he didn’t say that

he said once that static analysis of c++ is not possible because of the halting problem though

and he did create c++, which i use daily

i find it to be the language for other languages to learn how to absolutely not do it

it is the programming equivalent of that first scene in scary movie 1 where the woman first picks the banana instead of the gun and then runs in the direction “danger” instead of “safety” and gets run over by her distracted dad getting a blowjob in the car

mmmmh vesicular basalt ❤️

I don’t know. Petrified wood isn’t all that common. Why do you think it’s that?

To me it looks like a finegrained, silicious, sedimentary rock. Might be slightly hydrothermally altered or metamorphosed, can’t really tell from the photos.

That’s not to take away from the coolness of the rock though. It absolutely is a cool rock. I absolutely adore that quartz vein.

I think it’s some kind of (maybe hydrothermally altered) sandstone.

That vein is quartz, i’m pretty sure. Does the rest have a slightly grainy texture or is it smooth?

are there any (hard) rocks that don’t tumble well? like i get that chalk or soft limestone or something might not be the brightest idea. but have you tried anything except crystals? i’d be interested how e.g. gneiss or granite tumble. i mean it’s obviously dependend on the specific rock but still

So, of the two JavaScript, because motivating them to program is more important than anything else if they have no prior knowledge. javascript has great tooling and faaar less hurdles to get something going then C. Personally i’d go with TypeScript if it has to be anything in this family of languages, because making them think of types early on is helpful when moving to anything more than little web apps. If any other languages are considered, i’d go with python with type hints because it forces you to format your code somewhat readably (believe me, i know that it’s possible to write unreadable python code) but is really low on boilerplate, has great tooling (at least third-party, use uv) as well as stellar IDE support and allows for multiple different paradigms to be explored.

nope… that’s just local.

in that regard every text editor or any software that just CRUDs files locally would be local-first and the term would be meaningless

local-first means that it does not need internet-access to work and use the app and synchronization comes later, when there’s time and internet access. please read up on this.

these are the guys who coined the term

edit: i originally wrote “local-first means that it does need internet-access to work and use the app…”, which is bullshit and also doesn’t make sense in the context. i added the “not” so it is clear.

If you have to use a third party app to sync, it’s not local-first, it’s just local.

boring answer: halite (salt)

spice answer: arsenolite

please don’t lick, eat or otherwise consume arsenolite…

very nice

top most and both lower middle and lower left could be upper middle looks like marble lower left looks like a sandstone

oh cool! Flint nodule?

Super cool! The banding, the conchoidal fracturing and the vitreus (glassy, 10$ word, payable in nice rocks or cash) luster says agate to me.

looks a little like schist

it is limestone! tested it with acid. weird color for it though

great! thanks!

the 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.

alright! sandstone then. it doesn’t have limestone though. nothing on that rock reacts to acid
