Your other post; verycool old phone; I to have several flip phones an LG still 'on service. JTAG interfaces to the hardware is even cooler. Gotta get a giant magnifier for that sort of access work. <snip> 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/ <lots of codes in portage, hit me up if you are interested in more> 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
