  • 'Pwnagotchi' Is the Open Source Handheld That Eats Wi-Fi Handshakes

    Ever wondered what would manifest if you mixed 1990s nostalgia with a clever name and some futuristic hacking tech?

    The answer is the Pwnagotchi: a DIY, open source gadget for hacking Wi-Fi that gets smarter the more networks it gets exposed to using machine learning. It also has an adorable interface that reflects different "moods" depending on what it's doing, and echoes the Tamagotchi digital pets of the 90s. The idea is for its user to take it around the city and "feed" it with Wi-Fi handshakes, the process that allows phones or laptops to communicate with other wireless devices like a router or a smart TV.

    In theory, these handshakes can then be cracked to reveal the Wi-Fi network’s password, which would be useful if the Pwnagotchi user wanted to hack into the Wi-Fi network at a later time.

    [...]

    To run the software, all you need is a Raspberry Pi Zero W, a microSD card with at least 8 GB of storage, and an external battery. If you want to see the Pwnagotchi’s cute black and white emoji face, you’ll also need a 2-inch e-paper display, according to the project’s official page. That amounts to a $60 investment, give or take, at the time of publication.

  • ARM responds to open source challenge, allowing user-defined instructions

    It is not just the network hardware and software that are opening up, sometimes painfully, after years of proprietary systems. Even at chip level, there are pressures to open up the architectures, with open source initiatives targeting processors (as with RISC-V) and even modems. This is prompting response from the semiconductor giants as they go through their own process of adapting to a cloud and 5G world. Intel has started to work closely with some open initiatives and to drive its interfaces as standards in areas like chiplets. Xilinx has announced an open software development platform to make its FPGAs more deployable and interoperable with other vendors’ components.

  • Alibaba Open-Sources Its MCU to Boost AI Research

    An MCU (Micro Controller Unit, aka microcontroller) is a chip-scale computer that integrates a CPU, RAM, ROM, timer, counter, and various I/O interfaces into a single chip. As a core component of embedded devices, MCUs are widely used in communications, consumer electronics, automotive electronics, and industrial control, and are the most in-demand chip type on the market.

    Most IoT (Internet of things) devices need to be equipped with next-generation MCU chips to perform complex tasks such as sensing, communication, information processing, calculation, and release of control commands. AI capabilities and cloud access capabilities are the most significant differences between next-generation MCU chips and traditional MCU chips.

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.
