  • Thousands Of Internet-Connected Satellites Above Us, What Could Possibly Go Wrong!

    Our skies are full of satellites, more full than they have been, that is, because SpaceX’s Starlink and a bevvy of other soon-to-launch operators plan to fill them with thousands of small low-earth-orbit craft to blanket the Earth with satellite Internet coverage. Astronomers are horrified at such an assault on their clear skies, space-watchers are fascinated by the latest developments, and in some quarters they’re causing a bit of concern about the security risk they might present. With a lot of regrettable overuse use of the word “hacker”, the concern is that such a large number of craft in the heavens might present an irresistible target for bad actors, who would proceed to steer them into each other can cause chaos.

    [...]

    Decades ago, to be involved in space technology you had to be a government. The average Joe might just be able to listen to some satellite traffic, but the investment required to set up any kind of ground station was not in any way trivial. Thus satellites were not built with security in mind because it was deemed unlikely that anyone would have the means to access them. This led to many craft carrying open transponders, making them effectively always-on analogue repeaters in the sky.

    As technology progressed it became possible to build or acquire ground station components for some of these transponders, and by the 1980s there were tales of shady companies selling transatlantic data links using illicit narrow-bandwidth carriers hidden amid the wideband TV feeds on commercial relays. This type of open-transponder hijack reached a mass-market in Brazil, where the US Navy’s Fleet Satellite Communications System dating from the late 1970s became so widely used as to become almost akin to a CB radio for the vast interior of that country. Even as satellite communications moved into the digital domain it was believed that the high barrier to entry would be enough of a deterrent, so for example the Iridium satellite phone system launched in the 1990s lacked encryption and could easily be eavesdropped upon with an SDR in 2015.

    In 2020 though, even the most novice of satellite engineers will be aware of security, and we expect that the likes of SpaceX will not have employed novices. Just as you could steal a 1980s Cosworth Ford Sierra with rudimentary tools but their latest quick Mondeo model has a formidable engine immobiliser built-in, so is it likely to be no walk in the park to compromise any of the current crop of spacecraft. Their citing a satellite hijack story from 1999 as reason to be worried in 2020 is about as valid as worrying about the Mondeo because a child could nick the Sierra; it simply isn’t credible. It’s not that there are not legitimate concerns to be expressed with relation to satellite security, it is simply that inflamatory and shoddy journalism is hardly the way to approach them.

  • AIoT Has a Nice Ring To It

    The Artificial Intelligence of Things (AIoT) is a relatively new term for the evolution of a domain Wind River has been playing in for a very long time. If we think of many of the first applications of Artificial Intelligence in connected devices, it is adding autonomy to previously human controlled systems. Think advanced autonomous drones, automated driver assistance features in vehicles, or even autonomous factory robots. These autonomous systems tend to still interact with humans, and as such they are safety critical. More so, they’re connected and have associated security risks. Importantly, you can have a secure device that doesn’t deliver safety critical functionality, but you cannot have an insecure safety critical device.

    These connected autonomous systems are incredibly complex, and require an intelligent systems platform from the device edge to the infrastructure edge to the cloud; and in the device they require real-time operating systems (RTOS) with guaranteed performance, coupled with AI/ML algorithms that are mostly associated with Linux. The use cases and requirements span the complete system. The systems may require containerized applications running in the cloud and on edge devices. The systems may require AI/ML frameworks that span the RTOS and Linux on the device. Wind River can offer the complete package with its comprehensive software portfolio.

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.
