Dependencies

[flyingzumwalt]

@nicola is also on this sprint -- couldn't add him as an assignee because he wasn't a collaborator on this repo yet (waiting for confirmation of invite)

[nicola]

Was "IPLD Selector Spec" really part of this sprint?
I happen to be doing work on this in the past few days, I thought we did not consider it

[daviddias]

IPLD Selector Spec, get bitswap to use it

I don't know how they appeared in the list.. I didn't have any discussion that it would be a goal of the sprint. Yet, we might do a lot of work or even push ourselves to do it.

[daviddias]

@nicola did you remove yourself from this Sprint?

Prep session doodle http://doodle.com/poll/yk6xu87q3xxrqyhk

@whyrusleeping @nicola please add your availabilities.

[nicola]

@diasdavid I will be in Palo Alto (sorry for the bad timing)

[whyrusleeping]

@diasdavid I don't think i can make any of those times, The most likely is 10am friday morning (the rest of the times are all too early in the morning) but i don't have more than an hour of availability there.

[daviddias]

@whyrusleeping 9am doesn't work for you? What about right after the all hands? Any proposed solution?

[daviddias]

Added another hour (yours 10pm Thursday) http://beta.doodle.com/poll/yk6xu87q3xxrqyhk @nicola @whyrusleeping

[daviddias]

@whyrusleeping need your input (urgent) on https://github.com/ipfs/interface-ipfs-core/issues/81

Also, can I get those 'test graphs'?

[daviddias]

@whyrusleeping, @Gozala is trying to resolve base16 encoded values in CIDv1, but without success, I also tried and no go, what are we forgetting here?

From IRC

21:58 <gozala> daviddias: Ping!
21:58 <gozala> daviddias: I’ve tried to use [email protected] but still don’t seem to get it to do what I wanted
21:59 <gozala> daviddias: here is the snippet of code https://runkit.com/gozala/58645fba7240320014993626
21:59 <gozala> daviddias: I’m essentially trying to take this address http://localhost:8080/ipfs/QmPZ9gcCEpqKTo6aq61g2nXGUhM4iCL3ewB6LDXZCtioEB
22:00 <gozala> and transcode it to base 16 to have all lower case
22:00 <gozala> http://localhost:8080/ipfs/f1701220120f6af601d46e10b2d2e11ed71c55d25f3042c22501e41d1246e7a1e9d3d8ec
22:01 <gozala> but when I do so go-ipfs 0.4.4 fails to resolve path with: not a key error
