Weekly Meeting

There is a weekly videoconference, currently using ​Jitsi. The server details are available on 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 Jitsi, IRC fallback
Why Voice/video interaction complements IRC/mailing list
How See Agenda below
IRC join channel "#tahoe-lafs" on irc.libera.chat (port 6697 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)

Old agendas are posted here for the historically curious. Recent meetings don't necessarily have as well-defined an agenda set in advance. Please feel free to suggest items for discussion via any communications channel.

We usually meet in ​https://meet.jit.si/AccurateFiltersManipulate (but open to other Jitsi hosts or different video+voice services).

Notes from 2024 Meetings

February 6, 2024

attendees: meejah, chris

Open-ended discussion / brainstorming about:

  • aspects of magic-folder conflict resolution (for >2 party conflicts).
  • very broad outline of work required to be able to specify keys for mutable directories
  • general next steps for both of the above:
    • chris will be looking into Rust library + Python bindings for BIP39 -> key transforms
    • meejah working through test-cases for magic-folder conflict resolution
    • medium-term: Gridsync / UX for above

January 30, 2024

attendees: meejah, ccx, hackleschorsh, chris

  • discussed current and future work (i.e. what people are working on now and what they want to work on in future)
  • meejah: familiarizing with magic-wormhole and magic-folders so a new release can be produced; reviews and bug-fixes related to 1.19.0 release bugs (cbor2, ...)
  • chris: will likely be looking at "recovery phrases" soon (so one can specify the private-key for a mutable using BIP39 style words)
  • ccx: interested in share-placement, especially related to "repair"
  • hackleschorsch: interested in packaging
  • some (re-)discussion of self-hosting / moving from tahoe-lafs.org Trac instance to something else (e.g. sourcehut, forgejo, gitea, gitlab, ...)
  • clarity around timing of this meeting (including a calendar file somewhere, e.g. on this wiki). (we actually started at 1800UTC today, which works for these attendees)

Historical Content

Agenda for next meeting (30-Aug-2016)

  • tor/i2p client support landed! #2788, #517
  • #2816 (disable listener): are folks comfortable with the syntax?
  • #1010 (anonymous mode): discuss the proposed semantics
  • discuss what other anonymity code needs to land before release: #1942, #2384, #2490 (create-node/create-client CLI args), #2773 (create-node --port/--location/--hostname)
  • #2815 (document manual config of .onion server)
  • at what point can we close #517?
  • multi-introducer: can we just use tahoe.cfg introducer.petname1.furl= lines?
  • #68 (introless): can we just omit introducer.furl= ?
  • check in with Daira on status of cloud-backend branch
  • Science Hour: agoric-mode tahoe grid: minimum BTC/ETH txn fees limits number of payment relationships: discuss

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

  • #1382 #1382 #1382 and #1382; It is almost done. Is it done? Maybe we need one more round of code review‽ Can we merge it?

  • do code-review on the tickets that already have patches written for them! Milestone 1.11.0
  • POSSIBLE AGENDA ITEM: Tahoe-LAFS over I2P, Tor, and/or cjdns by Twisted Endpoints (​pycryptopp #203) because ​https://pypi.python.org/pypi/txi2p exists now!
  • POSSIBLE AGENDA ITEM: let's do ChaCha20⊕AES (pycryptopp #84 and Tahoe-LAFS #1164).
  • 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")

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.

Finely detailed notes in MeetingNotes_2012_10_23

2012-10-16

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."
