I Added a Feature to OrcaSlicer to Show Travel Distance and Moves

OrcaSlicer is a powerful and popular slicer for 3D printers, known for its rich feature set and active development community. In this blog post, we’ll take a closer look at a new feature I proposed and implemented that provides more insight into your prints: the display of total travel distance and the number of travel moves. See the feat: Display travel distance and move count in G-code summary for more details.

How to Confirm Virtual to Physical Memory Mappings for PMem and FSDAX Files

Are you curious whether your application’s memory-mapped files are really using Intel Optane Persistent Memory (PMem), Compute Express Link (CXL) Non-Volatile Memory Modules (NV-CMM), or another DAX-enabled persistent memory device? Want to understand how virtual memory maps onto physical, non-volatile regions? Let’s use easily adaptable scripts in both Python and C to confirm this on your Linux system, definitively.

Why Does This Matter?

With the advent of persistent memory and DAX (Direct Access) filesystems, applications can memory-map files directly onto PMem, bypassing the traditional DRAM page cache. This promises significant performance and durability improvements for data-intensive workloads and databases, such as SQLite, Redis, and others.
