Open Hardware: Purism, Arduino, and More

  • Internet of Snitches – Purism

    Imagine an Internet of Snitches, each scanning whatever data they have access to for evidence of crime. Beyond the OS itself, individual phone apps could start looking for contraband. Personal computers would follow their lead. Home network file servers could pore through photos, videos and file backups for CSAM and maybe even evidence of copyright infringement. Home routers could scan any unencrypted network traffic. Your voice assistant could use machine learning to decide when yelling in a household crosses the line into abuse. Your printer could analyze the documents and photos you send it.

    It’s not much of a surprise to most people that their devices, especially their phones, are snitching on them to the hardware vendor (or app developer). Some people are surprised to discover just how much. I already wrote a post Snitching on Phones That Snitch on You that focused on the amount of data an idle Android and iOS device are sending to Google and Apple respectively, described how we avoid those problems on the Librem 5, and even explained how to use OpenSnitch to track any attempts by a malicious app to snitch on you.

    So we know most devices and proprietary apps track people to some degree (even for paying customers), and that the problem has extended to cars. While many people don’t like the idea of this, they also shrug it off, not just because they don’t feel empowered to do much about it, but also because their data is “only” being used for marketing purposes. Someone is profiting off of the data, sure, but their data isn’t being used against them.

    Yet we are starting to see how your data can be used against you. Police routinely get location data from data brokers to track suspects without having to get a warrant. Even private groups have paid data brokers to dig up dirt on people, leading to a Catholic priest’s resignation after location data revealed he used the Grindr app and frequented gay bars.

  • Arduino development with fast and easy debugging from Segger

    Arduino has partnered with Segger to further support developers in creating their own embedded systems, implementing compatibility of Segger debugging solutions with Portenta boards.

    Debuggers are the scalpel that allows a developer to dissect any application code running on embedded hardware. This versatile tool helps the programmer to halt programs at specific points, inspect values stored in memory units, modify CPU registers and enter test data to narrow down on buggy pieces of code. This tool comes in handy when you want to locate malfunctioning code and fix faulty program execution.

  • Sharing Arduino Education courses is easier than ever | Arduino Blog

    Over the past few years, Arduino Education has expanded, offering new learning solutions to teachers and students around the world. Today, we have more than 10 kits with exciting online courses for STEM teachers and learners ranging from middle school to university.

    When creating these products, we were delighted to collaborate with many brilliant educators, who shared with us their unique teaching styles and provided valuable feedback.

    With the pandemic dramatically shaking up the status quo in education, we now have more learning styles than ever. From large schools using hundreds of Arduino kits to smaller classes and study groups. There are even a lot of parents who use kits for homeschooling, along with an increasing numbers of self-learners.

    We’re excited to see Arduino Education products being enjoyed in so many different ways, and want to make sure our kits are easy to use and share in every situation. That said, we’re excited to announce several changes to how our educational products are shared.

  • Intel’s Elkhart Lake powers three new thin Mini-ITX boards

    MiTac’s “PD10EHI,” DFI’s “EHL171/EHL173,” and ASRock’s ”IMB-1004” thin Mini-ITX boards extend Intel’s 10nm Atom x6000 with triple displays, USB 3.1 Gen2, SATA, M.2, and PCIe. DFI and ASRock also offer 2.5GbE.

    Earlier this week, ICP Germany announced a thin Mini-ITX PD10EHI board with Elkhart lake (Atom x6000, etc.) from its manufacturing partner MiTac, but the press release accidentally linked to a recently introduced, Comet Lake based PH12CMI thin Mini-ITX, which we covered. Now we are returning to the PD10EHI along with DFI’s EHL171/EHL173, which we similarly spotted on a preliminary holding page back in February when we reported on Advantech’s similarly Elkhart Lake based AIMB-218 thin Mini-ITX board. We have also uncovered an ASRock Industrial IMB-1004 board with the same combination, which we cover here.

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.
