  • Molly de Blanc: Autonomy and consent

    When I was an undergraduate, I took a course on medical ethics. The core takeaways from the class were that autonomy is necessary for consent, and consent is necessary for ethical action.

    There is a reciprocal relationship between autonomy and consent. We are autonomous creatures, we are self-governing. In being self-governing, we have the ability to consent, to give permission to others to interact with us in the ways we agree on. We can only really consent when we are self-governing, otherwise, it’s not proper consent. Consent also allows us to continue to be self-governing. By giving others permission, we are giving up some control, but doing so on our own terms.

    In order to actually consent, we have to grasp the situation we’re in, and as much about it as possible. Decision making needs to come from a place of understanding.

  • Ritesh Raj Sarraf: User Mode Linux 5.2

    User Mode Linux version 5.2 has been uploaded to Debian Unstable and will soon be available on the supported architectures. This upload took more time than usual as I ran into a build time failure caused by newer PCAP library.

    Thanks to active upstream developers, this got sorted out quick. In the longer run, we may have a much better fix for it.

  • Worn Out EMMC Chips Are Crippling Older Teslas

    Much like the rockets and spacecraft of sister company SpaceX, Tesla’s vehicles are powered by Linux running on what’s essentially off-the-shelf computing hardware. Until 2018 the Model S and X were running the open source operating system on a NVIDIA Tegra 3, at which point they switched the Media Control Unit (MCU) over to an Intel Atom solution. In either event, the Linux system is stored on an embedded Multi-Media Controller (eMMC) flash chip instead of a removable storage device as you might expect.

    Now under normal circumstances, this wouldn’t be an issue. There are literally billions of devices running Linux from an eMMC chip. But any competent embedded Linux developer would take the steps necessary to make sure the operating system’s various log files are not being written to a non-replaceable storage device soldered onto the board

    Unfortunately, for reasons that still remain somewhat unclear, the build of Linux running on the MCU is doing exactly that. What’s worse, Tesla’s graphical interface appears to be generating its own additional log messages. Despite the likelihood that nobody will ever actually read them, for every second a Tesla is driving down the road, more lines are being added to the log files.

    Now, it appears that the near continuous writing of data to the eMMC chips on the older Tegra-based MCUs has finally started to take its toll. Owners on Tesla forums are reporting that their MCUs are crashing and leaving the expensive vehicles in “Limp Home Mode”, which allows the car to remain drivable but unable to charge. The prescribed fix for this issue by Tesla is a complete MCU replacement at the cost of several thousand dollars. As this failure will almost certainly happen after the factory warranty has lapsed, the owner will have to foot the bill themselves.

  • Call of Duty: Modern Warfare ditches loot boxes for a battle pass

    Popularized by Fortnite, the battle pass system allows for players to buy the pass at the beginning of the season, and unlock a variety of items as they progress. Modern Warfare’s system sounds like it’ll be extremely similar to the Fortnite model (which has since been adopted by other major titles, like Destiny 2 and PUBG). Players will be able to buy a pass at the beginning of a season, with full transparency as to what the items included are, and how and when they’ll be unlocked.

  • Innr Smart White A19 bulb review: This inexpensive smart bulb seamlessly connects with a Philips Hue Bridge

    If you’re shopping for your first smart bulb and you’re not ready to invest in a hub, an Innr bulb isn’t the cheapest way to go. Instead, you’d be better off with a Bluetooth- or Wi-Fi-enabled bulb that can operate with just a smartphone app. The latest Philips Hue White bulb, for example, which can be controlled via Bluetooth as well as Zigbee), or a Wi-Fi-connected bulb like the $8 Wyze Bulb, which offers the bonus of being color-temperature-tunable.

  • The Untold Story of the 2018 Olympics Cyberattack, the Most Deceptive [Computer Attack] in History [iophk: Windows TCO]

    All nine of the Olympic staff's domain controllers, the powerful machines that governed which employee could access which computers in the network, had somehow been paralyzed, crippling the entire system. The staff decided on a temporary workaround: They set all the surviving servers that powered some basic services, such as Wi-Fi and the internet-linked TVs, to bypass the dead gatekeeper machines. By doing so, they managed to bring those bare-minimum systems back online just minutes before the end of the ceremony.

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.
