Mesa CI Optimization Could Provide Big Bandwidth Savings

Phoronix - Fri, 07/03/2020 - 19:16
You may recall that earlier this year X.Org/FreeDesktop.org may have to cut CI services for developers over the cloud expenses associated with that continuous integration service for the likes of Mesa, the X.Org Server, and other components.

I use LEGO CAD to document some of my own creations (or "MOCs," as custom sets are called in some digital LEGO communities). The advantage of computer-aided design (CAD) is precision. When you use CAD to build something in virtual space, you can reasonably expect that it can be built in the real world. While the LEGO CAD applications I use don't have simulated physics to verify the structural integrity of my designs, I do lay every brick in the software to mimic a model I've made in real life.
