RE: Agenda for our telcon today

Folks,

The telcon today was brief and participation was limited - David K, Jonathan and I were present.
We discussed the proposed items on the agenda:

-          Status update - there was an announcement from Google regarding updated Brotli codebase and availability of the draft spec [1]. Please review the draft and provide your comments on it (Sergei M., it would be great if you could also share this news within your team to see if you can get some extra eyes to look at it from the implementation and security standpoint). As a follow up to our previous discussion about IETF / RFC way of publishing the spec (and after getting the internal consensus within Google) - it was suggested that we should try to do the "information only" RFC as it may be sufficient considering the open source nature of the Brotli project.

Action Items: a) clarify the IP positions and licenses that are relevant to Brotli, and b) ask Chris L. if information only RFC (which is similar to how zlib is spec'ed) would be sufficient to be used as a normative reference for WOFF 2.0 recommendation.

-          All open action items remain unchanged until we can get a quorum for the WG telcon;

-          On-curve point optimization: The initial results are encouraging and warrant further consideration. I will run the tool on a larger font set to collect more meaningful stats; meanwhile David, Jonathan and I agreed that it would make sense to implement the optimization as part of Brotli codebase and see what the actual compression gains (after both the pre-processing and entropy coding steps) would be. It is assumed that on-curve point optimization gains associated with eliminated coordinate numbers would be complimentary to entropy coding but if the majority of the coordinates are expressed as deltas (i.e. repeating incremental steps) the entropy coder may be able to take good care of them. Once we know what the real-world effect is, we will make a final determination if it's worth keeping this step as part of the WOFF 2.0 pre-processing optimization.

Our next call will be next week, Wednesday Dec. 11 at http://www.timeanddate.com/worldclock/fixedtime.html?iso=20131211T10&p1=43&ah=1

Thank you,
Vlad
