Date: 2013-10-31

Agenda: up to you! What do you want to talk about?

* POSSIBLE AGENDA ITEM: plans for Tahoe Summit in SF.
* POSSIBLE AGENDA ITEM: let's do ChaCha20⊕AES ([//trac/pycryptopp/ticket/84 pycryptopp #84] and [ticket:1164 Tahoe-LAFS #1164]).
* POSSIBLE AGENDA ITEM: #1382 #1382 #1382 and #1382
* POSSIBLE AGENDA ITEM: Tahoe-LAFS over I2P, Tor, and/or cjdns by Twisted Endpoints ([http://foolscap.lothar.com/trac/ticket/203 pycryptopp #203]).
* POSSIBLE AGENDA ITEM: What can Nathan do to make progress on the 1.11 release process, given that there are still a few open blockers of tickets (notably #1382).
* POSSIBLE AGENDA ITEM: practical stateless hash-based digsigs (*Tesla Coils and Corpses*)
* Other possible agenda items: do code-review on the tickets that already have patches written for them! [milestone:1.11.0 Milestone 1.11.0]

This will be a ''"NUTS AND BOLTS"'' meeting — it is about engineering, debugging, documentation, making stable releases, etc.

If you're more into science, big new features, writing papers about our work, etc. then stay tuned for a future meeting about ''"TESLA COILS AND CORPSES"''.

  * fix defects in the WUI (#1993, #1931, #1375, #1462, #1502, #1961, #622, #311, #525, #631, #1588, #1645, #1706)
  * write cool new WUI (#1942, #1369, #1551, #1499, #277)

(I can't remember whether we actually followed the agenda.)

Possibilities: LDMF (fancier authenticated data structures), Brian's secret file-sharing project within Mozilla, !BitTorrent Sync, saying 'Okay, storage is good enough, let's work on decentralized currencies/payment-systems instead.'"

Actual topic turned out to be "Post-Bitcoin" instead.

* ''("TESLA COILS AND CORPSES")'': async notifications

What a ''lot'' of people really want is an alternative to Dropbox — something that functions very like Dropbox but without exposing your plaintext to spying and corruption. David-Sarah implemented a part of this with the drop-upload feature. It seems to me that the blocker which prevents Tahoe-LAFS from doing the rest of it is that LAFS clients have no way to get an asynchronous notification that a file has changed (i.e., so that they don't have to poll to find out if the file has changed). So: could we add that? Why not just define a remote interface offered by LAFS clients to LAFS servers. The remote interface is "hey_you_this_file_has_changed(storageindex)".

=== 2012-11-08 ===

''("NUTS AND BOLTS")'': 

* #1240; Is it done? (I think it still needs fixed tests.) Can we commit it to trunk and be done with it? Do we need to merge it with #1679?
* #1679; Let's write a test for it! Has The Dod had continuous good service since he applied the patch? Has nejucomo tried reproducing his bug and applying the patch?

=== 2012-11-01 ===

''("TESLA COILS AND CORPSES")'': **Garbage collection**: use cases and protocols;

* #1832 (support indefinite leases with garbage collection)
* #1833 (storage server deletes garbage shares itself instead of waiting for crawler to notice them)
* #1834 (stop using share crawler for anything except constructing a leasedb)
* #1835 (stop grovelling the whole storage backend looking for externally-added shares to add a lease to)
* #1836 (use leasedb (not crawler) to figure out how many shares you have and how many bytes)
* #1837 (remove the "override lease duration" feature)

And [//pipermail/tahoe-dev/2012-October/007768.html the associated mailing list thread].

=== 2012-10-23 ===

Topics: Ticket #1240, Tahoe-LAFS birthday party, future agendas.

Attendees: Zooko, David-Sarah, amiller, ambimorph, nejucomo.

Concise summary:

* #1240 debug session - Incorrect caching logic suspected.
* Tahoe-LAFS birthday party - Saturday, 2012-10-27 at 23:00z - Each locale connects with a projector + google hangout.
* Future agendas - next week, Proof of Retrievability paper review; two weeks out, Rainhill review with outside crypto reviewers.

Finely detailed notes in [wiki:MeetingNotes_2012_10_23]

Topics: Proof-of-Retrievability

Attendees: Zooko, David-Sarah, nejucomo

From IRC, Zooko summarizes (edited for spelling):

1. "The reason we can do better than the previous state of the art is that we've expanded the setting to multiple servers and multiple clients, which opens up new defenses for the good guys against Ponda Baba."
2. "It is useful way to think, to start with the completely safe camouflaged download protocol: just run your normal verifier, but tell it to save what it gets, and then to talk about how to make it faster without breaking camouflage."
3. "There are two dimensions of how you might be able to make it faster: the dimension of multiple downloader/verifiers and the dimension of multiple servers."
