After fighting with the divide between implicit and explicit synchronization with Vulkan on Linux for over seven years, we may finally have some closure.

ARM-based computers continue to make inroads across both personal computing as well as cloud server spaces, from the ARM-based MacBooks you can use during development to the AWS Graviton2-based instances that provide better price-performance than similar Intel x86-based instances. But Amazon isn’t the only cloud provider with ARM-based instances. Oracle Cloud offers the Ampere Altra […]

sake is a CLI tool that enables you to run commands on servers via ssh. Think of it like make, you define servers and tasks in a config file and then run the tasks on the servers.

And 'tweaks' is doing some heavy lifting, there
