The turbostat utility is useful on Linux systems for reporting idle/power-state statistics, temperatures, and other useful metrics for modern CPUs. It's also able to dive deeper and provide various MSR values and counters and other intriguing CPU bits. For much of these features root access is required and thus turbostat has bailed out up to this point if not running as root. But as a number of the metrics can still be obtained without root access, turbostat is finally being adapted to handle running better as a non-root user...

Intel's FFmpeg Cartwheel is where they maintain their various yet-to-be-upstreamed patches for the FFmpeg multimedia library either to enhance/enable new Intel graphics hardware support or improve/add extra functionality to this widely-used open-source library.

Intel is using its Vision 2024 conference in Arizona today to announce the Gaudi 3 AI accelerator. With Gaudi 3 comes some rather bold AI claims from Intel: 50% on average better inference and 40% on average better power efficiency than the NVIDIA H100. All while costing "a fraction" of the NVIDIA H100. Gaudi 3 sounds quite promising and will be interesting to see how its adopted in the marketplace. In addition, Intel also is disclosing the new Xeon 6 branding for their upcoming server processors formerly codenamed Sierra Forest and Granite Rapids.

For confidential computing "CoCo" virtual machines where the VM host is assumed to be un-trusted and aims to be as isolated as possible, RdRand hardware random number generator instructions are one of the limited sources of entropy for guest VMs. Right now RdRand can fail and the CoCo guest VMs will continue to boot albeit with limited or no entropy to see the VM's random number generation. But being merged today as part of x86 fixes for Linux 6.9 is now requiring seeding RNG with RdRand for CoCo environments otherwise a kernel panic...
