  • Play SNES SPC audio files from your browser using original hardware and Arduino | Arduino Blog

    Listening to those classic 16-bit sounds from the ’90s video game era brings back a wave of nostalgia for those who grew up with a console. On the Super Nintendo Entertainment System, outputting sound was accomplished by an integrated circuit called the SNES Audio Processing Unit (APU for short), which was responsible for taking SNES SPC files and transforming them into waveforms. Mauri Mustonen — who goes by Kazooie on YouTube — wanted to isolate this chip to play authentic music from his favorite tracks on his browser without needing to boot up the entire SNES console.

    The system he came up with has an Arduino Micro at its heart that is connected to the SNES APU via series of wires. Some of these links are for putting the APU into read or write mode, while others set the desired port and address for where the song data should be written. Data is sent or received over a set of eight parallel data lines.

  • PICO DSP is an Arduino compatible ESP32 development board for audio and DSP applications (Crowdfunding)

    ESP32 audio development boards have been around ever since ESP32 boards were introduced starting with Espressif Systems’ own “ESP32-LyraTD-MSC Audio Mic HDK“, and now ESP32 hardware and software have been certified for Amazon Alexa Voice Services.

    PICO DSP is another ESP32 development board for audio and digital signage processing (DSP) applications. Equipped with a Wolfson WM9878 stereo audio codec, the breadboard-friendly, Arduino compatible board includes two MEMS microphones, audio in and out jacks, a speaker header, plus other audio signals routed to a GPIO header.

  • Compact H.265 4K video encoder is made for embedded, medical, and military applications - CNX Software

    US-based Z3 Technology has announced the Z3-Q603-RPS, a compact H.265 video encoder system capable of supporting 4K and HD resolutions for embedded, medical, and even military camera applications through NDAA (National Defense Authorisation Act) compliance.

    The board runs Linux on Qualcomm QCS603 IoT processor for AI and computer vision applications, which we previously found in Microsoft’s Vision AI Developer Kit, supports Ethernet and WiFI 5 connectivity, as well as features such as PTZ (Pan Tilt Zoom).

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.
