2·14 days agothe more i think of it the more i doubt the sandstone again. i found this in a bigger region of high grade metamorphic rocks (mostly amphibolite, granulite). the specific place is a quarry where they quarry serpentinite as gravel. the rock unit is extremely busted up and crumbles basically on light touch into fist and smaller sized chunks. this rock, whatever it is, formed in cracks between the serpentinite. also for a straight forward sandstone this has a lot of mica in it and there are bands of nearly pure mica. i need to see if i can make take a picture with the microscope tomorrow.

2·14 days agoalright! sandstone then. it doesn’t have limestone though. nothing on that rock reacts to acid

2·14 days agoi posted a few microscope pictures up top. what i neglected to mention is that the stretched crystals recrystalize, so single crystals won’t lock stretched under the microscope. but you can (maybe) see the white crystals, which is quartz, then some brownish stuff, which is either impure quartz or mica crystals, and some black platey stuff, which may be biotite mica
but please: see disclaimer in above post. i could be talking out of my ass

4·14 days agoDisclaimer: So, I am very interested in this topic but i am no petrologist or anything. So take everything I say with heaps of salt. But:
From what I understand though it’s different materials. Gneiss is highly metamorphosed, meaning subjected to high heat and/or high pressures. So the source rock (often granite) is squeezed and stretched and the discrete crystals stretch into this layers. It’s also pretty easy to see under any optical magnification, that there are different types of crystals and minerals in the different bands. At least to the untrained eye it looks like it.

Programming@programming.dev•Forget "gif" vs "jif" debate. How does one pronounce "Forgejo"?
15·1 year agoOn the official page it says that it is pronounced For Jay Yo (at least close enough)
that’s your interpeetation. what’s missing for me is “must be freely (as in not only by specific entities) obtainable”. with this wording i could just say: “this data is not obtainable” and be done with it.
no it doesn’t. it only says the weights an information about the training data must be open, not the training data itself. which is honestly useless.

52·1 year agothis is the attack on stallman
seems prett damning to me
also i’m going to let devault himself rebut this
also no: stallman being under attack for credible accusations and even non-retracted public statements is not an “attack on free software” but a much needed clean up. call it a refactoring of legacy assets, if you want.
