Etiquette

  • It's okay to talk about things not on the prearranged agenda. (But it helps to announce in advance if you know there's something you'll want to talk about! It encourages other interested people to prepare and helps them avoid accidentally missing a meeting that they really would have wanted to attend.)

Upcoming

Date: 2013-08-21

Hangout URL: ​https://plus.google.com/hangouts/_/a94bc60114d1b91d8093af9d7a085d9052de84ea

Also we might want to start doing some ticket gardening for Tahoe-LAFS v1.11 release. There are hundreds (!) of unfinished tickets that need to be moved out of the 1.11 Milestone, plus several that might need to stay in as blockers since they are regressions.

To prepare:

  • read the patches referenced above

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".

Proposed Future Topics

  • Noether status report by Daira ("TESLA COILS AND CORPSES")
  • Rainhill design review which Daira will distribute; call for outside crypto expert reviewers ("TESLA COILS AND CORPSES")
  • Proof-of-Retrievability In The Presence Adaptive Adversaries by Zooko ("TESLA COILS AND CORPSES")
  • Awesome Generalized Authenticated Data Structures, Part 2 by Andrew ("TESLA COILS AND CORPSES")
  • Awesome Generalized Cryptocurrencies, Part 2 by Brian ("TESLA COILS AND CORPSES")

  • ("TESLA COILS AND CORPSES"): Agenda: "Post-LAFS: What would you invent (or are you inventing) now that you already understand Tahoe-LAFS? 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 the associated mailing list thread.

2012-10-23

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

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."
