[$] HTTPS certificates in the age of quantum computing

There has been ongoing discussion in the Internet Engineering Task Force (IETF) about how to protect internet traffic against future quantum computers. So far, that work has focused on key exchange as the most urgent problem; now, a new IETF working group is looking at adopting post-quantum cryptography for authentication and certificate transparency as well. The main challenge to doing so is the increased size of certificates — around 40 times larger. The techniques that the working group is investigating to reduce that overhead could have efficiency benefits for traditional certificates as well.

Ubuntu 26.04 With GNOME 50 Offering Some Performance Benefits For NVIDIA Linux Gaming

With GNOME 50 that is being used by default with the upcoming Ubuntu 26.04 LTS release, you may be curious about the out-of-the-box performance especially compared to prior Ubuntu Linux releases -- especially with Mutter 50 having some NVIDIA optimizations. In today's article is a first look at how the NVIDIA Linux gaming performance on Ubuntu 26.04 is looking compared to the current Ubuntu 25.10 release.

D7VK 1.5 Released With Direct3D 3 Now Implemented Over Vulkan

The open-source D7VK project began to implement Direct3D 7 over Vulkan similar to DXVK and VKD3D-Proton providing support for newer Direct3D APIs atop Vulkan. With succeeding releases D7VK was extended to Direct3D 6 too and then Direct3D 5 support. Now with today's D7VK 1.5 release, Direct3D 3 is implemented for faster acceleration using Vulkan...

Linux Patches Make The IPv6 Stack Less Modular To Lower Architectural Burden

Currently the Linux IPv6 networking stack can be built into the Linux kernel, built as a loadable kernel module, or not built at all. With proposed patches from a SUSE engineer, the IPv6 networking stack would be limited to being a kernel built-in or not at all. In doing away with IPv6 as a loadable kernel module would allow simplifying some code and lowering the Linux networking maintenance burden...

Arduino’s new Qualcomm-powered AI board ships with Ubuntu

Qualcomm subsidiary Arduino has announced the VENTUNO Q, a new single-board computer that ships with Ubuntu pre-installed. This isn’t a board aimed at casual makers or tech tinkerers bored with their Raspberry Pi, but catering to the demands of AI workloads at the edge: robotics, industrial automation, computer vision. The Ventuno Q is built around Qualcomm’s Dragonwing IQ-8275 processor with CPU, GPU and NPU, which delivers 40 TOPS of AI compute to run large language models, visual language models and computer vision workloads on-device. It comes with 16GB of LPDDR5 RAM – double what you get on the comparable Jetson Orin […]
