  • 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.

  • Montreal Subway Foot Traffic Data

    STM kindly sent me daily values for each subway stations from 2001 to 2018. Armed with all this data, I decided to play a little with R and came up with some interesting graphs. Behold this semi-interactive map of Montreal's subway! By clicking on a subway station, you'll be redirected to a graph of the station's foot traffic.

  • 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.

Apache Rya matures open source triple store database

The open source Apache Rya database effort is continuing to move forward as it reaches a new level of project maturity and acceptance. Rya (pronounced "ree-uh") is an RDF (resource description framework) triple store database. The project started at the U.S. government's Laboratory for Telecommunication Sciences with an initial research paper published in 2012. The project joined the Apache Software Foundation (ASF) in 2015 as an incubated project, and in September 2019 achieved what is known as Top-Level Project status. The Top-Level status is an indication and validation of the project's maturity, code quality and community. The ASF is home to Hadoop, Spark and other widely used database and data management programs.

The Spectre Mitigation Impact For Intel Ice Lake With Core i7-1065G7

For those wondering if -- or how much -- of a performance impact mitigations still make regarding Spectre for Intel's long-awaited 10nm+ Ice Lake processors, here is the rundown on the mitigation state and the performance impact. One of the areas that Phoronix readers have requested testing on with the recent purchase of the Dell XPS 7390 with Core i7 1065G7 is regarding the mitigation state and performance. Ice Lake with its Sunny Cove microarchitecture -- similar to Cascade Lake -- is no longer affected by Meltdown, MDS, or L1TF / Foreshadow. Read more

Networking SBCs run Linux on quad -A53 and -A72 NXP LS chips

Forlinx’s sandwich-style OK1043A-C and OK1046A SBCs run Linux on NXP’s quad -A53 LS1043A and quad -A72 LS1046A SoCs, respectively, and offer a 10GbE port and up to 6x GbE ports with optional SFP. Forlinx has posted product pages for two similar COM Express modules and carrier boards that run Linux on NXP’s networking focused LS series processors. The FET1043A-C module taps the up to 1.6GHz, quad-core, Cortex-A53 LS1043A while the FET1046A-C uses the up to 1.8GHz, quad-core, Cortex-A72 LS1046A. All the processors are headless — without GPUs.
