     * Slightly updated the [[guides:gpu|GPU guide]] to reflect this
   * [[https://mmm.s-ol.nu|s-ol bekic]] added support for [[https://git.s-ol.nu/forks/folk/-/tree/printer-config/|paginating long programs]] so they print on multiple pages! (as well as A4 support) [[https://github.com/FolkComputer/folk/issues/58|we've wanted this for a while]]
+  * s-ol made a lot of [[https://github.com/FolkComputer/folk-live-build/pull/4|improvements to the live USB setup.folk config file]], so you can set hostname and configure a printer
+    * Omar added persistence of calibration and printed programs, and fixed file permissions for git pull, so the live USB is totally usable as a long-term system now!
   * Omar did a cleanup of the repo, removing the pi/ and play/ folder (preparing for opening the repo more to the public)
     * Inlined hardware interface code into the virtual-programs -- should make it much easier to read since all GPU stuff is in one file, all AprilTag stuff is in one file, all camera stuff is in one file, etc

   * Omar has been working a bit on the portable gadget from last month
     * Got a good hand grip, working on and off on CAD for enclosure (need to fit Pi, Pi camera, threaded inserts for hand grip and projector, and be able to physically fit my hand in to assemble all of it; think I need to break it up into panels)

 Omar finished porting [[https://owentrueblood.com|Owen's]] gcode parser and tool calibration and preview logic from [[https://github.com/jmpinit/projected-toolpath-preview|the original prototype]]. Here's how CNC tool calibration looks, where you move the machine to the 4 points and type their CNC coordinates in:

 It was in decent shape in December, so work on 3D calibration this month has involved a lot of small/polish tasks:

     * Replaces global mutex-protected priority queue; should be faster and better at natural load balancing across CPUs/threads, also lets us lock things to threads more cleanly
     * Also [[http://15418.courses.cs.cmu.edu/spring2017/lecture/progperf1/slide_019|these slides about how to deal with dependencies, scheduling in general]]

 In terms of functionality, it's surprisingly almost caught up to mainline Folk -- the real issues are around performance and correctness :-)
