Your other post; verycool old phone; I to have several flip phones |
| 30 |
an LG still 'on service. JTAG interfaces to the hardware is even cooler. |
| 31 |
Gotta get a giant magnifier for that sort of access work. |

Glad to have helped. If you get into EXIF data. |
| 36 |
check out "photogammetry" as 2d still photos can be 'stitched' together |
| 37 |
to create awesome 3D and 3D+motion models. One of the key usages of HPC. |
| 38 |
If I can only stay healthy.... SfM (structure from motion) is my latest |
| 39 |
addiction.... |

| 41 |
It's just very very cool technology. Some folks are building 3D-motion |
| 42 |
models of the inside of their lab. Cover the wall with monitors |
| 43 |
and then animate the objects inside, work remotely (like a VR game) or |
| 44 |
walk into the home_lab and work as normal. Building your own, is where |
| 45 |
the fun is. Get a UAV pilot's license and a sub 1K drone and well, just |
| 46 |
let your imagination go wild! |

gqview -- nice piece of old software. I'll have to check it out.. |
| 50 |
it's age on sourceforge is a bit to worry about. I'd pack it up and |
| 51 |
put it in /usr/local/.... or at least into a github/gitlab/gogs or |
| 52 |
wherever you archive codes. Lots of stuff is disappearing now, related |
| 53 |
to geo-tagging and image processing. I've pretty much settled on |
| 54 |

Surely there are plugins for palemoon that yield up EXIF data? |
| 58 |
(btw palemoon-28.0.0 is very stable). Here are some random points of |
| 59 |
interest,should your 2D images lead to 3D and beyond; here's a good intro:: |

All of this on gentoo? Sure, that's why I'm working on |
| 79 |
Hybrid-heterogeneous HPC gentoo clusters. But I'm AMD_Radeon_arm64 open |
| 80 |
source centric with my work. I'd be most appreciated if anyone can add more |
| 81 |
detail, list of FOSS codes, or other related packages and details. |
