I'm giving up maintainership of the #Subsurface dive log package on #Flathub. There is a too wide gap between how it is developed and what Flathub/Flatpak expects, and I still can't use the Flathub version with my own dive computer because there are Bluetooth issues I have no idea how to debug.

I cannot justify investing more time on an application I use at most three times a year. Especially when the official #AppImage just works.

Life is thriving in the subsurface depths of Earth

Different species thrive beneath the oceans than under the land.

Life does not end at the #sediment-#water-interface, it keep going down and down and down (less so on land). There is a #diversity continuum, and some of those #subsurface #microbial communities can be rather diverse.

Observed archaeal and bacterial richness across environments based on 16S rRNA gene ASVs.
Archaeal (A) and bacterial (B) richness found in the 11 studied environments (n: number of included samples). Environments are grouped on the basis of biome (marine, terrestrial) and depth realm (surface, interface, subsurface). Note that Archaeal terrestrial water and sediment samples contain too few datapoints for robust visualization using boxplots, yet the plots were retained for completeness. NA, no value available. Total archaeal (C) and bacterial richness (D) using a subsampling approach to account for different group sizes (100 iterations using 1142 archaeal or 2271 bacterial reads, respectively). Normalized gamma diversity corroborates that archaeal diversity is highest in marine interface and subsurface ecosystems even when different group sizes are considered. All pairwise comparisons were significantly different (P < 0.001) except for those indicated with ns (not significant).

@bagder you forgot to mention #subsurface on your List. 😊

#subsurface is usable on #linuxonmobile. Screenshot from a #Furilabs #FLX1. I wonder if importing dives via Bluetooth also works.

I've been maintaining the Subsurface package on #Flathub for about a year now.

I just published a blog post outlining my reasons for logging dives and how to setup Subsurface, the best software I've found for digital logging. Enjoy and feel free to drop any questions or comments here!
