  • Bootlin toolchains updated, 2021.11 release - Bootlin's blog

    Bootlin has been offering since 2017 a large set of ready to use pre-compiled cross-compilation toolchains at toolchains.bootlin.com. These toolchains are available for a wide range of CPU architectures and CPU variants, and support either the glibc, uClibc-ng or musl C libraries, where applicable.

    It’s been quite some time since the last release of those toolchains, so we took the opportunity of this quiet period between Christmas and New Year to finally update the toolchains. We’re happy to announce that we have now published a total of 187 toolchains targeting 46 different CPU architecture variants. As the toolchain release name suggests, they are now built with Buildroot 2021.11.

  • Excellent Free Tutorials to Learn Coq - LinuxLinks

    Coq is a dependently typed language. This means that the types of the language may depend on the values of variables. In this respect, it is similar to other related languages such as Agda, Idris, F*, Lean, and others.

  • Experts Detail Logging Tool of DanderSpritz Framework Used by Equation Group Hackers

    Cybersecurity researchers have offered a detailed glimpse into a system called DoubleFeature that's dedicated to logging the different stages of post-exploitation stemming from the deployment of DanderSpritz, a full-featured malware framework used by the Equation Group.

    DanderSpritz came to light on April 14, 2017, when a hacking group known as the Shadow Brokers leaked the exploit tool, among others, under a dispatch titled "Lost in Translation." Also included in the leaks was EternalBlue, a cyberattack exploit developed by the U.S. National Security Agency (NSA) that enabled threat actors to carry out the NotPetya ransomware attack on unpatched Windows computers.

  • DragonFlyBSD Now Has Working Support For Intel Whiskey Lake Graphics - Phoronix

    The BSDs continue to lag behind Linux when it comes to the graphics driver support, but this time the Intel Whiskey Lake graphics should have been in long ago -- and believed to be -- but adding the PCI IDs were forgotten.

    Back in December of 2020 was a syncing of the Intel graphics driver PCI IDs from Linux 5.8 into the DragonFlyBSD kernel at the time. It should have been a straight-forward update for expanding the support given the commonality of the Intel Gen9 graphics at the time and DragonFlyBSD routinely porting over code from Intel's i915 Linux kernel graphics driver. Last year's commit was intended to bring support for Coffee Lake, Amber Lake, Whiskey Lake, and Comet Lake graphics on Intel processors. Unfortunately, the Whiskey Lake PCI IDs didn't end up being added to the driver list at the time.
