpenMV moved to a Hackaday Project, then to a Kickstarter project, then—when Kwabena Agyeman, President and Co-Founder joined in 2015—an operating business.

    “With the kernel, you can send a script of Python code, and it parses, compiles, and executes that code. All our functions are written in C, then they have a Python module created for them that you can call using the MicroPython interpreter. The reason having Python is helpful is that our firmware is about 2 MB now, and it takes a good minute or so to load the firmware,” he says.

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.
