There are a number of unaddressed questions on Piazza concerning Midterm 2 grading/answers and the final project. Will you or the TA address these soon?
Nathan Hunter
14:57
Should we be forming groups?
Gary Fitzgerald
15:38
Do we need to have 4, or can it be between 2 and 4?
Daniel Graham
16:10
4
Seth Dolin
16:28
Can you make the instructions for the Torrent client modification project available even if it's not going to be graded?
Jake Moses
19:42
Are you by default in a torrent
Jake Moses
19:47
Or how do you join a turrent?
Seth Dolin
22:35
Once a client is in the torrent does it still need to make contact with the tracker for any reason?
Seth Dolin
26:00
Do all peers have the entire table? Or is it chunked just like the torrent itself?
Jake Moses
31:40
What are the keys tracking again? The peers themselves?
Jake Moses
33:09
Thank you!
Seth Dolin
33:11
So are the values the set of peers that have parts of that file?
Jessica Krynitsky
33:42
how are the peer IDs assigned?
Seth Dolin
36:55
But wouldn't 12 know that 1's predecessor could wrap around and be larger?
Nathan Hunter
37:30
O(n)
Nathan Hunter
39:16
Can everyone have everyone's key?
Jessica Krynitsky
39:32
Could you do something like a binary search query?
Catherine Rogers
39:33
Is there some way to use a binary search?
Andy Tan
39:36
binary search in the ID space
Seth Dolin
39:59
You could maybe get linear factor of time reduction by having each peer track 2+ predecessors and successors and then jumping more than 1 peer at a time
Seth Dolin
41:25
How does this network structure handle clients dropping out?
Seth Dolin
41:59
OK
Josh Laney
45:23
do you also have to know two predecessors?
Jake Moses
45:34
And 3s successor’s successor becomes 8 right?
Jake Moses
57:05
On a separate note, could you post the slides after class so we could click back through them and get notes we missed?
Jake Moses
57:47
thanks!
Nathan Hunter
01:03:55
How do you get files to share with others in the first place? And if you aren't optimistically unchoked, do you have a hope of ever getting what you need?
Jake Moses
01:12:46
Can you upload the pdf too
Jake Moses
01:12:48
Of the slides?
Jake Moses
01:12:54
Thank you!
Andy Tan
01:13:37
Thanks have a good day
