  • Raspberry Pi based audio DAC board starts at $225

    Orchard Audio’s $225 “PecanPi” audio DAC add-on for the Raspberry Pi and $400, Pi-equipped “Streamer” system features 24-bit, 192kHz sampling, 130dB SNR, and -110dB THD+N.

    Orchard Audio has opened pre-orders on a next-gen PecanPi audio DAC board for the Raspberry Pi that replaces its earlier, Kickstarter backed ApplePi DAC. The $225 PecanPi DAC offers modest audio improvements, as well as more options that can be be added a la carte all the way up to a $400 PecanPi Streamer system with aluminum case and Raspberry Pi. Shipments are expected between June and August.

  • 3.5-inch i.MX8M SBC focuses on A/V

    Seco’s 3.5-inch “SBC-C20” runs Linux on a dual- or quad-core -A53 i.MX8M SoC with up to 2GB RAM and 16GB eMMC plus 4K-ready eDP or HDMI 2.0, M.2 expansion, and optional -40 to 85°C.

    The SBC-C20 is the third and final SBC announced by Seco at Embedded World. It’s not as fast as the i.MX8 QuadMax based SBC-C43 and not quite as customizable as the i.MX8M Mini powered SBC-C61, but considering the widespread availability of the well-traveled i.MX8M, it’s likely to ship sooner than its siblings. The media-rich, 3.5-inch SBC targets “cost-effective solutions in the multimedia field as well as for IIoT applications.”

  • The path to Ubuntu Core

    At Canonical, helping customers overcome their challenges is what we do every day. In the IoT world, a common challenge we encounter is customers who are interested in transitioning to Ubuntu Core and the snapcraft.io ecosystem, but are unsure how to begin. This post covers the recommended approach.

    In most cases, it’s relatively easy for someone to see the advantages of Ubuntu Core when they’re first introduced to it. The transactional updates, immutable system design, simplified development and powerful update controls have most people going “you had me at transactional!”

    However, we all know the devil’s in the details. Shortly after the “eureka!” moment, there is often an anticlimax, as the newly minted Ubuntu Core believer starts to consider their current product state. For teams of harried software developers on a fixed budget, both in terms of time and money, making changes to the underlying components can feel impossible. Staring down the barrel of one or more projects with aggressive delivery schedules, the last thing you want to do is start changing things. To borrow from a quote often attributed to Walt Kelly, updating your device OS and packaging platform can feel like an “insurmountable opportunity.”

  • 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.
