Security Leftovers

  • An Average IT Org

    Supply chain attacks are a known issue, and also lately there was a discussion around the relevance of reproducible builds. Looking in comparison at an average IT org doing something with the internet, I believe the pressing problem is neither supply chain attacks nor a lack of reproducible builds. The real problem is the amount of prefabricated binaries supplied by someone else, created in an unknown build environment with unknown tools, the average IT org requires to do anything. [...] Yes some of that is even non-free and might contain spyw^telemetry. [...] In the end the binary supply is like a drug for the user, and somehow the Debian project is also just another dealer / middle man in this setup. There are probably a lot of open questions to think about in that context. Are we the better dealer because we care about signed sources we retrieve from upstream and because we engage in reproducible build projects? Are our own means of distributing binaries any better than a binary download from github via https with a manual checksum verification, or the Debian repo at download.docker.com? Is the approach of the BSD/Gentoo ports, where you have to compile at least some software from source, the better one? Do I really want to know how some of the software is actually build?

For many websites, this feature can be a lifesaver but for some, there may involve some risks.

Open Hardware: Folding@Home ARM64 Linux Beta , Jetson, Arduino

  • Folding@Home ARM64 Linux Beta Release for COVID-19 Vaccine Research

    A few months ago, we reported that Rosetta@Home supported 64-bit Arm SBC’s and Servers in the Fight against COVID-19. But Folding@home did not support Arm hardware just yet, but thanks to work from Nercotix, Linaro, Arm, miniNodes, and Packet.com, we now get support for Foldering@home on ARM64 meaning you can help researchers studying SARS-CoV-2 virus and help them develop a COVID-19 vaccine with Raspberry Pi 3/4 boards, or other 64-bit Arm SBC’s and servers. The solution relies on Neocortix Cloud Services Platform allowing the unused capacity of large numbers of individual mobile phones or other connected nodes to be harnessed into a single, unified computational engine.

  • Xavier NX and Nano carriers include six-cam board and a dual Jetson system

    Auvidea has launched several carrier boards and systems for the Jetson Xavier NX and Nano: a JN34 with 6x FPD-Link III CSI-2 interfaces, JNX22 and JNX30 boards with PoE support, and a ES-JNX80/ES-J180 system for dual, mix-and-match Jetson modules. Back in February, we covered Auvidea’s JN30A and JN30B carriers for Nvidia’s Jetson TX1, TX2, and AGX Xavier along with some Jetson-powered boards from other vendors. Then in April, we posted a roundup of new Jetson Xavier NX carriers from D3, Diamond, and ConnectTech, Inc. In that story we mentioned some upcoming Auvidea Jetson carriers in passing. Auvidea has informed us that these and other boards are now available for order.

  • DIY Solar Powered LoRa Repeater (with Arduino)

Programming is done via a simple LCD screen on the front, along with three buttons.

Ubuntu MATE 20.04.1 for Raspberry Pi Now Has a Second Beta Ready for Testing

Martin Wimpress published a new beta version of the upcoming Ubuntu MATE 20.04.1 images for Raspberry Pi devices, which you can download and test right now on the tiny computer. Ubuntu MATE 20.04.1 for Raspberry Pi promises major new features, such as support for the latest Raspberry Pi 4 SCBs, better graphics, experimental USB booting, basic rendering for the Firefox web browser by default, support for the rpi-eeprom utility for updating the Raspberry Pi 4 bootloader EEPROM, and a new configuration tool. Based on the recently released Ubuntu 20.04.1 LTS (Focal Fossa) operating system, the upcoming Ubuntu MATE 20.04.1 for Raspberry Pi release is now in its latest stages of development, with a second beta version ready for public testing. Since beta 1, the team fixed Wi-Fi issues that occurred on the first boot during the initial setup wizard and dropped the gpu_mem memory option that lets you specify how much memory the GPU can use from the config.txt file for better performance. The beta 2 is also powered by the same Linux 5.4 LTS kernel used in Ubuntu 20.04.1 LTS, and uses the latest MATE 1.24 desktop environment and most the core apps that are also available in the Ubuntu MATE 20.04.1 LTS release for PCs.
