Weekly Meeting

There is a weekly videoconference, currently using ​Google Hangout. The connection URL is posted on this page and IRC a few minutes before the meeting.

Who Core developers or interested community members
What Dev Topics Meeting
When Tuesdays 16:00Z-18:00Z (in summer. one hour off in winter)
Where Google Hangout, IRC fallback
Why Voice/video interaction complements IRC/mailing list
How See Agenda below
IRC join channel "#tahoe-lafs" on irc.freenode.net (port 7000 for TLS)

(Z "Zulu" time refers to UTC; ​check where you are, but the meeting is tied to civil time, not UTC, so when the various countries all switch to/from DST, the meeting's UTC time changes)

The first half of the meeting is "Nuts and Bolts" (engineering!): bug triage, discussion of current development efforts, branch and patch review, etc. After a short break, we switch to "Tesla Coils and Corpses" (science!): brainstorming of new features, analysis of other projects, and other forward-looking explorations.

Agenda for next meeting (26-Jul-2016)

  • topic 1
  • topic 2

Other Stuff

We switch chat tools every few months, in an attempt to overcome performance problems. Tools we've used:

Most require a browser extension to enable screensharing.

We frequently keep notes on an etherpad, the URL for which is posted at the start of the meeting. Patrick McDonald? turns these notes into the Tahoe Weekly News.

Other resources that usually get referenced during the course of the meeting:

Proposed Future Topics

  • ("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.

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.

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."
