If the script requires such a resource or calculation, this synchronous behavior results in an error. This blocks all other processes in the queue from running whether or not they were dependent on the step that produced the error.

Intel’s 10th Gen CPUs recently showed up on several new systems including a v2 respin of Purism’s Librem Mini mini-PC, Sintrones’ EBOX-7010 upgrade of its earlier 9th Gen EBOX-7000 AI box, and Portwell’s 2.5GbE enabled WADE-8212 Mini-ITX SBC.
