00:19:23	Brent Shambaugh:	https://github.com/bytecodealliance/wasm-tools is useful?
00:20:28	Zeeshan Lakhani:	Brent, most definitely. I use it all the time to work w/ was mods. But, on those specs/docs: https://github.com/WebAssembly/component-model is the component model. The WIT format is covered here: https://github.com/WebAssembly/component-model/blob/main/design/mvp/WIT.md.
00:21:25	Brent Shambaugh:	So is the link you provided the place to dive in?
00:21:25	Zeeshan Lakhani:	This guest-wasm crate: https://github.com/ipvm-wg/homestar/tree/main/homestar-guest-wasm, is essentially a small, setup working w/ wits and compiling to wasm. I plan to doc it more too
00:22:06	Brent Shambaugh:	ahh...okay, that sort of answers my question I think. Thanks Z.L.
00:22:43	Bastien Dehaynin:	Link to Starmaps: https://starmap.site/roadmap/github.com/fission-codes/Fission-Starmaps/issues/8?crumbs=%5B%5B%22fission-codes%2FFission-Starmaps%231%22%2C%22Fission+Projects+%22%5D%5D#simple
00:30:12	Zeeshan Lakhani:	Term comes from this Ambrosia paper from Microsoft: https://www.microsoft.com/en-us/research/publication/a-m-b-r-o-s-i-a-providing-performant-virtual-resiliency-for-distributed-applications/ | good writeup here: https://christophermeiklejohn.com/pl/2018/12/15/ambrosia.html
00:33:39	Brent Shambaugh:	https://github.com/ipvm-wg/homestar/#testing-the-project Is the idea to write random code (turing complete) and convert it to WASM and then send it to IPVM where it automagically executes? is the an example folder somewhere, or is it still too early?
00:34:33	Brent Shambaugh:	do you have to think about if your code can be parallized?
00:35:43	Melanie Riise:	parallization should be done above the recipt level, lower level parallization is harder :(
00:40:17	Brent Shambaugh:	so the program is a CID, and the result is stored in a CID
00:40:42	Melanie Riise:	yes
00:41:30	Melanie Riise:	input to the program would be a CID as well
00:42:04	Zeeshan Lakhani:	Yep, could be a CID or direct IPLD params / either/or
00:43:37	Brent Shambaugh:	actually, I don't know that much. the CID is a hash. somehow it has to resolve to something (and then loaded in IPVM?). for some reason resolution is something that is a bit fuzzy to me, but I am sure it is in the IPFS and/or IPLD docs somewhere.
00:44:08	Melanie Riise:	DHT primarially
00:45:56	Brent Shambaugh:	okay, like gossiping around and matching against the hash since creation is deterministic (sorry on a tangent)
00:46:04	Melanie Riise:	in theory IPVM could connect to source with known CIDs of common/expected WASM modules
00:50:04	joel:	Fluence?
00:50:50	Brent Shambaugh:	I started thinking about semantic overlay optimization of DHT (Kadmelia based on chord IIRC is not optimized for that)... but real tangent. might have to ask at casual islands ...
00:51:12	Melanie Riise:	content routing is 100% a fun rabbit hole
00:52:24	Brooklyn Zelenka (@expede):	It’s “The Graph”!
00:53:34	Melanie Riise:	"Explore the Merkle Forest" - IPLD people
00:55:48	Simon Worthington:	It sure does… about 40 extensions to the WASM spec right now, all with varying degrees of support
00:56:04	Melanie Riise:	are GUIs in scope? lolol
00:58:14	Simon Worthington:	Our notes on “plugins” and describing “features” from Bacalhau land: https://pl-strflt.notion.site/Multi-platform-jobs-and-nodes-a834817e21ad4f33a1976bcb05bf35be
00:58:25	Simon Worthington:	Broadly: what you said Brooklyn :)
00:58:35	Melanie Riise:	WASM is good at polyfill (thanks browsers!) so we can get a _lot_ of compatability fairly easily (in theory)
00:58:43	Brooklyn Zelenka (@expede):	Melanie: GUI is not in scope for IPVM… but you can totally build on top of it! We’re planning on doing a demo along those lines at IPFS Thing
00:58:54	Brooklyn Zelenka (@expede):	Reacted to "WASM is good at poly..." with 💯
00:59:55	Melanie Riise:	oooo, then I'll give you a peak at what im playing with once its actually rendering things :)
01:00:05	Brooklyn Zelenka (@expede):	Reacted to "oooo, then I'll give..." with 🎉
