JTAG interfaces to the hardware is even cooler. Gotta get a giant magnifier for that sort of access work. Glad to have helped. If you get into EXIF data. check out "photogammetry" as 2d still photos can be 'stitched' together to create awesome 3D and 3D+motion models. One of the key usages of HPC. If I can only stay healthy.... SfM (structure from motion) is my latest addiction.... It's just very very cool technology. Some folks are building 3D-motion models of the inside of their lab. Cover the wall with monitors and then animate the objects inside, work remotely (like a VR game) or walk into the home_lab and work as normal. Building your own, is where the fun is. Get a UAV pilot's license and a sub 1K drone and well, just let your imagination go wild! gqview -- nice piece of old software. I'll have to check it out.. it's age on sourceforge is a bit to worry about. I'd pack it up and put it in /usr/local/.... or at least into a github/gitlab/gogs or wherever you archive codes. Lots of stuff is disappearing now, related to geo-tagging and image processing. I've pretty much settled on [ https://gogs.io ] Surely there are plugins for palemoon that yield up EXIF data? (btw palemoon-28.0.0 is very stable). Here are some random points of interest,should your 2D images lead to 3D and beyond; here's a good intro:: https://www.prusaprinters.org/photogrammetry-3d-scanning-just-phone-camera/ Here is the latest read on mixed reality:: https://software.intel.com/en-us/blogs/2018/06/18/siggraph-2018-the-state-of-photogrammetry-in-real-time-graphics And if intel machines get 'out of control' well, we'll just have to jolt the some electrons with odd_spin:: https://github.com/ptresearch/IntelTXE-PoC All of this on gentoo? Sure, that's why I'm working on Hybrid-heterogeneous HPC gentoo clusters. But I'm AMD_Radeon_arm64 open source centric with my work. I'd be most appreciated if anyone can add more detail, list of FOSS codes, or other related packages and details. hth, James
