Updates
===========================================

pastly:
   last 7 days:
   - sbws is now open source

       https://github.com/pastly/simple-bw-scanner

       https://sbws.readthedocs.io/en/latest/

   - fix some bad bugs in 'sbws cleanup' command while writing tests for it
   - integrate with Travis CI and automatically test against python 3.4,
3.5, and 3.6
   - integrate with Read the Docs
   - gather intel on the environments our users will be running sbws in


https://github.com/pastly/simple-bw-scanner/wiki/Information-regarding-sbws's-target-user-base

   - did some research regarding library support for various distros.
incomplete
   - remvoe filelock dependency
   - brainstorm what I think a switch to http(s) should look like

       https://sbws.readthedocs.io/en/latest/proposals/001-switchtohttp.html

    next 7 days:

    - start implementing the switch to http(s)

    - verify sbws works with library versions that aren't the absolute
newest

conf
      - report about problem with init and helpers #95
      - create issue about adding software to header #96
      - review using kilobytes #97, #98

  Past week:
      - fix conf issues locally and in testnet after "megacommit"
      - more changes on the spec, after new teor review
https://github.com/torproject/torspec/pull/4/commits/54ef4d4355d2b475466bf11e80ad4bc57c7e7ec3

  Next week:
      - debug what tor does to solve
https://github.com/torproject/torspec/pull/4/#issuecomment-384555243
      - review the software/version ticket according to results from
previous (https://github.com/pastly/simple-bw-scanner/issues/96)
      - review spec according to results from previous
      - add a default output file for generate that can be overriden by
cli args (https://github.com/pastly/simple-bw-scanner/issues/91)
      - improve deployability, this should also help to update instances
running in testnet (https://github.com/pastly/simple-bw-scanner/issues/99)
      - update version sbws running in testnet

    Things to communicate:

     - i put as date of sbws release 1.0.0 (milestone 1) 1st May, but
i'd postpone

       to later so that we've more time testing and fixing last details

     - teor, can i make public the list of tasks you've proposed for
SoP?, any place you would propose?

     - pastly: It's fine to close issues/PRs you think aren't apropiate
for any reasons, but please say so before closing (#111, #87)

     - i stop attending net-team meetings until we need to disscuss
something there that we don't discuss in this meeting


    List of tasks for 3 months proposed by T. (19th Apr)


    - implement features we wanted in torflow in sbws instead (1 week)
      - bwauth code needs to be smarter about failed circuits
https,//trac.torproject.org/projects/tor/ticket/16559
      - assign the 10-second client timeout as the time for failed circuits?

      - at least publish failure rates
https,//trac.torproject.org/projects/tor/ticket/7281

      - Understand how accurate the bandwidth authority estimates are
https,//trac.torproject.org/projects/tor/ticket/7177
    - integration tests (1 week)
    - a practice transition in the test network (1 week, but split up)
      - set up torflow
      - set up sbws

      - compare and switch
    - work little-t tor needs (3 weeks)
      - report version of bwscanners in votes
https,//trac.torproject.org/projects/tor/ticket/3723
      - stop relays reporting zero observed bandwidths
https,//trac.torproject.org/projects/tor/ticket/24250
      - relays should regularly do a larger bandwidth self-test
https,//trac.torproject.org/projects/tor/ticket/22453
      - bandwidth testing circuits should use guards sometimes
https,//trac.torproject.org/projects/tor/ticket/19009
      - report bandwidth more often on test networks
https,//trac.torproject.org/projects/tor/ticket/17036

      - report bandwidth less often on large, public relays
https,//trac.torproject.org/projects/tor/ticket/24104
    - non-essential tickets like
https,//github.com/pastly/simple-bw-scanner/77 and
https,//github.com/pastly/simple-bw-scanner/48 (2 weeks) - if time and
motivation
      - Have sbws client launch tor itself
https,//github.com/pastly/simple-bw-scanner/77
      - Evaluate using [not threads, but twisted instead (probably)]
https,//github.com/pastly/simple-bw-scanner/48

teor:
    last week:
        * made my test dirauth a trust pastly's and juga's dirauths
        * monitored the average bandwidth on the testnet using this
script: https://pad.riseup.net/p/tor-vote-bw-average
        * opened a ticket for getting similar features into
consensus-health: https://github.com/pastly/simple-bw-scanner/issues/120
    this week:
        * busy with deadlines
        * eventually try to set up sbws on the testnet


Discussion
=========================================

### Topic: Switch to HTTP(S)

### (Proposed) Topic: SoP
- specific topics on this?
pastly: where can I find your proposed schedule again?
juga: mail
pastly: finally found it
 - personally i'm not sure on how to organize the tasks we've said i'll
do for SoP, since that's in a month. Either i do now other stuff not
included there (doing so so far), or i start with those tasks and then
update to others during SoP
